Alabama Income
Tax Rates & Rules

Rates, brackets, filing rules, withholding, residency and the 2026 overtime premium deduction.

Alabama has a graduated individual income tax with rates of 2 percent, 4 percent and 5 percent. The top 5 percent rate begins at relatively low taxable-income levels, so most taxpayers with moderate or higher Alabama taxable income reach the top marginal state rate. The amount actually owed still depends on filing status, deductions, exemptions, credits and whether the taxpayer is a full-year resident, part-year resident or nonresident.

For 2026, Alabama also added a new overtime premium deduction that can reduce Alabama taxable income for eligible taxpayers. Payroll withholding is separate from the final annual return, so the amount withheld from a paycheck is not automatically the same as the taxpayer's final Alabama income tax liability.

Alabama Income Tax Rates and Brackets for 2026

Alabama uses three marginal income tax rates. The brackets differ slightly for married couples filing jointly compared with single taxpayers, heads of family and married taxpayers filing separately.

These are marginal brackets. Reaching the 5 percent bracket does not mean every dollar of Alabama taxable income is taxed at 5 percent. The lower portions remain taxed at the lower rates.

How Alabama Taxable Income Is Calculated

Alabama taxable income is generally determined by starting with Alabama income, applying state-specific adjustments then subtracting allowable deductions and exemptions. Alabama does not simply copy the federal taxable-income calculation.

A simplified sequence is:

• Determine Alabama gross income and state-specific additions or exclusions.
• Calculate Alabama adjusted gross income.
• Choose the Alabama standard deduction or itemized deductions when eligible.
• Subtract the applicable personal exemption plus dependent exemptions.
• Apply any other state deductions that are allowed for the tax year.
• Apply the Alabama marginal tax rates to the resulting taxable income.
• Subtract eligible credits to determine final state tax liability.

Alabama allows taxpayers to compare the state standard deduction with itemized deductions and use the method that provides the greater benefit. The state choice is not automatically controlled by whether the taxpayer itemizes on the federal return.

Alabama Standard Deduction and Personal Exemptions

Alabama's standard deduction depends on filing status and Alabama adjusted gross income. The amount generally decreases as income rises within the state's standard-deduction schedule.

The current state schedule provides maximum standard deductions of $8,500 for married filing jointly, $5,200 for head of family, $4,250 for married filing separately and $3,000 for single taxpayers at the lower income levels shown in the schedule. Higher-income taxpayers can receive smaller standard deductions under the chart.

Separate personal exemptions also apply. Single taxpayers and married taxpayers filing separately receive a $1,500 personal exemption. Married filing jointly and head of family receive a $3,000 personal exemption.

Who Has to File an Alabama Income Tax Return?

Alabama filing requirements depend on residency, filing status and gross income. Full-year residents generally file once gross income reaches the state threshold for their filing status.

Part-year residents use the same current gross-income thresholds for the period they were Alabama residents. Nonresidents generally must file when Alabama-source income exceeds the allowable prorated personal exemption.

Residents, Part-Year Residents and Nonresidents

Alabama residents are generally taxed on income from all sources while they remain domiciled in Alabama. A temporary absence does not automatically end Alabama residency for income tax purposes.

Part-year residents generally report income earned while they were Alabama residents. Nonresidents can owe Alabama tax on Alabama-source income, including compensation for services performed in the state. Depending on the facts, a taxpayer who changed residency during the year can need both a resident or part-year return and Form 40NR for Alabama-source income received while a nonresident.

Remote work can therefore create state-tax questions. An Alabama resident working remotely for an employer in another state can still be subject to Alabama income tax because Alabama residents are generally taxed on income from all sources. A nonresident working physically in Alabama can also have Alabama-source wages.

What Changed for Alabama Overtime in 2026?

Beginning with calendar year 2026, Alabama allows an income-tax deduction for the premium portion of eligible overtime wages. The deduction is available through 2028 under the current law.

The deductible amount is the lesser of the actual overtime premium or $1,000 per taxpayer for the year. Only the premium portion above the employee's regular rate counts. If an employee earns time and one-half, the one-half premium is the relevant amount rather than the entire overtime payment.

This is different from the earlier Alabama overtime exemption that ended in 2025. Payroll teams and taxpayers should not reuse the old exemption rules for 2026.

Alabama Withholding Tax From Paychecks

Employers generally withhold Alabama income tax from taxable employee wages using Alabama Form A-4 and the current state withholding methods. The withholding calculation uses Alabama-specific exemptions and payroll-period rules.

Withholding is a prepayment of expected annual tax. A worker can have too much or too little withheld depending on compensation, exemptions, multiple jobs, deductions and other income. If the goal is to estimate the effect of Alabama withholding on take-home pay, the Alabama paycheck calculator is the more appropriate tool because it combines state withholding with federal payroll taxes and other deductions.

Estimated Alabama Income Tax Payments

Estimated payments can be required when withholding and credits are not expected to cover enough of the taxpayer's annual Alabama liability. This commonly affects self-employed people, business owners and taxpayers with substantial income that is not subject to wage withholding.

Alabama generally requires estimated payments when the taxpayer expects to owe at least $500 after withholding and credits plus expects those prepayments to be less than the smaller of 90 percent of the current-year tax or 100 percent of the prior-year tax, assuming the prior return covered a full year.

Calendar-year estimated payment dates generally fall on April 15, June 15, September 15 and January 15.

When Is the Alabama Income Tax Return Due?

Alabama individual income tax returns are generally due on the same date as the corresponding federal individual return, which is April 15 for most calendar-year taxpayers. If the date falls on a weekend or state holiday, the deadline moves to the next business day.

Alabama provides an automatic six-month filing extension to October 15. The extension applies to filing time, not the payment deadline. Tax expected to be due should still be paid by the original deadline to reduce interest and late-payment penalties.

Alabama State Tax Refunds and Withholding Reconciliation

An Alabama refund can result when payments and credits exceed the final state income tax liability. Wage withholding reported on Form W-2 is one common source of prepaid Alabama tax.

A refund is not proof that the withholding calculation was optimal. It simply means the taxpayer paid more through withholding, estimated payments or refundable credits than the final liability shown on the return. Taxpayers can track Alabama refund information through the state's tax system after filing.

Alabama Income Tax and Payroll Records

Income tax return calculations and payroll records serve different purposes. The state return determines annual Alabama tax liability while a pay stub shows current-period earnings, withholding and other deductions.

After payroll values have been calculated and verified, an Alabama pay stub generator can organize genuine wages and withholding into an employee-facing record. The generated document should match actual payroll activity rather than replace the employer's tax calculation.

Businesses that need a general payroll document workflow can use the online paystub generator after the underlying earnings, deductions and payment information has been confirmed.

Methodology and Source Review

This guide reflects Alabama Department of Revenue individual income tax rules, current filing guidance, 2026 withholding instructions and the 2026 overtime premium deduction guidance available as of August 24, 2026. Tax law can change and return-specific instructions can add detail, so current Alabama forms and official guidance should control when they differ from a general explanation.
