Alabama Bonus Tax Calculator

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 Alabama (2026)

A bonus paid on a separate check in Alabama has a flat 22% federal tax withheld (37% on cumulative supplemental wages over $1,000,000 in a year), 7.65% FICA, and Alabama state income tax at your marginal rate. 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

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.

⚠️ Alabama's married-filing-jointly and head-of-household state brackets have not yet been independently verified against the primary source above — this calculator uses Alabama's single-filer brackets as an estimate when those statuses are selected.

⚠️ Some Alabama cities and counties levy a local occupational tax, typically 0.5%-2% of wages. Birmingham, Bessemer, Gadsden, Attalla, Opelika, and Auburn are now computed via the selector above; dozens of smaller Alabama municipalities with their own occupational tax are still not covered.

Dependents can also reduce federal withholding via the W-4. Check Alabama Department of Revenue's married-filing-jointly tables for a precise figure.

Does this calculator include Alabama local or city income tax?

Some Alabama cities and counties (e.g. Birmingham, Bessemer) levy a local occupational tax, typically 0.5%-2% of wages, not computed here.

Methodology & Source

Alabama state tax figures sourced from Alabama Department of Revenue (https://www.revenue.alabama.gov/), citing Ala. Code § 40-18-5 — 3-bracket schedule; § 40-18-15 permits deducting federal income tax paid. 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). Alabama's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.

Local tax figures sourced from City occupational/license tax ordinances (Birmingham, Bessemer, Gadsden, Attalla, Opelika, Auburn). Rates cross-checked against two independent secondary sources 2026-07-29 (city-tax aggregator listings and payroll-guide summaries); Gadsden's own city revenue page does not publish the numeric rate online, so it relies on secondary sourcing only — flagged here rather than silently treated as equally verified. Alabama has dozens of smaller municipalities with occupational tax not listed below; select "Other" for those.

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. Alabama 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 AL state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors. Alabama's standard deduction is income-graduated ($2,000-$4,000 for single filers depending on AGI); this estimate uses a flat $3,000 approximation.
