Estimate a Tennessee employee's net bonus, compare 2026 federal supplemental-wage methods, test Social Security and Medicare thresholds, and gross up a promised take-home amount.
Model the optional 22% method, the mandatory 37% rate only on supplemental wages above $1 million, and the aggregate method using 2026 Publication 15-T.
Show the Tennessee employee income-tax line explicitly at $0 while still calculating federal income tax, Social Security, Medicare, and Additional Medicare withholding.
Test Social Security, Additional Medicare, FUTA, and Tennessee unemployment insurance against distinct year-to-date wage inputs so employer costs never reduce employee take-home pay.
This is a 2026 withholding estimate for an ordinary taxable cash bonus paid to a W-2 employee. It assumes the entered bonus is subject to federal income tax, Social Security, and Medicare. Pretax benefits, retirement deferrals, garnishments, fringe-benefit valuation, special wage exclusions, railroad rules, nonresident-alien adjustments, multistate withholding, same-period earlier supplemental payments, and payroll-provider rounding can change the actual paycheck.
No. Tennessee has no state income tax on earned income and no wage-withholding requirement, so the Tennessee employee withholding line is $0.
It is optional for an eligible separately paid or separately identified supplemental amount when federal income tax was withheld from regular wages in the current or immediately preceding year.
The aggregate method calculates federal withholding on regular wages plus the bonus for one payroll period, then subtracts withholding on regular wages alone using the employee's Form W-4 settings.
Only the portion that takes 2026 supplemental wages above $1 million is subject to mandatory 37% withholding. The threshold includes common-control businesses.
No. Tennessee unemployment insurance is employer-funded. The employer-cost estimate uses an editable assigned rate and the official 2026 $7,000 taxable wage base.
No. It is a withholding method, not final tax liability. The employee's federal return reconciles total annual income, deductions, credits, and withholding.
Social Security stops at its annual wage base, while Medicare has no cap and Additional Medicare withholding begins when this employer pays more than $200,000.
Yes. Net-to-gross mode solves the gross amount under the selected federal method plus Social Security, Medicare, and Additional Medicare withholding.
Rates and formulas are based on primary official material checked on July 17, 2026. Recheck year-specific wage bases, assigned unemployment rates, and federal updates before later-year payroll.

Disclaimer: This calculator provides a non-binding withholding tax estimate for W-2 employee bonus payments in Tennessee, utilizing the 2026 federal Publication 15-T tables alongside standard FICA and state unemployment regulations. Because Tennessee does not levy a state personal income tax on regular earned wages, the state-level employee income tax withholding line is fixed at $0. This output is intended solely for general financial forecasting and does not constitute formal legal, accounting, or professional payroll advice. Actual paycheck values may vary depending on voluntary retirement deferrals, pretax medical premiums, local wage allocations for out-of-state remote workers, garnishments, employer-specific UI tax brackets, or provider-specific rounding algorithms. Employers must verify all ultimate payroll configurations with a certified tax professional before distribution.
