A valid 1031 identification has to be in writing, describe the replacement property unambiguously by street address or legal description, be signed by the taxpayer, and reach the qualified intermediary before midnight on Day 45. The advisor's job is to check it against the purchase agreement, confirm the entity name matches, verify it went to the QI rather than a disqualified party, and preserve proof of timely delivery.
A 1031 exchange comes down to one document and one deadline. Within 45 days of selling the relinquished property, the taxpayer has to name in writing what they intend to buy, and once midnight on Day 45 passes, that list is final. A description too vague for a stranger to act on, a signature from someone without authority, or a letter sent to the accountant instead of the qualified intermediary that holds the sale proceeds: any one of these can turn a planned exchange into a costly failure.
Identification Letter Template
The template covers every field a valid identification needs. Fill in the brackets, then check each entry against the source documents before it goes out.
IDENTIFICATION OF REPLACEMENT PROPERTY IN 1031 EXCHANGE
Date: [Today's date]
Taxpayer: [Legal entity name, e.g., "ABC Investment LLC, a [State] limited liability company"]
Exchange Reference Number (if applicable): [QI exchange ID or transaction reference]
Qualified Intermediary: [QI name and address]
Relinquished Property: [Street address or legal description of sold property]
Date of Sale: [Closing date of relinquished property]
Instructions to Qualified Intermediary:
Pursuant to Treasury Regulation Section 1.1031(k)-1(c), the undersigned taxpayer identifies the following replacement property for the above-referenced 1031 exchange:
Replacement Property Identification:
Property 1:
- Address: [Street address]
- Legal Description: [Full legal description as it appears in the deed or purchase agreement]
- County and State: [Location]
- Expected Closing Date: [If known]
Property 2: [Repeat as needed]
Property 3: [Repeat as needed]
Certification:
I/We certify that the above property or properties are identified in good faith and with the intention to acquire them in exchange for the relinquished property. I/We understand that this identification is binding and that no changes may be made after midnight on [Day 45 date, Year].
Signature:
**______**___ [Taxpayer name and title, if entity]
Date: **____**_
Delivery Confirmation:
This identification was delivered to the Qualified Intermediary via [email/hand-delivery/fax] on [date] at [time].
Confirmation receipt: [receipt number or email confirmation]
How to Complete the Template
Entity Name: Use the taxpayer entity's exact legal name. Include the state of formation for an LLC and "Inc." or "Corp." for a corporation. Do not use an individual's trade name if they operate through an entity.
QI Information: Use the qualified intermediary's full name and the address the identification is being sent to, and confirm that address before sending.
Relinquished Property Description: Use the exact address and legal description from the deed. It has to match the sale closing documents.
Replacement Property Description: Use the street address and full legal description from the purchase agreement. For newly constructed property, use the lot and block number from the recorded plat. Copy the legal description straight from the purchase agreement or preliminary title report rather than paraphrasing or working from memory.
Expected Closing Date: Optional, and only planning information. If the date changes, the identification still stands.
Signature: The taxpayer signs. For an entity, find the proper signatory in the operating agreement or bylaws; if there is any doubt, include a board resolution or member approval that authorizes the exchange and names the signatory.
Delivery Confirmation: Record how it was delivered and the exact date and time.
Advisor Review Checklist
Before the taxpayer submits the identification to the QI, verify each item.
Legal Requirements for a Valid Identification
A valid identification has to clear four tests.
Requirement | Standard | Common Failure |
|---|---|---|
In writing | Written document (email or fax acceptable; verbal is not) | Client assumes a phone call to the QI is sufficient |
Unambiguous | Property described so precisely that a third party could identify it with certainty; street address is the minimum, legal description is preferred | "A commercial property in Phoenix" or "the office building on Central Avenue" |
Signed by taxpayer | The taxpayer entity (not an agent) must sign; for an LLC, determine proper signatory authority | Agent or advisor signs without taxpayer authorization |
Delivered to non-disqualified party | Must be delivered to the QI, escrow agent, or title company holding funds; delivery to the taxpayer's attorney or accountant does not satisfy the requirement | Identification sent to CPA instead of QI |
The Three Identification Rules
Rule | How Many Properties | Value Limit | Closing Requirement |
|---|---|---|---|
3-Property Rule | Up to 3 | No value limit | Must close on at least 1 |
200% Rule | Any number | Aggregate value cannot exceed 200% of relinquished property value | Must close on at least 1 |
95% Rule | Any number | Aggregate value cannot exceed 95% of relinquished property value | Must close on at least 95% of identified value |
Only one rule governs a given exchange. Identify three or fewer properties and the 3-property rule applies; identify four or more and the 200% or 95% rule applies, based on aggregate value. If a taxpayer identifies three properties and one falls through, they cannot add a fourth after Day 45.
Common Mistakes and Fixes
Mistake | Why It Fails | Fix |
|---|---|---|
Vague property description | "A commercial property in Phoenix" is not unambiguous; a third party cannot identify the specific property | Use street address and full legal description from the purchase agreement |
Wrong entity name | "Smith Investments" instead of "ABC Investment LLC" creates ambiguity about who the taxpayer is | Use the exact legal entity name as it appears on the exchange documents |
Inconsistency with purchase agreement | "Lot 3, Block A" vs. "Lot 3, Block 1" creates doubt about whether the identification matches | Copy legal description directly from the purchase agreement and title report |
Identifying the wrong property | Client closes on a different property than the one identified | Do not identify a property unless the taxpayer is confident they will close on it |
Delivering to a disqualified person | Sent to CPA or real estate agent instead of QI | Confirm QI address and deliver directly to them |
Miscounting Day 45 | Day 1 is the day after closing; counting error causes late submission | Use a deadline calculator; have the QI confirm the deadline in writing |
Including personal property | "All machinery and equipment on the property" complicates the 1031 analysis | Identify only the real property; separate exchanges for equipment are subject to different rules |
Multi-Property Identifications and the 95% Rule
The 95% rule splits its test across two dates:
- At identification (Day 45): the aggregate value of identified properties must not exceed 95% of the relinquished property value.
- At closing (Day 180): the taxpayer must actually close on properties totaling at least 95% of the identified value.
That second obligation is where the risk lives. If the taxpayer identifies properties speculatively, or market conditions change before closing, falling short of the 95% threshold voids the exchange. Counsel taxpayers carefully on the closing obligation.
Delivery and Documentation
Email delivery creates a time-stamped record, which makes it easy to prove when the identification went out. A subject line like "1031 Exchange - Identification of Replacement Property - [Taxpayer Name]" keeps it findable.
Ask for a read receipt or written confirmation from the QI, and preserve it. In an audit, proof of timely delivery is critical. The strongest version is a written confirmation of receipt from the QI within 24 hours; if the QI does not issue one automatically, request it in writing.
Extension of the Identification Deadline
The identification deadline can be extended only in narrow circumstances under Rev. Proc. 2005-14, such as a natural disaster, the death of a key person, or war. Extensions are rare and require a showing of extraordinary circumstances. Do not plan on an extension; plan on the original deadline.
Bottom Line
The identification letter is the moment the exchange either holds or fails. Draft it from this template, verify it against the source documents, run the review checklist, confirm delivery to the QI, and record the delivery time. That attention is what separates a successful exchange from a costly failure.
Identification is non-negotiable and the deadline is effectively fixed. Use a template, review it carefully against the source documents, and document delivery before Day 45 ends.
Frequently asked questions
Can you change or revoke identifications after Day 45?
No. Once midnight on Day 45 passes, every identification is locked and the taxpayer is limited to what they named by the deadline. There is no fresh identification period afterward. If an identification turns out to be invalid, for example because the property never closes, the exchange is lost unless the taxpayer can show reasonable cause for the failure.
Can you identify a property that hasn't been built yet?
Yes, as long as the description is unambiguous, such as "Lot 5, Block 2, recorded as Document XYZ in County Records." The catch is timing: construction has to be complete by the end of the 180-day exchange period, or the exchange fails for that property. Flag this risk early and confirm the construction timeline with the developer.
Can you identify more than 3 properties under any rule?
Yes, under two of the three rules. The 3-property rule caps you at three, with no value limit. The 200% rule lets you identify any number of properties as long as their combined value stays within 200% of the relinquished property value. The 95% rule also allows any number, capped at 95% of the relinquished value, but it requires you to close on at least 95% of the value you identified. So more than three is permitted only when you accept the value limit and, under the 95% rule, the closing obligation.
What happens if the identification letter has a typo in the address?
It depends on whether the typo still lets someone identify the intended property. If it does not, the identification is invalid. Even a small slip, such as "123 Maple Street" instead of "125 Maple Street," can be fatal if it creates confusion, which is why full legal descriptions and street addresses from the purchase agreement matter. Catch a typo before midnight on Day 45 and you can issue a corrected identification; after Day 45 you cannot.
Should the advisor review the identification letter before submission?
Yes. Review it for clarity, consistency with the purchase agreement, the correct entity name, and timely delivery to the QI. One safeguard is to have the client send the draft identification to the advisor before it goes to the QI, so errors surface while there is still time to fix them.
