When I talk to real estate investors about 1031 exchanges, the most common question I get isn't about property types or value requirements—it's about timing. And honestly, I get it. From the moment you close on the for sale property, the timeline begins. From day 1, you have 45 days to choose 3 potential replacement properties.
These aren't suggestions—they're hard deadlines that can make or break your entire exchange. However, with the exception of extensions granted by the IRS due to disasters, there are no extensions regarding the 45-day Identification period. Failure to adhere to the rules set forth in the Tax Code will cause the 1031 Exchange to be disqualified resulting in payment of the taxes the Exchanger was attempting to defer. Miss them, and you're looking at a massive tax bill instead of tax-deferred wealth building.
Let me break down exactly what these timelines mean and how to navigate them successfully.
The Two Critical Deadlines You Cannot Miss
The 45-Day Identification Rule
The identification period begins on the day you sell your relinquished property. From that date, you have 45 calendar days to identify potential replacement properties. This period starts the day after you close on the sale of your relinquished property.
Here's what you need to know:
- It's calendar days, not business days - These two windows run concurrently, and they are firm. There are no extensions granted by the IRS for weekends, holidays, or other delays.
- Written identification is required - This identification must be made in writing, signed by you, and delivered to a party involved in the exchange—typically your Qualified Intermediary.
- You can change your mind during this period - A taxpayer has the ability to substitute a new replacement property or properties by revoking a previous identification in the same manner as originally identified and subsequently identifying new replacement properties as long as this is done, in writing and meeting all other identification requirements, within the 45-day identification period.
The 180-Day Exchange Period
The exchange period allows a total of 180 calendar days from the sale of the relinquished property to complete the purchase of the replacement property.
Critical point: By the end of the 180-day window, the exchange should be completed to qualify for 100% tax deferment. One of the most common misconceptions about like-kind exchanges is that property owners have 45 days, then 180 days, for a total of 225 days. This is not the case. You must complete the entire process within 180 days.
The Tax Return Deadline Trap Most Investors Don't Know About
Here's where it gets tricky. However, if your tax return is due before the 180 days are up, you must close on the replacement property before filing—unless you file for an extension.
Real-World Example
Let's say you sell your property on December 15th. Your 180-day deadline would normally be June 13th of the following year. But if you're an individual taxpayer, your tax return is due April 15th—which comes before your 180-day deadline.
Here's an example – let's say that you close on the sale of your relinquished property on December 20th. If you are an individual, you would file your tax return on April 15th. As you can see, there are not 180 days between December 20th and April 15th. Unless you ask for a filing extension from the IRS, you will not have 180 days to complete your exchange.
The solution: You can request an extension if the 1031 exchange period overlaps your regular tax filing due date. This extension postpones the tax filing deadline by six months, giving you the full 180 days to complete the exchange.
Property Identification Rules: The Three-Property Rule
During your 45-day identification period, you need to understand the property identification rules:
The Standard Three-Property Rule
The three-property rule states that you can identify up to three replacement properties, regardless of their individual or aggregate fair market value. You do not need to acquire all three; you can acquire any number of them, so long as each replacement property you acquire is among the identified properties.
What Happens If You Need More Options?
You can identify more than three (3) replacement properties as long as the total (aggregate) fair market value of all the identified replacement properties does not exceed 200% of the total (aggregate) Gross Sale Price of your relinquished property(ies) sold in your 1031 Exchange.
95% rule: The 95% rule says that a taxpayer can identify more than three properties with a total value that is more than 200% of the value of the relinquished property, but only if the taxpayer acquires at least 95% of the value of the properties that they identified. However, if you do not acquire and close on at least 95% of the value of the identified like-kind replacement properties the entire 1031 Exchange transaction will be disallowed.
What Happens When You Miss These Deadlines?
The consequences are severe:
- Missing this deadline or failing to properly identify properties can disqualify the entire exchange.
- If you don't identify a property by the end of day 45, the exchange becomes invalid. The sale of your relinquished property loses the tax-deferment benefits. Any funds left in the escrow account after the 180-day deadline will be returned to you, and those funds are subject to capital gains and depreciation recapture taxes.
Rare Exceptions: When Extensions Might Be Possible
When an unforeseen crisis occurs, it may be difficult for taxpayers to adhere to the strict deadlines for 1031 Exchanges. Because of this, the Internal Revenue Service through Revenue Procedure 2018-58, allows certain taxpayers impacted by federally declared disasters to get more time to meet tax-related deadlines including those for 1031 Like-Kind Exchanges.
But don't count on these exceptions—they're truly rare and only apply during major disasters.
Smart Strategies to Navigate These Timelines
Start Your Search Early
Start your search for replacement properties early. You aren't required to wait until your relinquished property is on the market or sold before looking for your replacement investment.
Use All Three Identification Slots
Even if you think you know which property you want, you can identify as many as three potential replacement properties with the intention of acquiring one, two, or all three of them. Should your first choice fall through between Day 45 and Day 180, you can acquire either of your other two identified properties, and your exchange will be fine.
Get Your Team in Place Early
Have your Qualified Intermediary lined up before you put your property on the market. You don't know how quickly a unit may sell, and you don't want to scramble to find someone.
Why Professional Guidance Matters
The IRS has strict rules and requirements that need to be followed to complete a 1031 exchange. These tight deadlines make the process challenging, often putting exchangers under pressure to identify and close on replacement properties to defer capital gains tax liability.

The Bottom Line
Timing is everything in a 1031 exchange, and the IRS enforces strict deadlines to ensure the transaction qualifies for tax deferral. The 45-day and 180-day rules are strict deadlines that are non-negotiable. If you miss these deadlines, your 1031 exchange will not be valid, and you could lose the tax deferral benefits that come with it.
But with proper planning and the right team, these timelines are completely manageable. The key is understanding them upfront and building your strategy around them—not trying to work around them after the fact.

Frequently Asked Questions
Q: Can I get an extension on my 45-day or 180-day deadlines?

A: Yes, all calendar days count. If your deadline falls on a weekend or holiday, it doesn't extend to the next business day.

A: Your exchange fails, and you'll owe capital gains taxes on your relinquished property sale. This is why having backup properties identified is crucial.
