What Happens to Passive Losses in a 1031 Exchange?

When a real estate investor executes a 1031 exchange for a property with accumulated suspended passive losses, specific tax regulations come into play that diverge from a standard taxable sale. The tax-deferred nature of a 1031 exchange fundamentally changes how these losses are treated, preventing their immediate use and creating a distinct set of rules for their future application.

The Foundation of Passive Activity Loss Rules

The Internal Revenue Code establishes that rental real estate is generally considered a passive activity. This classification applies unless the owner qualifies as a “real estate professional,” a specific designation requiring significant time investment in real property trades or businesses, typically more than 750 hours annually. For most other investors, any rental property they own is a passive activity, meaning the income or losses generated are subject to particular limitations.

Passive losses are created when the deductible expenses of a rental property, such as mortgage interest, property taxes, and depreciation, exceed the rental income for a given year. Under the passive activity loss (PAL) rules found in Section 469 of the tax code, these losses cannot be used to offset other types of income, like wages from a job or portfolio income. Instead, they become “suspended” and are carried forward to be used against passive income in future years.

The standard treatment of these losses changes significantly upon a property’s sale. When an investor disposes of their entire interest in a passive activity through a fully taxable transaction to an unrelated party, all suspended passive losses associated with that specific activity are released. This release allows the losses to be deducted against any category of income in the year of the sale.

How a 1031 Exchange Alters Loss Treatment

In a 1031 exchange, the standard rule for releasing suspended passive losses does not apply. This is a direct consequence of the exchange’s tax-deferred status under Section 1031 of the Internal Revenue Code, as the IRS does not view it as a complete disposition of the investment. The underlying principle is that the investor has continued their investment in a similar, or “like-kind,” property.

Because the transaction is considered a continuation, the tax consequences, including both gains and the release of losses, are postponed. The logic is that since the capital gain is not being recognized, the associated suspended losses should not be recognized either. Instead of being released, the suspended passive losses from the relinquished property carry over to the new replacement property, maintaining their passive character.

The Role of Boot in Releasing Losses

The deferral of gains and the carryover of losses in a 1031 exchange can be partial. This occurs when an investor receives “boot,” which is any property received in the exchange that is not of like-kind to the property being sold. Boot most commonly takes the form of cash, but it can also include relief from debt or personal property that is part of the transaction.

When an investor receives boot, the 1031 exchange is no longer fully tax-deferred. The investor must recognize a taxable gain, but only up to the amount of the boot received. For example, if an investor has a total realized gain of $100,000 but receives $20,000 in cash boot, they are only required to pay taxes on that $20,000 of gain. The remaining $80,000 of gain remains deferred.

This is where suspended passive losses can be utilized. The tax code permits an investor to use their suspended PALs to offset the taxable gain triggered by the receipt of boot. If an investor has $30,000 in suspended losses and recognizes a $20,000 gain from boot, they can use $20,000 of their losses to completely offset that gain. This results in no immediate tax liability, and the remaining $10,000 of suspended losses would then carry over to the replacement property.

Managing and Deducting Losses After the Exchange

Any suspended passive losses that were not used to offset boot are carried over and attached to the replacement property. During the holding period of the new property, these carried-over losses can be deducted against any passive income it generates. For instance, if the replacement property generates $10,000 in net rental income and the investor has $40,000 in suspended losses, they can use $10,000 of those losses to reduce the taxable income to zero.

The remaining $30,000 in losses would then be carried forward to the next year. If the new property also generates losses, these new losses are added to the existing suspended loss balance. The ultimate release of all remaining suspended losses occurs when the replacement property is eventually sold in a fully taxable transaction.

At that point, the entire accumulated amount—both the original losses from the first property and any new losses from the replacement property—can be deducted against any type of income in the year of the sale. In situations where an exchange involves acquiring multiple replacement properties, the suspended losses from the original property must be allocated between them. This allocation is typically done in proportion to the fair market value of each new property, and as each is sold, the allocated portion of losses is released.
