The Big Picture—Deferring All Tax in a 1031 Exchange
Some taxpayers performing a 1031 exchange incorrectly assume that they are only required to invest their gain in order to defer all tax. This is an invalid assumption. Gain is defined as sales price minus closing costs minus the current adjusted tax basis. To defer all tax, the taxpayer must reinvest the net sales price minus closing costs, and replace all debt on the property. The adjusted tax basis is not included in this calculation.
Why it Matters
If a taxpayer receives anything of value from the sale of investment property (rather than reinvesting that amount), taxes will be due on those amounts received. In order to defer all tax in a 1031 exchange, the taxpayer must:
- Reinvest the entire net equity proceeds in one or more “like-kind” replacement properties, and;
- Incur the same or greater amount of debt that was extinguished on the sale. However, a taxpayer who does not want to incur debt to purchase the replacement property may replace the extinguished debt with additional cash.
Where Does “Boot” Fit In?
The term “boot” refers to any amount of value that the taxpayer elects to receive from the sale that is not reinvested. “Cash boot” refers to cash actually received and “mortgage boot” refers to any shortfall in debt replacement. Taxes may be owed on these amounts. To determine the taxes that may be due, the taxpayer’s tax advisor must first calculate the realized capital gain because this amount serves as a ceiling on taxes that will be owed. That is, the taxpayer will owe tax on the amount of the boot up to the amount of realized capital gain.
The Takeaway
Some taxpayers think that all they have to do to defer all tax is to reinvest their gain in replacement property. However, full deferral requires reinvestment of all equity and replacement of all debt.
