Is interest on a personal loan tax-deductible?
No, in most cases. Interest on personal loans used for personal expenses (debt consolidation, weddings, vacations, medical, home improvement on someone else's home) is not deductible. Interest on personal loans used exclusively for business expenses or for investment in income-producing assets may be partially deductible. Consult a tax professional.
Context
The IRS treats personal-loan interest based on what the funds are used for, not what kind of loan it is. Most personal uses (the bulk of personal-loan borrowing) generate non-deductible interest.
Narrow exceptions where interest may be deductible: business expenses (Schedule C), investment in income-producing assets (Schedule A investment interest, with limitations), or qualified educational expenses (in some cases, on Form 1098-E for student-loan interest, which is a specific federal-loan category).
Mortgage interest, HELOC interest used to substantially improve the home that secures the loan, and home-equity-loan interest under similar conditions can be deductible if you itemise. These rules are why HELOCs are often financially better than personal loans for home improvement despite the slower closing.
