North Dakota Bonus Pay Tax Calculator
Estimate a North Dakota employee's net bonus with the state's official 1.5% supplemental option or aggregate method, federal withholding, FICA, employer costs, reciprocity profiles, gross-up planning, and a $1,000 child-support reporting reminder.
Bonus inputs
Use gross-to-net for a planned taxable cash bonus or net-to-gross for a promised take-home amount. Federal and North Dakota methods are selected independently.
North Dakota withholding settings
North Dakota's 1.5% is a withholding option, not final tax liability. Separately paid or separately identified supplemental wages may use 1.5% or the aggregate difference. An unseparated same-check payment uses ordinary withholding on the combined wages.
Federal Form W-4 settings
Federal aggregate estimates use the 2026 Publication 15-T automated percentage method for a Form W-4 from 2020 or later. Review older federal W-4s, nonresident-alien adjustments, exempt status, and special wage facts separately.
North Dakota employer-cost settings
North Dakota UI, WSI, FUTA, and employer FICA are employer costs and never reduce employee take-home. The calculator models no general North Dakota local wage-income tax or state paid-leave payroll deduction.
What this calculator includes
Use 1.5% for eligible separately paid or separately identified supplemental wages, or calculate the ordinary withholding difference on regular plus supplemental wages.
Model eligible 22% and aggregate federal methods, 37% above $1 million, Social Security through $184,500, Medicare, and Additional Medicare above $200,000.
North Dakota income withholding and FICA reduce take-home. UI, optional WSI, FUTA, and employer FICA stay outside employee deductions.
This 2026 estimate covers a taxable cash bonus to a W-2 employee. It does not determine exemption eligibility, multistate sourcing, workers' compensation classification, child-support withholding, or final income-tax liability. Use current employee forms, notices, and production payroll records.
North Dakota bonus withholding FAQ
Does North Dakota have a flat bonus option?
Yes. Separately paid or separately identified supplemental wages may use 1.5%. It is a withholding option, not an estimate of final tax liability.
What is the other state method?
Add the supplemental wages to the relevant regular wages, calculate ordinary North Dakota withholding on the combined amount, and subtract regular-wage withholding.
What if the bonus is not separately identified?
Calculate withholding on the combined payment as ordinary wages. The calculator allocates the incremental difference to the bonus for planning.
Does North Dakota use Form W-4?
Yes. The 2026 booklet provides separate methods for Forms W-4 from 2020 or later and valid pre-2020 forms; this calculator supports both state percentage methods.
Who can claim reciprocity?
Qualifying Minnesota and Montana residents working in North Dakota may be exempt after furnishing a valid Form NDW-R. The form must be renewed as required.
Does North Dakota unemployment reduce take-home?
No. UI is employer-only. The 2026 taxable wage base is $46,600 and the employer's assigned rate notice controls.
Why is there a child-support reminder?
For an employee subject to an income withholding order, North Dakota requires notice before a qualifying lump-sum payment of $1,000 or more. Actual support withholding is not calculated here.
Can the calculator gross up a promised net bonus?
Yes. Net-to-gross mode solves against the selected federal and North Dakota methods plus employee FICA.

Primary official material was checked on July 30, 2026. Recheck the employee's Form W-4 and any NDW-R or NDW-M, payment presentation, sourcing, employer UI and WSI notices, wage bases, child-support order, and federal updates before production payroll. The TimeTrex North Dakota page is a convenience CTA, not formula authority.
