Are SBA Loan Payments Tax Deductible? Interest, Principal, and Fees

Are SBA loan payments tax deductible? Partly. The interest portion of each payment is deductible as an ordinary business expense, and so are loan fees (spread over the life of the loan), but the principal portion is not deductible because repaying borrowed money isn’t a business expense in the tax code’s eyes.

Why the Principal Portion Doesn’t Count

When your SBA loan funds arrive, the IRS doesn’t treat them as taxable income. You owe the money back, so it isn’t yours in a tax sense. The mirror image of that rule is what trips up most borrowers: paying the principal back isn’t a deductible expense either. You’re returning capital, not spending it on the operation of your business.

Every monthly payment you make is split between principal and interest. Only the interest side qualifies. Your lender’s amortization schedule or year-end statement shows the split, and you need that breakdown to file correctly.

What Interest You Can Deduct

Federal tax law allows a deduction for all interest paid or accrued on business debt during the tax year.1Office of the Law Revision Counsel. 26 USC 163 – Interest That covers the full range of SBA lending products: 7(a) loans, 504 Certified Development Company loans, microloans, and Economic Injury Disaster Loans. What you bought with the money doesn’t change the rule. Working capital, equipment, or real estate — the interest is deductible either way.

You deduct interest actually paid, or accrued if you use accrual accounting, during the year. The deduction reduces your business’s taxable income dollar for dollar.

Conditions You Have To Meet

Not every dollar of interest qualifies automatically. A few conditions apply:

  • The loan proceeds must go to legitimate business purposes. Any portion diverted to personal spending produces non-deductible personal interest on that slice.
  • You must be legally obligated to repay the debt. Your name, or your business entity’s name, has to appear on the promissory note.
  • A real debtor-creditor relationship must exist, backed by a written agreement to repay a fixed amount.

How Interest Tracing Works

When you use loan proceeds for more than one purpose, IRS “interest tracing” rules decide which portion of the interest is deductible. Interest follows how you actually spent the money, not what secures the loan.2eCFR. 26 CFR 1.163-8T – Allocation of Interest Expense Among Expenditures Pledge personal stock as collateral for a business loan, and the interest is still business interest because the proceeds went to the business.

The reverse also holds. Deposit SBA loan proceeds into a general account, then pull some out for personal expenses, and the interest tied to those personal withdrawals stops being deductible on your business return. An optional 15-day rule lets you treat any expenditure made from an account within 15 days of depositing borrowed funds as coming from those borrowed funds, which can simplify the math.2eCFR. 26 CFR 1.163-8T – Allocation of Interest Expense Among Expenditures The cleanest fix is to keep SBA loan proceeds in their own bank account.

The Section 163(j) Cap on Business Interest

Even after interest qualifies as a business expense, a second rule can limit how much you deduct in a given year. Under Section 163(j), non-exempt businesses may deduct business interest only up to the sum of their business interest income plus 30 percent of adjusted taxable income for the year.3Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense Interest above the cap carries forward to later years.

Most small businesses are exempt. If your average annual gross receipts over the prior three tax years fall below the inflation-adjusted threshold ($31 million for 2025, with the 2026 figure expected to be similar) and you are not a tax shelter, the cap doesn’t apply.4Internal Revenue Service. Instructions for Form 8990 Larger businesses file Form 8990 to work out the allowable deduction.

Loan Fees, Guarantee Fees, and Closing Costs

Upfront costs of getting the loan — guarantee fees, origination fees, closing costs, appraisal fees — don’t work like interest. You cannot write them off in the year you pay them. They must be capitalized and deducted gradually over the life of the loan through amortization.5Internal Revenue Service. Publication 551, Basis of Assets

A $5,000 guarantee fee on a ten-year SBA loan produces a $500 deduction each year for ten years. SBA 7(a) guarantee fees vary by loan amount and maturity, and some smaller loans to manufacturers or veteran-owned businesses may carry reduced or waived fees. The amortization method is the same regardless. Keep a schedule that tracks the original fee, the annual deduction, and the remaining unamortized balance.

If You Refinance or Pay Off Early

Ending an SBA loan ahead of schedule has two tax consequences worth knowing.

Prepayment penalties charged by the lender are generally treated as additional interest, so they’re deductible as interest in the year you pay them. SBA 504 loans carry a declining prepayment penalty during the first ten years, and 7(a) loans with maturities of 15 years or more may have a prepayment charge during the first three years.

If you’ve been amortizing loan fees over the original term and pay the loan off early, you may be able to deduct the entire remaining unamortized balance in the year of payoff. When a loan is fully retired rather than refinanced into a new loan with the same lender, unamortized costs can generally be written off at that point.6Internal Revenue Service. Deductibility of Unamortized Debt Issuance Costs If the loan is refinanced through a significant modification into a new debt instrument, treatment depends on how the new loan’s issue price is determined, and in some cases the unamortized costs must be spread over the new loan’s term instead.

Depreciating What You Bought With the Loan

The principal side of the payment isn’t lost tax-wise if you used the loan to buy something depreciable. If loan proceeds paid for equipment, vehicles, or other tangible business property, the cost of that property can be recovered over time (or all at once).

  • Section 179 deduction: for the 2026 tax year, you can elect to deduct up to $2,560,000 of qualifying equipment or property in the year you place it in service. The benefit phases out once total qualifying purchases exceed $4,090,000 for the year.
  • Bonus depreciation: under recently enacted legislation, 100 percent first-year bonus depreciation is available for qualifying property placed in service in 2026.
  • Standard depreciation: for assets that don’t qualify for those methods, or when you don’t elect them, you depreciate the cost over the asset’s useful life as defined by the IRS (typically five to seven years for equipment, or 39 years for commercial real estate).

Your deduction comes from the asset itself. Whether you paid cash or borrowed the money doesn’t change your depreciation options.

If Part of the Loan Is Forgiven

Debt cancellation flips the tax picture. If any portion of your SBA loan is forgiven, cancelled, or settled for less than the full balance owed, the forgiven amount is generally taxable income in the year of cancellation.7Internal Revenue Service. Topic No. 431, Canceled Debt – Is It Taxable or Not? That can hit hard when a business negotiated a settlement precisely because it was already in trouble.

Several exclusions can reduce or eliminate the tax:

  • Bankruptcy: debt discharged in a Title 11 case is excluded from gross income.8Office of the Law Revision Counsel. 26 U.S. Code 108 – Income From Discharge of Indebtedness
  • Insolvency: if total liabilities exceeded the fair market value of your assets immediately before the discharge, the cancelled amount can be excluded up to the extent of your insolvency.8Office of the Law Revision Counsel. 26 U.S. Code 108 – Income From Discharge of Indebtedness
  • Qualified real property business debt: for taxpayers other than C corporations, cancellation of debt secured by business real property may qualify for exclusion.
  • Qualified farm indebtedness: farmers meeting specific criteria can exclude cancelled debt from income.

Using an exclusion generally requires you to reduce certain tax attributes — net operating loss carryforwards, the basis of your property — by the excluded amount. You report the exclusion and the attribute reduction on IRS Form 982.

Where To Report the Deduction

If your lender received at least $600 in interest from you during the year, they are required to send you Form 1098 showing the total.9Internal Revenue Service. Form 1098 Mortgage Interest Statement Not every commercial lender issues one for business loans, so if you don’t receive it, use the year-end statement or amortization schedule to pull the correct figure.

Where the deduction lands depends on your entity type:

  • Sole proprietorships report interest on Schedule C of Form 1040.9Internal Revenue Service. Form 1098 Mortgage Interest Statement
  • Partnerships report on Form 1065.
  • S corporations report on Form 1120-S.
  • C corporations report on Form 1120.

Hold onto the original loan agreement, the amortization schedule, payment receipts, and any year-end interest statements. If you’re amortizing loan fees, keep a separate running schedule that shows the original fee, the annual deduction, and the balance still to be amortized. Those records back up the deduction if the IRS asks, and they make sure you don’t leave money on the table each year.
