In a 1031 exchange, boot is taxable in the year the exchange is completed. Boot refers to any non-like-kind property or cash received in the exchange, which is subject to capital gains tax. The taxable boot can arise from cash not reinvested, debt relief, or other non-like-kind property received during the exchange.

To illustrate this, let's consider an example where Deferred.com acts as your Qualified Intermediary (QI). Suppose you own a commercial property with a fair market value of $500,000 and a mortgage of $300,000. You decide to exchange this property for another commercial property worth $450,000, with a mortgage of $250,000.

Here's how the exchange might unfold:

1. Sale of Relinquished Property: You sell your original property for $500,000. After paying off the $300,000 mortgage, you have $200,000 in cash proceeds. These proceeds are held by us, Deferred.com, as your QI.
2. Purchase of Replacement Property: You purchase a replacement property for $450,000. You use the $200,000 cash proceeds as a down payment and take out a new mortgage for $250,000.
3. Calculation of Boot:
   • Cash Boot: Since the replacement property costs $450,000, and you reinvested the full $200,000 cash proceeds, there is no cash boot.
   • Mortgage Boot: The original mortgage was $300,000, and the new mortgage is $250,000. The $50,000 difference is considered mortgage boot, as you are relieved of more debt than you take on.

In this scenario, the $50,000 mortgage boot is taxable in the year the exchange is completed. This is because the boot represents a gain realized from the exchange, and under Section 1031(b), gain is recognized to the extent of the boot received.

It's important to note that the timing of the exchange completion is crucial. The exchange must be completed within 180 days of the sale of the relinquished property or by the due date of your tax return for the year in which the relinquished property was sold, whichever comes first. The boot is reported on your tax return for that year.

At Deferred.com, we ensure that all proceeds are handled correctly and that the exchange is structured to minimize or eliminate boot, helping you defer as much taxable gain as possible. If you have any further questions or need assistance with your 1031 exchange, feel free to reach out to us.
