Businesses are required to file tax returns with the ATO on a regular basis. If you file your own income tax returns, the deadline each year is the 31st of October. However, if you're working with an accountant, this deadline may be extended to the 15th of May the following year.
You're also required to file BAS returns on a regular basis. The BAS filing frequency in Australia is monthly, quarterly, and annually. Our key date calendar helps you keep track of these deadlines.
