Acquisition indebtedness is a key tax concept that defines the type of mortgage debt eligible for interest deductions on federal income taxes. Specifically, it covers loans taken out to purchase, build, or significantly improve your primary or secondary residence. This term is essential for taxpayers looking to reduce their taxable income through the mortgage interest deduction.
Background and Historical Context
The mortgage interest deduction has been part of U.S. tax law for decades, designed to encourage homeownership by making it more affordable. Originally, there were few limits on the amount of mortgage interest homeowners could deduct. However, to maintain tax system fairness and government revenue, Congress introduced restrictions on acquisition indebtedness.
The Tax Cuts and Jobs Act (TCJA) of 2017 notably changed the rules by capping the deductible mortgage debt at $750,000 for loans taken out after December 15, 2017. Loans originating before this date may still qualify for deductions up to $1 million due to grandfathering provisions.
How Acquisition Indebtedness Works
Acquisition indebtedness applies when you use a loan secured by your home to buy, build, or substantially improve it. The IRS permits you to deduct the interest paid on this loan up to the specified limits.
Key points include:
- Loan Purpose: The debt must be used for acquisition (purchase or construction) or significant improvements that add value or extend the home’s life.
- Primary and Secondary Homes: Acquisition indebtedness applies to both your main residence and one secondary home.
- Loan Limits: For mortgages originated after December 15, 2017, the limit is $750,000 ($375,000 if married filing separately). For older loans, the limit is $1 million ($500,000 if married filing separately).
- Refinancing: Refinanced loans retain the acquisition indebtedness status up to the original loan balance used for acquisition or improvement.
Distinguishing Acquisition Indebtedness from Other Debts
Not all home-related debt qualifies. Loans such as home equity loans or HELOCs used for personal expenses (vacations, credit card payment) do not qualify as acquisition indebtedness and thus their interest is generally not deductible.
Practical Examples
-
Home Purchase: You purchase a home with a $400,000 mortgage. This entire amount is acquisition indebtedness, allowing you to deduct the interest paid on the full loan (subject to limits).
-
Home Improvement: You have a $350,000 mortgage and take a $50,000 home equity loan to renovate your kitchen. Since the equity loan is used to improve the home, the combined $400,000 debt can qualify as acquisition indebtedness.
-
Refinancing: If you had a $900,000 mortgage before the TCJA and refinance it for $850,000, the acquisition indebtedness limit remains $1 million because of grandfathering rules. Your interest deduction applies to the $850,000 loan balance.
Who is Eligible?
Homeowners who itemize deductions and hold mortgages secured by their primary or one secondary home can benefit from acquisition indebtedness rules. They must ensure their loans meet the acquisition purpose criteria and remain within IRS limits.
Tips for Homeowners
- Keep detailed documentation distinguishing acquisition debt from other loans.
- If refinancing, verify how much of your new loan balance retains acquisition indebtedness status.
- Use home equity loans for substantial home improvements to potentially preserve interest deductibility.
- Consult with a tax advisor annually due to evolving tax laws.
Common Misunderstandings
- Not all mortgage interest is deductible—only interest on acquisition indebtedness within limits.
- Loans used for personal expenses like vacations don’t qualify for mortgage interest deduction.
- Credit card balances or personal loans, even if for home costs, do not qualify unless secured by the home and used for acquisition or improvement.
