Trust Distributions for AU Family Construction Businesses — Section 100A Risk, Beneficiary Planning, and the EOFY Decisions

Discretionary trust structures are the backbone of most AU family construction, EPC, and trade-business arrangements. Done well, they enable income splitting, asset protection, and structural flexibility across multiple generations. Done badly — particularly post the ATO's 2022 ruling on Section 100A — they create audit risk that can crystallise years after the distribution decision.

This guide is for family-run construction operators using a discretionary trust as the primary trading entity (or as part of a group structure). It covers the structure mechanics, the Section 100A reimbursement-agreement risk, beneficiary planning, and the EOFY decisions that need to happen each year by 30 June.

The discretionary trust as a trading vehicle — pros and cons

Why so many family construction businesses use trusts

• Income flexibility: the trustee can distribute trust income to different beneficiaries in different amounts each year based on tax positions

• 50% CGT discount: trust beneficiaries who hold trust interests for >12 months access the 50% CGT discount on distributed capital gains

• Asset protection: trust assets sit outside personal estate (subject to bankruptcy and family law overrides)

• Succession planning: trust deeds can be amended to add/remove beneficiaries across generations

• Family wealth visibility: consolidated single-entity reporting across family members

Why some operators outgrow the trust structure

• Bank facility complexity: banks are increasingly uncomfortable lending into discretionary trusts at scale (typically above $5M facility)

• M&A friction: selling a business held in a trust is more complex than selling a company

• Capital raising: external equity investors usually require corporate structure

• Section 100A audit risk (the major reason this guide exists)

Section 100A — the ATO's reimbursement-agreement rules

Section 100A of the ITAA 1936 has been on the books since 1979. The ATO largely ignored it for 40 years. In February 2022 they issued TR 2022/4 — a Taxation Ruling that effectively reactivated the section and significantly broadened how it's applied.

The rule in plain English: if a beneficiary is "presently entitled" to trust income but someone OTHER than the beneficiary actually receives the benefit of that income, the ATO can treat the arrangement as a "reimbursement agreement" and tax the trustee at the top marginal rate (47% including Medicare levy).

The audit risk crystallises typically 2-5 years AFTER the distribution. So an aggressive 2024 distribution could surface as an ATO audit in 2026-2028.

What ATO considers a reimbursement-agreement red flag

From TR 2022/4 and subsequent guidance, the ATO's risk-rating framework — operators in the WHITE zone are low-risk, operators in the RED zone face audit.

White zone (safe):

• Adult child receives distribution and personally controls/spends the cash

• Adult beneficiary uses distributed cash to fund their own lifestyle (rent, mortgage, expenses)

• Distribution genuinely reflects the beneficiary's economic interest

Blue zone (low risk):

• Distribution paid into beneficiary's account, beneficiary then voluntarily gifts back to parents/trust

• Documented family-law or financial reasons

Red zone (high risk — Section 100A applies):

• Adult beneficiary doesn't personally receive cash; trustee retains and uses for business / other beneficiary's benefit

• "Unpaid present entitlement" (UPE) sitting on trust balance sheet for years without being paid

• Cash distributed but immediately loaned back to trust at zero interest

• Distribution used to fund expenses of someone OTHER than the named beneficiary

• Beneficiary unaware they received the distribution

The unpaid present entitlement (UPE) problem

The most common Section 100A risk we see in construction-family engagements: UPE balances on the trust balance sheet that have been sitting unpaid for years.

Typical pattern: trust distributes $80k to adult daughter (low marginal rate). Trustee never actually pays the cash — it sits as a "loan from daughter to trust" on the balance sheet. Five years later, the loan is $400k. Daughter has never received any of the cash.

Under the ATO's current view, this arrangement may breach Section 100A — the daughter is "presently entitled" to the distribution on paper but the trustee retained the benefit. ATO can disregard the distribution and tax the trustee at 47%.

The fix: actually pay the distribution within 12 months of the resolution. Cash needs to flow to the beneficiary's personal account. If the beneficiary wants to lend it back, that's a separate Division 7A loan arrangement with proper documentation, minimum repayments, benchmark interest rate, and term-loan structure.

Beneficiary planning for construction families

Each EOFY the trustee makes distribution resolutions before 30 June. The decisions should consider each beneficiary's:

• Marginal tax rate (lower = better for trust distribution)

• Other income (existing salary, investment income)

• Age (under 18 = penalty rate of 47% on most income)

• Genuine economic engagement with the trust

• Cash flow needs in the next 12 months (because the cash must actually be paid)

Typical family construction structure with parents (high income) + 2 adult children (variable income):

Recommended approach:

1. Distribute to adult children first, up to ~$45-50k each (filling their lower tax brackets)

2. Distribute residual to parents at their marginal rate

3. Consider a corporate beneficiary (bucket company) for residual amounts to cap at 25% corporate tax rate

4. Pay all cash to beneficiaries within 6-12 months of resolution

5. Document arms-length any subsequent gifts or loans back

The bucket company strategy

For higher-income years where adult children can't absorb all the distribution capacity, a "bucket company" (corporate beneficiary) can be useful:

• Trust distributes excess income to bucket company

• Bucket company pays 25% corporate tax (small business rate) or 30% (general)

• Bucket company can later pay franked dividends to family members in lower-income years

The bucket company isn't a Section 100A workaround — but it's a legitimate way to defer the personal tax timing.

Key compliance points for bucket companies:

• The distribution must be paid in cash (not UPE)

• Any loan back from the bucket company to the trust must be on Division 7A terms (7 or 25 years, benchmark interest, minimum yearly repayments)

• Don't use the bucket company for personal-asset purchases — strict line

EOFY distribution decisions — the annual cycle

For each EOFY (30 June), the trustee needs to:

1. Estimate trust net income for the year

2. Review beneficiary tax positions for the year ending 30 June

3. Model the optimal distribution mix across beneficiaries

4. Pass a formal trustee resolution documenting the distribution decisions BEFORE 30 June (this is mandatory under the Tax Acts)

5. Plan the cash payments to actually pay the distributions within the next 6-12 months

6. Document the rationale for each beneficiary's distribution amount (supports the Section 100A defence)

This is part of every TechEdge Financial Controller and Head of Finance engagement during the May-June close.

Six common mistakes we fix in first-quarter engagements

1. UPE balances sitting on the balance sheet for years. The biggest Section 100A risk. Pay distributions in cash or formalise as Division 7A loans.

2. Distribution resolution drafted after 30 June. Mandatory deadline missed. Trustee taxed at 47% on the affected income.

3. Distribution to non-resident beneficiary. Withholding tax obligations missed. ATO penalty + interest.

4. Distribution to minor child above $416 threshold. Excess income taxed at penalty rate of 47%. Effectively no benefit (and audit risk).

5. No documentation of why each beneficiary received their distribution amount. Section 100A defence is weaker without contemporaneous documentation.

6. Bucket company used for non-arms-length transactions. Division 7A breach. Deemed dividends at 47%.

When to consider restructuring out of the trust

If your trading business held in a discretionary trust hits any of these thresholds, restructuring to a corporate entity may be worth considering:

• Bank facility above $5M and bank is uncomfortable with trust structure

• External equity raise on the horizon

• Sale process initiated (most buyers prefer corporate target)

• Cross-border expansion

• Significant Section 100A risk crystallising

Restructuring is non-trivial — small-business CGT concessions, rollover relief, stamp duty exposure all need careful planning. Engage a tax specialist 12-18 months before the trigger event.
