1031 Exchange Tracker

Docket

Track every 45 and 180 day exchange deadline offline.

About

Docket tracks the deadlines that decide whether a 1031 like-kind exchange succeeds. When you sell relinquished property, two clocks start: 45 calendar days to identify replacement property, and 180 calendar days to close. Docket computes both from your closing date, applies the tax-return-due-date cap that shortens the window for late-year closings, and counts down to each date with color-coded urgency. The free tier tracks one exchange with the full timeline, the effective-deadline cap, an editable document checklist, and one 7-day reminder per deadline. A one-time $14.99 Pro unlock adds unlimited exchanges, custom and multiple reminders, the replacement-property identification tracker (three-property, 200 percent, and 95 percent rules), and JSON / CSV export and import. Everything runs on the device: no account, no cloud, no ads, and the Pro unlock is a one-time purchase, not a subscription.

Accuracy and limitations

Docket tracks the dates and documents you enter. It does not provide tax, legal, or investment advice, does not calculate taxes, gain, or basis, and is not a substitute for a qualified intermediary or a professional advisor. The 45-day and 180-day periods are counted as calendar days from the day after the relinquished transfer, with no weekend or holiday extension, matching IRS timing; the effective deadline is the earlier of the 180-day date and your federal return due date (including extensions), which you enter. Confirm every date with your qualified intermediary and tax advisor.
