Connecticut Residency

DRS regulations direct examiners to weigh your real estate, business, social, and civic connections to Connecticut against those in your other states, without a strict day-count shortcut. Daniels v. Commissioner of Revenue Services involved exactly this fact pattern, and a Superior Court initially found the Connecticut and Florida ties roughly equal, which meant the outcome turned on which side had the burden of proof and how high that bar was set, not on a single deciding factor.

No published Connecticut safe harbor of that kind exists. Connecticut's statutory residency test is the same 183-day-plus-permanent-abode formula used elsewhere, but the state has not enacted a separate carve-out for domiciliaries working outside the country the way New York has with its 548-day rule. Anyone relying on extended foreign work to avoid Connecticut residency should plan around the general domicile and 183-day tests rather than assume an equivalent safe harbor exists.

Yes, and this is precisely what happened in Daniels v. Commissioner of Revenue Services. DRS audited the estate, found Connecticut domicile despite the decedent's time split among Connecticut, Arizona, and Florida, and the fight over which state got to tax the estate continued for years after death. The 2026 Connecticut Supreme Court decision made it somewhat easier for an estate to win this kind of dispute by lowering the burden of proof, but it confirms Connecticut treats a genuinely divided retirement lifestyle as a real audit target, not a hypothetical one.

Yes, and Connecticut residents are the test case for this exact question. Cardozo Law School professor Edward Zelinsky, a Connecticut resident who teleworks for a New York City employer, has litigated New York's convenience of the employer rule for years; the New York Tax Appeals Tribunal upheld the rule against him again in May 2025. Unless your remote work meets New York's narrow necessity exception, New York can tax your full salary as if you worked in its office every day, even though you never leave Connecticut.

Yes, since 2019. Connecticut taxes a nonresident who works remotely for a Connecticut-based employer as if they worked in Connecticut, but only if that nonresident's home state also imposes its own convenience rule on Connecticut residents, which today means New York. If you work remotely for a Connecticut employer from a state without a convenience rule, Connecticut generally does not apply this rule to you.

Not by itself. Connecticut's own regulations distinguish a genuinely temporary, work-related apartment from a permanent place of abode, and an apartment used only for limited work purposes, even for a stretch exceeding 183 days of physical presence, has been treated as falling outside the statutory residency test because it isn't permanent. The distinction depends heavily on the facts, including lease length, how the space is furnished and used, and whether it functions as anything close to a real home.

DRS generally has three years from the date you filed a return to assess a deficiency, under Conn. Gen. Stat. §12-733. Once a liability is assessed or self-reported, Connecticut now has ten years to collect it, under a 2022 change to Conn. Gen. Stat. §12-35. Neither limit applies if you never filed a return or filed a fraudulent one, in which case there is effectively no time limit.

Your estate's executor will need to prove the Florida move was a genuine change of domicile, weighed against your real estate, business, social, and civic connections to Connecticut, and DRS's audit division actively reviews estates for exactly this. Daniels v. Commissioner shows the fight can happen years after death and go all the way to the Connecticut Supreme Court; the 2026 ruling in that case at least lowered the standard of proof an estate needs to meet, from clear-and-convincing to a preponderance of the evidence.

Yes. Connecticut taxes nonresident athletes and entertainers on income earned from Connecticut performances or events using duty-day style apportionment, the same general approach other states use for the jock tax. This applies to touring performers and visiting athletes at Connecticut's major casino venues, as well as to the home roster of the WNBA's Connecticut Sun, which is based at Mohegan Sun.

Practitioners generally rank Connecticut slightly below New York and California in overall audit intensity, but it is still consistently named among the handful of most aggressive states, alongside New York, California, New Jersey, and Maryland. Connecticut's revenue base is unusually concentrated among high earners in towns like Greenwich and Westport, and DRS reportedly audits departures to Florida at high rates, especially when a Connecticut home is kept, so treating it as a lower-risk state than New York would be a mistake.
