- Missing any deadline disqualifies tax deferral.
What Is the Like Kind Exchange Timeline Under IRS Rules?
A like kind exchange timeline is the set of strict IRS deadlines in Section 1031 for selling investment real estate and rolling proceeds into qualifying replacement property. Missing these deadlines—even by one day—results in immediate tax on all gain. Timeline compliance is even more important in 2026 because new federal law allows 100% bonus depreciation for many replacement properties. Both deferral of capital gains and first-year deduction planning require perfect timing.
What Are the 45-Day and 180-Day Rules?
The two core deadlines in a like kind exchange:
- 45-day identification period: Within 45 days of closing on your old property, you must identify (in writing) potential replacement properties to your qualified intermediary.
- 180-day exchange period: Purchase (close on) the replacement property within 180 days of selling the relinquished property. The 180 days runs simultaneously with the 45 days.
No extensions except for federally declared disasters. File a tax return extension if your exchange period would otherwise end after your normal filing deadline to ensure you receive the full 180 days.
| Event | Deadline | Action |
|---|---|---|
| Sale Closing | Day 0 | Relinquished property sold, intermediary receives proceeds |
| Replacement Identification | By Day 45 | Submit identification notice in writing |
| Exchange Deadline | By Day 180 | Close on identified property |
What Bonus Depreciation Rules Apply to Your Exchange in 2026?
Congress restored 100% bonus depreciation for property placed in service after July 4, 2025, and before January 1, 2031 per the One Big Beautiful Bill Act. Investors who purchase qualifying real estate in a 2026 like kind exchange and use MACRS can apply this deduction. Confirm construction and in-service dates fall within allowed windows and do not elect ADS (Alternative Depreciation System) unless required.
What Is the Difference Between MACRS and ADS Depreciation?
MACRS (Modified Accelerated Cost Recovery System) is the default IRS depreciation schedule for property placed in service in the U.S. It allows for accelerated deductions and is required to take bonus depreciation in 2026. ADS uses a longer, straight-line schedule, and using it disqualifies investors from bonus depreciation. Some investors must use ADS for property outside the U.S. or when specifically required by tax law.
| Feature | MACRS | ADS |
|---|---|---|
| Bonus Depreciation | Allowed (100% in 2026) | Not Allowed |
| Residential Recovery Period | 27.5 years | 30 years |
| Commercial Recovery Period | 39 years | 40 years |
What Happens If You Miss a Like Kind Exchange Deadline?
Free Tax Write-Off FinderFailure to properly identify replacement property within 45 days or to close within 180 days causes the entire gain from the sale to become immediately taxable. Late filings, missed or vague identification, and failing to use a qualified intermediary are the most common reasons for failed exchanges.
How Do You Complete a Compliant 1031 Exchange in 2026?
- Engage a qualified intermediary (QI) before the sale closes.
- Close on the relinquished property—QI receives proceeds.
- Identify replacement properties within 45 days (in writing).
- Close on the identified replacement property within 180 days.
- Depreciate new property using MACRS. Confirm eligibility for bonus depreciation.
- File IRS Form 8824 with your federal return for the tax year of the sale.
- If the sale occurs late in the year, file a tax extension to give yourself the full 180 days.

Frequently Asked Questions
How does the like kind exchange timeline begin?
The timeline starts on the closing date when you sell your property (Day 0). Both the 45-day and 180-day clocks start at this moment.
Are there any IRS exceptions to timeline rules?
Only for federally declared disaster areas announced by the IRS via official notice. All other delays or hardships do not qualify for extension.
What is a qualified intermediary?
A neutral third party (not your attorney, CPA, or agent) who holds proceeds and structures the exchange. Engaging a QI is mandatory—if you handle the money, the exchange is invalid.
Which IRS form reports a 1031 exchange?
Form 8824, attached to your federal tax return for the year of the relay (https://www.irs.gov/forms-pubs/about-form-8824).
What if I receive boot in the exchange?
Any cash or non-like-kind property received is taxable in the year of the exchange, even if the rest qualifies. Only full, like-kind exchanges receive total deferral.
