State tax filing
Yes, it can look like New York is taxing all your income, but that is not the case.
There is a screen in the New York Non-Resident Interview where you can indicate that the NY income belongs to your Spouse.
On the Review Topics screen, select your non-NY Wages, then Edit your W-2, and indicate 'do not allocate'. Repeat for any other income not allocated to NY.
If you're using TurboTax Desktop, you can also enter 0's manually on the Allocation Worksheet.
Your Form IT-203 should end up with only your spouse's income showing as NY AGI on Line 31. Then on Line 45, a factor is applied to NY AGI/Total AGI to calculate the NY tax.
