Claiming Home Mortgage Interest You must itemize your deductions on Form 1040, Schedule A to claim mortgage interest. This means foregoing the standard deduction for your filing statusâit's an either/or situation. You can itemize or you can or you can claim the standard deduction but you can't do both.
The IRS has a 10 year period of time in which to collect back taxes. After that ten year period of time, the back taxes drop off the tax data base and the debt is legally forgiven and can never be collected. The federal tax liens are also released by statute.
First, in order to collect a refund, a tax return must be filed with the IRS no later than three years from the due date of the return. After that, the money gets absorbed by the treasury, so you should stay on top of it. There is no penalty for filing a late return if you qualify for a refund.
