Alabama lets employers withhold a flat 5% on bonuses and other supplemental wages. They can also add the bonus to a regular paycheck and use the regular formula, which can come out lower because Alabama subtracts your federal withholding before applying its 2% to 5% brackets.

Is a Bonus Taxed Higher in Alabama?

No. A bonus is ordinary wage income. It only looks heavily taxed because the employer withholds at flat rates instead of your personal rate. When you file your 2026 return, the bonus is added to your salary and taxed at the same federal brackets and Alabama rates as the rest of your pay.

The federal 22% is a good fit for people in the 22% bracket. If your income keeps you in the 10% or 12% bracket, the flat rate over-withholds and the extra comes back as a refund. If the bonus pushes you into the 24%, 32% or higher bracket, 22% is too little and you will owe the difference in April. The calculator compares both numbers for your salary.

Social Security and Medicare work differently: they are a flat 7.65% on wages and are not settled at filing. The one exception is Social Security on wages above $184,500 in 2026. Once your salary plus bonus passes that cap, the 6.2% stops. If two employers both withheld it, you claim the excess back on your return.
