What is GST?

GST stands for "Goods and Services Tax". It's an official tax that applies to the sale of almost all goods and services in Australia. The rate of GST is decided by the Australian Government. It is one type of indirect and comprehensive taxation. Also, it is levied on almost all types of products, goods, and services within the boundary of the nation.

Customers indirectly pay GST when they purchase the items. After that, the seller pays the tax amount to the Government. This is the flow of the Australian taxation process.

How much GST is Charged in Australia?

The GST rate in Australia is "10%".

It was implemented on the 1st of July, 2000. It brought a progressive change to the Australian economy and also replaced the wholesale tax system.

Our GST Calculator takes the current rate(10%) automatically during calculation. Therefore, you don't need to enter it manually.

GST for Businesses

GST is applied to all the businesses in Australia whether it is profit organizations, non-profit organizations, or self-employed individuals.

In Australia, it's necessary to register GST for businesses having a gross turnaround of about A$75,000 or more. For non-profit organizations, it's A$150,000 per year or more.

Businesses or enterprises include GST on their product selling price. Also, the Australian government allows you to claim tax credits when you buy any GST included goods or services for your business.

How to calculate GST?

It's very simple to calculate GST manually. There are two possibilities that we need to figure out.

  1. GST Inclusion
  2. GST Exclusion

Now let's take some examples to understand it.

Example 1: GST exclusive price is $2300. Find out GST value.

To add or include GST on $2300, we need to multiply the exclusive amount by "0.1".

GST = $2300 × 0.1 = $230

Net Price = $2300
GST = $230
Gross Price = $2300 + $230 = $2530

Example 2: Find out how much GST included in $4500?

To subtract or exclude GST on $4500, we need to divide the inclusive amount by "11". Also, you can directly get the Net price by dividing the inclusive amount by "1.1".

GST = $4500 / 11 = $409.09

Net Price = $4500 / 1.1 = $4090.91

Gross Price = $4500
GST = $409.09
Net Price = $4500 - $409.09 = $4090.91

Our Calculator follows the same process to calculate the Net amount, GST, and Gross amount. If the amount is big then it is not convenient to calculate it manually. So, in that situation, you can use our tool to sort out any big figures.
