Free reminders for estimated tax dates
If you work for yourself, nobody withholds tax from your pay. We email you about 10 days before each usual federal estimated payment date: April 15, June 15, September 15 and January 15.

We email only after you confirm, and every email has an unsubscribe link. Dates move for weekends and holidays and your state may differ, so confirm on irs.gov. This is a reminder only. It is not tax advice and does not tell you what to pay.

- A reminder about 10 days before April 15
- A reminder about 10 days before June 15

Kestrel Tax
Doing your own Form 1040?
Kestrel Tax is a guided Form 1040 that runs on your own computer, for tax years 2025 and 2026, $39 one time. It lists the situations it does not handle and marks the return not complete instead of guessing. It does not e-file. The software is not a tax preparer, and this is not tax advice.
