The most common question we get, answered honestly. A phone left behind does not buy you Florida days. It buys you a contradiction. Here is why a record that cannot be gamed is the only kind worth keeping, and what to do if you and your spouse both need 183 days.

New York and Florida are the two ends of the biggest tax migration corridor in America. The full side-by-side — income, capital gains, property, sales, and the estate tax cliff — and what the move is actually worth at your income level.

California and Florida sit at opposite ends of the state tax spectrum. Here's the full side-by-side — income, capital gains, property, sales, and estate — and what the gap is actually worth at your income level.
Can you have dual residency in Florida and another state? You can own homes in both — but tax law forces a choice. Here's how dual residency actually works, the statutory-resident trap, and how to make Florida win.
There is no single form that makes you a Florida resident. Here's how to declare residency in Florida the right way — the Declaration of Domicile, driver's license, voter registration, homestead, and the day count that backs it all up.
No — Florida taxes none of it. No tax on Social Security, pensions, 401(k) or IRA withdrawals, annuities, or investment income. Here's what that's worth, what you still owe federally, and what it takes to actually claim Florida's zero.
What are the actual requirements to become a Florida resident? The 6-month (183-day) presence test is only one of them. Here are the real requirements — presence, domicile, documentation — by purpose: taxes, homestead, tuition, and driver's license.
Legally, one day — Florida has no waiting period. Practically, the paperwork takes a month, tax protection takes 183 days, and tuition takes 12 months. The real timeline, purpose by purpose.
The return to Florida is the residency year's second act, and the date you pick for it decides more than the weather you get. The day-count salvage math, the paperwork that expires while you're away, the audit-file housekeeping, and why this is the one calendar decision worth making in August instead of October.
The retiree's version of the Florida tax math is full of surprises in both directions. Illinois and Pennsylvania already exempt most retirement income — while Minnesota and California tax nearly all of it. Before you count your savings, find out which kind of state you're leaving. The honest state-by-state picture, and the parts of the case that don't depend on income tax at all.
It arrives two or three years after the move — a polite letter from your former state asking you to complete a residency questionnaire. What follows has a predictable anatomy: the questionnaire, the document demands, the day-count battle, the domicile narrative, and the settlement table. Here's the whole arc, stage by stage, and what decides it at each step.
Everyone knows the number is 183. Almost nobody knows what a 'day' is — and that's where residency cases are actually won and lost. The layover, the midnight landing, the drive-through, the hospital stay, the travel day in each direction: every one of them has a rule, the rules differ by state, and auditors know them cold. Here's the day-counting law nobody reads until the audit.
Pennsylvania's 3.07% flat income tax is the lowest in this series — and Pennsylvania retirees pay essentially nothing on pensions, IRAs, and Social Security. So why is the PA-to-Florida corridor so busy? An inheritance tax that starts at dollar one, Philadelphia's wage tax, and a statutory residency test that works like everyone else's. The Pennsylvania move has the strangest math in the series; here it is.
The single most expensive residency mistake isn't a blown day count — it's sequencing. A founder who sells the company and then moves to Florida hands their state a percentage of the largest transaction of their life. The one who completes the move first, properly and with margin, keeps it. Here's the timing logic, the trap doors, and why the audit is guaranteed either way.
Ask anyone at a Florida cocktail party how residency works and you'll hear the same formula: spend six months and a day in Florida and you're safe. It's the most repeated sentence in the migration — and it's wrong in three different directions. Here's what the folk rule gets right, what it dangerously omits, and the version you should actually operate by.
Michigan's flat 4.25% rate looks gentle next to New York or Minnesota — which is exactly why the Michigan-to-Florida move gets planned casually and executed sloppily. Between city income taxes, the principal residence exemption, property tax uncapping, and a 183-day statutory test most snowbirds have never heard of, the details carry more money than the headline rate.
The classic snowbird season — November through April — is only 181 days. The 183-day year is won or lost in the summer, when you're a thousand miles from Florida and every wedding, holiday, and extra week at the lake quietly spends a day you may need in December. Here's the mid-year math.
Minnesota combines a 9.85% top income tax rate, a surtax on investment income, an estate tax with a $3 million exemption, and the most methodical residency auditors in the country — a 26-factor domicile test, applied by a Department of Revenue that has been litigating snowbird cases for decades. Here's what the move actually saves, and what Minnesota does about it.
A direct comparison of the day-counting tools available for state tax residency. What each one is built for, what each one costs, where each one fits — and where the honest tradeoffs are.
New York residency auditors don't take your word for where you lived. They build an independent record from cell records, EZ-Pass logs, credit card geolocation, doorman interviews, and a dozen other sources. Here's the playbook, in detail.
Connecticut to Florida is one of the most established tax migration corridors in the country, with Greenwich and Fairfield County leading the way. Here's what the move actually saves, how Connecticut challenges it, and how to make it stick.
A Florida residency claim is only as good as the day-count record behind it. Auditors test that record against cell tower data, credit card geolocation, and EZ-Pass logs. Here is what a defensible record actually looks like — and why most people do not have one.
When Ken Griffin moved Citadel's headquarters from Chicago to Miami in June 2022, he set the reference point for a generation of Illinois wealth departures. The move was about crime, business climate, and tax trajectory — and it has become the template for a larger migration that has not slowed.
On Tax Day 2026, Mayor Zohran Mamdani announced New York City's first-ever pied-à-terre tax — an annual fee on non-primary residences valued above $5 million. Here is what the tax does, why the Ken Griffin backdrop matters, and what it changes for anyone keeping a New York apartment as a Florida domiciliary.
A practical guide for spouses living in different states: separate travel records, New York filing choices, California community property, and questions for your advisor.
Illinois has one of the lowest estate tax exemptions in the country, not indexed to inflation, with rates up to 16% and no portability between spouses. For wealthy Illinois families, it is often a larger lifetime tax cost than the income tax. Here is how it works and why Florida is the fix.
The complete action plan for establishing Florida tax residency. File the right documents, move the right ties, and build the audit defense record that protects you if your former state comes calling.
Illinois has a flat income tax, one of the lowest estate tax exemptions in the country, and property taxes second only to New Jersey. Here's what a move to Florida actually saves, what Illinois does to contest it, and how to make it stick.
A contested domicile audit can cost $100,000–$300,000+ in legal fees, back taxes, and penalties — and take four years to resolve. Here's what actually triggers an audit, what auditors look for, and why contemporaneous records are your cheapest insurance.
New York's top combined rate already hits 14.8% for city residents. Now Albany is pushing further — pied-à-terre taxes, high-earner surcharges, an expanding audit bureau. Here's why 2026 is different, and why more high earners are leaving now than at any point in the past decade.
Owning homes in Florida and another state creates probate, tax, and heirship complications most people don't see coming. Here's what actually happens.
Massachusetts' 4% Fair Share surtax on income above $1 million took effect in 2023 and is now fully operational. For high earners — especially those in biotech with equity that can spike in a single year — the math on Florida residency has changed permanently.
New York doesn't have a formal exit tax — but it has something worse. Here's what NY-source income you still owe taxes on after establishing Florida residency.
Florida is one of 38 states with no estate or inheritance tax. For high-net-worth individuals, establishing Florida domicile can protect millions in wealth transfers.
The Florida homestead exemption saves new residents thousands per year in property taxes — and it's one of your strongest pieces of evidence in a residency audit. Here's exactly how it works.
New Jersey has the highest property taxes in the country, a top income tax rate of 10.75%, a burdensome real estate exit withholding requirement, and a Division of Taxation closely connected to New York's audit apparatus. High earners who have been watching the exit are now taking it.
Working remotely from Florida for an out-of-state employer? Here's how remote work affects your tax residency, what traps to avoid, and how to protect your Florida status.
California's Franchise Tax Board is more aggressive than New York's when it comes to auditing departing residents. Here's what you actually save, what California does to challenge it, and how to make the move stick.
Washington just passed its first income tax in 93 years. California and New York are pushing higher rates. New Jersey and Connecticut are circling. A historic convergence of state tax pressure is accelerating high-net-worth migration to Florida — and the window to act may be narrowing.
California is pushing a wealth tax on unrealized gains — and its Franchise Tax Board has every incentive to pursue people who leave. If you're a high-net-worth California resident considering a move to Florida, the window to leave cleanly is narrowing.
Washington State just passed its first income tax in 93 years — a 9.9% hit on income over $1M. For Amazon and Microsoft employees, founders, and executives in Seattle, the calculus on Florida just changed overnight.
You moved to Florida and filed all the paperwork. But if you spend 183 days in your old state and keep a home there, you could still owe taxes as a statutory resident.
