GST for small business: Everything you need to know

GST, short for Goods and Services Tax, is something that customers pay as part of a purchase and businesses charge as part of a sale. Even though GST has been around for over two decades now, we understand for some it can still be a little confusing, especially if you’re just starting out on your small business journey.

To help you better understand what it’s all about (and what your obligations are as a small business), we’ve written up this article covering all the details you need to know. Hopefully, it eliminates your GST woes and helps you feel more confident when it comes to tackling this essential business element.

What is GST and how is GST calculated?

So, what is GST exactly? GST is a tax paid on most goods and services sold or consumed within Australia. (For a list of GST-free sales where GST doesn’t apply, you can visit the ATO website).

The current GST rate is 10%, meaning if you charge $100 for a good or service, your customer will be charged $110. The additional $10 is the GST, which will need to be paid to the Australian Taxation Office (ATO). This $110 sale price would be considered GST inclusive, as the tax has already been calculated and included in the sale price.

Calculating GST

There are a few ways to go about calculating GST for products and services.

Adding GST

If you want to add GST to the existing price, simply multiply the amount by 0.1 (or 10%), which will give you the amount to add on. Alternatively, if you want the total price, multiply the original price by 1.1 (110%).

Subtracting GST

You may need to subtract GST to figure out how much GST is included, or the pre-GST price. To determine how much GST is included in a total price, divide the price by 11. If you want the total price before GST was added, divide by 1.1.

When it comes to calculating GST for your business, the Australian Securities and Investment Commission (ASIC) has a handy GST calculator that you can use to work out the amount of GST you will or should charge customers for a certain sale price.

Registering for GST

If your business has a turnover of $75,000 or more for any 12-month period, not just the financial year, you have a legal obligation to register for GST. It’s important to keep an eye on this threshold because once you surpass it, you have 21 days to register your business for GST.

Registering for GST is a fairly straightforward process that can be conducted online through the Australian Business Register (ABR) or via the Business Portal on the ATO website.

Accounting for GST

As a registered business, you can include GST in the price of sales to your customers and claim credits for the GST included in the price of your business purchases. So while GST is paid at each step in the supply chain, businesses don’t actually bear the economic cost of the tax; instead, the cost of GST is borne by the final consumer who can’t claim GST credits. (If your business’ turnover is more than $75,000, you can register for GST if you’re spending a lot on supplies, to claim the GST credits back.)

Here’s an example of what collecting and paying GST on the sale of goods looks like:

A fabric manufacturer sells fabric to a dressmaker for $110 (including $10 GST). The dressmaker uses the fabric to make a dress, which they sell to a boutique for $220 (including $20 GST). The boutique then sells the dress to a customer for $330 (including $30 GST).

Fabric manufacturer sells fabric for $110, including $10 GST
Net GST to pay
GST on sale: $10
Assume no GST credit: $0
Net GST to pay: $10

Fabric manufacturer pays $10 to the ATO
Dressmaker sells dress for $220, including $20 GST
Net GST to pay
GST on sale: $20
less GST credit: $10
Net GST to pay: $10

Dressmaker pays $10 to the ATO
Boutique sells dress for $330, including $30 GST
Net GST to pay
GST on sale: $30
less GST credit: $20
Net GST to pay: $10

Boutique pays $10 to the ATO
Consumer pays $330  (including $30 GST) to the boutique
GST to pay
$30 total GST is paid to the ATO

When you make a taxable sale of more than $82.50 (including GST), your GST-registered customers must be given a tax invoice to claim a GST credit. If they request one and you don’t provide it at the time, you have 28 days from their request to supply it.

If you’re a business using Tyro, you can easily access tax invoices (that clearly outline the GST amount) through the Tyro Portal. To generate a tax invoice in the Tyro Portal, head to Cost > Invoices, select the month you’re after, and click ‘Download PDF’.

Reporting GST

To report GST, you’ll need to submit your business activity statements (BAS) periodically as per the ATO website. These documents should include all the GST charged on your sales and the credits on your business purchases.


GST is an inevitable part of running a business with a 12-month calendar turnover exceeding $75,000. It’s important that you understand your obligations (and how to meet them) so you don’t land yourself in any hot water.
