Alabama Payroll Calculator: Taxes, Withholding and Deductions
An Alabama payroll calculator or Alabama paycheck tax calculator should account for both federal payroll taxes and Alabama's own withholding rules. Federal income-tax withholding is based primarily on Form W-4. Alabama withholding uses the separate Form A-4 and a state formula that annualizes wages before applying the applicable standard deduction, federal income-tax withholding, personal exemption, dependent exemption and Alabama tax brackets. After estimating the paycheck, use our pay stub generator when you need to turn the wage, tax and deduction figures into a payroll document.
At lower income levels, Alabama's withholding standard deduction starts at $3,000 for Single, $4,250 for Married Filing Separately, $5,200 for Head of Family and $8,500 for Married Filing Jointly, then phases down to $2,500 (or $5,000 for Married Filing Jointly) as annualized income increases. Form A-4 exemption status also matters: the withholding tables recognize zero exemption, Single, Married Filing Separately, Married and Head of Family elections, each with its own personal exemption.
Why Alabama Subtracts Federal Tax Before State Tax
Alabama is one of only a handful of states that allows a deduction for federal income tax, and its withholding formula follows the same rule. (Our guide to how much federal tax should be withheld in 2026 covers the federal side.) That has three practical effects on your paycheck. First, your effective Alabama rate is lower than the 5% headline: for the Single salaries in the tables above, it lands around 3.9% to 4.2% of gross pay. Second, anything that changes your federal withholding also nudges your Alabama withholding in the other direction: claiming the child tax credit in W-4 Step 3 lowers federal tax, which raises Alabama taxable income slightly. Third, extra federal withholding you request in W-4 Step 4(c) reduces the Alabama amount a little, and so does anything that raises federal withholding, while W-4 Step 4(b) deductions lower federal withholding and nudge Alabama up. It's a small interaction, but it's why two Alabama employees with the same salary can see different state withholding.
Alabama Withholding Calculator and Form A-4
Alabama Form A-4 is not interchangeable with federal Form W-4. The Alabama Department of Revenue instructs employers to obtain a completed A-4 from employees whose wages are subject to Alabama withholding. If an employee doesn't furnish Form A-4, Alabama instructs the employer to withhold using zero exemptions, which means no personal exemption and the highest withholding. If your Alabama withholding looks too high, a missing A-4 is the first thing to check.
The calculator's Alabama section lets you choose the A-4 exemption status, enter dependents and add extra Alabama withholding per paycheck. That makes it useful as an Alabama income tax calculator or Alabama withholding calculator when you want to see how a different A-4 election changes net pay.
Alabama Hourly Paycheck Calculator
The same tax calculation works for hourly pay. Enter the hourly rate, regular hours and overtime hours for the pay period, then select weekly, biweekly, semimonthly or monthly payroll. The Alabama hourly paycheck calculator also works as an Alabama hourly pay calculator, converting those earnings into gross pay before applying federal tax, FICA, Alabama withholding and deductions. If you are comparing annual salary with hourly compensation, use our salary-to-hourly calculator.
For example, an employee earning $20 per hour for 40 regular hours has $800 of regular gross pay before taxes and deductions. If overtime hours are entered, the calculator adds the overtime amount to gross wages before calculating the paycheck deductions. When you need a finished wage statement, our online pay stub generator can use the same payroll figures.
Alabama Overtime Pay and Taxes in 2026
Alabama's earlier paycheck-level overtime exemption ended in 2025. For calendar years 2026 through 2028, Alabama instead allows qualifying taxpayers to deduct the premium portion of overtime on the state income-tax return, limited to the lesser of the actual premium or $1,000 per taxpayer. Alabama Department of Revenue guidance states that this reporting does not change wages, withholding or taxes on Form W-2, so this paycheck calculator continues to treat current overtime wages as payroll wages when estimating withholding. For the federal side of the same question, see why overtime is still taxed on your 2026 paycheck.
Alabama Tax on Bonuses and Supplemental Pay
Bonuses, commissions paid separately and other supplemental wages can be withheld at flat rates. Alabama allows employers to withhold state tax on supplemental wages at 5%, and federal supplemental withholding is usually a flat 22%. On a $5,000 bonus, that's $1,100 federal, $310 Social Security, $72.50 Medicare and $250 Alabama tax, leaving $3,267.50. If you work in Birmingham, the 1% occupational tax takes another $50. The bonus is still ordinary income when you file, so the flat rates are withholding, not your final tax. Employers can also combine the bonus with regular wages and use the normal formula, which can produce a different number.
Working Across State Lines
Alabama doesn't have reciprocal agreements with any state. Alabama residents are taxed on all their income, so if you live in Alabama and work in Georgia or Mississippi, you'll usually have that state's tax withheld and then claim a credit on your Alabama return for tax paid to the other state. Florida and Tennessee don't tax wages, so Alabama residents working there generally still owe Alabama tax and may want to ask the employer to withhold it or add extra withholding themselves.
Nonresidents who work in Alabama owe Alabama tax on wages for work performed in the state. Starting in 2026, a 30-day safe harbor applies: an out-of-state employee who works in Alabama for 30 days or fewer during the year isn't subject to Alabama withholding, and the employer keeps withholding for the home state until the 31st day.
Alabama Minimum Wage and Overtime Rules
Alabama has no state minimum wage or overtime law, so covered employers follow the federal Fair Labor Standards Act. That means a minimum wage of $7.25 per hour and overtime of at least 1.5 times the regular rate for hours over 40 in a workweek for nonexempt employees. At $7.25 an hour for 40 hours, weekly gross pay is $290 before taxes.
Local Occupational Taxes in Alabama
Some Alabama work locations have a local occupational tax, usually 0.5% to 2% of wages. These taxes aren't administered by the Alabama Department of Revenue, so the city or county collects them under its own rules. They're generally tied to where the work is physically performed, so a remote employee working from home outside city limits usually isn't subject to the tax even if the employer's office is in the city. The calculator leaves the local rate at 0% by default. See the city-by-city table below and enter the rate that applies to your work location.
Employer Payroll Costs in Alabama
Some Alabama payroll costs never show up as employee deductions. Employers pay state unemployment insurance on the first $8,000 of each employee's annual wages, with new employers generally starting at 2.7%. They also pay the employer share of Social Security and Medicare and federal unemployment tax. Alabama withholding is reported on Form A-1 (quarterly) or Form A-6 (monthly for larger withholders), and the annual Form A-3 reconciliation and employee W-2s are due January 31. When year-end comes, our W-2 form generator can use the same wage and withholding totals.
Why Your Actual Alabama Paycheck May Differ
This calculator is a close estimate, not a copy of your employer's payroll run. Year-to-date wages, benefit elections, whether pre-tax deductions reduce the local occupational tax base, rounding by pay period and a 27th biweekly payday in some years can all move the result by a few dollars. If the gap is bigger than that, compare your Form A-4 status, dependents and extra withholding with what's on file with your employer.
Paycheck planning tip:
Form W-4 controls federal withholding and Form A-4 controls Alabama withholding. Updating one form doesn't automatically update the other. Use the
Form W-4 tool
when you need the federal form, then review the Alabama A-4 information used by your employer.
