Key takeaways
- Alabama employers must withhold state income tax at graduated rates of 2–5%, contribute to state unemployment insurance on the first $8,000 of each worker's wages, and carry workers' compensation coverage once they have five or more employees.
- Alabama Act 2025-334 introduced a significant 30-day safe harbor rule for nonresident workers that changes withholding obligations for employers with multi-state staff.
- Deel Payroll automatically calculates Alabama withholding and immediately applies regulatory updates to its processes, so you stay compliant without managing it manually.
Hiring in Alabama means navigating a state tax system that's more layered than it first appears. You're responsible for withholding state income tax, paying unemployment insurance, and meeting quarterly filing deadlines. And a new rule introduced in 2025 changed how nonresident workers are taxed when they work in Alabama for part of the year.
This guide covers every Alabama payroll tax obligation employers need to know. For a state-by-state overview, see how US state payroll taxes vary.

Federal payroll taxes that apply in Alabama
Before covering state-specific obligations, it's worth confirming the federal taxes that apply to all Alabama employers.
FICA (Social Security and Medicare)
- Social Security: 6.2% on the first $184,500 of wages per employee in 2026, up to a maximum of $11,439 per employee (employer matches employee contribution)
- Medicare: 1.45% on all wages; an additional 0.9% applies to employee wages above $200,000 (employer-only matching rate is 1.45%)
FUTA (Federal Unemployment Tax Act)
- 6% on the first $7,000 of each employee's wages
- Employers who pay Alabama SUI in full and on time receive a credit of up to 5.4%, reducing the effective FUTA rate to 0.6%
File federal payroll taxes for US employers using Form 941 (quarterly) and Form 940 (annual FUTA), and remit via the IRS's EFTPS system.
Alabama state income tax withholding
Alabama requires employers to withhold state income tax from every employee's wages and remit those amounts to the Alabama Department of Revenue (ALDOR). The employer does not pay this tax. Instead, you collect and remit it on the employee's behalf.
Tax brackets and rates
Alabama uses a three-bracket progressive structure. The brackets differ by filing status:
Single filers, Head of Family, and Married Filing Separately
| Taxable income | Rate |
|---|---|
| First $500 | 2% |
| Next $2,500 ($500–$3,000) | 4% |
| Over $3,000 | 5% |
Married Filing Jointly
| Taxable income | Rate |
|---|---|
| First $1,000 | 2% |
| Next $5,000 ($1,000–$6,000) | 4% |
| Over $6,000 | 5% |
Source: ALDOR Withholding Tax Tables and Instructions for Employers, Revised January 2026.
Because the thresholds are low, most employees have at least a portion of their wages taxed at the 5% rate. However, Alabama's unique allowance for deducting federal income taxes paid from state taxable income meaningfully reduces the effective rate for most workers.

Alabama Form A-4 (employee withholding certificate)
Employees must complete Form A-4, not the federal W-4. If an employee fails to provide a completed Form A-4, withhold at zero exemptions until they do. Employers should retain all employee exemption certificates for at least three years.
Personal exemptions under Form A-4:
- Single (S): $1,500
- Married Filing Separately (MS): $1,500
- Married Filing Jointly (M): $3,000
- Head of Family (H): $3,000
- Dependents: $1,000 each (if gross income ≤ $50,000), $500 each ($50,001–$100,000), $300 each (above $100,000)
Standard deductions
The standard deduction is not a flat amount. Instead, it phases out as income rises:
| Filing status | Gross income | Standard deduction |
|---|---|---|
| Single (S) | $25,999 or less | $3,000 |
| Single (S) | $25,999–$35,499 (phases out) | $3,000 → $2,500 |
| Single (S) | $35,500 and above | $2,500 |
| Married (M) | $25,999 or less | $8,500 |
| Married (M) | $25,999–$35,499 (phases out) | $8,500 → $5,000 |
| Married (M) | $35,500 and above | $5,000 |
| Head of Family (H) | $25,999 or less | $5,200 |
| Head of Family (H) | $35,500 and above | $2,500 |
| Married Filing Separately (MS) | $12,999 or less | $4,250 |
| Married Filing Separately (MS) | $17,750 and above | $2,500 |
Supplemental wages
Employers may withhold Alabama income tax from bonuses and supplemental wages at a flat rate of 5%.
Key income exemptions
The following income types are exempt from Alabama state income tax and should not be included in wages subject to withholding. Note that pre-tax payroll deductions, such as 401(k) and Section 125 contributions, reduce the wage base before withholding is calculated:
- Social Security benefits
- Most pension and retirement income (state employee, teacher, military, and federal railroad pensions are fully exempt)
- Military retirement pay
- IRA and 401(k) distributions
- Severance pay up to $50,000 (with prior ALDOR approval)
- 403(b) and 457 plan contributions (pre-tax)
Compliance
How to compute Alabama withholding
ALDOR provides two methods for calculating Alabama withholding taxes:
1. Withholding tables (for manual calculation)
2. The formula method (required for payroll software and for employees with dependents or wages exceeding the table ranges)
See our guide on how payroll tax withholding works for more information.
Formula method (abbreviated):
- Annualize the employee's gross wages for the pay period
- Subtract: Standard deduction + federal income tax withheld (annualized) + personal exemption + dependent allowances
- Apply the applicable tax rate brackets to the remaining taxable amount
- Divide the annual tax by the number of pay periods to get the per-period withholding
The full withholding tables are published in ALDOR's Withholding Tax Tables and Instructions for Employers and Withholding Agents (Revised January 2026), available at revenue.alabama.gov.
2026 Alabama payroll update: The 30-day safe harbor rule
The most significant change affecting Alabama payroll compliance in 2026 is Act 2025-334. Enacted in 2025 and effective for tax year 2026, it created a 30-day safe harbor rule for nonresident workers who perform services in Alabama.
What the rule does
Nonresident employees who work in Alabama for 30 or fewer days in a calendar year are exempt from Alabama income tax on those earnings, and employers have no Alabama withholding obligation for those days.
Qualifying conditions
To qualify for the safe harbor, all three of the following must be true:
- The nonresident performs duties in Alabama for 30 or fewer days during the calendar year
- The nonresident performs employment duties in more than one state during the calendar year
- The nonresident's home state has a similar exclusion, has no income tax, or the income is exempt for federal purposes
Exclusions
The safe harbor does not apply to professional athletes, professional entertainers, or public figures performing in their professional capacity.
Employer obligations
- 30 or fewer days in Alabama: No Alabama withholding. Report income and withholdings to the employee's home state (if that state has income tax)
- 31 or more days in Alabama: All income earned in Alabama during the full calendar year becomes taxable. Withhold and remit Alabama income tax on the entire amount retroactively
ALDOR will grant discretion on late penalties and interest if the 30-day threshold is exceeded unexpectedly, provided employers respond promptly.
Practical implication: Employers with workers who travel to Alabama for business, conferences, or project work should implement a time and attendance tracking system to monitor day counts by state. Crossing the 31-day threshold retroactively triggers withholding obligations on all Alabama earnings for that year. See our guide to managing multi-state payroll compliance for a full framework on tracking nexus obligations across states.
State unemployment insurance (SUI)
Alabama's state unemployment insurance (SUI) program is administered by the Alabama Department of Labor. SUI is an employer-only tax, so employers do not deduct it from employee wages.
| Detail | 2026 rate/amount |
|---|---|
| New employer rate | 2.7% (applies for at least the first two years until experience rating qualifies) |
| Experienced employer rate | 0.2%–6.8% (based on SUTA experience rating system) |
| Taxable wage base | $8,000 per employee per year |
| Maximum annual SUI per employee | $544 |
Tax rate notices: ALDOR mails rate notices to established employers no later than January 31 of each year. New employers pay the 2.7% entry rate until they have at least two complete years of measurable unemployment experience.
Filing and payment: Quarterly reports (Forms UC-CR-4 and UC-10-R) and payments are due by the last day of the month following the end of each quarter. All employers must remit SUI payments via Electronic Funds Transfer (EFT).
Manage your Alabama SUI account through the Alabama eGov portal at the Alabama Department of Labor.
FUTA credit: Paying SUI on time qualifies you for a federal FUTA tax credit of up to 5.4%, which reduces your effective FUTA rate from 6% to 0.6%.
Payroll tax filing deadlines and methods
Withholding tax (state income tax)
Alabama withholding tax is filed on either a quarterly or monthly schedule, depending on the amount withheld. These state filing schedules run alongside your federal obligations. See the quarterly federal tax return (Form 941) guide for federal deadlines that apply simultaneously.
Quarterly filers (Form A-1):
| Quarter | Period | Due date |
|---|---|---|
| Q1 | January–March | April 30 |
| Q2 | April–June | July 31 |
| Q3 | July–September | October 31 |
| Q4 | October–December | January 31 |
Monthly filers (Form A-6): Monthly filing is required if you withheld more than $1,000 in either the first or second month of a quarter. Monthly returns and payments are due by the 15th of the month following the month in which tax was withheld. Do not report more than one calendar month on a single Form A-6.
Annual reconciliation (Form A-3 + W-2s): Due by the last day of January each year. Employers submitting 10 or more W-2s, or who filed and paid electronically during the year, must file through the ALDOR website.
Electronic filing threshold
If you make a single withholding tax payment of $750 or more, you must file both the payment and the return electronically through My Alabama Taxes (MAT). Electronic filing is encouraged for all filers regardless of payment amount.
If a due date falls on a Saturday, Sunday, or legal holiday, the return and payment are due the next business day. Electronic submissions must be received by 4:00 pm on the due date.
SUI filing
Quarterly SUI reports are also due by the last day of the month following each quarter, matching the withholding tax quarterly schedule above.
Workers' compensation requirements
Unlike most states, Alabama does not require workers' compensation coverage until an employer has five or more employees in the state. Once you reach that threshold, coverage is mandatory.
Workers' compensation covers medical expenses and a portion of lost wages for employees injured on the job. Coverage must be obtained through a qualified commercial carrier. Self-insured arrangements are available for qualifying large employers under a separate application to the Alabama Department of Labor.
Global Hiring Toolkit
Local occupational taxes
Alabama allows municipalities to levy local occupational taxes on earned income. These are separate from state income tax and are collected by individual cities and counties.
Rates vary significantly by jurisdiction. Birmingham, Bessemer, and several other municipalities impose occupational taxes. These taxes are generally employer-withheld from employee wages and remitted directly to the municipality.
Important: To confirm whether your employees are subject to local occupational taxes, contact the relevant city or county government directly. ALDOR does not administer these taxes. For a state-by-state breakdown of how US state payroll taxes vary, including which states impose local-level obligations, see our full guide.
Penalties for late filing
| Violation | Penalty |
|---|---|
| Late filing of withholding return | 10% of tax due, or $50, whichever is greater |
| Late payment of withholding tax | 10% of tax due |
| Filing multiple payments/returns for the same month | $50 per occurrence |
| Electronic payment submitted without electronic return | $50 |
| Each W-2 not submitted on time | $50 per statement |
Interest also accrues on unpaid withholding tax at the rate applicable to federal tax deficiencies, which adjusts quarterly. Contact the ALDOR Withholding Tax Section at 334-242-1300 for the current rate. For a full overview of employer payroll tax obligations at both the federal and state level, see our glossary guide.
When both the return and payment are late, both penalties apply and are combined into a single figure.

For Married Filing Jointly: 2% on the first $1,000, 4% on the next $5,000, and 5% above $6,000. These rates are unchanged for 2026, per ALDOR's Withholding Tables revised January 2026.
What is the Alabama SUI taxable wage base in 2026?
The taxable wage base remains $8,000 per employee per year. New employers pay 2.7%. Established employers are rated between 0.2% and 6.8% based on their unemployment claims history, with rate notices issued by January 31 each year.
What changed in Alabama payroll tax law for 2026?
The most significant change is Act 2025-334, which introduced a 30-day safe harbor rule for nonresident workers. Employees who work in Alabama for 30 or fewer days in a calendar year are exempt from Alabama income tax on those earnings, and their employer has no Alabama withholding obligation. If the employee exceeds 30 days, all Alabama income earned during that calendar year becomes taxable retroactively.
Does Alabama have tax reciprocity agreements with other states?
No. Alabama does not have reciprocity agreements with any other state. Nonresident employees who work in Alabama must have Alabama income tax withheld on wages earned in Alabama, subject to the new 30-day safe harbor rule under Act 2025-334.
Do Alabama employers have to withhold taxes for remote employees working from home in Alabama?
Yes. If a nonresident employee works from home in Alabama, their Alabama-sourced wages are subject to Alabama income tax withholding. Track day counts carefully if the employee also works in other states.
When are Alabama withholding tax returns due?
Quarterly returns (Form A-1) are due by the last day of the month following each quarter: April 30, July 31, October 31, and January 31.

The penalty for late filing of a withholding return is 10% of the tax due or $50, whichever is greater. The penalty for late payment is also 10% of the tax due. Both penalties apply when a return and payment are both late. Interest accrues on the unpaid amount at the federal deficiency rate, which adjusts quarterly.
Does Alabama tax Social Security income?
No. Social Security benefits are fully exempt from Alabama state income tax. Military retirement pay, state employee pensions, teacher retirement income, and most other pension and retirement distributions are also exempt.
