IRC §83(b) (Property transferred in connection with performance of services - election to include in gross income in year of transfer) lets a service provider who receives RESTRICTED PROPERTY (typically unvested equity subject to a substantial risk of forfeiture) ELECT to be taxed on the property's value AT THE TIME OF TRANSFER rather than waiting until it VESTS. DEFAULT RULE §83(a): when property received for services is subject to a SUBSTANTIAL RISK OF FORFEITURE, the service provider recognizes ORDINARY INCOME equal to FMV minus amount paid WHEN the property VESTS (when risk of forfeiture lapses) - measured at the THEN-current value. For appreciating equity, this means tax on a much higher value at vesting. §83(b) ELECTION: service provider elects to include in income the EXCESS of FMV at GRANT over amount paid, in the YEAR OF TRANSFER - locking in a low (often zero) taxable amount at grant, with all future appreciation taxed as CAPITAL GAIN on eventual sale rather than ordinary income at vesting. STRICT 30-DAY DEADLINE: the §83(b) election MUST be filed with the IRS within 30 DAYS of the property TRANSFER (grant of restricted stock, or exercise of an option for early-exercised shares). NO EXTENSIONS, NO EXCEPTIONS - a single day late is fatal. WHAT IT APPLIES TO: restricted stock awards (RSAs); shares acquired by EARLY EXERCISE of stock options (ISO or NSO) before vesting; founder stock subject to vesting. WHAT IT DOES NOT APPLY TO: restricted stock UNITS (RSUs) - no property transferred at grant, only a promise; unexercised options. MECHANICS OF BENEFIT: founder receives 1,000,000 shares at $0.001 ($1,000 FMV); files §83(b); pays ordinary income tax on $1,000 (or less); holds; sells years later at $5,000,000; entire $4,999,000 gain is LONG-TERM CAPITAL GAIN. Without election, taxed at ordinary rates on FMV at each vesting date as shares vest - potentially millions in ordinary income with no liquidity. RISK: if forfeited after election, NO deduction for amount previously included (only loss is amount paid). HOLDING PERIOD starts at grant for §83(b) electors (vs at vesting otherwise) - critical for 1-year LTCG and §1202 QSBS 5-year holding. FORM 15620 - IRS released standardized §83(b) election form in November 2024 (use optional; written statement still acceptable). §83(i) - separate 5-year deferral election for private company "qualified equity grants" (not the same as §83(b)). Employer gets §83(h) deduction matching income included.
The default (§83(a)): Restricted property received for services is taxed as ORDINARY INCOME when it VESTS, at the THEN-current FMV. Appreciating equity gets taxed on a high value at vesting.
The election (§83(b)): Elect to be taxed NOW at grant-date value (often near zero for founders). All future appreciation becomes LONG-TERM CAPITAL GAIN on sale instead of ordinary income at vesting.
The 30-day rule: Must file with the IRS within 30 days of the property TRANSFER (restricted stock grant, or option early-exercise date). NO extensions, no exceptions. One day late is fatal.
Applies to: Restricted stock awards (RSAs) and early-exercised options. Does NOT apply to RSUs (no property at grant) or unexercised options.
The risk: If you forfeit the property after electing, no deduction for the income you already recognized (only the amount paid is a capital loss). Form 15620 standardized template released November 2024.
| Element | Detail |
|---|---|
| §83(a) default rule | Property transferred for services included in gross income when no longer subject to substantial risk of forfeiture (vesting); amount = FMV at vesting minus amount paid |
| Substantial risk of forfeiture §83(c)(1) | Rights conditioned on future performance of substantial services OR occurrence of condition related to transfer purpose; typical vesting schedule |
| §83(b) election | Elect to include in income at TRANSFER (grant) the excess of FMV at grant over amount paid; future appreciation NOT ordinary income at vesting |
| Character at grant | Ordinary compensation income (subject to payroll/withholding if employee) |
| Character on later sale | Capital gain/loss measured from FMV included at grant (basis) to sale price; long-term if held 1+ year from grant |
| Amount paid | If service provider pays FMV for stock (common for founders at formation), §83(b) income is $0 - but election still critical to start holding period and lock character |
| Holding period §83(b) | Begins on date of transfer (grant) for electors; begins at vesting if no election |
| Employer deduction §83(h) | Employer deducts amount included in service provider's income, in employer's tax year that includes the income inclusion date |
| Withholding | For employees, §83(b) income subject to FICA and income tax withholding at grant |
| Capital gain rate benefit | Future appreciation taxed at 0%/15%/20% LTCG rather than up to 37% ordinary |
| Filing Element | Detail |
|---|---|
| 30-day deadline §83(b)(2) | Election must be made not later than 30 days AFTER the date the property is transferred; STRICT - no extensions under Reg §301.9100 relief (statutory deadline) |
| Date of transfer - RSA | Grant date of restricted stock award (when stock issued/transferred to service provider) |
| Date of transfer - early-exercised option | Date of EXERCISE (when shares acquired), not grant of option; 30 days from exercise |
| Where to file | IRS office where service provider files income tax return; mail election statement |
| Copy to employer | Must furnish copy of election to employer/service recipient |
| Copy to return (historic) | Prior rule required attaching copy to tax return; IRS eliminated this requirement for elections after 2015 but retention recommended |
| Certified mail | Best practice - certified mail with return receipt for proof of timely filing |
| Form 15620 | IRS released standardized §83(b) election form November 2024; OPTIONAL - taxpayer may use own written statement with required information |
| Required information | Name, address, TIN; description of property; date of transfer and tax year; nature of restrictions; FMV at transfer; amount paid; amount to include in income; statement that copy furnished to employer |
| No extensions | Statutory 30-day deadline; missed deadline cannot be cured; election irrevocable once made (revocation only with IRS consent and only for mistake of fact) |
Facts: Anna co-founds a startup in January 2026. She receives 2,000,000 shares of founder restricted stock subject to 4-year vesting (25% per year). At grant, FMV = $0.001/share (par value); Anna pays $2,000 (par). The company's value will grow substantially.
Scenario A - WITH §83(b) election (filed within 30 days):
At grant January 2026: income = (FMV $2,000) - (paid $2,000) = $0 ordinary income
Anna files §83(b) within 30 days; pays $0 tax (or minimal); basis $2,000; holding period starts January 2026
4 years later (2030), all shares vested; company acquired; Anna sells 2,000,000 shares at $10/share = $20,000,000
Gain: $20,000,000 - $2,000 = $19,998,000 LONG-TERM CAPITAL GAIN
Federal tax at 20% LTCG + 3.8% NIIT = 23.8% × $19,998,000 = $4,759,524
Scenario B - WITHOUT §83(b) election:
No tax at grant. As each tranche vests, ordinary income = FMV at vesting minus $0.001 paid.
Year 1 vest (500,000 shares), FMV grown to $1/share: ordinary income $500,000
Year 2 vest (500,000 shares), FMV $3/share: ordinary income $1,500,000
Year 3 vest (500,000 shares), FMV $6/share: ordinary income $3,000,000
Year 4 vest (500,000 shares), FMV $10/share: ordinary income $5,000,000
Total ordinary income over vesting: $10,000,000 taxed at up to 37% + payroll taxes, WITHOUT liquidity to pay
Federal ordinary tax (37%): approximately $3,700,000 spread over 4 years, plus the post-vesting appreciation to $20M sale taxed separately
Worse: ordinary rates on $10M of vesting income, illiquid shares, no cash to pay tax
The §83(b) advantage:
Scenario A: ~$4.76M total tax, all capital gain, paid only at liquidity event
Scenario B: ~$3.7M ordinary tax at vesting (no liquidity) PLUS capital gains tax on later appreciation; much higher total; severe cash-flow problem at each vesting
§83(b) converts millions of ordinary income into capital gain and defers all tax to the liquidity event.
The risk if Anna leaves early:
If Anna forfeits unvested shares (leaves after year 2), she gets NO deduction for the $0 income she recognized (here minimal since income was $0). For higher grant-value situations, the §83(b) income recognized but later forfeited is lost with only a capital loss for amounts PAID. With $0 income, downside is minimal - which is why §83(b) is near-automatic for founder stock at formation.
| Equity Type | §83(b) Availability |
|---|---|
| Restricted Stock Award (RSA) | YES - property (stock) transferred at grant subject to forfeiture; file within 30 days of grant |
| Early-exercised stock options (ISO/NSO) | YES - if plan permits early exercise, exercising before vesting transfers restricted stock; file within 30 days of EXERCISE |
| Founder stock | YES - typically subject to vesting; §83(b) near-universal at formation when FMV minimal |
| Restricted Stock Units (RSU) | NO - RSU is unfunded promise to deliver shares at vesting; no property transferred at grant; nothing to elect on |
| Unexercised stock options | NO - option itself generally not "transferred property"; must exercise first (for early-exercise plans) |
| Vested stock (no restrictions) | NO ELECTION NEEDED - already taxed at grant as ordinary income; no risk of forfeiture |
| Profits interest (partnership) | Different regime - Rev. Proc. 93-27 / 2001-43; §83(b) protective election common for safe harbor |
| Stock appreciation rights (SARs) | NO - cash/phantom right, not property |
| Phantom stock | NO - deferred compensation, not property transfer |
| ISO shares (regular vesting) | ISO has own rules; AMT preference at exercise; §83(b) relevant for early-exercised ISO to start holding period and limit AMT |
| Option Type | §83(b) Interaction |
|---|---|
| NSO early exercise + §83(b) | Exercise before vesting; §83(b) locks ordinary income at spread (FMV minus strike) at exercise; if strike = FMV, $0 income; future gain is capital |
| NSO without early exercise | Ordinary income on spread at exercise (when vested); §83(b) not applicable to vested exercise |
| ISO early exercise + §83(b) | §83(b) starts holding period; ISO AMT preference equals spread at exercise; if early exercised at low spread, minimizes AMT; §83(b) protects against AMT on future appreciation at vesting |
| ISO qualifying disposition | Hold 2 years from grant AND 1 year from exercise for all-LTCG treatment; §83(b) on early exercise starts the 1-year clock at exercise |
| ISO AMT adjustment §56(b)(3) | ISO spread at exercise is AMT preference item; early exercise + §83(b) with minimal spread reduces AMT exposure |
| NSO §83(b) and §409A | NSO with exercise price below FMV may have §409A deferred comp problems; §83(b) does not cure §409A issues |
| Disqualifying disposition (ISO) | Sale before holding periods met converts to ordinary income on spread; §83(b) holding period start affects this |
| §422 ISO requirements | ISO must meet §422 (statutory option) requirements; early exercise permitted only if plan allows |
| Withholding NSO | NSO §83(b) income subject to withholding; ISO generally not subject to withholding even with §83(b) |
| QSBS §1202 coordination | §83(b) starts holding period for §1202 5-year QSBS requirement; early election critical for QSBS planning |
| Risk Element | Detail |
|---|---|
| Forfeiture after election §83(b)(1) | If property forfeited after §83(b) election, NO deduction allowed for amount previously included in income; only capital LOSS for amount PAID (less amount realized on forfeiture) |
| Prepaid tax with no liquidity | If grant FMV is substantial (not founder-formation $0), §83(b) requires paying ordinary tax on value before any liquidity - cash flow risk |
| Stock becomes worthless | Tax paid at grant on value that later evaporates; no recovery of tax paid (only capital loss for basis) |
| Irrevocability §83(b) | Election irrevocable except with IRS consent (only for mistake of fact, not change of mind) |
| Valuation risk | If IRS later determines grant FMV higher than reported, additional ordinary income plus penalties; 409A valuation important |
| When NOT to elect | High grant-date value with uncertain vesting; likely to leave before vesting; stock unlikely to appreciate; insufficient cash for tax |
| When TO elect | Low/zero grant value (founders); strong expected appreciation; intend to stay through vesting; want LTCG and QSBS holding period |
| 30-day miss | Cannot be cured; default §83(a) ordinary income at vesting applies; significant lost benefit for appreciating stock |
| State conformity | Most states conform; some require separate state election or have different rules; multistate service providers complex |
The single most catastrophic error. §83(b) MUST be filed within 30 days of transfer. No extensions, no §301.9100 relief, no exceptions. Practitioner must counsel client immediately on grant/early exercise. Certified mail with receipt for proof.
RSUs are NOT eligible - no property transferred at grant, only a promise to deliver shares at vesting. §83(b) requires actual property transfer. Practitioner advising §83(b) on RSUs misunderstands the mechanics; RSU holders cannot elect.
Options themselves generally are not "transferred property" for §83(b). Must EARLY EXERCISE first (if plan permits) to acquire restricted shares, then file §83(b) within 30 days of exercise. Practitioner filing on option grant is ineffective.
For early-exercised options, the 30-day clock runs from EXERCISE date, not option grant date. Practitioner counting from grant misses the deadline. Document exercise date precisely.
§83(b) on high-FMV grant requires paying ordinary tax immediately with no liquidity. Practitioner reflexively recommending §83(b) for late-stage employees with high 409A valuations creates cash crisis. Evaluate grant value and forfeiture risk.
If property forfeited after §83(b), NO deduction for income previously recognized §83(b)(1). Only capital loss for amount paid. Practitioner assuming forfeiture reverses the income is wrong; the recognized income is permanently lost.
§83(b) starts holding period at grant - critical for §1202 QSBS 5-year requirement and 1-year LTCG. Practitioner failing to elect delays QSBS clock to vesting, potentially losing years of qualified holding period.
§83(b) requires furnishing copy to employer/service recipient. Practitioner filing only with IRS may have defective election. Provide copy to company and retain proof.
§83(b) reports FMV at grant; if 409A valuation later challenged as too low, additional ordinary income plus penalties. Practitioner should ensure defensible 409A valuation supports the §83(b) reported value.
Early-exercised ISO + §83(b) with minimal spread reduces AMT preference. Practitioner not coordinating §83(b) with ISO AMT planning misses opportunity to minimize AMT on future appreciation.
Partnership profits interests (Rev. Proc. 93-27 / 2001-43) - protective §83(b) election common to confirm $0 value safe harbor. Practitioner omitting protective election for profits interest may face valuation dispute.
§83(b) election irrevocable except IRS consent for mistake of FACT (not change of mind). Practitioner advising client they can undo a §83(b) if stock drops is wrong; only mistake-of-fact revocation within strict limits.
Form 15620 (November 2024) is OPTIONAL standardized template. A compliant written statement remains acceptable. Practitioner believing Form 15620 mandatory may delay filing; either method works if required information included.
Employee §83(b) income subject to FICA and income tax withholding at grant. Practitioner not coordinating payroll withholding with company creates compliance gap; company must withhold on the §83(b) income.
Some states require separate state §83(b) election or have nonconforming rules. Practitioner filing only federal election may miss state requirement; multistate service providers need state-by-state analysis.
If vesting accelerates (acquisition, single/double trigger), §83(b) elector already recognized income at grant - no additional income on acceleration. Non-elector recognizes ordinary income on accelerated vesting at then-FMV. §83(b) advantage magnified by acceleration.
