Default: worker classification
Treat worker as W-2 employee unless ABC test affirmatively fails (i.e., default to employee classification)
Default: STT applicability
Apply Statewide Transit Tax to all wages until exemption is documented
Default: transit district application
Apply TriMet/Lane/Cherriots to all hours worked inside the district unless employer has documented evidence of work performed entirely outside
Default: OR-W-4 missing
Use the standard OR-W-4 default (single, zero allowances) when no signed OR-W-4 is on file
Default: Paid Leave Oregon employee count
For Paid Leave Oregon employee count, count all employees nationwide, not just Oregon (per OED rule)
2025 Oregon PIT brackets (single filer)

Married filing jointly bracket doubling
For married filing jointly, double the bracket thresholds (top bracket begins at $250,000).
Oregon supplemental wage withholding rate (2025)
8.0%
OR-W-4
Oregon decoupled from the federal Form W-4 in 2020 when the IRS eliminated withholding allowances. Employers must obtain a Form OR-W-4 from every Oregon employee. The OR-W-4 still uses an allowances system and does not mirror the federal W-4 structure.
This skill is the authoritative Tier 2 content layer for Oregon employer payroll compliance for tax year 2025. It is consumed by upstream workflow skills (us-tax-workflow-base, us-federal-return-assembly) when an employer has Oregon-source wages, an Oregon resident employee, or any employee performing services within Oregon transit district boundaries.
or-corporate-activity-taxor-income-tax2025 Oregon PIT brackets (single filer)
| Taxable income (single) | Marginal rate |
|---|---|
| $0 – $4,300 | 4.75% |
| $4,301 – $10,750 | 6.75% |
| $10,751 – $125,000 | 8.75% |
| Over $125,000 | 9.90% |
The 9.9% top rate has been in place since 2013 and remains the third-highest top state PIT rate in the United States after California (13.3%) and Hawaii (11.0%).
This rate applies to bonuses, commissions, severance, equity vesting events, retroactive pay, and other supplemental wages identified under IRS Pub 15 (which Oregon incorporates by reference for definitional purposes but applies its own rate to).
Employers may use the supplemental flat rate or the aggregate method that combines the supplemental wage with the most recent regular pay period and applies the standard withholding tables. The flat method is strongly preferred for one-time large payments (bonuses, RSU vests) because the aggregate method can produce mechanical over-withholding when the supplemental payment is large relative to the regular paycheck.
AUDIT FLASH POINT: Form OQ filers commonly forget to attach Schedule STT or Schedule TM/LTD when the employer has Oregon wages but no employees in the transit district. The schedules must be filed with zeros rather than omitted — omission triggers a non-filer notice and a $50 penalty per schedule per quarter under ORS 314.400.
Oregon's 2025 taxable UI wage base is $54,300, the highest of any state. The wage base is set annually as 80% of the state average annual wage under ORS 657.435. For comparison:
Implications:
Oregon uses an experience-rated system with rates ranging from 0.0% to 5.4% in 2025. The new-employer rate for 2025 is 2.4%. Rates are assigned annually based on the employer's reserve ratio (cumulative contributions minus benefits charged, divided by average annual taxable payroll).
Schedule D applies for 2025 (Oregon has eight rate schedules A–H; D is the midpoint). The schedule is set by the OED based on the trust fund balance ratio.
AUDIT FLASH POINT: Employers commonly miscompute the taxable/excess split when an employee changes employers mid-year. The $54,300 wage base is per-employer per-year, not per-employee per-year across employers. A new hire whose YTD wages with the prior employer already exceeded $54,300 still owes UI tax on the first $54,300 paid by the new employer.
The Statewide Transit Tax (STT), enacted under HB 2017 (2017) and codified at ORS 320.550, is a 0.1% payroll tax on:
AUDIT FLASH POINT: Out-of-state employers with even one Oregon-resident remote worker frequently miss STT registration entirely. The 0.1% feels trivial per paycheck (e.g., $1 on a $1,000 weekly check) but compounded across years with no wage cap, an out-of-state employer with five Oregon remote employees earning $100,000 each owes $500/year STT — small in dollars but a 100% audit certainty given OED's data-share with DOR. The non-filing penalty under ORS 314.400 is the larger exposure.
AUDIT FLASH POINT: The STT applies to non-resident remote workers physically in Oregon. A consultant living in Vancouver, WA who crosses the river to work at a Portland client site has STT-covered wages for those days. The day-by-day allocation must be tracked.
The TriMet (Tri-County Metropolitan Transportation District of Oregon) employer payroll tax applies to wages paid for services performed within the TriMet district, which encompasses most of Multnomah County, the urban portions of Washington County, and the urban portions of Clackamas County.
The TriMet rate is statutorily increased by 0.0001 (1 basis point) per year through 2026 under ORS 267.385, then capped.
The Lane Transit District employer payroll tax applies to wages paid for services performed within the LTD boundary, which covers most of Lane County including Eugene, Springfield, and surrounding communities.
Several smaller cities and special districts impose narrow employer payroll taxes (typically 0.5%–0.7%) for local transit. These are jurisdiction-by-jurisdiction and require boundary verification using the DOR's transit district lookup tool.
AUDIT FLASH POINT: The single most common Oregon payroll audit finding is misallocation between TriMet, Lane, and "no transit district." Employers often default all Oregon wages to TriMet because Portland is the largest metro, or default everything to "no district" because the employer is headquartered outside Oregon. Both are wrong. Each employee's work-location geocoding must be documented and refreshed annually, and remote-work reallocations during 2020–2024 created retroactive exposure that the OED began aggressively auditing in 2024.
AUDIT FLASH POINT: The employer/employee 40/60 split is the most commonly mis-coded line item in Oregon payroll. Many payroll providers default to 50/50 or to "employer pays all" which produces an over-payment by the employer and an under-withholding from the employee — and creates a constructive bonus to the employee that should have been included in federal Box 1 wages. The 40/60 must be coded explicitly.
AUDIT FLASH POINT: Employers using the small-employer (<25) exemption often miscount by limiting to Oregon employees. OED counts nationwide. Misclassification as small triggers a back-assessment of employer contributions plus interest from program inception.
AUDIT FLASH POINT: WBF is computed per-hour, not per-dollar. A common mistake is to apply a 0.0066% rate to wages, which dramatically under-reports. The correct base is hours worked × $0.0066.
AUDIT FLASH POINT: Software developers, designers, and other "professional" contractors frequently fail Prong B because they only have one client and do not advertise. Even with a Form 1099-NEC issued, OED can reclassify and impose retroactive UI, STT, transit, and Paid Leave taxes plus penalties under ORS 657.471.

Default rule when no OR-W-4 is on file
withhold as single with zero allowances. This is the most conservative default and the explicit DOR rule.
OR-W-4 retention
retain for at least four years following the last calendar year the certificate was in effect. Submit to DOR only when requested or when the employee claims more than 10 allowances (mandatory submission trigger under OAR 150-316-0290).OAR 150-316-0290
Form OQ
Form OQ is Oregon's unified quarterly return that consolidates four employer obligations into a single filing: 1. Oregon income tax withholding 2. Oregon UI tax (Schedule B) 3. Statewide Transit Tax (Schedule STT) 4. TriMet or Lane Transit tax (Schedule TM or LTD) if applicable
Form OQ due dates and e-filing
Due dates: April 30, July 31, October 31, January 31. Electronic filing via Frances Online (Oregon Frances Online portal, which replaced OTTER) is mandatory for employers with 250+ W-2s and strongly encouraged otherwise.
Form OR-WR Annual Withholding Reconciliation
Form OR-WR (Annual Withholding Reconciliation) is due January 31 of the following year and reconciles the four quarterly OQs to the W-2/W-3 filed with DOR.

Cherriots administration
Unlike TriMet and LTD, the Cherriots tax is administered locally rather than through Form OQ; the employer registers with and remits to Cherriots directly.
Boundary determination steps
Determining whether a wage is "subject" to TriMet or LTD requires: 1. Geocoding the work location (not the employee's residence) 2. Cross-referencing the geocoded coordinates against the official transit district map (published annually by each district) 3. For remote workers, applying the principal-place-of-services test under OAR 150-267-0030: the location where the employee performs the majority of work in the quarterOAR 150-267-0030
Paid Leave Oregon program overview
Paid Leave Oregon, enacted under HB 2005 (2019) and effective for benefits on September 3, 2023, provides up to 12 weeks of paid leave per benefit year (14 weeks for pregnancy-related conditions, with potential combined leave up to 16 weeks) for: - Family leave (bonding with a new child, caring for a family member with a serious health condition) - Medical leave (the employee's own serious health condition) - Safe leave (issues stemming from domestic violence, sexual assault, harassment, or stalking) Benefits are wage-replacement up to a maximum weekly benefit indexed to 120% of the state average weekly wage (approximately $1,568.60 per week in 2025).
Paid Leave Oregon combined contribution rate (2025)
1.0%
25+ employees nationwide split
For employers with 25 or more employees nationwide: Employer share: 40% of the total (0.4% of wages); Employee share: 60% of the total (0.6% of wages, withheld from paychecks)
Fewer than 25 employees nationwide
For employers with fewer than 25 employees nationwide: Employer share: $0 (exempt from employer portion); Employee share: 0.6% of wages (still withheld); Small employers may opt in to employer-portion participation to qualify for grants
25-employee count basis
The 25-employee count is a nationwide headcount, not Oregon-only. A California company with 30 employees and one Oregon remote worker is a "25+" employer for Paid Leave Oregon purposes.
Paid Leave Oregon contribution wage base cap
$176,100 for 2025 (Social Security wage base)
Wages above SS cap
Wages above the SS cap are not subject to Paid Leave contributions.
Paid Leave Oregon filing schedule
Paid Leave Oregon contributions are reported on Schedule P of Form OQ quarterly. The schedule is filed with both employer and employee shares combined and remitted with Form OQ.
Equivalent private plans
Employers may apply to OED for approval of an equivalent private plan that provides benefits and protections at least equal to the state plan. Approved equivalent plans exempt the employer (and its employees) from state contributions.

Oregon independent contractor ABC test
Oregon does not have a single statutory ABC test analog to California AB5. However, ORS 670.600 (the "independent contractor" definition for OED and DOR purposes) operates as a de-facto ABC test and has been strengthened by case law and by 2020+ administrative guidance. A worker is an independent contractor only if all of the following are true: A. The worker is free from direction and control over the means and manner of providing services, subject only to the right of the contracting person to specify the desired results. B. The worker is customarily engaged in an independently established business of the same nature as the services contracted for. Three of the following five factors must be met: 1. Maintains a business location separate from the contracting person 2. Bears the risk of loss 3. Provides contracted services for two or more different customers within a 12-month period, or routinely engages in business advertising or solicitation 4. Makes a significant investment in the business through tools, equipment, or premises 5. Has the authority to hire and fire employees to perform the contracted services C. The worker is licensed under ORS 671 or 701 if such license is required for the services performed. Failure on any of A, B, or C reclassifies the worker as a W-2 employee for Oregon withholding, UI, STT, transit district, Paid Leave, and WBF purposes.ORS 670.600
Final pay rule under ORS 652.140
Under ORS 652.140: - Employer-initiated termination (firing/layoff): all wages due by the end of the next business day after termination - Employee-initiated termination (quit) with 48+ hours notice: all wages due on the last day worked - Employee-initiated termination without 48 hours notice: all wages due within five business days or the next regular payday, whichever is earlierORS 652.140
Penalty wages under ORS 652.150
Violation triggers penalty wages under ORS 652.150 equal to the employee's regular daily wage rate for each day the wages remain unpaid, up to 30 days. Penalty wages are owed even if the underpayment is minor.ORS 652.150
FMLA and Paid Leave Oregon concurrency
Paid Leave Oregon runs concurrently with federal FMLA leave when both apply. An employer covered by both must coordinate the leave designation; treating them as sequential (rather than concurrent) is a violation under both OED rule and DOL guidance.
Oregon Pay Equity Act requirements
The Oregon Pay Equity Act (ORS 652.220) prohibits pay discrimination based on protected class and requires equal pay for work of "comparable character." For payroll purposes: - Salary history inquiries are prohibited - Pay decisions must be defensible against an "affirmative defense" requiring a documented equal-pay analysis within the prior three years - Posting of salary ranges in job postings is required under separate amendments Payroll system implications: maintain documented job-evaluation factors and ensure compensation changes carry justification metadata.ORS 652.220
