Snowbird Retirees With $3.2 Million Must Choose Residency Carefully

Splitting the year between a paid-off colonial north of Boston and a condo near Siesta Key, Fla., sounds idyllic. The complication is figuring out which state gets to tax the income and, eventually, the estate.

Consider the example of a married couple, both 67, with $3.2 million across retirement and taxable accounts. They own a house in Massachusetts and a condo in Sarasota, spending roughly six months in each. They draw about $130,000 of taxable retirement income a year, well inside the 22% federal bracket for married couples filing jointly in 2026 (which runs from $24,800 to $100,800 at 12%, then up to $211,400 at 22%). After the $32,200 standard deduction, the federal hit is fairly predictable.

The state side is where real money is on the table. This situation shows up constantly in r/retirement and r/Bogleheads threads.

The Residency Question Is the Whole Ballgame

Massachusetts and Florida sit on opposite ends of the retiree tax spectrum. Massachusetts charges a 5% flat state income tax, plus a 4% surtax on income above $1 million, and levies a tax on estates above $2 million. Florida charges zero state income tax and has no estate tax.

On $130,000 of retirement income, declaring Florida residency saves the couple roughly $6,500 a year in Massachusetts income tax. But the estate piece is larger. A $3.2 million estate for a Massachusetts resident faces state tax of roughly $120,000. The federal estate exemption for couples sits at $30 million in 2026, so our couple wouldn’t be affected.

Cost of living adds a smaller tailwind. Florida is a lot more expensive than it used to be. Massachusetts carries a regional price index of 106 versus Florida at 103, so day-to-day expenses in the Sunshine State run a little cheaper.

Establishing Florida domicile takes more than a calendar count. The state wants to see 183-plus days in Florida plus clear intent: voter registration, driver’s license, banking relationships, and a declaration of domicile. Massachusetts is famously aggressive about auditing departing residents, pulling EZ-Pass records, cell tower data, and credit card statements to argue the taxpayer never really left.

Three Options for This Snowbirding Couple

1. Full Florida domicile, kept clean. Spend at least 183 days in Sarasota, register to vote there, switch driver’s licenses, move primary banking and brokerage addresses, file a Florida Declaration of Domicile, and downgrade the Massachusetts house to a clearly secondary residence. This captures both the income tax and estate tax savings.
2. Stay Massachusetts-domiciled. Simpler, no paperwork drama, and you keep your doctors and voting precinct. You also keep writing checks to the Department of Revenue every April and your heirs eventually write a much larger one. Choose this only if the Massachusetts house genuinely is your center of life.
3. Try to game the calendar without changing intent. This is the trap. Spending 184 days in Florida while keeping your MA driver’s license, voter registration, and primary doctor could trigger a residency audit, and Massachusetts wins those audits routinely.

What to Do First

Pick the domicile question and commit. If Florida is the answer, complete the paperwork and draw up a new estate plan drafted under Florida law. Keep a contemporaneous day log every year showing where you slept each night. Massachusetts auditors lose when the calendar is documented and the intent paperwork is airtight.

The single most expensive mistake is the half-measure: spending most of the year in Florida while leaving Massachusetts fingerprints on your life. That posture costs the income tax savings and risks the estate tax savings too. Given the $2 million Massachusetts estate threshold and a $3.2 million net worth, a fee-only estate attorney licensed in Florida is not a bad idea.
