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 Pennsylvania (2026)

A bonus paid on a separate check in Pennsylvania has a flat 22% federal tax withheld (37% on cumulative supplemental wages over $1,000,000 in a year), 7.65% FICA, and Pennsylvania's flat 3.07% state income tax. 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
Pennsylvania state tax3.07% flat

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.

Pennsylvania Bonus Tax FAQ

How much are bonuses taxed in PA?

A bonus paid on a separate check in Pennsylvania has a flat 22% federal income tax withheld (37% on cumulative supplemental wages above $1,000,000 for the year), 6.2% Social Security, 1.45% Medicare, and Pennsylvania's flat 3.07% state income tax. Pennsylvania has no separate supplemental rate - the 3.07% flat rate applies to a bonus the same as to regular wages. Combined withholding is roughly 32-33% before any local Earned Income Tax.

What is the PA bonus tax rate for 2026?

Federal: flat 22% supplemental withholding. State: Pennsylvania's flat 3.07% Personal Income Tax. FICA: 7.65%. If you live or work in Philadelphia, the City Wage Tax (3.735% resident / 3.425% non-resident) also applies to the bonus - select it in the calculator.

Will I get some of the PA bonus tax back?

The 22% federal piece is withholding, not a final tax. Pennsylvania's 3.07% is close to a true flat tax so little changes there, but if 22% federal withholding is more than your actual federal marginal rate for the year, the difference comes back in your refund when you file.

Methodology & Source

Pennsylvania state tax figures sourced from Pennsylvania Department of Revenue (https://www.revenue.pa.gov/), citing 72 P.S. § 7302 — flat 3.07% Personal Income Tax rate, unchanged since 2004. 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). Pennsylvania's married-filing-jointly and head-of-household figures have been independently verified against the source above.

Local tax figures sourced from City of Philadelphia Department of Revenue — Wage Tax / Earnings Tax rates (https://www.phila.gov/services/payments-assistance-taxes/taxes/income-taxes/earnings-tax-employees/). Rate effective 2026-07-01 (part of a 5-year phased reduction plan); cross-checked against a second secondary source 2026-07-29.

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. Pennsylvania 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, FICA, and PA state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, local EIT, and other factors.
