State Residency Guide
Alabama Residency
Alabama uses a graduated individual income tax with a top marginal rate of 5.00%, reached at a comparatively low income threshold, alongside two lower brackets (2% and 4%). Alabama is unusual among the five states in this comparison for letting taxpayers deduct their full federal income tax liability from Alabama taxable income, which meaningfully lowers the effective rate for many filers.

Residency Tests
Statutory Residency Test
Alabama Administrative Code r. 810-3-2-.01 presumes an individual is an Alabama resident, even without domicile, if they maintain a permanent place of abode in Alabama and spend more than a total of seven months (not a simple 183-day count, and not required to be consecutive) in the state during the tax year. This is a materially higher bar than most 183-day states, since seven months is roughly 213 days.
Domicile Test
Alabama regulation defines domicile as the home, the fixed place of habitation, distinct from residence, which is described as a transient place of dwelling. An individual has only one domicile at a time; it continues until a new one is established and the old one is abandoned. Individuals domiciled in Alabama are taxed on worldwide income regardless of physical presence during the tax year, and the burden of proof for a change of domicile rests entirely on the taxpayer, including for federal employees and military personnel who remain presumptively Alabama residents until they prove the change.
Day Count Threshold
213 days
Any Part of a Day Rule
Not addressed with a published carve-out list; the seven-month presumption is based on cumulative months of presence with a maintained permanent place of abode rather than a strict any-part-of-a-day count, which is a materially different mechanic from the day-counting states.
Presumptions
More than seven cumulative months in Alabama during the tax year, combined with maintaining a permanent place of abode, creates a rebuttable presumption of residency even absent domicile (Ala. Admin. Code r. 810-3-2-.01).
Leaving Alabama
Practitioner commentary (Bradley Arant Boult Cummings, via the Alabama Society of CPAs) describes an increased number of residency audits by the Alabama Department of Revenue (ALDOR) in recent years, referencing a 2023 Alabama Tax Tribunal ruling on change-of-residency requirements. ALDOR commonly identifies audit targets through its information-sharing agreement with the IRS: a federal return showing an Alabama address with no corresponding Alabama state return filed, or a W-2 listing an Alabama address without a matching state filing, are the two triggers specifically named in that commentary. As with most states, the taxpayer bears the burden of proof once ALDOR or another state initiates a residency challenge.
Trailing Income
Alabama taxes Alabama-source income (wages for work performed in-state, income from Alabama businesses or property) earned by nonresidents after departure under standard nonresident-sourcing rules; no Alabama-specific deferred-compensation or stock-option clawback provision distinct from ordinary multistate sourcing was identified in this research.
Part-Year Filing
A taxpayer who terminates Alabama residency during the year must notify ALDOR of the termination and file Form 40 reporting income for the resident portion of the year; if Alabama-source income continues after departure, a nonresident return (Form 40NR) is also required for that income.
Enforcement Methods
Common Exit Mistakes
Establishing Alabama Residency
| Action | Agency | Deadline |
|---|---|---|
| Get an Alabama driver license | Alabama Law Enforcement Agency (ALEA) | within 30 days of moving to Alabama |
| Register vehicles | County License Commissioner / Alabama Department of Revenue Motor Vehicle Division | within 30 calendar days of establishing residency (Ala. Code § 40-12-262(a)) |
| Register to vote | Alabama Secretary of State | at least 15 days before an election to vote in it |
| Apply for the homestead exemption | County Tax Assessor | varies by county, generally by year-end or the county's set deadline |
Declaration of Domicile
Alabama has no formal sworn Declaration of Domicile filing like Florida's. Domicile is established through conduct and evidence: driver's license, vehicle registration, voter registration, property ownership, and where financial and family life are centered, evaluated against the regulation's requirement that a new domicile be established AND the old one abandoned.
Homestead
Alabama's homestead exemption for regular owner-occupants provides a modest exemption from state property tax; the larger benefit is age-based: homeowners 65 and older who own and occupy a single-family home get a full exemption from state property tax, with separate income-tested county exemptions (up to $5,000 of assessed value for federal AGI under $12,000, up to $2,000 for higher earners). Given Alabama's already-low 0.37% effective property tax rate, the homestead filing functions more as domicile evidence in a residency dispute than as a major dollar-value benefit compared to Florida's Save Our Homes or South Carolina's 4% assessment ratio.
Voter Registration
Register online through Alabama Interactive, by mail, or in person at the county registrar's office; the deadline to register for a given election is 15 days before Election Day (https://www.sos.alabama.gov).
Vehicle Registration Deadline
30 days
New Resident Tax Traps
New Alabama residents sometimes assume the seven-month presumption is the whole test and plan around staying under roughly 213 days; but domicile alone, established through conduct even without hitting the seven-month mark, is independently sufficient to make someone a full Alabama resident taxed on worldwide income. The other trap flows the opposite direction: filing a federal return listing an Alabama address without filing the matching Alabama state return, the specific pattern practitioners say ALDOR's IRS data-sharing agreement is now catching.
Tax Profile
Capital Gains
Taxed as ordinary income at the standard graduated rates; Alabama has no separate, lower capital gains rate.
Retirement Income
Social Security is fully exempt from Alabama tax. Defined-benefit government and qualifying private pension income (including the Teachers' Retirement System and similar defined-benefit plans) is exempt. Withdrawals from defined-contribution accounts, 401(k)s and IRAs, are taxed as ordinary income at Alabama's standard graduated rates (2% to 5%); there is no special exclusion for these account types the way some neighboring states offer.
Estate or Inheritance Tax
None. Alabama has no estate tax and no inheritance tax.
Property Tax
Alabama's effective property tax rate on owner-occupied housing is about 0.37%, one of the lowest in the country. Homeowners 65 and older who own and occupy a single-family home receive a full exemption from state property tax; county-level exemptions for seniors are separate and income-tested, up to $5,000 of assessed value for those with federal adjusted gross income under $12,000, and up to $2,000 for higher earners.
Sales Tax
4% state rate, but Alabama's local option sales taxes are among the highest in the country, pushing the average combined state-and-local rate to about 9.46%, among the top rates nationally.
Community Property
Alabama uses common law, equitable-distribution marital property rules.
Special Situations
Travel Nurses
Alabama's major hospital systems (UAB in Birmingham, Huntsville Hospital) are significant travel-nursing markets. Because Alabama's presumption threshold is a cumulative seven months rather than 183 days, a nurse needs to track total months of Alabama presence across contracts within the tax year against that higher bar, while remembering that maintaining a permanent place of abode in Alabama is a separate condition of the presumption, not an automatic trigger from days alone.
Professional Athletes
Alabama has no major-league professional sports franchise, so its jock-tax exposure runs entirely through visiting athletes and, more prominently, college athletics: NIL (name, image, likeness) income earned by student-athletes at Alabama's major programs is Alabama-source income subject to the state's standard individual income tax rates, an increasingly relevant issue as NIL payments have grown.
Remote Workers
Alabama has no convenience-of-the-employer rule. A remote worker physically performing work from Alabama for an out-of-state employer owes Alabama tax on that Alabama-source income under the state's standard sourcing rules; Alabama's full federal-income-tax deduction can meaningfully soften the effective state tax rate compared to states without that deduction.
Military
Alabama follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act, but its own regulation is notably taxpayer-unfriendly on the presumption side: federal employees and military personnel domiciled in Alabama remain presumptively Alabama residents, taxed on worldwide income, until they affirmatively prove a change of domicile, meaning a permanent change of station alone does not end Alabama tax residency without proof of genuine domicile abandonment. Alabama fully exempts military retirement pay from state income tax, a significant draw for the state's sizable veteran population given its bases (Redstone Arsenal, Maxwell-Gunter, Fort Novosel).
Students
Alabama's public universities use residency-for-tuition rules that are administered separately from tax domicile but rest on similar factors (driver's license, voter registration, financial independence, intent to remain); merely attending an Alabama university does not by itself establish tax domicile, particularly for a student who remains a dependent claimed on an out-of-state parent's return.
Snowbirds and Long Visitors
Alabama's Gulf Coast (Gulf Shores, Orange Beach) draws seasonal visitors, but the seven-month presumption is a materially higher bar than the 183-day rule used in most other states, meaning a snowbird can stay considerably longer in Alabama than they could in a 183-day state before triggering the statutory presumption, though genuine domicile-based residency remains possible even for a shorter stay if the person's conduct shows intent to make Alabama home.
Airline Crew
Alabama has a smaller commercial airline crew base than its neighbors, concentrated around Birmingham-Shuttlesworth. Federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence and, narrowly, a state where more than 50% of pay is earned; crew domiciled in Alabama are taxed on their full wages under the state's standard resident rules.
Retirees
Alabama pitches itself to retirees primarily on the combination of a full state property tax exemption for owner-occupants 65 and older, full exemption of Social Security and qualifying pension income, no estate or inheritance tax, and one of the lowest effective property tax rates in the country. The tradeoff: Alabama's combined sales tax rate, averaging about 9.46% with local surtaxes, is among the highest in the nation, and 401(k)/IRA withdrawals get no special exclusion, so the retiree tax math depends heavily on the mix between pension/Social Security income and taxable retirement account withdrawals.
Audit Profile
Statute of Limitations
No Alabama-specific deviation from the general state pattern was located in this research; Alabama generally follows a 3-year assessment period from filing, extending indefinitely where a required return was never filed for a year of claimed residency.
Typical Lookback
No hard published lookback statistics were found. Practitioner commentary (Bradley Arant Boult Cummings, published via the Alabama Society of CPAs) describes a 2023 Alabama Tax Tribunal ruling by Judge Leslie Pitman on change-of-residency requirements as instructive precedent, but the specific case name and citation could not be independently verified through a direct primary-source read in this research pass; the Alabama Tax Tribunal's own decisions archive (taxtribunal.alabama.gov/decisions/) is the authoritative place to pull it before publishing a specific case citation.
Defense Cost Range
No published figures for Alabama residency audit defense costs specifically. Given that Alabama's audit trigger pattern described by practitioners (federal-return/state-filing mismatches caught via IRS data sharing) is more mechanical and less forensic than New York's or Connecticut's cell-tower and toll-record reconstructions, informal practitioner commentary suggests these disputes typically resolve at lower cost, though no firm has published a specific dollar range.
Alabama Residency FAQ
Does Alabama use the same 183-day rule as other states?+
No. Alabama's threshold is higher: a non-domiciled individual is presumed a resident only if they maintain a permanent place of abode in Alabama AND spend more than seven cumulative months (roughly 213 days, not required to be consecutive) in the state during the tax year, which is a materially higher bar than the 183-day rule used elsewhere.
I filed my federal return with an Alabama address but didn't file an Alabama state return. Is that risky?+
Yes, practitioners specifically identify this as one of the patterns the Alabama Department of Revenue now catches through its information-sharing agreement with the IRS, along with a W-2 listing an Alabama address with no matching state filing. Both are described as active triggers for the increased number of residency audits ALDOR has been conducting.
Does Alabama tax my Social Security or pension when I retire here?+
Social Security is fully exempt, as is qualifying defined-benefit pension income (including Teachers' Retirement System and similar plans). Withdrawals from 401(k)s and IRAs, however, are taxed as ordinary income at Alabama's standard graduated rates, 2% to 5%, with no special exclusion.
I'm active duty military and Alabama was my home of record. Does a new duty station end my Alabama tax residency?+
Not automatically. Alabama's own regulation keeps federal employees and military personnel who are domiciled in Alabama presumptively Alabama residents, taxed on worldwide income, until they affirmatively prove a change of domicile. A permanent change of station alone is not enough; you need to show you genuinely established a new domicile and abandoned Alabama.
What form do I file for the year I move out of Alabama?+
Notify ALDOR of the termination of Alabama residence and file Form 40 for the portion of the year you were an Alabama resident. If you continue earning Alabama-source income as a nonresident after the move, you'll also need Form 40NR for that income.
How does Alabama's homestead exemption compare to Florida's?+
Much smaller in dollar terms because Alabama's effective property tax rate is already very low, about 0.37%. The meaningful benefit is age-based: owner-occupants 65 and older get a full state property tax exemption, with additional income-tested county exemptions. It functions more as domicile evidence in a dispute than as a major tax-savings mechanism the way Florida's Save Our Homes cap does.
Can I still be an Alabama resident even if I spend less than seven months there?+
Yes. The seven-month rule only creates a presumption of residency for people who are NOT domiciled in Alabama. If you're actually domiciled in Alabama, home, fixed place of habitation, intent to return, you're a full Alabama resident taxed on worldwide income regardless of how many months you physically spend in the state that year.
As a travel nurse, how do I count my Alabama days against the residency test?+
Track cumulative months, not just days: Alabama's non-domiciliary presumption triggers at more than seven total months of presence combined with maintaining a permanent place of abode in Alabama, a higher bar than the 183-day rule used in most other states. Back-to-back Alabama contracts can still add up to seven months faster than expected, so track it across assignments, not just within one.
How long do I have to get an Alabama driver's license and register my car after moving?+
Both are 30-day deadlines: an Alabama driver's license within 30 days of moving, and vehicle registration within 30 calendar days under Ala. Code § 40-12-262(a), which carries a $15 penalty plus interest if missed.
Does Alabama have an estate tax I need to plan around?+
No. Alabama has no estate tax and no inheritance tax, so only the federal estate tax exemption threshold matters for an Alabama domiciliary's estate.
