QSBS Red Flags: Excluded Trades & The 80% Test

QSBS Red Flags: Excluded Trades & The 80% Test

A critical audit of the “Qualified Trade” definition, working capital limits, and the disqualifying redemption traps.

Dec 23, 2025 Code Authority: Team BMT RISK ALERT

Executive Summary

  • Excluded Services: Section 1202(e)(3) explicitly disqualifies health, law, consulting, and financial services. OBBBA reinforces this ban.
  • The 80% Rule: At least 80% of assets must be used in the active conduct of business. Hoarding cash for >2 years can kill eligibility.
  • Redemption Trap: Buying back significant stock from shareholders within a 2-year window can disqualify all issued stock.

The “Reputation” Clause

Any business where the principal asset is the reputation or skill of its employees (e.g., a celebrity-backed brand or boutique consulting) is automatically excluded. This is the #1 audit trigger for service-heavy startups.
