Moving from Ohio to Washington: Residency, Taxes, and What to Prove

Ohio's 2.75% (state, tax year 2026); municipal income taxes up to roughly 3% stack on top in most cities top income tax rate becomes 9.9% (phasing in 2028; no general wage income tax before then) in Washington. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.

Residency Tests Side by Side

Ohio does not use a simple day-count threshold; it applies a facts-and-circumstances test instead. Washington's statutory residency test uses a 183-day threshold.

FactorOhioWashington
Statutory Residency TestOhio does not use a simple day-count statutory residency test. Instead, Ohio Revised Code 5747.24 and Ohio Administrative Code 5703-7-16 create a 'bright-line' irrebuttable presumption system built around contact periods. An individual is irrebuttably presumed to be a full-year nonresident if, for the entire year, they have fewer than 213 contact periods with Ohio, maintain at least one abode outside Ohio, do not hold an Ohio driver's license, do not receive the Ohio homestead exemption, are not eligible for Ohio resident tuition rates at a state university, and timely file Form IT NRS (formerly IT DA), the Ohio Nonresident Statement, by October 15 of the following year. Fail any of those conditions and Ohio falls back to a traditional facts-and-circumstances domicile 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.
Domicile TestUnder the version of Ohio Administrative Code 5703-7-16 in effect since June 2026, the tax commissioner is barred from considering a long list of factors when weighing domicile, including where a taxpayer banks, shops, holds insurance, uses professional services, or where family members and dependents live (with a narrow schooling exception). Factors the commissioner may still weigh include the taxpayer's number of Ohio contact periods, voter registration location, prior years' tax positions, and any past failure to meet Ohio residency requirements. This is a deliberately narrower factor list than most states use, reflecting Ohio's legislative push to make the bright-line contact-period test the primary tool rather than an open-ended facts-and-circumstances inquiry.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.
Day Count ThresholdNo fixed threshold183 days
Any Part of a Day RuleOhio measures 'contact periods,' not simple days. A contact period is created when a person whose abode is outside Ohio is away from that abode overnight and spends at least part of two consecutive days in Ohio. Two contact periods can occur within the same short trip if it spans multiple overnight stays. Because the unit is a pair of consecutive days rather than a single day, Ohio's mechanics differ meaningfully from a state like New York where any part of one calendar day counts.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.
Presumptions213 contact periods is the bright-line threshold: fewer than 213 contact periods, combined with the other four bright-line conditions and a timely IT NRS filing, produces an irrebuttable presumption of Ohio nonresidency. HBK CPA and other practitioner guidance note that failing the bright-line test does not automatically make someone an Ohio resident; it simply forces the older facts-and-circumstances domicile analysis.None published

Leaving Ohio

High exit scrutiny (3/5)

Ohio is not usually named alongside New York or California as a top exit-audit state, but the Department of Taxation does actively enforce the bright-line test, and disputes concentrate on taxpayers who claim nonresidency without meeting all five conditions, most often because they missed the October 15 IT NRS deadline, still hold an Ohio driver's license, or still claim the Ohio homestead exemption on a house they call a second home. Municipal tax authorities like RITA and CCA also run their own residency inquiries independent of the state, since city income tax depends on the same kind of domicile and workday facts.

Trailing Income

Ohio does not have a broad state-level convenience-of-the-employer rule for individual income tax. The bigger trailing-tax issue is municipal: under the 20-day occasional entrant rule, an employer generally withholds municipal tax to the employee's principal place of work until the employee works more than 20 days in a different Ohio municipality in a year, after which withholding must shift. Business income and gains sourced to Ohio activity, and compensation earned for Ohio-based work before the move, remain taxable by Ohio even after departure under standard sourcing rules.

Part-Year Filing

Part-year residents and nonresidents file Ohio Form IT 1040 and attach Ohio Schedule IT NRC, the Nonresident/Part-Year Resident Credit schedule, which allocates federal adjusted gross income between Ohio-source and non-Ohio-source amounts so tax is calculated only on the Ohio-allocable share plus any Ohio-source income earned during the nonresident period.

Enforcement Methods

Ohio driver's license and BMV records
homestead exemption cross-check against the county auditor
in-state university tuition eligibility cross-check
voter registration records
contact period reconstruction from travel records, credit card statements, and utility bills
missed or late IT NRS filings flagged automatically

Common Exit Mistakes

Missing the October 15 deadline to file Form IT NRS the year after leaving, which forfeits the irrebuttable nonresident presumption for that year
Keeping an Ohio driver's license after claiming residency elsewhere, which by itself defeats the bright-line safe harbor
Continuing to claim the Ohio homestead exemption on a home the taxpayer says is now a secondary residence
Undercounting contact periods by treating a same-day trip as not triggering the two-consecutive-day contact period rule when an overnight stay was actually involved
Assuming state-level nonresidency automatically resolves municipal income tax exposure in the city where they still work

Declaration of Domicile

Washington has no formal declaration-of-domicile filing. Domicile is established through conduct and intent under the common-law standard applied in Washington Supreme Court precedent and DOR's capital gains tax domicile guidance.

Homestead

Washington's homestead exemption is automatic, no filing required, and protects the greater of $125,000 or the county median sale price of a single-family home from most creditors under RCW 6.13. In practice the county median controls almost everywhere, since it routinely exceeds $125,000 (King County's median alone was around $968,300 in the most recent published data).

New Resident Tax Traps

New residents moving to Washington face no general wage income tax, but anyone with significant unrealized long-term capital gains needs to understand that Washington's capital gains excise tax applies based on domicile at the time of a sale, meaning a large stock sale executed after establishing Washington domicile is Washington-taxable even if the gain accrued almost entirely while living elsewhere. High earners should also plan for the 2028 Millionaires' Tax on income over $1 million, which begins applying to Washington residents and Washington-source income for nonresidents starting tax year 2028.

What Changes on Tax

Ohio Top Rate

2.75% (state, tax year 2026); municipal income taxes up to roughly 3% stack on top in most cities

Washington Top Rate

9.9% (phasing in 2028; no general wage income tax before then)

Moving from Ohio to Washington raises the top marginal income tax rate from about 3% to about 9.9%, an increase of roughly 6.9 percentage points.

Withholding Reciprocity

Ohio and Washington 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

Ohio uses common law marital property rules and Washington is a community property state. Property acquired during marriage after the move may be characterized differently going forward, which matters for estate planning and for basis step-up on a spouse's death.

Beyond Income Tax

Ohio

Capital gains: Ohio has no separate capital gains rate. Gains are included in federal adjusted gross income, which flows to the Ohio return and is taxed at the same rate as other income.

Estate or inheritance tax: None. Ohio repealed its estate tax for deaths occurring on or after January 1, 2013, and has no inheritance tax. Only the federal estate tax, with its far higher exemption, can apply to an Ohio decedent's estate.

Property tax: Average effective property tax rate runs roughly 1.4%, among the higher rates in the Midwest, and varies significantly by county and school district. The homestead exemption reduces taxable value for qualifying senior and disabled homeowners but is not a general portability benefit like Florida's.

Sales tax: State rate is 5.75%; combined with average local county and transit rates, the statewide average is about 7.2%, though rates vary by county since Ohio permits local sales tax add-ons.

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%.

Who This Move Applies To

Travel Nurses

In Ohio

Ohio has no separate statutory carve-out for travel nurses; a nurse on assignment is measured under the same contact-period and bright-line rules as anyone else. The recurring problem practitioners flag nationally, and one that shows up in Ohio specifically, is a nurse who claims a Florida or Texas tax home on paper but actually lives in an Ohio rental apartment for most of the year and rarely if ever visits the claimed home state; that pattern has drawn audits that disallow the out-of-state tax home entirely, which exposes the tax-free travel stipends to tax and typically requires filing an Ohio resident return plus nonresident returns in every other state worked.

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.

Professional Athletes

In Ohio

Ohio cities apply municipal jock taxes to visiting professional athletes, but the method changed after the Ohio Supreme Court's 2015 Hillenmeyer decision. Cleveland had taxed visiting players using a games-played method, which the court struck down as a due process violation; municipalities must now use a duty-days method that allocates income based on the ratio of days worked in the city (games, practices, mandatory team activities) to total duty days for the season. This affects visiting teams playing the Browns, Bengals, Guardians, Reds, Cavaliers, and Blue Jackets, and it also applies to those home franchises' own players when Ohio is their tax home.

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.

Snowbirds, Long Visitors, and RVers

In Ohio

The Ohio-specific snowbird scenario is a retiree or seasonal resident who keeps an Ohio home while wintering in Florida or another warm-weather state. If that person keeps their contact periods under 213 for the full year, maintains a genuine abode outside Ohio, gives up the Ohio driver's license, does not claim the Ohio homestead exemption, and files Form IT NRS by October 15, they qualify for the irrebuttable nonresident presumption regardless of how nice the Ohio house is. Miss any one of those five conditions and the state falls back to the narrower facts-and-circumstances domicile factors under the 2026 version of OAC 5703-7-16.

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.

Remote Workers

In Ohio

Ohio has no state-level convenience-of-the-employer rule. The practical issue for remote workers is municipal: under the 20-day occasional entrant rule, an employer withholds to the employee's principal place of work until the employee exceeds 20 days working in a different Ohio municipality, at which point withholding must shift to that city. Ohio law also recognizes a 'qualifying remote work location,' which can be an employee's home, for sourcing municipal tax when the employee works primarily from home rather than a traditional office.

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.

Military

In Ohio

Ohio follows the federal Servicemembers Civil Relief Act: a servicemember whose home of record is Ohio remains an Ohio domiciliary and taxpayer regardless of where military orders station them, and a nonresident servicemember stationed in Ohio on orders is not taxed by Ohio on military pay solely because of the duty station. Since the 2023 tax year, the Military Spouses Residency Relief Act as amended lets a military spouse elect to use the servicemember's state of legal residence for state tax purposes, giving military couples more flexibility than a strict duty-station rule would allow.

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.

Airline Crew

In Ohio

Federal law (49 U.S.C. §40116) limits any state to taxing an air carrier employee's compensation only in the employee's state of residence and any state where more than 50% of pay is earned. This protects flight crew based out of Ohio hubs such as Cincinnati/Northern Kentucky (CVG) or Columbus who are domiciled in another state from having their full income pulled into Ohio taxation solely because Ohio is their duty station.

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.

Ohio to Washington FAQ

What is a 'contact period' in Ohio, and how is it different from just counting days?+

A contact period is created when someone whose home is outside Ohio stays away from that home overnight and is present in Ohio for any part of two consecutive days. It is a pair-of-days concept, not a single-day count like some states use. Ohio's bright-line test asks whether you had fewer than 213 contact periods for the full year, not whether you were physically present for fewer than some number of individual days, so a careful count has to track overnight stays, not just visits.

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.

I keep a house in Ohio and a house in Florida and go back and forth. How does Ohio decide if I'm still a resident?+

If you want the strongest protection, Ohio's bright-line test gives you an irrebuttable presumption of nonresidency, but only if you meet all five conditions for the full year: fewer than 213 contact periods, an abode outside Ohio, no Ohio driver's license, no Ohio homestead exemption, no Ohio resident tuition eligibility, and a timely Form IT NRS filed by October 15. Meet all five and Ohio cannot argue domicile facts against you. Miss even one, such as still holding an Ohio license, and the state falls back to weighing domicile factors like contact periods and voter registration.

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.

What is Form IT NRS and when is it due?+

Form IT NRS, the Ohio Nonresident Statement (formerly called IT DA), is the affidavit a taxpayer files to claim the irrebuttable presumption of full-year Ohio nonresidency. It must be filed by October 15 of the year following the tax year at issue. Filing it doesn't by itself make you a nonresident; you still have to independently meet the other four bright-line conditions, but missing the deadline forfeits the safe harbor even if everything else checks out.

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 keeping the Ohio homestead exemption hurt my nonresident claim?+

Yes, directly. Claiming the Ohio homestead exemption on a property is one of the five conditions that, if triggered, defeats the bright-line irrebuttable nonresident presumption outright, regardless of your contact period count. County auditors administer the homestead rolls separately from the Department of Taxation, but the two records are cross-checked, so a homestead claim on a house you're calling a vacation home is one of the more obvious contradictions an auditor looks for.

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.

If I move out of Ohio, do I still owe Ohio tax on income from my old job or business?+

Ohio doesn't have a broad convenience-of-the-employer rule at the state level, so simply teleworking for an Ohio employer after you move doesn't automatically create Ohio tax exposure the way it can in New York. But Ohio-source income, business income sourced to Ohio activity, and compensation for work actually performed in Ohio before your move remain taxable under normal sourcing rules, and you'll need Ohio Schedule IT NRC with your part-year Form IT 1040 to allocate what's actually Ohio income.

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.

I heard Ohio cities also have their own income tax. Does moving out of the state fix that too?+

Not automatically. Ohio's state bright-line and domicile rules are separate from municipal income tax, which is administered by the city or by an agency like RITA or CCA. If you keep working in an Ohio city more than 20 days a year after you move, that city's occasional entrant rule can still pull your wages for those days into its withholding and filing requirements, independent of whether you've established state-level nonresidency.

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.
