What are the tax implications of taking out a business loan?

Loan Principal: Not Taxable Income

When your business receives loan proceeds, that money is not taxable income — it is debt that you are obligated to repay. The IRS treats loan principal as a liability on your balance sheet, not as revenue. This is true regardless of loan type: SBA loan, bank term loan, line of credit, equipment financing, or merchant cash advance. The funds enter your bank account tax-free, and you repay principal with after-tax cash flow.

Interest: Deductible as a Business Expense

Interest paid on a business loan is generally deductible as an ordinary and necessary business expense under IRC Section 162. The deduction applies to the interest portion of each payment only — not to principal repayments. Keep your year-end lender statements documenting total interest paid. For large businesses (average gross receipts above $32 million), the Section 163(j) limitation may cap deductible interest at 30% of adjusted taxable income — most small businesses are exempt from this cap.

Debt Forgiveness: Cancellation of Debt Income

When a lender forgives or cancels a portion of your business loan, the forgiven amount is generally taxable as 'cancellation of debt' (COD) income under IRC Section 61 and IRS Publication 525. This catches many borrowers off guard — if your lender settles a $200,000 balance for $120,000, the $80,000 difference is taxable ordinary income in the year of forgiveness. Exceptions apply in certain insolvency and bankruptcy situations under IRC Section 108.

PPP Loan Forgiveness: The Federal Exception

PPP loan forgiveness was explicitly exempted from federal taxable income by the Consolidated Appropriations Act (2021) — meaning forgiven PPP loan amounts do not generate COD income at the federal level. Additionally, the IRS clarified (via Rev. Rul. 2021-02 and Notice 2020-32) that expenses paid with forgiven PPP funds remain deductible. Most states conformed to this federal treatment, though a handful did not — check your state tax authority for conformity status.

SBA EIDL: Forgiveness is Rare but Taxable

EIDL loans are standard SBA loans with repayment obligations — they are not designed to be forgiven. EIDL Advance grants (up to $10,000 disbursed as a grant rather than a loan) were treated as non-taxable at the federal level. But if an EIDL loan is negotiated down or restructured with partial forgiveness in a workout, the forgiven amount is taxable COD income.

Merchant Cash Advances: Different Tax Treatment

A merchant cash advance (MCA) is not legally a loan — it is a purchase of future receivables. This distinction has significant tax implications. The fees paid on an MCA (the difference between the purchased amount and the advance amount — the 'factor rate' cost) are not classified as interest expense and are therefore NOT deductible under IRC Section 163. They are instead treated as a cost of financing or operating expense, deductible under IRC Section 162 as a business expense — but reported differently on your tax return and typically not captured on a Form 1098 or interest statement. Consult your CPA on proper classification.
