QSBS: The $10M+ Tax Break Every Founder Should Know

If you're building a C Corporation, there's a tax benefit that could save you millions: Qualified Small Business Stock (QSBS) under Section 1202.

Done correctly, QSBS allows you to exclude up to $10 million (or 10x your basis) in capital gains from federal taxes when you sell your company or go public.

What is QSBS?

QSBS is a tax incentive designed to encourage investment in small businesses. If your stock qualifies, you can exclude up to 100% of your capital gains from federal taxation.

Example: You start a company with $100K. Five years later you sell it for $15M. With QSBS, you could owe $0 in federal capital gains tax on that $14.9M gain.

QSBS Requirements

Your stock must meet ALL of these criteria:

1. C Corporation

• Must be a C Corp when stock is issued AND held
• LLCs and S Corps don't qualify (but you can convert)

2. Qualified Business

• Gross assets <$50M when stock is issued
• Must be an active business (not passive investment)
• Certain industries excluded (finance, hospitality, consulting, etc.)

3. Original Issuance

• You must acquire stock directly from the company
• No buying from other shareholders

4. Five-Year Holding Period

• Must hold stock for 5+ years before sale
• Clock starts from date of issuance

5. Active Business

• 80%+ of assets must be used in active business operations

Common QSBS Mistakes

Starting as an LLC - Many founders start as an LLC for simplicity, then convert to C Corp later. This works, but you lose QSBS time.

Waiting to structure - QSBS clock starts when stock is issued. Every day delayed is a day longer until you can exit tax-free.

Exceeding $50M - Once you cross $50M in assets, new stock issuances don't qualify. Early employees might not get QSBS.

Wrong business activity - Consulting, financial services, hospitality, farming, and other industries don't qualify.

Maximizing QSBS Benefits

Stack with family members - Spouse and kids can each have their own $10M exclusion through proper planning.

Multiple companies - The limit is per-company, not per-person. Serial founders can use QSBS multiple times.

Plan from day one - Structure correctly at formation. Retrofitting is harder and costs you time.

State Tax Considerations

QSBS is a federal benefit. Some states (like California) don't honor it, while others (like Florida and Texas with no state income tax) make it even more powerful.
