Boot is the term the IRS uses for anything of value an investor receives out of a 1031 exchange that is not like-kind replacement real estate, and it is the single most common way an otherwise well-structured exchange still generates a tax bill. A Memphis investor can defer gain completely and still owe tax on a slice of it, simply because the numbers on the two sides of the trade did not line up exactly.
Cash Boot Is The Easiest Kind To Spot
Cash boot happens whenever the investor walks away from the exchange holding money instead of putting every dollar of net proceeds into the replacement property. Buying a replacement that costs less than the relinquished property sold for, and pocketing the difference, is the clearest version, but cash boot can also show up in smaller ways, such as leftover funds sitting with the qualified intermediary after closing that never get reinvested. Any dollar the investor receives, rather than reinvests, is taxed as gain up to the amount of that boot.
Mortgage Boot Comes From The Debt Side
Mortgage boot, sometimes called debt-relief boot, is less intuitive because no cash actually changes hands with the investor directly. It occurs when the debt paid off on the relinquished property is larger than the debt taken on for the replacement property, which the IRS treats as if the investor received the difference in cash even though it only shows up on the settlement statement. An investor selling a Shelby County property with a $900,000 mortgage and buying a replacement with only $650,000 in new debt has created $250,000 of mortgage boot, regardless of how the cash proceeds were otherwise reinvested.
Why Equal Or Greater Value And Debt Both Matter
Avoiding boot generally requires the replacement property to be equal to or greater in value than the relinquished property, and the new debt to be equal to or greater than the debt that was paid off, unless the investor covers the debt gap with additional cash. It is possible to offset mortgage boot with extra cash brought to closing, but cash cannot offset mortgage boot in the other direction, and investors sometimes assume the two sides of the ledger net out more freely than the IRS actually allows.
Where Memphis Investors Run Into Boot Unexpectedly
Boot tends to surface in exchanges where an investor deliberately trades down, such as moving out of a larger East Memphis office holding into a smaller, lower-maintenance retail property near Collierville or Germantown, often to reduce management burden heading into retirement. That kind of trade-down is a completely legitimate goal, but it should be modeled against boot exposure before the sale closes, not discovered on the settlement statement afterward. Closing costs and prorations paid from exchange funds can also create small, easy-to-miss boot if they cover items the IRS does not treat as eligible exchange expenses.
Running The Numbers Before The Sale, Not After
A rough boot estimate is worth building before the relinquished property ever goes under contract, since it changes what an investor is willing to accept in a replacement offer. Comparing expected net sale proceeds and payoff debt against the price range and likely financing on candidate replacement properties, even loosely, tells an investor whether a given deal is likely to be boot-free or whether it is going to create a taxable slice worth planning around. Because Tennessee has no state income tax, the boot exposure on a Memphis-area sale is purely federal, but that federal exposure, layered with depreciation recapture on a long-held property, can still be a meaningful number when it lands on the wrong side of the calculation.
Common 1031 Exchange Questions
Is all boot taxed at the same rate as the rest of my gain?
Boot is taxed as gain up to the amount of the boot received, using the same capital gains and depreciation recapture rules that would have applied to that portion of the sale outside an exchange.
Can I use exchange funds to pay off other debt without creating boot?
Generally no. Using exchange funds for anything other than acquiring the replacement property, including paying off unrelated debt, typically creates boot or disqualifies those funds from the exchange.
Does trading into a lower-priced property always create boot?
It creates boot on the value difference unless the investor also reduces the new debt proportionally and does not walk away with cash. Trading down in value is allowed, it simply means paying tax on the portion that is not reinvested.
Can extra cash at closing offset mortgage boot?
Yes. Bringing additional cash to the replacement closing can offset a debt shortfall and avoid mortgage boot, but the reverse is not true, extra debt cannot offset cash boot.
Who calculates whether an exchange has boot exposure?
The qualified intermediary tracks the exchange funds, but the boot calculation itself is usually run by the investor's exchange advisor or CPA, comparing relinquished and replacement values and debt before the replacement closing is finalized.
