We are structuring our transaction as an installment sale under Section 453 to defer our tax liability, but the buyer wants the right to offset any pre-closing indemnity claims against our unpaid promissory note principal. How do we structure these offset rights so we do not trigger immediate taxation on our deferred gain?

Using an installment sale under Section 453 is an excellent strategy to defer capital gains tax, but allowing unrestricted offset rights for indemnity claims can ruin your tax treatment. If the IRS determines that the principal amount of your promissory note is contingent or subject to recalculation based on post-closing events, they may classify the deal as a contingent payment sale. This can accelerate your tax liability or complicate your installment reporting.

To prevent this, you must structure the offset rights carefully. Rather than allowing the buyer to unilaterally reduce the principal of the note, require that any disputed indemnity claims be held in a separate, interest-bearing escrow account. The promissory note itself must remain a fixed obligation with a locked amortization schedule.

Furthermore, write a provision into the purchase agreement stating that any offset against the note is a last resort. The buyer must first exhaust other remedies, such as representation and warranty insurance, before touching the note.

To manage this risk operationally, run your due diligence prep like you run your quarterly EOS meetings. Use a dedicated Rock to review all potential liabilities and clean up any historical operational issues before signing. By presenting a clean, de-risked operation and structuring a rigid promissory note with structured escrow reserves, you protect your tax deferral and ensure your payments arrive as scheduled.
