About this app

Docket is a 1031 exchange deadline tracker for real estate investors. When you sell relinquished property in a 1031 like-kind exchange, two clocks start: 45 calendar days to identify replacement property, and 180 calendar days to close. Docket computes both deadlines from your closing date and counts down to each one, so you always know how much time is left.

Docket also applies the 1031 rule many investors miss. Your exchange must close by the earlier of the 180-day deadline or the due date, including extensions, of your federal tax return for the year of sale. For a late-year closing this can cut the window well below 180 days. Docket shows your effective closing deadline and flags when the cap applies.

A 1031 like-kind exchange lets real estate investors defer capital gains tax when they reinvest, but only when every deadline is met. Docket keeps those dates and documents in one place.

What Docket does:

Tracks the 45-day identification and 180-day exchange deadlines for each exchange, counted as calendar days with no weekend or holiday extension, matching IRS timing.

Works as a 1031 deadline calculator: enter your closing date and Docket computes the 45-day, 180-day, and effective deadlines at once.

Shows your effective closing deadline based on your federal return due date and whether you file an extension.

Tracks identified replacement properties against the three-property rule, the 200 percent rule, and the 95 percent rule.

Keeps a document checklist for each exchange, from the qualified intermediary agreement to the Form 8824 filing reminder.

Reminds you before each deadline with local notifications, fully offline.

Lets you record a disaster-extension override when a federally declared disaster relief period applies to your exchange.

Exports your exchanges as JSON or CSV for your own records.

Docket is built for real estate investors, agents, and anyone tracking a 1031 exchange timeline on their own.

Privacy: Docket works entirely on your device. There is no account, no cloud, no analytics, and no advertising. Your exchange data never leaves your phone unless you export it yourself.

Payment: the free version tracks one exchange with the full deadline timeline and checklist. A one-time Pro purchase unlocks unlimited exchanges, reminders, the identification-rule tracker, and export. There is no subscription in this app.

Docket tracks dates and documents you enter. It does not provide tax, legal, or investment advice, does not calculate taxes, and is not a substitute for a qualified intermediary or a professional advisor. Confirm every date with your qualified intermediary and tax advisor.
