What Is the Mortgage Interest Tax Deduction?

The mortgage interest deduction is an itemized federal income-tax deduction for qualifying interest paid on eligible home-secured debt.

A deduction generally reduces taxable income rather than directly reducing the amount of tax owed dollar for dollar. The actual tax effect depends on the taxpayer’s complete return.

The detailed federal rules are explained in IRS Publication 936. Homeowners should use the current-year publication and tax forms because federal tax law and filing requirements can change.

Tax Deduction vs. Tax Credit

These terms are not interchangeable.

Comparison	Tax Deduction	Tax Credit
General effect	Reduces taxable income when allowed.	Generally reduces tax owed, subject to the credit’s rules.
Mortgage interest	Usually considered an itemized deduction when eligible.	Mortgage interest is not generally treated as a standard federal tax credit.
Value	Depends on the taxpayer’s overall return and marginal tax situation.	Depends on whether the credit is refundable, nonrefundable or limited.

Itemizing vs. Taking the Standard Deduction

Mortgage interest generally matters federally only when itemized deductions are claimed.

Standard Deduction

A fixed deduction based primarily on filing status and other eligibility rules. Taxpayers do not separately claim mortgage interest when using only the standard deduction.

Itemized Deductions

Specific allowable expenses are listed on Schedule A. Home mortgage interest may be included when all applicable requirements and limitations are satisfied.

Taxpayers generally compare the allowable standard deduction with total allowable itemized deductions and use the option that produces the better federal tax result.

Who May Qualify?

Eligibility depends on the complete facts and records for the tax year.

Qualified Home

The debt generally must be secured by a main home or qualifying second home.

Legal Liability

The taxpayer generally must be legally responsible for the mortgage and have an ownership interest.

Interest Paid

The deduction generally relates to qualifying interest actually paid during the tax year.

Qualifying Loan Use

Debt commonly must be used to buy, build or substantially improve the residence securing it.

Itemized Return

Eligible interest is generally reported with itemized deductions on Schedule A.

Applicable Limits

The deduction may be limited when mortgage debt exceeds federal acquisition-debt limits.

Mortgage Debt Limits

Federal limits can depend on when the qualifying debt was incurred.

Debt incurred after December 15, 2017$750,000

General home-acquisition-debt limit, or $375,000 for married taxpayers filing separately.

Certain earlier qualifying debt$1,000,000

Higher legacy limit may apply, or $500,000 for married taxpayers filing separately.

Debt-limit calculations can be affected by multiple mortgages, refinancing, mixed-use loan proceeds, grandfathered debt and the average mortgage balance. Review current IRS Publication 936 or consult a tax professional.

Purchase and Refinance Mortgage Interest

The loan purpose and use of proceeds help determine tax treatment.

Purchase Mortgage

Interest on debt used to acquire a qualifying main or second home may be deductible, subject to the security, itemizing and debt-limit rules.

Refinance Mortgage

Refinanced acquisition debt may continue to qualify up to the outstanding principal balance of the old qualifying debt. Additional cash-out proceeds must be analyzed based on how they are used.

Home Equity Loans and HELOC Interest

Interest on a home-equity loan or home-equity line of credit is not automatically deductible merely because the debt is secured by a residence.

Under current federal guidance, the proceeds generally must be used to buy, build or substantially improve the home securing the debt. Interest on proceeds used for personal living expenses, such as paying credit-card debt, generally does not qualify as home acquisition interest.

Mortgage Points and Tax Treatment

Discount points are generally treated as prepaid interest, but timing rules vary.

Situation	General Federal Treatment
Qualifying principal-home purchase	Points may sometimes be deductible in the year paid when all IRS requirements are met.
Refinance	Points are commonly deducted ratably over the life of the new loan, subject to exceptions.
Second home	Points are generally deducted over the loan term rather than fully in the year paid.
Loan paid off early	Remaining unamortized points may receive different treatment depending on the payoff or refinance circumstances.
