If you're a founder, startup employee, or early investor planning to sell your stake in a C corporation, there’s a powerful tax provision you absolutely need to know about: IRS Section 1202, also known as the Qualified Small Business Stock (QSBS) exclusion.
This little-known section of the tax code could potentially save you millions in capital gains taxes when you sell qualifying stock.
What Is IRS Section 1202?
Section 1202 allows eligible shareholders to exclude up to 100% of their capital gains from federal taxation when selling qualifying small business stock.
That’s right, in some cases, your gain from selling startup stock could be completely tax-free at the federal level.
Why It Matters: The Numbers Are Significant
Under Section 1202, eligible shareholders can exclude:
- Up to $10 million in capital gains (or $15 million for stock acquired after July 4, 2025), or
- 10x your initial investment, whichever is greater.
Considering that federal capital gains taxes can reach 23.8% (20% capital gains + 3.8% net investment income tax), the savings are enormous.
Example:
A $10 million gain could translate into $2.38 million in tax savings.
Do You Qualify?
You may qualify for the QSBS exclusion if:
- You own stock in a U.S. C corporation
- The company had less than $50 million in assets when you acquired your shares
- You received the stock directly from the company (not via a secondary purchase)
- The company operates in a qualified industry (note: service businesses like consulting, law, finance, and hospitality are generally excluded)
- You’ve held the stock for at least 5 years
Should You Explore Section 1202?
If you’re planning a sale or exit in the next few years — or if your holding period will soon reach five years, you should absolutely look into this.
Section 1202 could be particularly beneficial if:
- You founded or invested early in a startup
- Your company is structured as a C corporation (or could be converted to one)
- Your potential gains are significant
Timing and Key Considerations
Timing is everything when it comes to Section 1202. Here are a few important details to keep in mind:
- The 5-year holding period is critical. Plan ahead
- Stock acquired after September 27, 2010, qualifies for the full 100% exclusion
- If you convert from an LLC or S-corp to a C-corp, the 5-year clock starts at conversion
Next Steps: Plan Early, Save Big
Section 1202 is complex, and not every company or shareholder will qualify. However, the potential tax savings make it well worth exploring early, ideally as part of your exit or liquidity event planning.
Here’s what to do next:
- Review your stock acquisition dates and company structure
- Consult with a tax advisor who specializes in QSBS planning
- Plan early, don’t wait until you’re ready to sell
