QSBS (Section 1202): The $10 Million Tax-Free Exit

By Team BMT Jan 30, 2026

💡 Executive Summary

  • Problem: You founded a startup or invested early. When you exit for $10M+, federal capital gains tax (23.8%) eats away ~$2.4M of your reward.
  • Solution: Ensure your shares qualify as Qualified Small Business Stock (QSBS) under IRC Section 1202.
  • Result: You can exclude 100% of the gain from federal taxes, up to $10M or 10x your basis (whichever is greater). It is the closest thing to a “Free Lunch.”
⚠️ THE C-CORP TRAP
QSBS only applies to Domestic C-Corporations. If you held your shares in an LLC or S-Corp at issuance, you generally disqualify yourself. This is the #1 reason why VC-backed startups are C-Corps. Also, the company’s gross assets must be under $50M at the time you acquired the stock.

For Founders and Angel Investors (Tier L1/L2), QSBS is non-negotiable. It rewards risk-taking in small businesses by eliminating the tax bill upon success. If you structure it right, a $10 million exit puts $10 million in your pocket.

🧐 Core Mechanic: “Stacking”
Is your exit bigger than $10M? You can “stack” exemptions.
• Gift shares to Irrevocable Trusts (e.g., for kids) before the sale.
• Each trust gets its own separate $10M exemption.
• Result: 3 Trusts + You = $40M Tax-Free.

“QSBS is the government’s way of apologizing for the risk you took. Don’t let a structuring error (like forming an LLC) reject that apology.”
