Moving from Pennsylvania to Washington, DC: Residency, Taxes, and What to Prove

In Pennsylvania

Philadelphia and Pittsburgh's major hospital systems are large travel-nursing markets, and a nurse working Pennsylvania contracts needs to watch the statutory residency test: crossing 183 days of Pennsylvania presence while maintaining anything that qualifies as a permanent (not purely temporary) place of abode, an apartment lease rather than short-term corporate housing, for example, can pull the nurse into Pennsylvania statutory residency regardless of a claimed tax home elsewhere.

In Washington, DC

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.

In Pennsylvania

Philadelphia is home to the Eagles (NFL), Phillies (MLB), 76ers (NBA), and Flyers (NHL), making it one of the country's most active jock-tax markets; visiting players owe Pennsylvania nonresident tax apportioned by duty days spent in the state for games, practices, and team activities under the standard multistate duty-day framework, while Pennsylvania-based players are taxed on their full income at the flat 3.07% state rate plus any applicable Philadelphia wage tax, with credits for tax paid to other states on away-game income.

In Washington, DC

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.

In Pennsylvania

A Pennsylvania domiciliary who winters in Florida or another warm-weather state but keeps the Pennsylvania home in maintainable condition and returns for more than half the year remains a Pennsylvania resident on domicile grounds alone; the more contested scenario is the reverse, someone who has genuinely moved their domicile out of Pennsylvania but keeps a Pennsylvania house available and visits often enough to cross 183 days, which can trigger Pennsylvania statutory residency even after a real domicile change, unless the retained property qualifies as non-permanent lodging (which a fully maintained house generally does not).

In Washington, DC

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.

In Pennsylvania

Pennsylvania has no convenience-of-the-employer rule of its own; a remote worker physically performing work from Pennsylvania for an out-of-state employer generally owes Pennsylvania tax on that Pennsylvania-source income based on physical presence, and does not separately owe the employer's home state tax on those same wages unless that state applies its own convenience rule, which is the scenario Pennsylvania arrivals from convenience-rule states like New York need to watch in their employer's withholding treatment. Pennsylvania also has long-documented reciprocal wage-tax agreements with several neighboring states (commonly cited as Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia), under which a resident of one state working in the other pays tax only to their state of residence rather than both; this research pass could not obtain a fresh confirmation directly from the Department of Revenue's site this session, so verify current reciprocal-state status before relying on it for a specific filing.

In Washington, DC

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.

In Pennsylvania

Pennsylvania follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember stationed in Pennsylvania on orders does not become a Pennsylvania domiciliary solely because of the posting, and an MSRRA-eligible spouse can generally retain the servicemember's state of legal residence for tax purposes.

In Washington, DC

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.

In Pennsylvania

Philadelphia International Airport is a major American Airlines hub with a substantial resident crew population; federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence and, in narrow cases, a state where more than 50% of pay is earned, so Pennsylvania-domiciled crew are taxed on their full wages at the flat 3.07% rate regardless of how flight time is distributed across other states.

In Washington, DC

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.
