New and Improved Tax Treatment for Qualified Small Business Stock

The One Big Beautiful Bill Act of 2025 (OBBBA) made the tax advantages of founding and investing in certain types of small businesses even more generous. Shareholders can exclude from income up to 100% of the gain realized from the sale of qualified small business stock (QSBS) if they hold the shares for more than five years (up to a specific dollar cap). This powerful incentive is intended to help startups and other small businesses raise capital to fund their growth.



To qualify, the stock must be issued by an active U.S. C corporation with gross assets (cash plus the adjusted basis of property) that don’t exceed a certain amount, among other requirements. Some types of businesses are ineligible, including professional services, financial and investment services, banking, leasing, insurance, health care, hospitality, and mining.

Expanded tax benefits

For qualified small business stock issued after July 4, 2025, shareholders may benefit from some significant changes, including:


Because businesses are defined as small based on a snapshot of the assets on their balance sheets, asset-light businesses like technology companies may qualify for QSBS treatment even if they have much higher valuations.


Who stands to gain?

This tax break applies only to original issue stock acquired from the company, not to stock purchased on the secondary market. Shares may be acquired in exchange for money, property, or compensation. In fact, qualifying businesses often use their stock as an incentive to attract and retain key employees. However, if QSBS is received as part of a deferred compensation plan, the holding period will not commence until the value of the stock is included in the employee’s income. Because businesses are defined as small based on a snapshot of the assets on their balance sheets, asset-light businesses like technology companies may qualify for QSBS treatment even if they have much higher valuations.

When a business is involved in a qualifying activity and a nonqualifying activity — think technology and financial services (fintech) or manufacturing and health care — it can be difficult to determine whether it qualifies as QSBS or not. Moreover, not all states recognize QSBS tax treatment, and those that do may not have the same requirements. Be sure to consult a tax and/or legal professional who is familiar with the law in your state.
