Timeline reminders
45 days from sale closing to identify replacement property in writing to your Qualified Intermediary. 180 days total (including the 45) to close on one identified property. Miss either and the exchange fails — pay full tax.
Not tax or legal advice.
Structuring a 1031 exchange requires a Qualified Intermediary and often a tax attorney. Mistakes — including touching proceeds personally, missing deadlines, or receiving unexpected boot — can trigger full tax liability plus penalties. Always consult a 1031-specific CPA and QI before closing.
