QSBS Exclusion
Last updated
Quick Answer
A federal tax benefit allowing investors to exclude up to 100% of capital gains from the sale of qualified small business stock held for at least five years.
The QSBS Exclusion, codified under Section 1202 of the Internal Revenue Code, allows investors to exclude a significant portion—or even all—of the capital gains realized from selling qualified small business stock. To qualify, the stock must be in a domestic C-corporation with gross assets under $50 million at the time of issuance, and the investor must hold the stock for at least five years. Depending on when the stock was acquired, the exclusion can be 50%, 75%, or 100% of the gain, up to the greater of $10 million or 10x the investor's basis. This provision is one of the most powerful tax incentives in venture capital.
In Practice
An angel investor purchases $500,000 of stock in an early-stage C-corp in 2020. By 2026, the company is acquired and her shares are worth $12 million. Because the stock qualifies as QSBS and she held it for over five years, she excludes up to $10 million of the $11.5 million gain from federal taxes, saving roughly $2.3 million in capital gains tax.
Why It Matters
For founders and early investors, the QSBS exclusion can be the single largest tax benefit available. It effectively makes early-stage venture investing tax-free up to substantial limits, which is why experienced VCs and angels structure deals specifically to preserve QSBS eligibility.
