Calculate Your Income Tax: Find Out How Much You Owe

Table of Contents

    Paying income tax is a crucial part of financial responsibility in Australia. 

    Whether employed, self-employed, or earning from investments, understanding how much tax you owe can help you manage your finances effectively. 

    This guide will break down the essentials of calculating your income tax while highlighting potential deductions and offsets that reduce your overall tax burden.

    Let’s Get Straight to the Point

    In Australia, income tax depends on your income and any deductions or offsets you’re eligible for. 

    Employers usually deduct tax for employees, while self-employed individuals must manage their tax payments. 

    The 2023-24 tax rates are sliding, with changes coming in 2024-25. Most people also pay a 2% Medicare levy. 

    Taxable income includes earnings from employment, pensions, investments, and more, but some income, like lottery winnings and child support, is non-taxable. 

    Consider claiming deductions (work expenses, donations) or using tax offsets to reduce tax

    If you need help, consult an accountant, use the ATO’s Tax Help program, or explore the National Tax Clinic program.

    How Does Income Tax Work in Australia?

    In Australia, you generally need to pay tax on money earned from various sources, including employment, pensions, government payments, and investments. 

    The amount of tax you pay depends on your total earnings and any deductions or offsets you’re eligible for. 

    If you’re an employee, your employer usually deducts the tax directly from your pay and sends it to the Australian Taxation Office (ATO) on your behalf. 

    However, if you’re self-employed, it’s up to you to set aside and pay the tax yourself.

    At the end of each financial year, most individuals must lodge a tax return with the ATO, which you can do through the ATO’s online services, your myGov account, or with the help of a tax agent or accountant.

    Understanding the Australian Income Tax Rates

    1. 2023-24 Income Tax Rates

    Income in Australia is taxed on a sliding scale. The following table outlines the 2023-24 tax rates for Australian residents aged 18 and over. Note that these rates do not include the 2% Medicare levy.

    Taxable Income Tax on This Income
    $0 – $18,200 Nil
    $18,201 – $45,000 19c for each $1 over $18,200
    $45,001 – $120,000 $5,092 plus 32.5c for each $1 over $45,000
    $120,001 – $180,000 $29,467 plus 37c for each $1 over $120,000
    $180,001 and over $51,667 plus 45c for each $1 over $180,000

    Example: If you earned $60,000 during the 2023-24 tax year, your tax would be calculated as follows:

    • Income between $0 and $18,200: No tax = $0
    • Income between $18,201 and $45,000: 19c for each dollar over $18,200 = $5,092
    • Income between $45,001 and $60,000: 32.5c for each dollar over $45,000 = $4,875

    Total Tax Payable: $5,092 + $4,875 = $9,967 (excluding the Medicare levy)

    $190,001 and over $51,638 plus 45c for each $1 over $190,000

    The ATO’s official website provides detailed information on tax rates for foreign residents, working holidaymakers, and those under 18.

    The Medicare Levy and Surcharge

    1. What Is the Medicare Levy?

    The Medicare levy is an additional charge of 2% of your taxable income. It is part of your annual income tax assessment. If you earn a lower income, you may be eligible for a reduction or exemption from the levy.

    2. Medicare Levy Surcharge

    Suppose you, your spouse, and any dependents do not have adequate private health insurance, and your family income exceeds a certain threshold. 

    In that case, you may have to pay a Medicare levy surcharge between 1.0% and 1.5% of your taxable income. 

    For more details, check the ATO website for specific thresholds and conditions.

    What Counts as Your Taxable Income?

    Taxable income is the income you must pay tax minus any deductions you’re entitled to. It includes money from various sources such as:

    • Employment (including tips and cash payments)
    • Most government payments
    • Investments and capital gains
    • Grants, payments, and foreign sources

    The ATO website provides a comprehensive list of taxable income types.

    Non-Taxable Income

    Some income is exempt from tax, such as:

    • Lottery winnings
    • Certain government grants and payments
    • Child support
    • The tax-free portion of a redundancy payment
    • Government super co-contributions

    How to Reduce the Amount of Tax You Pay

    1. Tax Deductions

    Claiming tax deductions can lower your taxable income. Common deductions include:

    • Work-related expenses
    • Union fees
    • Charitable donations
    • Costs related to managing your tax affairs (e.g., accountant fees)

    For a more detailed list, visit the ATO’s page on deductions you can claim.

    2. Tax Offsets

    Tax offsets (rebates) directly reduce the amount of tax you owe. They are applied after calculating your total tax payable. Some common offsets include:

    • Low-income earner offsets
    • Offsets for seniors and pensioners
    • Caring for an invalid relative
    • Taxable portions of a superannuation income stream

    3. Salary Packaging

    Salary packaging or ‘salary sacrificing’ involves arranging to receive a portion of your income as benefits (like superannuation or car payments) instead of salary. 

    This reduces your taxable income, potentially lowering your tax payable. Note that the items or services you receive through salary packaging cannot be claimed as a deduction.
