Section 83(b) Election and Form 15620: Restricted Property Practitioner Guide

The Section 83(b) election is one of the most time-sensitive and consequential elections in the tax code for founders, early employees, and the practitioners who advise them. Made correctly, it converts what would have been a large ordinary income inclusion at vesting into a modest income event at grant, with all subsequent appreciation taxed at capital gain rates. Missed by even one day, it is gone permanently. No other common tax election has a filing window this short, a consequences-of-failure this stark, and a relief mechanism this nonexistent.

The July 2025 launch of Form 15620, the IRS electronic portal for Section 83(b) elections, updates the filing mechanics but changes none of the underlying law. The 30-day clock, the ineligibility of RSUs, the forfeiture risk, and the QSBS holding period interaction are all unchanged. This guide covers each element of the election in full practitioner detail, with every material fact hedged to the applicable authority at IRS.gov, the IRC, or published guidance.

This guide is informational and does not constitute tax or legal advice for any specific client situation. All statutory citations, regulatory references, and procedural steps must be verified against current law and IRS.gov guidance before application in practice.

Section 1: IRC 83 Overview -- Restricted Property Rules

What IRC 83 governs

IRC 83 governs the federal income tax treatment of property transferred in connection with the performance of services. It applies when an employer, partnership, or other payor transfers property (typically stock, but also options, partnership interests, or other assets) to an employee or service provider as compensation. The statute determines when and how much income must be recognized by the recipient.

The default rule: taxation at vesting

Under the default rule of IRC 83(a), property transferred in connection with services is not included in gross income until the property is either (a) no longer subject to a substantial risk of forfeiture, or (b) freely transferable. The taxable event is vesting, not the initial transfer. At vesting, the recipient includes in ordinary income the excess of the fair market value of the property at vesting over the amount (if any) paid for the property. This ordinary income is compensation, subject to income tax and employment taxes.

Substantial risk of forfeiture

Property is subject to a substantial risk of forfeiture (SRF) if the recipient's rights to the property are conditioned on the future performance of substantial services, or on the occurrence of a condition related to the purpose of the transfer, and if the possibility of forfeiture is substantial. Typical vesting conditions that create an SRF include: continued employment for a set period (time-based vesting), achievement of specific performance milestones (performance-based vesting), or both. Hedge the specific SRF analysis to the Section 83 regulations and IRS.gov.

Why the default rule is costly for rapidly appreciating assets

For assets that appreciate substantially between the transfer date and vesting, the default rule under IRC 83(a) produces a large ordinary compensation income inclusion at vesting. A founder who receives restricted stock worth $0.01 per share at grant, subject to a four-year vesting schedule, and whose stock is worth $10 per share at vesting will recognize ordinary income based on the $10 value, not the $0.01 value. That income is taxed at ordinary income rates, including self-employment or employment taxes. The Section 83(b) election is the mechanism that changes this outcome.

Where a founder contributes cash or property to a new corporation in exchange for stock, that stock is generally received tax-free under IRC 351, not as compensation. Stock received for services, by contrast, is not covered by IRC 351 (services are not property) and is taxable compensation, which is where the Section 83(b) analysis in this guide applies. For the control test, boot rules, and the property-versus-services distinction at incorporation, see the IRC 351 tax-free incorporation guide.

Section 2: The Section 83(b) Election -- Mechanics and Tax Effect

What the election does

IRC 83(b) allows the recipient of restricted property to elect to include the fair market value of the property in income at the time of transfer, rather than waiting until vesting. By making this election, the recipient accelerates income recognition to a point when the FMV is typically low (often at or near the amount paid), trades an ordinary income inclusion at vesting for a small ordinary income inclusion at transfer, and converts all subsequent appreciation from ordinary compensation income into capital gain taxed at sale.

Tax consequences at each event: side-by-side comparison

The table below summarizes how the tax treatment differs at each event depending on whether the 83(b) election is made.

The primary advantage: ordinary income converted to capital gain

The central tax benefit of the Section 83(b) election is income character conversion. Without the election, all appreciation between grant and vesting is taxed as ordinary compensation income at vesting. With the election, only the value at grant is ordinary income; everything above that is capital gain upon sale. For startup stock that appreciates from a nominal value at grant to a significant value at vesting, the difference in after-tax proceeds between making and not making the election can be substantial. Hedge any quantitative comparisons to client-specific tax rates and facts; this guide does not represent specific tax savings amounts.

Basis and holding period after the election

After the 83(b) election, the recipient's tax basis in the property is equal to the FMV at the time of transfer plus the amount paid for the property. The holding period for long-term capital gain treatment begins on the date of the transfer (the election date), not on the vesting date. Property held for more than one year from the transfer date qualifies for long-term capital gain rates upon sale.

Section 3: The 30-Day Deadline -- No Exceptions

The statutory rule: IRC 83(b)(2)

IRC 83(b)(2) requires that the Section 83(b) election be made not later than 30 days after the date of the transfer of the property. The transfer date is the date the property is actually transferred to the taxpayer -- typically the grant date for restricted stock -- not the vesting date, not the date the grant agreement is signed after the grant date, and not the date the taxpayer becomes aware of the grant.

No reasonable cause exception

Unlike many IRS deadlines -- where the taxpayer may seek relief by showing reasonable cause for a late filing -- the Section 83(b) election deadline has no reasonable cause exception. It does not matter whether the taxpayer was unaware of the election, did not receive timely legal advice, was hospitalized, or had the election prepared and ready but failed to submit it in time. The 30 days is counted from the transfer date regardless of circumstances, and no relief is available from the IRS or the Tax Court after it passes.

Practitioner responsibility at the moment of grant

The 30-day window means that practitioners advising founders, early employees, or other compensatory property recipients must address the Section 83(b) election at the moment the grant occurs, not at year-end tax return preparation. By the time a client brings their grant documents to a tax return preparer in February or March of the following year, the deadline for any grant made in the prior year's first eleven months has already passed. Practitioners who do not have a system for flagging and advising clients on the 83(b) election at grant date are exposing their clients to a permanent and unrecoverable loss.

Form 15620: the 2025 electronic option

In July 2025, the IRS launched Form 15620, an electronic portal on IRS.gov for submitting Section 83(b) elections. This provides an alternative to the paper election process and may simplify compliance tracking. The electronic portal does not extend the 30-day deadline in any way. The filing must still be completed within 30 days of the transfer date. The paper election to the IRS Service Center where the taxpayer files remains valid; there is no requirement to use Form 15620. The IRS revised Rev. Proc. 2012-29 in connection with the Form 15620 launch. All Form 15620 portal mechanics, specific fields, and submission procedures are hedged to current IRS.gov guidance and the Form 15620 instructions, which may be updated by the IRS after the date of this guide.

Section 4: How to Make the Election

Required content of the election statement

Whether filed electronically via Form 15620 or on paper, the Section 83(b) election must contain certain information. Per current guidance (hedge to current Form 15620 instructions and IRS.gov, as requirements may be updated), the election statement generally must include:

• The taxpayer's name, address, and taxpayer identification number (TIN)
• A description of the property with respect to which the election is being made
• The date or dates on which the property was transferred and the taxable year for which the election is being made
• The nature of any restriction(s) to which the property is subject
• The fair market value at the time of transfer (determined without regard to any lapse restriction)
• The amount (if any) paid for the property
• A statement that copies have been provided to the employer or partnership

Hedge all content requirements to the current Form 15620 instructions on IRS.gov before preparing an election for a client. Requirements may be updated as the IRS operationalizes the electronic portal.

Electronic method: Form 15620 on IRS.gov

As of July 2025, taxpayers may submit the Section 83(b) election electronically through Form 15620 on IRS.gov. The electronic portal provides a direct submission path and may generate a filing confirmation that serves as documentation of timely filing. All specific portal fields, the submission workflow, and instructions for completing Form 15620 electronically are governed by the current Form 15620 instructions on IRS.gov. This guide does not reproduce those instructions because they may be revised by the IRS; consult IRS.gov directly.

Paper method: still valid, no requirement to use Form 15620

The paper election remains a valid submission method. File a signed statement containing all required items with the IRS Service Center where the taxpayer files their income tax return. The paper election must be postmarked or delivered within the 30-day window. Retain a copy of the election and proof of timely filing (certified mail receipt or comparable documentation) as permanent client records.

Copy to employer or partnership

A copy of the election must be provided to the employer or partnership within 30 days of the transfer date, consistent with the IRS filing. The employer uses this copy to comply with their own reporting obligations. Hedge the exact employer copy requirement to current IRS.gov guidance.

Copy attached to tax return

A copy of the election must also be attached to the taxpayer's income tax return for the taxable year in which the transfer occurred. The election is filed with the IRS before the tax return for the year of transfer is due; the copy attached to the tax return provides a cross-reference in the taxpayer's filing record.

State filing requirements

Some states, including California, require a copy of the Section 83(b) election to be filed with the state as well, typically with the state income tax return for the year of transfer. State-specific filing requirements vary significantly across jurisdictions and may differ from the federal requirements in timing, form, or content. Verify the applicable state tax authority's requirements before completing the state compliance step. Do not assume that federal compliance satisfies any state filing obligation.

Section 5: RSUs -- Not Eligible for the Section 83(b) Election

The single most common 83(b) election misunderstanding in practice is the belief that RSU holders can or should make the election. They cannot. The law is clear, and practitioners must communicate this without ambiguity.

Why the distinction matters in practice

The tax treatment of RSUs and restricted stock diverges significantly at vesting. For restricted stock with a timely 83(b) election, vesting is a non-event; the recipient already recognized income at grant. For RSUs, vesting is always the taxable event: the fair market value of the shares delivered at vesting is ordinary compensation income in the year of vesting, subject to income tax and employment taxes at delivery. There is no mechanism to accelerate RSU income to an earlier date when the value may be lower.

A client holding RSUs who asks about the Section 83(b) election is asking about an election that is not available to them. Practitioners should not attempt to adapt the 83(b) framework to RSU grants, nor should they suggest that the new Form 15620 portal changes this analysis. RSU ineligibility is a function of the underlying property transfer requirement in IRC 83(b), not a procedural gap that Form 15620 addresses. Hedge to IRS.gov and the Section 83 regulations when counseling clients on the restricted stock versus RSU distinction.

Identifying grant type in client engagements

Grant agreements and offer letters do not always clearly label the award as restricted stock or RSUs. Practitioners should obtain and review the actual grant documentation, consult the company's equity plan, and confirm the award type before advising on 83(b) eligibility. Key indicators: restricted stock agreements typically transfer shares to the recipient at grant subject to a repurchase right or forfeiture condition; RSU award agreements typically describe a right to receive shares at a future delivery date. When the characterization is unclear from the documents, the analysis must be resolved before the 30-day window closes.

Section 6: Partnership Profits Interests and Capital Interests

Profits interests under Rev. Proc. 93-27

Rev. Proc. 93-27 provides that a partnership profits interest received for services is generally not taxable at grant. The rationale: because a profits interest entitles the holder only to a share of future profits (not the current liquidating value of the partnership), its fair market value at grant is effectively zero. With no FMV to include in income and no transfer of property with positive value, the ordinary income consequence at grant is zero, and there is typically no tax driver for a Section 83(b) election on a pure profits interest. All profits interest specifics are hedged to Rev. Proc. 93-27, Rev. Proc. 2001-43, and current IRS.gov guidance.

Vesting and Rev. Proc. 2001-43

Rev. Proc. 2001-43 addresses profits interests that are subject to vesting conditions. Under that guidance, if the partnership and the service provider treat the service provider as a partner from the grant date (rather than from the vesting date) and meet the applicable requirements, the service provider is treated as receiving the profits interest at grant for tax purposes -- regardless of the vesting schedule. This deemed-receipt treatment under Rev. Proc. 2001-43 functions similarly to a Section 83(b) election in its practical effect for profits interests: it starts the holding period from the grant date and avoids the income recognition issue at vesting. Hedge the application of Rev. Proc. 2001-43 to specific partnership arrangements to IRS.gov and tax counsel.

When the 83(b) election is relevant for partnership interests

A Section 83(b) election may be warranted for a partnership interest in two primary circumstances:

• Capital interests (not pure profits interests): if the partnership interest has current liquidating value at grant -- meaning the holder would receive a positive amount upon an immediate liquidation of the partnership -- it is a capital interest rather than a pure profits interest. Rev. Proc. 93-27's non-taxability treatment does not apply to capital interests. For a capital interest received subject to vesting, the Section 83(b) election accelerates the ordinary income inclusion to the grant date, when the value may be lower, and starts the capital holding period for long-term gain treatment.
• Profits interests with floor rights or hybrid features: some partnership awards include floor guarantees, minimum returns, or other features that give them determinable value at grant even if they are structured as profits interests. Interests with such features may fall outside Rev. Proc. 93-27's safe harbor. In those situations, an 83(b) election (or a careful analysis of whether one is required) is appropriate.

The distinction between profits interests and capital interests, and the application of Rev. Proc. 93-27 and Rev. Proc. 2001-43 to specific award structures, is fact-specific and involves the interpretation of current IRS guidance. Hedge all partnership interest analysis to those authorities and current IRS.gov guidance.

Section 7: QSBS Interaction (IRC 1202)

What QSBS treatment requires

IRC 1202 provides an exclusion from gain on the sale of Qualified Small Business Stock (QSBS) held for more than five years. Both the taxpayer and the issuing corporation must satisfy the eligibility requirements of IRC 1202, which include requirements on the corporation's size, active business activities, and the manner in which the stock was originally issued. The QSBS exclusion applies only to stock in a C-corporation; S-corporation stock and partnership interests do not qualify. Hedge all QSBS eligibility specifics, including the exclusion percentage applicable to any particular grant, to IRC 1202 and IRS.gov. Do not state a specific exclusion percentage in client communications without verifying the current applicable percentage at IRS.gov.

The C-corporation requirement for QSBS has direct relevance to the Section 83(b) election and the IRC 1374 built-in gains tax. A company must be organized as a C-corporation to issue QSBS; employees of S-corporations or LLCs cannot hold QSBS. For a detailed analysis of the built-in gains tax implications of converting a C-corporation to S-corporation status (which would terminate future QSBS eligibility), see the IRC 1374 Built-In Gains Tax: C-Corp to S-Corp Conversion Practitioner Guide.

How the 83(b) election advances the QSBS five-year holding period

The five-year holding period for the QSBS exclusion under IRC 1202 begins when the taxpayer acquires the stock. For restricted stock subject to a vesting schedule, the critical question is: when is the stock "acquired" for QSBS holding period purposes?

The answer depends on whether the Section 83(b) election is made:

Startup planning implications

For a founder or early employee receiving restricted stock in a startup organized as a C-corporation that may qualify as a qualified small business, the Section 83(b) election serves two goals simultaneously: it minimizes the ordinary income recognized at grant (when the stock value is low), and it starts the five-year QSBS holding period as early as possible. An employee who receives restricted stock on January 1, 2026, makes the 83(b) election by January 31, 2026, and holds the stock until January 1, 2031, satisfies the five-year QSBS holding period and may be eligible for the IRC 1202 exclusion on the gain upon sale -- subject to all other QSBS requirements being met. Without the election, the five-year clock would not begin until the shares vest, which on a four-year vesting schedule could be as late as January 1, 2030, pushing the QSBS exclusion date to January 1, 2035. For the full qualification framework, the active business test, the original issuance requirement, and the OBBBA changes affecting stock issued after July 4, 2025, see our IRC 1202 QSBS exclusion guide.

For additional context on capital gain planning strategies relevant to equity in qualified businesses, see the Qualified Opportunity Zone Form 8997 and 2026 Gain Recognition Practitioner Guide, which covers capital gain deferral and exclusion mechanics under IRC 1400Z-2.

When an early employee or founder holds equity in a company that later goes public, that individual may become a covered employee of a publicly held corporation, at which point the employer's deduction for compensation above the statutory threshold is disallowed. Practitioners advising on IPO-track stock grants should understand the employer-side consequences: see the IRC 162(m) executive compensation deduction limit guide.

Section 8: The Forfeiture Risk

The Section 83(b) election is not without risk. The principal risk is forfeiture: if the taxpayer does not fulfill the vesting conditions (most commonly because they leave the company before vesting is complete), the property is returned, but the tax consequences of the election are not reversed.

Illustrative scenario

Consider the following scenario (hypothetical; hedge all tax positions to client-specific facts and current law):

• An employee receives restricted stock with a fair market value of $50,000 at grant, subject to four-year vesting. The employee pays $0 for the stock.
• The employee timely makes the Section 83(b) election and includes $50,000 in ordinary income in the year of grant, paying income and employment taxes on that amount.
• The employee is terminated at the end of Year 2, before the stock fully vests. The unvested shares are forfeited, and the employee receives $0 in connection with the forfeiture.
• The employee cannot deduct the $50,000 previously recognized as income. Because the amount paid was $0, and the forfeiture consideration was $0, there is no capital loss either. The tax paid on the $50,000 ordinary income is a permanent cost with no offsetting benefit from the equity.

Advising clients on forfeiture risk

Before advising a client to make the Section 83(b) election, practitioners should ensure the client understands the forfeiture risk explicitly. Relevant considerations include:

• The realistic probability that the client will remain with the company through the vesting period
• The financial cost of the ordinary income recognized at grant: if the FMV at grant is high, the election triggers a real tax cost at the time of grant, regardless of what happens later
• The financial stability and prospects of the company: startup risk means forfeitures are more likely, but the upside of the election is also greater if the company succeeds
• Whether there is a meaningful amount of actual cash or value at risk: if the company's stock is worth $0.001 per share at grant and the total ordinary income is a few dollars, the forfeiture risk is immaterial; if the grant carries a material current value, the analysis is different

The election is typically advisable when the stock is worth very little at grant, the expected appreciation is significant, and the taxpayer has reasonable confidence in satisfying the vesting conditions. The election carries more risk when the current value is meaningful, the vesting period is long, or the taxpayer's continued service is uncertain.

Section 9: Documentation and Filing Checklist

The following checklist covers the steps for a Section 83(b) election from grant date through tax return filing. All steps should be verified against current IRS.gov guidance and Form 15620 instructions before use in a client engagement.

On the grant date

• Identify and confirm the award type: restricted stock (eligible for 83(b)) or RSUs (NOT eligible). Review the grant agreement and equity plan documentation.
• Confirm the transfer date (the date the property is actually transferred to the taxpayer, typically the grant date for restricted stock). Record this date precisely. The 30-day deadline runs from this date.
• Determine the fair market value of the property at the time of transfer. For private company stock, this typically requires a Section 409A valuation. Proper FMV documentation is important to defend the income amount on audit.
• Confirm the amount paid for the property, if any (many compensatory grants involve $0 purchase price or nominal consideration).
• Calendar the 30-day filing deadline and set a compliance alert. Do not rely on year-end tax review to catch 83(b) elections; the deadline will have passed for grants made before December 2.

Within 30 days of the grant date (mandatory)

• Prepare the 83(b) election statement containing all required items (taxpayer information, property description, transfer date, tax year, restrictions, FMV, amount paid). Hedge content requirements to current Form 15620 instructions and IRS.gov.
• File the election with the IRS. Option A: submit electronically via Form 15620 on IRS.gov (retain the electronic filing confirmation as documentation). Option B: file the signed paper statement with the IRS Service Center where the taxpayer files their return (use certified mail or other delivery with postmark confirmation and retain the receipt).
• Provide a copy of the election to the employer or partnership within the same 30-day window. Retain confirmation of delivery.

By the income tax return due date (including extensions)

• Attach a copy of the 83(b) election to the taxpayer's federal income tax return for the taxable year in which the transfer occurred (e.g., if the grant date was in 2026, attach to the 2026 Form 1040 filed in 2027).
• Report the ordinary income recognized on the election (FMV at transfer minus amount paid) in the appropriate line of the return. Confirm with the employer's W-2 or 1099 for the year to verify that the compensation amount is consistent.

State filing (jurisdiction-specific)

• Verify whether the taxpayer's state of residence (and, if different, the state in which the services are performed) requires a copy of the 83(b) election to be filed with the state return. California and certain other states require a state filing. Verify with the applicable state tax authority.
• Complete any required state 83(b) filing consistent with the state authority's requirements. Retain confirmation of the state filing.

Ongoing documentation

• Retain copies of the 83(b) election, the IRS filing confirmation (electronic receipt or certified mail receipt), the employer copy delivery confirmation, and the state filing confirmation in the client's permanent file. These records are needed to establish the basis and holding period on a future sale, which may occur years later.
• Document the FMV determination at the time of transfer (Section 409A valuation report or other FMV support). This documentation defends the income amount reported on the 83(b) election on audit.
• Maintain the tax basis calculation (FMV at transfer plus amount paid) for use when the property is ultimately sold. Verify that the basis and holding period are correctly carried forward in the client's records each year.
