Alabama Bonus Tax Calculator
Data compiled and maintained by Edmond Daher · Updated 2026-06-16
A Alabama bonus feels heavily taxed, but the missing chunk is withholding, not a bonus tax. Alabama adds a flat 5% on top of the 22% federal prepayment and FICA. Type in your salary and bonus below and the tool lines up today's withholding against your true tax, with the refund or balance due. Everything runs in your browser.
Short version: in Alabama, a bonus paid on its own is withheld at the flat federal 22%, 5% for Alabama, and 7.65% FICA. But that's only withholding. Your real bill is your marginal rate at filing; run the calculator to see the refund or shortfall.
Estimate only, not tax advice — terms.
What a $14,000 bonus really costs on a $215,000 Alabama income
Say you earn $215,000 in Alabama and your employer cuts a separate $14,000 bonus check:
- On the check: the employer holds back $3,080 for federal, $700 Alabama, and $329 for FICA — $4,109 in all (29.3% of the bonus), leaving about $9,891.
- The real bill: at filing the bonus is taxed roughly $4,950 in income tax (federal $4,250 + Alabama $700), with the identical $329 FICA on top.
- The gap: the 22% withheld falls short of your real rate, leaving about $1,170 to owe at filing. The $329 FICA doesn't move — that part is owed no matter what.

Alabama and Georgia, Tennessee and Mississippi: a bonus-withholding comparison
The same $10,000 bonus and $70,000 salary, in Alabama and its neighbors Georgia, Tennessee and Mississippi:
| State | Bonus method | State withheld | Total withheld |
|---|---|---|---|
| Alabama | flat 5% | $500 | $3,465 |
| Georgia | aggregate (~4.99%) | $499 | $3,464 |
| Tennessee | no state income tax | $0 | $2,965 |
| Mississippi | aggregate method | $400 | $3,365 |
Total combines the 22% federal, the state line, and FICA. Single-filer estimates — your real income tax settles when you file.
Why your Alabama bonus looks over-taxed — and mostly isn't
The 22% you see isn't a bonus levy; it's a withholding placeholder. Your bonus is ordinary income, and its real tax is whatever your marginal rate works out to across the brackets. Below a 22% real rate you get money back; above it, you settle the gap at filing. For the $14,000 bonus below, the flat withholding runs roughly $1,170 light, leaving that to owe. The one piece that never refunds is FICA (7.65%) — a genuine tax, not a prepayment.
Alabama bonus withholding across three bonus sizes
For a single filer on a $70,000 salary, here's the Alabama withholding at three bonus amounts:
| Bonus | Federal | Alabama | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $250 | $383 | $1,733 | 34.6% |
| $25,000 | $5,500 | $1,250 | $1,913 | $8,663 | 34.6% |
| $100,000 | $22,000 | $5,000 | $7,650 | $34,650 | 34.6% |
The % shifts as Social Security stops at the wage base; the income-tax portion still trues up when you file.
The three cuts on a Alabama bonus: federal, state, and FICA
Where the 22% comes from. Employers may withhold a flat 22% of a separately identified bonus for federal income tax (IRS Publication 15). A mandatory 37% hits supplemental pay beyond $1,000,000 a year; neither figure is a special "bonus" rate, both are withholding defaults.
Alabama keeps it simple: 5%. A separately paid bonus is subject to one flat state rate in Alabama, 5% (Alabama DOR employer withholding tables).
Set FICA aside as final. The 7.65% FICA bite is the tax itself — Social Security stops at the annual wage base, Medicare doesn't. Neither piece refunds at filing, so both columns of the tool show it unchanged; the income-tax withholding is the only part that trues up.

Alabama bonus tax FAQ
Why might I owe tax on my Alabama bonus at filing?
Because 22% is only a prepayment. If your true marginal rate is above 22% (high earners), the flat withholding falls short and you owe the rest; below 22%, you're over-withheld and get money back.
What is the Alabama bonus tax rate in 2026?
Alabama withholds 5% on a separately paid bonus, on top of the flat 22% federal rate (37% above $1,000,000/yr) and 7.65% FICA. That's withholding, not your final tax.
Does a bonus push my Alabama income into a higher bracket?
No. Brackets are marginal — only the dollars above each threshold are taxed higher. A bonus never re-taxes income you already earned.
Is there a special bonus tax rate in Alabama?
No. The 22% federal and the state supplemental rate are withholding defaults, not rates that apply only to bonuses. Your real tax is your ordinary marginal rate.
