Practical Example

A land broker in Texas sells a 200-acre ranch on March 1, 2026 for $1.2M. Using this calculator, they instantly see:

  • 45-Day Deadline (April 15, 2026): Must identify replacement properties in writing to their QI by this date.
  • 180-Day Deadline (August 28, 2026): Must close on the replacement property by this date.

The broker uses these dates to coordinate with their QI, title company, and buyer's agent — ensuring no deadline is missed and the tax deferral stays intact.

45-Day Rule

You have exactly 45 calendar days from the sale of your relinquished property to identify potential replacement properties in writing.

180-Day Rule

You must close on the replacement property within 180 calendar days of the sale, or by your tax return due date — whichever comes first.

3-Property Rule

You may identify up to three properties as potential replacements regardless of their value, or more under the 200% or 95% rules.
