A 63-year-old couple retires from investment banking, sells their second home in the Hamptons, keeps the Manhattan co-op, buys a condo in Naples, and assumes their tax situation just became dramatically simpler. Then a letter arrives from the New York State Department of Taxation and Finance asking why they failed to file as New York residents.
This is one of the most common and expensive misunderstandings among affluent retirees. In late 2025, a New York couple lost a domicile-change case before the Tax Appeals Tribunal despite purchasing a Florida home, registering to vote there, and spending more time in Florida than in New York. The Tribunal applied what tax attorneys refer to as the “clear and convincing evidence” standard, and the couple failed to meet it. The same outcome can happen to retirees who treat snowbirding as a tax strategy without making the deeper structural changes necessary to establish a true change of domicile.
The Snowbird Situation in Plain Numbers
- Ages: Both 63, recently retired
- Liquid and retirement assets: $4.3 million across IRAs, brokerage, and a small federal pension
- Real estate: $1.8 million Manhattan co-op and a $920,000 Naples, Florida condo
- Annual income: Roughly $300,000 of IRA and pension distributions plus $80,000 of consulting fees and dividends
- The core issue: They believe they owe zero state income tax. New York may disagree.
Why New York Can Still Tax You
New York Tax Department Publication 88 outlines two separate residency tests, and failing either one can leave a retiree owing full New York state income tax on all taxable income, including IRA withdrawals, pension payments, brokerage gains, and even out-of-state consulting income.
The first is the domicile test, which examines where a person’s life is actually centered. The second, and often more dangerous for snowbirds, is the statutory residence test. If a retiree maintains a “permanent place of abode” in New York, meaning a year-round residence available for personal use, and spends more than 183 days in the state, New York can classify that person as a full-year resident regardless of where a driver’s license or voter registration is located.
A Manhattan co-op available year-round is the classic example. On roughly $380,000 of combined annual income, a statutory residency determination can generate approximately $22,000 to $28,000 in New York state income tax each year, depending on the bracket mix. If audit records show sufficient time spent inside New York City, city income taxes can add another 3% to 4%. Across a 25-year retirement, that single residency mistake can realistically pull more than $500,000 out of a portfolio.
The broader tax gap between New York and Florida is substantial. New York’s state-local tax burden adjusted for income is estimated at roughly $10,828 per capita, among the highest in the country, while Florida’s sits near $5,110. The State Tax Competitiveness Index ranks New York near the bottom nationally and Florida near the top. But retirees only receive those Florida tax advantages if they successfully establish and maintain residency under the rules New York actually enforces.
This Is How You Fix It
For most couples in this position, half measures lose. The strongest path is also the most disruptive.
- Sell the Manhattan co-op or convert it to a genuine investment property. Selling eliminates the “permanent place of abode” entirely. Converting requires a documented LLC structure, an arm’s-length lease to an unrelated tenant, and no personal use beyond the days the lease permits. Casually letting your daughter live there rent-free does not qualify.
- Build a Florida domicile that survives scrutiny. Driver’s licenses, voter registration, primary care physician, estate documents, primary banking, club memberships, and the homestead exemption on the Naples condo all need to point to Florida. New York auditors weigh the “five primary factors”: home, business activity, time, near and dear items, and family connections. Half a Florida life is treated as a New York life.
- Keep meticulous day-count records and hire a dual-state CPA before filing. Calendar apps, EZ-Pass logs, credit-card geolocation, and cell-tower data are all fair game for auditors. Anyone trying to live under 184 New York days needs contemporaneous proof, not a memory test two years later.
Option one is the cleanest. Option two without option one rarely wins. Option three alone almost never wins because the Manhattan co-op keeps the statutory residence door open.
What to Do First
Run the numbers on the Manhattan co-op honestly. If using the property for only 100 days a year creates $22,000 to $28,000 in avoidable New York taxes, on top of maintenance fees, property taxes, and potential New York City tax exposure, the co-op is effectively imposing its own recurring cost against the retirement portfolio. In many cases, the realistic alternatives become selling the property, downsizing to short-term rentals during New York visits, or converting the co-op into an income-producing rental property.
The most common mistake retirees make is assuming that spending more than 183 days in Florida automatically solves the residency issue. It does not. The statutory residence test operates independently from domicile rules, and maintaining a year-round New York residence keeps the tax exposure alive regardless of how much time is spent on Florida beaches.
The point where professional advice becomes financially worthwhile is surprisingly low. If the combination of New York real estate holdings, New York-sourced income, and time spent in the state could expose a retiree to more than roughly $20,000 a year in disputed taxes, hiring a fee-only CPA experienced in New York residency audits can easily pay for itself during the first filing cycle alone.
