1031 Exchange Dates

1031 Exchange Timeline

Enter your property closing date to calculate the critical deadlines for your 1031 exchange.

Closing Date * Show Deadlines

45-Day Identification Deadline

This is your identification deadline. You must identify potential replacement properties and submit the list to your Qualified Intermediary by this date.

180-Day Exchange Deadline

This is your exchange completion deadline. You must close on your replacement property by this date to complete the 1031 exchange.

Important: The 180-day deadline may be shortened if your tax return due date (including extensions) comes before the 180th day. Consult with your tax advisor for specific guidance.

A 1031 Exchange Time Limit, often called the Exchange Period, sets IRS deadlines that must be followed to defer capital gains taxes when exchanging investment or business real estate.

45-Day Rule: Starting the day after you close on the sale of your original property (the relinquished property), you have 45 calendar days to identify potential replacement properties in writing. The identification must be clear, unambiguous, and delivered to your qualified intermediary or other permitted party. No extensions are allowed—even for weekends or holidays.

180-Day Rule: You must complete the purchase of one or more identified replacement properties within 180 calendar days of selling the relinquished property or by the due date of your tax return for that year (including extensions), whichever comes first.

Missing either deadline disqualifies the exchange, making the sale fully taxable. Timing is everything in a 1031 exchange, so planning should begin well before the original property closes.
