The second deadline in a 1031 exchange gets less attention than the 45-day identification window, but it is the one that actually closes the file. An investor has 180 calendar days from the closing of the relinquished property to complete the purchase of the replacement property, and that window runs concurrently with the 45-day period rather than starting after it ends. For an Orlando investor juggling closing logistics and a tax return, the interaction between the two deadlines matters as much as either number on its own.
How the 180 Days Actually Run
The 180-day period begins on the same date as the 45-day identification window: the closing date of the relinquished property. It does not begin when identification is completed or when a replacement contract is signed. That means the 45 days for identifying property are the first 45 of the 180 total, leaving 135 remaining calendar days to close on the replacement once the list is locked. There is no separate restart for the closing phase.
The Tax Return Due Date Can Shorten the Window
The 180-day period is also capped by the due date of the investor's federal tax return for the year the relinquished property was sold, including extensions. An investor who sells in November has a return due the following April 15, which falls well short of the full 180 days. Filing an extension pushes that internal deadline out to October 15, restoring the full window. Investors who close late in the calendar year and do not plan to file an extension should confirm which deadline actually governs their exchange before assuming they have the full 180 days.
What Has to Happen Before Day 180
- The replacement property purchase must actually close, not just be under contract
- Title must transfer to the same taxpayer that sold the relinquished property
- Exchange proceeds held by the qualified intermediary must be applied to the purchase
- Any required financing has to fund on schedule, since a delayed lender is not a valid reason to extend the deadline
Why Central Florida Closings Need a Buffer Built In
Financing on commercial and multifamily property in the Orlando market can take longer to fund than a residential loan, particularly when a lender is underwriting a property in Lake Mary or along the Beachline that does not have a long operating history under the current owner. Building a closing timeline that assumes the last week of the 180 days as a cushion, rather than the target date itself, gives the file room to absorb a lender's final conditions without forcing a last-minute scramble.
What Happens If Day 180 Passes Without a Closing
There is no cure period. If the replacement purchase has not closed by the 180th day, the exchange fails, the deferral is lost, and the qualified intermediary returns the held proceeds to the investor as a taxable event in the year the exchange period ends. A failed exchange this close to the finish line is almost always a timeline problem rather than a property problem, which is why tracking the closing date against the deadline from day one matters more than the identification itself once the list is locked.
Common 1031 Exchange Questions
Does the 180-day period start after the 45-day identification window ends?
No. Both periods start on the same date, the closing of the relinquished property. The 45 days for identification are the first 45 of the total 180.
Can my tax return due date shorten the 180-day exchange period?
Yes. The exchange must also complete by the due date of the return for the sale year, including extensions, whichever comes first between that date and the full 180 days.
Does filing a tax extension help with the 180-day deadline?
It can. Filing an extension pushes the return due date to October 15, which restores the full 180-day window for exchanges that close later in the year.
Is being under contract on the replacement property enough to meet the deadline?
No. The purchase has to actually close and title has to transfer by day 180. A signed contract with a pending closing does not satisfy the deadline.
What happens if financing delays push my closing past day 180?
The exchange fails and the deferral is lost. A lender's funding delay is not grounds for an extension, which is why financing timelines need a buffer built in well before the deadline.
Is there any way to get more than 180 days?
Only through a narrow, formally declared disaster extension for specific affected counties. There is no general extension available for financing delays or personal scheduling conflicts.
