Discretionary trust compared with a company
Discretionary trustCompany
Tax on profitDistributed to beneficiaries at their marginal rates, so splitting across the family is the engineFlat 25-30%, whoever owns it
Retaining profitNot effectively. Undistributed income is taxed to the trustee at 47%, so every dollar must find a beneficiary by 30 JuneThe core strength: retain and compound at 25%
CGT discountYes, it flows through to individual beneficiaries, so goodwill and asset sales can be effectively taxed at 23.5% or lessNo. This is the exit-tax trap, with the small business CGT concessions as the partial rescue
LossesTrapped in the trust, plus trust loss tests before you can use them laterTrapped in the company
LiabilityA corporate trustee gives comparable protection. Individual trustees carry personal exposure, so always use a corporate trusteeLimited, with the usual director carve-outs

The distribution engine and its modern limits

The trust's pitch is arithmetic: $200,000 spread as $90,000, $90,000 and $20,000 across a couple and an adult student beats $200,000 in one name by tens of thousands. You can run the splits here.

The limits that discipline it now: distributions to under-18s are taxed at penalty rates above a token amount, so the minor-splitting era is long dead; section 100A targets paper distributions where the money round-trips to someone else, with adult-child distributions the parents keep as the ATO's poster case; and every beneficiary must actually be entitled and eventually benefit. Splitting works where the family genuinely shares the economics. As a fiction, it is a compliance program with your name on it.

The hybrid most accountants actually build

A trading trust streams to the family's lower brackets and preserves the CGT discount for the eventual business sale, while a bucket company beneficiary catches profit beyond the family's efficient brackets at 25-30%, with the cash-movement discipline that structure demands.

Frequently asked questions

Is a trust or company better for a small business?
Trusts win on income spreading and the CGT discount at sale. Companies win on retaining profit. Family businesses with a future sale lean trust, often with a bucket company; reinvestment-heavy businesses lean company.
What tax does a family trust pay?
None itself when income is fully distributed, because beneficiaries pay at their own rates. Undistributed income is taxed to the trustee at 47%.
Can a trust retain profits like a company?
Not efficiently, because retention costs 47%. Retaining is what a corporate beneficiary is for.
Can I distribute trust income to my children?
Adult children at their real rates, where they genuinely benefit. Minors face penalty rates beyond a small amount, and round-tripped distributions are section 100A targets.
Do I need a corporate trustee?
Strongly yes. An individual trustee is personally exposed to trust liabilities, which undoes most of the structure's protection.
