answer:Nobody here can guess the amount of your payments, how often you make them, or whether your outstanding liability has been accruing interest over the years. We don’t even know whether you’re asking about federal income tax, state income tax, local real estate tax, etc. I urge you to find a telephone number for the appropriate taxing agency and call for an answer. After you’ve reached the right party, you should get the information quickly. Please let us know what happens.
