New York does not have an exit tax. There is no line item on your final return that says “leaving fee.” No percentage of your net worth is confiscated at the border.
But if you think moving to Florida means you are done paying New York taxes, you are likely wrong — and the gap between what people expect and what actually happens is where the problems start.
New York maintains taxing authority over certain categories of income regardless of where you live. The day you establish Florida domicile, you stop owing New York tax on your investment income, your retirement distributions, and your non-New York business income. But income connected to New York — and the definition of “connected” is broader than most people realize — follows you.
This is the de facto exit tax. It does not have a name, but it has teeth.
The Year You Leave: Part-Year Resident Filing
The mechanics of the move year itself catch people off guard.
If you were a New York resident on January 1 and establish Florida domicile on June 15, you do not file as a full-year non-resident. You file as a part-year resident using Form IT-203. New York taxes you as a full resident for the period January 1 through June 14, and as a non-resident for the remainder of the year.
During the resident portion, New York taxes your worldwide income — everything, from every source, just as it always did.
During the non-resident portion, New York taxes only your New York-source income. This is where the allocation rules become critical.
Income that straddles the move date requires careful allocation. A bonus paid in August for work performed January through July must be split between the resident and non-resident periods. Stock options exercised after the move but granted and vested during residency may be partially allocated to New York. Deferred compensation triggers complex sourcing analysis.
The part-year return is not a simple form. It is the most scrutinized return in the New York-to-Florida move because it establishes the exact date you claim the change happened — and auditors will test that date against every piece of evidence they can find.
Practical note: Choose your change-of-domicile date deliberately. It should align with the date you actually, physically moved your primary life to Florida — not the date you filed paperwork, and not an arbitrary date chosen for tax optimization. Auditors are skilled at identifying dates that were selected after the fact to minimize the resident-period tax bill.
What New York Taxes After You Leave
Once you are a Florida domiciliary and a New York non-resident, New York’s taxing authority narrows — but it does not disappear. Under New York Tax Law Sections 631 through 638, the state taxes non-residents on all income “derived from or connected with New York sources.”
The categories are specific and, in some cases, surprisingly broad.
Wages for Work Performed in New York
If you work in New York — physically present in the state performing services — those wages are New York-source income. This is straightforward: a day of work at a New York office is a day of New York income, regardless of where you live.
The allocation is typically based on a day count: the number of days worked in New York divided by total working days, applied to your total compensation. If you work 30 days in New York and 220 days total, roughly 13.6% of your salary is allocated to New York.
This matters for people who move to Florida but continue traveling to New York for work. Every day in a New York office generates New York-source income and a corresponding tax obligation.
The Convenience of the Employer Rule
New York’s most controversial sourcing rule does not require you to be in New York at all.
Under the convenience of the employer doctrine, if you work remotely for a New York-based employer, your work-from-home days in Florida may be treated as New York workdays — unless you can demonstrate that working remotely is a necessity of the employer, not your personal convenience.
The rule works like this: if your employer has a New York office where you could work, and you choose to work from Florida instead, New York considers those days as New York workdays for income allocation purposes. The only exception is when the employer requires you to work from another location for bona fide business reasons — a separate office, a client site, a territory assignment.
New York’s Tax Appeals Tribunal has upheld this doctrine repeatedly. The most recent significant decision is Matter of Zelinsky (May 15, 2025), in which the New York Tax Appeals Tribunal upheld the convenience rule against a law professor who worked remotely from Connecticut. The Tribunal held that even minimal in-state presence — as little as 10% of working days — satisfies due process, and that remote work chosen by the employee does not constitute employer necessity.
The practical effect: A Florida resident who works remotely for a New York employer, with no assigned New York office days, may still owe New York income tax on 100% of their salary. The domicile change saves nothing on that employment income unless the employer takes specific steps to establish that the remote arrangement is an employer necessity.
If this applies to you, the solution is structural: the employer must be able to demonstrate that you work from Florida because the business requires it — not because you moved there. This is a conversation with both your employer and a tax professional who understands this doctrine.
Real Estate Income and Gains
Rental income from New York property is New York-source income. If you own a Manhattan apartment that you rent out after your move, the net rental income is taxed by New York at the same rates that apply to residents.
Capital gains from the sale of New York real property are also New York-source income. If you sell your co-op or condo after establishing Florida domicile, the gain is taxable by New York. This is not a temporary rule or an aggressive interpretation — it is explicit in the statute under Tax Law Section 631(b)(1)(A). New York requires non-residents to file Form IT-2663 and remit estimated tax at closing, typically at 8.82% of the gain.
The timing of a property sale relative to your move is a legitimate planning consideration. But the gain is allocated to New York regardless of when you sell, as long as the property is located in New York.
Partnership and S-Corporation Income
This is where the reach of New York’s sourcing rules affects the most dollars for high-net-worth individuals.
If you are a partner in a partnership or a shareholder in an S-corporation that conducts business in New York, your share of that entity’s New York-source income is taxable by New York — even after you move to Florida.
Under Tax Law Section 632, the determination of New York-source income for partners and S-corp shareholders flows through from the entity level. If the partnership earns 40% of its income from New York activities, 40% of your distributive share is New York-source income.
For people who are partners in New York-based private equity funds, hedge funds, law firms, or other professional service firms, this rule means that a significant portion of their income remains taxable by New York indefinitely — or at least for as long as the entity continues to generate New York-source income.
This is not an audit risk. It is a filing obligation. The entity issues a Schedule K-1 with a New York allocation, and you report it on your non-resident return. It is mechanical, predictable, and unavoidable without changing the entity’s operations or your ownership interest.
Deferred Compensation and Stock Options
Compensation that was earned during New York residency but paid after you leave is subject to New York’s allocation rules.
Non-qualified stock options are allocated based on the ratio of days worked in New York between the grant date and the exercise date, relative to total working days in that period. If you were granted options while working in New York for three years, then moved to Florida and exercised them two years later, roughly three-fifths of the gain may be allocated to New York.
Restricted stock units (RSUs) follow a similar allocation — the period from grant to vest determines the New York fraction.
Deferred compensation plans (Section 457, non-qualified deferred comp) are allocated based on the period of service that generated the deferral. Compensation deferred during New York residency and paid out during Florida residency is partially New York-source income.
The allocation formulas are defined in New York’s regulations and are applied mechanically. They are not discretionary. If you have significant deferred compensation or unvested equity, the New York tax tail can persist for years after your physical departure.
How Much New York Collects From Former Residents
New York does not publish granular statistics on non-resident tax collections broken out by former residents specifically. But the scale of non-resident filing gives a sense of the revenue at stake.
The New York Department of Taxation and Finance collected over $3 billion from approximately 750,000 audits in the 2022-2023 period. For high-net-worth individuals specifically targeted by the Nonresident Audit Bureau in prior years, the average assessment was approximately $144,000 per successful audit. The Bureau has grown consistently over the past decade, reflecting the revenue it generates.
IRS Statistics of Income (SOI) migration data shows that New York consistently leads the nation in net outbound migration of adjusted gross income. In the most recent data available (2022-2023), 267,156 individuals on 140,246 returns left New York, representing $9.9 billion in adjusted gross income. Florida was the top destination, receiving nearly 262,000 individuals and $20.6 billion in total inbound AGI from all states.
These numbers represent people who successfully changed their tax filing state. They do not capture the ongoing New York-source income those same people continue to report on non-resident returns — the partnership allocations, the real estate income, the deferred compensation. That revenue stream is substantial and persistent.
The Income That Actually Goes to Zero
For all the categories above, there is a clear and important counterpoint: the income types that New York can no longer touch once you establish Florida domicile.
Investment income — dividends, interest, and capital gains from the sale of stocks, bonds, and other intangible assets — is sourced to your state of domicile. As a Florida resident, that income is not New York-source. For individuals whose income is primarily from investment portfolios, this is where the savings are concentrated and most meaningful.
Retirement distributions — pensions, 401(k) withdrawals, IRA distributions — are protected by federal law. Under 4 U.S.C. Section 114, states are prohibited from taxing retirement income of non-residents. New York cannot tax your pension or retirement account distributions once you are a Florida domiciliary, regardless of where the income was earned.
Non-New York business income — income from businesses that operate entirely outside New York — is not New York-source income. If you own a business with no New York operations, customers, or employees, that income follows your domicile.
For many high-net-worth individuals, these categories represent the majority of their income. The savings from moving are real and significant — they just do not cover everything.
Planning the Clean Break
The gap between a complete tax break and a partial one depends on the structure of your income. Two people with identical total income can have dramatically different outcomes.
Best case: An investor whose income is primarily dividends, capital gains, and interest, with no New York real estate and no New York business interests. This person’s New York tax obligation drops to effectively zero upon establishing Florida domicile. The savings are the full spread — potentially hundreds of thousands of dollars per year.
Worst case: A partner in a New York-based professional services firm who owns Manhattan real estate and has significant unvested equity from a prior New York employer. This person’s New York obligation drops, but a substantial portion of income remains New York-source for years. The savings are real but partial.
Most people fall somewhere between these extremes. The planning opportunity is in understanding exactly where you fall before the move, so the economics are clear and the timeline is honest.
Specific steps that accelerate the clean break:
- Sell New York real property before or promptly after the move. The gain is New York-source regardless of timing, but eliminating the ongoing rental income obligation simplifies your tax picture.
- Negotiate the remote work arrangement. If you work for a New York employer, ensure the structure withstands convenience-of-the-employer scrutiny. Documentation matters.
- Understand your entity allocations. Know what your K-1 New York allocation will look like for the first several years post-move. This is predictable and should be modeled in advance.
- Map your deferred compensation timeline. Identify every unvested grant, deferred comp plan, and future payout that will carry a New York allocation. Know the duration and magnitude.
- Time the move date for the part-year return. An earlier move date in the calendar year means fewer months of full-resident taxation. But it must be genuine — you must actually move on that date.
The Day Count Still Matters
Even after you have left, New York’s statutory residency rule can pull you back in.
If you maintain a permanent place of abode in New York — a home, apartment, or even a furnished room available for your use — and you spend more than 183 days in the state during a tax year, New York will tax you as a statutory resident on your worldwide income. Your Florida domicile does not protect you from this.
For people who keep New York property after moving, tracking days in New York is not optional. It is the single most important ongoing obligation of your tax residency change.
The statutory resident threshold is 183 days. You need to stay below it with certainty, not with estimates. A single miscounted day can mean the difference between a non-resident return with limited New York-source income and a full-resident return with tax on everything.
This is the problem Southbound was built to solve. The app passively tracks your location every day using background GPS on your iPhone. Your Departure Budget tells you in real time how many days you can spend outside Florida — or, viewed from the other direction, how many New York days you have left before you are at risk of statutory residency.
The data stays on your device. No servers, no accounts, no data sharing. When you need documentation for a tax filing or an audit, you export a clean CSV with every day accounted for.
The New York “exit tax” is not a one-time charge. It is an ongoing set of obligations that requires ongoing awareness. Know what you owe, know what you do not, and know where you are — day by day.
