You paid hundreds, maybe thousands, in interest on a personal loan last year, and now you're wondering if any of it can shrink your tax bill. For most borrowers, the honest answer is no. But there are three real exceptions, and knowing them can save you money or keep you out of trouble with the IRS. Here's how the tax deduction on personal loan interest actually works as of July 2026.
Quick disclaimer up front: this article is general information, not tax advice. Talk to a CPA or tax professional about your specific situation before claiming any deduction.
The General Rule: Personal Loan Interest Is Not Deductible
The IRS treats interest on money borrowed for personal spending as "personal interest," and personal interest hasn't been deductible since the Tax Reform Act of 1986 phased it out. It doesn't matter how high the rate was or how necessary the expense felt.
That means no deduction for interest on loans used for:
- Weddings, vacations, or holiday spending
- Medical bills (the bills themselves may be deductible if you itemize, but the loan interest isn't)
- Consolidating credit card or other personal debt
- Emergencies, car repairs, or everyday expenses
What determines deductibility is not the loan type, it's what you spent the money on. That single idea drives all three exceptions below.
Exception 1: You Used the Loan for Business
If you spend personal loan proceeds on legitimate business expenses, the interest on that portion is generally deductible as a business expense. A freelancer who borrows $10,000 to buy equipment and cover software costs can typically deduct the interest on Schedule C. Rental property owners may deduct interest for property expenses on Schedule E.
Two rules matter here:
- Only the business portion counts. If you used 60% of the loan for business and 40% for personal spending, only 60% of the interest is deductible.
- Documentation is everything. Keep the loan agreement, statements showing interest paid, and receipts tying the money to business purchases. Separate accounts make this dramatically easier.
Exception 2: You Used the Loan to Buy Taxable Investments
Interest on money borrowed to purchase taxable investments, like stocks in a regular brokerage account, may qualify as investment interest expense. You claim it on Form 4952, and it comes with tight limits:
- You must itemize deductions to use it.
- The deduction is capped at your net investment income for the year, though unused amounts can carry forward.
- It doesn't apply to investments in tax-advantaged accounts like IRAs or 401(k)s, or to tax-exempt investments like municipal bonds.
Borrowing at typical personal loan rates to invest rarely makes financial sense, but if you did it, the deduction may soften the cost.
Exception 3: Some Education Uses (Read the Fine Print)
The student loan interest deduction lets eligible taxpayers deduct up to $2,500 of interest per year, and it's an above-the-line deduction, so you don't need to itemize. But a personal loan only qualifies if it meets the IRS definition of a "qualified education loan": borrowed solely to pay qualified higher education expenses, for an eligible student, at an eligible school, within a reasonable time of enrollment.
A general-purpose personal loan usually fails that test, especially if any portion went to non-education spending. Loans from relatives or employer plans never qualify. The deduction also phases out at higher incomes. If education borrowing is the goal, an actual student loan almost always beats a personal loan, both on rate and on tax treatment.
Related Tax Facts Borrowers Get Wrong
Loan proceeds are not income. The $15,000 that hit your bank account isn't taxable, because you have to pay it back.
Forgiven debt can be taxable. If a lender cancels part of your balance, say through a settlement, you may receive Form 1099-C, and the canceled amount is often taxable income. Exceptions exist for insolvency and bankruptcy.
Mixed use requires allocation. The IRS expects you to trace loan proceeds to their use. Guessing generously on the business percentage is a fast way to lose an audit.
If You're Shopping for a Personal Loan Anyway
Since the interest usually isn't deductible, the rate you pay matters even more. Comparing offers is the one lever every borrower controls.

Bottom Line
Interest on a personal loan is deductible only when the money funded business expenses, taxable investments, or, rarely, qualified education costs, and only with records to prove it. Everything else is nondeductible personal interest. Before you claim anything, run it past a tax professional. Before you borrow at all, compare rates so there's less interest to wish you could deduct.
Frequently Asked Questions
Can I deduct personal loan interest if I used the loan to pay off credit cards?
No. Consolidating personal debt is a personal use, so the interest isn't deductible. The consolidation can still be smart if it cuts your average rate, but it won't help at tax time.
Is personal loan interest deductible for a side hustle?
Generally yes, for the portion of the loan spent on the business. If you borrowed $5,000 and spent $3,000 on your side business, about 60% of the interest may be deductible on Schedule C. Keep receipts and statements that trace the money, and confirm the details with a tax professional.
Do I have to report a personal loan on my tax return?
No. Loan proceeds aren't income and monthly payments aren't deductible events. The exception is canceled debt: if your lender forgives part of the balance, you may get a 1099-C and owe tax on the forgiven amount.
Can I deduct the interest if I used a personal loan for tuition?
Only if the loan meets the IRS definition of a qualified education loan, meaning it was taken out solely for qualified education expenses and meets the other requirements. Mixed-use personal loans typically don't qualify. A dedicated student loan is usually the better tool for education costs.
