What Is Boot in a 1031 Exchange

Boot is any value received by an investor in a 1031 exchange that is not like kind replacement real property. Boot does not disqualify an exchange, but it is taxable in the year the exchange closes, to the extent of the investor's realized gain. Understanding boot matters because many investors assume an exchange is either fully tax deferred or fully taxable, when in practice most exchanges fall somewhere in between, with a portion of the gain deferred and a portion recognized as boot.

Boot takes several common forms. Cash boot occurs when an investor receives cash proceeds from the exchange rather than reinvesting the full amount into replacement property. Mortgage boot, also called debt relief boot, occurs when the debt paid off on the relinquished property exceeds the debt placed on the replacement property, unless that reduction is offset by adding new cash to the deal. Personal property boot can occur when a small amount of tangible personal property, such as furniture or equipment, is transferred along with real property, though this is less common in exchanges involving commercial real estate.

The most frequent source of boot in Charlotte, NC exchanges is a mismatch between the value or debt level of the relinquished property and the replacement property. To fully defer gain, an investor generally needs to acquire replacement property of equal or greater value, using all of the net exchange proceeds, and replace any debt paid off on the relinquished property with equal or greater debt on the replacement property, or with additional cash. If the replacement property has a lower purchase price or a smaller loan balance, the difference is typically treated as boot and becomes taxable.

Boot is taxed as capital gain to the extent of the investor's realized gain in the exchange, and depreciation recapture rules can also apply to the extent the boot represents previously claimed depreciation. Because these calculations depend on the investor's basis, holding period, and depreciation history, boot exposure should be reviewed with a tax advisor before a replacement property is selected, not after the exchange has already closed. Investors in Charlotte, NC who want to fully defer gain typically work with their qualified intermediary and tax advisor early in the process to model out debt and equity levels across candidate replacement properties, so that boot exposure is understood before an offer is made rather than discovered at tax time.
