<prompt> Human: My dad has an accountant so I gave him my W2 this year. He says I owe 600 to New York State because I worked for 3 months in Florida before moving up here and their law states that I have to pay NY state taxes on that income. Does anyone know if this is true?  <response>: Look at the forms yourself. Check his math. Then you will know for yourself. But since I just moved to New York State, I will hazard a guess that it is correct. You do your taxes as if all money was made in New York State, determine the tax owed per New York State rules, then use a ratio based on your total income earned. It is counter intuitive.
