Overview

What this guide covers

Most SMSF trustees are unaware that their fund can hold shares in an actively trading company, provided the ownership structure is set up correctly. When two genuinely unrelated SMSFs each hold 50% of a trading company, neither fund controls it, which means the company falls outside the related party rules. This single fact unlocks a structure that combines company-level asset protection with some of the most tax-efficient investment returns available in the Australian superannuation system.

KEY TAKEAWAYS

What you will learn

✔  Why the "related party" question is the most critical compliance issue — and how a genuine 50/50 unrelated split resolves it

✔  Why the in-house asset 5% rule does not apply to this structure, and why Regulation 13.22C is irrelevant for trading companies

✔  How franking credits flow from the company to your SMSF, producing refunds in accumulation phase and full cash refunds in pension phase

✔  What a shareholders agreement must cover in a 50/50 structure, including deadlock resolution and dividend policy

✔  The 10-point compliance checklist to complete before any shares are acquired

The tax advantage

Why this structure is exceptionally tax-efficient

A small trading company with turnover below $50 million pays company tax at 25%, generating franking credits on dividends paid to shareholders. When those dividends flow into an SMSF in accumulation phase, taxed at 15%, the franking credit typically exceeds the fund's liability, producing a cash refund. In pension phase, where the SMSF pays 0% tax, the full franking credit is refunded. On a $100 pre-tax profit, a pension-phase SMSF receives $100 in total, the most tax-efficient outcome available in the Australian system.

Advantages and risks

What to weigh before proceeding

Advantages

✅ Franking credits plus 15% / 0% SMSF rates create an exceptional after-tax return

✅ Company assets are separate from the fund and from individual members

✅ Pooled capital accesses business opportunities neither fund could justify alone

✅ Retained earnings compound inside the company at 25% tax

✅ Shares pass via death benefit rules without disrupting operations

Risks & drawbacks

  Private company shares cannot be quickly sold or redeemed

  50/50 deadlock risk without robust shareholders agreement provisions

   Annual independent valuation cost and complexity

✕  SMSF wind-up complications if benefit payments must be made urgently

  Relationship risk as personal circumstances of members change over time
