Quick Answer
The baseline maximum amount of capital gains—$10 million per issuer—that a single taxpayer can exclude under Section 1202 QSBS rules.
The $10M Exclusion Cap is the default ceiling on how much capital gain a single taxpayer can exclude from federal income tax when selling Qualified Small Business Stock under Section 1202. The actual limit is the greater of $10 million or 10 times the taxpayer's adjusted basis in the stock, calculated on a per-issuer basis. This means that if an investor's basis is relatively low (e.g., $100,000), the $10 million cap applies. But if the basis is high (e.g., $5 million), the 10x rule kicks in, allowing up to $50 million in exclusion. The cap is cumulative over the taxpayer's lifetime with respect to stock of each issuer, not per transaction.
In Practice
An angel invests $200,000 in a pre-seed round. Her 10x basis would only be $2 million, so the $10 million floor applies instead. When the company is acquired and her shares are worth $15 million, she can exclude $10 million of her $14.8 million gain. If she had invested $2 million at the same stage, her 10x cap would be $20 million, covering the entire gain.
Why It Matters
The $10M cap determines how much of a venture windfall is truly tax-free. Investors who understand this limit can strategically increase their basis through follow-on investments or use QSBS stacking strategies with trusts and family members to multiply the effective exclusion well beyond $10 million.
VC Beast Take
The $10M cap is where tax planning gets interesting. Smart investors structure multiple entities or time their investments across tax years to multiply this benefit. We've seen sophisticated family offices create complex structures to maximize QSBS benefits across multiple family members. The real opportunity isn't just hitting the cap once—it's architecting your entire portfolio strategy around it.
