For the local earned income tax, the rate varies with location, from zero up to 3%. Withholding is listed in box 19 of your W2. This tax only applies to W2 income and self-employment profits (use same number that is on your PA Schedule C and include a copy). The return is all of one page, about 10 minutes to fill out once you've located your W2s for each year and copy of your PA tax return that you printed out and stored in a safe place.
