5.5 Fund Taxation & Subchapter M

Internal Revenue Code Subchapter M prevents triple taxation of pooled investments by treating qualifying investment companies as conduit pipelines directly to shareholders.

Key FINRA Exam Takeaways

  • Subchapter M (Conduit / Pipeline Theory): If a fund distributes at least 90% of its Net Investment Income (NII), it pays NO corporate tax on the distributed portion.
  • Net Investment Income (NII) = (Dividends + Interest) - Operating Expenses. (Capital gains are EXCLUDED from NII).
  • Shareholders are taxed on distributions in the year received, even if automatically reinvested in additional shares.
  • Wash Sale Rule: Disallowing loss deductions if the same or 'substantially identical' security is purchased within 30 days before or after the sale (61-day window).

The 90% Conduit Rule

If a fund distributes 89% of its NII, it is taxed on 100% of its income as a regular C-corporation! If it distributes 92%, it only pays taxes on the retained 8%.

Wash Sale Rule Mechanics

If an investor sells XYZ at a $4,000 loss and repurchases XYZ 20 days later, the $4,000 loss is disallowed on current taxes and added to the cost basis of the newly acquired shares.
