Understanding Australian GST
The Goods and Services Tax (GST) is a broad-based tax of 10% on most goods and services sold in Australia. It was introduced on 1 July 2000, replacing many state-based indirect taxes. Businesses with a turnover of $75,000 or more per year must register for GST.
Adding GST
Removing GST
Businesses collect GST on behalf of the ATO and can claim input tax credits for GST paid on business purchases. This is reported via your Business Activity Statement (BAS). Contact ProPartners for help with your BAS lodgements.
