Frequently asked questions

Can any homeowner claim this credit?

No. You must have been issued a qualified MCC by a state or local governmental unit or agency under a qualified program.

How long can unused MCC credit carry forward?

A credit limited by tax liability can generally carry to the next 3 tax years or until used, whichever comes first.

Can I also deduct the same mortgage interest?

You must reduce the Schedule A home mortgage interest deduction by the current-year credit computed on Form 8396 line 3.
