Alabama paycheck guide
How Alabama calculates income tax in 2026
Alabama has three brackets for single filers: 2% on the first $500 of taxable income, 4% on the next $2,500, and 5% on everything above $3,000. Married couples filing jointly get brackets twice as wide, with 5% starting at $6,000. Because the top rate begins so low, Alabama behaves almost like a flat 5% tax for anyone with a full-time paycheck.
Three subtractions come before the brackets. The personal exemption is $1,500 for a single filer and $3,000 for a married couple. The standard deduction runs on a sliding scale tied to Alabama adjusted gross income: it tops out at $3,000 for a single filer and $8,500 on a joint return, and it shrinks as income rises. Our single-filer examples follow the chart: $2,775 at a $30,000 salary and the $2,500 floor from $50,000 up. Heads of household start higher, at $5,200.
The third subtraction is the one that sets Alabama apart: you deduct the federal income tax you owe for the year. That ties the state bill to the federal one. Anything that lowers your federal tax, such as the child tax credit, also shrinks the Alabama deduction and nudges state tax up a little, while a bigger federal bill does the reverse.
Worked example: a $75,000 salary in Alabama
Start with $75,000 of wages and subtract three things: $7,670 of federal income tax, the $2,500 standard deduction (the floor of the chart at this income), and the $1,500 personal exemption. That leaves $63,330 of Alabama taxable income. The first $500 costs $10 at 2%, the next $2,500 costs $100 at 4%, and the remaining $60,330 costs $3,017 at 5%. Alabama income tax totals $3,127, an effective rate of 4.17%.
The $7,670 federal figure comes from the $16,100 federal standard deduction, which leaves $58,900 taxable: $12,400 at 10%, $38,000 at 12%, and the top $8,500 at 22%. Social Security takes $4,650 and Medicare $1,088. What reaches your bank account is $58,465 a year, about $4,872 a month. The Alabama $75,000 salary breakdown splits it by pay period.
The federal deduction explains an unusual pattern. Alabama's effective rate climbs to 4.17% at $75,000, then slips to 4.02% at $150,000 and 3.88% at $250,000, because the federal tax you subtract grows faster than your pay. At $150,000 the deduction is $24,734 and Alabama tax is $6,023.
City occupational taxes
Several Alabama cities levy an occupational license tax, a flat percentage of wages earned inside city limits. Birmingham, Bessemer, Auburn, and Opelika charge 1%, which costs $750 on a $75,000 salary. Gadsden charges 2%, or $1,500. The Birmingham calculator layers the city tax on top of the state figures.
These taxes follow the job, not the home. A worker who lives in a suburb and commutes into downtown Birmingham pays the 1% tax, while a Birmingham resident whose job is outside the city does not. Employers inside a taxing city withhold it from each paycheck alongside state tax.
Unlike the state income tax, the occupational tax is a single flat rate with no brackets and no deduction for federal tax. Even so, the two track each other closely: a 1% city tax costs $750 at $75,000, about a quarter of the $3,127 state bill, and that ratio holds roughly steady at every salary we model.
Withholding, Form A-4, and working across state lines
Alabama employers set state withholding from Form A-4, the Employee's Withholding Exemption Certificate, not from the federal W-4. On it you claim your filing status and the number of dependents you support. File a new A-4 after a marriage, a divorce, or a new child, because each of those changes how much Alabama tax comes out of every check.
Because Alabama tax depends on your federal bill, a change that moves federal tax also moves state tax in the opposite direction. If a new federal credit trims your federal liability, your Alabama liability rises slightly at the same time, so expect a smaller Alabama refund that year.
Alabama has no reciprocity agreements. If you live in Alabama and work in Georgia, Georgia taxes the wages you earn there, and Alabama gives a credit on your resident return for tax paid to another state. Florida and Tennessee residents who commute into Mobile, Huntsville, or the Shoals owe Alabama tax on those wages with no home-state tax to offset it.
How Alabama compares with its neighbors
At $75,000 a single Alabama worker keeps $58,465, which ranks 38th among the 50 states and DC. Florida and Tennessee tax no wages and leave the same worker $61,592, or $3,127 more. Mississippi's flat 4% on income above $10,000 leaves $859 more. Even Georgia, which cut its flat rate to 4.99% for 2026, now leaves a $75,000 earner $133 more than Alabama does.
Alabama looks better as pay rises. At $150,000 it climbs to 26th, because the deduction for federal tax grows with income while most states offer nothing like it. See Alabama vs Tennessee or Alabama vs Georgia for side-by-side numbers.
What to expect at your income
Earning under $50,000
Below $50,000, Alabama is relatively costly because the 5% rate starts after only $3,000 of taxable income. A single filer earning $30,000 pays $1,175 to the state, a 3.92% effective rate, and takes home $25,110. At $50,000 the state bill is $2,069 and take-home pay is $40,286, or $3,357 a month. A full-time job at $20 an hour leaves $33,907 after $1,699 of Alabama tax. If you have children, list them on Form A-4, since Alabama's dependent exemption is largest at lower incomes.
Earning $50,000 to $150,000
In this range the deduction for federal tax starts doing real work. At $100,000 a single filer subtracts $13,170 of federal tax, pays $4,102 to Alabama, and takes home $75,078, about $6,257 a month. A married couple on one $100,000 salary pays $4,138 to the state and keeps $80,572. If your job is inside Birmingham, Bessemer, Auburn, or Opelika, add 1% of gross pay for the occupational tax, or 2% in Gadsden, because these figures exclude it.
Earning over $150,000
Above $150,000 Alabama's effective rate actually falls. The state takes $6,023 at $150,000, or 4.02%, and $9,695 at $250,000, or 3.88%, leaving $173,487 of take-home pay. The reason is the deduction for federal income tax, which reaches $51,304 at $250,000. Each extra dollar of federal tax trims Alabama tax by five cents. City occupational taxes get no such offset, so a 1% Birmingham tax costs about a quarter as much as the state tax at every salary we model.
Alabama paycheck tips
Keep Form A-4 current
Alabama withholding comes from Form A-4, not your federal W-4. Update it after a marriage, divorce, or new dependent so the state amount withheld matches your situation.
Price the job's address, not your home's
Occupational taxes apply where you work. A job in Gadsden costs 2% of gross pay and one in Birmingham 1%, even if you live outside the city.
Claim the credit if you work in Georgia
Georgia withholds its tax on wages earned there. File a Georgia nonresident return and claim Alabama's credit for tax paid to another state so the same wages are not taxed twice in full.
Recheck after a big federal change
A raise, a new child, or a new federal credit changes your federal tax, which changes your Alabama deduction. Run the numbers again in the Alabama paycheck calculator after any such change.
Plan for bonus withholding
A bonus paid separately has federal tax withheld at a flat 22%, and Alabama tax comes out as well. The bonus tax calculator shows what will land in your account.
Common mistakes
Treating 5% as a high-earner rate
In many states the top rate only reaches large incomes. In Alabama it applies above $3,000 of taxable income, so a $30,000 earner's last dollar faces the same 5% as a $250,000 earner's.
Confusing federal withholding with federal tax owed
Alabama lets you deduct the federal income tax you owe for the year, not the amount withheld from your pay. A large federal refund does not mean a larger Alabama deduction.
Forgetting the occupational tax after a job change
Moving from a job outside city limits to one in Birmingham adds $750 a year at $75,000, and $1,500 in Gadsden. Budget for it before you accept the offer.
Moving to or from Alabama
Moving to Alabama
Moving to Alabama from Florida or Tennessee adds a state income tax of $3,127 at $75,000, since neither of those states taxes wages. Coming from Georgia, a single $75,000 earner keeps $133 less in Alabama after Georgia's 2026 rate cut. Check whether the job sits inside Birmingham, Bessemer, Gadsden, Auburn, or Opelika, where an occupational tax takes 1% to 2% of gross pay, and give your new employer a Form A-4 so state withholding starts correctly.
Leaving Alabama
Leaving Alabama for Tennessee or Florida saves the full $3,127 a $75,000 earner pays the state, plus any city occupational tax. Mississippi saves $859 at that salary, and Georgia $133. Higher earners give up Alabama's most valuable feature when they leave: the deduction for federal income tax, which is worth more as income rises. Expect to file Alabama Form 40NR as a part-year resident for the year you move.
