Alabama does have a state income tax

Alabama taxes your income at the state level. Unlike a handful of states that have no income tax at all, Alabama collects income tax from wages, self-employment earnings, investment income, and other sources. The tax rate depends on your income bracket — Alabama uses a progressive system where higher earners pay a higher percentage.

If you work in Alabama or live there, you will owe state income tax on most types of income. The state also taxes retirement income, though some types of retirement income receive preferential treatment or exemptions. Understanding what Alabama taxes and at what rate helps you plan for tax season and understand your paychecks.

Key Takeaways

  • Alabama has state income tax with rates ranging from 2% to 5.75% depending on your income bracket.
  • You owe Alabama income tax if you live in the state or earn income there, even if you work remotely for an out-of-state employer.
  • Certain retirement income, including some pension and Social Security payments, may be exempt or partially exempt from Alabama state income tax.
  • Your employer withholds Alabama income tax from your paycheck if you live or work in the state, similar to federal withholding.

Alabama's income tax brackets and rates

Alabama uses five tax brackets. As of the current tax year, the rates are 2%, 4%, 4.5%, 5%, and 5.75%. The bracket you fall into depends on your filing status (single, married filing jointly, head of household, or married filing separately) and your taxable income after deductions.

The brackets adjust slightly each year for inflation, so the exact income thresholds change annually. For example, a single filer in the lowest bracket pays 2% on income up to a certain amount, then moves to the next bracket for income above that threshold. This means you do not pay the top rate on all your income — only on the portion that falls within the highest bracket you reach.

You can find the current year's exact bracket thresholds on the Alabama Department of Revenue website or on your tax forms. Many tax software programs also fill in the correct brackets automatically based on your filing status and income.

What income Alabama taxes

Alabama taxes wages and salaries, self-employment income, interest and dividends, capital gains, rental income, and most other forms of income. If you receive a W-2 from an employer, that income is taxable. If you receive a 1099 for freelance or contract work, that is also taxable in Alabama.

Some types of income receive special treatment. Social Security benefits are generally not taxed by Alabama, though the state does tax some retirement income. Pension income from public employees (teachers, police, firefighters) may be partially or fully exempt depending on when you retired and your age. Military retirement pay also receives preferential treatment in some cases.

Investment income — interest from savings accounts, dividends from stocks, and capital gains from selling investments — is taxable. Long-term capital gains (assets held more than one year) are taxed at the same rates as ordinary income in Alabama, unlike the federal system which has preferential rates for long-term gains.

Retirement income and exemptions

Alabama does not tax Social Security benefits, which is a significant advantage for retirees. However, other retirement income is taxable unless it falls under a specific exemption.

Public employee pensions — including those for teachers, state employees, and local government workers — are exempt from Alabama income tax if you retired before January 1, 2011, or if you were at least 59½ years old when you retired. If you retired after that date and were younger than 59½, your pension is taxable.

Military retirement pay is exempt from Alabama income tax, regardless of your age or when you retired. This applies to both active-duty and reserve military pensions. Private sector pensions and 401(k) withdrawals are taxable as ordinary income.

How withholding works in Alabama

If you work in Alabama or live there, your employer withholds state income tax from your paycheck automatically, just like federal withholding. The amount withheld depends on the information you provide on your W-4 form and your income level.

You can adjust your withholding by submitting a new W-4 to your employer. If you want less tax withheld (for example, if you have a second job or significant deductions), you can claim additional allowances. If you want more withheld to avoid owing at tax time, you can request that as well.

Self-employed people do not have withholding taken out automatically. Instead, you pay estimated taxes quarterly to the Alabama Department of Revenue. These payments are due in April, June, September, and January of the following year.

Remote work and out-of-state employment

If you live in Alabama but work remotely for an out-of-state employer, you still owe Alabama state income tax on your wages. Alabama taxes residents on all income earned, regardless of where the employer is located. Your employer may not withhold Alabama tax if they are based elsewhere, which means you may need to pay estimated taxes or settle the balance when you file your return.

If you work in Alabama but live in another state, you may owe Alabama income tax on the wages you earn while working in the state. Some states have reciprocal agreements that prevent double taxation, but Alabama's agreements are limited. You should check with both states' tax departments to understand your obligations.

Many remote workers discover withholding issues when they file their return. If your employer did not withhold Alabama tax, you can adjust your W-4 with them going forward, or you can make estimated quarterly payments to avoid a large bill at tax time.

Filing your Alabama state return

You file your Alabama state income tax return using Form 40 (for residents) or Form 40-NR (for nonresidents). The return is due on the same date as your federal return — typically April 15, though the important date shifts if that date falls on a weekend or holiday.

You can file online through the Alabama Department of Revenue website, by mail, or through tax software that supports Alabama returns. Many free tax software options include Alabama state returns at no additional cost if your income is below a certain threshold.

If you owe money, you can pay online, by mail, or through an installment plan. If you are due a refund, the state typically processes it within four to six weeks if you file electronically, or longer if you mail a paper return.

Frequently Asked Questions

Do I have to file an Alabama state return if I only lived there part of the year?

If you were a resident for any part of the tax year, you file a resident return on all your income. If you moved to Alabama partway through the year, you file a nonresident return (Form 40-NR) on income earned while you were a resident. The rules depend on your specific situation, so check the Alabama Department of Revenue website or speak with a tax professional.

What if I moved out of Alabama during the year?

You file a nonresident return (Form 40-NR) for the portion of the year you lived in Alabama. You report only the income you earned while you were a resident. Your new state may also require a return for the portion of the year you lived there.

Can I deduct federal income tax from my Alabama return?

No. Alabama does not allow a deduction for federal income taxes paid. However, you can claim the standard deduction or itemize deductions (mortgage interest, charitable contributions, state and local taxes up to a limit) just as you do on your federal return.

What happens if I do not pay my Alabama income tax?

The Alabama Department of Revenue can assess penalties and interest on unpaid taxes. They may also place a lien on your property or garnish your wages. If you cannot pay in full, contact the department about setting up a payment plan before the bill becomes larger.

Is there a tax credit for taxes paid to another state?

Alabama does not offer a credit for income taxes paid to other states. If you worked in multiple states and owe tax to both, you pay both. Some states offer credits to prevent double taxation, but Alabama is not one of them.
