1031 exchange calculators

Three calculators for the questions that come up before every sale. Each one states its assumptions on the page. They run in your browser, and nothing you enter is sent to onezero3one.

The results are estimates for orientation, not tax advice. Your tax advisor confirms the figures, and the exchange agreement fixes the dates, for your own exchange.

Guides

Plain-language explanations of the rules that govern an exchange, from the two deadlines to what happens when an exchange fails. See all guides.

The 1031 exchange checklist lists every step in three stages, with who is responsible for each. It prints on a few pages and needs no email.

When there is a sale in view, tell us where it stands. Using the calculators never requires it.
