For a deferred exchange to qualify under Internal Revenue Code 1031, it must meet the two time requirements in Internal Revenue Code 1031:

• The replacement property must be identified within 45 days after the relinquished property is transferred; and
• The replacement property must actually be received on or before the earlier of (1) 180 days after the date the relinquished property is transferred, or (2) the due date of the transferor's tax return for the taxable year in which the relinquished property is transferred, taking into account any extra time allowed by authorized extensions to file the return.

Notice:
The actual deadline for completing an exchange is the earlier of either 180 days from the date on which the Exchangor transfers the relinquished property, or the due date, including extensions filed by the Exchangor, for the Exchangor's tax return for the year of the transfer of the relinquished property. Consult your tax advisor regarding your tax filing requirement dates.
