North Dakota Employer Payroll Compliance Skill

Scope. This skill covers North Dakota employer payroll obligations for a business with employees performing services in North Dakota during tax year 2025 (returns and deposits filed 2025–2026). Covers: ND personal income tax (PIT) withholding under N.D.C.C. § 57-38-59; Form 306 quarterly withholding returns; Form 307 annual W-2/1099 transmittal; Form NDW-M (state W-4); Form NDW-R (MN/MT reciprocity exemption); ND State Unemployment Tax (SUTA) under Job Service North Dakota; new-hire reporting to the ND Child Support Division; and the WSI workers' compensation monopoly. Federal payroll (Form 941, Form 940, FICA, FUTA, federal W-4, federal new-hire reporting, federal Form W-2 filing with SSA) is out of scope — see the federal payroll skills.

Quality tier. Tier 2 content skill. AI-drafted; awaiting verifier sign-off. All employer-side outputs must be reviewed by a qualified ND payroll professional before filing or remitting. [VERIFY:] markers flag figures that must be re-confirmed against current ND Tax Commissioner / Job Service ND / WSI publications for the applicable period.

Section 3: North Dakota personal income tax withholding

3.1 Statutory basis

N.D.C.C. § 57-38-59 requires every employer maintaining an office or transacting business within ND, and making payment of any wages subject to ND income tax, to deduct and withhold the tax. The withholding obligation parallels the federal obligation under IRC § 3402 and applies to wages of:

• ND residents, regardless of where services are performed; and
• Nonresidents, to the extent services are performed within ND (subject to the MN and MT reciprocity exemptions below).

3.2 HB 1158 of 2023 — phase-down context

In April 2023 the 68th Legislative Assembly enacted HB 1158, the largest individual income tax relief package in ND history. The Act:

• collapsed the prior five-bracket structure to three brackets;
• created a 0% bottom bracket that exempts the first tranche of taxable income for every filer; and
• set the remaining two positive brackets at 1.95% and 2.50%.

The bracket thresholds are indexed annually. Practitioners must re-verify the bracket thresholds for each tax year against the Tax Commissioner's withholding booklet because (a) the indexing adjustments are non-trivial and (b) the legislature has shown a pattern (cf. NC SB 105 and GA HB 111) of making mid-cycle adjustments where revenue triggers are met.

3.3 TY 2025 brackets — single filer (withholding booklet)

[VERIFY: 2025 ND Withholding Booklet, percentage method, Table 1A]

Taxable wages over	But not over	Withhold
$0	$47,150	$0
$47,150	$238,200	1.95% of excess over $47,150
$238,200	—	$3,725.48 + 2.50% of excess over $238,200

3.4 TY 2025 brackets — married filing jointly (withholding booklet)

[VERIFY: 2025 ND Withholding Booklet, percentage method, Table 1B]

Taxable wages over	But not over	Withhold
$0	$78,775	$0
$78,775	$289,975	1.95% of excess over $78,775
$289,975	—	$4,118.40 + 2.50% of excess over $289,975

3.5 Supplemental wage rate

Supplemental wages (bonuses, commissions, severance, back pay, retroactive pay, awards) paid separately from regular wages, or separately identified on the pay stub, may be withheld at a flat 1.5% for 2025. Alternatively, the employer may use the aggregate method (combine with regular wages, compute withholding on the total, subtract regular-wage withholding).

3.6 Pay-period frequency

The Tax Commissioner publishes percentage method tables and wage-bracket tables for the following frequencies: weekly, biweekly, semimonthly, monthly, quarterly, semiannual, annual, daily/miscellaneous. The percentage method is mandatory for software-driven payroll; wage-bracket tables remain authoritative for manual payroll under $1 million in wages.

---

Section 4: Form NDW-M and choice of method

4.1 What NDW-M is

Form NDW-M ("Withholding Allowance Certificate for Pension or Annuity Payments and Employee's State of Residence") is the ND state equivalent of federal Form W-4. Effective from 2020 onward, ND defaults to using the federal Form W-4 for state withholding purposes (no separate state W-4 required for the vast majority of employees). NDW-M is used only for:

• pension and annuity payees electing ND withholding; and
• employees who want different ND elections from their federal W-4 elections (rare).

4.2 Method election

Employers may use either:

• Percentage method — required for computer payroll. Uses the bracket tables in §§ 3.3–3.4.
• Wage bracket method — published tables in the 2025 Withholding Booklet, acceptable for manual payroll only.

4.3 Employee with no W-4 on file

Where an employee has not furnished a federal Form W-4 to the employer, the employer must withhold ND tax as if the employee had checked Single with no adjustments on the W-4 (consistent with the IRS § 3402 default).

---

Section 5: Minnesota–North Dakota reciprocity — AUDIT FLASH POINT

5.1 Statutory and historical basis

ND and MN have maintained an income tax reciprocity arrangement since 1957, suspended in tax years 2003 and 2004, and re-negotiated effective January 1, 2005. The agreement is supported on the ND side by N.D.C.C. § 57-38-59.1 and on the MN side by Minn. Stat. § 290.081. Both states issue parallel guidance each filing season confirming the agreement remains in force.

Under the agreement, wage and salary income paid for personal services performed in ND by an MN resident is taxable only in MN; and vice versa for ND residents working in MN. The agreement does not cover:

• self-employment, partnership, S-corporation, or rental income;
• gambling winnings;
• income from a closely-held business that is not wage compensation; or
• lottery/contest winnings.

5.2 Mechanics — Form NDW-R

To stop ND withholding on a qualifying MN resident's wages, the employee must give the employer a completed Form NDW-R ("Reciprocity Exemption from Withholding for Qualifying Minnesota and Montana Residents Working in North Dakota").

Step	Action	Deadline
1	Employee completes NDW-R, swearing under penalty of perjury that they are a permanent MN (or MT) resident	By Feb 28 each year, or within 30 days of starting work / changing residence
2	Employer stops ND withholding from the next available payroll	Effective immediately on receipt
3	Employer mails the Tax Commissioner's copy of NDW-R to the ND Office of State Tax Commissioner	By March 31 each year
4	Employee renews NDW-R every year	Annually — prior-year form does not roll over

The employer must withhold Minnesota income tax instead (under MN Stat. § 290.92), which requires the employer to register for an MN withholding account if not already registered.

5.3 What happens if the NDW-R is missing — the audit flash point

If a qualifying MN resident's employer fails to obtain a current-year NDW-R, ND requires the employer to withhold ND tax from the employee's wages notwithstanding the underlying reciprocity. The employee's recourse is then to file Form ND-EZ at year-end claiming a full refund of the ND tax withheld — a 6-to-12-month cash-flow hit for the employee, and a common source of complaints against employers.

Common employer errors:

1. Treating the NDW-R as evergreen. It is not. Each calendar year requires a fresh NDW-R.
2. Failing to mail the Tax Commissioner copy by March 31. This is a filing obligation on the employer, not the employee. Penalty exposure under N.D.C.C. § 57-38-45.
3. Forgetting to register for MN withholding. The employer must withhold MN tax. Failure to do so creates an MN delinquent-employer status.
4. Continuing the exemption after the employee moves to ND. If the employee's residence changes mid-year, the employer must restart ND withholding immediately.
5. Applying the exemption to self-employed contractors. NDW-R covers wages only.

5.4 Who can use NDW-R

Eligibility requires the employee to be:

• a permanent resident of MN or MT for the entire tax year;
• maintain a permanent home in MN or MT throughout the year; and
• not maintain a permanent home in ND.

A taxpayer who maintains an apartment in Fargo for convenience while keeping a permanent home in Moorhead, MN, generally qualifies. A taxpayer who has moved their permanent residence to Fargo does not, regardless of where their driver's license is issued.

---

Section 6: Montana–North Dakota reciprocity

The ND-MT reciprocity agreement has been in force since 1976. The mechanics mirror the MN agreement:

• A qualifying MT resident files Form NDW-R with their ND employer.
• The employer stops ND withholding and starts MT withholding.
• The agreement covers wage and salary income only.
• The same Feb 28 / March 31 deadlines apply.

The MT side of the agreement is administered by the MT Department of Revenue under § 15-30-2110, MCA. MT residents working in ND are not common in practice — the population centers are remote from the MT border — but oilfield and pipeline workers in Williston/Bakken can hit this regularly.

---

Section 7: Quarterly Form 306 reporting

7.1 Form and due dates

Form 306 ("Income Tax Withholding Return") is the quarterly remittance/reconciliation return. Due dates:

Quarter	Period	Due date
Q1	January 1 – March 31	April 30
Q2	April 1 – June 30	July 31
Q3	July 1 – September 30	October 31
Q4	October 1 – December 31	January 31

When the due date falls on a Saturday, Sunday, or legal holiday, the next business day is the deadline.

7.2 Mandatory electronic filing

An employer whose ND withholding totaled $1,000 or more for the prior calendar year must file Form 306 electronically through the ND Taxpayer Access Point (TAP) at https://apps.nd.gov/tax/tap. Payment is via ACH Debit (initiated within TAP) or ACH Credit (initiated through the employer's bank). Paper Form 306 is available only for employers below the $1,000 threshold.

7.3 No deposit-frequency election

Unlike federal Form 941 (which is paired with semiweekly or monthly deposit schedules), ND does not require interim deposits. The full quarterly liability is paid with Form 306 on the quarter-end deadline. Practitioners migrating from CA, NY, or IL frequently over-engineer this — there is no ND analog to those interim deposit schedules.

7.4 Penalties

• Late filing: 5% of tax due, minimum $5, per N.D.C.C. § 57-38-45.
• Late payment: 5% of tax due, plus interest at the rate set annually by the Tax Commissioner (12% per annum simple for 2025 [VERIFY: 2025 interest rate posting]).
• Failure to file electronically when required: $500 per return, per N.D.C.C. § 57-01-02.1.
• Failure to deposit by EFT when required to deposit electronically: up to 5% of underpayment.

7.5 Zero returns

A registered employer who paid no ND wages for the quarter must still file a zero Form 306. Failure to file the zero return triggers the late-filing penalty floor.

---

Section 8: Annual reconciliation — Form 307 + W-2/1099

8.1 Form 307

Form 307 ("Transmittal of Wage and Tax Statement") is the annual employer reconciliation, due January 31 of the year following the calendar year. Form 307 is the ND analog to federal Form W-3.

It is filed electronically through TAP, together with copies of:

• all Forms W-2 issued to employees with ND wages or ND withholding; and
• all Forms 1099 (1099-NEC, 1099-MISC, 1099-R) that reported ND withholding.

8.2 W-2 filing

For TY 2025, employers must file copies of all W-2s that report:

• wages paid to ND residents (regardless of withholding); or
• wages paid for services performed in ND; or
• ND tax withheld.

Electronic filing is required for employers issuing 10 or more W-2s (aligning ND with the federal 10-form threshold under T.D. 9972). The TAP file specification follows the SSA EFW2 format with the ND state record extension.

8.3 1099-NEC filing

Forms 1099-NEC reporting nonemployee compensation with ND withholding (rare because ND does not require 1099 backup withholding the way some states do) must be filed with the Tax Commissioner by January 31. 1099-NEC without ND withholding need not be filed separately with ND — the federal Combined Federal/State Filing (CF/SF) program covers this.

8.4 Reconciliation tie-out

The sum of ND withholding reported on the four quarterly Forms 306 must equal the sum of ND tax withheld shown on the W-2/1099 forms transmitted with Form 307. Mismatches trigger a Tax Commissioner desk audit.

Section 9: ND State Unemployment Tax (SUTA)

9.1 Administration

Job Service North Dakota (JSND) administers the state unemployment insurance program under N.D.C.C. Chapter 52-04. Employers register and file through the UI EASY portal at https://www.jobsnd.com.

9.2 Wage base

Year	ND SUTA taxable wage base
2024	$43,800
2025	$45,100
2026	[VERIFY: not yet published as of 2026-05-28]

The wage base is recalculated each year as 70% of the statewide average annual wage. ND's wage base is consistently among the five highest in the US.

9.3 Rate structure (2025)

[VERIFY: 2025 Tax Rate Schedules from JSND]

• Positive-balance experience rates: 0.08% – 1.85% (Schedule 1).
• Negative-balance rates: up to ~9.97%.
• New employer (non-construction): 1.02% on rate Schedule [VERIFY].
• New employer (construction): 6.09% [VERIFY].
• Rates are issued annually in November/December for the following calendar year via SFN 41216.

A new employer remains on the new-employer rate until they have been liable for ND UI for the period ending on the prior June 30 (i.e., typically 3 full fiscal years of experience).

9.4 Quarterly contribution and wage report

Form SFN 41263 is the quarterly Employer's Contribution and Wage Report, due the last day of the month following quarter end (same calendar as Form 306). Mandatory electronic filing via UI EASY for all employers as of 2018. Includes:

• gross wages by employee;
• excess wages (above the taxable wage base year-to-date);
• contribution computation; and
• SOC occupational code reporting (for ETA data) [VERIFY: still required 2025].

9.5 Penalties

• Late report: $25 minimum, plus interest at 1.5% per month on unpaid contributions.
• Failure to file: rate increased by 1% under N.D.C.C. § 52-04-05.
• Misclassification of workers (treating employees as 1099 contractors): exposes employer to back contributions, penalty, and interest, and JSND applies the multi-factor "right to control" test more aggressively than many states.

---

Section 10: New-hire reporting

10.1 Federal basis

PRWORA § 453A (codified at 42 U.S.C. § 653a) requires every employer to report each newly hired employee to the designated state agency within 20 days of the date of hire (or, for employers reporting magnetically/ electronically, in two monthly transmissions not less than 12 and not more than 16 days apart).

10.2 ND-specific mechanics

• Reporting agency: North Dakota Child Support Division, Department of Health and Human Services.
• Method: Electronic upload via https://www.nd.gov/childsupport, fax, or paper W-4 with the employer's FEIN added.
• Trigger: Each newly hired or re-hired employee (re-hired = returning after a separation of 60+ days). Independent contractors paid $2,500 or more are also reportable in ND under § 14-09-09.5.
• Data required: Employee name, address, SSN, DOB, date of hire; employer name, address, FEIN.

10.3 Multistate-employer election

An employer with employees in two or more states may designate a single state for all its new-hire reporting under 42 U.S.C. § 653a(b)(1)(B). The designation is filed with the federal Office of Child Support Enforcement (form found at acf.hhs.gov). An employer headquartered in MN with workers in both MN and ND may elect to report all hires to MN — but the election must be filed; absent the election, the employer must report ND hires to ND.

---

Section 11: Workforce Safety & Insurance (WSI)

11.1 The monopoly — frequently missed by out-of-state employers

ND is one of only four US states (with OH, WA, and WY) operating a monopolistic state workers' compensation fund. WSI is the exclusive provider of workers' compensation coverage in ND. A private workers' compensation insurance policy purchased from a national carrier (Travelers, Liberty Mutual, The Hartford, etc.) does not satisfy the ND coverage requirement, and the employer is treated as uninsured.

Statutory basis: N.D.C.C. Title 65.

11.2 Mandatory coverage

Coverage is mandatory for every employer with one or more employees, including:

• full-time, part-time, seasonal, and temporary employees;
• corporate officers (unless they file Form C-3 elective exclusion);
• employees of out-of-state employers performing any work in ND (a Texas-based pipeline employer sending a crew to the Bakken triggers WSI coverage from day 1).

Exemptions are narrow (limited to certain agricultural employers, real estate brokers paid solely on commission, and specific independent contractors meeting the 9-factor test).

11.3 Enforcement

WSI conducts compliance audits using NDDOR and JSND data feeds. Penalties for uninsured operation under N.D.C.C. § 65-04-33:

• Triple premium plus penalty (typically the prior 3 years' would-be premium × 3);
• Personal liability of corporate officers under N.D.C.C. § 65-09-02;
• Potential stop-work order shutting down the ND operation; and
• Treble damages in any employee injury suit.

11.4 Premium computation

Premiums are based on classification code, payroll, and experience modifier. Reporting is annual via the WSI online portal. New employers receive an "industry average" rate for their NAICS code; experience modification kicks in after 3 years of claims history.

11.5 Practical reminder for the Fargo audit

If a Texas, Florida, or even South Dakota employer expands to a Fargo office and ports its existing national workers' comp policy, the ND coverage is invalid from day 1. The employer must apply to WSI before the first day of ND employment. This is the single most common compliance failure for employers expanding into ND.

---

Section 12: Final pay, garnishment, child support

12.1 Final paycheck

Under N.D.C.C. § 34-14-03:

• Involuntary termination: final pay due on the next regular payday (the employee may demand earlier by certified mail, in which case the employer must pay within 15 days).
• Voluntary resignation: final pay due on the next regular payday.
• Accrued, unused PTO is payable only to the extent the employer's written policy or contract so provides — ND default rule is no PTO payout obligation absent agreement.

12.2 Wage garnishment

ND follows federal Consumer Credit Protection Act (CCPA) limits: 25% of disposable earnings or 30 × federal minimum wage, whichever is less. Child support withholding orders take priority over creditor garnishments and may take up to 50–65% of disposable income under 15 U.S.C. § 1673(b)(2).

12.3 Child support withholding

Employers receive an Income Withholding for Support (IWO) from the ND CSD or another state's agency. Withholding must begin no later than the first pay period after 14 days from the date the IWO was mailed. Remittance to the ND State Disbursement Unit within 7 business days of withholding.

Section 13: Tier 1 deterministic rules vs Tier 2 judgment rules

13.1 Tier 1 (deterministic — apply mechanically)

Rule ID	Statement
T1-ND-PAY-01	If employer's prior-year withholding ≥ $1,000, Form 306 must be filed electronically through TAP.
T1-ND-PAY-02	Form 306 quarterly due dates are 4/30, 7/31, 10/31, 1/31.
T1-ND-PAY-03	Form 307 annual reconciliation is due January 31.
T1-ND-PAY-04	An MN or MT resident must file NDW-R annually to exempt wages from ND withholding.
T1-ND-PAY-05	Employer must mail the Tax Commissioner copy of NDW-R by March 31.
T1-ND-PAY-06	2025 ND SUTA taxable wage base is $45,100.
T1-ND-PAY-07	2025 ND supplemental wage rate is 1.5%.
T1-ND-PAY-08	New-hire reports are due to the ND CSD within 20 days of hire.
T1-ND-PAY-09	ND workers' comp must be obtained from WSI — private coverage is invalid.
T1-ND-PAY-10	Final pay is due on the next regular payday.
T1-ND-PAY-11	An employer issuing 10+ W-2s must file them electronically with ND via TAP.

13.2 Tier 2 (judgment — surface to verifier)

Rule ID	Statement
T2-ND-PAY-01	Whether a commuter qualifies as a "permanent MN resident" under NDW-R when they maintain a Fargo apartment for the work week is a domicile-law determination.
T2-ND-PAY-02	Whether a corporate officer should file the WSI Form C-3 elective exclusion depends on closely-held-business risk tolerance.
T2-ND-PAY-03	Whether the multistate-employer new-hire election should be made to ND, MN, or HQ-state is an administrative-burden tradeoff.
T2-ND-PAY-04	Whether a worker is an employee or 1099 contractor for SUTA purposes — JSND applies a 9-factor right-to-control test that overlaps but differs from the IRS 20-factor test.
T2-ND-PAY-05	Whether to use the percentage method or wage bracket method when both produce different cents of withholding for low-wage employees.

Section 14: Worked examples

Example 1 — Standard ND-resident employee, biweekly $2,500, single, no NDW-R

Facts. Anna lives in Bismarck, ND. Biweekly gross wages = $2,500. Federal W-4 = single, no adjustments. No 401(k), no Section 125.

Step 1 — Annualize. $2,500 × 26 = $65,000 annual wages.

Step 2 — Apply 2025 single bracket table [VERIFY: 2025 booklet exact threshold]. Assume bottom-bracket cutoff = $47,150 single.

Taxable above cutoff: $65,000 - $47,150 = $17,850
Annual ND tax: $17,850 × 1.95% = $348.08
Per pay period: $348.08 / 26 = $13.39

Step 3 — Round. Round per the percentage method instruction (to the nearest whole dollar): $13.00 withheld per biweekly pay.

Step 4 — Form 306, Q1. Anna's six pays in Q1 → $13 × 6 = $78 ND tax remitted with Form 306 by April 30. (Aggregated with all other employees.)

Example 2 — Minnesota commuter with NDW-R on file

Facts. Bjorn lives in Moorhead, MN, and commutes daily to a software job in Fargo, ND. Biweekly gross wages = $3,200. Filed NDW-R on his first day of work, dated February 1, 2025.

Step 1 — Verify NDW-R. Employer confirms:

• Permanent address in MN: yes (verified driver's license + lease).
• Form signed and dated within 30 days of start: yes.
• Calendar-year specific: yes (2025).

Step 2 — ND withholding. Zero ND tax withheld on Bjorn's wages for the entire 2025 calendar year.

Step 3 — MN withholding. Employer registers for an MN withholding account and withholds MN tax under MN Stat. § 290.92 using Form W-4MN.

Step 4 — Employer's March 31 obligation. Employer mails the Tax Commissioner copy of Bjorn's NDW-R to the ND Office of State Tax Commissioner by March 31, 2025.

Step 5 — Renewal. A fresh NDW-R is required on or before February 28, 2026 for the 2026 calendar year. The employer should diary this in December 2025.

Failure mode. If Bjorn forgets to renew in February 2026 and the employer does not collect a 2026 NDW-R, the employer must withhold ND tax from his 2026 wages starting January 1, 2026 (or, in practice, the first payroll after the Feb 28 default deadline). Bjorn then files Form ND-EZ in 2027 to claim the ND withholding back as a refund — a real cash flow hit, and the source of frequent payroll complaints.

Example 3 — High-income ND-resident at the top bracket

Facts. Carla is a Bismarck-based oilfield engineer earning $325,000 annual salary, paid semimonthly ($13,541.67 gross per pay). Federal W-4 = single, no adjustments. She receives a $50,000 year-end bonus.

Regular wage withholding per pay period

Annualize: $13,541.67 × 24 = $325,000. Apply 2025 single percentage table [VERIFY exact thresholds]:

First $47,150 → 0%
$47,150 to $238,200 → 1.95% × $191,050 = $3,725.48
Above $238,200 → 2.50% × ($325,000 - $238,200) = 2.50% × $86,800 = $2,170.00
Annual ND tax = $5,895.48
Per pay (÷24) = $245.65

Round → $246 ND withheld per semimonthly pay.

Year-end bonus — supplemental rate

Paid on a separate check identified as a bonus:

$50,000 × 1.5% = $750 ND tax withheld

The 1.5% supplemental rate is below Carla's marginal rate of 2.50%, so she will under-withhold on the bonus by approximately ($50,000 × 1.00%) = $500. The employer is not at fault — the supplemental rate is a statutory safe harbor — but Carla should be advised to make an ND estimated payment on Form 540-ES [VERIFY: ND uses Form ND-1ES for estimates] to avoid a balance due in April 2026.
