We are using a Section 453 installment sale to spread our tax hit over five years, but the buyer wants the right to assign our installment note to a new holding company they are forming for their next acquisition. How do we prevent this assignment from triggering our full tax liability or exposing us to unrated debt?

Under Internal Revenue Code Section 453, an installment sale allows you to defer capital gains taxes, but the rules regarding the disposition of installment obligations are strict. If a transfer is structured incorrectly, or if the note is deemed constructively paid, it can accelerate your entire deferred tax liability immediately.

To protect yourself, your installment note must include a strict anti-assignment clause. This clause must state that the buyer cannot transfer, sell, or assign the note to any parent, subsidiary, or third-party entity without your prior written consent. If they are forming a new holding company, that entity must not be allowed to assume the debt unless the original operating company and its principal owners remain fully liable as primary co-obligors or guarantors.

Additionally, you must evaluate the creditworthiness of any proposed assignee. If a buyer transfers your note to a highly leveraged holding company with no operating assets, your credit risk increases.

Insist on a covenant requiring the note to be backed by a standby letter of credit or collateralized by specific, high-quality operating assets. This ensures that even if the buyer restructures their corporate entities, your tax-deferred status remains secure and your principal is fully protected against a post-close corporate shell game.
