Capital Gains Exemption Strategies Using Qualified Small Business Stock (QSBS)

If you're a founder, angel investor, or early-stage startup employee, the Qualified Small Business Stock (QSBS) exemption under Section 1202 of the U.S. tax code might be one of the most powerful tax strategies available to you.

With the right planning, you could exclude up to 100% of capital gains on stock sales—potentially saving millions in taxes.

In this post, we explore how QSBS works, who qualifies, and how to structure equity to unlock its benefits.

What Is Qualified Small Business Stock (QSBS)?

QSBS refers to shares in a C-corporation that meet certain IRS criteria under Section 1202 of the tax code.

If eligible, gains from the sale of QSBS held for more than five years can be excluded from federal capital gains tax—up to $10 million or 10 times the original investment.

It applies to certain startups in tech, manufacturing, biotech, and more (but not to services like law or finance).

Who Is Eligible for the Exemption?

✅ The company must be a domestic C-corporation

✅ Shares must be issued directly (not bought on the secondary market)

✅ Gross assets of the company must be under $50 million at the time of issuance

✅ The company must use at least 80% of assets in an active trade or business

How Much Can Be Exempted?

➤ 50%, 75%, or 100% of capital gains may be excluded depending on the acquisition date:

✔️ 100% for shares acquired after Sept 27, 2010

✔️ 75% for shares acquired between Feb 18, 2009 and Sept 27, 2010

✔️ 50% for earlier acquisitions

➤ Exemption limit: $10 million or 10x your basis (whichever is greater)

Advanced QSBS Planning Tips

✔️ Stack exemptions by gifting shares to family members or non-grantor trusts

✔️ Time your exit to meet the 5-year holding period

✔️ Confirm QSBS eligibility annually with corporate counsel

✔️ Use Section 1045 rollover if you sell QSBS before 5 years and reinvest

Compliance Risks and IRS Scrutiny

✘ If the company changes entity type or exceeds $50M post-issuance, future gains may not qualify

✘ Selling before 5 years = full taxation (unless rolled over)

✘ You must maintain detailed records of share issuance, value, and use of funds
