Kimberly Green | 2025-03-06

Qualified Small Business Stock (QSBS) represents one of the most powerful yet underutilized tax incentives available to investors and entrepreneurs in the United States today. Created under Section 1202 of the Internal Revenue Code, this provision allows for potentially complete tax exemption on capital gains when you sell shares of qualifying small businesses. If you invest in or found a qualifying company and hold those shares for at least five years, you could exclude up to 100% of your capital gains from federal taxes, up to the greater of $10 million or 10 times your original investment basis. This tax benefit was designed to encourage investment in small American businesses by reducing the tax burden on patient capital. Not every small business qualifies, however.
