A snowbird deliberately keeps ties to two states rather than cutting them, which means the planning problem is different from establishing Florida domicile. New York’s rule illustrates the stakes: someone who keeps a New York home available for substantially all of the year (under current audit policy, more than ten months) and spends more than 183 days in the state is a statutory resident taxed on worldwide income, full stop, with no domicile defense available. Auditors reconstruct day counts from EZ-Pass records, credit card statements, and cell phone data, so the count has to be right, not approximately right.
This guide covers what actually changes for someone splitting time between two states rather than relocating fully: day-count management, Medicare coverage across state lines, and the insurance gap that opens when a Florida home sits empty for months at a time.
Quick Answer Snowbird financial planning centers on three ongoing management problems rather than a one-time domicile decision: tracking days accurately enough to survive an audit (states that use a 183-day statutory residency test generally count any part of a day, and keeping a home available “for the kids” still counts as maintaining a permanent place of abode even if unused), choosing Medicare coverage that actually works in both states (Original Medicare travels nationwide, but Medicare Advantage plans are generally restricted to a home-state network), and confirming homeowners insurance still applies once a home sits vacant, since most standard policies limit or void coverage after 30 to 60 consecutive vacant days. |
Why Snowbird Planning Is Different From Establishing Domicile
Someone establishing Florida domicile is trying to prove a former state’s ties have been abandoned. A snowbird is doing the opposite on purpose: keeping a home, family connections, or business ties in both places by design, often specifically to preserve the option of returning each year. That distinction matters because it changes which planning problem is actually being solved. Our guide to establishing Florida domicile covers the mechanics of a full move; this guide covers what stays in motion every year for someone who never intends to fully leave.
Getting the Day Count Right, Every Year
States that apply a day-count-based statutory residency test generally treat any part of a day spent in the state as a full day. A short layover, a few hours driving through on the way somewhere else, still counts in many states’ methodology. New York’s specific combination, a permanent place of abode kept for more than ten months plus more than 183 days physically present, creates statutory residency regardless of where domicile has been established, and there is no domicile-based defense once both thresholds are crossed.
Auditors do not take a taxpayer’s word for the count. Cell phone location records, EZ-Pass toll data, credit card statements, and even social media posts are used to reconstruct where someone actually was on a given day, and undocumented days are generally counted against the taxpayer rather than in their favor. The practical implication is that a snowbird’s day count needs to be tracked contemporaneously, as the year happens, rather than reconstructed from memory the following spring when a CPA asks.
Medicare Coverage That Actually Follows a Snowbird
Original Medicare (Parts A and B) provides nationwide coverage as long as the provider accepts Medicare assignment, and it requires only that one primary address be kept on file with Social Security for official correspondence. Medicare Advantage (Part C) works differently: because private insurers administer these plans, coverage is generally built around a network tied to the beneficiary’s primary residence, and a plan available in the winter state may not include in-network providers in the summer state, or at all.
Medigap (Medicare Supplement) policies are enrolled based on the policyholder’s primary residence but generally provide coverage anywhere Original Medicare is accepted, which is why Original Medicare plus a Medigap policy is commonly recommended over Medicare Advantage specifically for people who split time between two states. A Medicare Advantage enrollee who wants to keep that coverage type needs to specifically evaluate network breadth, PPO plans with national provider access generally travel better than HMO plans, and confirm what happens to coverage if time away from the plan’s service area extends for months rather than weeks.
The Insurance Gap Most Snowbirds Don’t Know Exists
A standard Florida homeowners policy is written around continuous occupancy, and most policies include a vacancy clause that limits or entirely suspends specific coverages, commonly theft, vandalism, and water damage, once a home has sat vacant for 30 to 60 consecutive days. A snowbird home that’s empty for four to six months a year routinely exceeds that window.
The distinction insurers draw matters here: an “unoccupied” home that stays furnished, maintained, and monitored while the owner is away is generally treated differently than a fully “vacant” home that’s been emptied out, and a seasonal or second-home policy is often the better fit for a furnished home used part of the year rather than a true vacant-property policy. What matters most is disclosure. Not telling the carrier that a property is used seasonally rather than as a primary residence is generally treated as a material misrepresentation, and a claim on an undisclosed seasonal property can be denied even if the loss itself would otherwise have been covered. In Florida specifically, that gap compounds with hurricane season, since June through November is exactly when many snowbird homes sit emptiest.
Common Mistakes in Snowbird Planning
Assuming a Florida driver’s license and voter registration settle the tax question. Those steps support a domicile claim, but a snowbird who still crosses a former state’s day-count threshold can owe tax as a statutory resident there regardless of where domicile has been established.
Counting days loosely. Treating a travel day, a layover, or a quick drive through a state as not counting is one of the most common ways a day count comes up short during an audit.
Assuming Medicare Advantage travels the same way Original Medicare does. Network restrictions can leave a snowbird with limited or no in-network coverage in the second state.
Not telling the insurance carrier about seasonal use. An undisclosed vacancy pattern is one of the more common reasons a claim gets denied on a Florida seasonal home.
Frequently Asked Questions
It depends on the state, but many states that use a day-count test set the threshold at 183 days, often combined with maintaining a permanent place of abode there for a substantial part of the year. Crossing both thresholds generally triggers statutory residency regardless of where domicile is otherwise established.
Yes. Original Medicare (Parts A and B) provides nationwide coverage with any provider who accepts Medicare assignment. Medicare Advantage plans are different, since they're administered by private insurers around a network generally tied to one primary residence.
Not automatically. Most standard homeowners policies limit or suspend key coverages after 30 to 60 consecutive vacant days, which many snowbird absences exceed. A seasonal or second-home policy, disclosed accurately to the carrier, is generally the more reliable option.
Not necessarily. Many snowbirds intentionally maintain ties to both states rather than fully establishing domicile in either. The planning problem for a snowbird is managing day counts and dual-state logistics on an ongoing basis, distinct from the one-time process of establishing and documenting a full domicile change.
Boarding passes, EZ-Pass or toll records, credit card and banking statements showing location, and a contemporaneous log of travel dates are the kinds of records auditors expect to see, since records created at the time of the event carry more weight than ones reconstructed later.
Where This Fits Into a Broader Financial Plan
Snowbird planning touches tax exposure, healthcare coverage, and property risk at the same time, and each of those pieces tends to be handled by a different professional who may not be talking to the other two.
