FAQs - Australian tax codes

How does GST work in Australia?

GST stands for ‘Goods and Services Tax’ which is a broad-based tax of 10%. Businesses that have $75,000 or more in turnover must register for GST with the Australian Taxation Office (ATO) and collect this tax.

What is a Business Activity Statement (BAS)?

A BAS is a form businesses in Australia need to submit to ATO to report and pay various tax obligations, including GST. Accurate use of tax codes ensures correct reporting on the BAS.

What are common GST tax codes used in Australia?

While specific codes can vary between accounting software as listed above, common GST tax codes include:

• GST: For taxable sales and purchases with GST included.
• GST Free: For sales and purchases exempt from GST.
• Input Taxed: For supplies that don't include GST in the price, and GST credits can't be claimed.
• Export Sales: For goods and services sold overseas, generally GST-free.
• Capital Acquisitions: For purchases of capital items that include GST.

How do I determine the correct tax code to use?

The correct tax code depends on the nature of the transaction. It's essential to understand the GST status of your sales and purchases. If you need guidance to properly fill your BAS it is a good idea to consult with a tax professional or refer to the ATO's guidelines.

What happens if I use the wrong tax code?

Using incorrect tax codes can lead to errors in your BAS, resulting in overpayment or underpayment of taxes.
