Alabama Payroll Taxes and Withholding Guide (2026)

What Makes Alabama Payroll Different

Federal payroll tax is the same in every state. What changes from one state to the next is the second layer: state income tax withholding, employer unemployment taxes, and any local wage taxes. Alabama has two features that set it apart. First, its withholding formula subtracts the employee's own federal income tax before the state rate is applied, one of only a handful of states that allow a federal income tax deduction. Second, its local wage tax reaches only the roughly two dozen cities that adopted an occupational tax, rather than the whole state.

Alabama's graduated rate tops out at only 5%, and because the standard deduction, personal exemption, dependent allowances, and the federal tax are all subtracted first, the effective rate most workers see is well below 5%. The federal baseline behind all of this is explained in the how payroll taxes work guide.

Employee Withholding Overview in Alabama

An Alabama employee sees federal taxes and a graduated state tax, plus a city occupational tax if they work in one of the occupational-tax cities. There is no employee unemployment line and no state disability line.

The federal lines work identically to any other state. For Social Security, the 2026 wage base is $184,500, after which Social Security stops for the year. Medicare has no cap. What is unique to Alabama is that the state line is graduated but capped at 5%, subtracts the federal income tax first, and the occupational tax appears only for workers in the cities that levy it, with no employee unemployment contribution at all.

How Is Alabama State Income Tax Withheld?

Alabama uses the formula method in the Alabama Department of Revenue's Withholding Tax Tables and Instructions for Employers. The employer annualizes wages, then subtracts four deductions before applying the graduated rate: the income-phased standard deduction, the employee's own annual federal income tax withheld, the A-4 personal exemption, and per-dependent allowances. The graduated rate below applies to what remains.

The federal Form W-4 sets federal withholding, covered in the W-4 withholding explained guide, while Form A-4 sets the Alabama exemption status and any additional Alabama amount. Because Alabama subtracts your federal income tax, the federal figure and the Alabama figure move together: raising your federal withholding lowers your Alabama base.

Alabama Withholding (Form A-4)

Form A-4 is Alabama's employee withholding exemption certificate, and the federal W-4 is not an acceptable substitute. It sets an exemption status that drives the standard deduction, the personal exemption, and the rate schedule, plus the number of dependents and any additional Alabama amount.

A-4 Status and Deductions

The standard deduction is a maximum that phases down as gross income rises, floored between $2,500 and $5,000 depending on status. Each dependent claimed on the A-4 is worth $1,000 (gross income $50,000 or less), $500 ($50,000 to $100,000), or $300 (over $100,000). If no A-4 is filed, the employer withholds at "0" with no personal exemption, so more of the pay is taxed. To see how status, dependents, and the federal tax deduction change take-home pay, use the Alabama paycheck calculator.

The Federal Income Tax Deduction

This is the feature that defines Alabama payroll. Alabama is one of a small number of states that allow a deduction for federal income taxes. In the withholding formula (Line 2B), the employee's annual federal income tax withheld is subtracted from the wage base before the state rate is applied.

The practical effect is counter-intuitive: two Alabama workers with the same gross wages but different federal withholding will have different Alabama tax, and the one who withholds more federal tax owes less Alabama tax. It also means the calculator's Alabama figure depends on the federal figure it computes, so an accurate federal W-4 entry produces an accurate Alabama line. On the annual return, Alabama likewise allows a deduction for federal income tax paid.

Alabama City Occupational Taxes

About two dozen Alabama municipalities levy an occupational or license tax on wages earned within the city. Unlike the state income tax, which is charged after the deductions, the occupational tax rides on gross wages.

Employers withhold the occupational tax and remit it to the city. Because it is charged on gross wages, a traditional 401(k) deferral does not reduce it, though a Section 125 cafeteria-plan premium does because it lowers Medicare wages. The tax follows where the work is physically performed, so a commuter into Birmingham pays it while a Birmingham resident working elsewhere does not. Other cities with occupational taxes include Attalla, Rainbow City, Glencoe, Midfield, Fairfield, and Leeds; rates and coverage can change, so confirm with your city. The Alabama paycheck calculator adds the line when you select a city.

Employer Payroll Obligations in Alabama

Alabama employers carry the federal employer taxes plus State Unemployment Insurance through the Alabama Department of Labor. The federal side, covered in the employer payroll tax obligations guide, includes the matching 6.2% Social Security and 1.45% Medicare plus Federal Unemployment Tax (FUTA). On top of that, Alabama adds the employer unemployment contribution. There is no employee unemployment contribution to withhold.

The Alabama unemployment taxable wage base is $8,000 per employee, so the employer unemployment tax stops once an employee's year-to-date wages pass $8,000. New employers pay a 2.7% entry rate before moving to an experience-rated rate between 0.20% and 6.80%; these are employer costs and are never deducted from employee pay. Employers with workers in an occupational-tax city also register with the city to withhold and remit the tax. Model the combined cost-to-hire with the employer payroll tax calculator.

Alabama Has No Employee Unemployment Deduction

A handful of states, including Pennsylvania and New Jersey, take a small unemployment contribution directly from employee wages. Alabama is not one of them. The entire cost of Alabama unemployment insurance falls on employers through the Alabama Department of Labor, so there is no employee unemployment line on an Alabama pay stub at all.

This matters most for workers who move to Alabama from a state that does deduct employee unemployment and expect to see the same line. In Alabama that line simply does not exist, and its absence is correct, not a payroll error. Alabama also has no state-run disability insurance deduction and no paid-family-leave payroll deduction, so the mandatory deductions on an Alabama stub are federal taxes, the graduated state income tax, and, in occupational-tax cities, the city tax.

Alabama Supplemental Wage Withholding

Supplemental wages are payments outside regular salary: bonuses, commissions, overtime, sales awards, and back pay. Alabama sets a simple rule on the state line.

• Flat method: Alabama employers may withhold state income tax on bonuses and supplemental wage payments at a flat 5%, per the withholding booklet.
• Aggregate method: add the supplemental wages to regular wages and run the combined amount through the standard A-4 formula.
• Occupational tax: the city occupational tax applies to supplemental wages the same as to regular wages, on gross.
• Employee unemployment: none, on supplemental wages or regular wages.

Federal income tax withholding on supplemental wages is a separate calculation set by the IRS, and Social Security and Medicare still apply under their own rules. For the federal supplemental math, use the Bonus Tax Calculator.

Alabama Filing and Payment Frequency

Alabama employers report and remit withheld state income tax on a monthly or quarterly schedule based on the amount withheld, using Form A-1 (quarterly) or Form A-6 (monthly), and reconcile annually on Form A-3 with the W-2 information by the end of January. A single withholding payment of $750 or more must be filed and paid electronically. The Alabama Department of Revenue's withholding booklet sets out the deposit schedule and the withholding tables. The federal deposit schedule is covered separately in the payroll tax deadlines guide.

Unemployment tax is reported and paid separately from income tax withholding, on a quarterly basis through the Alabama Department of Labor. City occupational tax is remitted to the city on its own schedule. New employees must be reported to the Alabama new-hire directory.

How Take-Home Pay Works in Alabama

The calculation sequence runs from gross pay down to net pay. The distinctive step is subtracting the federal income tax from the Alabama base, so the federal line has to be computed before the Alabama line.

1. Start with gross wages for the pay period.
2. Subtract federal pre-tax deductions (401(k), Section 125 health premiums) to find taxable wages.
3. Apply federal income tax withholding using the Form W-4 and IRS Publication 15-T.
4. For the Alabama line, subtract the standard deduction, the A-4 personal exemption, dependents, and the annual federal income tax withheld, then apply the graduated 2%/4%/5% rate.
5. If the work city has an occupational tax, apply its rate to gross wages (less Section 125 medical).
6. Subtract Social Security (6.2%) and Medicare (1.45%) on FICA wages (gross less Section 125 medical). The remainder is net pay; there is no employee unemployment line.

To see exact figures for a specific salary, A-4 status, dependents, work city, and pay frequency, use the Alabama paycheck calculator or the general take-home pay calculator for a full pre-tax benefits stack.
