Your 83(b) deadline

Enter the day that the company issued your shares to you. The election is due 30 days later.

You got the shares on Wednesday, November 4, 2026. Day 30 is Friday, December 4, 2026. File online or mail the form with a postmark by that day. A legal holiday on day 30 moves the deadline later, so this date is always safe.

Do not wait for the last day. File in the first week, and keep your proof of the filing.

If day 30 is a legal holiday, the deadline also moves to the next business day. This calculator moves the date only for weekends, so it never shows a date that is too late.
