83(b) election guide: deadline, how to file, and when it makes sense

An 83(b) election tells the IRS you want to be taxed on restricted stock when you receive it, rather than each time it vests. You must file it within 30 days of the stock being transferred to you, with no extensions. For founders buying shares at fair market value, the tax owed at filing is usually zero, and filing avoids ordinary income tax on the stock's growth as it vests. Since July 2025 you can file online with IRS Form 15620.
