How do I file an 83(b) election?

To file an 83(b) election, complete IRS Form 15620 (or a written statement containing the same information) within 30 days of your stock grant date.

This deadline is absolute and cannot be extended. You can now file electronically through your IRS Online Account, or mail the form to the IRS Service Center where you file your tax return. The form must include: your name and address, your SSN, a description of the property (shares), the date transferred, the fair market value on the grant date, the amount you paid, and a statement that you are making the election under Section 83(b). Keep a copy for your records and attach another copy to your tax return for that year. Lovie's formation flow prompts founders to file their 83(b) election immediately after share issuance.
