## Assumptions

- An estimate for a full-year resident, 2026 rates, not tax advice.
- Starts from federal AGI; Alabama additions and subtractions are not modelled.
- Not modelled for Alabama: Deducts federal income tax paid. Local occupational taxes are typed by the user.
- An empty federal tax is the federal rate schedule on AGI less the standard deduction.
- Not modelled: part-year and nonresident returns, other state credits, and state AMT.

## FAQ

### What is the Alabama income tax rate?

Alabama taxes income at 2% to 5% in 3 brackets (single filers). For a single filer the schedule is 2% from $0, 4% from $500, 5% above $3,000 of taxable income. These are the 2026 rates.

### How is Alabama income tax calculated?

Start from federal adjusted gross income. Subtract the larger of the Alabama standard deduction and your itemized deductions, then the exemptions. Apply the rates to what is left and subtract any credits. The standard deduction is $3,000 single, $8,500 married filing jointly, $4,250 separately, and $5,200 head of household. It shrinks as income rises. The model takes a personal exemption of $1,500 ($3,000 joint), dependent exemptions that depend on income, a deduction for federal income tax paid.

### Does Alabama have a local income tax?

This page has no local income tax for Alabama; if your city or county has one, add it yourself.

### What does this Alabama calculator leave out?

Deducts federal income tax paid. Local occupational taxes are typed by the user. It also leaves out state additions and subtractions to federal AGI (such as retirement or Social Security exclusions), part-year and nonresident returns, and credits such as child care, earned income, and tax paid to another state.

### Which tax year do the Alabama rates cover?

Tax year 2026, the return you file in 2027. They come from Alabama Department of Revenue.

### Which states have no income tax on wages?

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. They have no page of their own, because there is no wage income tax to work out; the state income tax calculator answers 0 for them. Federal income tax and Social Security and Medicare still apply.

### Is this the same as my paycheck withholding?

No. This is the tax for the whole year on your return. Your employer withholds by the state's own withholding formula, so your refund or balance due is the difference between the two.
