The Goods and Services Tax (GST) is a broad-based 10% tax on most goods, services, and other items sold or consumed in Australia. If your business is registered for GST, you need to include GST in the price of most goods and services you sell, and you can claim credits for the GST included in the price of goods and services you buy for your business.
When you lodge your BAS, you report the GST you've collected on sales (label 1A) and the GST you've paid on purchases (label 1B). The difference is either paid to the ATO or refunded to you. Most businesses lodge BAS quarterly, though some lodge monthly or annually.
You must register for GST if your annual turnover is $75,000 or more ($150,000 for non-profit organisations). Once registered, you must charge GST on your taxable sales, lodge regular BAS, and keep GST records for at least five years.
GST (Goods and Services Tax) is a 10% tax on most goods, services, and other items sold or consumed in Australia. It was introduced on 1 July 2000. Businesses registered for GST collect it from customers and remit it to the ATO.
To add GST, multiply the GST-exclusive amount by 1.1. For example, $100 + GST = $100 x 1.1 = $110.
To remove GST, divide the GST-inclusive amount by 11 to get the GST component, then subtract it. Or simply divide the GST-inclusive price by 1.1. For example, $110 / 1.1 = $100 ex-GST.
You must register for GST if your business has a GST turnover of $75,000 or more per year ($150,000 for non-profit organisations). You can voluntarily register if your turnover is below this threshold.
Some items are GST-free, meaning no GST is charged. Examples include most basic foods, some education courses, some medical services, and exports. These are different from input-taxed items like financial supplies and residential rent.
