Alabama Payroll: Employer Tax and Software Guide

Alabama looks like one of the simpler payroll states on paper. Three tax brackets that have not moved in years, no state minimum wage, no paid leave mandate, no disability insurance, and no law telling you how often to run payroll. Several states would envy that list.

Then you hit the local layer. More than two dozen Alabama municipalities levy occupational taxes on wages, the rates differ, the filing schedules differ, and the tax attaches to the physical location where the work is performed rather than where the employee lives or where your office is registered. A crew that works three job sites in a week can touch three different tax jurisdictions. Very few payroll setups handle that correctly out of the box.

Two rules also changed recently in ways most guides have not caught up with: a new overtime premium deduction took effect for 2026, bringing a fresh W-2 reporting duty, and a 30-day safe harbor for nonresident employees started in January. This guide covers what Alabama requires, what changed, and how 10 payroll providers price the work.

What Alabama requires from employers

State income tax withholding

Alabama uses three brackets, unchanged for 2026 per the Department of Revenue withholding tables revised in January.

Those thresholds are worth reading twice. A single employee reaches the top marginal rate at $3,000 of taxable income, which means effectively every full-time worker in Alabama pays 5 percent on the bulk of their wages. Personal exemptions are $1,500 for single filers and $3,000 for married. Alabama is also one of very few states that lets employees deduct federal income tax paid when computing state taxable income, a quirk written into Amendment 225 of the state constitution.

Form A-4 and the maximum-rate default

Form A-4 is the Alabama Employee's Withholding Exemption Certificate, revised April 2025. Employees must furnish it on or before the day work begins, not within a grace period afterward.

Skip it and the consequence is automatic: the employer withholds at the maximum rate with zero exemptions. For a married employee with children, that is a materially wrong paycheck from day one. Two variants cover specific cases, Form A4-MS for military spouses and Form A-4E for exempt full-time students earning under $1,800.

Filing calendar

Payments of $750 or more must be made electronically through My Alabama Taxes. Employers filing 25 or more W-2 forms must submit them electronically with the A-3.

Unemployment insurance

Unemployment insurance is employer-funded. The taxable wage base is $8,000 per employee, unchanged from 2025. New employers pay 2.7 percent, and experienced employers land between 0.20 and 6.80 percent based on claims history, plus a shared cost assessment. Rate notices go out no later than January 31 each year and are typically available in December. Coverage is triggered by paying $1,500 in wages in a calendar quarter or employing at least one worker in 20 different weeks of a year.

New hire reporting in seven days

Under Ala. Code 25-11-5(a), employers report each new hire, recall, or rehire to the Alabama Department of Labor within seven days. There is no size threshold; the obligation starts with the first employee. The penalty under Ala. Code 25-11-17 is up to $25 per violation.

What Alabama does not require

The absences matter as much as the obligations. Alabama has no state minimum wage and follows the federal $7.25, with Section 25-7-41 preempting local wage ordinances. There is no paid sick leave mandate, no paid family and medical leave program, and no state disability insurance. Alabama is also one of only three states, alongside Florida and South Carolina, with no general law governing pay frequency for private employers, and it has no statute setting a final paycheck deadline, so the federal default of the next regular payday applies. Workers compensation becomes mandatory at five or more employees, counting part-time staff.

City occupational taxes and the worksite rule

This is where Alabama payroll stops being simple, and it is the part most vendor guides skip or cover in a sentence.

Code of Alabama Section 11-51-90 lets municipalities levy occupational taxes on earned income. Birmingham created its 1 percent tax by a 5-4 city council vote in January 1964, and more than two dozen other jurisdictions have followed.

Jefferson County adds a further wrinkle by layering a county occupational tax alongside individual city taxes within its borders. Filing rhythms are not standardized: some municipalities want monthly remittance, others quarterly. Even the definition of taxable earnings varies, with some ordinances explicitly including overtime, commissions, and bonuses while others do not.

For a business with one fixed location, this is a one-time setup question. For construction, home services, healthcare staffing, or anything with crews moving between sites, it is an ongoing operational problem and the single most important thing to test during a payroll provider trial.

What changed for overtime and mobile workers

Overtime: exemption gone, deduction arrived

Alabama briefly exempted overtime wages from state income tax entirely. That exemption, created by Act 2023-421 and amended by Act 2024-437, ran from January 1, 2024 through June 30, 2025 and was not extended. Employers resumed withholding on overtime from July 1, 2025.

What replaced it is narrower and works differently. Under Act 2026-604, for calendar years 2026 through 2028, taxpayers may deduct the premium portion of overtime wages on their Alabama return, whether or not they itemize, capped at the lesser of the actual premium or $1,000 per year.

The employer-side consequence is a new W-2 reporting duty. According to the Alabama Department of Revenue, total overtime wages stay in Box 16 as state wages, while the premium portion alone goes in Box 12 using Code TT.

The premium is only the amount above base pay, the half in time and a half, not the whole overtime wage. The Box 12 entry does not change wages, withholding, or taxes on the W-2; it exists purely so the employee can claim the deduction when filing. Withholding continues normally throughout the year.

The 30-day safe harbor for nonresident employees

Act 2025-334 took effect January 1, 2026 and made Alabama the sixth state to adopt a mobile workforce safe harbor modeled on the framework drafted by the Council On State Taxation, the AICPA, and the American Payroll Association. Before it, a nonresident working a single day in Alabama triggered both a withholding obligation for the employer and a filing obligation for the employee.

The exemption applies only when all three conditions are met: duties performed in Alabama on 30 or fewer days in the calendar year, employment duties performed in more than one state that year, and a home state that either provides a substantially similar exclusion or imposes no income tax. Per the Alabama Department of Revenue, professional athletes, professional entertainers, and public figures are excluded entirely.

10 payroll providers for Alabama employers compared

Every provider below files Alabama state withholding and unemployment insurance. The differentiator here is narrower than in most states: how well the platform handles municipal occupational taxes at the address level, and whether it files the seven-day new hire report automatically.

OnPay

One plan at $49 per month plus $6 per employee, everything included, no tiers to climb. Tax filing covers all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing is in the base price. Local tax filing is supported, which matters more in Alabama than in most states.

Gusto

The most common first payroll purchase for US small businesses, with automatic tax filing, published pricing, and the best onboarding experience among payroll-first platforms. Simple runs $49 per month plus $6 per employee after a base increase in March 2026, and handles Alabama local occupational tax filing.

The constraint is that Simple covers a single state only. An employee across the line in Georgia, Tennessee, Mississippi, or Florida moves you to Plus at $80 plus $12 per employee.

Square Payroll

At $35 per month plus $6 per person, Square is the cheapest full-service option with published pricing, and the full-service plan explicitly covers federal, state, and local tax calculations, payments, and filings, plus quarterly filings and new hire reports. For an Alabama restaurant or retail operation already running Square point of sale, timecard data flows straight into payroll with no integration work.

Patriot Software

The cheapest legitimate full-service payroll on the market. Full Service is $37 per month plus $5 per employee and includes federal, state, and local tax filing plus new hire reporting. Basic is $17 plus $4 if you file taxes yourself, which in Alabama means handling A-1 quarterly returns, A-6 monthly returns where applicable, and any municipal occupational tax filings by hand.

SurePayroll

Owned by Paychex and built for very small employers and household employers. Full Service is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee. Local tax filing is the weak spot: it is available but treated as an add-on rather than standard, which is a meaningful gap in a state where a quarter of the workforce may sit inside a taxing municipality.

QuickBooks Workforce Payroll

Formerly QuickBooks Payroll. Core is $50 per month plus $6.50 per employee, and the argument for it is unchanged: if your books live in QuickBooks Online, payroll reaches the general ledger without an export. Alabama local occupational tax support is limited and generally sits on higher tiers, which is a real consideration for a Birmingham or Gadsden employer.

ADP RUN

ADP has the deepest tax compliance engine in the category, and Alabama is a state where that depth converts into real value: multi-jurisdiction local filing with address-level resolution is routine work for ADP in a way it is not for smaller platforms.

The cost is opacity. ADP does not publish RUN pricing; third-party estimates put Essential near $79 per month plus $4 per employee, but every quote is individual. Contracts typically run a year with automatic renewal and a 30 to 60 day cancellation window.

Paychex Flex

Paychex competes on service rather than software, with a named representative at higher tiers. Pricing is quote-only and quarterly administrative charges appear regularly in customer reports. In Alabama the case for it is specific: if you have staff working across several taxing municipalities and want someone to call when a city sends a notice, that access has value.

Paylocity

Paylocity sits between small-business payroll and full HCM, aimed at companies that have outgrown basic payroll. It publishes detailed state tax-facts pages including Alabama, and the HR module covers performance, learning, and engagement alongside payroll. Pricing is quote-based and implementation is a project rather than a signup.

Rippling

Rippling unifies payroll, HR, and IT provisioning on one employee record. The core platform is $35 per month plus $8 per employee, with payroll as a separate module. Real-world all-in costs land between $25 and $45 per employee per month once you assemble a working configuration.

What each provider actually costs an Alabama employer

The table below models published rates at three headcounts. Alabama borders four states, so the second-state column is worth reading even for businesses that consider themselves purely local.

Square is the cheapest published option at every headcount and includes local filings, which is an unusual combination. Patriot runs close behind but charges per additional state. The pattern that reorders everything is Gusto Simple: competitive until one hire in Georgia or Tennessee forces the Plus tier, taking a 25-person payroll from $199 to $380 per month.

Choosing a payroll provider for Alabama

Before you choose

FirstHR does not process payroll, file payroll taxes, or administer benefits. Every provider above does something we do not, and if running payroll is the problem in front of you, one of them is the answer.

What we handle is the document layer that feeds payroll: onboarding workflows, e-signatures on Form A-4, I-9s, and offer letters, employee records, and document management for 5 to 50 employee US teams at a flat $98 to $198 per month. Two of the Alabama requirements above are document problems rather than payroll problems, namely getting Form A-4 signed before day one and triggering the new hire report within seven days of hire. If those are where things break for you, that is the gap we built for.

Frequently Asked Questions

What are the Alabama payroll tax rates for employers?

Withholding runs 2 percent on the first $500 of taxable income, 4 percent on the next $2,500, and 5 percent above $3,000 for single filers, with thresholds doubled for married filing jointly. Unemployment insurance applies to the first $8,000 of wages at 2.7 percent for new employers and 0.20 to 6.80 percent for experienced ones. Alabama also allows a deduction for federal income tax paid under Amendment 225.

What is Alabama Form A-4 and what happens without it?

Form A-4 is the state equivalent of the federal W-4, revised April 2025, due on or before the day work begins. Without it the employer withholds at the maximum rate with zero exemptions. Form A4-MS covers military spouses and Form A-4E covers exempt full-time students earning under $1,800.

Which Alabama cities have an occupational tax?

Birmingham and Bessemer charge 1 percent, Gadsden charges 2 percent, and Macon County charges 1 percent. Montgomery, Opelika, Auburn, Leeds, and more than twenty other jurisdictions levy their own rates between roughly 0.5 and 2 percent, and Jefferson County adds a county tax alongside city taxes.

Is Alabama occupational tax based on where the employee lives or works?

Where the work is physically performed. An employee living outside a taxing city but working inside one owes the tax; an employee living inside one but working elsewhere generally does not. This is why Alabama requires address-level tax resolution in payroll systems rather than assignment by employer or home address.

Is overtime taxable in Alabama?

Yes. The full exemption ran from January 1, 2024 through June 30, 2025 and was not extended, so withholding on overtime resumed July 1, 2025. Act 2026-604 replaced it with a deduction for the premium portion only, capped at the lesser of the actual premium or $1,000, available for calendar years 2026 through 2028. See our overtime pay guide for how premium calculations work under federal rules.

How do employers report the overtime premium on a W-2?

Total overtime wages stay in Box 16 as state wages, and the premium portion alone goes in Box 12 with Code TT. The premium is the amount above base pay, so at $10 base and $15 overtime the premium is $5 per hour, not $15. The Box 12 entry does not change wages or withholding; it lets the employee claim the deduction.

What is the 30-day safe harbor for nonresident employees?

Under Act 2025-334, effective January 1, 2026, a nonresident is exempt from Alabama income tax and the employer from withholding when duties are performed in Alabama 30 or fewer days, the employee works in more than one state, and the home state has a similar exclusion or no income tax. At 31 days, all Alabama income for the year becomes taxable including the first 30 days. Professional athletes, entertainers, and public figures are excluded.

How long do Alabama employers have to report a new hire?

Seven days from the hire date, under Ala. Code 25-11-5(a), with no business size threshold. The penalty under Ala. Code 25-11-17 is up to $25 per violation. Reports cover new hires, recalls, and rehires and are filed with the Alabama Department of Labor.

Does Alabama require workers compensation insurance?

Yes, at five or more employees, counting full-time and part-time workers together. Below five it is optional. Alabama uses private insurers with no monopolistic state fund, so coverage is purchased on the open market or through a payroll provider offering integrated placement.
