What is GST?

GST stands for Goods and Service Tax in Australia. It’s collected by businesses on behalf of the Australian Tax Office (ATO). Business owners should be familiar with GST, including the GST rate, how to calculate GST, how to register for GST, and more.

How much is GST?

GST is 10% added to the goods and/or services you sell in Australia. However, some goods or services are GST-free or GST-exempted in certain situations.

How to calculate GST in Australia

There are a couple of formulas you need to remember when calculating GST.

To calculate a GST-inclusive price, multiply the price of goods and/or services by 1.1. For example, if the net sale price of your good is $100, the GST inclusive price is $110 ($100 * 1.1).

To calculate a GST-exclusive price, divide the price of goods and/or services by 1.1. For example, if the total gross sale price of your service is $220, the GST exclusive price is $200 ($220/1.1).

GST may seem simple to work out, however, mistakes can easily be made - use this GST calculator to be error-free!

What goods and services don’t have GST included?

If the seller is not registered for GST, they won’t add 10% GST on top of their sale prices
Financial services e.g., loans and mortgages, interest, bank fees, currency exchange
Residential rent
Donated goods and services
Duty-free goods
Exported goods (we’ll explain it further down)
Basic food, such as fruits, vegetables, meat, fish and eggs

It's always best to consult with a tax professional or refer to the IRD's detailed guidance if you have specific questions about whether a particular good or service is exempt from GST.

How to register for GST

In Australia, the GST registration threshold is $75,000 per year. If you expect your annual turnover to exceed $75,000 per year, you're required to register for GST. If your business's annual turnover doesn't meet the threshold, becoming GST-registered is voluntary.

There are two ways to register for GST:

Online: you can choose to register for GST online, by following these simple steps on the ATO’s website
Via your accountant or tax agent: for example, Beany can take care of it for you when you start and set up a new business.

If you operate your business as a sole trader, your GST number should be the same as your personal IRD number. If you operate through a partnership or company structure, your partnership or company’s GST number will be the same as your partnership or company’s IRD number.

GST responsibilities

Once you’ve become GST-registered, you need to meet your responsibilities, these include:

Charging GST to customers
File your BAS returns
Pay GST (if applicable) to the ATO
Keep records

Here is a list of items you may be able to claim GST back on if they relate to your business:

Raw materials for manufacturing
Packaging expenses
Shipping costs e.g., courier boxes, envelopes, wrapping paper
Mobile phone expenses
Internet expenses
Office expenses e.g., office supplies, desks, chairs
Accounting fees
Cloud-based software for your business
Advertising and marketing costs
Legal expenses
Business-related subscriptions e.g., business magazines
Travel expenses for conferences or tradeshows

What is BAS?

BAS stands for Business Activity Statement and is a form you need to file either annually, quarterly or monthly, depending on the turnover of your business. If you’re registered for GST, you need to lodge BAS. The ATO uses the information you file in BAS to work out GST obligations and refunds. It also helps to report your other tax liability such as PAYG instalments, PAYG withholding tax, FBT, luxury car tax, wine equalisation tax, and fuel tax credits.

When is BAS due in Australia?

Your BAS return and payment due dates can be due monthly, quarterly, or annually, depending on your business’s annual turnover.

For example, businesses that have a turnover above $20 million are required to file their GST on a monthly basis. If your business has a turnover of less than $20 million, you can opt to file on a quarterly basis. You should always ask your accountant if you’re unsure about your filing frequently. If your business turnover is below $75,000 a year or your business is a non-profit organisation that has less than $150,000 annual turnover, you can choose to file GST annually.

Check out our tax calendar for BAS due dates and mark it as important on your calendar.

GST in the sharing economy

GST rules in the sharing economy can be tricky as it depends on what services you offer. 2 examples are Uber and Airbnb.

Uber: you’re required to become GST-registered even though your annual turnover doesn’t meet the $75,000 threshold. This means you’ll charge GST on everything you earn, claim back GST on your business expenses (e.g., fuel, phone expenses, car maintenance), and file BAS returns to report your GST obligations.
Airbnb: there’s no GST component in residential rent - you don’t need to charge your customers for GST if you’re renting your home or room via Airbnb. However, if you’re renting out a commercial residential property, such as a serviced apartment or a room in a hotel, you may need to charge GST.

GST on imported and exported goods

When it comes to imported goods, GST is typically collected by the Australian Customs. Generally, you’ll need to pay 10% GST on top of the purchase price. However, if your goods are valued below $1,000, you don’t need to pay GST to the Customs. Use the GST calculator above to find out how much you're likely to pay for your imported goods!

For exported goods overseas, these sales are generally zero-rated for GST. This means you don’t charge GST on your sales but still can claim back the GST proportion on related expenses, such as shipping and manufacturing costs.
