My mortgage has an escrow account for paying property taxes. I expect form 1098 for tax year 2017 will report only property taxes paid through that escrow account.
However, due to the changes in tax law, which appear to allow prepayment of 2018 property taxes that were already assessed, I went ahead and prepaid two quarters worth of property taxes. I have a stamped receipt from the town tax office.
I plan to itemize deductions for tax year 2017. But my property taxes paid will include both the escrow payments and my prepayment, and that's what I will report for deduction. However, the 1098 amount will be different.
Is that likely to trigger an audit? If so, is there a way to attach the stamped receipt to document that I prepaid, so that the IRS can see my numbers are correct?
