Definition
Interest deductions allow taxpayers to subtract certain interest expenses from their gross income, effectively reducing their taxable income. The treatment of interest deductions varies based on the type of interest and the associated expense.
Examples
Investment Interest:
An investor who borrows money to purchase stocks and bonds can deduct the interest paid on these loans, up to the amount of net investment income earned from the investments. For instance, if an investor earns $5,000 in net investment income and pays $6,000 in investment interest, only $5,000 of the interest is deductible.
Construction Interest:
A real estate developer incurs $50,000 in interest expenses during the construction of an office building. This interest must be capitalized and added to the building’s cost basis, to be depreciated over its useful life, beginning when the building is ready for use.
Business Interest:
A small business owner takes out a loan to finance business operations, incurring $10,000 in interest expense. Because the owner plays an active role in the business, the full $10,000 is deductible.
Housing Interest:
A homeowner with a mortgage balance of $800,000 and an additional home equity loan of $50,000 can deduct the interest on both loans. However, the combined debt must not exceed $1 million for acquisition debt and $100,000 for home equity debt to be fully deductible.
Consumer Interest:
Interest paid on personal expenses such as credit card debt or auto loans does not qualify for tax deductions. Therefore, if a person pays $2,000 in interest on their credit card debt, it is not deductible.
