83b election

Fiscal Impact

Upfront payment of taxes prevents future levies on the increased value of the equity as it matures. An 83b election converts potential ordinary income into capital gains which are usually taxed at a lower rate. The trade off involves paying cash today for a future benefit that remains uncertain.

This choice effectively stops the tax clock on the appreciation of the shares.

Chronological Constraint

Filing must happen within a strict thirty day window following the acquisition of the shares. Missing this deadline for an 83b election is generally irreversible and leads to tax obligations on the full value of every future vesting event. Verification of receipt by the tax office is the only way to prove compliance.

Capital Exposure

Cash used to pay the tax is lost if the company fails or the individual leaves before their shares are earned. The holder of an 83b election accepts the risk of overpaying for assets that might lose all value. This commitment requires the person to divert personal savings into a tax prepayment.

Success depends on the eventual liquidity of the shares being greater than the tax paid and the cost of capital during the holding period. This represents a substantial drain on the hours and attention of a founder who must manage their own tax compliance while building the firm.
