While foreign property is not of a like kind with domestic property, foreign properties are considered like-kind with one another. You can perform a 1031 exchange with foreign properties, so long as your relinquished and replacement properties are both located outside the United States.
A 1031 Exchange allows for the deferral of capital gains tax by replacing property with one of like-kind and equal or greater value. This exchange operates within a strict timeline, requiring identification of potential replacement properties within 45 days and completion of the exchange within 180 days.
This means that you cannot perform a 1031 exchange between a U.S. property and a non-U.S. property. If your relinquished property is located within the United States, then your replacement property must also be located within the United States (or certain U.S. territories) to qualify for 1031 tax deferral.
