Goods and Services Tax (GST) plays a vital role in everyday transactions across Australia. Whether you own a business or simply want to understand GST better, knowing how to calculate GST is essential. The article will explain everything to you, such as how to calculate it, common formulas, and practical examples.
What is GST in Australia?
GST is a 10% tax applied to most goods and services sold in Australia. It was introduced in 2000 and is collected by businesses registered for GST through their Australian Business Number (ABN). While most goods and services are taxable, some, such as medical services and education, are exempt. Others, like fresh food, are GST-free.
Who needs to calculate GST?
In Australia, you will calculate the GST if:
- If you operate a business, it must be registered for GST if your annual turnover is more than $75,000.
- You send tax invoices to clients or customers.
- It is required to file a Business Activity Statement (BAS) with the ATO or Australian Taxation Office.
If you are not registered for GST, you can not charge or collect it.
How to calculate GST: Key formulas
Calculating GST is straightforward when you know the correct formulas. Here’s an overview of the most typical situations:
1. Steps to add GST to a price
To include GST (10%) in a price, apply the following formula:
The total price with GST is calculated as the original price multiplied by 1.10
- Example: If an item costs $100, you can calculate the price including GST:
$100 × 1.10 = $110
2. Extracting GST from a price that includes GST
To determine the GST amount when it’s already included in the price, you can use this formula:
GST amount = Total price (including GST) ÷ 11
- For example: If the total price is $110, you can determine the GST portion by dividing $110 by 11.
This approach works because the GST portion represents one-eleventh of the overall price.
3. How to calculate the price excluding GST
If you have a GST-inclusive price and want to find the original price (before GST), use this formula:
To find the price excluding GST, simply divide the total price (including GST) by 1.10.
- Example: To calculate the price before GST when the total cost, including GST, is $110, simply divide $110 by 1.10. This will give you $100.
Step-by-step examples of GST calculations
Here are some real-life examples to make it easier to understand:
Example 1: Adding GST to a product
Suppose you sell a product for $200. To add GST:
- Multiply $200 by 1.10:
$200 × 10% GST = $220 (total price with GST included).
The GST amount is $220 – $200 = $20.
Example 2: Extracting GST from a GST-inclusive price
You purchase a product for $220 (GST included). To determine the original price:
$220 ÷ 1.10 = $200 (GST-exclusive price)
GST amount: $220 – $200 = $20
Example 3: Calculating GST for multiple items
If you purchase multiple items worth $500 (excluding GST) and need to calculate the total cost:
- Add GST: $500 × 1.10 = $550.
The total GST amount is: $550 – $500 = $50.
Tools for calculating GST
If you do not want to calculate GST naturally, many tools available for calculate GST:
- GST calculators: Many free GST calculators available online. Only enter the amount, and the remaining work will be done by calculator.
- Accounting software: Programs like MYOB, Xero, or QuickBooks automatically calculate and report GST for your business.
