How the calculator works
This calculator will help to work out your pay as you go (PAYG) instalments for the current financial year. You can use it to work out your instalment amount or rate to:
- vary your instalment amount or rate if it doesn't reflect your current financial circumstances
- voluntarily enter PAYG instalments.
Enter your financial details for the year, including your estimated income and expenses, and the calculator provides an instalment amount or rate based on your estimates.
When you estimate your income, don’t include any amounts you’ve received, or tax withheld under the First home saver super (FHSS) scheme.
Calculator for individuals
This calculator will not provide accurate results for:
- non-residents (of Australia) for tax purposes
- individuals under the age of 18
- individuals with a substituted accounting period (that is, a financial year other than 1 July – 30 June)
- special professionals who apply the income averaging rules
- primary producers who apply the income averaging rules
- study or training support loan holders for the 2025–26 income year, as the calculator has not been updated with reduced compulsory repayments changes – see Study and training loans – what's new. Using the calculator may provide estimates higher than your actual tax for the 2025–26 income year. The calculator will be updated from 1 July 2026.
Your actual income tax payable will be determined when you lodge your tax return.
