Moving from Connecticut to New Hampshire: Residency, Taxes, and What to Prove

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 New Hampshire

New Hampshire has no state income tax to complicate a travel nurse's tax-home analysis, which makes it an attractive tax-home state to claim, similar to Florida or Texas, provided the nurse genuinely maintains and returns to a New Hampshire home between assignments under the general IRS tax-home rules (Publication 463). New Hampshire itself publishes no nurse-specific guidance because it has no individual filing requirement to trigger one.

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 New Hampshire

New Hampshire has no major professional sports franchises, so it runs no state jock-tax regime of its own, and because it has no income tax, a New Hampshire-domiciled athlete owes zero state tax on the share of income attributable to New Hampshire duty days, unlike a player based in a state that both taxes and credits.

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 New Hampshire

New Hampshire places no day-count cap on long visitors of its own, since it has no statutory residency test. The exposure runs entirely the other way: someone who claims New Hampshire domicile to escape a high-tax origin state (most commonly Massachusetts) but still spends significant time and keeps a home in that origin state can be taxed there as a statutory resident regardless of the New Hampshire claim.

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 New Hampshire

New Hampshire has no convenience-of-the-employer rule (it has nothing to source, having no income tax). The real friction runs the other direction: a remote worker who moves to New Hampshire but keeps a Massachusetts-based employer needs to confirm Massachusetts is not still asserting Massachusetts-source treatment of the wages under its own COVID-era sourcing rules, which New Hampshire itself challenged (unsuccessfully, at the Supreme Court) on behalf of its residents in 2020-2021.

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 New Hampshire

New Hampshire follows the federal SCRA and MSRRA: a service member's home-of-record does not change solely because military orders station them in New Hampshire, and an accompanying spouse can generally elect the service member's domicile state under MSRRA. Because New Hampshire taxes no individual income, choosing it as home-of-record eliminates state income tax on military pay entirely.

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.

In New Hampshire

New Hampshire has no major hub airport for airline crew, but the federal carve-out (49 U.S.C. § 40116, taxing crew wages only in the state of residence or a state where over 50% of pay is earned) combined with New Hampshire's lack of any income tax makes it, like Florida and Texas, a common domicile choice for crew based at nearby Boston Logan who want to avoid Massachusetts income tax on their wages.
