How To Write Off Small Business Loan Interest

Whether you’re a small business filing as a sole proprietor, an s-corporation or a partnership, you can write off business loan interest on your annual federal income tax return. You can use Form 8990 to determine how much interest can be deducted and how much you can carry over to another tax year.

Form 8890 requires a calculation of the interest expense, which provides you with the amount you can write off now and in the future. The calculation may include the interest you paid during the filing year and the portion of interest expense disallowed from a prior year that’s now eligible for a deduction. Although the IRS allows businesses to carry forward the excess interest paid to next year’s return, you’ll need to save your receipts to show how the loan’s proceeds were spent.
