IRC §83: Property Transferred for Services

By Paul D. Diaz, EA, MBA · Updated

IRC §83 taxes equity pay at vesting — fair market value minus what you paid — unless an 83(b) election moves the tax to grant day. Thirty days to file it; no extensions, no mercy.

Questions this section answers

Should I file an 83(b) election?
When the grant-day value is low and growth looks likely: pay a little ordinary income now so all appreciation becomes capital gain. Startup founders with penny-value stock are the classic yes; the 30-day deadline is absolute.
Can I make an 83(b) on RSUs?
No — RSUs are unfunded promises, not transferred property, so no election exists. They tax as ordinary income at vesting on the full value. Founders get 83(b); RSU holders get withholding.
What if I miss the 30-day 83(b) window?
It’s gone — the statute allows no extensions and the IRS grants no relief. The stock taxes at each vesting date on its then-value. File on day one, certified mail, keep the receipt forever.
