Business loans involve two types of entries in your books. The loan itself is a liability that shows up on your balance sheet. The interest portion of each payment is an expense that reduces your taxable income. Getting this right matters for accurate financial statements and for claiming interest deductions at tax time.

When you receive loan funds, record the full amount as an increase to your bank account and an increase to a long-term liability account. Name the account something specific like “SBA Loan - First National Bank” so you can track it easily. This isn’t income. It’s borrowed money you have to pay back.

Each monthly payment gets split two ways. Part goes toward principal, which reduces your loan balance. Part goes toward interest, which is a business expense. You can’t just record the full payment as an expense because that overstates your deductions and understates your debt. A Metro Detroit bookkeeping service can set this up correctly from the start so you don’t have to figure out the entries yourself.

Your lender should provide an amortization schedule showing exactly how each payment breaks down. Keep this handy. In QuickBooks, record each payment as two separate lines. One reduces the loan liability account for the principal portion. The other hits an interest expense account for the interest portion. The total of both lines equals your actual payment amount.

If you don’t have an amortization schedule, ask your lender for one. For lines of credit where the balance fluctuates, the interest calculation changes monthly based on what you owe. Check your statement each month to see the interest charged.

Common mistakes include recording loan proceeds as income, which creates a false tax liability. Others expense the entire payment, which overstates deductions. Some never reconcile the loan balance at all. At least quarterly, compare the balance in your books to the balance your lender shows. They should match.

Interest expense is fully deductible for most business loans. This includes SBA loans, equipment financing, lines of credit, and vehicle loans when the vehicle is used for business. Keeping clean records of interest paid makes tax preparation straightforward. Full-service bookkeeping handles this tracking automatically so your loan balances and interest expenses are always accurate.
