CALCULATE THE CREDIT
Total Mortgage Amount X Loan Interest rate = Annual interest
Annual Interest X MCC Mortgage Credit Certificate Rate (20%) = Tax Credit for the year
Assuming a mortgage of $100,000 at 5.5% interest, the annual tax credit would be:
$100,000 X 5.5% = $5,500
$5,500 X 20% = $1,100 annual tax credit.
The specific amount of the mortgage interest credit depends on home much interest you pay on the mortgage loan, however, the amount of the credit can not be more that your annual federal income tax liability after all other credits and deductions have been taken into account. The unused portion of the mortgage interest credit can be carried forward to the next years, or until used, whichever comes first. Refer to IRS Form 8396 to calculate and claim your credit.
