State Residency Guide
Washington, DC Residency
DC runs a graduated income tax with six brackets: 4% up to $10,000, 6% from $10,001 to $40,000, 6.5% from $40,001 to $60,000, 8.5% from $60,001 to $350,000, 9.25% from $350,001 to $1,000,000, and 10.75% above $1,000,000. The top rate, raised as part of a District budget push to fund paid leave and other priorities, is the third highest in the country behind only California and Hawaii.

Residency Tests
Statutory Residency Test
Under D.C. Code § 47-1801.04(42), an individual is a DC resident if domiciled in DC at any time during the tax year, or if the individual maintained a place of abode in DC for an aggregate of 183 days or more during the tax year, regardless of domicile. The statutory prong does not require actual physical presence in DC for those days; it only requires that the taxpayer maintained ongoing, unfettered access to a DC dwelling for 183 or more days. That is a materially different test from the abode-plus-183-days-physically-present standard used by New York and most other statutory residency states, and it was the central fact in the Michael Saylor False Claims Act case described below.
Domicile Test
DC follows the common law two-part domicile test applied in Bartholomew v. District of Columbia Office of Tax and Revenue: physical presence in the new location, plus a genuine intent to abandon the former domicile and remain in the new one for an indefinite period. Once OTR has assessed, the burden is on the taxpayer to prove both elements. OTR and the Office of Administrative Hearings weigh the full pattern of a person's life, including where they own or lease housing, where a spouse and family live, voter and vehicle registration, and where the person actually spends time, with no single factor controlling. A temporary or transitory absence from DC does not, by itself, change domicile.
Day Count Threshold
183 days
Any Part of a Day Rule
DC's statutory test is not a physical-presence day count, so the usual 'any part of a day counts' question does not apply the way it does in New York or California. What DC counts is days of maintained access to a DC abode, meaning an owned or leased DC residence the taxpayer could return to and use, whether or not they were actually in the District that day. A genuine lease-out that cuts off the taxpayer's own access is what breaks the count; simply being physically absent from DC while still holding a key does not.
Presumptions
None published beyond the two statutory tests themselves. DC has no separate day-count presumption comparable to California's nine-month presumption or New Mexico's 185-day rule.
Safe Harbors
Congressional staff and elected-official exemption
D.C. Code § 47-1801.04(42) excludes certain federal officeholders and their personal staff from DC resident status even while living in DC during sessions: elected officers of the United States, U.S. Supreme Court Justices, presidential appointees confirmed by the Senate, and personal or committee staff of a member of Congress who are bona fide residents of the same state as that member. The exemption holds only while the person maintains that home-state domicile, and it does not extend to staff who live in DC but are not from the same state as the member they work for, or to executive-branch political appointees generally.
D.C. Code § 47-1801.04(42)
Leaving Washington, DC
DC's exit risk runs almost entirely through the statutory abode test and OTR's non-filer matching, not through a New York- or California-style multi-year audit apparatus. OTR routinely compares federal returns that list a DC address against its own D-40 filings, and a gap generates a non-filer inquiry. The more severe exposure is DC's amended False Claims Act, which lets private whistleblowers, often ex-employees, neighbors, or business associates, sue on the District's behalf and share in treble damages when a claimed exit looks like fraud rather than an honest dispute. The Saylor case is the proof of concept: DC's Attorney General intervened in a qui tam suit alleging MicroStrategy co-founder Michael Saylor lived in a Georgetown penthouse overlooking the Potomac, where he kept his yachts, while filing as a Virginia and then Florida resident from 2005 through 2021 to avoid more than $25 million in DC income tax. He and MicroStrategy settled in June 2024 for $40 million without admitting wrongdoing, the largest income tax recovery in DC history.
Trailing Income
Because the federal Home Rule Act bars DC from taxing any portion of a nonresident's personal income, DC has essentially no trailing-income regime once a person's domicile has genuinely changed and their DC abode-days have dropped below 183. There is no DC convenience-of-the-employer rule, no DC-source withholding on a former resident's wages, and no ongoing DC claim on stock options or deferred compensation earned while a DC resident the way New York or California retain sourcing claims after departure. The entire fight is therefore about whether the exit itself was real, not about what DC can still tax afterward.
Part-Year Filing
Form D-40 handles both full-year and part-year DC returns; there is no separate part-year form. A person who established or abandoned DC domicile mid-year completes the Part-Year Resident section of D-40, allocates income and deductions to the DC-resident portion of the year, and prorates the standard deduction and personal exemption by dividing days of DC residency by 365 (366 in a leap year).
Enforcement Methods
Common Exit Mistakes
Establishing Washington, DC Residency
| Action | Agency | Deadline |
|---|---|---|
| Get a DC driver license or ID | DC DMV | within 60 days of establishing DC residency if you drive in public |
| Register any vehicle kept in DC | DC DMV | within 60 days of establishing residency |
| Pass a DC DMV vehicle inspection | DC DMV | within 90 days of registration for most vehicles |
| Register to vote | DC Board of Elections | received at least 21 days before an election for advance processing; same-day registration available during early voting and on Election Day with proof of address |
| File the Homestead Deduction if you own and occupy your DC home | Office of Tax and Revenue | file by March 31 for the full current tax year; filed April 1 to September 30 gets half the current year and the full benefit going forward |
Declaration of Domicile
DC has no Florida-style formal declaration-of-domicile filing. Domicile is established through conduct and is later tested against the two-part physical-presence-plus-intent standard from Bartholomew: signing a DC lease or deed, getting a DC driver license and registering a vehicle there, registering to vote in DC, and the actual pattern of where you live and keep your life.
Homestead
The Homestead Deduction shields $91,950 of a DC home's assessed value from property tax in 2026, available only on an owner-occupied principal residence with no more than five dwelling units. It cuts both ways as evidence: applying for it supports a claim that you consider the DC property your primary home and domicile, while OTR runs an automated cross-match of homestead applicants against other jurisdictions' records specifically to catch people who keep the DC homestead while also filing as a resident, or claiming an equivalent break, somewhere else.
Voter Registration
Register online, by mail, or in person through the DC Board of Elections. Applications must be received at least 21 days before an election to be processed in advance, though DC also allows same-day registration during early voting and on Election Day with proof of a current DC address. https://www.dcboe.org/voters/register-to-vote

New Resident Tax Traps
A new DC domiciliary is taxed on worldwide income from the date DC residency begins, reported on Form D-40 with the Part-Year Resident section completed for the year of the move. DC has no local sales tax variation to create a use-tax surprise, but a new resident titling a vehicle in DC owes DC excise tax on the transaction, and anyone buying a first DC home should file the Homestead Deduction promptly since a late application forfeits half a year of the benefit.
Tax Profile
Capital Gains
DC has no separate capital gains rate. Gains are taxed as ordinary income at the same graduated brackets, so a District resident in the top bracket can pay 10.75% on a capital gain, with none of the preferential long-term treatment federal law provides.
Retirement Income
Social Security benefits are fully exempt from DC income tax. A resident who does not use the Social Security exclusion may instead deduct up to $3,000 of pension, annuity, or other qualifying retirement income, but a taxpayer cannot claim both the Social Security exclusion and the $3,000 deduction on the same return. Beyond that deduction, private pensions, 401(k), and IRA withdrawals are taxed as ordinary income under DC's brackets.
Estate or Inheritance Tax
DC has an estate tax but no separate inheritance tax. The 2026 exemption is $4,988,400 per estate, roughly a third of the federal exemption, so a District estate can owe DC estate tax even when it owes nothing federally. Taxable estates above the exemption are taxed at graduated rates from 11.2% up to 16%.
Property Tax
The nominal Class 1 residential rate is $0.85 per $100 of assessed value. After the Homestead Deduction, which shields $91,950 of assessed value from tax in 2026, and other credits, the Tax Foundation puts DC's effective rate on owner-occupied housing at about 0.60%, low by national standards even as assessed values in the District have climbed quickly.
Sales Tax
The general sales tax rate is 6% through September 30, 2026, rising to 7% on October 1, 2026 under the District's FY2026 budget. DC has no counties or independent municipalities layering on additional local tax, so the citywide rate is the only rate; prepared restaurant food and takeout carry a separate 10% rate.
Community Property
Washington, DC uses common law, equitable-distribution marital property rules.
Wage-withholding reciprocity: Maryland, Virginia.
Special Situations
Travel Nurses
DC's federal prohibition on taxing nonresident income is unusually good news for travel nurses. A nurse whose tax home is genuinely elsewhere and who works a contract at a DC hospital, such as Georgetown, MedStar Washington Hospital Center, Children's National, or GW Hospital, owes no DC income tax on that assignment's wages or stipends, so long as they are not domiciled in DC and have not maintained a DC abode for 183 or more days; there is no DC-source nonresident withholding the way there would be almost anywhere else with an income tax. The exposure runs the other way: a nurse who takes back-to-back DC-area contracts in the same leased apartment can cross the 183-day abode-maintenance threshold and become a DC statutory resident taxed on all worldwide income, independent of what their agency's paperwork lists as their tax home.
Professional Athletes
DC is one of the only income-tax jurisdictions in the country with no jock tax at all: Congress has repeatedly blocked DC Council attempts to tax nonresident athletes' duty-day income under the same Home Rule Act provision that bars any DC tax on nonresidents generally. Visiting players who take the court or ice at Capital One Arena (Wizards, Capitals) or the field at Nationals Park (Nationals) owe zero DC income tax on those games, unlike visiting players in every state that hosts an NBA, NHL, MLB, or NFL team. The Commanders currently play home games at Northwest Stadium in Landover, Maryland, so visiting teams' duty days there generate Maryland exposure rather than DC exposure; that changes once the team's planned stadium at the RFK campus in DC opens, expected around 2030, though DC's no-jock-tax rule means it still won't create DC tax on visiting players even then. DC-domiciled players on the Wizards, Capitals, Nationals, Mystics, or Commanders remain fully taxable by DC as residents on all of their income, including duty days played in states that do tax them as visitors.
Remote Workers
Because DC cannot tax nonresidents at all, it has no convenience-of-the-employer rule and no equivalent risk for someone who moves out of DC and keeps working remotely for a DC-based employer; once residency has genuinely ended, that income is simply outside DC's reach. The live issue for remote workers is the same statutory residency question everyone else faces: keeping a DC apartment as a part-time base while working remotely from elsewhere can, on its own, add up to 183 days of maintained abode access and trigger DC statutory residency regardless of where the paycheck is sourced.
Military
DC follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose legal residence is outside DC does not become a DC domiciliary or statutory resident solely because military orders station them in the District, and military pay is not DC-source income. A nonresident military spouse living in DC under MSRRA can file Form D-4 with their employer to stop DC withholding, and either spouse can use Form D-40B to recover DC tax withheld in error.
Students
DC hosts a large transient student population at Georgetown, GW, American, Howard, and Catholic University, and OTR treats a student's domicile as following their parents' or prior home-state domicile by default. A student who comes to DC solely to attend school and intends to return home after graduation does not become a DC domiciliary just by living in a DC dorm or apartment during the school year. A student who takes affirmative steps, such as accepting full-time DC employment after graduation or obtaining a DC driver license with intent to stay, can establish DC domicile; a student who occupies a DC apartment for 183 or more days in a calendar year can separately become a statutory resident regardless of intent.
Snowbirds and Long Visitors
The DC-specific snowbird risk differs from other high-tax jurisdictions: because the statutory test counts days a DC home is maintained rather than days physically present, a person who keeps a DC pied-a-terre available year-round while wintering elsewhere can cross 183 days of abode-maintenance even if they were only physically in DC a fraction of that time. Genuinely renting the DC unit out, with no reserved access for the taxpayer, is the fact pattern that breaks the abode-maintenance count; simply leaving it empty or available for personal use most of the year does not.
Airline Crew
DC itself has no commercial airport within its borders; Reagan National and Dulles are in Virginia and BWI is in Maryland, so DC does not have an airline crew base the way a hub city like Atlanta or Charlotte does. The federal wage-source rule for air carrier employees (49 U.S.C. § 40116) is largely moot for DC specifically, since DC's own bar on taxing nonresident income already goes further than that carve-out for any nonresident flight crew who might occasionally overnight in the District.
Retirees
DC's full exemption of Social Security and its $3,000 retirement-income deduction help, but its 10.75% top income tax rate, an estate tax that starts under $5 million, well below the federal exemption, and high housing costs are the reasons most retirees who can afford to leave DC choose Maryland, Virginia, or a no-tax state instead. Retirees who stay benefit from the Homestead Deduction and, if 65 or older with household income under $163,500 in 2026, a 50% property tax reduction and a 2% annual cap on assessed-value growth under D.C. Code § 47-863.
Audit Profile
Statute of Limitations
Generally three years from the date a return is filed, extended to six years if more than 25% of gross income is omitted, and unlimited if no return was ever filed or the return was false or fraudulent, per D.C. Code § 47-4301. Because there is no time limit on a year that was never filed, OTR and the DC Attorney General's Office have pursued cases stretching back well over a decade, as in the Saylor matter, which covered tax years 2005 through 2021.
Typical Lookback
OTR does not publish a standard audit-lookback figure the way practitioner communities describe for New York or California. In practice, a straightforward residency audit follows the three-year assessment window on filed returns, while the more consequential DC-specific risk runs through the False Claims Act channel, which has no comparable time limit once the underlying conduct is treated as fraudulent nonfiling.
Defense Cost Range
No published DC-specific figures exist for the cost of defending a routine residency audit. The Saylor case shows the outer bound of what's at stake when the District treats an exit as fraudulent rather than merely wrong, a $40 million settlement after years of litigation, but that scale reflects a False Claims Act fraud claim, not a typical audit, and most DC residency disputes never reach that level of exposure or public disclosure.
Known Cases
Bartholomew v. District of Columbia Office of Tax and Revenue
The DC Court of Appeals affirmed a DC domicile assessment against a taxpayer who worked in the U.S. Virgin Islands for about three years while his wife and daughter stayed in the family's DC home. Even though he likely would have qualified as a bona fide USVI resident on the facts, the court applied the two-part domicile test, physical presence in the new location plus genuine intent to remain indefinitely, and held he failed to prove intent, in part because he never filed a USVI tax return.
No. 12-AA-169 (D.C. Ct. App. Oct. 24, 2013)
District of Columbia ex rel. whistleblower v. Saylor and MicroStrategy, Inc.
DC's Attorney General, intervening in a False Claims Act qui tam suit, alleged that MicroStrategy co-founder Michael Saylor lived in a Georgetown penthouse from 2005 to 2021 while claiming Virginia and then Florida residency, avoiding more than $25 million in DC income tax. Saylor and MicroStrategy settled in June 2024 for $40 million without admitting wrongdoing, the largest income tax recovery in DC history and the first major test of DC's amended False Claims Act as a residency-enforcement tool.

Washington, DC Residency FAQ
I live in Maryland or Virginia but work in DC. Do I owe DC income tax on my paycheck?+
No. Federal law, specifically the Home Rule Act of 1973, bars DC from taxing any part of a nonresident's income, even wages earned by commuting into the District every day. File Form D-4A, Certificate of Nonresidence in DC, with your employer so they stop withholding DC tax; Maryland and Virginia residents working in DC pay tax only to their home state instead.
I keep an apartment in DC that I only visit a few times a year, but I say I live in Florida. Could I still owe DC tax?+
Yes, and this is DC's biggest trap. Unlike most states, DC's statutory residency test does not count days you were physically present, it counts days you maintained access to a DC home. Under D.C. Code § 47-1801.04(42), keeping a DC place of abode available to you for 183 days or more in a year can make you a DC statutory resident taxed on worldwide income even if you were rarely actually in the District, unless the apartment is genuinely rented out with no reserved access for you.
How did DC catch Michael Saylor if he said he lived in Florida?+
A whistleblower sued under DC's False Claims Act, and the DC Attorney General's Office intervened with a complaint alleging Saylor's actual home was a penthouse overlooking the Georgetown waterfront, where he kept his yachts, while he filed as a Virginia and then Florida resident from 2005 to 2021. He and MicroStrategy settled in June 2024 for $40 million, the largest DC income tax recovery ever, without admitting wrongdoing. It shows DC will use ordinary lifestyle evidence, not just tax filings, to prove a claimed domicile change never actually happened.
Do Hill staffers who work for their home-state member of Congress have to pay DC income tax?+
Not if they qualify for DC's specific carve-out. D.C. Code § 47-1801.04(42) exempts personal or committee staff of a member of Congress from DC resident status, even while living in DC during sessions, as long as the staffer is a bona fide resident of the same state as the member they work for. Staff who work for a member from a different state than where they actually live, or who take a job with a different employer, do not get this exemption and are taxed the same as anyone else living in DC.
If I'm a travel nurse on a DC hospital contract, do I owe DC income tax even though my tax home is somewhere else?+
Generally no. Because DC cannot tax nonresident income at all, a travel nurse who is domiciled elsewhere and has not maintained a DC place of abode for 183 days or more in the year owes nothing to DC on that assignment's wages or stipends, unlike almost every state with an income tax. The risk is stacking multiple DC-area contracts in the same leased apartment long enough to cross 183 days of abode-maintenance, which can make you a DC statutory resident regardless of what your agency's paperwork says your tax home is.
Do visiting NBA, NHL, or MLB players pay DC income tax when they play a game at Capital One Arena or Nationals Park?+
No. DC is one of the only income-tax jurisdictions in the country with no jock tax on visiting athletes, because Congress has repeatedly blocked DC Council attempts to tax nonresident duty-day income under the same Home Rule Act provision that bars any DC tax on nonresidents generally. A visiting player who suits up against the Wizards, Capitals, or Nationals owes zero DC tax on that game check, something that would never happen in New York, California, or almost any other state with a major league team.
I'm active duty and stationed at a DC-area base, but my home of record is another state. Do I owe DC income tax?+
No, under the federal Servicemembers Civil Relief Act. Being stationed in DC on military orders does not make you a DC domiciliary or statutory resident, and your military pay is not DC-source income. A nonresident military spouse living with you in DC can use the Military Spouses Residency Relief Act the same way, filing Form D-4 with their DC employer to stop withholding, or Form D-40B afterward to recover DC tax withheld in error.
What's the deadline to switch my driver's license and register my car after moving to DC?+
You must get a DC driver license or ID and register any vehicle within 60 days of establishing DC residency, and most vehicles need a DC DMV inspection within 90 days of registration. DC DMV handles first-time vehicle registration in person only; you'll need your title, DC insurance, and a completed Certificate of Title/Temporary Tag Application.
Can DC tax me on income from my remote job for a DC-based employer after I move to Virginia?+
No. Because DC is barred from taxing nonresident income entirely, it has nothing like New York's convenience-of-the-employer rule; once your DC residency has genuinely ended, income from a DC employer earned while you're physically working from Virginia is simply outside DC's reach. This only protects you once you've actually stopped being a DC resident under both the domicile and 183-day abode tests, not the day you change your mailing address.
Will keeping the Homestead Deduction on my DC condo hurt me if I claim Florida residency?+
Yes, and OTR specifically cross-matches homestead applicants against records in other jurisdictions to catch exactly this. The Homestead Deduction requires the property to be your owner-occupied principal residence, so continuing to receive it while filing as a nonresident elsewhere is a direct, checkable contradiction. If you've genuinely moved, notify OTR to remove the deduction; keeping it is one of the more mechanical ways people accidentally document that they never left.
How many days can I keep my DC pied-a-terre before I become a statutory resident, even if I'm barely there?+
183 days of maintained access in a calendar year, but DC counts differently than you'd expect: it is not about how many days you were physically in the District, it's about how many days you had an available DC home to return to. A unit sitting empty but reserved for you counts the same as one you're actually using. Genuinely renting it out on a lease that cuts off your own access is what breaks the count; simply traveling elsewhere while keeping the keys does not.
What happens if I put a DC address on my federal tax return but never filed a DC resident return?+
That mismatch is one of OTR's most direct enforcement triggers. OTR routinely compares federal returns showing a DC address against its own D-40 filings, and a gap generates a non-filer inquiry. Because there is no statute of limitations on a year you never filed for, this can reach back many years, and if OTR concludes the omission was willful, DC's amended False Claims Act allows the case to be pursued as fraud, with treble damages and no comparable time bar.
