Restricted Founder Shares and the 83(b) Election: Start the Clock at Transfer

A restricted share grant can create compensation timing choices

When property is transferred for services subject to substantial forfeiture restrictions, Section 83 generally taxes the excess of fair market value over the amount paid when the property becomes substantially vested. A valid Section 83(b) election can instead include that excess in income at transfer. The IRS election instructions require filing no later than thirty days after the property transfer. The transfer date, not a later board discussion or the first tax meeting, starts that deadline.

The election changes timing and risk; it does not guarantee the shares will grow or make every grant tax-free. If the value at transfer exceeds the purchase price, current compensation income can arise. If the shares are later forfeited, tax paid because of the election may not be recoverable through a deduction for the previously included amount. Confirm the actual award and tax consequences before filing or deciding not to file.

A hypothetical restricted-stock purchase

Assume a founder acquires restricted shares for $10,000 when their supported fair market value is $12,000. A timely election would generally use the $2,000 difference in the current compensation analysis, subject to the applicable rules. Without the election, suppose the shares later vest when worth $100,000 and the original price remains $10,000. The potential $90,000 spread illustrates how later appreciation can affect compensation timing under the stated simplified facts.

These values are hypothetical and assume actual property subject to Section 83, not merely a promise of future shares. The advisor needs the final stock agreement, purchase payment, restrictions, vesting, transfer date, and valuation support. Restricted stock units and other awards can have different mechanics. Do not file an election solely because a document contains the word restricted without confirming that property was transferred and the election is applicable.

If the founder leaves before vesting and forfeits the shares, the commercial loss and tax consequences need separate review. A small initial taxable spread may look attractive in a successful-growth scenario, while a larger spread can create meaningful current tax risk if the shares fail. Compare both outcomes using supported values rather than assume growth is inevitable.

Coordinate grant execution and tax review

Counsel should identify the actual transfer and restrictions; the advisor should explain Section 83 treatment and whether the election is appropriate. Payroll may need compensation and withholding instructions. The founder’s personal preparer should receive the final documents and election evidence. A signed stock purchase agreement stored only in the legal data room can leave the tax team unaware that a short deadline is running.

Use the current IRS Form 15620 instructions or another valid election statement as advised. Confirm required information, signatures, delivery method, recipient copies, and filing evidence. Do not assume attaching a statement to a later annual return cures a missed thirty-day deadline. Keep the mailing or electronic submission proof supported by the chosen process, along with the exact election filed.

Preserve basis and vesting history

Maintain the purchase price, compensation included, election, valuation support, vesting events, forfeitures, and later transfers. These records support both ongoing reporting and eventual sale calculations. The company’s capitalization table identifies shares but may not preserve the founder’s tax basis or compensation history. Keep those measures distinct and deliver the relevant information to the personal preparer.

If the grant changes before transfer, update the tax review. A revised purchase price, vesting condition, or share count can alter the calculation. If the change occurs afterward, obtain advice rather than rewrite the original election informally. The file should show what was actually transferred and elected at each relevant date.

Make the decision while the deadline is available

This guide does not recommend an election for a specific founder or determine stock value. It gives the founder an actionable sequence: identify the actual property transfer, compare current and later income outcomes, evaluate forfeiture risk, and complete any advised election within the applicable deadline. The decision should be informed by the actual award rather than discovered during return preparation after the election window has passed.

Record the transfer date in the founder’s calendar immediately when the closing documents are executed.
