The Qualified Small Business Stock (QSBS) exemption under Section 1202 of the Internal Revenue Code allows U.S. shareholders to exclude a substantial portion of capital gains when they sell qualified shares of a C‑corporation. In the right circumstances, the exclusion can reach $10 million per person or 10 times the shareholder’s original basis, effectively providing tax‑free gains on large exits.
Core requirements
| Requirement | Detail |
|---|---|
| Entity type | The issuing company must be a C‑corporation. LLCs, S‑corporations, or partnerships are ineligible. |
| Holding period | Shares must be held for at least five years before the sale. Short‑term flips do not qualify. |
| Eligible shareholder | The shareholder must be an individual, trust, or estate. Shares held by another corporation or partnership do not qualify. |
| Original issuance | Shares must be directly issued by the company (not purchased on a secondary market). This includes founder shares or shares bought in early‑stage financing. |
| Asset test | At the time of issuance, the corporation’s gross assets must be ≤ $50 million. The company can later grow to any size; the asset limit applies only at issuance. |
| Active business test | The corporation must be engaged in an active trade or business. Certain sectors (e.g., most financial services, hotels, farming, and some professional services) are excluded. Passive investment businesses do not qualify. |
How the exclusion is calculated
When the qualified shares are sold, the taxpayer may exclude the greater of:
- $10 million of the gain, or
- 10 × the shareholder’s adjusted basis in the stock (the amount originally invested).
Example: An entrepreneur who invested $2 million in qualified stock can exclude up to $20 million of gain (10 × $2 million). If the sale price is $50 million, the remaining $30 million is subject to regular capital‑gain tax (federal rate ≈ 23.8 % plus any applicable state tax).
Multiplying the benefit
The exclusion is per eligible shareholder, not per corporation. By placing shares into a family trust, each beneficiary can claim their own $10 million exemption. For a family of five (e.g., spouse and three children), up to $50 million of gain could be excluded.
Practical considerations
- State taxes: Some states conform to the federal QSBS exemption, while others do not. Structuring the sale to minimize state exposure can add further savings.
- C‑corp vs. LLC/S‑corp: Although LLCs and S‑corps offer pass‑through taxation, they cannot take advantage of QSBS. When a future sale is anticipated, forming a C‑corp early may be advantageous despite the double‑taxation risk on earnings.
- Documentation: Maintain clear records of the original purchase price, issuance date, and the corporation’s asset level at issuance to substantiate eligibility.
- Timing: The five‑year holding period must be met before the sale; any earlier disposition disqualifies the exemption.
- Business type: Verify that the company’s activities fall within the permitted “active business” categories. Excluded industries cannot benefit from QSBS regardless of other criteria.
Decision checklist for entrepreneurs
-
Will the company be a C‑corp?
If a potential exit is part of the business plan, incorporate as a C‑corp from the start. -
Can the company meet the $50 M asset test at issuance?
Early‑stage startups typically qualify; larger existing firms usually do not. -
Is the business an active trade?
Review the IRS list of excluded sectors to ensure eligibility. -
Do you plan to hold shares ≥ 5 years?
Align equity compensation and investor timelines with the holding requirement. -
Can you structure ownership through trusts or estates?
Consider family trusts to multiply the per‑person exemption.
When these conditions align, the QSBS exemption can transform a multi‑million‑dollar exit into a largely tax‑free event, dramatically increasing net proceeds for founders, early investors, and their families.
