Basis

DC Code §47-1801.04

The District of Columbia treats you as a statutory resident for income tax if you maintain a place of abode in DC for an aggregate of more than 183 days in the taxable year — even if your permanent home (domicile) is somewhere else. Both parts must line up in the same year: keep your days with an abode in the District at 183 or fewer and the statutory-resident rule does not bite. Note that domicile is a separate, independent route to residency that ignores the day count entirely.

Who it applies to

This matters most if you are:

• Someone who keeps an apartment or second home in DC while claiming a permanent home in another state.
• A commuter, contractor, or remote worker spending long stretches in the District without intending to make it your permanent base.
• A part-year mover whose stay in DC straddles a job or relocation and pushes the day count past the threshold.

It applies to individuals regardless of citizenship or visa status — the test turns on presence and available housing, not on where you are from. Elected officials, certain federal appointees, and their staff have specific carve-outs written into the statute.

The rule — and why it exists

DC defines residency through two independent routes in the definition of "resident":

• Statutory residency (the 183-day test). If you maintain a place of abode in the District for more than 183 days in the taxable year, you are taxed as a resident — regardless of where your domicile is.
• Domicile. If DC is your true, fixed, permanent home, you are a resident no matter how few days you spend there. This route ignores the day count entirely.

Why it exists: the District uses time spent plus a place to live as proxies for where your economic life actually sits. Pairing a day count with a place-of-abode requirement stops people who live in DC in practice from escaping residency simply by declaring a domicile elsewhere on paper.

Counting the days

1. 1Count each day you maintain a place of abode in the District during the taxable year (1 January to 31 December).
2. 2The count resets to zero at the start of each new calendar year — it is a fresh annual tally, not a rolling window.
3. 3Days are aggregated across the year, so multiple separate stays add together toward the 183-day total.
4. 4You become a statutory resident once the aggregate exceeds 183 days while you hold a place of abode in DC.

Because the window is the calendar year, a single long trip split across a year-end can leave you under the threshold in each individual year even though the trip itself is longer than 183 days.

Examples

Example 1 — clearly resident by days

You keep a rented DC apartment and stay there roughly 200 days across the year while your family home is in Virginia. You maintain a place of abode and exceed 183 days in the same calendar year, so you are a DC statutory resident and the District taxes your worldwide income for that year.

Example 2 — resident despite few days

You spend only about 90 days in the District, but DC is where your permanent, fixed home is — you vote, bank, and centre your life there. You are a resident under the domicile route even though you are nowhere near 183 days; the day count is irrelevant here.

Example 3 — a stay across year-end

You keep a DC abode from 1 October to 30 April — about 210 continuous days. Because the count resets at the calendar year, roughly 90 days fall in the first year and about 120 in the second, leaving you at or under 183 in each. Neither year alone triggers statutory residency, even though the trip exceeds six months.

Exceptions & edge cases

• Domicile overrides the count. If DC is your domicile, you are a resident below 183 days; statutory residency is only the route that matters for people domiciled elsewhere.
• No abode, no statutory test. Without a place of abode you maintain in the District, the 183-day statutory-resident rule simply does not apply — though domicile could still reach you.
• Official carve-outs. Elected officials, certain presidential appointees, and their staff have specific exclusions in the statute, aimed at people posted to DC for government service.
• Part-year situations. Moving into or out of the District mid-year can create a part-year residency period rather than full-year statutory residency; the facts of when the abode began and ended matter.

Common misconceptions

• "183 days or fewer means I'm safe." Only from the statutory test — domicile can make you a DC resident with far fewer days.
• "Only my DC income is taxed." A statutory resident is taxed on worldwide income for that year, the same as a domiciliary — not just District-source income.
• "I have to own a home for it to count." A rented apartment or any dwelling you maintain and can live in qualifies as a place of abode.
• "It's a rolling 12-month window." The count is a fresh calendar-year tally that resets every 1 January.
