Completing a 1031 exchange is only half the job. The other half is reporting it correctly on your federal tax return, and that reporting happens on a single, dense form: Form 8824, Like-Kind Exchanges. This form is where the IRS learns what you sold, what you bought, how much gain you realized, how much of that gain is currently taxable, and how your basis carries forward into your new property. Getting Form 8824 1031 exchange reporting right matters not just for this year’s return, but for every future depreciation schedule and eventual sale of the replacement property.
Before your CPA sits down to prepare this form, make sure your exchange documentation is complete. Talk with Aspen Exchange early in the process so the records your accountant needs are gathered as you go, not reconstructed months later.
What Form 8824 Is Asking For
Form 8824 is organized into four parts, and while the language is technical, the underlying questions are fairly logical once you walk through them in order.
Part I: Information About the Like-Kind Exchange
This section asks for basic descriptions of both the property you gave up and the property you received, including the type or use of each property and the dates involved. Specifically, it asks for the date the relinquished property was originally acquired, the date it was transferred (sold) as part of the exchange, the date the replacement property was identified in writing, and the date the replacement property was received. These dates matter because they are what the IRS uses to confirm your exchange met the 45-day identification window and the 180-day completion window described in the complete guide to 1031 exchange rules. This part also asks whether the exchange involved a related party, which connects to a more detailed related-party question later in the form.
Part II: Related Party Exchanges
If your relinquished or replacement property was exchanged with a related party, such as a family member or a business entity you control, this section asks additional questions designed to confirm that both parties held onto their respective properties for the required period and that the exchange was not structured primarily to shift basis or cash out tax-free. Related-party exchanges carry extra scrutiny, and the details covered here are worth reviewing closely with your CPA if this applies to your transaction.
Part III: Realized Gain or Loss, Recognized Gain, and Basis of Replacement Property
This is the heart of the form, and it is where the actual math happens. Part III walks through a series of calculations, generally including:
- Fair market value of the like-kind property received and any other property or money received as part of the exchange
- Adjusted basis of the property given up, along with exchange expenses
- Realized gain, which is the total economic gain on the transaction before considering how much of it is deferred
- Boot received, meaning cash or non-like-kind property that reduces the amount of gain eligible for deferral, a concept explored further in the guide to how 1031 exchange boot creates an unexpected tax bill
- Recognized gain, which is the portion of the realized gain that is currently taxable, generally limited to the amount of boot received
- Basis of the replacement property, which carries forward your original investment basis, adjusted for any gain recognized, boot received, and exchange costs
That last line item, the basis of the replacement property, is arguably the most consequential number on the entire form, even though it often gets the least attention from investors focused on this year’s tax bill.
Part IV: Deferral of Gain From Section 1031 Like-Kind Exchanges Under the Related Party Rules
This section applies to certain conservation and related-party situations and does not come into play for most straightforward investor exchanges, but your CPA will confirm whether it applies to your specific transaction.
Why Basis Carryover Deserves Extra Attention
It is easy to treat Form 8824 as a one-time filing exercise: complete it, attach it to your return, move on. But the basis figure calculated in Part III does not disappear after this year’s return is filed. It becomes the starting point for depreciating your replacement property going forward, and it becomes the number your CPA will use to calculate gain when you eventually sell that property, whether in another exchange or in a fully taxable sale.
An error in this calculation, even a modest one, can compound over years of depreciation deductions and then resurface as a much larger problem when the replacement property is eventually sold and the IRS or your own records show a mismatch. This is one of the clearest reasons why 1031 exchange depreciation recapture, covered in detail in our guide to depreciation recapture in a 1031 exchange, is so closely tied to accurate Form 8824 preparation in the first place.
Why This Form Should Be Prepared by a CPA, Not Self-Filed Software
Consumer tax software can walk a filer through many common tax situations reasonably well, but Form 8824 is one of the areas where that general-purpose approach tends to break down. A few reasons this form benefits from professional preparation:
- The realized gain, recognized gain, and basis calculations depend on precise figures from your closing statements, your exchange agreement, and your qualified intermediary’s records, and small input errors can meaningfully change the outcome.
- Multi-property exchanges, where several relinquished or replacement properties are involved, require careful allocation of basis and gain across each property, which off-the-shelf software is not always built to handle cleanly.
- Related-party exchanges add an additional layer of questions and reporting obligations that require judgment about your specific facts.
- Because the replacement property basis affects future depreciation and future sales, an error compounds over time rather than resolving itself, and is much more expensive to fix years later than it would have been to prevent up front.
A CPA experienced with exchange transactions can also cross-check your Form 8824 figures against your 1099-S forms and closing statements, an exercise covered in more depth in our discussion of 1031 exchange 1099 reporting, to make sure everything ties out before the return is filed.
Documents Your CPA Will Need
- Closing or settlement statements for the relinquished and replacement properties
- The exchange agreement and assignment documents from your qualified intermediary
- Your written 45-day identification notice
- Records of any cash, debt relief, or other boot received during the exchange
- Prior depreciation schedules for the relinquished property
- Any 1099-S forms issued in connection with the transaction
What Happens If the Exchange Spans Two Tax Years
Because the 180-day completion window can carry an exchange from one calendar year into the next, it is common for an investor to sell a relinquished property in, say, November and not close on the replacement property until the following spring. Form 8824 is generally filed with the return for the year in which the relinquished property was transferred, even if the replacement property has not yet closed by the original filing deadline. In these situations, taxpayers sometimes need to file an extension so that the exchange has time to complete before the return is finalized, rather than filing early and later needing to amend. Your CPA can advise on whether an extension makes sense given your specific closing timeline, and can also advise on the rare situations where an amended Form 8824 becomes necessary, such as when a replacement property identified within the 45-day window is ultimately not acquired and the exchange partially or fully fails.
Frequently Asked Questions
Do I have to file Form 8824 every year I own the replacement property?
No. Form 8824 is generally filed for the tax year in which the exchange transaction occurred. After that, the calculated basis simply carries forward into your regular depreciation schedule for the replacement property.
What is the difference between realized gain and recognized gain on Form 8824?
Realized gain is the total economic gain on the transaction. Recognized gain is the portion of that gain that is currently taxable, which in a properly structured exchange is generally limited to any boot received rather than the full realized gain.
What happens if I make a mistake on Form 8824?
An error can affect your current year’s tax liability and can also distort your replacement property’s basis, which impacts future depreciation and gain calculations for years to come. If you discover an error, work with your CPA on how best to correct it, which may involve an amended return.
Can tax preparation software handle Form 8824 on its own?
Basic software may handle simple, single-property exchanges reasonably well, but multi-property exchanges, related-party transactions, and situations involving boot generally benefit from review by a CPA experienced with exchange transactions.
Does my qualified intermediary file Form 8824 for me?
No. Your qualified intermediary facilitates the exchange itself and provides documentation, but Form 8824 is prepared and filed by you, typically with the help of your CPA, as part of your income tax return.
