该策略已从矽谷新创公司扩展至全国各地的传统企业，其地理范围延伸了数千公里（thousands of miles）。这一趋势与巨大的人口结构转变相吻合：预计在未来十年内退休的婴儿潮世代拥有约600万家美国企业。据估计，这些企业主中每六人就有一人（16.7%）会出售其公司，这可能会产生高达5兆美元的交易收益。像 Jim Byron 这样的企业主正积极将他们的公司从S型企业转为C型企业，以吸引寻求 QSBS 优惠的投资人。例如，Jim Byron 预计他公司去年低于500万美元的营收将在2026年增长约30%。同样地，年长的企业主正日益将 QSBS 视为其家庭传承与退出计划的关键组成部分。
然而，随著 QSBS 的日益普及，由于诸如「堆叠」（stacking）等激进的优化策略，它已引起了监管审查。利用这种技术，创办人可以将股份分配给多个家庭信托——例如为四个孩子设立四个信托——除了创办人个人1,500万美元的免税额外，还能为高达6,000万美元的收益提供避税保护。Trump 政府以及像 Kenneth Kies 这样的财政部官员已经警告，利用多个类似的信托来加倍节税可能违反国税局禁止滥用信托堆叠的规定。尽管民主党在2021年曾提议缩减该免税额以限制富人避税，但该条款目前仍保持不变，不过随著家庭试图将其未税收益最大化，该条款仍受到持续的监管审查。
Section 1202 of the US tax code, concerning "qualified small business stock" (QSBS), has become a prominent tax-avoidance strategy. Originally designed for companies with gross assets under $75 million, it allows investors who hold shares for five years to exclude a significant portion of capital gains from federal taxes. Under the 2025 tax law signed by Donald Trump, the individual exemption cap was raised by 50% from $10 million to $15 million (or ten times the initial stake), and the holding period was relaxed to three years for partial benefits. The US Treasury estimates this tax break will cost $67 billion over the next decade. Historically, from 2012 to 2022, QSBS enabled over $140 billion in capital gains to escape taxation, with nearly 75% of these exclusions benefiting individuals earning more than $1 million annually. Although it requires a C-corporation structure, which accounts for less than 5% of US businesses, its popularity continues to rise.
The strategy has expanded thousands of miles from Silicon Valley startups to mainstream businesses nationwide. This trend aligns with a massive demographic shift: approximately 6 million US businesses are owned by baby boomers retiring in the next decade. It is estimated that one in six (16.7%) of these owners will sell their companies, potentially generating up to $5 trillion in transaction proceeds. Business owners like Jim Byron are actively converting their firms from S-corporations to C-corporations to attract investors seeking QSBS benefits. For example, Jim Byron expects his company's revenue of under $5 million to grow by 30% in 2026. Similarly, older business owners are increasingly viewing QSBS as a critical component of their family succession and exit planning.
However, the growing popularity of QSBS has attracted scrutiny due to aggressive optimization strategies like "stacking." Using this technique, a founder can distribute shares across multiple family trusts—such as four trusts for four children—to shield up to $60 million in gains, in addition to their personal $15 million exemption. The Trump administration and Treasury officials like Kenneth Kies have warned that utilizing multiple similar trusts to multiply tax savings may violate IRS rules against abusive stacking. While Democrats proposed scaling back the exemption in 2021 to limit tax avoidance by the wealthy, the provision remains intact, though subject to ongoing regulatory examination as families attempt to maximize their untaxed returns.
