If you literally move your domicile (your main, primary home) from FL to NY in 2024, then for tax year 2024 you will be considered a part-year resident of both states. You will become a part-year resident of NY on the day you begin living in New York with the intent (as evidenced by your actions) of it being your new domicile. If you receive the bonus after that date, it will be taxable by New York. If you receive the bonus before that date, it will not be taxable by New York.
If you keep your domicile in Florida, and your time in New York is temporary in nature, then your bonus would be taxable by New York only if you fall under the 184-day rule, which is stated here:
You may be subject to tax as a resident even if your domicile is not New York.
You are a New York State resident if your domicile is New York State OR:
- you maintain a permanent place of abode in New York State for substantially all of the taxable year; and
- you spend 184 days or more in New York State during the taxable year. Any part of a day is a day for this purpose, and you do not need to be present at the permanent place of abode for the day to count as a day in New York.
- In general, a permanent place of abode is a building or structure where a person can live that you permanently maintain and is suitable for year-round use. It does not matter whether you own it or not.
