Field Guide to Mortgage Interest Deduction

(Updated July 2012)

Introduced along with the Income Tax in 1913, the Mortgage Interest Deduction (MID) allows homeowners who itemize their taxes to deduct mortgage interest attributable to primary residence and second-home debt totaling $1 million, and interest paid on home equity debt up to $100,000. Though the MID is a popular tax deduction for millions of U.S. homeowners, it has become a controversial topic in recent years. This field guide highlights basics, perceived pros and cons, IRS rules, and more to get you up-to-speed on this widely-debated tax deduction.
