Incorporating Your Life: The Family Management Company (FMC)

Executive Summary

  • The TCJA Problem: Before 2017, individuals could deduct investment expenses (Section 212) on their tax returns. The Tax Cuts and Jobs Act eliminated this. Now, if you pay $100k for financial data or advice, it is considered a personal expense—0% deductible.
  • The FMC Solution: You establish a **Family Management Company** (usually a C-Corp or LLC). This entity provides “management services” to your family’s trusts and investment entities.
  • The Mechanism:
    1. Family Trusts pay a **Management Fee** to the FMC.
    2. The FMC uses this revenue to pay for **Staff (Salaries), Office Rent, IT/Software, and Health Insurance**.
    3. Because the FMC is a “Trade or Business” (Section 162), these expenses are **fully deductible** against its revenue.

The “Lender” Case Precedent

Legal Guardrail: The US Tax Court case Lender Management, LLC v. Commissioner established that a family office CAN be a business, but only if it operates for **profit**.
👉 Rule: Your FMC cannot just break even or run at a loss forever. It must charge a market-rate fee (e.g., 0.5% of AUM) and aim to show a net profit to prove it is a genuine commercial enterprise.
