What is boot?

Boot is any value you receive in an exchange that you do not reinvest — and it is taxable even inside a 1031 exchange. There are two kinds:

How to defer the entire gain

To eliminate boot, replace both your equity and your debt: reinvest all of your net equity and take on at least as much new debt as you paid off — or add equal cash to offset a smaller loan. Acquire replacement property of equal or greater value, and the full gain can be deferred.

Results depend on your inputs and assumptions and will differ from actual outcomes; a 1031, 721, or Opportunity Zone transaction may fail to qualify for the intended tax deferral.
