Where the in-house asset rule actually stops

Your SMSF takes units in a registered managed investment scheme. The units sit behind one specific property. At 7.83% of fund assets, you assume the widely held unit trust exception clears the 5% in-house asset cap.

The Full Federal Court disagrees.

Aussiegolfa Pty Ltd (Trustee) v Commissioner of Taxation [2018] FCAFC 122

The Structure

The Benson Fund held 25% of the units in a Burwood Sub-Fund of the DomaCom Fund. Mr Benson's mother held 50%, his sister's SMSF 25%. Together, 100% of the units in a class attached to one student apartment.

The DomaCom constitution let the responsible entity create classes of units, with assets referable to each class and no cross-indemnity between classes [58]. The PDS stated each sub-fund was a separate trust, and that investors took a beneficial interest in the underlying property [147]-[148].

The Analysis

First, distinct trust. Once the class was created and the property appropriated to it, a separate trust arose at general law [149]-[151]. Mr Benson and his Part 8 associates had fixed entitlements to 100% of its income and capital, so controlled the trust under s 70E(2)(a) of the SIS Act [104]. It was a related trust. The units were in-house assets under s 71(1).

Second, the widely held unit trust exception in s 71(1)(h) read with s 71(1A) could not rescue it. Once the sub-trust is the relevant trust, the 20 entity test fails [157].

On s 62, the Court went the other way [177]-[178]. Leasing the apartment to Mr Benson's daughter at market rent did not breach the sole purpose test. There was no financial or non-incidental benefit, and no evidence the investment policy had been shaped by the lease. Moshinsky J flagged the limit at [178]: rent below market, or an investment policy influenced by related-party use, and a collateral purpose will be inferred.

Practitioner Lesson

The rule tracks substance. An MIS wrapper will not save a fund where the units sit on a class with assets ring-fenced to related holders.

1. Is there a distinct trust at general law over the class assets? Asset segregation plus PDS wording about separate trusts usually means yes.

2. Aggregate Part 8 associates when applying s 71(1A). Family groups collapse to a single entity for the 20 holder and 75% tests.

3. s 71(4) sits in reserve. Even if the asset falls outside s 71(1), the Commissioner can treat it as in-house where the substance is engaged [227]. The ATO confirmed this in its Aussiegolfa Decision Impact Statement.

Market-rent leasing to a related party is not a safe harbour. The ATO's view is that a collateral purpose of leasing to an associate can breach s 62 even at market value.
