Short answer: moving to Miami from New York saves you real money — a single NYC resident with US$300,000 of taxable income pays roughly US$29,400 a year in New York state + city tax, and US$0 in Florida. But New York doesn’t take your word for it. The state runs one of the most aggressive exit-audit programs in the country: two separate tests — domicile and the 183-day statutory residency rule — decide whether you still owe tax on your worldwide income, and auditors rebuild your calendar from E-ZPass records, credit-card statements and cell data. Moving south is the easy part; proving you moved is the job.

How the New York exit audit works: the two tests
New York catches leavers with two independent tests — fail either one and you pay New York tax as a resident for the full year, on all your income no matter where it was earned.
1. The domicile test. Domicile is the place you intend as your permanent home. Here the burden of proof is on you: New York presumes you never left, and you must overcome that presumption with clear and convincing evidence — contemporaneous calendars, credit-card records, moving paperwork. The state’s Nonresident Audit Guidelines (December 2021 edition) score five primary factors: your Home (which residence you treat as home), Active Business Involvement (day-to-day management of a New York business often decides the case), Time (where you actually spend your days), Items Near and Dear (art, keepsakes, family photo albums), and Family Connections (where your closest family lives). Auditors compare each factor in New York against the same factor in Florida.
2. The 183-day statutory residency test. Even if you win the domicile argument, you are still a New York resident for the year if you keep a permanent place of abode in New York for substantially all of the year and spend more than 183 days there — partial days count, and the test applies in the year you move (NY Tax Law §605(a)(2)). One Manhattan pied-à-terre you can walk into any night can be enough to trigger it.
The five-factor scorecard auditors actually use
Tax practitioners summarize the audit as a single question: if someone woke you up at 3 a.m. and asked whether you’re a New Yorker or a Floridian, what would you answer? Auditors build the answer from the five factors — here is what they check, and what a clean Miami move looks like:
| Factor | What the auditor checks | What a clean move looks like |
|---|---|---|
| Home | Size, value and maintenance of each residence; which one you treat as home; whether you severed roots in the old community | Miami home is the primary one; NY place sold, leased out, or kept as a clearly secondary guest unit |
| Business | Active involvement in a New York business — often the deciding factor; a passive investment alone is not | Management and decision-making moved with you; NY role resigned or reduced to a passive interest |
| Time | Day-by-day calendar, cross-checked against E-ZPass, credit-card and cell records | Well under 184 days in New York, documented contemporaneously |
| Near and dear | Where the art, keepsakes and valuables actually hang | Collections and sentimental items moved to the Miami home |
| Family | Where your closest family members live and gather for holidays | Center of family life demonstrably in Florida |
What triggers a New York exit audit
New York doesn’t audit every leaver — it audits where the money is. Practitioners report the highest-risk profiles: high-income earners whose departure costs the state real revenue; a move in the same year as a business sale or large capital gain; people who keep a New York residence, club memberships or board seats; and remote workers whose employer is in New York (more on that below). The state has pursued leavers aggressively for years — and a couple who bought a Naples condo, registered their cars in Florida, voted in Florida and moved their belongings still ended up with a ~US$60,000 tax bill upheld after keeping New York paychecks and club memberships (a case widely covered by tax practitioners). Signing a grocery-store loyalty card in Miami is not a defense; auditors want to see the big ties moved.
What most people don’t know
183 days is necessary, not sufficient. Staying under 184 days in New York defeats the statutory test — but the domicile test can still catch you if your business, family and keepsakes still live in New York. Clear the day count AND the five factors.
The move year is the danger zone. The statutory test applies to the taxable year in which your domicile changes. A sloppy calendar in year one can cost you a full year of New York tax on everything.
Remote work for a New York employer may still be New York wages. Under New York’s convenience-of-the-employer rule, wages from a New York employer can remain taxable by New York even when you work from a Miami apartment — unless the remote arrangement is a business necessity of the employer. This surprises more movers than any other rule.
A hospital stay doesn’t count — but your spouse’s visit does. Days in New York for inpatient medical care are excluded from the count; days your spouse spends visiting you there are not. Details like that are why practitioners insist on a contemporaneous day-by-day calendar.
Voting in New York after “leaving” is a red flag. Voter registration is one of the cleanest objective ties. Register in Florida, surrender the New York license, and make the paperwork match the story.
The Miami playbook: making your move audit-proof
This is where SETTLE’s view differs from a tax article’s: the audit is won in the first 30 days, with logistics. File a Florida homestead exemption (deadline: March 1 of the following year), get the Florida driver’s license, register vehicles and voter registration in Miami-Dade, update wills and trusts to a Florida address, move bank and brokerage accounts, resign New York clubs and boards, and — the part movers skip — move the near-and-dear items: art, photo albums, the things that make a house a home. Keep a day-by-day calendar from day one. Our first New York piece priced the savings at up to US$29,400 a year for a single NYC resident at US$300,000 of income; an audit you lose costs that plus penalties and interest. The domicile checklist we prepare with every New York client exists for exactly this reason.
Moving to Miami from New York: does the cost of living in Miami still win?
Yes — and it’s not close on taxes alone. Florida’s 0% income tax versus New York’s 2026 brackets of 3.9% to 10.9% (state) plus 3.078% to 3.876% (New York City, resident tax) is the headline. But the full cost of living in Miami picture matters too: no state withholding means your paycheck is bigger from month one, which is exactly why New York is the #1 origin state for Florida newcomers — 23,436 New Yorkers traded a New York license for a Florida one in the first half of 2026 alone (Florida DHSMV data via Florida Realtors, reported August 2026). Between 2018 and 2022, more than 125,000 New Yorkers moved to Florida, taking about US$14 billion of income with them (Citizens Budget Commission). Every one of them had to answer the same question you’re answering now: not just can I afford the move, but can I prove it.
Frequently asked questions
Does the 183-day rule apply in the year I move?
Yes. The statutory residency test applies to the taxable year in which your domicile changes, so your move year is audited under both tests. A clean calendar starting on day one is the single highest-value document you can keep.
I kept my Manhattan apartment but spend 200 days a year in Miami. Am I safe?
Maybe on the day count (under 184 days in New York defeats statutory residency), but not on domicile. Auditors compare the residences — if the New York place is bigger, nicer and more maintained, it looks like home. Most practitioners advise selling, leasing out, or clearly demoting the New York residence.
I never filed a New York return after moving. Can they still audit me?
Practitioners’ standard advice: the clock on the statute of limitations generally doesn’t start on a return you never filed. File a final part-year resident return for the move year, then keep your domicile evidence for years — audits often arrive two or three years later.
I work remotely from Miami for my New York employer. Do I owe New York tax?
Quite possibly yes, on the wages. New York’s convenience-of-the-employer rule keeps wages from a New York employer taxable by New York when you work remotely by choice. This is separate from the exit audit and catches people who thought the move ended their New York tax bill.
