Mortgage Interest Deduction

Definition

The Mortgage Interest Deduction (MID) is a provision in the U.S. tax code that allows homeowners to subtract the interest paid on their mortgage from their taxable income. This can result in a significant tax saving and is intended to encourage homeownership by reducing the overall cost of owning a home.

Examples

Example 1: Single-Family Home Jane owns a single-family home with a mortgage of $300,000. Over the year, she pays $15,000 in mortgage interest. She can deduct this $15,000 from her taxable income, which reduces her taxes owed.
Example 2: Primary Residence and Vacation Home John owns a primary residence and a vacation home. He pays $10,000 in interest on his primary home’s mortgage and $5,000 on the vacation home’s mortgage. He can deduct a total of $15,000 of mortgage interest from his taxable income.
