Moving from Washington to Alabama: Residency, Taxes, and What to Prove
The top income tax rate drops from 9.9% (phasing in 2028; no general wage income tax before then) in Washington to 5.00% in Alabama. Establishing Alabama residency correctly is what protects that benefit.
Residency Tests Side by Side
Washington uses a 183-day statutory residency threshold, while Alabama uses 213 days. Track both thresholds separately during a transition year rather than assuming they line up.
| Factor | Washington | Alabama |
|---|---|---|
| Statutory Residency Test | For the capital gains excise tax under RCW 82.87.020, a 'resident' is either (a) an individual domiciled in Washington during the taxable year, subject to a narrow safe harbor, or (b) an individual who maintained a place of abode in Washington and was physically present in the state for more than 183 days during the taxable year, regardless of domicile. Washington counts any portion of a calendar day present in the state as a full day for this 183-day count. | 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 | Washington Department of Revenue guidance and case law define domicile as residence in fact coupled with the intent to make that place your permanent home; once established, domicile continues until superseded by a new one, and the burden of proving a change falls on the person asserting it. Selling the old home or buying a new one is not, by itself, conclusive; DOR and the courts look for substantial evidence of an actual, present change, not merely a stated future intent. | 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 | 183 days | 213 days |
| Any Part of a Day Rule | Yes. Washington's capital gains tax statute treats any portion of a calendar day physically present in the state as a full day toward the 183-day count, the same aggressive counting method California uses. | 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 | None published | 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). |
| Safe Harbors | 30-day domicile safe harbor for the capital gains and Millionaires' Tax | None published |
Leaving Washington
Washington's own audit track record on personal tax residency is thin because the capital gains excise tax has only existed since 2022 and the Millionaires' Tax doesn't take effect until 2028. The clearest documented risk is around the capital gains tax: DOR has published interim guidance on domicile determination specifically because high earners have tried to time a departure around a large stock sale, and Washington courts have held the burden of proving a domicile change rests on the taxpayer, with 'substantial evidence' required, not just future intent. Expect audit intensity to rise sharply once the Millionaires' Tax begins collecting in 2029.
Trailing Income
For stock and other intangible property, Washington's capital gains excise tax follows domicile at the moment of sale, not current physical presence, so a sale executed while still domiciled in Washington remains taxable even if the closing happens after a physical move. Washington has no wage-based trailing income exposure today because there is no general wage income tax, though this changes for high earners once the 2028 Millionaires' Tax on Washington-source income takes effect.
Part-Year Filing
Washington has no general personal income tax return, so there is no part-year wage-income form. For the capital gains excise tax, Washington uses a standalone capital gains return (not integrated with a broader income tax filing) to report Washington-taxable long-term gains for the year, with residency and domicile determined separately for allocation purposes.
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.
What Changes on Tax
Washington Top Rate
9.9% (phasing in 2028; no general wage income tax before then)
Alabama Top Rate
5.00%
Moving from Washington to Alabama drops the top marginal income tax rate from about 9.9% to about 5%, a reduction of roughly 4.9 percentage points.
Withholding Reciprocity
Washington and Alabama do not have a wage-withholding reciprocity agreement with each other, so this move follows ordinary source-state and resident-state filing rules rather than a reciprocity exception.
Community Property Transition
Washington is a community property state and Alabama uses common law marital property rules. Property already characterized as community property generally keeps that character after the move, subject to the destination state's quasi-community-property treatment, while future acquisitions follow Alabama's common law rules.
Beyond Income Tax
Washington
Capital gains: Washington's capital gains excise tax (RCW 82.87) taxes long-term capital gains at 7% on the first $1 million above the annual standard deduction ($270,000 range, indexed) and 9.9% above $1 million. It exempts real estate sales entirely, gains inside qualified retirement accounts, and gains from the sale of a qualifying small business meeting ownership and revenue tests. For stock and other intangible property, the tax applies based on the seller's domicile at the time of sale, not physical presence.
Estate or inheritance tax: Washington has a state estate tax with a filing threshold and exclusion amount of $3,000,000 to $3,076,000 for decedents dying in 2026 depending on the exact date, and graduated rates up to 20%, among the highest top estate tax rates of any state. There is no separate inheritance tax.
Property tax: Effective rate is roughly 0.81% to 0.94% depending on the source and county, close to but slightly below the national average, with no broad homestead portability program comparable to California's Proposition 19.
Sales tax: 6.5% state base rate, averaging about 9.51% combined with local rates; Seattle runs around 10.35%.
Alabama
Capital gains: Taxed as ordinary income at the standard graduated rates; Alabama has no separate, lower capital gains rate.
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.
Who This Move Applies To
Travel Nurses
In Washington
Seattle-area hospital systems are a major travel nursing market. Because Washington has no general wage income tax, a genuine Washington tax home creates no state income tax exposure on stipends or wages earned in Washington, though nurses still owe nonresident tax in every other income-tax state where they take assignments. The same tax-home substantiation rules apply: an actual, regularly used residence with duplicated living expenses, not just a mailing address.
In Alabama
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
In Washington
The Seahawks, Mariners, Sounders, and Kraken are all based in Washington, and for decades Washington's lack of a personal income tax made contracts here worth more after-tax than identical contracts in California or New York, since athletes owed no state tax on the home-state portion of their income. That advantage has a hidden cost: because Washington historically had no income tax, athletes domiciled here got no tax credit to offset the jock tax other states charged them for road games, making those out-of-state payments a pure additional cost rather than an offset against home-state liability. The 2028 Millionaires' Tax will itself begin reaching a portion of highly paid athletes' income domiciled in Washington.
In Alabama
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.
Snowbirds, Long Visitors, and RVers
In Washington
The relevant test for a long-term visitor isn't Washington's general tax system, since there is none for ordinary wages, but the 183-day physical-presence-plus-abode test and the 30-day safe harbor under the capital gains excise tax. Someone who keeps a Washington vacation home and visits often needs to track their day count carefully if they have appreciated stock or other intangible property they might sell, since crossing 183 days while maintaining a Washington abode can make them a Washington resident for that tax even without ever forming domiciliary intent.
In Alabama
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.
Remote Workers
In Washington
Washington has no convenience-of-employer rule and, until 2028, no general wage income tax at all, making it one of the most attractive states for remote workers regardless of where their employer is based. The capital gains excise tax and the incoming Millionaires' Tax are the only state-level income taxes that reach a remote worker's earnings, and both turn primarily on domicile rather than employer location.
In Alabama
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
In Washington
Washington follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Naval Base Kitsap and Joint Base Lewis-McChord are major installations, and because Washington has no general wage income tax, service members and spouses electing Washington domicile under MSRRA owe no state tax on military pay or spousal wage income today.
In Alabama
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).
Airline Crew
In Washington
Seattle-Tacoma International Airport (SEA) is a major hub and crew base for Alaska Airlines and Delta. Federal law (49 U.S.C. §40116) limits taxation of air carrier employees to their state of residence and any state where they earn more than 50% of pay; because Washington has no general wage income tax, Washington-based crew owe no state tax on their wages today regardless of this federal carve-out, though the 2028 Millionaires' Tax may eventually intersect with it for the highest earners.
In Alabama
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.
Tools for This Move
Washington to Alabama FAQ
Does Washington have a state income tax?+
Not a general wage income tax, no, and that has never changed. But Washington does tax long-term capital gains above a threshold at 7% to 9.9%, has a state estate tax, and enacted a new 9.9% tax on household income over $1 million starting in 2028. So 'no income tax' is no longer the complete picture for high earners.
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.
What is Washington's Millionaires' Tax and when does it start?+
SB 6346, signed in 2026, imposes a 9.9% tax on Washington taxable income over $1 million per household, applying to residents, part-year residents, and nonresidents with Washington-source income. It takes effect January 1, 2028, with the first returns due in 2029. It faces an announced constitutional challenge and possible voter referendum, so whether it survives intact is not yet settled.
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.
Can I avoid Washington's capital gains tax just by moving out before I sell my stock?+
Only if you've actually changed your domicile before the sale, not just your address. Washington's capital gains tax sources stock and intangible property gains to your domicile at the moment of sale, and Washington courts require substantial evidence of a real, present change, not a stated future intent. Selling your Washington home or buying a new one elsewhere is not, by itself, conclusive proof you've moved.
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.
What is Washington's 30-day rule?+
It's a narrow safe harbor for people already domiciled in Washington: if you maintain no place of abode in Washington, maintain a permanent place of abode elsewhere, and spend 30 days or fewer in Washington for the entire tax year, you can be treated as a nonresident for the capital gains tax. Missing any one of the three conditions voids the whole safe harbor, and even if it applies, it changes your residency status only, not your domicile for purposes of sourcing a stock sale.
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.
Does Washington's 183-day rule work the same way as California's day count?+
Similarly, yes. Washington counts any portion of a calendar day physically present in the state as a full day toward the 183-day threshold under the capital gains tax statute, the same aggressive any-part-of-day approach California uses for its own residency analysis.
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.
Does Washington tax retirement accounts?+
No. Gains realized inside qualified retirement accounts like 401(k)s and IRAs are explicitly exempt from Washington's capital gains excise tax, and Washington has never had a general income tax on pension or retirement account distributions.
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.
