The structure you operate under determines how you are taxed, your personal liability exposure, and how income can be distributed. Getting this decision right from the start saves significant cost and complexity later.

• Sole trader: the simplest structure - you operate under your own name with an ABN; all business income is your personal income, taxed at individual marginal rates; full personal liability for business debts; no CGT discount is lost at the entity level as the asset is personally held
• Company: a separate legal entity; pays tax at 25% (base rate for entities with aggregated turnover below $50 million) or 30% on passive income; no CGT discount at the company level on share sales; provides liability protection; useful for retaining profits at a lower rate than top personal marginal rates
• Discretionary trust: flexible income distribution to beneficiaries; preserves the 50% CGT discount for assets held more than 12 months; losses are trapped in the trust and cannot offset beneficiary income; subject to land tax surcharge in most states
• Partnership: two or more people carrying on a business together; income passes through to each partner at their personal marginal rate; unlimited joint and several liability between partners; simple but creates exposure if a partner defaults on obligations
• PSI rules (Personal Services Income): if more than 50% of your business income comes from providing your personal skills, knowledge, or efforts to one or a few clients, PSI rules may prevent income splitting through a company or trust - the income is attributed back to you personally regardless of the structure
• Results test: the primary way to escape PSI rules; requires that you are paid for achieving a specific result, supply your own tools or equipment, and are liable for fixing defective work at your own cost; meeting all three elements means PSI rules do not apply
• Professional advice before structuring: the choice of structure has long-term CGT, super, and liability implications; advice upfront typically costs $1,500–$3,000 but prevents costly restructuring later

Unlike employees, self-employed Australians are responsible for setting aside their own tax and paying it quarterly. Failing to do this is the most common financial crisis in early self-employment.

• GST registration: required if annual business turnover exceeds $75,000; once registered, charge 10% GST on taxable supplies, claim GST credits on business expenses, and lodge a Business Activity Statement (BAS) quarterly or monthly
• BAS lodgment: quarterly BAS is due 28 days after the end of each quarter; penalties apply for late lodgment; a registered tax agent can provide a 4-week extension automatically
• PAYG instalments: once your income tax liability exceeds a threshold (typically after your first year of significant self-employment income), the ATO will require quarterly PAYG instalments - pre-payments of your estimated annual tax liability; setting aside 25–30% of gross income from day one prevents a large year-end bill
• Small business tax offset: sole traders with business income may claim a 16% tax offset on their net small business income - maximum $1,000 per year; automatically calculated in your tax return based on the business income component of your taxable income
• Instant asset write-off: small businesses with aggregated annual turnover below $10 million can immediately deduct eligible assets costing less than $20,000 in 2024–25 (rather than depreciating over the asset's effective life); applies to each individual asset - multiple assets can each qualify
• Home office deductions: if you work from home, the fixed rate method allows 67 cents per hour worked at home covering energy, internet, and stationery; the actual cost method requires apportioning all relevant household costs by floor area or usage - keep a four-week representative diary
• Vehicle deductions: if your vehicle is used for business travel (client visits, site work - not commuting to a fixed place of business), claims can be made using cents per kilometre (88 cents/km up to 5,000 km) or the logbook method for higher usage

Self-employed Australians receive no employer super guarantee - every dollar of super must be actively arranged. This is one of the most important financial discipline differences between employment and self-employment.

• No compulsory employer contributions: unless you employ yourself through a company and pay yourself a salary (attracting SG), self-employed sole traders receive no SG on their business income
• Personal deductible contributions: the primary mechanism for self-employed super; contribute to a complying super fund and lodge a Notice of Intent to Claim a Deduction before lodging your tax return - without the notice, the contribution is treated as non-concessional (no tax deduction)
• Concessional cap: $30,000 per year in 2024–25 for personal deductible contributions (plus any employer SG if operating through a company); contributions are taxed at 15% inside the fund - at 37% marginal rate, each $1,000 into super saves $220 in net tax
• Carry-forward contributions: if your super balance was below $500,000 at 30 June in prior years, you can use unused concessional cap from up to five prior years in a single high-income year - particularly valuable after years of lower self-employment income during business establishment
• Non-concessional contributions: up to $120,000 per year (or $360,000 bring-forward over three years) from after-tax profits - useful for moving larger amounts into super in a profitable year
• Super from business sale proceeds: the CGT small business retirement exemption allows up to $500,000 of capital gains from selling a qualifying small business asset to be contributed to super outside the normal contribution caps - a powerful wealth transfer mechanism for business owners approaching retirement
• Quarterly contribution discipline: self-employed people who make one super contribution per year near 30 June often undercontribute during low-cashflow months and then find they have spent what they intended to contribute; automate a monthly or quarterly super contribution from business income

Employees receive workers compensation coverage and often default group insurance through their super fund. Self-employed Australians must arrange all of these personally - and many fail to do so until after they need it.

• Income protection insurance: the most critical cover for a self-employed person; if you cannot work due to illness or injury, there is no sick leave, no employer to maintain your income, and no workers compensation; own-occupation definition is essential
• APRA banned new agreed value IP policies from 31 March 2020: new policies are indemnity-based - benefit calculated on income at time of claim; document business income carefully each year with tax returns and profit and loss statements as evidence of insurable income
• Benefit period and waiting period: choose a benefit period to age 65 (not two-year) and a waiting period of 30–90 days; longer waiting periods reduce premiums but require you to fund the gap from savings - ensure your emergency fund can cover the waiting period
• Professional indemnity (PI) insurance: required for any self-employed professional providing advice or services that clients rely on; PI covers claims arising from errors, omissions, or breaches of professional duty; without it, a single client claim can exceed your personal financial capacity
• Public liability insurance: covers third-party personal injury or property damage claims arising from your business activities; essential if clients or members of the public attend your place of business or you work on client premises
• Business interruption insurance: covers lost income if your business is forced to close temporarily due to events like fire, flood, or other disasters - relevant for businesses with physical premises
• Workers compensation for employees: if you engage employees (even casually), you must maintain workers compensation insurance for them - the penalties for non-compliance are significant

Irregular income is the defining financial challenge of self-employment. The strategies that work for salaried employees need significant adaptation for those whose income varies month to month.

• Business operating account + personal salary: keep a buffer (at least 3 months of personal expenses) in the business account and pay yourself a consistent personal salary each fortnight - this smooths your personal cash flow regardless of business income fluctuations
• Tax reserve account: on every invoice paid, transfer 25–30% to a dedicated tax savings account; never touch this account for personal expenses; when quarterly BAS and PAYG instalments are due, the money is already waiting
• Emergency fund for self-employed: 6–12 months of personal expenses, not the typical 3 months recommended for employees; business income can pause for extended periods during client loss, illness, or economic downturns
• Invoice promptly: delayed invoicing is one of the primary cash flow problems in small business; invoice on the day of service completion, set clear payment terms (14 or 30 days), and follow up overdue invoices at 7 days past due
• Late payment culture: Australian small businesses collectively hold billions in unpaid invoices; consider a 2% early payment discount for clients who pay within 7 days to improve cash flow without changing price
• Separate business and personal finances completely: open a dedicated business bank account and credit card the day you start; mixing personal and business transactions creates BAS complications, reduces deduction legitimacy, and makes it nearly impossible to understand true business profitability

Self-employment creates financial freedom - but also removes every safety net that employment provides. Building your own safety net through insurance, super, and cash management disciplines is non-negotiable.
