Moving from Virginia to Idaho: Residency, Taxes, and What to Prove
Virginia scrutinizes departures closely, so this move is as much an exit-documentation project as a tax question: the top income tax rate drops from 5.75% to 5.30%.
Residency Tests Side by Side
Virginia uses a 183-day statutory residency threshold, while Idaho uses 270 days. Track both thresholds separately during a transition year rather than assuming they line up.
| Factor | Virginia | Idaho |
|---|---|---|
| Statutory Residency Test | Virginia Code §58.1-302 defines 'resident' to include any individual domiciled in Virginia during the taxable year, and separately, any individual not domiciled in Virginia who nonetheless maintains a place of abode in Virginia for more than 183 days in the aggregate during the year. This second category, called an actual resident, is taxed as a Virginia resident on worldwide income regardless of domicile, the same structural approach used by New York and several other statutory-residency states. | Idaho Code §63-3013 defines a resident as an individual either domiciled in Idaho for the entire taxable year, or someone who maintains a place of abode in Idaho for the entire taxable year and spends in the aggregate more than 270 days of the taxable year in Idaho, a materially higher threshold than the 183-day test most states use. Presence within the state for any part of a calendar day counts as a full day toward that 270-day total. |
| Domicile Test | Virginia uses a multifactor, intent-based test to determine domicile and, importantly, requires both elements together to change it: the taxpayer must abandon Virginia domicile with no intent to return, and must simultaneously establish a new domicile elsewhere through physical presence plus intent to remain. Virginia Tax's published guidance states no single factor is dispositive; a bare declaration of intent or physical relocation alone is not enough, and continuing Virginia ties like a Virginia driver's license or voter registration are treated as evidence domicile was not actually abandoned. | Idaho defines domicile administratively (IDAPA 35.01.01.030 and the Tax Commission's public guidance) as the place that is the center of an individual's personal and business life, the permanent home a person intends to return to whenever absent. An individual can have multiple residences but only one domicile at a time, and once established, domicile persists until it is affirmatively abandoned, a new one is acquired, and the person is actually living in the new domicile. Evidence weighed includes where the family lives, comparison of homes in different states, where business activity occurs, how time is actually spent during the year, where sentimentally important belongings are kept, and whether the person has given up an Idaho driver's license or the Idaho homeowner's exemption. |
| Day Count Threshold | 183 days | 270 days |
| Any Part of a Day Rule | Virginia's statute measures aggregate days maintaining a place of abode in Virginia, not single calendar-day presence, and does not publish an explicit any-part-of-a-day rule the way New York's regulations do. In practice this makes Virginia's actual-resident test closer to a cumulative day-count test than a strict any-part-of-day trigger. | Yes. Idaho Code §63-3013(1)(b) explicitly states that presence within the state for any part of a calendar day counts as a full day toward the 270-day aggregate threshold, the strict any-part-of-a-day standard. |
| Presumptions | Virginia Tax guidance treats a return to Virginia within six months of leaving as generally indicating no intent to have established residency elsewhere, similar to the boomerang concepts used by Kentucky and other nearby states, though Virginia frames this as evidence within the intent-based domicile test rather than an automatic statutory rule. | None published as a separate presumption distinct from the domicile-plus-270-day statutory test; Idaho instead runs its 445-day absence safe harbor (below) as the primary mechanism for domiciled Idahoans to be treated as nonresidents. |
| Safe Harbors | None published | 445-day absence exception |
Leaving Virginia
Virginia is named in national practitioner discussions, alongside New York, California, New Jersey, Connecticut, and Maryland, as one of the more aggressive states on residency audits, particularly for high earners whose income drops sharply the year they claim to have left. Because Virginia's domicile test requires proof of both abandonment and establishment of a new domicile, and treats retained Virginia ties like a driver's license or voter registration as evidence against a genuine move, Virginia Tax has real leverage to challenge a claimed departure even when the taxpayer has moved most of their physical presence out of state.
Trailing Income
Virginia does not have a published broad convenience-of-the-employer rule for remote workers. Virginia-source income, including wages for work actually performed in Virginia, business income sourced to Virginia activity, and gains from Virginia property, remains taxable to a nonresident after departure under standard sourcing rules reflected on Form 763.
Part-Year Filing
Part-year residents file Form 760PY, the Virginia Part-Year Resident Income Tax Return, allocating income between the resident and nonresident portions of the year. Full-year nonresidents with Virginia-source income file Form 763.
Enforcement Methods
Common Exit Mistakes
Establishing Idaho Residency
| Action | Agency | Deadline |
|---|---|---|
| Get an Idaho driver's license | Idaho Transportation Department | within 90 days of becoming an Idaho resident |
| Title and register vehicles in Idaho | Idaho Transportation Department / county assessor's motor vehicle office | within 90 days of moving to Idaho |
| Register to vote | Idaho Secretary of State / county clerk | 11 days before an election for mail or online registration; same-day registration is available at early voting locations and on Election Day with proof of residency |
Declaration of Domicile
Idaho has no formal declaration-of-domicile filing comparable to Florida's. The Tax Commission's own guidance points to concrete, checkable evidence instead: where your family lives, where you do business, how you actually spend your time during the year, where sentimentally important belongings are kept, and whether you've obtained an Idaho driver's license or filed for the Idaho Homeowner's Exemption.
Homestead
Idaho's Homeowner's Exemption (Idaho Code §63-602G) exempts 50% of a primary residence's assessed value, capped at $125,000, from property tax, but requires an affirmative application with the county assessor rather than applying automatically. It lasts only until ownership changes or the home stops being used as the owner's primary residence, so a person who moves out but forgets to cancel the exemption leaves an easy paper trail contradicting a claimed departure.
Voter Registration
Mail and online registration must be received 11 days before an election; Idaho also permits same-day registration in person at early voting locations and on Election Day with proof of residency. https://voteidaho.gov/voter-registration/
Vehicle Registration Deadline
90 days
New Resident Tax Traps
Idaho taxes worldwide income from the date Idaho domicile begins, requiring the Form 43 part-year apportionment for the year of the move. Because Idaho and Washington are both community property states, a couple where one spouse lives and works in Idaho and the other in Washington must generally report one-half of all community income, including the out-of-state spouse's earnings, on the Idaho return, a wrinkle that surprises newly arrived couples who assume only Idaho-source income is reportable.
What Changes on Tax
Virginia Top Rate
5.75%
Idaho Top Rate
5.30%
Moving from Virginia to Idaho drops the top marginal income tax rate from about 5.75% to about 5.3%, a reduction of roughly 0.45 percentage points.
Withholding Reciprocity
Virginia and Idaho 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
Virginia uses common law marital property rules and Idaho 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
Virginia
Capital gains: Virginia has no separate capital gains rate. Gains are included in federal adjusted gross income and taxed as ordinary income under the same graduated brackets, so long-term gains can face the 5.75% top rate.
Estate or inheritance tax: None. Virginia's estate tax was effectively repealed for deaths on or after July 1, 2007, when the state decoupled from the federal state death tax credit, and Virginia has never had an inheritance tax. Only the federal estate tax can apply to a Virginia decedent's estate.
Property tax: Average effective property tax rate is about 0.8%, below the national average, though Northern Virginia localities run meaningfully higher in dollar terms due to home values. Real estate tax relief for elderly and disabled homeowners is a local-option program under Va. Code §58.1-3210 that each county or city may adopt separately, with income and asset limits set locally rather than by the state.
Sales tax: State sales tax rate is 5.3% (a portion of which is a statewide local tax), with some regions, including Northern Virginia and Hampton Roads, adding regional add-ons that push the combined rate higher.
Idaho
Capital gains: Taxed as ordinary income at the flat rate, but Idaho allows a deduction of 60% of the net capital gain from the sale of qualifying Idaho property under Idaho Code §63-3022H. Qualifying property generally means Idaho real property held at least 12 months (18 months if sold before January 1, 2005), or certain business assets, cattle, and horses held for the required period; the deduction is claimed on Form CG and does not apply to gains on out-of-state property or most financial assets.
Estate or inheritance tax: None. Idaho has no estate tax and no inheritance tax.
Property tax: Effective rate is roughly 0.50% of value. Idaho's Homeowner's Exemption exempts 50% of a primary residence's assessed value up to a $125,000 cap (Idaho Code §63-602G), but unlike an automatic homestead protection this requires an affirmative application with the county assessor and lasts only until ownership changes or the home stops being the owner's primary residence, making it an easy domicile cross-check point.
Sales tax: 6.00% state rate, with a low average combined state-and-local rate of about 6.03%, since Idaho has very limited local-option sales taxes (mostly a handful of resort cities).
Who This Move Applies To
Travel Nurses
In Virginia
Virginia applies the same actual-resident and domicile tests to travel nurses as to anyone else: a nurse not domiciled in Virginia who maintains a Virginia abode for more than 183 aggregate days during assignments becomes an actual resident taxed on worldwide income. The nationally common problem, a nurse claiming a no-tax-state tax home while actually living in a Virginia rental for most of the year, is analyzed under this same statutory framework rather than a nurse-specific carve-out.
In Idaho
Boise's hospital systems and Idaho's rural-hospital travel contracts make the state a modest but real travel-nurse market. A nurse genuinely domiciled in Idaho who takes Idaho contracts is simply taxed as a resident. A nurse claiming an Idaho tax home while working elsewhere needs a real, regularly used, duplicated-expense Idaho residence; claiming Idaho as a federal away-from-home tax home while also trying to use the 445-day absence exception for Idaho state tax purposes is explicitly disqualifying under Idaho's own rule, so the two claims cannot be made consistently.
Professional Athletes
In Virginia
Virginia has historically had no NFL, NBA, MLB, or NHL franchise physically based in the Commonwealth, though the Washington Capitals and Wizards' NBA/NHL practice facility and a planned new arena project have brought professional sports infrastructure into Northern Virginia. Nonresident athletes and entertainers earning income for events performed in Virginia are subject to the state's standard nonresident sourcing rules on Form 763, but there is no widely published Virginia-specific duty-days regulation comparable to New York's.
In Idaho
Idaho has no major professional sports franchise in the four big US leagues, so jock-tax exposure runs almost entirely one direction: Idaho-domiciled or Idaho-resident athletes are taxed on income earned while playing in other states under those states' own apportionment rules, and nonresident athletes visiting Idaho for occasional events owe Idaho tax on Idaho-source duty days under the state's standard nonresident income sourcing.
Snowbirds, Long Visitors, and RVers
In Virginia
The Virginia snowbird risk runs through the aggregate 183-day actual-resident test: a retiree who keeps a Virginia home and spends more than 183 aggregate days there in a year, even while also wintering in Florida, becomes an actual Virginia resident taxed on worldwide income regardless of where they consider themselves domiciled. Because Virginia measures aggregate days maintaining the abode rather than a stricter any-part-of-day rule, careful counting of total days present, not just overnight stays, matters for anyone trying to stay under the threshold.
In Idaho
Idaho's 270-day statutory threshold is unusually generous compared to the 183-day standard most states use, but it comes paired with the strict any-part-of-a-day counting rule, so a snowbird or long-term visitor who owns or leases an Idaho home needs to track every day with any Idaho presence, not just overnight stays, against that 270-day ceiling. Idaho's own seasonal-worker example (a couple splitting time between an Alaska fishing operation and an Idaho off-season home) shows the state applies the ordinary domicile-or-270-day test to seasonal residents just as it would to anyone else, with no special seasonal carve-out.
Remote Workers
In Virginia
Virginia has no published convenience-of-the-employer rule. A nonresident who works remotely for a Virginia-based employer while physically located and domiciled outside Virginia is generally not taxed by Virginia on that income, since Virginia sources wages based on where work is actually performed rather than the employer's location.
In Idaho
Idaho has no convenience-of-employer rule: a nonresident performing all work physically outside Idaho for an Idaho-based employer is not Idaho-taxed on those wages. Idaho, particularly the Boise metro area, has drawn a steady stream of remote workers relocating from higher-cost West Coast states since 2020; because Idaho and Washington are both community property states, a remote-working couple split between the two needs to account for the community-property income-sharing rule on their Idaho return, not just source-based sourcing.
Military
In Virginia
Virginia's domiciliary-resident category expressly includes servicemembers who entered the military from Virginia and retained Virginia as their home of record; absence from Virginia on military orders does not by itself cancel Virginia domicile. Under the federal SCRA and Military Spouses Residency Relief Act as amended, a nonresident servicemember stationed in Virginia on orders is not taxed on military pay solely because of the duty station, and a military spouse can generally elect the servicemember's state of legal residence.
In Idaho
Idaho follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act, and Idaho's own guidance walks through the distinction between military home of record and state of legal residence/domicile: a service member stationed in Idaho under orders (for example, at Mountain Home Air Force Base) is taxed based on domicile, not the posting, active-duty military pay is not Idaho-taxed for nonresident service members, and a nonmilitary spouse can independently be a resident, part-year resident, or nonresident depending on their own domicile and MSRRA elections.
Airline Crew
In Virginia
Federal law (49 U.S.C. §40116) limits states to taxing an air carrier employee's compensation only in the state of residence and any state where more than 50% of pay is earned, protecting flight crew connected to Virginia operations, including those based near Washington Dulles, from having their full income pulled into Virginia taxation solely because of duty station if they are domiciled elsewhere.
In Idaho
Boise Airport is not a major airline crew base, so Idaho's most relevant federal transportation carve-out runs to interstate rail and motor carrier employees rather than airline crew specifically: Idaho's guidance confirms that employees of interstate rail or motor carriers with regularly assigned duties in more than one state are, under federal law, taxable only in their state of residence, with the Idaho-earned portion of a nonresident's income remaining Idaho-taxable.
Tools for This Move
Virginia to Idaho FAQ
How many days can I spend in Virginia before I become a resident, even if I'm domiciled somewhere else?+
Under Virginia Code §58.1-302, if you're not domiciled in Virginia but maintain a place of abode there for more than 183 aggregate days during the year, you become an actual resident taxed on worldwide income regardless of domicile. Virginia counts aggregate days maintaining the abode, not a stricter any-part-of-day rule, so total days present across the year is what matters, not just individual short visits.
Does Idaho use the 183-day rule?+
No. Idaho's statutory residency threshold is 270 days, not 183, and any part of a calendar day with Idaho presence counts as a full day toward that total under Idaho Code §63-3013(1)(b). You're a statutory resident if you maintain a place of abode in Idaho for the entire year and hit that 270-day aggregate, independent of domicile.
I moved out of Virginia but kept my driver's license. Does that matter?+
Yes, significantly. Virginia's domicile test requires proof you abandoned Virginia domicile with no intent to return and established a new one elsewhere with genuine intent to remain. Virginia Tax's published guidance treats continuing Virginia ties like a Virginia driver's license or voter registration as evidence you have not actually abandoned Virginia domicile, even if you're now physically living somewhere else most of the time.
I'm domiciled in Idaho but working out of state for years. Am I still an Idaho resident?+
Not necessarily, if you qualify for Idaho's 445-day absence exception: being out of Idaho for at least 445 days within a 15-month period lets a domiciled Idahoan be treated as a nonresident. But the exception doesn't apply if your spouse or minor children keep living in your Idaho home more than 60 days a year, or if you claim Idaho as your federal tax home for away-from-home expenses.
I keep two homes and go back and forth between Virginia and a no-tax state. How does Virginia decide if I'm a resident?+
Two separate tests can catch you. First, if you're not domiciled in Virginia but maintain a Virginia abode for more than 183 aggregate days in the year, you're an actual resident regardless of domicile. Second, if you are domiciled in Virginia, you remain a domiciliary resident on worldwide income unless you can prove you both abandoned Virginia domicile with no intent to return and established genuine domicile elsewhere, which retained Virginia ties like a driver's license or voter registration can undercut.
How many months can I spend in Idaho as a snowbird before I owe Idaho income tax?+
Up to 270 days in the aggregate during the year, since Idaho's statutory residency test kicks in above that threshold for anyone maintaining an Idaho place of abode. But Idaho counts any part of a day as a full day, so short visits add up faster than in states with a majority-of-day rule.
I moved away from Virginia but had to move back within a few months. Does that hurt my case?+
It can. Virginia Tax's guidance treats a return to the state within about six months of leaving as generally indicating you never actually intended to establish residency elsewhere, which works against a claimed domicile change for the period in between. This mirrors similar boomerang-style rules used by neighboring states like Kentucky, though Virginia frames it as evidence in the intent-based test rather than an automatic statutory trigger.
What form do I file if I only lived in Idaho part of the year?+
Form 43, the Idaho Part-Year Resident & Nonresident Income Tax Return. If you and your spouse have different residency statuses and file a joint federal return, you must also file a joint Idaho Form 43, with each spouse's status listed separately.
What does it cost to defend a Virginia residency audit?+
No published statewide figure exists. Virginia is consistently grouped by practitioners alongside New York, California, New Jersey, Connecticut, and Maryland as one of the more aggressive residency-audit states, particularly for high earners whose income drops sharply the year they claim to have left, which implies defense costs for a contested Virginia case can run comparably high, but no firm has published a specific dollar range.
Does Idaho tax Social Security?+
No. Idaho fully exempts Social Security benefits from state income tax. Other retirement income like pensions, 401(k), and IRA withdrawals is generally taxed at the flat 5.30% rate, though a separate Retirement Benefits Deduction covers qualifying public-system pensions for taxpayers 65 and older or 62 and disabled.
Do I have to file a Virginia return for the year I move out?+
Yes. Use Form 760PY, the Virginia Part-Year Resident Income Tax Return, which allocates your income between the period you were a Virginia resident and the period you were not. If you have Virginia-source income after becoming a full-year nonresident in a later year, that's reported on Form 763 instead.
Does Idaho have a capital gains tax break?+
Idaho taxes capital gains as ordinary income but allows a 60% deduction on net gains from qualifying Idaho property, generally real property held at least 12 months, claimed on Form CG. The deduction is specific to Idaho property; gains on out-of-state real estate or most stocks and financial assets don't qualify.
