Can you combine a Section 1031 exchange with a Section 453 installment sale?

Question

Tyler Smith · Accepted Answer

Yes, real estate investors frequently combine an IRC Section 1031 like-kind exchange with a Section 453 installment sale. This combined approach is governed by Section 453(f)(6) and Treasury Regulation Section 1.453-1(f), often referred to as an installment sale boot coordination.

How the Dual Strategy Works

When a seller transfers real property worth more than the replacement property they acquire, they face taxable boot. Instead of receiving that boot in cash, which triggers immediate capital gains tax, the seller can take back a promissory note from the buyer.

Critical Tax Calculations

1. Exclusion of Like-Kind Property from Basis: Under Section 453(f)(6), the fair market value of the qualifying replacement property received tax-free under Section 1031 is excluded from the contract price and total contract calculations under Section 453.
2. Basis Allocation: The seller's adjusted basis in the relinquished property is first applied dollar-for-dollar to the replacement property received, up to its fair market value. Any excess basis is then assigned to the installment note.
3. Boot Deferral via Note: Because the seller holds an installment note for the difference rather than cash, tax on the boot is deferred until principal payments are made on the note in subsequent years. This prevents an immediate, expensive tax event during an incomplete 1031 exchange.
