Qualifying C corporations have long offered tax benefits to their investors under Section 1202 of the Internal Revenue Code, but fluctuations in the benefit and the capital gains tax have limited its use. Tax reform under the law commonly known as the Tax Cuts and Jobs Act (TCJA) may make the Qualified Small Business Stock (QSBS) Exemption in Section 1202 benefit more widespread and appealing for small businesses. To take advantage of the QSBS Exemption, both businesses and their investors need to be aware of how it works, its potential limitations, and the planning opportunities available.
