What is the federal deadline for an 83(b) election?

File it no later than 30 days after the property transfer.

  1. By the next April 15
  2. Within 30 days after transfer ✔
  3. Within one year after vesting

Why: The 30-day clock starts when the property is transferred, not when it later vests. Missing this short deadline can change the tax timing.

Huh, didn't know that: If day 30 falls on a weekend or legal holiday, a postmark on the next business day counts as on time.

The dad joke
The 83(b) form joined a sprint because thirty days goes fast.
