Alabama State Income Tax Guide (2026)

Alabama's 3-bracket structure compresses immediately. The 2% bracket covers only the first $500 of taxable income. The 4% bracket runs to $3,000. Above $3,000 of taxable income, the 5% top rate applies to everything. At any salary above ~$15-$20K, the bulk of your income sits in the 5% bracket. Effective AL state rate before the federal-tax-deduction adjustment lands around 4.7-5.0% at most professional income tiers.

The federal income tax deduction is the structural feature most state-comparison rankings either miss or under-weight. Alabama is one of only 5 remaining states that allow taxpayers to deduct federal income tax paid from state taxable income — and AL's deduction is uncapped (unlike MO and MT at $5K/$10K, or OR at $8,500 with phase-out). For a $100K AL single filer paying about $14,000 federal tax, the math is: AL taxable income = $100K (gross) - $2,500 (AL standard deduction) - $14,000 (federal tax paid) = $83,500. AL tax = roughly $4,140 (against the bracket schedule). Without the federal deduction, AL tax would be about $4,840. The federal deduction saves about $700/year at this income level.

The benefit grows linearly with federal tax paid. At $200K single income with ~$36K federal tax, the federal deduction saves about $1,800/year. At $500K with ~$110K federal tax (uncapped), saves about $5,500/year. The uncapped nature is what distinguishes AL from MO/MT (both capped at $5K/$10K) and from OR (capped with phase-out). Louisiana is the only other state with a comparable uncapped federal deduction — and LA's 3% flat top rate is appreciably lower than AL's 5% anyway.

Birmingham 1% occupational tax applies to all wages earned for work performed in Birmingham city limits — residents and non-residents alike. Most other AL cities (Huntsville, Mobile, Tuscaloosa, Auburn, Montgomery, Decatur, Florence) have no local income tax. Suburban Birmingham (Hoover, Vestavia Hills, Mountain Brook, Homewood, Helena, Trussville, Pelham) all skip the city tax — saves about $1,000/year on a $100K salary for non-Birmingham-city workers.

Alabama's economy is appreciably more diverse than its low-tax-Southeast reputation suggests. Auto manufacturing anchors central Alabama: Mercedes-Benz Tuscaloosa (the German automaker's largest US plant), Honda Lincoln (in Talladega County, the largest Honda plant in North America), Hyundai Montgomery, Toyota-Mazda Manufacturing Huntsville (a more recent joint-venture plant). Combined, AL is the #4 US auto-producing state behind MI, OH, and IN. Auto-supplier roles command competitive professional engineering wages typically in the $80K-$130K range.

Huntsville is one of the more underrated aerospace and defense employment clusters in the country. NASA Marshall Space Flight Center (the main NASA propulsion development center), Redstone Arsenal (Army Materiel Command, Aviation and Missile Command), Boeing Defense, Lockheed Martin Missiles and Fire Control, Northrop Grumman, Raytheon, plus dozens of defense contractors and engineering consulting firms. Security-clearance-required engineering and program management roles in the $100K-$180K range are common. Huntsville housing remains genuinely affordable for a metro of its growing economic depth (median home ~$320K, Madison suburb ~$420K).

Birmingham anchors healthcare and finance: UAB Health System, Regions Financial HQ, Blue Cross Blue Shield of Alabama, Children's of Alabama, Drummond Company. Mobile anchors maritime and aerospace — Airbus Mobile (final assembly for A220 and A320 family aircraft), Austal USA shipbuilder, Port of Mobile. Auburn and Tuscaloosa are college-town economies. The AL economy supports a professional workforce that's genuinely well-paid for the cost-of-living context.

Four scenarios that cover most readers. Find the one closest to you. If none match, the calculator at the top is for you.

Alabama property tax effective statewide average is about 0.41% on market value — third-lowest in the country behind Hawaii (~0.30%) and Colorado (~0.51%, though some sources rank CO and AL similarly). For context, the national average is about 1.10%. A $300K Alabama primary residence pays roughly $1,250/year in property tax — versus $3,300 in TX, $4,200 in IL, $5,400 in NJ. The structural reason: AL's state-level constitution caps property tax assessment ratios at lower levels than peer states, and the state has historically funded public services through sales tax and other sources rather than property tax.

Approximate effective rates by county on a primary residence: Jefferson (Birmingham) 0.40-0.55%, Madison (Huntsville) 0.30-0.45%, Tuscaloosa 0.40-0.55%, Mobile 0.45-0.60%, Montgomery 0.40-0.55%, Lee (Auburn) 0.35-0.50%, Baldwin (Gulf Coast) 0.40-0.55%. Among the very lowest in the country across every county.

AL offers a Homestead Exemption (Senior — age 65+ or disabled, with income tests) that further reduces taxable value on primary residences. The combination of low effective rates plus homestead exemption makes AL one of the friendliest property tax states for both working homeowners and retirees. The structural reason for retiree migration from higher-property-tax states (NJ, NY, IL, OH) to AL is appreciable beyond just the low income tax.

No state real estate transfer tax beyond a small recording fee. The OBBBA SALT cap raise to $25K softens the deductibility hit on annual property tax, though at AL's very low effective rates, most filers don't approach the cap on property tax alone.

If you're earning $100K+ in AL and you're not doing most of these, you may be leaving real money on the table. None of this is exotic. Most of it is 30 minutes of setup once a year and discipline the rest of the year.

Alabama is the underrated low-tax winner of the Southeast for working professionals. The combination of 5% top rate (effective ~4.1% after the uncapped federal tax deduction), third-lowest property tax in the country (~0.41% effective), cheap housing, diverse economy spanning auto manufacturing + aerospace + defense + healthcare + finance, and no state estate tax makes Alabama appreciably more favorable than its headline rate suggests. The structural offset is the high sales tax stack (9-11.5% combined) and the Birmingham 1% occupational tax for city residents and workers.

Run your numbers in the calculator above. The AL state line includes the uncapped federal income tax deduction modeled per v394 — so the AL number you see is the effective post-deduction amount, appreciably lower than the headline 5% suggests.

Add 1% Birmingham occupational tax manually if you live or work in Birmingham city limits. Most other AL cities (Huntsville, Mobile, Tuscaloosa, Auburn, Montgomery) have no local income tax.

Max your 401(k) — at AL's combined ~26-31% effective rate (federal + state after deduction), every pre-tax dollar saves $260-$310 of total tax per $1,000 contributed. If you have kids, contribute to AL CollegeCounts 529 to capture the state-tax deduction. If you're 65+ or disabled, apply for the Homestead Exemption with your county tax assessor.
