A 1031 exchange offers real estate investors a powerful tax-deferral strategy, but it comes with strict IRS deadlines that cannot be missed. Missing these deadlines will cause the exchange to fail and will trigger a taxable event.

When Do 1031 Exchange Timelines Start?

Day 0 of the exchange period is the closing date of the sale of the investor’s relinquished property, or the property being sold. From day 0, exchangers have 45 days to identify replacement properties and 180 days to close on those identified properties. The 45-day identification period and 180-day exchange period run concurrently, meaning both timelines begin on the day you close on your relinquished property.

These deadlines include all calendar days, including weekends and holidays. There are no extensions in a 1031 exchange. If your 45th or 180th day falls on a weekend or holiday, be sure to complete the identification and purchase of replacement properties beforehand to avoid a failed exchange.

The 45-Day Identification Period

From the closing date of the sale, exchangers have 45 days to submit a list of potential replacement properties to the Qualified Intermediary (QI). These identified properties must be like-kind, meaning properties intended to be held for business or investment use. The identified properties must be submitted to the QI in writing, and the property descriptions must be clear, using a street address or legal description. It is essential to begin identification early, even before the sale closes, to ensure you have suitable options that meet your investment goals.

You can submit the identification form at any time within the 45-day window. If you need to make changes, you may revoke your original submission and resubmit a new form, as long as it’s within the 45 days. However, after the 45th day, investors can use exchange funds only to purchase replacement properties listed on the identification form they submitted.

If you don’t submit the identification form by midnight on the 45th day, the exchange will fail, and your funds will be returned as taxable boot. However, if you did submit a form, the only way to withdraw funds from the QI account is to purchase an identified property or wait until the 180-day period ends, after which the funds will be returned as taxable boot.

How Many Properties Can You Identify?

There are three identification rules exchangers can use to identify replacement properties and qualify for tax deferral under IRS guidelines:

1. Three-Property Rule: Allows the taxpayer to identify up to 3 replacement properties, regardless of their value.
2. 200% Rule: If a taxpayer identifies more than 3 replacement properties, the combined value of those properties cannot exceed 200% (or double) the value of the property sold.
3. 95% Rule: If the taxpayer identifies more than 3 properties and the combined value of those properties exceeds 200% of the value sold, the taxpayer must purchase at least 95% of the value of the identified properties.

The 180-Day Exchange Period

From the closing date of the sale, you have 180 days to close on any identified replacement properties you plan to purchase. This deadline is strict: if you fail to close by the end of the 180th day, even due to unexpected delays, the exchange will not qualify for tax deferral. Any funds remaining in the QI account after the 180th day will be returned to you as taxable boot. It’s important to work closely with your Qualified Intermediary, lender, and real estate professionals to ensure all transactions are finalized on time.

Important: The 180-day period may be shortened by your tax return due date (typically April 15th). 1031 exchanges must be reported on the tax return for the tax year of the sale of the relinquished property. If your tax return is due before the 180th day, your exchange must be completed by the tax filing deadline unless you file for an extension. You can file for an extension on your tax return to take advantage of the full 180-day exchange period, but you cannot file for an extension on the exchange itself.

Example: Your investment property’s closing date is December 1st, 2025. Your 45th day will be January 15th, 2026, and your 180th day will be May 30th, 2026. Since your property sold in 2025, your exchange must be reported on your 2025 tax return, which is due on April 15th, 2026. If you don’t file for an extension on your tax return, your exchange must be completed by the tax filing deadline. Filing for a tax return extension lets you take advantage of the full 180-day exchange period.

Missing either the 45-day identification deadline or the 180-day exchange deadline will disqualify your exchange from tax deferral, making any remaining funds taxable.
