key dates for your tax diary

Any business that is registered for goods and services tax (GST) is required to lodge a business activity statement (BAS). This is used to help employers GST, pay as you go (PAYG) instalments, PAYG withholding tax, and any other applicable taxes. The ATO automatically sends out a BAS when it is time to lodge.

The frequency of Business Activity Statement (BAS) submissions during the year depends on the size of the company. Generally, small businesses and private contractors report via a quarterly BAS. Medium-sized organisations report monthly and large employers report fortnightly via electronic payment. Employers must also submit an annual report to the ATO and provide employees with annual payment summaries.
