1031 Exchange Timeline: The 45-Day and 180-Day Rules

Missing a 1031 deadline is the most common way exchanges fail, and the IRS almost never extends them. Here is how the timeline works, step by step.

Monthly planner for tracking 1031 exchange deadlines

Before Closing: Engage a Qualified Intermediary

The clock hasn’t started yet, but this step can’t wait. The exchange agreement with your QI has to be signed and assigned into the sale contract before the relinquished property closes. Once you have the proceeds, it’s too late.

Day 0: Sale of the Relinquished Property Closes

Net proceeds are wired to 1031 Ventures and held in a qualified escrow account. The 45-day and 180-day periods both start the day after closing.

Day 45: Identification Deadline

By midnight of day 45, you must identify potential replacement properties in a signed, written document delivered to your QI. Describe each property clearly, by street address or legal description, or by lease, unit and county for mineral interests. You can identify up to three properties of any value, or more under the 200% or 95% rules. See the identification rules.

Any property you close on within the first 45 days counts as identified.

Day 180: Exchange Deadline

You must close on the replacement property by day 180. Because both periods run at the same time, you only have 135 days left once the identification window closes.

Watch the tax return trap: the exchange period ends on day 180 or on the due date of your tax return for the year of the sale, whichever comes first. If you sell late in the year, for example in November, file an extension so you keep the full 180 days.

Do Weekends and Holidays Extend the Deadlines?

No. Both deadlines are calendar days. If day 45 falls on a Sunday, the deadline is that Sunday. The only extensions are for federally declared disasters, when the IRS issues specific relief.

What If I Miss a Deadline?

If you identify nothing by day 45, or can’t close by day 180, the exchange fails and the sale is taxed normally. Depending on timing, the funds may stay restricted until the exchange period ends. If a deal looks shaky, talk with us early. Identifying backup properties is the best insurance.
