We are structuring an installment sale under Section 453 to spread our tax hit, but we are terrified the buyer will run the company into the ground before we get fully paid. How do we structure acceleration clauses and security interests without ruining our tax deferral status?

Carrying an installment note under Section 453 is an excellent way to defer your capital gains tax, but it turns you into a junior lender without a lender's traditional protections. If the buyer mismanages the business, you could lose both your remaining payments and your equity. To mitigate this risk without triggering immediate tax liability, you must draft a robust promissory note secured by the assets of the business or a pledge of the outstanding stock. The key is to include strict operational and financial covenants that trigger an automatic acceleration of the debt if breached. These covenants should include maintaining a minimum debt-service coverage ratio, keeping a defined level of working capital in the business, and prohibiting any owner distributions or management fees to the buyer's sponsors if covenants are violated. You can use your V/TO and the weekly Scorecard to monitor these metrics. If the buyer fails to hit these agreed operational baselines for two consecutive quarters, the note should automatically accelerate, making the entire balance due immediately or allowing you to foreclose on the stock and retake control of the company. The Internal Revenue Service allows these protective default provisions because they do not represent contingent payments or guaranteed additional proceeds; they are merely security mechanisms. This structure keeps your tax deferral intact while giving you the teeth to protect your cash.
