Ask the Expert...
What’s the deal with quarterly tax payments versus the annual tax return?
Your annual tax return summarises your entire financial year’s income and expenses. The ATO uses this info to estimate your PAYG payments for the next year. While your fourth quarterly payment might coincide with your annual tax return, they’re not the same. You need to file both!

Frequently asked questions
Do I have to lodge a BAS if I’m not registered for GST?
Usually, no. If you aren’t registered for GST and haven’t been entered into the PAYG instalment system, you typically won’t need to lodge a BAS. However, once your turnover hits $75k, registration is mandatory.
What is the difference between an annual tax return and a BAS?
Your BAS is about “real-time” reporting of GST and instalments during the year. Your Annual Tax Return is the final reconciliation of every dollar you earned and spent, determining if you owe a little more or are due a refund.
Why did the ATO suddenly start charging me PAYG installments?
This usually happens after you lodge a tax return that shows business income. The ATO assumes you’ll earn similar (or more) this year and wants to help you “pay as you go” so you aren’t hit with a massive debt later.
