Both deadlines are calculated in calendar days, including weekends and holidays — there is generally no extension, except in specific IRS-declared disaster situations. The 180-day deadline can end sooner. Your exchange must close by Day 180 or by the due date of your tax return for the year you sold (including extensions), whichever comes first. This tool is for planning purposes only and doesn't replace confirmation from your Qualified Intermediary.
