  • PAYG instalments

    Whether you run your own business or earn investment income, planning ahead for your income tax is important to help you keep a healthy cash flow.

    Pay as you go (PAYG) instalments help you do this. By making regular payments (instalments) throughout the year you won't have to pay a large tax bill when you lodge your tax return.

    Your payments are made based on your business and/or investment income (which is also known as instalment income). When you lodge your tax return, all the amounts you've paid during the year will be offset against any tax you owe for the year.

    PAYG instalments are different to PAYG withholding. With PAYG withholding, employers collect tax from the payments they make to employees and contractors and send it to the ATO. This helps those people meet their own income tax liabilities.

    Starting PAYG instalments

    When you start PAYG instalments, you may need to know about:

    Terms we use

    Estimated or notional tax

    We estimate your tax by taking the business and/or investment income reported on your most recently lodged tax return and applying current income tax rates to it. We exclude net capital gains from your income, unless you‘re a super fund or self-managed super fund.

    Instalment amount

    This is based on your most recent tax return and includes an adjustment based on likely changes in the economy.

    Instalment income

    This is the business and/or investment income reported on your last tax return, excluding any statutory income (income that's assessable because of tax law, for example, capital gains). Find out what items are included in instalment income.

    Instalment rate

    This is the percentage figure you use to work out how much you need to pay. It helps to make sure the total instalments you pay are as close as possible to the tax that will be payable on your business and/or investment income once you lodge your tax return for the year.

    Why you have entered PAYG instalments

    We work out whether you need to pay PAYG instalments based on information you reported in your latest tax return.

    The following tables outline reasons why you may have entered PAYG instalments.

    Before your PAYG instalments are due, we'll send an activity statement or instalment notice letting you know when your payment is due and how much to pay.

    How to start paying PAYG instalments voluntarily

    If you're new to business, or you think you're going to make a profit from your business or investment income, it’s a good idea to voluntarily enter into the PAYG instalments system. This will help you budget for next years’ income tax, smooth out your cashflow, and you won’t have to pay a large tax bill when you lodge your tax return.

    You can use the PAYG instalments calculator to work out whether you should enter and how much you'll need to pay.

    Making payments

    When you are reporting and making payments, you may need to know about:

    Calculating your PAYG instalments

    Generally, you can choose from two options to work out how much to pay:

    • Option 1 Instalment amount – the simplest option as you pay the instalment amount that we have calculated for you based on your latest tax return.
    • Option 2 Instalment rate – you work out your instalment amount using      
      • an instalment rate we provide
      • your instalment income.

    Option 2 is best if your instalment income changes regularly, because you will apply the rate to your income in each period.

    If you’re eligible to choose between these options, they will both be shown on your activity statement or instalment notice. You'll need to choose one when you lodge and keep using that option for the rest of the financial year. You can change to the other option on your first activity statement of the next financial year.

    Changing the amount you pay

    • lodge a revised activity statement.
