Guides employers through the full North Dakota payroll compliance cycle: state income tax withholding (Form 307 quarterly returns, Form NDW-R annual reconciliation), new-hire reporting, and State Unemployment Insurance (SUI) wage reporting to Job Service North Dakota. Covers setup through year-end W-2 filing.
Before running payroll, the employer must obtain a North Dakota withholding account number from the ND Office of State Tax Commissioner (ND TAP portal) and register with Job Service North Dakota for State Unemployment Insurance (SUI). New-hire reporting must also be configured. This phase establishes the legal and administrative foundation for ND payroll compliance.
For each new employee, collect federal Form W-4 (North Dakota uses the federal W-4 for state withholding — there is no separate ND withholding certificate). Determine if the employee qualifies for exemption from ND withholding and, if so, obtain Form NDW-R (North Dakota Exemption from Withholding). Classify workers correctly as employees vs. independent contractors under ND law.
Run each payroll period, compute gross wages, apply ND income tax withholding using the ND income tax withholding tables (Publication NDW-T) based on the employee's W-4 elections, and calculate employer SUI contributions. Also compute federal payroll taxes (FICA, FUTA) alongside ND obligations. Deposit ND withheld taxes per the required schedule.
At the end of each calendar quarter, file North Dakota Withholding Return Form 307 with the ND Office of State Tax Commissioner reporting total wages paid and total ND income tax withheld. The quarterly due dates are April 30, July 31, October 31, and January 31. Form 307 is filed and paid electronically via ND TAP.
Each quarter, file the Quarterly Contribution and Wage Report with Job Service North Dakota reporting each employee's SUI-taxable wages and computing the employer's SUI contribution. The SUI taxable wage base is $43,800 per employee per year (2025). ND SUI rates vary by employer experience rating; new employers pay a standard rate. Reports are filed via the Job Service ND Employer Self Service portal.
At year-end, reconcile all four quarterly Form 307 filings against total ND wages and withholding for the calendar year. File Form 306 (Employer's Annual Withholding Reconciliation Return) with the ND Office of State Tax Commissioner by February 28, along with copies of all W-2s (or electronic W-2 file). Employees with NDW-R exemptions must renew them annually. Verify that W-2 Box 15–17 correctly reflects the ND withholding account number and ND taxes withheld.
