Alabama does have a state income tax

Alabama taxes wages, salaries, and most other income at the state level. The state does not have a flat tax rate — instead, it uses a progressive system with brackets that change based on how much you earn. For 2024, Alabama's income tax rates range from 2% on the lowest bracket to 5% on the highest.

This means Alabama is not one of the nine states with no income tax. If you work in Alabama or live there and earn income from any source, you will owe state income tax unless you fall into a specific exemption category. The amount you pay depends on your filing status, total income, and what deductions you can claim.

Key Takeaways

  • Alabama's state income tax rates range from 2% to 5% depending on your income bracket and filing status.
  • You must file a state return if you earn income in Alabama, even if you do not owe federal tax.
  • Alabama allows you to deduct your federal income tax paid, which can lower your state tax bill.
  • Certain types of income, such as Social Security benefits and some retirement distributions, may be partially or fully exempt from Alabama state tax.

Alabama's income tax brackets for 2024

Alabama uses four tax brackets for single filers and four for married filers filing jointly. The brackets are adjusted each year for inflation, so the income thresholds change. For 2024, a single filer pays 2% on income up to roughly $500, then 4% on income between $500 and $3,000, then 5% on income above $3,000.

Married couples filing jointly have higher thresholds at each bracket level, which means they can earn more before moving into a higher tax rate. Head of household filers have their own bracket structure as well. The exact dollar amounts shift annually, so you should check the Alabama Department of Revenue website or your tax forms each year to confirm the current brackets.

Your effective tax rate — the actual percentage of your total income you pay in tax — will be lower than the top bracket rate you fall into, because you only pay the higher rate on income above each threshold.

What income Alabama taxes and what it does not

Alabama taxes wages, salaries, tips, interest, dividends, capital gains, and business income. If you receive a W-2 from an employer or 1099 from self-employment, that income is subject to Alabama state tax. Rental income, investment income, and income from side work all count as well.

Some types of income are partially or fully exempt. Social Security benefits are not taxed by Alabama. Distributions from certain retirement accounts, including some IRA withdrawals and pension payments, may be exempt if you meet age or other requirements — the rules vary depending on the type of account and when you opened it. Military retirement pay and certain federal employee pensions also receive preferential treatment under Alabama law.

The best way to know whether a specific type of income you receive is taxable is to check the instructions for the Alabama Form 40 (the main state income tax return) or contact the Alabama Department of Revenue directly.

How to file your Alabama state income tax return

You file your Alabama state return using Form 40 if you are a resident, or Form 40-NR if you are a nonresident who earned income in the state. You can file by mail or electronically through the Alabama Department of Revenue website. Most tax software that handles federal returns also handles Alabama returns, so if you use TurboTax, H&R Block, or a similar service, you can usually add the state return as part of the same process.

The deadline to file is the same as the federal deadline, which is typically April 15 unless that date falls on a weekend or holiday. If you file your federal return and request an extension, the extension also applies to your Alabama return. You can request an extension through the Alabama Department of Revenue or through your tax software.

If you owe Alabama income tax, you can pay online through the department's website, by mail, or through an authorized payment processor. If you are due a refund, direct deposit is usually the fastest way to receive it.

Deductions and credits that lower your Alabama tax bill

Alabama allows you to deduct the federal income tax you paid during the year, which is one of the largest deductions available. You can also claim the standard deduction, which varies by filing status and age. For 2024, the standard deduction for a single filer under 65 is $2,500; for married filing jointly it is $7,500. If you are 65 or older, you get an additional deduction.

Alabama also offers a child and dependent care credit, an education credit for certain higher education expenses, and a credit for taxes paid to other states if you worked in multiple states during the year. Some taxpayers can claim a credit for property taxes paid as well. The amount of each credit depends on your specific situation.

If your income is very low, you may not owe any state tax at all, even if you have some income. The threshold depends on your filing status and age. You can find the current income thresholds on the Alabama Department of Revenue website or in the Form 40 instructions.

What happens if you do not file or pay

If you owe Alabama state income tax and do not file or pay, the state can assess penalties and interest on the unpaid amount. The penalty for failure to file is typically 5% per month, up to 25% of the tax owed. Interest accrues daily at a rate set by the state, which changes quarterly.

The Alabama Department of Revenue can also place a lien on your property, garnish your wages, or offset your state refund to collect unpaid taxes. If you cannot pay in full, you can contact the department to discuss a payment plan or other options. The sooner you reach out, the more options are usually available to you.

Frequently Asked Questions

Do I have to file an Alabama return if I only earned a small amount of income?

You must file if your income exceeds the threshold for your filing status and age. The threshold is lower than the standard deduction in some cases, so you may owe tax even if you do not itemize deductions. Check the Form 40 instructions or the Alabama Department of Revenue website for the current threshold for your situation.

Can I claim the federal standard deduction on my Alabama return?

No. Alabama has its own standard deduction, which is separate from the federal standard deduction. You must use the Alabama standard deduction amount on your state return, even if you itemized deductions on your federal return or vice versa.

What if I moved to Alabama partway through the year?

You file as a part-year resident and report only the income you earned while living in Alabama. You may also owe tax to your previous state on income earned there. Some states have reciprocal agreements with Alabama, which can affect how much you owe to each state.

Does Alabama tax retirement income differently than wages?

Some retirement income is exempt, but not all. Social Security is fully exempt. Military retirement and certain federal pensions receive preferential treatment. Other retirement account distributions are taxed as ordinary income unless they fall into a specific exemption category. The type of account and your age determine the tax treatment.

Where do I send my Alabama tax return if I file by mail?

The mailing address depends on whether you are enclosing a payment. The Form 40 instructions include the correct address for your situation. You can also file electronically through the Alabama Department of Revenue website, which is usually faster and reduces the chance of errors.
