QSBS Trust Stacking Faces Increased Regulatory Scrutiny
Founders, early employees, and venture investors in qualified small businesses must track emerging regulatory guidance, as heightened scrutiny of QSBS trust stacking could eliminate eligibility for the $15 million federal capital gains tax exclusion for affected holdings.
Enacted in 1993, Section 1202 of the Internal Revenue Code permits eligible shareholders of qualified small businesses to exclude up to $15 million in federal capital gains from the sale of qualifying stock, a benefit expanded by Congress in 2025. Regulators are now increasing scrutiny of 'trust stacking' strategies, where multiple trusts hold QSBS to multiply the available exclusion amount. Potential new rules or enforcement guidance could limit or disallow these stacking arrangements. Affected stakeholders should review existing QSBS holding structures with qualified tax counsel, confirm all statutory eligibility requirements are met, and monitor upcoming regulatory guidance to adjust holdings as needed to preserve tax benefits.
