Quick Answer
Personal loan interest is generally not tax deductible. Unlike mortgage or student loan interest, the IRS doesn't allow deductions for interest on personal loans used for personal expenses. However, if you use personal loan funds for qualifying purposes like business expenses, home improvements, or investments, portions may be deductible.

Can I deduct interest on a personal loan?
Personal loan interest is not tax deductible when used for personal expenses. The IRS eliminated the deduction for personal interest in 1986, which means interest on personal loans, credit cards, auto loans, and other consumer debt cannot be deducted on your tax return.
What qualifies as non-deductible personal interest
Never deductible:
Example: Typical personal loan scenario
Mark takes a $25,000 personal loan at 8.99% APR to consolidate credit card debt. His annual interest payments are approximately $2,247 in the first year.
Tax impact: $0 deduction. Even though Mark pays substantial interest, none of it reduces his taxable income because it's personal consumer interest.
If it were deductible: At a 22% tax bracket, Mark would save about $494 in federal taxes ($2,247 × 22%). But since it's not deductible, he receives no tax benefit.
Comparison with deductible interest types
The "use of funds" rule
The key tax principle is how you use the loan proceeds, not the loan type. Even a "personal" loan can have deductible interest if used for qualifying purposes.
Example: Sarah gets a $15,000 personal loan but uses $10,000 to install solar panels (home improvement) and $5,000 for a vacation.
What you should do
If you have personal loan interest:
1. Don't claim it as a deduction for personal expenses
2. Track the use of funds if any portion went to deductible purposes
3. Consider refinancing with a home equity loan if you're a homeowner (interest may be deductible)
4. Use our [return-scanner](return-scanner) to find legitimate deductions you might have missed
Key takeaway: Personal loan interest is not deductible for personal expenses. Only the purpose of the loan funds, not the loan type, determines deductibility.
Key Takeaway: Personal loan interest is not tax deductible when used for personal expenses, regardless of the interest rate or loan amount paid.

Home improvement exception for homeowners
If you're a homeowner who used personal loan proceeds for qualifying home improvements, you might be able to deduct the interest under home equity interest rules, even if it's technically a "personal" loan.
When personal loan interest may be deductible for homeowners
Requirements:
Qualifying home improvements:
Not qualifying:
Example: Home improvement personal loan
Lisa takes a $30,000 personal loan at 9.5% to renovate her kitchen. Her annual interest is $2,850. She itemizes deductions and her total mortgage debt is $400,000.
Potential deduction: $2,850 in mortgage interest (reported on Schedule A)
Tax savings: At 24% bracket, approximately $684 in federal tax savings
Documentation needed:
Consider home equity alternatives
If you haven't taken the loan yet:
Mixed-use allocation
If you used loan proceeds for both qualifying and non-qualifying purposes, you must allocate interest:
Example: $20,000 loan - $15,000 for kitchen, $5,000 for vacation
Keep meticulous records to support any home improvement interest deduction claims.
Key Takeaway: Homeowners may deduct personal loan interest if proceeds were used for qualifying home improvements, subject to the $750,000 debt limit and itemization requirement.
