Restricted stock can create tax before a founder has cash
Verified against current federal sources as of August 10, 2026.
A founder can buy stock early, watch the company grow, and still owe tax before any sale happens.
That happens because restricted founder stock is often subject to vesting, repurchase rights, or forfeiture conditions. Under the default Section 83 rule, substantially nonvested property transferred for services is generally taxed when it becomes transferable or is no longer subject to a substantial risk of forfeiture.
For founder stock, that can mean compensation income as blocks of shares vest. The company may be worth more by then, while the founder still has no buyer, no exit, and no cash from the shares.
The 83(b) election exists because the tax event and the cash event can arrive years apart.
What is an 83(b) election?
An 83(b) election tells the IRS to apply the federal Section 83 income rule when substantially nonvested property is transferred instead of when it later vests.
The election is made under Section 83(b). A founder includes in income the difference between the property's fair market value at transfer and the amount paid for it.
| Item | What it means | Why founders care |
|---|---|---|
| Fair market value | Tax value of the property at transfer, ignoring lapse restrictions | This drives the taxable spread |
| Amount paid | What the founder actually paid for the transferred property | This is not the same as par value |
| Section 83 income | Fair market value minus amount paid | A zero spread can mean no Section 83 income at transfer |
| Ownership record | Board approval, stock purchase, payment, ledger, and cap table evidence | The tax filing cannot fix a bad issuance |
The election is strongest when fair market value and purchase price are supportable and close together at the transfer date.
If a founder pays $1,000 for restricted stock with a supported fair market value of $1,000 on the transfer date, the taxable spread is zero. A timely election can produce zero Section 83 income at transfer and no additional Section 83 compensation merely because those same shares later vest.
The election changes tax timing. It does not make future appreciation tax free, set fair market value, create ownership, or guarantee capital gain treatment.
The election applies to transferred property, not every equity promise
An 83(b) election is relevant only when property has been transferred in connection with services and remains substantially nonvested.
Founders often use loose language around grants, awards, shares, options, and equity. The tax rule cares about what legal rights actually moved.
| Equity situation | 83(b) relevance | Founder note |
|---|---|---|
| Restricted founder common stock subject to reverse vesting | Often relevant | The founder owns shares but may lose unvested shares if service ends |
| Restricted stock award | Often relevant | Actual shares have been transferred with forfeiture risk |
| Early exercise of an option into unvested shares | Often relevant, but review the documents | The election relates to acquired shares, not merely the option grant |
| Incentive stock option exercised early | Specialist review required | ISO, AMT, holding period, and disqualifying disposition rules can interact |
| Restricted stock units at grant | Usually not relevant | An RSU is generally a promise to deliver stock or cash later |
| LLC or partnership interest for services | Fact specific | Capital interests, profits interests, and partnership tax rules require tailored advice |
The document label is not enough. Counsel should confirm whether transferred property exists for Section 83 purposes.
The IRS gives founders 30 days from the stock transfer
The filing deadline is 30 days after the property is transferred, not 30 business days.
That date is not automatically the incorporation date, board approval date, signature date, certificate date, or cap table update. Treasury Regulation Section 1.83-3 says a transfer occurs when a person acquires a beneficial ownership interest in the property.
Approvals, payment, stock ledger entries, vesting terms, state corporate law, and the actual issuance record can all matter. Ask counsel to identify the transfer date from the full record and put the deadline in writing.
The April 2025 IRS Form 15620 instructions include a weekend and legal holiday rule for paper elections when the thirtieth day falls on one of those days. Treat that as a narrow counting rule, not permission to wait.
Filing correctly means matching the election to the stock record
A correct 83(b) election is not just a form. It is a tax filing that should match the actual issuance record.
1Confirm that the stock was actually transferred
Collect the board consent, stock purchase agreement, vesting or repurchase terms, proof of payment, stock ledger entry, certificate or electronic issuance record, and cap table.
The election should describe property that was actually transferred. A tax form cannot supply missing board approval, payment, issuance, or ownership rights.
2Separate par value, purchase price, and fair market value
Par value, purchase price, and fair market value are not interchangeable. Par value is a corporate law number. Purchase price is what the founder paid. Fair market value is the tax value at transfer.
Do not automatically copy the charter's par value into the fair market value field. The company and its advisers should support fair market value using the transfer-date facts.
3Use Form 15620 or a compliant written statement
The IRS provides Form 15620, Section 83(b) Election. Its use is voluntary. A signed written statement that contains the items required by Treasury Regulation Section 1.83-2(e) may still be used.
As of August 10, 2026, the IRS lists Form 15620 as a mobile-friendly form that requires an IRS Online Account, and the IRS online Form 15620 page redirects to the authenticated online form. The downloadable PDF instructions still describe filing by mail with the IRS office where the service provider files a federal return.
4Give the required copy to the company
Treasury Regulation Section 1.83-2(d) requires the service provider to give a copy to the person for whom the services are performed. If the service provider and property transferee are different people, the transferee must also receive a copy.
5Keep proof with the ownership record
Preserve the signed election, electronic confirmation or mailing proof, company copy delivery evidence, fair market value support, stock purchase documents, proof of payment, stock ledger, and cap table together.
For property transferred on or after January 1, 2016, a copy is no longer required with the founder's federal income tax return. The IRS removed that former federal return-copy requirement in Treasury Decision 9779. A founder still must report any income and check state requirements.
A zero spread today can prevent taxable compensation at vesting
The practical benefit is easiest to see when the taxable spread is zero or small on the transfer date.
Assume a founder acquires 1,000,000 shares on January 10. The shares are subject to four-year reverse vesting. The founder pays $0.001 per share, or $1,000 total. The supported fair market value is also $0.001 per share, or $1,000 total.
| Scenario | Calculation | Section 83 income |
|---|---|---|
| With timely 83(b) election at transfer | $1,000 fair market value minus $1,000 paid | $0 |
| Without election when 250,000 shares vest at $1 each | $250,000 fair market value minus $250 allocated purchase price | $249,750 |
This simplified example does not calculate federal rates, employment taxes, state taxes, withholding, alternative minimum tax, future sale gain, or QSBS treatment.
Treasury Regulation Section 1.83-4 says that when a valid election is made, the holding period begins just after the property transfer. Without the election, the Section 83 holding period generally starts when the property becomes substantially vested.
That earlier start can matter for long-term capital gain and for the holding-period analysis under Section 1202, commonly called qualified small business stock or QSBS.
But an 83(b) election does not guarantee QSBS. QSBS depends on separate C corporation, original issuance, gross asset, active business, holding period, shareholder, and sale requirements.
The downside is forfeiture, valuation risk, and missed deadlines
An 83(b) election moves income forward because the founder is choosing today's taxable spread over whatever the value may be when the stock vests.
That creates forfeiture and valuation risk. The stock may decline in value. The company may fail. The founder may leave before all shares vest. The company may repurchase or the founder may forfeit unvested shares.
If elected property is later forfeited while still substantially nonvested, Treasury Regulation Section 1.83-2 generally limits the loss to the amount paid over any amount received on forfeiture. The founder does not simply reverse previously recognized compensation income.
The election is also difficult to revoke. IRS consent is generally required, and the regulation limits consent to mistake-of-fact situations. A mistake about value, a later decline in value, or the failure to perform an expected act is not treated as that kind of mistake.
There is no routine late election form and no ordinary extension request founders should expect to rescue a missed deadline. Do not backdate documents, alter the transfer date, or mail a late election as though it were timely. The goal after a missed deadline is an accurate assessment, not a fictional paper trail.
Founder action checklist
- Confirm whether actual property was transferred for services.
- Identify every restriction, vesting term, repurchase right, and forfeiture condition.
- Have counsel confirm the legal transfer date.
- Record the 30-day deadline immediately.
- Confirm the share quantity, class, issuer, and recipient.
- Verify the amount actually paid and preserve proof of payment.
- Support fair market value separately from par value and purchase price.
- Complete and sign Form 15620 or a compliant election statement.
- File through a current IRS route before the deadline.
- Give the required copy to the company and any separate transferee.
- Preserve the election with the company's ownership and governance records.
- Review QSBS separately if the company and stock may qualify.
Build the ownership record before the value grows
An 83(b) election is one document. The protection comes from being able to show what the company approved, what the founder bought, when ownership transferred, what restrictions applied, what value was used, when the election was filed, and where the proof lives.
EntityEngine helps founders form and organize the business, connect ownership and governance records, track critical compliance work, and preserve the history behind important company decisions.
It does not decide whether you should make an 83(b) election or replace your lawyer or tax adviser. It helps you build the corporate records those advisers need to review.
You may spend years building the value of your company. Build the record that helps protect that value from the beginning.
