Alabama Paycheck & Income Tax Calculator

How Alabama income tax works

Alabama has three bands, and they are over almost before they start. For a single filer: 2% on the first $500 of taxable income, 4% on the next $2,500, and 5% on everything above $3,000. Filing jointly, the break points are $1,000 and $6,000.

The graduated part therefore covers the first $3,000 and raises $110. Against charging a flat 5% on everything, the two lower bands are worth $40 a year — three percentage points on $500 plus one point on $2,500. For anyone earning a normal wage, Alabama is a flat 5% state.

What makes the bill much smaller than 5% of a salary is what comes off first, and Alabama subtracts three separate things:

• a standard deduction, banded by income — $2,500 for a single filer at any ordinary wage
• a personal exemption of $1,500 ($3,000 joint), separate from the deduction
• your entire federal income tax bill

A single filer on $75,000 subtracts $2,500, then $1,500, then $7,670 of federal tax, leaving $63,330 of Alabama taxable income and about $3,127 for the year — an effective state rate of roughly 4.2%, not 5%.

You deduct your federal tax bill

This is the single most important thing about Alabama’s income tax, and most calculators do not apply it at all.

Alabama lets you subtract the federal income tax you paid, in full, before it works out what you owe the state. Form 40 line 12 is “Federal Income Tax Deduction”, and the instructions say only to use your federal return and the accompanying worksheet. There is no cap.

The right is constitutional rather than statutory — Amendment 225 to the Constitution of Alabama of 1901 provided the deduction, which is why it has survived where other states have repealed theirs. Very few states allow it at all, and of those that do, most limit it.

The scale is easy to underestimate. On $75,000, a single Alabamian subtracts:

The federal deduction alone is worth $383.50 of Alabama tax — nearly double what the standard deduction and personal exemption save between them.

It also produces a property no other kind of allowance has: your Alabama tax falls when your federal tax rises. A federal tax cut, all else equal, raises what you owe Alabama, because there is less federal tax left to deduct. That is worth knowing whenever Congress changes rates.

The order matters too, and the state’s own Form 40ES worksheet spells it out: adjusted gross income, less the standard deduction, less federal tax liability, less the exemptions — and what remains is Alabama taxable income.

A deduction that shrinks in $25 steps

Alabama does not give everyone the same standard deduction, and it does not taper it smoothly either. It uses a chart of twenty-one income bands.

For a single filer it begins at $3,000 for income up to $25,999, then falls by $25 for each $500 of income, band by band, until it reaches $2,500 at $35,500 and stops. Filing jointly it starts at $8,500 and falls by $175 a band to a floor of $5,000, over exactly the same income range.

Two things follow. First, the whole mechanism plays out between $26,000 and $35,500 — a stretch of under $10,000 — so it affects a narrow band of low-to-middle incomes and nobody else. Second, almost every full-time worker is already at the floor. A single filer on $40,000 gets the same $2,500 as one on $400,000.

The amount at stake is small: $500 of deduction across the whole slide, worth $25 a year at the 5% rate. It is a fiddly piece of machinery for a modest sum, but it is real, and the calculator above applies the correct band at every income rather than assuming the floor.

The personal exemption sits alongside it and does not move at all.

Take-home pay at every salary in Alabama

After federal tax, Alabama state tax and FICA, with the federal tax deduction applied at each income and the correct standard deduction band. City occupational taxes are not included, for the reason below.

What lands in your account each payday

On $75,000 a year in Alabama, filing single, split across the pay schedules employers actually use.

The city occupational taxes

Alabama has no statewide local income tax, but a number of cities levy an occupational tax or license fee on wages earned inside their limits, and the rates differ from place to place.

Birmingham and Auburn charge 1%; Gadsden charges 2%. Others, including Irondale and Leeds, set their own. In Jefferson County a county-level occupational tax can apply on top of a city one, so some workers face two layers.

The important rule is that these generally follow where you work, not where you live. Commuting into Birmingham attracts the Birmingham tax on the wages earned there, whether or not you live in the city; the employer normally withholds it and remits it directly.

On a $75,000 salary a 1% occupational tax is $750 a year — around a quarter as much again on top of the $3,127 of state income tax, and nearly nineteen times what Alabama’s entire graduated rate structure is worth.

Because the rates vary by city and no statewide equivalent exists, they are not in the figures on this page. If you work in a city that levies one, add its rate to your gross wages.

Dates that matter for the 2026 tax year

Alabama returns (Form 40) are due on the same date as the federal return, April 15, 2027 for the 2026 tax year. The instructions put it plainly: file as soon as you can after January 1, but no later than the federal due date.

Estimated payments, if required, fall quarterly. Alabama only requires them where the estimated tax comes to $500 or more after withholding, which the federal tax deduction keeps many wage earners below.

Questions people ask

What are the Alabama income tax rates for 2026?

Three bands. For a single filer, 2% on the first $500 of taxable income, 4% on the next $2,500, and 5% on everything over $3,000. Filing jointly the bands are $1,000 and $6,000. In practice Alabama is a flat 5% state, because the graduated part ends so early.

Can I deduct my federal income tax in Alabama?

Yes, all of it. Alabama is one of very few states that allows a deduction for federal income tax paid, and unlike the states that cap it, Alabama's is unlimited. It comes from Amendment 225 to the state constitution, and appears on line 12 of Form 40.

What is the Alabama standard deduction?

It depends on your income. It starts at $3,000 for a single filer and $8,500 filing jointly, then steps down every $500 of income until it reaches $2,500 and $5,000 at $35,500. Almost every full-time worker gets the floor.

Is there an Alabama personal exemption?

Yes, and it is separate from the standard deduction. Form 40 instructs single filers to enter $1,500 and joint filers $3,000. There is a further dependent exemption, itself banded by income, which this calculator does not apply.

Why is my Alabama tax lower than 5% of my salary?

Mostly because of the federal tax deduction. On $75,000 a single filer subtracts $7,670 of federal tax before Alabama charges anything, which saves about $384 — nearly double what the standard deduction and personal exemption save between them.

Does any Alabama city charge a tax on wages?

Several do, through occupational taxes or license fees. Birmingham and Auburn charge 1% and Gadsden 2%, and others levy their own rates. They generally follow where you work rather than where you live. Nothing statewide corresponds to them, so they are not in the figures here.

Are Alabama payroll deductions taken from my paycheck?

Not by the state. Alabama unemployment insurance is employer-funded and the state runs no disability or paid family leave program. Beyond state income tax and any city occupational tax, the only deductions are federal.
