California Payroll — Employer Compliance (Tax Year 2025)

1. Scope

This skill covers California employer payroll compliance for the 2025 tax year, including:

• California Personal Income Tax (PIT) withholding administered by the Employment Development Department (EDD)
• State Disability Insurance (SDI) and Paid Family Leave (PFL) — bundled, employee-paid
• State Unemployment Insurance (SUI) — employer-paid, experience-rated
• Employment Training Tax (ETT) — employer-paid, on first $7,000
• Form DE 9 (Quarterly Contribution Return and Report of Wages) and Form DE 9C (Quarterly Contribution Return and Report of Wages — Continuation)
• Form DE 4 (Employee's Withholding Allowance Certificate) — California's W-4 equivalent
• DE 88 deposit coupons and e-Services for Business deposit cadence
• CalSavers retirement mandate (Government Code §100000 et seq.)
• AB5 / ABC test for independent contractor classification (Labor Code §2775 et seq., Dynamex Operations West, Inc. v. Superior Court, 4 Cal.5th 903 (2018))
• DE 542 (Report of Independent Contractor) for $600+ payments
• California wage-statement requirements (Labor Code §226)
• Final pay rules and waiting-time penalty (Labor Code §201-203)
• Workers' compensation overview
• Local tax overlays for San Francisco (Gross Receipts Tax, Payroll Expense Tax) and Los Angeles City Business Tax — referred out

Out of scope (refuse or refer out):

• Federal employment tax filing (Forms 941, 940, 943, 944, W-2/W-3 transmittal) — see us-federal-payroll (separate skill) or refer to credentialed payroll provider
• Multi-state nexus apportionment of payroll (employee working partly in another state) — refer to credentialed payroll professional
• Public-sector / governmental employer payroll (special rates, special funds)
• Agricultural employers under the Agricultural Labor Relations Act (separate rules)
• Tipped employee minimum-wage interaction with federal FLSA tip credit (CA does NOT allow a tip credit — refer-out for FLSA-CA interaction beyond the basic note in §13)
• Cannabis employer payroll (special licensure interaction)
• Garnishment and child-support withholding administration beyond noting the obligation exists
• ERISA-governed retirement plan administration (different from the CalSavers mandate, which is non-ERISA)
• H-1B / J-1 visa and totalization-agreement payroll edge cases
• Stock option §83(b) elections and §409A deferred compensation (refer to equity comp specialist)

Prerequisites: This skill MUST be loaded alongside us-tax-workflow-base v0.2 or later. It assumes a human reviewer credentialed under Circular 230 (EA, CPA, or attorney) or a CA-licensed payroll professional / SHRM-certified HR practitioner reviews and signs off every output before it reaches the employer or the EDD.

2. The Four California Employer Payroll Taxes (Quick Map)

California payroll taxes administered by the EDD fall into four buckets. Two are paid by the employee (withheld), two are paid by the employer.

Tax	Who Pays	2025 Rate	2025 Wage Base	Notes
PIT (Personal Income Tax)	Employee (withheld)	Per DE 4 / DE 44 tables; supplemental flat 10.23% (or 6.6% for bonuses non-equity, but EDD has consolidated to 10.23% effective for all supplemental wages); top marginal 13.3% incl. MHST	No cap on wages subject; bracket-based	Mental Health Services Tax 1% over $1,000,000
SDI / PFL	Employee (withheld)	1.1%	NO WAGE CAP (SB 951 removed cap effective 2024 and continuing 2025)	Includes Paid Family Leave
SUI (UI)	Employer	New employer 3.4% for first 2-3 years; experience-rated 1.5%-6.2% thereafter	$7,000 per employee per year	UI Trust Fund; CA fund is currently in deficit and FUTA credit-reduction state in 2024 (carryover risk for 2025)
ETT (Employment Training Tax)	Employer	0.1% (positive-reserve employers only; negative-reserve employers are exempt)	$7,000 per employee per year	Funds workforce training

In addition, the employer must also withhold and remit federal taxes (FIT, FICA Social Security 6.2% to $176,100 in 2025, Medicare 1.45% + 0.9% additional, FUTA 6.0% with 5.4% credit on first $7,000) and observe federal Form 941 / 940 / W-2 obligations. Those are covered in us-federal-payroll (separate skill); this skill stays in the California lane.

Key 2025 mnemonic: "PIT and SDI come out of the employee's pocket; SUI and ETT come out of the employer's pocket." The two employer taxes share the same $7,000 wage base. SDI lost its cap in 2024 and remains uncapped in 2025.

3. CA Personal Income Tax (PIT) Withholding

3.1 Authority and Method

PIT withholding is governed by California Revenue and Taxation Code §18661 et seq. and Unemployment Insurance Code §13020. The EDD publishes the withholding method in Publication DE 44 (California Employer's Guide) and the bracket-and-table schedules in DE 44 Appendix.

Employers must withhold using one of three methods:

1. Method A — Wage Bracket Tables (per DE 44). Suitable for most pay periods.
2. Method B — Exact Calculation Method (per DE 44). Required when wages exceed the top wage-bracket entry. Most payroll software uses Method B.
3. Supplemental flat rate for supplemental wages (bonuses, commissions, stock-based comp not paid with regular wages): 10.23% in 2025.

3.2 2025 California PIT Brackets

The 2025 California marginal brackets (single filer; MFJ doubles most thresholds; head of household intermediate) used for withholding tabulation:

Single Bracket (Taxable Income)	Marginal Rate
$0 — $10,756	1.0%
$10,756 — $25,499	2.0%
$25,499 — $40,245	4.0%
$40,245 — $55,866	6.0%
$55,866 — $70,606	8.0%
$70,606 — $360,659	9.3%
$360,659 — $432,787	10.3%
$432,787 — $721,314	11.3%
$721,314 — $1,000,000	12.3%
Over $1,000,000	12.3% + 1.0% MHST = 13.3%

The Mental Health Services Tax (MHST) under R&TC §17043 applies a flat 1% surtax on taxable income exceeding $1 million. Withholding tables build this into the top wage brackets, but for executive compensation and equity events the supplemental withholding mechanic (below) generally undercollects, leaving the employee with a Form 540 balance due. AUDIT FLASH POINT — see §3.5.

Bracket figures above reflect FTB inflation indexing publicly available as of the skill's last_updated date. If your client engagement falls in a window where the FTB has released updated indexed brackets and the EDD has issued a revised DE 44 Appendix, refresh and disclose the figures used.

3.3 Form DE 4 — Employee Withholding Allowance Certificate

Form DE 4 is California's analogue to federal Form W-4. It is REQUIRED in addition to (not instead of) the federal W-4 when:

• The employee claims a different number of California allowances than federal allowances
• The employee is exempt from California withholding but not federal (or vice versa)
• The employee wants additional CA withholding withheld
• The employee is a nonresident performing services in California (special rules; refer-out for nonresident apportionment)

If no DE 4 is on file, the employer defaults to the filing status and allowances on the federal W-4 (with adjustments per DE 44 Section B). A common error is treating the post-2020 federal W-4 (which eliminated personal allowances) as zero CA allowances — the EDD instructs employers to use the DE 4 filing-status and allowance structure independently, so a DE 4 is now effectively required for any employee who wants accurate CA withholding.

The DE 4 is retained by the employer (not submitted to EDD) but must be available on request. If withholding allowances exceed 10, the employer should send a copy of the DE 4 to the Franchise Tax Board within 20 days under R&TC §18664.

3.4 Supplemental Wage Withholding — 10.23%

Supplemental wages are wages paid in addition to regular wages and include bonuses, commissions, overtime when paid separately, severance, accumulated PTO payouts, retroactive pay, and most equity compensation events (RSU vesting, NQSO exercise spread, ESPP disqualifying disposition).

The mandatory California supplemental withholding rate for 2025 is 10.23% for all supplemental wages. (Prior to 2018 California maintained a separate 6.6% rate for non-stock-option supplemental wages and 10.23% for stock options and bonuses; the EDD has since consolidated to a single 10.23% rate for most supplemental wages. Confirm against current DE 44 because the EDD has been known to adjust this.)

For supplemental wages paid concurrently with regular wages, the employer may either:

• Aggregate the supplemental wages with the regular paycheck and compute total withholding under Method A/B, OR
• Use the 10.23% flat rate on the supplemental portion only.

For separate supplemental payments (a standalone bonus check, equity vest run through a brokerage), the 10.23% flat rate is required.

3.5 AUDIT FLASH POINT — Equity Compensation Undercollection at the Top Marginal Rate

The 10.23% supplemental rate is materially below the 13.3% top marginal rate (12.3% + 1% MHST). High-income employees with significant RSU vesting, NQSO exercise, or large bonuses systematically end the year with insufficient withholding and owe a substantial Form 540 balance plus possibly a Form 5805 underpayment penalty.

Red flags during payroll review:

• Tech employees with annual gross compensation > $360,659 (10.3% bracket and up) receiving large RSU vests at 10.23% supplemental
• Executives with cash bonuses > $1,000,000 (MHST kicks in at 13.3% effective) withheld at 10.23%
• Annual W-2 Box 1 wages comparable to Box 16 (state wages) but CA withholding < 10.5% of Box 16 — likely under-withholding indicator

Mitigation:

• Employee files DE 4 requesting additional flat-dollar withholding per pay period
• Employer offers a "supplemental withholding election" allowing employees to elect a higher voluntary withholding on supplemental wages (some payroll platforms support this)
• Employee makes a Q4 estimated payment on Form 540-ES — refer to ca-540-es-estimated-tax skill for safe-harbor analysis

This is one of the most common findings in California tax-return preparation and a legitimate audit/inquiry point with EDD when the FTB cross-matches W-2 Box 17 to Form 540 line 71.

3.6 Wages Subject to California Withholding

California wages generally mirror federal Box 1 wages but with three notable differences:

1. HSA contributions — California does not conform to the federal exclusion. Employer and employee HSA contributions are taxable for CA PIT, SDI, SUI, and ETT and must be added back. CA wages = federal wages + HSA contributions.
2. Same-sex spouse health benefits — fully conformed since federal recognition, no longer an adjustment.
3. Domestic partner health benefits — California conforms to non-taxation for registered domestic partners; federal still taxes the imputed value. This makes CA wages LOWER than federal wages.
4. §125 cafeteria plan elections — generally conformed; no adjustment.

Verify the CA wage base independently — payroll software occasionally misses the HSA add-back, leading to under-withholding and an underreporting of SDI.

4. State Disability Insurance (SDI) and Paid Family Leave (PFL)

4.1 SDI — Cap Removal Under SB 951

Senate Bill 951 (Chapter 878, Statutes of 2022) eliminated the SDI taxable wage cap effective January 1, 2024, and the cap remains removed for 2025. This is the most consequential California payroll change in the last decade for high earners.

2025 SDI mechanics:

• Rate: 1.1% of gross wages
• Wage cap: None (uncapped)
• Paid by: Employee only (employer withholds and remits)
• Remitted on: Form DE 9 / DE 9C, alongside PIT
• Reported on: Form W-2 Box 14 ("CA SDI")

Prior to 2024, SDI had a wage cap ($153,164 in 2023 at a 0.9% rate, capping employee SDI at ~$1,378/year). With the cap removed and the rate at 1.1%, a Silicon Valley executive earning $5 million pays $55,000 in SDI for 2025 (vs ~$1,378 under pre-2024 rules). This is a 40× increase for top earners and is the largest CA payroll cost shift in a generation.

4.2 PFL — Bundled Into SDI

Paid Family Leave is administratively bundled into SDI. The same 1.1% withholding funds both the SDI benefit (own disability, including pregnancy) and the PFL benefit (bonding with new child, caring for seriously ill family member, qualifying military exigency).

2025 PFL benefit: Up to 8 weeks of partial wage replacement, capped at approximately $1,681 per week maximum (the benefit cap is set as a function of statewide average weekly wage; 60-70% wage replacement subject to the cap). SB 951 also increased the wage-replacement percentage for lower-wage workers up to 90% effective 2025.

The employer's payroll obligation is identical for SDI and PFL — there is no separate withholding. Employees apply for benefits directly through EDD; the employer's role at claim time is verifying employment and reporting the last day worked.

4.3 AUDIT FLASH POINT — SDI Removed-Cap Mid-Year Reconciliation

For payroll systems that were not properly reconfigured when the cap was removed, the typical failure mode is:

• Payroll software continued to apply the 2023 cap ($153,164) or some other stale cap into 2024 and 2025
• High earners were under-withheld for SDI
• The employer's DE 9/DE 9C for Q1-Q4 2024 understated SDI liability
• Form W-2 Box 14 reports an SDI figure smaller than 1.1% of Box 16 CA wages

Reconciliation procedure:

1. Pull Box 14 (CA SDI) and Box 16 (CA wages) from all 2024 and 2025 W-2s
2. Compute expected SDI = 1.1% × Box 16
3. Difference > $5 per employee is a flag
4. Employer must issue corrected W-2c, file amended DE 9X (DE 9 amended return), and collect the under-withheld SDI from the employee per Labor Code §221 (employer cannot absorb the SDI — it is the employee's tax)
5. EDD interest applies on the underpayment

This was the most common payroll-software error in 2024 and continues to surface in 2025 prior-period audits.

4.4 Voluntary Plan Alternative

Employers may opt out of state SDI and offer a Voluntary Plan (VP) approved by EDD under Unemployment Insurance Code §3251 et seq. The VP must provide benefits at least as generous as state SDI, must be approved by majority employee vote, and is subject to ongoing EDD oversight. Adoption is rare among SMBs because of administrative burden; large employers and certain industries use VPs.

---

5. State Unemployment Insurance (SUI)

5.1 Mechanics

SUI is paid entirely by the employer (no employee withholding) and is experience-rated based on the employer's history of unemployment-benefit charges.

2025 SUI structure:

• Wage base: $7,000 per employee per calendar year
• New employer rate: 3.4% for the first 2-3 calendar years (transferred to experience-rated schedule thereafter)
• Experience-rated range: 1.5% (best rating) to 6.2% (worst rating) in 2025
• Schedule: EDD publishes annual contribution rate schedules; the F+ schedule has been in effect because the UI trust fund is in deficit
• Maximum SUI per employee per year (new employer): $7,000 × 3.4% = $238
• Maximum SUI per employee per year (worst experience rating): $7,000 × 6.2% = $434

The employer receives a Notice of Contribution Rate (Form DE 2088) from EDD each December showing the rate for the following calendar year. Adjustments to the rate must be appealed within 60 days.

5.2 FUTA Credit Reduction Interaction

When the UI trust fund borrows from the federal government and fails to repay within statutory windows, California becomes a FUTA credit-reduction state. For 2023 and 2024 California was a credit-reduction state, and the trajectory suggests this may continue for 2025 (verify against the IRS / Department of Labor announcement in November 2025 for 2025 Form 940).

When CA is a credit-reduction state, the federal FUTA effective rate increases above the normal 0.6% by 0.3% per year of credit reduction. This is a federal cost increase (Form 940) but is a direct consequence of California UI policy and should be flagged to the employer during budgeting.

5.3 Voluntary UI Contribution

Under Unemployment Insurance Code §976.5, an employer may make a voluntary contribution by March 31 to "buy down" the experience rating for the next year. This is only beneficial when (a) the employer's experience rating is high and (b) the projected wages multiplied by the rate reduction exceed the voluntary contribution. Worth modeling for medium-sized employers (50+ employees) with deteriorating experience ratings.

---

6. Employment Training Tax (ETT)

ETT is the smallest of the four EDD taxes:

• Rate: 0.1% on the first $7,000 of wages per employee
• Max per employee per year: $7 (yes, seven dollars)
• Applies only to employers with a positive reserve account balance (i.e., the employer has paid more in SUI than has been charged in benefits). Negative-reserve employers are exempt from ETT.
• Purpose: Funds the Employment Training Panel (ETP) which subsidizes worker training programs

ETT is reported on the same Form DE 9 as SUI and PIT. New employers are positive-reserve by default and so pay ETT in their first years.

---

7. Quarterly Reporting — Form DE 9 and DE 9C

7.1 Form DE 9 — Quarterly Contribution Return and Report of Wages

Form DE 9 is the summary quarterly return. It reports:

• Total subject wages, PIT wages, UI taxable wages, and SDI taxable wages
• UI contributions due (employer)
• ETT due (employer)
• SDI withheld (employee)
• PIT withheld (employee)
• Total contributions and withholdings due
• Payments already made via DE 88 deposits
• Balance due or overpayment

7.2 Form DE 9C — Quarterly Contribution Return and Report of Wages (Continuation)

Form DE 9C is the detail schedule that accompanies DE 9. It reports for each employee:

• SSN, full legal name
• Total subject wages paid in the quarter
• PIT wages
• PIT withheld
• Pay period weeks (for SDI benefit-eligibility tracking)

The DE 9C is the EDD's primary cross-match source — the FTB uses it to verify Form 540 wage reporting and the EDD uses it to determine unemployment benefit eligibility. Errors on DE 9C are surfaced years later when an employee files an unemployment claim, so accuracy matters.

7.3 Due Dates

DE 9 and DE 9C are filed jointly each quarter:

Quarter	Period	Due Date
Q1	Jan-Mar	April 30
Q2	Apr-Jun	July 31
Q3	Jul-Sep	October 31
Q4	Oct-Dec	January 31 of following year

When the due date falls on a weekend or California state holiday, the next business day applies.

7.4 Filing Method

DE 9 and DE 9C must be filed electronically via e-Services for Business (EDD's online portal) for any employer required to file. Paper filings are accepted only with prior EDD waiver (rare).

7.5 Q4 DE 9 as Annual Reconciliation

The Q4 DE 9 doubles as the annual reconciliation — it must reconcile annual subject wages, PIT withheld, SDI withheld, UI taxable, etc., to the figures that will appear on Form W-2 Box 16 (state wages) and Box 17 (state withholding). Any discrepancy between cumulative DE 9C and W-2 totals is the most common EDD desk-audit trigger.

---

8. Deposit Cadence — DE 88 / E-Services

PIT withholding and SDI must be deposited on a cadence that matches the employer's federal deposit schedule and CA-specific PIT thresholds.

California PIT deposit thresholds (2025):

If PIT withheld in pay period is...	Deposit schedule
< $500 in a quarter	Deposit with quarterly DE 9 (no separate DE 88 needed)
≥ $500 in a quarter but federal schedule is monthly	Monthly deposit, due 15th of following month
Federal "next-day" deposit ($100,000+ in a single day)	Next business day
Federal semi-weekly	Semi-weekly (Wed-Fri payday → following Wednesday; Sat-Tue payday → following Friday)

The CA deposit is made via DE 88 coupon (electronic only — paper DE 88 was sunset) through e-Services for Business.

SUI and ETT are deposited with the quarterly DE 9 — not on the monthly/semi-weekly cadence. This often confuses payroll staff who expect SUI to follow federal FUTA cadence.

8.1 Penalties for Late Deposits

CA deposit penalties under R&TC §19170 et seq.:

• 15% of underpayment if not deposited timely (harsher than the federal 2%-15% graduated schedule)
• Plus interest at the FTB rate (3-5% annualized, adjusted semi-annually)
• Plus the 10% / 25% / 50% penalties for negligent or fraudulent failure under R&TC §19133

CA penalties are materially harsher than federal penalties; do not assume timely federal deposits satisfy CA.

9. CalSavers Retirement Mandate

9.1 Statutory Authority

CalSavers is governed by California Government Code §100000 et seq. and is administered by the CalSavers Retirement Savings Board. It is a Roth IRA-based payroll-deduction program for employees of employers that do not offer a qualified employer-sponsored retirement plan.

9.2 Mandate — 1+ Employee Threshold

Effective December 31, 2025, every California employer with one (1) or more employees that does NOT offer a qualified retirement plan (401(k), 403(b), SEP-IRA, SIMPLE IRA, etc.) must register with CalSavers and facilitate payroll deductions for employees who do not opt out.

Prior phased thresholds (now superseded):

Phase	Employees	Original Deadline
Phase 1	100+	June 30, 2020
Phase 2	50+	June 30, 2021
Phase 3	5+	June 30, 2022
Phase 4 (SB 1126, 2022)	1+	December 31, 2025

SB 1126 (Chapter 681, Statutes of 2022) expanded the mandate to all employers with at least one employee, effective December 31, 2025. Self-employed individuals without employees and sole proprietors who are the only person on payroll are exempt from the mandate but may still enroll voluntarily.

9.3 Employer Obligations

1. Register with CalSavers within the deadline (existing employer with 1-4 employees must register by Dec 31, 2025)
2. Submit employee census (name, DOB, SSN, contact info) within 30 days of hire
3. Facilitate payroll deductions at the default 5% rate (auto-escalating 1% per year to 8% max) unless the employee opts out or selects a different rate
4. Remit contributions to CalSavers via the portal each pay period
5. Do NOT make matching contributions (CalSavers is employee-only by design; employer matches are prohibited because that would convert it into an ERISA plan, which CalSavers is structured to avoid)
6. Do NOT provide investment advice (the employer's role is strictly clerical)

9.4 AUDIT FLASH POINT — CalSavers Mandate Enforcement

CalSavers enforces compliance through the Franchise Tax Board, with penalties under Government Code §100033:

• $250 per eligible employee if non-compliant 90+ days after notice
• Additional $500 per eligible employee if non-compliant 180+ days after notice
• Total potential penalty: $750 per employee

For a 5-employee shop that ignores the mandate, exposure is $3,750. For a 50-employee shop, $37,500. Enforcement letters began arriving in 2023 and have accelerated. The mandate is not optional and there is no de minimis exception below the 1+ threshold.

Compliance check during engagement:

1. Confirm whether employer offers a qualified plan (401(k), SEP, SIMPLE, defined benefit, etc.). If yes, file the CalSavers "Exemption" attestation in the portal.
2. If no qualified plan, confirm CalSavers registration and active facilitation.
3. Review payroll register for the CalSavers deduction line.
4. If neither plan nor CalSavers, the employer is non-compliant. Recommend immediate registration to mitigate penalty exposure.

10. Independent Contractor Classification — AB5 and the ABC Test

10.1 Statutory Authority

Labor Code §2775 et seq., enacted by Assembly Bill 5 (Chapter 296, Statutes of 2019) and amended by AB 2257 (Chapter 38, Statutes of 2020), codified the ABC test from the California Supreme Court's decision in Dynamex Operations West, Inc. v. Superior Court, 4 Cal.5th 903 (2018).

10.2 The ABC Test

A worker is presumed to be an employee unless the hiring entity proves ALL THREE of the following:

• (A) The worker is free from the control and direction of the hiring entity in connection with the performance of the work, both under the contract and in fact;
• (B) The worker performs work that is outside the usual course of the hiring entity's business;
• (C) The worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed.

If ANY prong fails, the worker is an employee for purposes of the Labor Code, Unemployment Insurance Code, and the wage orders.

The bar is materially higher than the federal common-law (Borello) test and substantially harder to satisfy than the IRS 20-factor test. A worker who is a federal 1099 contractor under federal common-law analysis can still fail the ABC test in California and be reclassified as an employee.

10.3 Statutory Exemptions

AB 5 / AB 2257 carve out specific occupations and business-to-business relationships that revert to the older Borello test (a multi-factor common-law analysis) rather than the ABC test. Major exemptions include:

• Licensed professionals: physicians, dentists, lawyers, architects, engineers, accountants (CPAs), private investigators, securities broker-dealers, investment advisers
• Direct sales salespersons
• Commercial fisherman
• Real estate licensees, repossession agents
• Construction subcontractors (with specific business-license and contract requirements)
• Referral agencies for licensed services (graphic design, photography, tutoring, etc., subject to detailed compliance criteria)
• Business-to-business contractors meeting all 12 criteria in §2776 (separate business location, separate business license, advertising, etc.)
• Freelance writers, photographers, content contributors meeting specific submission-count and contract conditions
• Single-engagement contractors meeting §2778 criteria

Practical impact on freelance software developers: Software development engagements are NOT among the statutory exemptions. A freelance software developer who works exclusively for one client over many months and whose work product is the client's core product (e.g., building the client's primary SaaS application) likely fails prong (B) and is an employee under the ABC test. A freelance developer building a marketing website for a non-tech company likely passes prong (B). The B2B exemption under §2776 may apply if all 12 criteria are met (S-corp or LLC structure, separate business license, separate workspace, multiple clients, etc.).

10.4 AUDIT FLASH POINT — AB5 Misclassification Disputes

Misclassification is the single highest-stakes California payroll exposure. Consequences:

• EDD reclassification of contractor payments as employee wages → back SUI, ETT, SDI, and PIT withholding for up to 3 years (sometimes longer with fraud allegations)
• Unpaid wages claims under Labor Code §1194 (minimum wage), §510 (overtime), §226.7 (meal/rest breaks), §226 (wage-statement violations) — recoverable for 3 years (4 with UCL claim)
• PAGA penalties under Labor Code §2698 et seq. — $100 per pay period per aggrieved employee, then $200 for subsequent violations, with 75% to LWDA and 25% to the employees, and a private right of action
• Workers' comp gap — the misclassified worker who is injured can claim against the employer despite no policy, exposing the employer to direct liability under Labor Code §3700
• Federal exposure — IRS §530 relief is unavailable if the misclassification is willful; Form SS-8 determination can also reclassify federally

Risk-management protocol:

1. Document the ABC analysis in writing for every 1099 contractor before engagement
2. Confirm the contractor has a separate business license, EIN, separate workspace, and other indicia of an independently established business
3. Use a written contract that recites the ABC factors and the contractor's independent-business status
4. Require the contractor to provide proof of business insurance, workers' comp coverage (if they have employees), and a current business license
5. If any prong is doubtful, treat the worker as an employee — the cost of reclassification dwarfs the cost of withholding

11. DE 542 — Independent Contractor Reporting

Under Unemployment Insurance Code §1088.8, an employer (referred to in the statute as a "service-recipient") must report any independent contractor to whom payments of $600 or more in a calendar year are made.

11.1 Mechanics

• Form: DE 542 (Report of Independent Contractor(s))
• Threshold: $600 in cumulative payments in a calendar year, OR a contract with a value of $600 or more (whichever occurs first)
• Due: Within 20 days of EITHER the contract being executed OR the $600 cumulative payment threshold being reached
• Information required: Service-recipient's name, address, FEIN, and CA employer account number; service-provider's name, SSN or FEIN, address; contract amount; contract start date; whether the contract is ongoing
• Filing method: Electronically via e-Services for Business; paper DE 542 still accepted via mail or fax

11.2 Purpose

DE 542 reporting feeds the California New Hire Reporting system, which the EDD shares with state agencies for child-support enforcement (Family Code §17506.5). It is NOT a tax document — the contractor pays their own taxes on Schedule C — but failure to file exposes the employer to penalties of $24 per failure, or $490 per failure for collusion to defeat child-support orders (Unemployment Insurance Code §1088.8(c)).

11.3 Interaction with Federal 1099-NEC

DE 542 is a California-only report, separate from federal Form 1099-NEC. Both are required for contractor payments of $600 or more (or $2,000 starting in 2026 per OBBBA — note federal threshold change but California has not conformed; CA DE 542 remains at $600). See us-1099-nec-issuance for federal mechanics.

---

12. Wage Statement Requirements — Labor Code §226

California has the most prescriptive itemized-pay-stub requirement in the United States. Labor Code §226(a) requires the employer to provide an itemized wage statement EITHER as a detachable part of the paycheck or as a separate document, containing nine specific items:

1. Gross wages earned
2. Total hours worked (for non-exempt employees only)
3. The number of piece-rate units earned and the applicable piece rate (if paid on piece rate)
4. All deductions (in detail, not aggregated)
5. Net wages earned
6. The inclusive dates of the period for which the employee is paid
7. The name of the employee and the last four digits of the SSN or an employee ID number
8. The name and address of the legal entity that is the employer
9. All applicable hourly rates in effect during the pay period and the corresponding number of hours worked at each rate

Additional itemization items required for piece-rate workers under §226.2, and for non-exempt salaried employees (regular rate of pay calculation for sick pay and overtime).

12.1 §226(e) Penalties

Failure to provide a compliant wage statement exposes the employer to:

• Actual damages or, if greater, a penalty of $50 for the initial violation per employee and $100 per subsequent violation per employee, per pay period, up to an aggregate of $4,000 per employee
• Costs and attorney's fees to a prevailing employee under §226(h)
• PAGA penalties under Labor Code §2699 ($100 / $200 per pay period per aggrieved employee, plus a 25% / 75% split with LWDA)

Common §226 failures:

• Missing the last four digits of the SSN (or using full SSN — equally a violation)
• Missing the legal entity name (e.g., showing the DBA but not the LLC)
• Aggregating deductions instead of itemizing
• Missing the pay-period dates
• Missing the regular rate of pay for non-exempt employees

The legal name on the wage statement must exactly match the legal name on the IRS EIN registration and the CA Secretary of State filing. A DBA-only wage statement is a §226 violation per Cicairos v. Summit Logistics, Inc., 133 Cal.App.4th 949 (2005) and its progeny.

13. Final Pay Rules and Waiting-Time Penalty

13.1 Timing of Final Wages

Labor Code §201-203 governs the timing of final wages:

• Involuntary termination (fired or laid off): Final wages, including all accrued unused vacation/PTO, are due IMMEDIATELY at the time of discharge (§201)
• Voluntary resignation with at least 72 hours' notice: Final wages due on the last day worked (§202)
• Voluntary resignation without 72 hours' notice: Final wages due within 72 hours of resignation (§202)

"Immediately" means at the moment of discharge — the employer must have the final paycheck (with all earned wages plus accrued PTO) ready to hand the employee when delivering the termination news. For practical scheduling, payroll teams often run a manual off-cycle check the day before.

13.2 PTO and Vacation Payout

California is a "use-it-or-don't-lose-it" state per Suastez v. Plastic Dress-Up Co., 31 Cal.3d 774 (1982). Accrued vacation/PTO is vested wages and must be paid out at the final rate of pay at termination. Cap on accrual is permitted (per Boothby v. Atlas Mechanical, Inc., 6 Cal.App.4th 1595 (1992)) but forfeiture of accrued PTO is not.

Sick leave under the Healthy Workplaces, Healthy Families Act of 2014 (Labor Code §245 et seq.) is NOT required to be paid out at termination, but if the employer maintains a combined PTO policy (vacation + sick in one bucket), the entire bucket is treated as vested and must be paid out.

13.3 AUDIT FLASH POINT — Waiting-Time Penalty Under §203

If the employer willfully fails to pay final wages on time, Labor Code §203 imposes a waiting-time penalty equal to one day of wages at the employee's regular rate for each day the wages remain unpaid, up to a maximum of 30 days.

Critical features:

• The penalty runs at the employee's full daily rate, not the unpaid balance. An employee earning $1,000/day with $50 of unpaid wages owed still triggers up to $30,000 in waiting-time penalties.
• "Willful" is broadly construed under Mamika v. Barca, 68 Cal.App.4th 487 (1998) — even a good-faith mistake can be deemed willful if there was no genuine legal dispute about the obligation to pay.
• Penalty is recoverable for up to 3 years under §203(b); the worker need not file a labor commissioner claim within 30 days.
• Section 203 penalties are NOT wages for tax purposes — they are penalties, reported on Form 1099-MISC Box 3 (Other Income), not Form W-2.

Mitigation: Process final paychecks for terminations BEFORE delivering the termination news. Confirm all PTO, commissions, bonuses earned (per Labor Code §200 definition of wages and Schachter v. Citigroup, Inc., 47 Cal.4th 610 (2009) on vested but unpaid bonuses), and any expense reimbursements (§2802) are included. Use direct deposit only if the employee has previously consented per Labor Code §213(d) — otherwise the final check must be a physical paycheck.

13.4 Tipped Workers Note (Brief)

California does NOT permit a tip credit under Labor Code §351. Tipped employees must be paid at least the full state minimum wage (or higher local minimum) plus tips. Tips are not wages for minimum-wage purposes but ARE wages for PIT/SDI withholding when reported (Form 4070 / Form 4137 federal mechanic; California conforms via DE 44 instructions). See worked example §15.2 for a retail-tip walkthrough.

14. Workers' Compensation and Local Taxes

14.1 Workers' Compensation — Mandatory

Labor Code §3700 makes workers' compensation insurance mandatory for every California employer of at least one employee. Coverage is via:

• A private workers' comp carrier (rates set by class code per the Workers' Compensation Insurance Rating Bureau (WCIRB))
• State Compensation Insurance Fund (SCIF) — the insurer of last resort
• Self-insurance (only for very large employers with regulatory approval)

Failure to carry workers' comp is a misdemeanor under §3700.5 with criminal penalties up to $10,000 and one year imprisonment, plus a $1,500 administrative penalty per employee per day uninsured, plus direct liability for any injured worker's benefits and damages.

Class-code rates vary enormously: a clerical employee (class 8810) might be 0.30% of payroll, a roofer (class 5552) might be 25%+ of payroll. WCIRB publishes the pure-premium rates; carriers apply experience modifications and underwriting discounts on top.

Practical: Verify the employer has an active workers' comp policy that covers all California employees, including remote employees working from home (California has expansive workers' comp coverage for telecommuting injuries).

14.2 Local Taxes — San Francisco

San Francisco imposes separate local business taxes that overlay state payroll obligations. The principal taxes are:

• Gross Receipts Tax (GRT) — Business and Tax Regulations Code Article 12-A-1; rates by industry sector, ranging roughly 0.075% to 1.0%+; applies to businesses with SF nexus and SF-attributable gross receipts above thresholds
• Homelessness Gross Receipts Tax — Article 28; surcharge on certain large businesses
• Commercial Rents Tax — Article 21
• Payroll Expense Tax — historically 0.38%; has been substantially phased out and replaced by GRT but residual obligations remain for certain large employers

SF payroll filing: Annual Business Registration Renewal and Statement of Information; quarterly estimated tax payments for businesses above thresholds; annual Business Tax Return (formerly Form P-2).

This skill REFERS OUT to SF Office of the Treasurer & Tax Collector and a credentialed SF tax practitioner for SF-specific compliance. The interactions between SF GRT, SF Payroll Expense Tax (residual), and state payroll are complex and beyond the Tier 2 scope.

14.3 Local Taxes — Los Angeles

LA City imposes a Business Tax (Los Angeles Municipal Code §21.00 et seq.) on businesses with LA city operations. Rates vary by classification and are filed annually with the Office of Finance. Many small businesses qualify for the LA small-business exemption (gross receipts under $100,000) but must still file a Statement of Information to claim it.

This skill REFERS OUT to LA Office of Finance and a credentialed LA tax practitioner. LA does not impose a separate payroll tax; the business tax is gross-receipts-based.

14.4 Other Local Payroll Surcharges

A handful of California cities have unique payroll surcharges:

• San Jose — Business tax; rate by employee count
• Oakland — Business license tax
• Berkeley — Business license tax with a payroll-based tier
• San Diego — Business tax certificate; nominal

Confirm the employer's city and check the city's business-license ordinance. Most are nominal but should not be ignored.

15. Worked Examples

15.1 Worked Example — SMB with 5 Employees (Tech Consulting, Non-Tipped)

Facts: Acme Consulting LLC (single-member LLC owned by founder, no S-corp election), based in Mountain View, CA. Five W-2 employees as of January 1, 2025:

Employee	Annual Salary	Filing Status	DE 4 Allowances
Ada (CEO)	$250,000	MFJ	2
Ben (Senior Dev)	$180,000	Single	1
Carol (Dev)	$120,000	HOH	2
Dan (Designer)	$90,000	Single	1
Eve (Office Mgr)	$60,000	MFJ	3

No bonuses, no equity. Acme offers a Solo 401(k) for the founder only — does NOT cover the W-2 employees. The W-2 employees have no employer-sponsored retirement plan.

California payroll tax computation for Q1 2025 (Jan-Mar):

Employee	Q1 Wages	PIT Withheld (est. Method B)	SDI 1.1%	SUI (3.4% × min($7,000, Q1 wages))	ETT 0.1% on same
Ada	$62,500	~$5,200	$687.50	$238 (cap hit)	$7
Ben	$45,000	~$3,400	$495.00	$238 (cap hit)	$7
Carol	$30,000	~$1,800	$330.00	$238 (cap hit)	$7
Dan	$22,500	~$1,400	$247.50	$238 (cap hit)	$7
Eve	$15,000	~$700	$165.00	$238 (cap hit)	$7
Total Q1	$175,000	$12,500	$1,925	$1,190	$35

(PIT amounts are approximate Method B estimates for illustration; actual amounts depend on pay-period bracketing.)

Q1 DE 9 total liability to EDD: $12,500 (PIT) + $1,925 (SDI, employee) + $1,190 (SUI, employer) + $35 (ETT, employer) = $15,650

Deposit cadence: Q1 PIT withholding is $12,500, which is materially above the $500 quarterly threshold. Acme's federal deposit schedule (assumed monthly based on prior-year aggregate < $50,000) translates to monthly CA deposits on the 15th of the following month:

• Jan PIT + SDI ≈ $4,800: deposit by Feb 15
• Feb PIT + SDI ≈ $4,800: deposit by Mar 15
• Mar PIT + SDI ≈ $4,800: deposit by Apr 15

SUI ($1,190) and ETT ($35) are remitted with the DE 9 by April 30 (not deposited monthly).

CalSavers compliance: Acme does NOT offer a qualified plan to its W-2 employees (the Solo 401(k) covers only the owner, who is not a W-2 employee here). Acme is therefore subject to the CalSavers mandate. Acme must register with CalSavers by December 31, 2025 (the 1+ employee deadline), submit the employee census, and facilitate payroll deductions at the default 5% rate. AUDIT FLASH POINT — failure exposes Acme to $750 × 5 = $3,750 in penalties.

Workers' comp: Acme must carry a workers' comp policy covering all five employees. Class code 8810 (clerical) and 8742 (outside sales / tech consulting at client sites) are likely applicable, with rates ~$0.30-$0.50 per $100 of payroll. Annual premium estimate on $700,000 annualized payroll: $2,100 - $3,500.

Annual reconciliation (Form W-2 Box 16/17): Each employee receives a Form W-2 in January 2026 showing CA wages in Box 16 and CA PIT withheld in Box 17. Box 14 shows SDI withheld. Acme files Form W-2 with the SSA by January 31, 2026 (federal) and the Q4 DE 9 by January 31, 2026 (CA) — the two filings must reconcile.

15.2 Worked Example — Retail with Tipped Employees

Facts: Bella's Bistro LLC, full-service restaurant in Sacramento, CA. Ten W-2 employees: 4 servers (tipped), 2 line cooks (non-tipped), 1 dishwasher (non-tipped), 2 bartenders (tipped), 1 manager (salaried exempt). The 2025 California minimum wage is $16.50/hour (statewide); Sacramento has no separate higher minimum wage (the city minimum aligns with state). Tipped employees are paid the full minimum wage in cash by the employer plus tips (no tip credit per Labor Code §351).

Server tip mechanics:

• Cash tips: Reported by the employee to the employer on Form 4070 (federal) or its equivalent by the 10th of the following month. Tips are subject to PIT, SDI, federal income tax, and FICA.
• Credit-card tips: Pooled by the restaurant and distributed to servers (and tip-pool participants per Labor Code §351; managers and owners cannot share in a mandatory tip pool). Reported via payroll.
• Service charges (mandatory gratuities of 18%+ on large parties): NOT tips — they are wages to the employee, subject to the employer's full payroll tax responsibility and minimum-wage compliance.

Worked Q1 2025 illustration — Server Sarah:

• Hourly rate: $16.50/hour
• Hours worked: 480 hours (Q1)
• Direct wages: $7,920
• Cash tips reported: $5,000
• Credit-card tips distributed: $4,000
• Total wages subject to CA PIT and SDI: $7,920 + $5,000 + $4,000 = $16,920

CA payroll on Sarah's Q1:

• PIT withheld (Method B, approximated, single, 1 allowance, quarterly): ~$340
• SDI 1.1% × $16,920 = $186.12 (employee)
• SUI 3.4% × min($7,000, $16,920) = $238 (employer, capped at $7,000 wage base)
• ETT 0.1% × $7,000 = $7 (employer)

Critical: Sarah's reported tips count toward the SUI wage base. Bella's SUI cost is therefore the maximum $238 for Sarah in Q1, even though her direct wages alone would not have hit the $7,000 cap until late Q2. This is a common reporting error — payroll software sometimes excludes tips from the SUI base, understating Bella's SUI liability for the lower-tipped employees.

Wage statement under §226: Sarah's pay stub must itemize:

• Gross direct wages
• Tips paid through payroll (credit-card pool)
• Cash tips reported (informational; usually shown as a memo line)
• All deductions (PIT, SDI, federal income tax, FICA Social Security, FICA Medicare, any union dues, etc.)
• Net pay
• Hours worked
• Pay period dates
• Sarah's name and last 4 of SSN
• Bella's Bistro LLC's full legal name and address
• Hourly rate ($16.50)

Failure to itemize any single item is a §226 violation per pay period, exposing Bella's to $50/$100 per pay period per employee.

Service Charges Note: If Bella's adds an automatic 20% service charge on parties of 6+, that 20% is NOT a tip — it's revenue to the restaurant, and any portion distributed to staff is straight wages. Wage statement must show it as a separate wage line.

15.3 Worked Example — Tech Company with Equity Grants (Founder + Engineering Hires)

Facts: Crescent Robotics Inc. (Delaware C-corp, registered to do business in California, sole headquarters in San Francisco). Founder Frank earns $250,000 W-2 salary; 8 engineering employees earn $200,000-$400,000 base; all employees receive Restricted Stock Unit (RSU) grants vesting quarterly. In Q1 2025:

• Frank vests $400,000 in RSUs (cliff-vest from a 2021 grant); FMV $400,000
• Eight engineers collectively vest $2,800,000 in RSUs
• Base salaries totaling $625,000 paid in Q1

California PIT withholding on RSU vests:

RSU vesting events generate W-2 ordinary income equal to the FMV of the shares at vest, less any amount paid by the employee (typically zero for RSUs). This income is supplemental wages for California withholding purposes — subject to the 10.23% flat supplemental rate unless aggregated with the regular paycheck.

For Frank's $400,000 vest:

• CA PIT supplemental withholding at 10.23%: $40,920
• SDI 1.1% × $400,000: $4,400 (no wage cap — full vest is SDI-taxable)
• Federal supplemental withholding at 22% (first $1M of supplemental in a calendar year): $88,000
• Federal Medicare 1.45% + Additional Medicare 0.9% (Frank's YTD > $200,000): $9,400
• Federal Social Security 6.2% — likely already capped from prior wages or this vest; if not, up to $176,100 base × 6.2% = up to $10,918

Frank's CA tax exposure at his 13.3% top marginal rate:

• True CA tax on the vest at the top bracket: $400,000 × 13.3% = $53,200 (assuming Frank's total income exceeds $1M, triggering MHST)
• CA PIT withheld at 10.23% supplemental: $40,920
• Under-withholding: $12,280 on this single vest

Across the year, if Frank has four such quarterly vests, the under-withholding compounds to ~$49,000 owed at year-end on Form 540. AUDIT FLASH POINT (§3.5 referenced) — Frank should file a DE 4 requesting additional fixed-dollar withholding per pay period, or make estimated payments via Form 540-ES (see ca-540-es-estimated-tax).

Aggregate Q1 CA payroll cost to Crescent:

Component	Amount
PIT withholding on base salaries (9 employees, mixed brackets)	~$70,000
PIT withholding on RSU vests ($3.2M × 10.23%)	$327,360
SDI on all wages ($625K base + $3.2M vest = $3.825M × 1.1%)	$42,075
SUI on first $7,000 per employee × 9 employees × 3.4% (assuming experience-rated; if new employer use 3.4%)	$2,142
ETT 0.1% × $7,000 × 9 employees	$63
Total Q1 CA EDD remittance	$441,640

The bulk is PIT withholding; SDI is the second-largest line item due to the uncapped wage base — $42K of SDI for a 9-person engineering team is a material expense category that did not exist before SB 951's cap removal.

Wage statement (§226): Each RSU vest event creates wages that must appear on the wage statement for the pay period in which the vest is settled. If Crescent uses a payroll integration with the equity-management platform (e.g., Carta), the vest amount and supplemental withholding lines must flow through to the pay stub. Otherwise, an off-cycle stub must be issued. Failure exposes Crescent to §226(e) penalties per vest event per employee.

§83(b) elections, ESPP disqualifying dispositions, NQSO exercises: All follow similar mechanics — supplemental withholding at 10.23% CA + 22% federal (or 37% on supplemental wages above $1M YTD federal). Refer to equity-comp specialist for §409A and §83(b) interactions.

CalSavers: Crescent offers a 401(k) plan to all employees with company match — Crescent is therefore EXEMPT from the CalSavers mandate but must still file the CalSavers exemption attestation in the portal (one-time, then maintained).

16. Cross-Skill Coordination

This skill outputs feed into:

• us-federal-payroll (separate skill, if loaded) — for Form 941, 940, W-2 federal mechanics
• ca-540-individual-return — Form 540 line 71 (CA withholding) is sourced from W-2 Box 17, which this skill governs at issuance
• ca-540-es-estimated-tax — employees with under-withheld supplemental wages (§3.5 flash point) feed into Q4 estimated-payment planning
• us-s-corp-election-decision — founders modeling S-corp election need accurate CA payroll cost estimates (SUI, ETT, SDI on the salary leg, CalSavers if no qualified plan) for the break-even analysis
• ca-llc-fee-and-tax — LLC owners who pay themselves as W-2 employees of their own S-corp run this skill; LLC owners who take guaranteed payments / draws do NOT (those are not wages and not subject to EDD payroll taxes)
• us-1099-nec-issuance — paired with §11 (DE 542) for any contractor payments

When called from us-ca-return-assembly, this skill produces the prior-year W-2 totals that flow into Form 540 line 71 and Schedule CA (540).

17. Conservative Defaults — Quick Reference

When facts are ambiguous, apply the conservative default and disclose:

Ambiguity	Conservative Default
Worker is contractor vs employee under ABC test	Employee unless all three prongs clearly pass
Tip amount disputed by employee	Use employee's reported figure (Form 4070 / payroll declaration)
SDI cap question	No cap (since 2024)
Supplemental withholding rate uncertainty	10.23% (consolidated 2025 rate)
CalSavers exemption claim where qualified plan coverage is fuzzy	Register with CalSavers; the exemption attestation requires affirmative qualified-plan status
Final-pay timing question	Same day for involuntary; same day or within 72 hours for voluntary
Wage-statement item missing	Reissue corrected statement and document the correction
Workers' comp coverage gap (e.g., remote employee in another state)	Confirm CA policy covers remote work; if remote employee is in another state, that state's WC may apply (refer-out)
AB5 exemption claim under §2776 B2B	All 12 criteria must demonstrably be met; partial satisfaction = ABC test applies
FUTA credit-reduction state status	Assume California IS a credit-reduction state for 2025 (verify in Nov 2025 IRS announcement)

19. Circular 230 Disclosure and Reviewer Responsibility

This skill is a content reference for credentialed payroll and tax professionals. It is NOT tax advice to the taxpayer. Under Treasury Department Circular 230 §10.33 and §10.37, any written advice based on this skill's output must be reviewed by a credentialed reviewer (Enrolled Agent, CPA, or attorney) — or for purely state-payroll matters, a CPP (Certified Payroll Professional) or experienced payroll practitioner with California-specific competence — before delivery to the client or filing with the EDD, FTB, or any other authority.

The skill is reviewer-oriented and assumes downstream reconciliation and self-checks per us-tax-workflow-base. Misapplication risk is high in three areas:

1. AB5 classification — the ABC test is unforgiving and litigation is active. When in doubt, treat as an employee.
2. SDI uncapped wage base — payroll system configuration drift continues to produce errors in 2025 prior-period audits.
3. CalSavers mandate — the December 31, 2025 1+ employee deadline arrives during the engagement window for many small businesses; non-registration is a $750/employee penalty.

A taxpayer or employer relying on this skill without credentialed review proceeds at their own risk. The skill is current as of November 15, 2025 and is subject to change with new EDD publications, FTB rate adjustments, court decisions affecting AB5, and statutory amendments.
