Personal loans do not affect your tax return in most cases. The only reason personal loans typically affect tax returns is if the borrower qualifies for a tax deduction of the interest they pay. There are a few reasons why personal loan interest might be tax deductible, and three of the most common are when the personal loan was used to fund higher education expenses, to fund a business, or to buy investments. But it’s important to know that personal loan proceeds aren’t considered income, and do not need to be reported on your tax return.
