The Recent Expansion of the QSBS Rules Creates New Opportunities for Venture Capital Funds and Their Investors

The One Big Beautiful Bill Act, enacted on July 4, 2025, modernizes and expands the already favorable tax treatment that applies to investments in qualified small business stock (QSBS).

The expansion of the QSBS rules under the Act should be a welcome development for venture capital funds and their investors.
