We didn’t allow the amount claimed as mortgage interest credit on page 2 of your tax return because mortgage interest paid shown on Form 1098 must be reported on line 10 of Schedule A, Itemized Deductions. Note: If you have other itemized deductions in addition to mortgage interest, or your mortgage interest is more than the standard deduction, you may file Form 1040X, Amended U.S. Individual Income Tax Return, and include them on Schedule A, Itemized Deductions, to reduce your tax.
