I understand that you don't have to pay real estate,county,school tax if you are 100%PT veteran.Question I have is ,each state has a certain amount of money that you have to be under that sum to receive the tax credit.(example PA. is $88,800.00 for 2017,my question is say you apply and your under that amount for a few years and than one or two years you go over that amount.How much do to you have to pay back and how do they figure that amount you own back.I know every year the total amount goes up but curious about if you go over that amount what happens then.
