The IRC 83(b) election is a one-page filing that can save startup founders and early employees hundreds of thousands of dollars in taxes, and missing the 30-day deadline is irreversible. Under IRC 83(a), when property (including stock) is transferred in connection with the performance of services and the property is subject to a “substantial risk of forfeiture” (typically a vesting schedule), the recipient recognizes ordinary income when the property vests, not when it is received. The amount of income equals the fair market value of the property at the time of vesting, minus any amount the recipient paid for it. For startup stock that increases in value dramatically between the grant date and the vesting dates, this creates enormous ordinary income recognition at rates up to 37%. The IRC 83(b) election allows the recipient to accelerate income recognition to the grant date, when the stock’s value is typically minimal, and convert all subsequent appreciation to capital gain. The election must be filed with the IRS (mailed or faxed) within 30 calendar days of the date the stock is transferred, and a copy must be included with the taxpayer’s federal income tax return for that year.

✓Key takeaway

IRC 83(b) election requirements:

Requirement	Details
Filing deadline	30 calendar days from the date of stock transfer (NOT vesting)
Filed with	IRS Service Center where taxpayer files their return
Copy to employer	Required
Attached to tax return	Copy must be attached to the year’s income tax return
Can it be revoked?	No (only with IRS consent, which is rarely granted)
Late filing accepted?	No. The 30-day deadline is absolute. No extensions, no exceptions.
Form	No official IRS form; a written statement with required information

Required information in the 83(b) election statement:

Item	Details
Taxpayer name, address, SSN
Description of property	Number of shares, class of stock
Date of transfer	Date stock was received
Nature of restriction	Vesting schedule description
Fair market value at transfer	FMV of stock on the grant date
Amount paid for stock	Price paid by the recipient
Taxable income recognized	FMV minus amount paid
Statement that election is made under IRC 83(b)

Who should file an 83(b) election:

Scenario	File 83(b)?	Why
Startup founder receiving stock at incorporation ($0.001/share)	Almost always yes	Current value is negligible; future appreciation = capital gain
Early employee receiving restricted stock at low valuation	Usually yes	Same logic as founder
Employee at a mature company receiving RSUs (restricted stock units)	No (cannot file 83(b) on RSUs)	RSUs are promises, not property; IRC 83(b) requires a property transfer
Employee receiving restricted stock at fair market value	Depends	If stock will appreciate substantially, yes; but no tax benefit if stock does not appreciate
Anyone who might leave before vesting	Carefully evaluate	Forfeited stock = no deduction for the 83(b) income already recognized

How does the 83(b) election save taxes?

Hypothetical example

Round numbers. A founder receives 1,000,000 shares of restricted stock at a startup, subject to 4-year vesting (25% per year). The stock is purchased at $0.001 per share.

Without 83(b) election (taxed as stock vests):

Year	Shares Vesting	FMV/Share at Vesting	Ordinary Income	Tax (37%)
Year 1	250,000	$1.00	$250,750	$92,408
Year 2	250,000	$5.00	$1,249,750	$462,408
Year 3	250,000	$10.00	$2,499,750	$924,908
Year 4	250,000	$20.00	$4,999,750	$1,849,908
Total ordinary income			$8,999,000	$3,329,632

Later sale at $30/share:

Item	Amount
Sale price (1,000,000 x $30)	$30,000,000
Basis (FMV at vesting, weighted avg ~$9/share)	$9,000,000
Capital gain	$21,000,000
Capital gains tax (23.8%)	$4,998,000
Total tax (ordinary + capital gains)	$8,327,632

With 83(b) election (taxed at grant):

Event	Amount
Income at grant (1,000,000 x ($0.001 - $0.001))	$0 (paid FMV)
Tax at grant	$0
Holding period starts	Grant date

Later sale at $30/share (after 4 years, long-term capital gains):

Item	Amount
Sale price (1,000,000 x $30)	$30,000,000
Basis ($0.001 x 1,000,000)	$1,000
Long-term capital gain	$29,999,000
Capital gains tax (23.8%)	$7,139,762
Total tax	$7,139,762

Tax savings from 83(b) election: $1,187,870

The savings come from two sources: (1) avoiding ordinary income tax rates (37%) on the appreciation during the vesting period, and (2) starting the long-term capital gains holding period at the grant date rather than each vesting date.

Scenario comparison at different exit valuations:

Exit Price/Share	Without 83(b) Total Tax	With 83(b) Total Tax	Savings
$5 (modest exit)	$1,092,000	$1,189,762	($97,762) (83(b) costs more if stock barely appreciates)
$10	$2,717,000	$2,379,762	$337,238
$30	$8,327,632	$7,139,762	$1,187,870
$50	$13,267,632	$11,899,762	$1,367,870
$0 (company fails)	$0 (no vesting = no income)	$0 (but no loss deduction for 83(b) income, which was $0)	$0

The forfeiture risk:

Scenario	Without 83(b)	With 83(b)
Founder leaves after Year 1 (750K shares forfeited)	No tax on unvested shares (never recognized)	No deduction for income recognized on forfeited shares
If 83(b) income was $0 (bought at FMV)	N/A	No harm (recognized $0, forfeited, lost $0 tax)
If 83(b) income was $100,000 (stock had value above price paid)	N/A	Paid $37,000 in tax on income that was effectively returned; no deduction

This is why the 83(b) election is most valuable when the stock’s current value is very low: the income recognized at grant is minimal, so the forfeiture risk is also minimal.

QSBS interaction (IRC 1202):

Item	Details
QSBS eligibility	Stock acquired at original issuance from a qualified small business
83(b) election + QSBS	The holding period for QSBS starts at the grant date (with 83(b)) rather than vesting dates
5-year holding requirement	Easier to meet when holding period starts at grant
Exclusion	Up to $10 million or 10x basis, whichever is greater, excluded from federal tax
Combined benefit	83(b) + QSBS can result in $0 federal tax on up to $10 million of gain

Common mistakes:

Mistake	Consequence
Missing the 30-day deadline	Cannot file late; stuck with IRC 83(a) treatment
Not sending copy to employer	May not invalidate election, but creates compliance risk
Filing on RSUs (not restricted stock)	RSUs are not eligible for 83(b); election is void
Not attaching copy to tax return	May not invalidate, but IRS may challenge
Confusing stock options with restricted stock	83(b) applies to restricted stock; for stock options, it applies only to stock received upon exercise of an early-exercise option
