Investor WorkspaceA little clarity for your next decision.
By Jerry Baker
The 45-day identification period is the deadline to name replacement property in a deferred 1031 exchange. This guide explains how the clock works, what a valid written identification needs, and how the three-property, 200%, and 95% rules affect your choices.
When you sell property as part of a deferred exchange, you cannot leave your replacement choices open until the final closing deadline. You must identify replacement property within a separate, shorter period.
The clock starts when you transfer the property you are giving up. It ends at midnight on the 45th day after that transfer. You must also receive the listed property within the separate exchange period. These are two different tasks. [1]
Identification means following the written notice rules. It does not mean buying a property, putting it under contract, or proving it is a good investment. Those issues still need attention.
I would treat this as the date when your list becomes fixed under the ordinary rules. You want that list to reflect choices you have actually examined, with room for a realistic backup plan. A long list of deals you would never buy is not much of a plan.
Start with the actual transfer date, which is usually the sale closing date. Do not start from the day you listed the property, accepted an offer, or received an estimated closing statement. Have your qualified intermediary and tax adviser confirm the date for your transaction.
For ordinary counting, the next date is day one. Count weekends and holidays. Do not replace 45 calendar days with 45 business days or add an extra day because the deadline feels inconvenient.
Consider an illustration with a transfer on March 17, 2027. The 45th day afterward is May 1, 2027, a Saturday. The 180th day afterward is September 13, 2027. That later date remains subject to the earlier tax-return deadline rule. This example assumes ordinary rules and no special relief.
A Saturday identification date is a reason to finish sooner, not to assume Monday is acceptable. Ask the people handling the exchange for their schedule well before that week arrives.
You may sell more than one old property in the same exchange. If so, the first transfer starts both clocks. A later sale in that exchange does not restart the clock. Separate exchanges require their own analysis; do not combine or separate files just to get a preferred date. [1]
The identification period is not followed by a fresh 180 days. Both clocks begin with the same transfer. Under the ordinary rule, the exchange must finish by the earlier of day 180 or the due date of your tax return for the transfer year, including extensions. [2]
A filing extension may matter when a late-year sale puts the normal return due date before day 180. It does not turn a 180-day exchange period into a longer one. Your CPA should check your actual filing calendar rather than rely on an example for a different taxpayer.
| Milestone | What must happen | What it does not do |
|---|---|---|
| Before the sale | Arrange the exchange and fund controls | Reserve every future investment |
| By the identification deadline | Identify replacement property using the required process | Complete the purchase for you |
| By the exchange deadline | Receive qualifying, properly identified replacement property | Excuse a missed identification deadline |
I would keep both dates at the top of the file. A calendar reminder called “1031 deadline” is too vague when two different obligations are involved.
The Treasury rules call for a written document signed by the taxpayer that designates the replacement property. The property must be described clearly enough to identify it without guessing. The document must be sent to a permitted recipient before the identification period ends. [1]
A legal description, street address, or distinct property name can meet the description requirement. The right format depends on the property. A broad category such as “an apartment building in Texas” does not identify a specific asset.
For a fractional interest or a portfolio, have the intermediary and counsel check the actual description, interest, and property count. Do not rely on a marketing nickname when several offerings use similar names.
I would ask for a completed sample before the deadline week. Check the taxpayer name, exchange file number, property details, signature, and date. If attachments describe the properties, make sure those attachments travel with the signed notice.
A blank form sitting in your inbox is not an identification. Neither is telling someone by phone that you like an investment. Keep the final signed version and the evidence of how it was sent.
The regulations allow the notice to go to the person obligated to transfer the replacement property, or to another permitted person involved in the exchange. A qualified intermediary is a common recipient. You cannot just send it to yourself. The rules also limit who else can fill this role. [1]
The transferor rule and the rule for other people are not identical. In particular, the regulation allows identification to the obligated transferor even if that person is otherwise disqualified. Your own adviser is not automatically an acceptable substitute.
The federal language includes hand delivery, mail, fax, and other sending methods. It should not be rewritten as a universal rule that only a QI's actual receipt can count. Still, for practical planning, I would confirm the delivery method with the QI and obtain a written acknowledgment.
That confirmation helps catch a wrong address, missing attachment, or unreadable file while there is still time to fix it. A last-minute transmission dispute is a poor use of an exchange deadline.
The IRS also describes an identification made within a written exchange agreement signed by all parties. Have counsel verify that route rather than assume any purchase agreement meets the identification rules. [2]
This rule lets you name up to three properties. For this test, there is no cap on their total fair market value. You do not receive three slots for every old property sold in the same exchange. [1]
Imagine selling an investment property worth $1 million. You identify three potential replacements worth $900,000, $1.2 million, and $1.4 million. Their combined value is $3.5 million. The value alone does not break the three-property rule.
That does not mean you must buy all three. It also does not mean buying any one will fully defer your gain. The tax result still depends on the complete exchange, including proceeds, liabilities, expenses, and any cash or other property received.
The useful question is whether each identified choice could realistically fit. If one cannot obtain financing and another has unresolved title problems, three names on paper may leave only one workable option.
The 200% rule can allow more than three properties on the list. Add up the fair market value of all the choices. That total must not exceed twice the value of all the old properties sold in the exchange. The rule sets the date to use for each value. [1]
For an ordinary existing-property example, use the old property's value when transferred and the replacement properties' values at the end of the identification period. Special rules apply to property being produced.
If the old property's value is $1 million, the ceiling is $2 million. Five hypothetical choices worth $500,000, $400,000, $350,000, $300,000, and $250,000 total $1.8 million. That list fits within the value limit, assuming the counts and values are correct.
Now add a sixth property worth $400,000. The total becomes $2.2 million. The list has more than three properties and exceeds the 200% limit. Adding a “backup” has created a problem rather than solved one.
Fair market value is not reduced by the mortgage for this purpose. A $1 million old property with $600,000 of debt still gives a $2 million value ceiling in this example, not an $800,000 ceiling based on $400,000 of equity.
Keep a worksheet showing the property, ownership interest, value, source of that value, and total. Ask your advisers how fractional interests and multiple parcels should be counted before using the worksheet to make a decision.
If a list exceeds both the property-count and value limits, the ordinary result is that no replacement property is treated as identified. The regulations contain limited exceptions, including qualifying property already received during the identification period and the 95% rule. [1]
The 95% rule looks at value, not how many properties you buy. Before the exchange period ends, you must receive property from your list. What you receive must be worth at least 95% of the total value of everything on that list. The rule has its own valuation timing.
Assume a list that exceeds both main limits has a combined value of $3 million under the applicable measurements. Acquiring $2.7 million equals 90%, which is too little. Acquiring $2.85 million equals 95%. Other exchange requirements still apply.
This is not permission to make an enormous list and choose whichever single deal works out. Financing, seller cooperation, and closing logistics have to support nearly the entire list by value.
I would not treat the 95% rule as a casual safety net. If a plan depends on it, the tax and legal review belongs before the list is finalized.
You may revise your choices during the identification period, but the paperwork matters. Put the removal in writing and sign it. Send it within the period to the person who received the first notice. Identifications made in an exchange agreement have their own amendment or notice requirements. [1]
Sending a new list does not always erase an old one. Old choices can still count if you did not properly remove them.
Suppose you identify A, B, and C, then decide to use D instead of A. Ask the QI to confirm the exact signed revocation and new identification steps. Do not rely on a casual message saying, “Let's go with D.”
Before the period ends, I would request one final record showing which properties remain identified. Compare it with every prior notice. Resolving a duplicate or stale choice while the clock is still running is much easier than arguing about it afterward.
Property you receive before the 45 days end is treated as identified. This does not make it invisible when counting the rest of your choices. [1]
For example, receiving one replacement property during the period normally uses one of the three slots if you are relying on that rule. It does not leave three more unlimited-value slots.
Early closing can reduce uncertainty about that purchase. It does not cure an invalid list for other properties or establish that the whole exchange fully defers tax.
If you are making several purchases, update the same worksheet after each closing. Track what was actually acquired, what remains identified, how much cash is left, and what debt or extra cash is still needed.
A qualifying Delaware statutory trust can provide an interest in real estate that receives 1031 treatment under the conditions described in IRS Revenue Ruling 2004-86. That does not make every trust interest eligible or remove the identification rules. [4]
Ask for the exact guidance for that offering. Check the property descriptions and how the interests are counted and valued. Do not assume a portfolio marketed under one name always uses only one identification slot.
For my review, availability is a separate column. An identified offering can fill, change status, or become unsuitable before you fund it. A stated minimum investment can also limit how you divide the exchange.
The deadline should not replace due diligence. I still want to understand the manager, properties, debt, fees, business plan, and exit limits. A property that can close quickly may still be a poor match for your needs.
The Treasury rule uses midnight for the end of the identification period. That does not promise that your QI, bank, sponsor, title office, or adviser will be available until then.
Ask each party for its operational cutoff and time zone. A same-day wire may have an earlier cutoff than a signed document. A sponsor may need time to review a subscription even when the money is ready.
I would aim to complete the identification well before the final business day. If something changes, there is still room to verify the revised papers and reach a real person.
Keep reminders for separate tasks: review options, confirm values, finalize the list, sign, send, and confirm the record. Setting one alarm for 11:30 p.m. on day 45 is technically a reminder. It is not the approach I would choose.
A property listed too late generally fails the identification test. Closing quickly afterward does not make the late notice timely. The rules separately protect property received within the first 45 days. The closing history matters. [1]
Tell your CPA and QI immediately if a deadline may have been missed. Provide the transfer date, signed notices, sending records, and completed purchases. Do not backdate a document or quietly substitute a new file.
Special disaster relief can affect certain deadlines for eligible taxpayers. The IRS publishes notices describing covered areas, dates, and available relief. A disaster headline by itself does not establish that your exchange qualifies. [3]
Have your advisers check the actual notice and the exchange relief rules. Revenue Procedure 2018-58 has a separate section for these exchanges. Do not assume all filing relief extends every exchange date. A seller, intermediary, or broker cannot simply grant a federal extension. [5]
Use the time before your sale to learn what you may want to own next. You do not need a final list on the day you first call. You do need a clear sense of your income needs, debt, and plans for the money.
I would ask your team to build a rough closing estimate. How much cash is likely to enter the exchange? How much debt will be paid off? Which costs may change those figures? A small change in net cash can affect how you split the investment.
Next, decide who will collect each piece of the file. Someone should request the title work. Someone should check the loan terms. Someone should track the final notice. Write down the names instead of hoping each person thinks the other has it covered.
I also like to ask what would cause you to pass on a deal. A weak tenant, a long hold, or a large repair bill may be enough. Set those limits while you have time. Then use them when the deadline starts to feel close.
I would keep a short decision page beside the formal exchange documents. The decision page helps everyone see the same choices; it does not replace a signed identification.
For each investment, I would also write one sentence about why it belongs on the list and one about the main concern. This keeps a deadline discussion connected to the reasons you are investing.
Suppose two choices both meet your cash and debt needs. One has a tenant lease expiring soon; the other needs a large renovation. The identification form will not explain those tradeoffs. Your review notes should.
If the best available choices do not fit, compare that problem with the cost of recognizing some or all of the gain. The pressure to defer tax should not make every available property look acceptable.
No. Use calendar days under the ordinary rule. The period ends on the 45th day after the transfer, so weekends and holidays count. Plan earlier when a practical cutoff falls before that date; do not assume a weekend automatically moves the federal deadline.
You generally need to identify it within 45 days and receive it within the exchange period. You can buy during the identification period, and property received then is treated as identified. It also counts when applying the identification limits to your remaining choices.
Yes, when the applicable rules permit it. The 200% rule can allow more than three if their combined value stays within its limit. A list exceeding both main limits creates serious problems unless a specific exception applies. The 95% exception requires receiving nearly all the identified value.
No. The rule uses fair market values without subtracting secured debt. A $1 million property with $600,000 of debt does not become a $400,000 property for that test. Have advisers verify the relevant values, interests, and dates rather than use only the cash shown on a closing statement.
You can revise identifications before the period ends by following the required written procedures. Make sure any removed property is properly revoked. Under the ordinary rules, you cannot simply replace an unavailable choice with a new, previously unidentified property after the deadline.
No. Identification is a tax-exchange step, not a reservation guarantee. The offering sets its own process for accepting investors. Check the amount available, minimum, required documents, and funding schedule separately, and evaluate a suitable backup before the identification period ends.
No. Timing and identification are only part of the exchange. Property eligibility, ownership, funds, liabilities, expenses, and other rules still matter. Your CPA should calculate the result from the completed transaction. The examples here explain the deadline process and are not a ruling on a particular exchange.
Educational information, not an offer or a personal tax, legal, or investment recommendation. Examples are hypothetical and omit stated adjustments. Tax treatment depends on your facts and current law. Review your transaction with your CPA, attorney, and qualified intermediary. Real estate investments can lose value and may be illiquid.
