What is a BAS and how often do I lodge it?

General advice only · AFSL 222640 · Global Mutual Funds Pty Ltd

The direct answer

A Business Activity Statement (BAS) reports your GST, PAYG withholding from wages and PAYG instalments to the ATO. Most small businesses lodge quarterly; businesses with GST turnover of $20 million or more must lodge monthly, and some voluntarily registered businesses can report GST annually. Late lodgement can attract penalties, so keep your books current.

What it depends on

The full answer depends on your specific circumstances. Here’s what matters.

Turnover

Your GST turnover determines whether you report monthly, quarterly or annually.

Employees

If you pay wages, PAYG withholding is reported through your BAS or activity statement.

Who lodges

You can lodge yourself, or through a registered BAS or tax agent, who may have access to extended due dates.
