Alabama Tax Residency Rules 2026: Domicile Test & 7-Month Rule

Who needs to read this

Alabama taxes its residents on worldwide income and, unusually, decides who is a resident almost entirely on domicile, a test with no day count and a long memory. The details below matter if:

• You're leaving Alabama for Florida, Tennessee, or Texas and want the move to actually stick
• You moved abroad from Alabama (expats are the classic Alabama residency trap)
• You split time between Alabama and a second home elsewhere
• You recently moved in and keep a home or job in another state
• You're a remote worker with an Alabama employer or Alabama clients

How Alabama defines residency

Alabama's test is domicile first. Under the Department of Revenue's rules (Ala. Admin. Code r. 810-3-2-.01), individuals domiciled in Alabama are taxable on their entire income "whether earned within or without Alabama", and that is true regardless of physical presence in the state at any time during the year.

For people domiciled elsewhere, there is a presumption: individuals not domiciled in Alabama "who maintain a permanent place of abode within Alabama, or who spend more than a total of seven months (whether or not consecutive) of the taxable year within Alabama shall be presumed to be residents."

So there are two ways in:

1. Domicile: Alabama is your one true home, no matter where you are this year.
2. The 7-month / abode presumption: you belong to another state on paper, but you keep an Alabama home or spend most of the year there.

There is no 183-day bright line, and no day count that protects a domiciliary.

Counting the days

Days matter mainly for the non-domiciliary presumption:

• The seven months are counted in aggregate; the rule says "whether or not consecutive," so scattered stays add up.
• Alabama publishes no part-day or travel-day carve-outs, so treat any day with a foothold in the state as one that could count against you.
• For domiciliaries, days are still evidence: where you actually spend the year is one of the strongest facts in any domicile dispute, and the burden of proving your whereabouts is yours. A contemporaneous day log (this is exactly what iReside tracks) is far more persuasive than a reconstruction from old calendars.

Domicile: the stickier test

Alabama's own definition: domicile is "where one lives, has a permanent home, and has the intention of returning when absent." It can arise by birth, choice, or operation of law, and each person has one and only one domicile, which, once established, "continues until a new one is established coupled with the abandonment of the old."

Two features make Alabama's version unusually sticky:

• A temporary absence changes nothing. Years working out of state (or out of the country) do not end Alabama domicile by themselves.
• The burden of proof is on you, "even though he/she owns no property, earns no income, and has no place of abode in Alabama." Selling everything and leaving is not enough; you must land somewhere new with the intent to stay.

Expect the state to weigh the usual connections: where your home and family are, driver's license, voter and vehicle registration, business and professional ties, and the address on your federal returns.

Part-year residents and nonresidents

The move year splits your filing: resident-period income goes on Form 40, and Alabama-source income earned while a nonresident goes on Form 40NR.

• Part-year residents file Form 40 and report only income earned while an Alabama resident. Itemized deductions and the federal income tax deduction are prorated to the residency period; the standard deduction and personal/dependent exemptions are allowed in full.
• Nonresidents with Alabama-source income, including pay for services performed in Alabama, file Form 40NR once Alabama gross income exceeds the prorated personal exemption.
• Moved mid-year and earned Alabama-source income during the nonresident months? You file both Form 40 and Form 40NR for the same year, splitting income and deductions between the residency and nonresidency periods (exemptions go on the part-year return only).

Alabama-source income that follows you after you leave includes income from Alabama property and businesses and compensation for work physically performed in the state.

Changing your residency status

Because domicile controls, leaving Alabama is about proving a new permanent home, not counting days:

• Establish a real home in the new state and actually live there; Alabama domicile survives until a new one is established and the old one abandoned
• Move the family, not just yourself; a spouse and homestead left behind anchor domicile
• Flip the paper trail promptly: driver's license, voter and vehicle registration, homestead exemptions, professional licenses, mailing addresses, and the address on your federal return
• Give up the Alabama abode, or at least stop maintaining it as an always-available home; remember the separate presumption for non-domiciliaries who keep one
• Keep your Alabama days modest and documented, especially in the move year
• Moving abroad? Establish domicile in a specific foreign place (or a new state first); "gone but not landed" is exactly the pattern Alabama wins on

How Alabama enforces its rules

Alabama's audit posture is less industrialized than California's or New York's, but the legal deck is stacked in the state's favor:

• The burden of proof on a change of domicile sits entirely on the taxpayer: the state doesn't have to prove you stayed; you have to prove you left
• Domicile continues by default, so the Department can assert residency years after a sloppy move, particularly against expats and retirees with lingering Alabama ties
• Expect scrutiny of the usual records: property and homestead filings, voter and vehicle registration, license renewals, and the addresses on federal returns
• Stakes compound quietly: back tax at 5% on worldwide income plus interest and penalties across multiple unfiled years

Common mistakes

• Assuming 183 days is the rule. Alabama has no such line; a domiciliary can spend zero days in the state and still owe tax on everything.
• Moving abroad without landing anywhere. Expats who abandon Alabama but never establish a new domicile remain Alabama residents by default.
• Keeping a permanent Alabama abode while "living" elsewhere. For non-domiciliaries it triggers the residency presumption on its own.
• Ignoring the seven-month clock. Scattered visits count in aggregate; snowbird patterns can quietly cross it.
• Comparing rates without the federal deduction. Alabama's 5% top rate overstates the true burden because federal income tax is deductible on the state return, so do the math before assuming a move saves what you think.
• Filing the wrong move-year forms. Part-year residents use Form 40; add Form 40NR only if you had Alabama-source income while a nonresident. Mixing the two invites questions.
