What Is Qualified Small Business Stock (QSBS)?
Section 1202 of the Internal Revenue Code provides a federal capital gains exclusion for stock in qualified small businesses. Section 1202 runs two tracks, and the date the stock was acquired decides which applies. Stock acquired after July 4, 2025: the exclusion is 50% at a three-year hold, 75% at four years and 100% at five years, capped at the greater of $15 million (indexed for inflation from 2027) or 10 times the adjusted basis. Stock acquired on or before July 4, 2025: the original rules continue -- a 100% exclusion, but only after more than five years, capped at the greater of $10 million or 10 times basis (the 100% figure applies to stock acquired after September 27, 2010). The two-track structure was created by Section 70431 of the One Big Beautiful Bill Act (Public Law 119-21).
As discussed in "Billionaire Wealth Strategies" (Jim Dew, 2024), Chapter 9, QSBS is one of the primary tools in the "E" (Eliminate) component of the DEAPR framework, representing one of the few provisions in the Internal Revenue Code that can permanently eliminate a capital gains tax liability rather than merely defer it.
How Does QSBS Work?
To qualify under IRC Section 1202, the stock must satisfy several requirements established by Congress to target active small business investment:
C-Corporation requirement: The company must be organized as a domestic C-corporation at the time the stock is issued. S-corporation, partnership, and LLC stock does not qualify under IRC Section 1202(d).
Active business test: Under IRC Section 1202(e), at least 80% of the corporation's assets must be used in the active conduct of one or more qualified trades or businesses. Excluded industries include professional services (health, law, engineering, accounting, consulting, financial services, performing arts, athletics), banking, insurance, financing, leasing, farming, mining, and hotel/restaurant/similar businesses.
Gross asset limitation: Under IRC Section 1202(d), the corporation's aggregate gross assets cannot exceed $75 million at any time before and immediately after the stock issuance for stock issued after July 4, 2025, or $50 million for stock issued on or before that date. The $75 million figure is indexed for inflation from 2027. Gross assets include cash and the adjusted basis of other property.
Original issuance: The stock must be acquired at original issuance directly from the corporation in exchange for money, property (other than stock), or services. Stock purchased on a secondary market does not qualify.
Holding period: For stock acquired after July 4, 2025, three years earns a 50% exclusion, four years 75% and five years 100%. For stock acquired on or before that date the requirement is a flat five years with no partial exclusion. The holding period begins on the date the stock is issued to the taxpayer.
The exclusion under IRC Section 1202 is per-shareholder, per-company. Multiple shareholders in the same company each have their own cap. Under IRC Section 1202(h), stock gifted to family members retains its QSBS status and holding period, and trusts that hold QSBS can claim their own separate exclusion, effectively multiplying the total excludable gain across family members and entities.
When Do Entrepreneurs Use QSBS?
Startup founders plan entity structure from inception as a C-corporation to establish QSBS eligibility from day one. The five-year clock begins at stock issuance, so early C-corporation formation maximizes the time available to meet the holding period before a potential exit.
Pre-exit planning may involve converting from an S-corporation or LLC to a C-corporation at least five years before a planned sale. The conversion restarts the holding period under IRC Section 1202, so the timing decision is critical. Stock issued in the conversion must meet all QSBS requirements independently.
Family wealth multiplication uses gifting strategies under IRC Section 1202(h) to transfer QSBS shares to family members and trusts before the sale. Each recipient has their own per-issuer cap. A founder who gifts shares to a spouse, children, and trusts can potentially exclude $30 million to $50 million or more in total gains, depending on the number of eligible recipients.
Angel investors who acquire original-issue stock in qualifying small businesses can use the QSBS exclusion on their investment gains, provided all IRC Section 1202 requirements are met at the time of issuance and throughout the holding period.
How Does Dew Wealth Approach QSBS Planning?
QSBS may represent $2 million to $3.7 million in potential federal tax savings on a $10 million gain, depending on whether state taxes conform to the federal exclusion. At the combined federal rate of 23.8% (20% long-term capital gains plus 3.8% NIIT under IRC Section 1411), the federal savings alone on $10 million is approximately $2.38 million.
Many entrepreneurs miss the QSBS opportunity because their business is structured as an S-corporation or LLC rather than a C-corporation, or because they were not aware of the holding-period requirement until after a sale was imminent. The entity structure decision must be made years in advance.
The Fractional Family Office® evaluates QSBS eligibility during initial planning, monitors the gross asset threshold, verifies the active business test under IRC Section 1202(e), and coordinates entity structure decisions with the tax advisor and corporate attorney to preserve qualification.
QSBS has limitations beyond the industry exclusions. The gross asset ceiling at issuance disqualifies larger companies. The holding period creates illiquidity risk. State conformity varies: some states (California, for example) do not conform to the federal Section 1202 exclusion, meaning state capital gains tax still applies. The exclusion may be subject to legislative change, and there is no guarantee that the 100% exclusion rate will remain in effect for future tax years.
