Washington DC occupies a unique position in US tax law: it is not a state, but it taxes residents much like one, with a 7-bracket progressive income tax reaching 10.75% on income over $1 million. Unlike most states, DC's tax rates are relatively high across a broad middle band — the 8.5% bracket applies to nearly all income between $60,000 and $250,000, capturing the bulk of federal employees, contractors, and lobbyists who make up the district's workforce.
Because DC directly borders both Virginia and Maryland, tax arbitrage is unusually easy: a resident can move a few miles across the Potomac or the district line, keep the exact same job, and pay meaningfully less in state income tax. This guide covers DC residency rules, the district's income tax and estate tax, DC property tax and the Homestead Deduction, and what departure from DC looks like in practice.
DC residency works differently from state residency because DC is a federal district administered under the DC Code rather than a state constitution. DC has no counties and no separate municipal layer — the district government functions as both state-level and city-level government simultaneously, which is part of why DC's tax rates run higher than neighboring states for a given service level.
You are a DC resident for income tax purposes if DC is your domicile (permanent home), or if you maintain a place of abode in DC and spend 183 days or more in the district during the tax year — a statutory residency test similar to New York's. This means simply working in DC while living in Virginia or Maryland does not make you a DC resident: DC taxes based on residency, not workplace. A Virginia or Maryland resident who commutes into DC for work pays income tax only to their home state, not to DC.
To change domicile away from DC: (1) establish a genuine new primary home in the destination state; (2) obtain a new driver's licence and vehicle registration; (3) register to vote in the new jurisdiction (DC residents cannot vote for full congressional representation, so many departing residents view this step as a bonus rather than a loss); (4) update employer records, banking, and professional licences to the new address. The DC Office of Tax and Revenue (OTR) can scrutinize a claimed departure if you continue to maintain a DC residence and spend significant time there, particularly around large income or estate-planning events.
File DC Form D-40 as a part-year resident in the year you depart. DC taxes worldwide income through your departure date, and DC-source income only after departure. DC-source income includes: wages for work physically performed in DC, DC rental income, DC business income, and gains from DC real estate. Because DC's income tax does not apply to non-resident commuters at all — a rule that differs from most states, which do tax non-resident wages earned within their borders — a former DC resident who continues working in DC after moving to Virginia or Maryland owes no DC income tax on those wages, only tax to their new home state.
DC is one of relatively few US jurisdictions that does not tax non-residents on income earned within its borders. This is a direct consequence of the Home Rule Act and the district's unique federal status — Congress has historically restricted DC's ability to tax the wages of the large non-resident commuter workforce who work in DC but live in Virginia or Maryland. This makes DC departure unusually clean for wage earners: once you've genuinely established residency elsewhere, your DC tax liability on ongoing DC-based wages ends completely.
DC's tax structure combines a wide, moderately high middle-income bracket with a genuinely high top rate — a combination that drives much of the district's out-migration to nearby suburbs.
| DC Taxable Income | Rate |
|---|---|
| $0 – $10,000 | 4% |
| $10,000 – $40,000 | 6% |
| $40,000 – $60,000 | 6.5% |
| $60,000 – $250,000 | 8.5% |
| $250,000 – $500,000 | 9.25% |
| $500,000 – $1,000,000 | 9.75% |
| Over $1,000,000 | 10.75% |
The wide 8.5% bracket, covering $60,000 to $250,000, is the defining feature of DC's tax structure — it captures the large majority of DC's professional workforce, including most federal employees, contractors, and attorneys. A single filer earning $75,000 in DC pays approximately $4,960 in DC income tax, and a $100,000 earner pays approximately $6,860.
Virginia and Maryland are the two most common destination jurisdictions for departing DC residents, since both border DC directly and offer commuting distance to the same job. The comparison at $100,000 income:
| Tax | Washington DC | Virginia | Maryland |
|---|---|---|---|
| Income tax (top marginal) | 10.75% | 5.75% | 5.75% + county |
| Income tax at $100,000 | $6,860 | $4,567 | $6,366 |
| Annual savings vs DC | — | $2,293 | $494 |
Virginia offers the larger savings of the two, since Maryland's own state-plus-county 'piggyback' tax structure brings its combined burden close to DC's. A DC resident earning $100,000 who moves to Arlington or Fairfax County, Virginia saves approximately $2,293/year in income tax alone — a figure that compounds meaningfully over a career, especially since the move typically does not require changing employer.
DC imposes its own estate tax on estates above $4,988,400 (2026 exemption threshold), with progressive rates from 11.2% up to 16% on the largest estates. DC estate tax returns are filed on Form D-76. Unlike the federal estate tax, which has a much higher exemption, DC's threshold is set independently and can capture DC homeowners with substantial real estate equity, retirement accounts, and investment portfolios well before they would owe federal estate tax. Virginia has no state estate tax at all, and Maryland's estate tax exemption ($5 million) is broadly similar to DC's — meaning estate tax is a more decisive factor for departures to Virginia than to Maryland.
DC's Class 1A property tax rate for owner-occupied residential property is $0.85 per $100 of assessed value (0.85%) — moderate compared to many neighboring Virginia and Maryland counties. DC also offers a Homestead Deduction of $91,950 (2026) that reduces the taxable assessed value of an owner-occupied primary residence, saving approximately $781.58 per year for qualifying homeowners. Given DC's high median home values (often exceeding $700,000), the effective property tax bill on a typical DC home can still be substantial in dollar terms even at a relatively low percentage rate, since the rate applies to a large assessed value base.
DC fully exempts Social Security benefits from its income tax. However, most other retirement income — pension distributions, IRA withdrawals, and 401(k) distributions — is taxed at DC's regular income tax rates (4%-10.75%). This makes DC noticeably less favorable for retirees than Virginia, which offers age-based subtraction modifications for retirement income, or zero-tax states like Florida.
