Qualified Small Business Stock (QSBS): Could You Avoid Capital Gains Entirely?

Truforte Business Group - Brokers Blog

Most sellers have never heard of the QSBS capital gains exclusion, and for the ones who qualify, it’s one of the most significant tax breaks available anywhere in the federal tax code.

Quick Answer: QSBS Capital Gains Exclusion

The QSBS capital gains exclusion, under Section 1202, can exclude up to 100% of capital gains on the sale of qualifying C-corp stock, up to the greater of $10 million or 10x your original investment, if you’ve held the stock for at least 5 years and the company met specific requirements when the stock was issued.

QSBS capital gains exclusion requirements for business sellers

Who Can Qualify

The stock must be in a C-corporation (not an S-corp or LLC), acquired directly from the company (not purchased from another shareholder), held for at least 5 years, and the company generally needed gross assets under $50 million at the time the stock was issued.

What Kind of Business Qualifies

Most active operating businesses qualify, but the rules specifically exclude certain service businesses (though recent legislative changes have adjusted some of these limits and thresholds, so current-year specifics should always be confirmed with a CPA).

Why Most Sellers Miss This

QSBS eligibility is determined largely by decisions made at the time stock was originally issued, often years before a sale is contemplated, which means it’s frequently discovered too late to help, or missed entirely because no one checked.

How to Find Out If You Qualify

A CPA can review your company’s formation documents, stock issuance history, and financials against the QSBS requirements, see IRS Topic 409 on capital gains for the broader federal framework this fits into. Because QSBS requires a C-corp specifically, it’s worth reviewing alongside the S-Corp vs C-Corp decision if your structure is still flexible.

FAQ

Does QSBS apply to S-corps or LLCs? No, QSBS specifically requires C-corporation stock; S-corps and LLCs don’t qualify under current rules.

How much could this actually save me? For a qualifying seller, potentially the entire federal capital gains tax on the sale up to the applicable limit, a substantial amount for the right business.

When do I need to find out if I qualify? As early as possible, ideally when the company is formed or stock is issued, since eligibility is often locked in at that point, not at the time of sale.

Is this a new or obscure rule? It’s been part of the tax code for years but remains underused simply because many owners and even some advisors aren’t familiar with it.

Who should I ask to check this for me? A CPA or tax attorney familiar with QSBS specifically, this isn’t a routine tax return item most general preparers check by default.
