Kimberly Green | 2025-03-07
The Qualified Small Business Stock (QSBS) exemption under Section 1202 of the Internal Revenue Code offers a powerful tax break for startup founders, early employees, and investors. If you meet certain QSBS eligibility criteria—including the 5-year holding period and other exclusion requirements—you could potentially exclude up to 100% of capital gains from federal taxes. In this guide, we’ll break down how to qualify for QSBS, who it applies to, and why understanding the requirements early can save you millions down the line. What Is QSBS? Qualified Small Business Stock (QSBS) refers to shares in a C-corporation that meet specific criteria outlined in Section 1202 of the Internal Revenue Code. When those shares are sold after being held for at least 5 years, a significant portion of the capital gains may be excluded from federal income tax. This tax benefit is designed to encourage investment in early-stage companies. Who Is Eligible for QSBS? To qualify for the QSBS tax exemption, both the stock and the shareholder must meet certain requirements. Here's a breakdown: QSBS Eligibility Criteria for the Stock: Issued by a U.S. C-Corporation (not an LLC or S-Corp) Gross assets <$50 million at the time of issuance Active business requirement: At least 80% of the company's assets must be used in an active trade or business (non-service-based in most cases) Original issuance: Shares must be acquired directly from the company, not from a secondary sale QSBS Requirements for Founders and Investors: Must be individuals (not entities) or certain trusts Must have received the shares in exchange for money, property, or services Must hold the stock for at least 5 years to qualify for full exclusion The QSBS 5-Year Rule The most important rule to qualify for the tax exemption is the 5-year holding period. Here’s what you need to know: The 5-year clock starts on the date the stock is issued to you Even if your company is acquired, you may be able to tack on holding periods if the acquirer provides stock in exchange If you sell before 5 years, you may qualify for a QSBS rollover under Section 1045, deferring gains instead of excluding them Pro tip: Keep clear records of your stock issuance date. It’s crucial for proving QSBS eligibility later. Section 1202 Exclusion Limits Depending on when the stock was acquired, you may be eligible for 50%, 75%, or 100% capital gains exclusion, up to $10 million or 10x your basis, whichever is greater.
