Alabama Paycheck Calculator (2026)

Estimate your Alabama take-home pay after federal tax, FICA, and Alabama state income tax.

How this calculator works

Like our other paycheck calculators, this estimates federal tax and FICA the same way regardless of state. On top of that, it applies Alabama’s own state income tax: a phasing standard deduction that goes DOWN as your income goes up, a flat personal exemption, an uncapped deduction for the federal income tax you’re estimated to owe, and then Alabama’s 2%/4%/5% bracket schedule (doubled thresholds for a joint return). Alabama has no state disability insurance tax and no employee-paid unemployment tax, so state income tax is the only state-level line on the breakdown below. About 25 Alabama cities add their own local occupational tax on top of this (see the FAQ), which this calculator does not model.

The federal-tax deduction is the most unusual part of Alabama’s system: this calculator uses the federal tax liability it already computes for you (not an employer-withholding estimate) as the deduction, since that’s a closer match to what the Alabama statute actually describes, and this calculator’s whole model is built around annual tax liability rather than simulating paycheck-by-paycheck withholding tables.

The formula

(federal tax, FICA, and net-pay assembly are identical to the Texas calculator)

alWages           = grossWages − pretaxHealth − 401(k) contribution

standardDeduction = phases DOWN as alWages rises:
                   single: $3,000 at or below $25,999, minus $25 per $500
                     increment above that, floor $2,500 at $35,500+
                   joint:  $8,500 at or below $25,999, minus $175 per $500
                     increment above that, floor $5,000 at $35,500+

personalExemption = $1,500 (single) or $3,000 (joint)

alTaxable   = max(0, alWages − standardDeduction − federalTax − personalExemption)
alIncomeTax = 2026 AL bracket schedule applied to alTaxable
            (2% / 4% / 5%, thresholds $500/$3,000 single, $1,000/$6,000 joint)

stateTax    = alIncomeTax

Worked example

A single filer earning $60,000/year, paid biweekly, with no 401(k) or extra deductions:

  • FICA: $4,590.00/year (same as any state)
  • Federal tax: $5,020.00/year (same as any state)
  • Alabama standard deduction: gross income $60,000 is above the $35,500 phase-down floor, so the deduction sits at its minimum, $2,500.00
  • Federal tax deduction: $5,020.00 (this calculator’s own computed federal liability)
  • Personal exemption: $1,500.00
  • Alabama taxable income: $60,000 − $2,500 − $5,020 − $1,500 = $50,980.00
  • Alabama income tax: $500 × 2% + $2,500 × 4% + $47,980 × 5% = $10.00 + $100.00 + $2,399.00 = $2,509.00/year
  • Net pay: $60,000 − $4,590 − $5,020 − $2,509 = $47,881.00/year, or $1,841.58 per biweekly paycheck

We separately verified this calculator’s Alabama tax math against the Alabama Department of Revenue’s own official worked example, printed in its withholding tax booklet: for a married filer with $44,200 of gross wages, a $1,830 estimated federal withholding deduction, and 2 dependents, the booklet computes $1,538.50 of Alabama tax for the year. Running the same inputs through this calculator’s formula, but without the 2 dependents (this calculator doesn’t collect a dependents count, matching our other state calculators), gives $1,638.50, exactly $100.00 more, which is exactly the $2,000 dependent exemption the booklet includes multiplied by the 5% top bracket rate it falls entirely within. Every other intermediate figure (gross income, standard deduction, personal exemption, taxable income, and each bracket’s tax) matched the booklet’s own printed numbers exactly.

Frequently asked questions (FAQ)

Why are Alabama's tax brackets so low compared to other states?

Alabama's 2%/4%/5% brackets top out at just $3,000 of taxable income for a single filer ($6,000 joint), a structure that has been in place for decades. In practice this means almost all Alabama wage income above the standard deduction and personal exemption is taxed at the top 5% rate, so the low thresholds matter less than they look.

Does Alabama really let me deduct my federal income tax from my state taxes?

Yes. Code of Alabama section 40-18-15(c) allows an uncapped deduction for the federal income tax you paid or accrued for the year when computing your Alabama taxable income. Very few states do this at all, and none in this codebase's state library cap it the way some do, so a higher federal tax bill actually shrinks your Alabama state tax bill.

Why does my standard deduction go down as I earn more in Alabama?

Alabama's standard deduction phases DOWN as gross income rises, the opposite of a typical deduction. A single filer's deduction starts at $3,000 and steps down by $25 for every $500 of income above $25,999, bottoming out at a $2,500 floor once gross income reaches $35,500. Joint filers phase from $8,500 down to a $5,000 floor the same way.

Does Alabama have a state disability insurance or paid family leave tax on my paycheck?

No. Alabama has no mandatory State Disability Insurance or Paid Family Leave payroll tax (unlike California, New Jersey, New York, and a few other states), and Alabama unemployment insurance is funded entirely by employer contributions. Alabama state income tax is the only state-level tax line on an Alabama paycheck.

Does my city add its own income tax on top of Alabama’s state tax?

Possibly. About 25 Alabama cities, including Birmingham, Bessemer, Gadsden, and Auburn, levy a local occupational tax of roughly 0.5% to 2% of gross wages, separately administered by each city rather than the state. This calculator estimates state-level Alabama tax only, so your actual paycheck in one of these cities will be somewhat lower than shown here.

Does contributing to a 401(k) lower my Alabama state tax the way it lowers my federal tax?

Yes. Alabama excludes 401(k) elective deferrals and Section 125 pre-tax health premiums from wages the same way federal withholding does, so a 401(k) contribution lowers both your federal taxable wages and the wage figure Alabama's own standard deduction, personal exemption, and bracket math are applied to.
