A 1031 exchange is a swap of one business or investment asset for another. Although most swaps are taxable as sales, if you come within 1031, you’ll either have no tax or limited tax due at the time of the exchange.
In effect, you can change the form of your investment without (as the IRS sees it) cashing out or recognizing a capital gain. That allows your investment to continue to grow tax deferred. There’s no limit on how many times or how frequently you can do a 1031. You can roll over the gain from one piece of investment real estate to another to another and another. Although you may have a profit on each swap, you avoid tax until you actually sell for cash many years later. Then you’ll hopefully pay only one tax, and that at a long-term capital gain rate .
