Alabama Payroll: Employer Tax and Software Guide

Alabama looks like one of the simpler payroll states on paper. I run a small company myself, and if I were setting up payroll here, the city tax layer is what I would check first, because it decides which providers file everything you owe. This guide covers what Alabama requires, what changed, and how 10 payroll providers price the work.

The state side is short: 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. Many Alabama municipalities levy occupational taxes on wages, each with its own rate and filing schedule. The tax follows the worksite, not the employee's home or your registered office, so a crew working three job sites in a week can touch three tax jurisdictions. Very few payroll setups handle that correctly out of the box.

Two state rules also changed for 2026: a new overtime premium deduction took effect, bringing a fresh W-2 reporting duty, and a 30-day safe harbor for nonresident employees began applying on January 1.

What Alabama requires from employers

Alabama payroll taxes come in three layers: state income tax withheld from wages, unemployment insurance paid by the employer, and municipal occupational taxes withheld wherever the work is physically performed. The Department of Revenue collects the first, the Department of Workforce (formerly the Department of Labor) the second, and each taxing city or county the third.

Nothing else at the state level comes out of a paycheck. Alabama has no disability program, no paid family leave premium, and no state sick leave mandate, so there is no deduction for any of them. The third layer is what makes the state harder than its bracket table looks, and it gets a section of its own below.

State income tax withholding

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

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 filers.

Alabama is also one of very few states that let 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 using zero exemptions, the setting the form itself describes as withholding at the highest rate. For a married employee with children, that is a materially wrong paycheck from day one. One variant covers a specific case: Form A4-MS, for nonresident military spouses claiming an exemption.

Filing calendar

A single payment of $750 or more must be made electronically, along with its return, through My Alabama Taxes, the Department of Revenue's online portal. Employers that submit 10 or more W-2 forms, or that filed and paid electronically during the year, 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 according to the Alabama Department of Workforce, experienced employers land between 0.20 and 6.80 percent based on claims history and on which of four rate schedules is in effect, plus any shared cost assessment.

The shared cost assessment is set each year to cover costs that cannot be assigned to a specific employer. The tax applies once you pay $1,500 in wages in a calendar quarter or employ at least one worker in 20 different weeks of a year. Employers download their annual rate notice through the agency's eGov portal.

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 Workforce, formerly the 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, so no city or county can set its own minimum wage. There is no paid sick leave mandate, no paid family and medical leave program, and no state disability insurance.

Alabama also has no general law governing pay frequency for private employers and no statute setting a final paycheck deadline. Federal law does not require immediate final pay either, according to the U.S. Department of Labor. 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. Many cities, plus Macon County, levy an occupational tax on wages, and the tax follows where the work is done, not where the employee lives. Most vendor guides skip this part or cover it in a sentence.

Municipal occupational taxes grew out of the licensing power that cities hold under Code of Alabama Section 11-51-90. Since Act 2020-14, now Section 11-51-198, a city cannot add a new one on its own; the Legislature has to authorize it by local law. Taxes already in effect before February 1, 2020 stay in place.

Jefferson County no longer adds a county layer of its own. The Alabama Supreme Court struck down its 0.45 percent occupational tax in March 2011, according to a federal payroll bulletin, so inside the county only the city taxes remain.

Filing rhythms and definitions are local too. Leeds wants monthly returns and defines taxable pay to include salaries, wages, commissions, bonuses, and severance pay, with no deductions allowed. Auburn and Opelika take quarterly returns, and Birmingham's refund affidavit, the form for reclaiming tax on work done outside the city, starts from Medicare wages.

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 a Birmingham payroll service has to handle

Birmingham is the jurisdiction that separates payroll services that genuinely handle Alabama from the ones that only claim to. The employer withholds 1 percent of compensation for work performed inside city limits and files the return with the Birmingham Tax and License Division, which since July 1, 2026 has taken tax payments only online or in person.

Around Birmingham, each city return runs on its own calendar. Bessemer wants a quarterly return by the 20th of the month after the quarter and Leeds a monthly one by the 20th, while the state A-1 is due at the end of the month after the quarter closes.

Ask any provider you are considering whether it files the city return itself or only calculates the amount and leaves the filing to you. That question also decides whether you need a local payroll bureau at all.

Birmingham payroll firms sell familiarity with the city return, and that familiarity is worth paying for only when your software cannot file it. A platform that resolves tax by worksite address and files municipal returns is already doing the work the local option is charging for.

What changed for overtime and mobile workers

Both changes land on the employer. Alabama replaced its full overtime exemption with a capped deduction that adds a reporting duty, and a safe harbor now spares nonresidents who work in the state for a limited number of days from its income tax and withholding.

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 created a mobile workforce safe harbor, an exemption for nonresidents who work in Alabama only a limited number of days, for tax years beginning on or after January 1, 2026. Before it, Alabama had no day threshold, so a nonresident who worked even briefly in the state could owe Alabama tax on that pay.

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 either a home state that provides a substantially similar exclusion or imposes no income tax, or income that federal law already exempts.

Certain workers never qualify, even when all three conditions are met. 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

OnPay sells one base plan at $49 per month plus $6 per employee; HR tools and time tracking are paid add-ons. The plan includes federal, state, and local tax filings, which matters more in Alabama than in most states. It files in all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing is in the base price.

Gusto

Gusto is a common first payroll purchase for US small businesses, with published pricing, onboarding built into the same account, and automatic tax filing: Gusto says it files federal, state, and local payroll tax forms on your behalf. Since the base price rose from $40 during 2025, Simple has cost $49 per month plus $6 per employee.

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's base fee is undercut only by SurePayroll's $29 among the published full-service plans here. Its full-service plan automates federal and state tax payments and filings and includes new hire reporting and multistate payroll. Square's Alabama tax guide lists no city occupational tax filings, though, so those returns stay with you.

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

Patriot has the lowest total cost on this list at 10, 25, and 50 employees. Full Service is $37 per month plus $5 per employee and files federal, state, and local taxes, city taxes included, while new hire reports stay with the employer.

Patriot's Basic plan is $17 per month plus $4 per employee 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

SurePayroll is owned by Paychex and built for very small employers and household employers. The Small Business plan is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee. Local taxes are the weak spot: SurePayroll charges a separate fee in areas that require them, which matters in a state where so many cities levy an occupational tax.

QuickBooks Workforce Payroll

Workforce Payroll, formerly Payroll Core, costs $50 per month plus $7 per employee, and the case for it is simple: if your books live in QuickBooks Online, payroll reaches the general ledger without an export. It files federal and state taxes only; Intuit offers certain local taxes on Workforce Premium and Elite alone, a real consideration for a Birmingham or Gadsden employer.

ADP RUN

Every ADP RUN package calculates, files, deposits, and reconciles payroll taxes, and ADP pays the resulting fines if it makes a filing error. For an Alabama employer with staff in several taxing cities, the key detail is that all four packages include multi-jurisdiction payroll, meaning more than one state or local jurisdiction in a pay period.

The cost is opacity. ADP does not publish RUN pricing, and every package (Essential, Enhanced, Complete, and HR Pro) is quoted individually. ADP says RUN needs no signed contract and the service can be ended at any time.

Paychex Flex

Paychex competes on service rather than software: the Complete package includes a payroll specialist, and the other packages offer one as an add-on. Pricing is quote-only for every package. 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 human capital management (HCM) software, aimed at companies that have outgrown basic payroll. It publishes state tax-facts pages including Alabama, prepares and files state and local withholding returns, and its HR suite 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 (laptops and app access) on one employee record. Its pricing page is a quote form, but its small-business page starts payroll plans at $8 per user per month plus a $40 monthly base fee. Its blog prices the base HR information system (HRIS) module and the payroll module at $8 per employee a month each, with payroll billed annually, so a configured quote can run higher.

The same blog estimates roughly $15 to $25 per employee per month for a 100-employee company running HRIS, payroll, benefits administration, and time and attendance.

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.

Patriot is the cheapest published option at every headcount, and its Full Service plan files local and city taxes. Square runs second and includes multistate payroll, but its plan lists federal and state filings only, so the city returns stay with you.

Gusto Simple reorders everything once you cross a state line: it stays 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

Price narrows the field, but these four questions decide it. Put each one to every provider still on your list, starting with local tax, because a wrong answer there shows up on every paycheck.

Before you choose

FirstHR is an onboarding and HR platform, not a payroll provider. To process payroll, file payroll taxes, or administer benefits, choose one of the providers above.

Payroll providers own running payroll; what we handle is the document layer around it. Onboarding workflows put the I-9, the W-4, and Form A-4 on the first-day task list of each new hire, alongside e-signatures on offer letters, employee records, and document management. That costs small and growing US teams a flat $98 a month for up to 10 people or $198 for 11 to 50.

Two of the Alabama requirements above are document and workflow problems rather than payroll problems: getting Form A-4 completed before day one and filing the new hire report within seven days of hire. If those are where things break for you, both can sit on the onboarding plan as tasks with deadlines, while the form and the report themselves are completed outside the platform.

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, plus any shared cost assessment. 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 using zero exemptions, the highest-withholding setting on the form. Form A4-MS covers nonresident military spouses claiming an exemption.

Which Alabama cities have an occupational tax?

Birmingham and Bessemer charge 1 percent, Gadsden charges 2 percent, and Macon County charges 1 percent outside areas with their own tax. Auburn, Opelika, and Leeds charge 1 percent and Irondale 0.5 percent, and since 2020 a city needs the Legislature's approval to add a new one. Jefferson County's own occupational tax was struck down in 2011.

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 payroll needs address-level tax resolution 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.

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, for tax years beginning on or after January 1, 2026, a nonresident owes no Alabama income tax, and the employer withholds none, when three conditions hold: duties in Alabama on 30 or fewer days, work in more than one state, and a home state with a similar exclusion or no income tax, or income federal law already exempts.

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 Workforce, formerly the 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.
