Meaning
Procedural actions maintain the right of a founder to be taxed on the value of restricted stock at the time of grant instead of the time of vesting. Filing the correct paperwork within thirty days of the stock purchase is the only way to achieve section 83b preservation and avoid higher future tax rates. Missing this deadline is often irreversible and leads to substantial financial costs.
Election Timeline
Mailing a physical letter to the tax authorities creates a permanent record of the election. This section 83b preservation is a one time opportunity that cannot be recovered if the window is missed. It is a binary event in the tax history of a founder.
Tax Efficiency
By locking in the value of the shares early, the holder ensures that all future growth is taxed as capital gains. Achieving section 83b preservation prevents a scenario where a founder owes large sums in taxes on stock that they cannot yet sell. The filing must be sent via certified mail with a return receipt to prove it arrived before the deadline.
Many law firms keep a copy of this receipt in the corporate minute book to reassure future investors. This step is an effective way to protect personal wealth during the early stages of a startup.
Vesting Rule
Without the election, the tax burden grows every time a new block of shares vests. This failure of section 83b preservation forces the holder to pay taxes on the market value at each anniversary.
