Do I get 45 days plus another 180 days?
No. The identification and exchange periods run from the transfer of the relinquished property. The tax-return due date, including extensions, can shorten the exchange period.
1031 Exchange Readiness Checklist
Questions to organize before selling investment real estate in a potential Section 1031 exchange.
Reviewed by Jeff Huang, CPA, MBA · Last reviewed October 9, 2026 · Sources checked October 10, 2026A potential 1031 exchange should be discussed before the relinquished property closes. The taxpayer, property use, qualified intermediary, identification deadline, exchange deadline, replacement-property value, financing, and cash retained all affect whether the intended deferral can work.
Check property use first
Section 1031 generally applies to qualifying real property held for investment or business use. A personal residence or property held primarily for sale is outside that general rule. Mixed use, related parties, and ownership changes require closer review.
IRS Form 8824 instructions — qualifying propertyPut the exchange plan in place before closing
Coordinate the qualified intermediary and closing instructions before the sale. Receiving or controlling the proceeds can prevent the intended deferred-exchange treatment. An exchange is more than selling a property and buying another later.
IRS Publication 544 — deferred exchange and receipt of proceedsTrack both deadlines from the sale transfer
For a standard deferred exchange, identify replacement property in writing within 45 days. Receive it by the earlier of 180 days or the tax-return due date, including extensions, for the sale year. These periods run together; the 180-day period does not begin after day 45. Check whether specific IRS disaster relief applies.

Cash retained, debt relief, and other property can affect current taxable gain. Model the replacement property’s basis and financing as well as the cash needed outside the exchange.

- How the relinquished property has been held and used
- Exact taxpayer or entity that owns it
- Expected closing date
- Qualified intermediary engagement status
- Replacement-property search and financing
- Cash needed outside the exchange
How the rules compare
| Step | What to organize | Planning question |
|---|---|---|
| Before the sale closes | Owner, property use, intermediary, and escrow instructions | Is the intended structure ready? |
| Within the identification period | Written property identification and backup choices | Can the choices meet the identification rules? |
| Before the exchange deadline | Purchase terms, financing, and closing readiness | Can the identified property be received in time? |
A simple planning example
An investor wants to exchange a rental but also needs cash for personal expenses. Before closing, the team compares a full sale with an exchange that retains some cash. The comparison includes current tax, loan payoff, replacement financing, and reserves. Keeping cash may produce taxable gain even when the real-property exchange otherwise qualifies.

Frequently asked questions
Can I use an exchange for my own home?
A home used only personally generally does not qualify. Mixed-use and former rental property require a separate facts-based review.
Does buying another property automatically defer the gain?
No. Property use, ownership, proceeds control, identification, timing, and the exchange structure all matter.
Prepare before the decision is final
Gather the deed, entity documents, purchase and depreciation records, sale contract, proposed closing date, loan payoff, intermediary agreement, replacement-property choices, and financing plan. Confirm who owns each property and who will receive the exchange funds.
The intro call confirms fit, timing, and scope. Detailed calculations and recommendations require a paid engagement. Use TaxDome when the team requests sensitive records.
