Day 45
Day 180
Identification Deadline
The last day to deliver your written identification of potential replacement properties to your Qualified Intermediary.
Exchange Deadline
The last day to close on the replacement property you identified, completing your 1031 exchange.
Exchange Deadlines
There are two key deadlines that the Exchanger must meet to have a valid exchange.
Identification Period
Within 45 calendar days of the transfer of the first Relinquished Property, the Exchanger must identify the Replacement Property to be acquired.
Exchange Period
The Exchanger must receive the Replacement Property within the earlier of 180 calendar days after the date on which the Exchanger transferred the first Relinquished Property, or the due date (including extensions) for the Exchanger’s tax return for the tax year in which the transfer of the first Relinquished Property occurs.
Strict Time Periods
The time periods for the 45-day Identification Period and the 180-day Exchange Period are very strict and cannot be extended even if the 45th day or 180th day falls on a Saturday, Sunday or legal holiday. They may, however, be extended by up to 120 days if the Exchanger qualifies for a disaster extension under Rev. Proc. 2007-56.
