Key Takeaways
A simultaneous exchange closes the sale and purchase on the same day. It was the original form of 1031 exchange but is rare today because the delayed exchange structure is safer and easier. Simultaneous exchanges still happen in pre-arranged transactions and certain commercial deals, but most advisors recommend the delayed structure for better protection.
A simultaneous 1031 exchange is the simplest form: you sell your property and buy replacement property on the same day. Both deeds transfer at once, and the transaction closes as a single event.
Why it is rare
Before the landmark Starker v. United States decision in 1979, simultaneous exchanges were the only option. You had to find a counterparty willing to swap at the same time. The Starker ruling established that Section 1031 does not require same-day closing, which opened the door to delayed exchanges.
Delayed exchanges dominate today because they eliminate the need for perfect synchronization. You sell on your schedule, then have 45 days to identify and 180 days to close on a replacement. The other party does not need to know or care that you are doing an exchange.
Where simultaneous exchanges still appear
- Pre-arranged commercial transactions. Two sophisticated parties agree in advance to coordinate closings on the same day, often through the same title company.
- Related-party swaps. Family members trading properties may coordinate simultaneous closing. (Note: related-party rules still apply, including the two-year hold requirement.)
- Development deals. A developer trading a parcel to a government agency or institution where the counterparty needs immediate possession.
How it differs from a delayed exchange
In a simultaneous exchange, a qualified intermediary is not structurally required because no one holds proceeds between transactions. However, most professionals involve a QI anyway for documentation. If the IRS later questions the exchange, a QI paper trail is stronger than none.
All other 1031 rules still apply: like-kind property, held for investment or business use, same taxpayer on both sides, boot rules, and Form 8824 reporting.
The bottom line
Simultaneous exchanges are legal and straightforward, but impractical in most situations. The delayed exchange structure offers the same tax benefit with far more flexibility. Unless you have a specific reason to coordinate a same-day closing, the delayed exchange is the standard approach.
For help determining which exchange structure fits your situation, connect with a qualified professional.
The Bottom Line
Simultaneous exchanges are possible but coordination-heavy. The delayed exchange structure is now standard because it's more flexible, protects both parties, and leverages the qualified intermediary system that the IRS actually prefers.
