AT A GLANCE
- New York’s estate tax exemption is $7,350,000 in 2026, well below the federal exemption
- Domicile is determined by intent and behavior, not paperwork or mailing address
- Even with a valid domicile change, maintaining a NY home and spending more than 183 days in state can trigger income tax as a statutory resident
- New York auditors examine five factors: home, time, personal property, business activity, and family connections
- A successful domicile change requires years of consistent, documented behavior
Since the federal estate tax exemption increased significantly in recent years, we hear a version of the same question from clients with substantial wealth: should I just leave New York?
It is a fair question. New York imposes both a state estate tax and some of the highest income taxes in the country. For families with significant assets, the annual savings from moving to a no-income-tax state can be substantial, and the estate tax savings at death can reach seven figures. The math is not complicated.
But the execution is. New York employs dedicated auditors whose entire job is to determine whether people who claim to have moved actually did. The state wins more than half of those audits.
This guide explains what domicile actually means, what the state looks for, and what a credible change requires.
WHAT IS AT STAKE
New York taxes residents on worldwide income at a top state rate of 10.9%. New York City residents add another 3.876%, bringing the combined rate to nearly 15%. Florida, Texas, and several other states impose no income tax at all.
For a family with $2 million a year in investment income, that difference can approach $300,000 annually in income tax alone, before estate taxes enter the picture.
On the estate side, the gap is even more striking. New York’s estate tax exemption in 2026 is $7,350,000. Estates above that threshold are taxed at rates up to 16%. Florida has no estate tax. Neither does Texas or Nevada. The federal exemption is now $15 million per person, which means the $7.65 million gap between the federal exemption and New York’s threshold is fully exposed to state estate tax for families who remain domiciled in New York.
For a $20 million estate, a successful domicile change to Florida can eliminate $1.5 to $2 million in state estate tax, depending on structure. That number grows with the size of the estate.
DOMICILE IS NOT YOUR ADDRESS
This is the most important thing to understand, and the source of most failed claims.
Domicile is the state you intend to be your permanent home. You can own properties in ten states. You have one domicile. It is determined not by where your mail goes or where you are registered to vote, but by where you have actually centered your life.
Statutory residency is a separate concept, and it creates a second trap. Even after successfully changing domicile to another state, New York can still tax you as a statutory resident if you maintain a permanent place of abode in New York and spend more than 183 days in the state during the tax year. The domicile question and the statutory residency question are independent. You can win the first and still lose the second.
For estate tax purposes, domicile alone controls. If you are domiciled in Florida when you die, New York’s estate tax does not apply regardless of how much time you spent in New York in prior years or whether you still own property here. That is the cleaner win for estate planning purposes, though it requires the same foundation as the income tax change.
HOW NEW YORK EVALUATES A DOMICILE CLAIM
In a domicile audit, you bear the burden of proof. The state applies a five-factor test, and auditors gather objective evidence rather than relying on declarations of intent.
Home. Where do you actually live? Auditors compare your New York property to the property in your claimed new domicile: size, value, how much time you spend in each, and whether your behavior suggests you treat one as home and the other as secondary. Selling the New York property is the clearest signal. Keeping a larger or more valuable New York property while acquiring a modest Florida condo cuts against the claim.
Time. Auditors request cell phone records, credit card statements, EZ-Pass data, travel logs, and sometimes social media activity. They look at patterns over multiple years, including where holidays and significant personal events are spent. Day-count tracking from the date of the claimed move is not optional.
Personal property. Where are your most significant possessions? Auditors look specifically at art, jewelry, family heirlooms, and high-value personal items. They pull insurance riders to verify location. If the items that matter most to you are still in your New York home, that is evidence your New York home is still your real home.
Business activity. Where is your professional and economic life centered? This factor focuses on active involvement: where you attend meetings, where decisions are made, where your professional relationships are maintained. Passive investment income carries little weight here.
Family connections. Where does your immediate family live? If a spouse or minor children have not relocated, auditors treat that as strong evidence against the domicile claim. Where you spend holidays and family gatherings also matters.
WHAT NEW YORK COURTS HAVE SAID
In Matter of Obus v. New York State Tax Appeals Tribunal (2022), the Appellate Division addressed what qualifies as a “permanent place of abode” for statutory residency purposes. Nelson Obus, a New Jersey domiciliary, owned a vacation home in Northville, Fulton County, more than 200 miles from his workplace, and used it roughly three weeks a year for skiing and visits to the Saratoga racetrack. New York treated him as a statutory resident based on ownership alone.
The court ruled in his favor. To constitute a permanent place of abode, there must be a showing that the taxpayer has a genuine “residential interest” in the property and uses it as a residence. Owning a vacation home, by itself, is not enough.
Obus was a meaningful taxpayer win, but it is a fact-specific decision. The state still audits residency claims aggressively and the burden of proof remains on the taxpayer. The lesson is not that vacation homes are safe; it is that the residential character of the property matters, and that character is established through use, possessions, family activity, and the role the property actually plays in your life.
WHAT A CREDIBLE DOMICILE CHANGE ACTUALLY REQUIRES
Administrative steps are necessary but not sufficient. A Florida driver’s license and a change of voter registration establish intent on paper. Auditors look past paper.
A credible domicile change involves moving your actual life. That means acquiring a home in the new state that is genuinely larger, more valuable, or more central to your daily activity than any New York property you retain. It means relocating the personal possessions that matter most: art, jewelry, family items. It means shifting primary medical care, legal counsel, financial advisors, and professional memberships to the new state where possible.
It also means spending more time in the new state than in New York, documenting that time contemporaneously, and keeping the New York day count below 183 if income tax exposure is also a concern.
Estate planning documents should be updated to reflect the new domicile: will, trust instruments, beneficiary designations, and powers of attorney. Some New York trust structures carry their own state tax exposure that does not automatically move with the grantor’s domicile, so existing arrangements should be reviewed before the transition is treated as complete.
A SITUATION WE SEE OFTEN
A client came to us after receiving a residency audit notice covering two prior tax years. He had declared Florida domicile, obtained a Florida driver’s license, and filed Florida returns. What he had not done was move his primary home, his art collection, his family, or his professional life. His New York apartment remained his largest property. His children were in New York schools. His business meetings continued to happen in New York. He had been in the state well over 183 days in each of the audited years.
The paperwork said Florida. Everything else said New York. He lost.
The cost was not just the back taxes. It was penalties, interest, and legal fees on top of a result that proper planning could have avoided entirely.
THE NEW JERSEY ALTERNATIVE
Not every client’s question involves moving far. Some families are already spending significant time in New Jersey and are weighing whether a formal domicile change to NJ makes sense.
New Jersey repealed its estate tax in 2018. A New Jersey domiciliary currently pays no state estate tax. However, New Jersey retains an inheritance tax on transfers to certain beneficiaries, with rates and exemptions that depend on the relationship between the deceased and the recipient. The rules differ significantly from New York’s.
New Jersey domicile planning solves the estate tax problem but does not eliminate all state-level transfer tax exposure. And it carries the same audit risk as any domicile change. The move has to be real.
WHEN TO START THIS CONVERSATION
Domicile planning is not a crisis decision. It is a strategy that takes time to execute correctly and years to build against audit scrutiny.
The right moment is before a major transition: before you sell the business, before a year when you know you want to spend significant time in New York, before the estate has grown into the range where the exposure becomes significant. Clients who start early have the most options. Clients who come to us mid-audit have far fewer.
If you have been asking the question, that is reason enough to have the conversation now.
