for example, say i only have income on w2, which is 100K for taxable income.
what you mean is that on my w2, PA state wage and NY state wage should both be 100k?
when i use turbotax to file my tax, although on my w2, PA state wage is 0, turbotax did include NY state wage as my income for PA filing and used NY tax to offset my PA tax.
but i am not sure if that is the case for local tax, as you said, if there is box 18 on w2, i should use that for local tax, but i called the local tax office, they said i should use state wage in box16, 'cus that is what the audition will use. there is no use of box 18, i checked the link you give for Bethel Park, and there is no place i can input the number in box 18
