$10M Exclusion Cap
Last updated
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.
