Sorry, if you live in Pa. full time and work in DE fulltime, the tax situation works as follows: Example - DE will tax your pay
They have 6 tax brackets based on your taxable income, ranging from 2.2 % to 6.6%. Since PA is a flat 3.07 %, you will pay more tax in DE once your bracket is above 3.7%. You will Not be reimbursed by PA for any amount paid in DE that is above what you Would have paid in PA. You will get a credit using the PA tax form for the taxes you paid DE up to the 3.7 %.
Working in DE can be expensive as your salary gets to the 6.6 rate while PA will only credit up to 3.7%. You eat the rest.
