Why does Incorporation Basics and the 83(b) Election matter?
The 83(b) deadline is one of the few genuinely unforgiving dates in a founder's early timeline. There is no extension, no exception for not knowing, and missing it can turn what should be a near-zero tax event into a large, unplanned tax bill spread across the vesting period as the stock becomes worth more. It matters most precisely when it looks least urgent: right after incorporation, when the company is worth almost nothing and founders are focused on everything except paperwork with a filing deadline.
What does Incorporation Basics and the 83(b) Election look like in practice?
Suppose a founder is issued restricted stock immediately after incorporation, when the company's total value is negligible. Filing an 83(b) election within 30 days means paying tax now on that near-zero value, and none of the later appreciation as the stock vests is taxed as ordinary income at vesting, only at eventual sale, and typically at capital-gains rates. Skip the filing, and each vesting tranche becomes a taxable event valued at whatever the stock is worth on that vesting date, which can be substantial if the company has grown by then.
What are the common mistakes with Incorporation Basics and the 83(b) Election?
- Missing the 30-day window because it was not flagged as urgent relative to everything else happening right after incorporation.
- Assuming the company's legal counsel files it automatically. The IRS filing is the founder's personal responsibility, not the company's.
- Not sending it by a method that produces proof of mailing or receipt, which matters if the IRS ever questions the timing.
- Filing it for stock that is not actually restricted (fully vested at grant), where no election is needed or applicable.
