State tax filing

Since Florida doesn't have a state income tax, there won't be a line on the W-2 showing Florida income. However, NY requires employers to report all of your income on the NY line on the W-2 because of the way tax is calculated.

The way NY taxes part year residents is a little different than many of the other states. New York calculates tax based on your full year income. Then there's an income percentage that's applied to that tax liability. That income percentage prorates your tax liability based on how much income you actually earned in New York.

When you get to the New York Income Allocation screen, you will need to choose No and then on the next few screens you'll indicate how much of your income you earned while a NY resident. This will calculate your income percentage that's applied to your tax liability based on your full income.
