Why we pay tax: Taxation is the foundation of Australia’s public system. It funds healthcare, education, public transport, national defence, roads, pensions, unemployment benefits and welfare programs. Without a broad-based tax system, individuals would need to pay privately for many of these services, which would heavily disadvantage low- and middle-income households.

Role of the ATO: The Australian Taxation Office (ATO) manages and enforces the tax system. It collects revenue, ensures people and businesses comply with the law, conducts audits and uses data from employers, banks and super funds to cross-check that taxpayers are paying the correct amount.

Why it matters for young Australians: Even in a first job, tax affects every pay packet. Understanding how tax works helps you read payslips properly, plan savings and avoid under-payment errors that can later turn into ATO debts.

Topic example: If a payslip shows \$1,000 gross income with \$150 withheld for tax, then take-home (net) pay is calculated as:

\[ \text{Net Pay} = \$1{,}000 - \$150 = \$850 \]

Main taxes in Australia: The key taxes most Australians come across include income tax on personal earnings from work or investments, GST (a 10% tax included in the price of most goods and services), capital gains tax (CGT) on profits from selling assets such as property or shares, and superannuation tax on contributions and investment earnings inside retirement funds.

How PAYG works: Under Pay As You Go (PAYG), employers withhold tax from wages throughout the year rather than requiring workers to pay one lump sum at tax time. This system smooths out tax obligations and helps prevent unexpected debts to the ATO.

How GST is applied: GST is already built into most prices. For example, a \$110 product includes \$10 GST and \$100 for the underlying good or service. Businesses registered for GST must report and remit the GST they collect, offsetting it against GST they have paid on eligible business purchases.

Personal, company and trust tax rates: Personal income tax uses progressive brackets ranging from 0% to 45%, meaning higher income is taxed at higher marginal rates. Company tax is generally a flat 25–30% depending on business size and classification. Trust income is typically taxed in the hands of beneficiaries at their personal marginal rates.

Topic example: A company earning \$100,000 at a 25% tax rate will pay:

\[ \text{Company Tax} = \$100{,}000 \times 0.25 = \$25{,000} \]

Progressive brackets: Australia uses a progressive tax system, which means that higher income amounts are taxed at higher marginal rates. Only the portion of income that falls inside each bracket is taxed at that bracket’s rate, not your entire salary.

The tax-free threshold: The first \$18,200 of assessable income each year is currently tax-free. This reduces the tax burden for low-income earners and students, and explains why some people pay very little income tax in their first jobs.

Gross vs taxable income: Gross income is your total earnings before deductions. Taxable income is gross income minus allowable deductions and adjustments. The ATO calculates your tax on taxable income, not on the original gross figure.

Why brackets matter: Moving into a higher bracket does not mean all of your income is taxed at that higher rate – only the additional portion above the threshold. Understanding this helps avoid the myth that “earning more can make you worse off.”

Topic example: If you earn \$50,000 and claim \$2,000 in legitimate deductions, your taxable income is:

\[ \text{Taxable Income} = \$50{,}000 - \$2{,}000 = \$48{,}000 \]

Income tax is then calculated on \$48,000, not on the full \$50,000.

Who must lodge: Most individuals earning above the tax-free threshold must lodge a return. Even if your income is below \$18,200, you may still need to lodge if PAYG tax was withheld or if you received certain government payments or benefits.

Key steps in lodging a return: The basic process is to gather income records (payslips, income statements, bank interest), enter eligible deductions such as work-related expenses, review pre-filled ATO data via myGov and then submit either online or through a registered tax agent.

ATO online system and risks of not lodging: The myGov system pre-fills much of your data, but missing items can occur – especially if you worked multiple jobs or had freelance income. Late or missed lodgements can attract fines, interest charges and, in serious cases, compliance action or audits.

Why use an accountant: Accountants help ensure your return is accurate and compliant, check that deductions are legitimate and complete, and are particularly useful if you have multiple jobs, investments or property income.

Topic example: If \$5,000 tax was withheld during the year but, after lodging, your actual tax bill is \$4,500, the ATO will refund the \$500 difference back to you.

What deductions do: Deductions reduce taxable income rather than directly reducing the tax bill. Common deductions include work-specific uniforms, protective clothing, tools, self-education related to your job and certain home office expenses.

What offsets do: Tax offsets (or rebates) reduce the actual tax payable after it is calculated. For example, the low-income tax offset reduces the amount of tax payable for eligible lower-income earners, even though their taxable income remains the same.

Topic example – deduction: If income is \$50,000 and you claim a \$500 deduction, new taxable income is:

\[ \text{New Taxable Income} = \$50{,}000 - \$500 = \$49{,}500 \]

If your marginal tax rate is 32.5%, the tax saving is approximately \$500 × 0.325 = \$162.50.

Topic example – offset: If taxable income is \$20,000 and the calculated tax is \$342, but you are eligible for a \$300 tax offset, the payable tax reduces to:

\[ \text{Tax Payable} = \$342 - \$300 = \$42 \]

What you cannot claim: Everyday clothing, normal commuting to and from work, personal meals and private rent are generally not deductible unless they clearly form part of an approved work-from-home or business arrangement and meet ATO rules.

Employer contributions: Employers must currently pay 11% of ordinary time earnings into your superannuation fund. These compulsory contributions are generally taxed at 15% inside the fund, rather than at your personal marginal rate.

Why it is taxed lower: Super tax is deliberately set below most personal tax rates to encourage long-term retirement saving. Over time, the combination of concessional tax and compounding investment returns can significantly increase retirement balances.

Extra contributions and retirement tax: Salary sacrificing extra amounts into super can reduce taxable income, but concessional contributions (including employer super) are capped at \$27,500 per year. After reaching preservation age, withdrawals may be partly or fully tax-free depending on your age and the type of super fund.

Topic example: If an employer contributes \$5,000 into super, tax of 15% equals:

\[ \text{Super Tax} = \$5{,}000 \times 0.15 = \$750 \]

This leaves \$4,250 invested in the fund for your retirement.

Records to keep: Individuals should keep receipts, invoices, payslips, bank statements and other documentation that supports the income they report and the deductions they claim. Digital scans are acceptable as long as they are clear and legible.

Retention period and audits: Most records must be kept for at least five years after lodging the return. While only a small percentage of taxpayers are audited, the ATO uses sophisticated data-matching to flag unusual patterns, large or inconsistent deductions and undeclared income.

Penalties for false claims: If the ATO finds that claims are incorrect, it can disallow the deduction, require repayment of the extra tax plus interest and, in serious cases, apply penalties or prosecution.

Topic example: If you claim a \$2,000 “home office” deduction without keeping records or meeting the ATO method rules, the claim may be rejected. You would have to repay the tax saved on that \$2,000 plus interest, and possibly face penalties.

Australia vs other countries: Australia sits roughly mid-range among developed nations. It relies more heavily on income tax than some countries that use higher consumption, payroll or wealth taxes, and it currently has no federal inheritance tax.

The “wealthy pay less” debate: Higher-income individuals can sometimes reduce taxable income using structures such as companies, trusts, superannuation and deductions. However, on personal income they still face higher marginal rates than low-income earners and contribute a large share of total income-tax revenue.

Role of accountants and the golden rule: Accountants and licensed advisers provide legitimate tax minimisation strategies and help people stay compliant. The golden rule is to always declare all income and keep proper records. Being honest and organised avoids penalties, speeds up refunds and builds strong financial habits.

Topic example: If the tax-free threshold is \$18,200 and a student earns \$17,500, they pay zero income tax for that year. If they earn \$19,000, only the \$800 above the threshold is taxed – not the entire \$19,000.
