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.
1. Introduction
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.
2. Key Deadlines in a 1031 Exchange
The IRS mandates strict timeframes for completing a 1031 exchange:
Day 0 – Sale of Relinquished Property (Closing Date)
The exchange timeline starts the day after the sale closes.
45-Day Identification Period
The investor must identify potential replacement properties in writing by midnight of the 45th day.
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.
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).

A well-designed calculator includes:
A. Input Fields

4. Example Calculation
Scenario: An investor sells Property A on June 1, 2025.
45-Day Identification Deadline:
June 2 (Day 1) → July 16, 2025 (45th day).
180-Day Exchange Deadline:
June 2 (Day 1) → November 28, 2025 (180th day).
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.
5. Benefits of Using a 1031 Exchange Deadline Calculator

6. Limitations & Considerations
