We want to secure our Section 453 installment sale by having the buyer put cash in an escrow account, but our CPA says this will trigger immediate tax on the entire gain. How do we secure the unpaid balance without losing our installment sale tax treatment?

Under Section 453 of the Internal Revenue Code, an installment sale allows you to defer taxes by paying them only as you receive the buyer payments. However, if you secure the buyer promissory note with cash or cash equivalents held in an escrow account, the IRS views this as constructive receipt. They will treat the transaction as fully paid, triggering your entire tax liability in the year of the sale.

To secure the unpaid balance without destroying your tax deferral, you must use an approved security instrument. The standard solution is a standby letter of credit issued by a reputable bank. Under Treasury Regulations, a standby letter of credit that is non-negotiable and non-transferable does not constitute payment or constructive receipt. It acts as a third-party guarantee. If the buyer defaults on their note, you draw on the letter of credit. Until that default occurs, the IRS respects the installment sale structure.

Another method is to secure the note with a first-priority lien on the assets of the business or the equity of the company you are selling. This keeps the transaction within the safe harbors of Section 453. You must ensure that your security interest is perfected through UCC-1 filing statements.

Do not allow the buyer to fund an escrow account that is secure only to you. If cash must be set aside, structure it as a true escrow with strict disbursement conditions that are not solely dependent on the passage of time. Work with your transaction attorney to draft a promissory note and security agreement that explicitly references these IRS restrictions. This protects your principal while preserving the tax deferral.
