Definition

The mortgage interest deduction is a tax benefit that allows homeowners to deduct the interest paid on loans used to build, purchase, or improve a residence from their taxable income. This deduction can also apply to loans for a second home and vacation homes, but with certain limitations.

Origin

The origin of the mortgage interest deduction dates back to the early 20th century when the U.S. government introduced this policy to encourage homeownership. The aim was to stimulate the housing market by reducing the tax burden on homebuyers.

Categories and Features

The mortgage interest deduction is primarily divided into two categories: loans for a primary residence and loans for a second home or vacation home. Interest on loans for a primary residence is typically fully deductible, whereas interest on loans for a second home may be subject to deduction limits. The main feature of this policy is to reduce the taxpayer's taxable income, thereby lowering their tax liability and encouraging homeownership.

Case Studies

Case Study 1: In the United States, a homeowner purchased a $500,000 house in 2023, financing $400,000 through a loan. The homeowner paid $15,000 in loan interest in 2024, which can be deducted from their taxable income, reducing their tax burden. Case Study 2: Another homeowner owns both a primary residence and a vacation home. For the vacation home's loan interest, the homeowner can only deduct within certain limits, depending on the total loan amount and other tax regulations.

Common Issues

Common issues include: What types of loan interest can be deducted? Generally, only interest on loans used to purchase, build, or improve a residence can be deducted. Another common question is how to determine the deductible interest amount. Loan companies typically report the deductible interest amount on Form 1098 each year.
