How Alabama State Taxes Work
Alabama uses a three-bracket system with rates of 2, 4 and 5 percent, unchanged since 1935. The brackets are so narrow that nearly all of a normal income lands in the 5 percent band, so the subtractions that happen first are what really set your bill. You get a standard deduction that starts at $3,000 for single filers and $8,500 for married couples filing jointly in 2026, phasing down to $2,500 and $5,000 once income passes $35,500. Personal exemptions add $1,500 per single filer or $3,000 per couple, plus $1,000 for each dependent.
Then comes the part most calculators miss: you subtract the federal income tax you pay from your Alabama taxable income before the state rates apply. On a $55,000 single income, that removes about $4,420 from Alabama's reach in 2026 and drops the effective state rate to roughly 4.2 percent. It's why your AL state tax line looks smaller than the 5 percent headline rate suggests, and why two neighbors with identical salaries in Alabama and Georgia don't pay the same state tax.
What Gets Taken Out of Your Alabama Paycheck
Every Alabama paycheck carries federal income tax, Social Security at 6.2 percent and Medicare at 1.45 percent, the same FICA math as everywhere else, with Social Security capped at the $184,500 wage base for 2026. Alabama state tax rides on top at its effective 3.5 to 4.2 percent for most middle incomes. If your employer offers health insurance or a 401(k), those pre-tax deductions come out before taxes are figured, which lowers every line that follows.
One thing plenty of pages get wrong: Alabama has no city income tax in the usual sense, but in 2026 more than two dozen municipalities charge an occupational tax on wages earned inside their limits. Birmingham, Bessemer, Fairfield, Auburn and Opelika take 1 percent of gross pay; Gadsden and Tuskegee take 2 percent. Work in Huntsville, Mobile, Montgomery or Tuscaloosa and there's no city line at all. It follows where you work, not where you live, so a Hoover resident commuting into Birmingham still pays it.
Hourly and Salary Paychecks Use the Same Math
An hourly wage just gets annualized first. At $20 an hour, 40 hours a week is $800, about $41,600 a year, taxed exactly like salary income under 2026 rules. Overtime past 40 hours pays time and a half ($30 an hour in that example), and every extra dollar runs through the same tax lines. A single filer at that hourly rate with biweekly checks and a Birmingham job nets about $1,288 per check. Tips, bonuses and commissions count as wages too, so hourly workers in restaurants or retail can estimate take-home pay the same way.
Overtime in 2026: your overtime is withheld like normal wages all year. Alabama's full exemption ended June 30, 2025. What's left are deductions you claim at filing: up to $1,000 of overtime premium on your Alabama return (Act 2026-604, through 2028) and up to $12,500 ($25,000 joint) on your federal return.
