1031 Exchange Deadline Calculator
Track your important 1031 exchange deadlines and requirements
Important Considerations
Qualified Intermediary: You must use a QI to facilitate the exchange. Funds cannot be in your possession during the exchange period.
Like-Kind Property: Replacement property must be of "like-kind" - generally any real estate held for investment or business use in the U.S.
Equal or Greater Value: To defer all taxes, the replacement property must be of equal or greater value and all equity must be reinvested.

Introduction to 1031 Exchange Deadlines
A 1031 Exchange Deadline Calculator is a specialized tool designed to help real estate investors track critical deadlines for a like-kind exchange under Section 1031 of the U.S. Internal Revenue Code. This calculator ensures compliance with IRS rules by accurately counting down the 45-day identification period and the 180-day exchange period from the sale of the relinquished property.
What is a 1031 Exchange?
A 1031 exchange allows real estate investors to defer capital gains taxes by reinvesting the proceeds from the sale of one property into the purchase of another "like-kind" property. This powerful tax strategy requires strict adherence to IRS deadlines and regulations.

Key Deadlines in a 1031 Exchange
The IRS mandates strict timeframes for completing a 1031 exchange:
A. Day 0 – Sale of Relinquished Property (Closing Date)
- The exchange timeline starts the day after the sale closes.
B. 45-Day Identification Period
The investor must identify potential replacement properties in writing by midnight of the 45th day.
C. Rules for Identification
- Three-Property Rule: Identify up to 3 properties without regard to value.
- 200% Rule: Identify any number of properties as long as their total value does not exceed 200% of the sold property's value.
- 95% Exception: Identify unlimited properties if the investor acquires 95% of their total value.
D. 180-Day Exchange Period
- The investor must close on the replacement property within 180 days of the initial sale (or by the tax filing deadline, whichever comes first).
Pro Tip: Start Early
Begin identifying potential replacement properties as soon as you list your relinquished property. The 45-day window passes quickly, and having backup options can save your exchange if your first choice falls through.

Example Calculation
Scenario: An investor sells Property A on June 1, 2025.
A. 45-Day Identification Deadline:
- June 2 (Day 1) → July 16, 2025 (45th day).
B. 180-Day Exchange Deadline:
- June 2 (Day 1) → November 28, 2025 (180th day).
C. Tax Filing Deadline Check:
- If the investor's tax return due date (e.g., April 15, 2026) is later than the 180-day period, the full 180 days apply.
- If the 180 days extend beyond the tax filing deadline, the deadline shortens to the tax due date.
Critical Deadline Warning
Missing either the 45-day identification deadline or the 180-day exchange deadline will disqualify your entire 1031 exchange, resulting in immediate capital gains tax liability. There are no extensions for weekends, holidays, or personal delays.

Frequently Asked Questions
What happens if I miss the 45-day identification deadline?
Missing the 45-day identification deadline disqualifies your entire 1031 exchange. You'll be required to pay capital gains taxes on the sale of your relinquished property, and there are no exceptions or extensions granted by the IRS.
Can I identify more than three replacement properties?
Yes, but you must follow either the 200% Rule (total value of identified properties doesn't exceed 200% of the sold property's value) or the 95% Exception (you acquire at least 95% of the value of all identified properties).
What if my 180-day period ends on a weekend or holiday?
Unlike some tax deadlines, 1031 exchange deadlines are not extended for weekends or holidays. If your 180th day falls on a Saturday, Sunday, or legal holiday, your deadline is still that day.
Can I extend the 180-day exchange period?
No, the 180-day period cannot be extended for any reason. The only potential shortening occurs if your tax return due date (including extensions) comes before the 180th day.
What qualifies as "like-kind" property for a 1031 exchange?
For real estate, nearly any type of investment or business property qualifies as like-kind to another. For example, you can exchange an apartment building for raw land, a commercial building for a rental house, etc. Personal residences do not qualify.
