Moving from Pennsylvania to Connecticut: 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 Connecticut

The same statutory residency test applies to a travel nurse on a Connecticut hospital assignment as to anyone else: keeping a genuinely permanent Connecticut abode while accumulating more than 183 days in the state triggers statutory residency and worldwide-income taxation. Connecticut's regulatory carve-out for a non-permanent, work-related apartment gives traveling healthcare workers on shorter rotations a somewhat clearer defense than in states without that language, provided the housing is documented as temporary.

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 Connecticut

Connecticut has no major men's professional sports franchise based in the state, but it does tax nonresident athletes and entertainers on Connecticut-source income using duty-day apportionment. This reaches visiting performers and athletes at venues like Mohegan Sun and Foxwoods, and the home roster of the WNBA's Connecticut Sun, which plays at Mohegan Sun Arena.

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 Connecticut

Daniels v. Commissioner of Revenue Services is the clearest illustration of Connecticut's posture toward long-time snowbirds: a decedent who divided his time among Connecticut, Arizona, and Florida had his estate audited after death, and even though a Superior Court found his Connecticut and Florida ties 'generally equal,' the taxpayer's estate still lost under the higher clear-and-convincing evidence standard then in use. The Connecticut Supreme Court's June 2026 ruling lowered that standard to a preponderance of the evidence and sent the case back for retrial, which helps future snowbird estates but confirms Connecticut will litigate close domicile calls rather than concede them.

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 Connecticut

Connecticut enacted its own reciprocal convenience of the employer rule in 2019: a nonresident who works remotely for a Connecticut employer is taxed as if working in Connecticut if their home state, principally New York, imposes its own convenience rule on Connecticut residents. The most visible current dispute runs the other direction, a Connecticut resident, Cardozo Law School professor Edward Zelinsky, has spent years challenging New York's convenience rule for taxing the income he earns teleworking from his Connecticut home for a New York City law school; the New York Tax Appeals Tribunal upheld the rule against him again in May 2025, with further appeal pending.

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 Connecticut

Connecticut follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember or accompanying spouse domiciled elsewhere who is in Connecticut solely on military orders is not treated as a Connecticut domiciliary, and military pay is not taxed by Connecticut for a nonresident servicemember stationed there.

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 Connecticut

Federal law (49 U.S.C. §40116) limits states to taxing air carrier employee compensation only in the employee's state of residence and any state where more than 50% of pay is earned. This is relevant to crew connected to Bradley International Airport, a smaller hub than New York's or New Jersey's, who are domiciled outside Connecticut.
