Why 83(b) election matters to a first-time founder
If you receive restricted shares in the US that vest over time, an 83(b) election changes when their value counts as income for US federal tax. Filing while the shares are worth little may reduce the tax due as they vest and grow in value. But you may pay tax before you know whether you will keep them.
Examples of 83(b) election
A US founder buys 1,000,000 restricted shares for $1,000 when the company is formed. The shares vest over four years. By filing an 83(b) election on time, the founder reports their current value as income now instead of reporting part of their rising value as pay each time another group of shares vests.
Common misunderstanding
The election does not remove tax, guarantee savings or stop you losing unvested shares. If you leave and the company buys back or takes those shares, you may not recover tax already paid because of the election. The filing deadline is generally 30 days after the shares are transferred, not 30 days after vesting starts.
When to use it
Consider it as soon as you receive restricted stock that vests in the United States. The deadline is strict. The result depends on what you paid, what the shares are worth now, the vesting terms and your tax position. Ask a qualified US tax adviser whether filing is right for you; this is not personal tax advice.
