45/180-Day Deadline Calculator
Enter your relinquished close date for the exact 45-day identification and 180-day completion deadlines, with the days remaining on each clock.
How this is calculated
Both clocks start the day after the relinquished property closes. You have 45 calendar days to identify replacement property in writing, and 180 calendar days to close on it.
The IRS counts calendar days. Weekends and holidays do not extend either deadline. The 180-day clock can be shortened by your tax-return due date, so confirm with your qualified intermediary.
Track these deadlines in your Shop 1031 dashboard.
