TOPLINE:

The One Big Beautiful Bill (OBBB) relaxed certain rules regarding what counts as qualified small business stock (QSBS), allowing more QSBS sales by original-issue shareholders to qualify for capital gains exclusions.

BACKGROUND:

[if gte mso 9]> Normal 0 false false false false EN-US X-NONE X-NONE The tax code excludes from capital gains taxes certain sales of qualifying original-issue stock of smaller corporations. To qualify for the exclusion, certain conditions must be met. The stock of the small corporation must have been sold by an individual (or other non-corporate taxpayer) who acquired it as part of the original issue of the corporation’s stock (e.g., equity stakes of original investors or stock-based compensation of founding employees of a small corporation). At least 80% of the company’s assets must be used in the qualifying trade or business (but certain service businesses such as in health, law, or engineering where “the principal asset… is the reputation or skill… of its employees” do not qualify).

Prior to OBBB, the exclusion could only apply if the corporation had less than $50 million in gross assets at the time of the original stock issuance and if the stock was held for at least 5 years. The maximum exclusion (prior to OBBB) was the greater of $10 million or 10-times the taxpayer’s basis in the property.

BOTTOMLINE:

New corporations create jobs, pay wages, and provide competition and innovation that help drive down consumer prices. Congress should continue reducing the tax and regulatory burdens that stand in businesses’ way.
