Retirement planning education
Trusts and companies can help families organise business income, investments, asset protection and estate planning. They can also make tax, Age Pension and succession planning far more complex. This page explains the basics in simple language.
A trust is a relationship where one party, the trustee, holds and manages assets for beneficiaries. In a family trust, the trustee may choose which eligible beneficiaries receive income or capital, based on the trust deed.
The trust is often used to hold investments, run a family business, protect assets from some business risks, and pass wealth across generations. The trust deed is the rulebook.
A company is a separate legal entity registered with ASIC. It has an ACN and may also have an ABN. It can run a business, employ people, own assets and pay company tax on profits.
A company can also act as trustee of a trust or SMSF. This is called a corporate trustee and is often used for cleaner administration and succession.
| Structure | What it does | Where it may help | Watch-outs |
|---|---|---|---|
| Sole trader with ABN | A person runs a business in their own name. | Simple consulting, side income, very early-stage activity. | Little separation between personal and business risk; income taxed personally. |
| Company with ACN/ABN | A company runs the business and pays company tax on retained profits. | Operating business, limited liability, staff, contracts, retained working capital. | Money taken out must be salary, dividends, loan repayment or properly documented; Division 7A can apply. |
| Family / discretionary trust | Trustee distributes income among eligible beneficiaries under the trust deed. | Family investment portfolio, family business, succession and asset protection planning. | Proposed 2026 budget changes may reduce income-splitting benefits from 1 July 2028; trust losses generally stay trapped. |
| Trust with corporate trustee | A company acts as trustee rather than individuals. | Cleaner control, succession, asset-title administration and liability separation. | Extra ASIC fees, company records and director duties. |
| Bucket company / corporate beneficiary | A company receives trust distributions and pays company tax, often retaining cash. | Business reinvestment, smoothing cashflow, retaining profits at company tax rate. | Division 7A, unpaid present entitlement rules, franking and proposed budget changes must be modelled carefully. |
| SMSF | A private super fund that invests for members’ retirement. | Long-term retirement assets, pension planning, business real property in limited cases. | Cannot be used for personal spending before release conditions; strict super laws apply. |
The goal should be lawful tax efficiency, not artificial tax avoidance. In retirement planning, the main value of structures is often control, risk separation, investment discipline and succession — with tax as one part of the design.
A base-rate company may pay a lower company tax rate on retained active business profits than an individual on a high marginal rate. This can help a business reinvest profits, buy equipment, employ staff or build working capital.
But when money is paid to shareholders as dividends, franking credits and personal tax rates must be considered. A company is usually a tax-deferral and reinvestment tool, not a way to permanently avoid tax.
An ABN identifies an enterprise for tax and business dealings. An ACN identifies a registered company. A sole trader can have an ABN but no ACN. A company has an ACN and usually also an ABN.
Your calculator should not treat “has ABN” as the same thing as “has company structure.”
A discretionary trust can distribute income to beneficiaries according to the deed and tax rules. This may help align taxable income with family circumstances, but the rules are complex and changing.
Budget reporting indicates proposed changes to CGT, negative gearing and discretionary trust taxation from 2027–2028. These should be modelled as scenario toggles labelled “proposed / subject to legislation,” not as settled permanent law until enacted.
A company or trust can help a person build business value before retirement. The retirement plan should model salary, dividends, retained earnings, business sale value and whether proceeds are contributed to super or retained outside super.
A family may keep long-term investment assets away from the operating business. This can reduce some business-creditor risk, although it is not bulletproof and can be affected by personal guarantees, insolvency law and family law.
Trusts can help hold assets for children, grandchildren or vulnerable beneficiaries. For retirement calculators, this matters because a user may want a “legacy target” rather than spending all capital.
A person may have super, SMSF assets, trust assets and company assets at the same time. The calculator should model each bucket separately because tax, liquidity, access rules and Age Pension treatment differ.
Add this as an Advanced Calculator section called “Business, Trusts & Legacy Structures.” Keep it hidden from the Simple Calculator unless the user answers “I own a business or family trust.”
| Field | Purpose | Output impact |
|---|---|---|
| Structure type | Distinguish sole trader, company, trust, trust with corporate trustee, SMSF and hybrids. | Controls tax, access and risk assumptions. |
| ABN / ACN presence | Prevents confusing business registration with company registration. | Improves user education and data accuracy. |
| Business profit before owner salary | Models real household cashflow versus retained business profit. | Better retirement savings and tax projection. |
| Owner salary / dividends / distributions | Shows how money actually reaches the household. | Personal tax, super contributions and spending capacity. |
| Retained earnings | Companies may keep profit for future reinvestment. | Models business value and eventual extraction tax. |
| Trust assets and liabilities | Trust assets may support retirement but may not be personally accessible on demand. | Age Pension, estate and legacy modelling. |
| Bucket company toggle | Captures corporate beneficiary use and possible tax deferral. | Requires Division 7A and proposed reform warnings. |
| Expected business sale age/value | Many business owners fund retirement from a future sale. | Adds sale proceeds, CGT and contribution scenarios. |
| Legacy target | Captures money intended for children, grandchildren or a family trust. | Subtracts capital from spendable retirement pool. |
| Professional advice obtained | Flags whether user is modelling a real structure or exploring education only. | Displays risk warnings and avoids overconfident outputs. |
