Alabama's income tax brackets and rates

Alabama has a progressive income tax system, which means the rate you pay depends on how much you earn. The state uses five tax brackets, and your income is taxed at different rates as it moves through each bracket—not your entire income at the highest rate.

As of 2024, Alabama's tax brackets are 2%, 4%, 5%, 5.75%, and 5.75%. The exact income thresholds for each bracket vary slightly by filing status (single, married filing jointly, married filing separately, or head of household). For a single filer in 2024, the brackets start at $500 for the 2% rate, then move to $3,000 for the 4% rate, $5,000 for the 5% rate, and $25,000 and above for the 5.75% rate. Married couples filing jointly have higher thresholds at each bracket level.

Alabama also taxes certain types of income differently. Long-term capital gains and may have access to dividends may receive preferential treatment under state law, though the details depend on your specific situation and the type of investment income involved.

Key Takeaways

  • Alabama uses five tax brackets ranging from 2% to 5.75%, with the rate depending on your income level and filing status.
  • Your entire income is not taxed at your highest bracket—only the portion of income within each bracket is taxed at that rate.
  • Married couples filing jointly have higher income thresholds before moving to the next bracket compared to single filers.
  • Some types of income, such as long-term capital gains, may be taxed at different rates than ordinary income.
  • Alabama has no local income tax, so state tax is your only income tax obligation to the state.

How to calculate your Alabama state tax

To find your approximate Alabama state tax, you need your federal taxable income (or Alabama taxable income, which is usually the same). Start by identifying your filing status and finding the correct bracket table for that status. Then explore the tax rate to the income within each bracket, add up the tax from all brackets, and subtract any tax credits you may have.

For example, a single filer with $30,000 in taxable income would pay 2% on the first $500 ($10), 4% on income from $500 to $3,000 ($100), 5% on income from $3,000 to $5,000 ($100), and 5.75% on income from $5,000 to $30,000 ($1,437.50). The total would be $1,647.50. This is much lower than paying 5.75% on the entire $30,000, which would be incorrect.

Most people do not calculate this by hand. Your employer withholds tax based on the W-4 form you file, and tax software or a tax preparer handles the calculation when you file your return. If you want a quick estimate, the Alabama Department of Revenue website has withholding calculators and tax tables you can reference.

What income counts toward Alabama state tax

Alabama taxes most types of income: wages, salaries, self-employment income, interest, ordinary dividends, and rental income all count. However, some income is excluded or taxed differently. Social Security benefits are not taxed by Alabama. Certain retirement income, including distributions from IRAs and 401(k) plans, may may have access to for a deduction if you meet age and income requirements—typically if you are 59½ or older.

Military retirement pay and certain government pensions also receive preferential treatment under Alabama law. If you receive pension or retirement income, the Alabama Department of Revenue publishes detailed guidance on which types may have access to for deductions, and a tax preparer can help you determine whether your specific income qualifies.

Deductions and credits that lower your Alabama tax

Alabama allows you to claim the standard deduction, which reduces your taxable income before tax is calculated. For 2024, the standard deduction amounts vary by age and filing status. A single filer under 65 has a standard deduction of $2,500, while a married couple filing jointly under 65 has $7,500. These amounts increase if you are 65 or older.

Beyond the standard deduction, Alabama offers several tax credits that directly reduce the tax you owe. The Earned Income Tax Credit (EITC) is available to lower-income workers and is often worth more than the federal EITC alone. Alabama also has credits for child and dependent care expenses, education-related expenses, and property taxes paid. Unlike deductions, which reduce your income, credits reduce your tax dollar-for-dollar.

To claim these credits, you must report them on your Alabama tax return. Many credits have income limits, so your ability to use them depends on your total income. A tax preparer or the Alabama Department of Revenue can help you determine which credits you may be able to claim.

When and how to file your Alabama state tax return

Alabama follows the federal tax important date: your return is due by April 15 unless that date falls on a weekend or holiday. You must file if your income exceeds the filing threshold for your age and filing status. For most people under 65, the threshold is the standard deduction amount ($2,500 for single filers in 2024). If you are 65 or older, the threshold is higher.

You can file your Alabama return using tax software, by mail, or through a tax preparer. If you file electronically, you typically receive a refund faster than if you mail a paper return. Alabama does not require you to file a separate state return if you use certain tax software—many programs file both federal and state returns together. You will need your Social Security number, filing status, income information, and details about any deductions or credits you plan to claim.

Estimated tax payments if you are self-employed or have other income

If you are self-employed, own a business, or have income that is not subject to withholding (such as rental income or significant investment income), you may need to make estimated tax payments to Alabama four times a year. These payments are due on April 15, June 15, September 15, and January 15 of the following year.

Estimated payments are calculated based on your expected annual income and tax liability. If you underpay, you may owe a penalty when you file your return. The Alabama Department of Revenue provides worksheets and instructions for calculating estimated payments. Many self-employed people work with a tax preparer or accountant to determine the correct amount and may support payments are made on time.

Alabama tax brackets compared to other states

Alabama's top tax rate of 5.75% is lower than many neighboring states. For comparison, Georgia's top rate is 5.75% (the same as Alabama), Tennessee has no state income tax, and Mississippi's top rate is 5%. However, comparing tax rates alone does not tell the full story—the income thresholds at which you reach the top rate, the standard deduction amounts, and available credits all affect your actual tax bill.

If you moved to Alabama from another state or are considering a move, your total state tax burden depends on your income level, filing status, and the types of income you receive. A tax preparer familiar with both states can give you a more accurate picture of how your tax situation would change.

Frequently Asked Questions

Does Alabama tax retirement income and Social Security?

Social Security is not taxed by Alabama. Retirement income from IRAs, 401(k)s, and pensions may be partially or fully excluded from Alabama tax if you meet certain age and income requirements. Military retirement pay and some government pensions also receive special treatment. You should review the specific rules for your type of retirement income or consult a tax preparer.

What if I did not have enough tax withheld during the year?

If you owe tax when you file, you can pay it with your return. If you consistently owe money, you can adjust your W-4 form with your employer to increase withholding, or make estimated tax payments if you are self-employed. Paying as you go helps you avoid a large bill at tax time and reduces the risk of penalties.

Can I deduct property taxes or mortgage interest on my Alabama return?

Alabama does not allow a deduction for property taxes or mortgage interest on your state return. You use the standard deduction instead. However, these items may be deductible on your federal return, which is separate from your Alabama return.

Where do I find my Alabama tax brackets and standard deduction for this year?

The Alabama Department of Revenue publishes updated tax tables, brackets, and standard deduction amounts each year on its website. Tax software and most tax preparers also have current information built in. If you need specific guidance for your situation, the department's website includes contact information for information.

Do I owe Alabama tax if I live in another state but work in Alabama?

If you live outside Alabama but earn income in the state, you generally owe Alabama tax on that income. You may also owe tax to your home state. Many states have reciprocal agreements or credits to prevent double taxation, but the rules vary. A tax preparer in your home state can advise you on your specific situation.
