If your business has loans but your Profit & Loss shows little or no interest expense, something in your books is off. Every commercial loan charges interest — it's the cost of borrowing. If that cost isn't showing up, loan payments are being recorded in a way that doesn't capture the full picture.
This is more common than you'd think, and it affects both your financial statements and your taxes.
Interest is a real business expense, just like rent or payroll. It belongs on your Profit & Loss as Interest Expense and reduces your net income accordingly. It's also generally tax-deductible for business loans — if it's not being recorded, you're likely missing a deduction.
At the same time, loan principal repayments are not expenses — they reduce the loan balance on your Balance Sheet. These two components of every loan payment need to be recorded separately. When they aren't, one or both parts get lost or misrepresented.
The entire payment is applied to the loan liability only. If the loan is set up correctly as a liability account but every payment is recorded as a simple reduction of that balance — with no split for interest — the loan balance decreases correctly but no interest expense is ever captured on the Profit & Loss.
The entire payment is recorded as a single expense. Some business owners record the full loan payment to a generic expense account like "Loan Payment." This creates some expense, but it lumps principal and interest together — and the loan liability on the Balance Sheet never decreases. (This is related to the issue covered in our article on recording loan payments as expenses.)
The loan wasn't set up as a liability to begin with. If the original loan proceeds were recorded as income rather than a liability, the payment history likely has no consistent structure for splitting principal and interest correctly.
The interest genuinely is zero — but that's rare. Owner loans, family loans, or certain EIDL loans may carry a 0% rate. In those cases, zero interest expense is correct. But for any commercial loan — SBA, bank, equipment financing, line of credit — there should always be interest showing.
Look at your Profit & Loss. Go to Reports → Profit & Loss. Search for an Interest Expense line. If it's absent — or the amount is far lower than what your loan statements show you're paying in interest — the payments aren't being split correctly.
Compare against your loan statements. Pull the most recent statement from each lender. Every statement shows the total payment, the principal portion, and the interest portion. Compare the interest amounts to what's in QBO. The gap between the two is the amount being missed each period.
Check the loan account register. Go to Accounting → Chart of Accounts, find the loan liability account, and open the register. If every payment shows the full amount reducing the principal balance — with no separate interest entries — you're not recording interest at all.
Fixing this involves restructuring how loan payments are recorded so that each payment is split between the principal (which reduces the loan balance) and interest (which hits the Profit & Loss as an expense). Your loan's amortization schedule — available from your lender — provides the exact principal/interest breakdown for every payment.
For prior periods where interest wasn't recorded, there's a catch-up process. How far back you go, and whether you work through current-year Profit & Loss or directly through prior-year equity, depends on materiality and what years have already been filed — something to review with your accountant before making changes.
The Fix Guide covers the split-payment setup and the catch-up approach step by step.
If you have a loan from yourself, a family member, or a zero-interest financing arrangement, no interest expense is expected. Make sure the loan terms are documented and that QBO reflects the correct setup. Owner loans without documented interest may also have imputed interest implications worth discussing with your CPA.
