IRC Section 1202: The $10 Million 0% Capital Gains Exemption
The statutory blueprint for eliminating up to 100% of federal capital gains tax on early-stage startup stock sales.
01. What is Qualified Small Business Stock (QSBS)?
Enacted under Internal Revenue Code (IRC) Section 1202, Qualified Small Business Stock (QSBS) provides startup founders, early employees, angel investors, and venture capitalists with an extraordinary tax incentive: the ability to exclude up to $10,000,000 or 10 times your adjusted cost basis (whichever is greater) from federal capital gains taxes.
02. The 5 Core Statutory Qualifications
To qualify for the 100% federal capital gains exclusion, the stock and the issuing company must meet all five statutory tests:
- Domestic C-Corporation: The stock must be issued by a US domestic C-Corporation (LLCs and S-Corps do not qualify, though LLC units can qualify post-conversion).
- Original Issuance: You must acquire the shares directly from the company in exchange for money, property, or services (secondary market stock purchases are disqualified).
- $50 Million Gross Asset Test: The company's aggregate gross assets must not exceed $50,000,000 immediately before and after the stock is issued.
- Active Business Test: At least 80% of corporate assets must be actively used in a qualified trade or business (technology, manufacturing, software). Ineligible sectors include professional services (law, health, accounting), banking, farming, and hospitality.
- 5-Year Holding Period: You must hold the stock for at least 5 continuous years before selling.
03. The "10x Basis" Multiplier for Large Capital Injections
While the baseline exclusion is $10 Million, investors who invest significant capital can exclude up to 10 times their original cash investment. For example, if an angel investor contributes $3,000,000 in early seed capital, their potential QSBS capital gains exclusion is $30,000,000 (10 × $3M) tax-free!
04. Frequently Asked Questions (FAQ)
Important distinction: California does NOT conform to federal Section 1202, meaning California state capital gains tax (up to 13.3%) will still apply. New York and most other states conform fully to federal QSBS exclusions.
Under IRC Section 1045, if you have held QSBS for at least 6 months, you can roll your sale proceeds tax-free into a new qualified small business stock within 60 days to preserve your holding period!
