Estimate take-home pay on a bonus, using the federal flat-rate supplemental withholding method

Estimate only — not tax advice. Federal tax on the bonus uses the flat 22% supplemental withholding rate (37% on cumulative supplemental wages over $1,000,000/year) — the alternative "aggregate method" some employers use instead is not modeled. FICA and any state SDI/PFL are computed as the difference between your regular income with and without the bonus added, so the Social Security wage cap applies correctly. State tax on the bonus is a marginal-bracket estimate, not necessarily any special state supplemental rate. See methodology below for source and last-verified date.

How Bonuses Are Taxed in Texas (2026)

A bonus paid on a separate check in Texas has a flat 22% federal tax withheld (37% on cumulative supplemental wages over $1,000,000 in a year), 7.65% FICA, and no Texas state income tax on the bonus. Withholding is not a higher tax rate — it is just how much your employer holds back up front; your actual tax on the bonus is settled when you file, and any over-withholding comes back as refund.

ComponentRate on the bonus
Federal income tax (supplemental, percentage method)22% flat  ·  37% above $1,000,000/yr
Social Security6.2% (up to $184,500 of total wages)
Medicare1.45%  ·  +0.9% above $200,000
Texas state taxNone — no state income tax

Some employers instead use the aggregate method — adding the bonus to your regular paycheck and withholding as if that were every check — which can withhold more or less than the flat 22%. The calculator above uses the flat-rate (percentage) method.

Methodology & Source

Texas state tax figures sourced from Texas Comptroller of Public Accounts (https://comptroller.texas.gov/), citing Tex. Const. art. VIII, § 24 (voter-approved 2019 ban on a state personal income tax). Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Texas's married-filing-jointly and head-of-household figures have been independently verified against the source above.

Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled. Texas publishes no separate supplemental withholding rate, so the calculator estimates the state tax on the bonus from your marginal bracket.

This is an estimate based on standard single-filer federal and FICA calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions (401k, health insurance), and other factors.
