Chapter 16

Qualified Small Business Stock (QSBS)

Section 1202 of the Internal Revenue Code contains one of the most remarkable provisions ever written into tax law. For the right investor in the right situation, it can eliminate federal capital gains tax on millions of dollars of investment gains — completely legally.

If you hold qualified small business stock for more than five years, you may exclude up to $10 million in capital gains from federal income tax.

Zero tax on $10 million in gains.

The Requirements

For the Company:

Must be a C-Corporation (LLCs, S-Corps, and partnerships do not qualify)
Must be domestic (U.S.-based)
Gross assets must not exceed $50 million at the time of issuance
Must be an active business in a qualifying industry
Excluded industries: services (law, health, finance, consulting, athletics), hospitality, financial services

For the Investor:

Must be an original purchaser (not secondary market)
Must acquire stock in exchange for money, property, or services (not by purchase from another shareholder)
Must hold for more than 5 years

The Exclusion

Up to $10 million per taxpayer per qualifying company, or
10 times the adjusted basis of the stock (whichever is greater)

For founders and early investors, the 10x basis rule can dramatically exceed $10 million.

A Life-Changing Example

Entrepreneur invests $500,000 founding a C-Corp startup Five years later, company is acquired for $11,000,000 Gain: $10,500,000 Federal capital gains tax without QSBS (23.8%): ~$2,499,000 Federal capital gains tax with QSBS: $0 Tax savings: ~$2,499,000

The Stacking and Multiplication Strategies

Spouse Stacking: Each spouse can independently claim the $10M exclusion on the same investment — potentially $20M per couple per company.

Multiple Companies: The exclusion applies per company. An investor or entrepreneur holding QSBS in five qualifying companies has $50M+ in potential exclusion.

Gifting: QSBS can be gifted to family members (trusts, children) who each receive their own exclusion — potentially multiplying the benefit across generations.

QSBS for Founders

Entrepreneurs who form a C-Corporation may qualify for QSBS on the sale of their own company. This is potentially the most valuable application of Section 1202 — a founder who builds and sells their company could exclude $10 million or more in gains from federal tax entirely.

This is one of the most compelling arguments for choosing C-Corporation structure at formation.

State Tax Considerations

Some states — including California and New York — do not conform to Section 1202. State taxes may still apply even when federal gains are fully excluded.
