If we use a Section 453 installment sale to defer our capital gains taxes and the buyer defaults on their payments in year two, what happens to our tax liability on the unpaid balance, and how do we protect ourselves from paying tax on money we never receive?

A Section 453 installment sale is a powerful tool to defer taxes by spreading payments over multiple years. However, a major risk is buyer default. If the buyer defaults on their installment note in year two, you face a double disaster. You lose your cash flow, and you may still owe taxes on the deferred gain.

Under tax rules, if you sell your business and take an installment note, you recognize gain as you receive payments. If the buyer defaults and you foreclose on the business, the transaction is treated as a repossession. This repossession triggers a taxable event. You will have to calculate gain or loss based on the fair market value of the repossessed property compared to the basis of the unpaid note.

To protect yourself, you must structure the deal with robust security agreements. You should require a first priority lien on the business assets and a personal guarantee from the buyer.

Furthermore, your installment note must include a clawback provision. This provision must allow you to instantly step back into your seat on the Accountability Chart if a default occurs. By regaining operational control immediately, you can preserve the value of the enterprise. This will help you avoid tax liabilities on a dying asset and allow you to steer the company back to health.
