Business Entity Choice Can Impact Millions in Sale Proceeds

The decision of how to structure a business entity has a significant impact on future growth and profitability, extending beyond mere administrative compliance. For many founders, understanding the implications of choosing between entities like LLCs, S-corporations, or C-corporations is crucial for long-term success.

A key driver for this decision is the potential benefit of Qualified Small Business Stock (QSBS). This provision allows owners to potentially exclude millions of dollars in capital gains from federal income tax upon selling their company. However, QSBS has specific requirements, and selecting the wrong entity structure from the outset can disqualify a business from ever benefiting from it.

To qualify for QSBS, a company must be structured as a domestic C-corporation at the time the stock is issued. Businesses formed as LLCs or S-corporations do not begin the QSBS clock until they convert to or issue C-corporation stock. Recent changes, effective July 4, 2025, introduce tiered benefits: a three-year holding period offers a 50% exclusion, four years yields 75%, and five years provides a full 100% exclusion. Prior to that date, a five-year holding period was generally required.

Eligibility also depends on the company's size at the time of stock issuance, with aggregate gross assets capped at $75 million (up from $50 million previously) as of July 4, 2025. Furthermore, certain industries, including healthcare, law, accounting, consulting, financial services, and hospitality, are excluded from QSBS. The maximum exclusion is also capped, generally at the greater of $15 million or ten times the stock's basis.
