Bonus inputs

Use gross-to-net for a planned bonus or net-to-gross when a take-home amount was promised. This tool is limited to one-time or nonperiodic taxable cash bonuses; use a full paycheck calculation for regular or periodic wages, commissions, and overtime. Calculations run in your browser; this block does not submit the values you enter.

Gross bonus amount Enter the taxable bonus to be paid.

Federal withholding method

Payment presentation Federal flat withholding can apply to a separately identified amount when eligible. Utah does not publish a separate bonus-rate instruction in Publication 14; select the Utah payroll-period treatment actually used for the payment independently of the federal method.

Regular wages had federal income tax withheld

The optional 22% federal flat method generally depends on regular wages having had income tax withheld in the current or prior year.

Pay frequency

Social Security wages before this bonus Enter same-employer 2026 Social Security wages immediately before the bonus, including regular wages on the same payment. Used for the $184,500 wage-base check.

Medicare wages before this bonus Enter same-employer 2026 Medicare wages immediately before the bonus, including regular wages on the same payment. Used for the employer's $200,000 Additional Medicare withholding threshold.

YTD supplemental wages before bonus Include supplemental wages paid in 2026 by this employer and businesses under common control for the $1 million federal test.

Extra federal withholding per regular check

Extra federal withholding in aggregate mode Applied only to the aggregate-method estimate. IRS prescribed 22% and 37% supplemental rates cannot be increased by an employee request.

Actual federal withholding already taken from reference wages Aggregate mode subtracts federal income tax already withheld from the regular and earlier same-period reference wages. Leave blank to model that amount from the W-4 inputs above; if the federal eligibility box is clear, a blank baseline defaults to $0.

Utah income-tax withholding settings

Utah formula period Publication 14 revised the schedules effective June 1, 2026. Select by the beginning date of the payroll period, not the payment date alone.

Utah payroll-period treatment Utah Pub. 14 has no separate supplemental-wage section. Use the first option when payroll associates the bonus with the selected regular period; use Schedule 8 only when payroll classifies the standalone check as daily/miscellaneous.

Utah withholding profile The 20-day exclusion has residency and occupation limits. Transportation and military-spouse exclusions require the Utah-only notation described in Publication 14.

Utah income-tax withholding applies

Profile presets update this control. Clear it only when current documentation and the employee's facts support an exclusion.

Utah filing status from federal W-4 Publication 14 says to use the Single column for head-of-household filers.

Utah-taxable bonus percentage Utah residents are generally subject on wages inside and outside Utah. For nonresidents, enter the supportable Utah-service allocation.

Regular Utah-taxable wages for the selected period Used only for the regular-period difference estimate. Enter wages already classified as Utah taxable for that period.

Other-state withholding attributable to this bonus For a Utah resident working in another taxing state, Publication 14 permits Utah withholding to be reduced by required withholding for that state. Enter only the bonus-attributable amount; the reduction cannot make Utah withholding negative.

Utah publishes payroll-period schedules, not a special bonus rate. The regular-period option calculates the published schedule on regular Utah wages plus the allocated bonus and subtracts the regular-wage result. The standalone option applies published Schedule 8 to the allocated bonus. The official schedules round their calculation lines to whole dollars, which this estimator reproduces.

Employer cost estimate settings

YTD Utah UI wages before bonus Used only for the employer-side Utah unemployment wage-base estimate.

Utah UI wage base Utah Workforce Services lists a $50,700 taxable wage base for 2026.

Utah UI employer rate The 0.10% example is the 2026 minimum, not a default for every employer. Use the assigned rate; 2026 rates range from 0.10% to 7.10%, plus a possible 1% delinquency surcharge.

Utah UI-taxable bonus percentage Bonuses are UI wages. This changes employer cost only; Utah UI cannot be deducted from employee wages.

YTD FUTA wages before bonus Used only for the employer-side $7,000 FUTA wage-base estimate.

Estimated net FUTA rate Default assumes the full 5.4% state credit. Use the employer's actual net FUTA rate and any applicable credit-reduction treatment.

What this calculator includes

Federal supplemental methods

Model the optional 22% method, the mandatory 37% rate only above $1 million of calendar-year supplemental wages, and the aggregate method using the 2026 Publication 15-T tables.

Both 2026 Utah formula periods

Apply the 4.50% schedules before June 1 or the 4.45% schedules beginning June 1, including filing status, pay frequency, the 1.3% credit reduction, and official whole-dollar rounding.

Employee and employer costs separated

Keep Utah income-tax withholding and employee FICA in take-home while Utah UI, FUTA, and employer FICA remain employer-side costs.

This is a 2026 withholding estimate for an ordinary taxable cash bonus paid to a W-2 employee. Pretax benefits, retirement deferrals, wage exclusions, garnishments, prior same-period supplemental payments, multiple employers, predecessor/common-paymaster rules, nonresident sourcing, other-state adjustments, and payroll-provider treatment can change the actual paycheck. Utah Publication 14 does not publish a separate bonus-rate instruction, so confirm whether payroll uses the regular-period calculation or Schedule 8. Withholding is not final income-tax liability.

Utah bonus withholding FAQ

Does Utah publish a flat bonus withholding rate?

No separate supplemental-wage method appears in the current Publication 14. Utah publishes schedules for regular payroll periods and a daily/miscellaneous Schedule 8. This calculator makes the payroll-period treatment explicit instead of presenting 4.45% as a universal bonus method.

Why are there two 2026 formula periods?

The 4.45% schedules apply to payroll periods beginning on or after June 1, 2026. Earlier 2026 periods use the prior 4.50% schedules. The base allowance and wage threshold also changed.

How does the regular-period estimate work?

The calculator applies the selected Publication 14 schedule to regular Utah wages plus the allocated bonus, then subtracts the schedule result on regular wages alone. This isolates the bonus increment without inventing a state flat method.

When should Schedule 8 be selected?

Select it only when payroll treats the standalone payment as a daily or miscellaneous payroll period. Publication 14 labels Schedule 8 that way but does not state that every separate bonus must use it.

Can a Utah resident receive an other-state reduction?

Publication 14 says Utah withholding for a resident's services in another taxing state may be reduced by withholding required by that state. Enter only the amount attributable to this bonus and confirm the employer's multistate method.

Are there Utah withholding exclusions?

Yes, but each is conditional. Publication 14 covers a valid exemption certificate, certain nonresidents working 20 days or less, interstate transportation workers, and qualifying nonresident military spouses.

Does Utah unemployment tax reduce the bonus?

No. Utah UI is paid entirely by the employer. Bonuses are reportable wages, the 2026 wage base is $50,700, and the employer must enter its assigned rate.

Can this calculator gross up a promised net bonus?

Yes. Net-to-gross mode solves in cents across the federal methods, FICA thresholds, the selected Utah formula, other-state reduction, and employer wage caps.

Disclaimer: This 2026 Utah bonus tax calculator provides an estimate of net pay and tax withholdings based on federal supplemental guidelines and Utah State Tax Commission Publication 14 rules, including the June 1 formula update, but it does not constitute formal legal, financial, or tax advice. Actual paycheck results may vary due to individual W-4 elections, pre-tax deductions, multi-state tax allocations, local requirements, or employer-specific payroll configurations, meaning users should verify all final calculations and official state and federal schedules with a qualified payroll professional before processing actual payroll.
