@LayneNP Did you find any documentation to substantiate that?
Page 20 of the IT-203 instructions says:
If you earned your salary or wages both inside and outside of New York State, you must determine the amount that is allocable to New York State. This is not necessarily the amount shown in the State wages, tips, etc. box on your Form(s) W-2. ... To allocate income that does not depend directly on the volume of business transacted (for example, wages), complete Schedule A, Allocation of wage and salary income to New York State, on Form IT-203-B to determine the amount earned in New York State.
then going over the IT-203-B instructions, it goes right into days calculation... which, as you said, is pretty tedious and unneeded.
I've moved to a New York office mid-year and for me, allocation would preferably be a simple matter of including only wages received in New York. However, the phrasing of the instructions make it seem like NY intentionally wants to use an allocation method of their choice that might be favorable to them even if it doesn't accurately allocate the income.
Is there something I'm missing in my reading of the instruction? Is using the IT-203-B "sheet" optional?
