Mastering GST and BAS: Tips for Australian Business Owners

Written by: Brendan Thorp, CPA | Fact Checked by: Daniel Heness, CPA

Understanding the Goods and Services Tax (GST) and Business Activity Statement (BAS) is crucial when managing a business in Australia. These elements are fundamental to compliance with Australian tax law and ensuring your business operations run smoothly.

This guide provides an up-to-date, comprehensive overview of GST and BAS in Australia, focusing on what you need to know to keep your business on the right track.

Let’s get straight to the point

Understanding GST and BAS is crucial for Australian businesses. GST is a 10% tax on most goods and services, with certain exemptions, like essential foods.

Businesses with a turnover of $75,000 or more must register for GST, which allows them to reclaim GST on expenses. Registration is simple and done through the ATO.

Registered businesses must include GST in their prices, issue tax invoices, and submit a BAS, typically quarterly. BAS reports GST collected on sales and paid on purchases, determining if the business owes more GST or is due a refund.

Accurate records are essential, especially for claiming GST credits and adjusting for bad debts. Timely BAS lodgement is key to avoiding penalties.

What is GST in Australia?

The Goods and Services Tax (GST) is a 10% tax levied on most goods and services sold in Australia. This tax is typically included in the price of products and services, meaning consumers generally don’t see it as an additional charge.

However, it’s essential for businesses to understand how GST impacts pricing, invoicing, and reporting.

When is GST Applied?

GST applies to most transactions in Australia, but there are exceptions. Some goods and services are classified as GST-free, including essential food items, certain medical supplies, and educational courses.

Additionally, financial services and certain exports are exempt from GST.

GST on Imports and Exports

For businesses involved in importing goods, GST is usually payable at the time of importation, and this cost can be reclaimed through your BAS. Conversely, exports from Australia are generally GST-free if the goods leave Australia within 60 days of receiving payment or issuing an invoice.

Who Needs to Register for GST?

You must register for GST if your business has a turnover of $75,000 or more per year ($150,000 for non-profits). Additionally, all taxi and rideshare drivers must register for GST, regardless of their turnover.

If your business turnover is below the threshold, you may still choose to register voluntarily, which can be beneficial in certain circumstances.

Benefits of Registering for GST

Registering for GST allows you to claim back GST on your business expenses, reducing your overall tax liability. While this may involve additional administrative work, the financial benefits often outweigh the extra effort.

How to Register for GST

Registering for GST is straightforward and can be done online through the Australian Business Register (ABR) or the ATO Business Portal. You’ll need an Australian Business Number (ABN) to register.

An Australian Company Number (ACN) is also required if you operate your business as a company.

How to Calculate and Add GST

1. Adding GST to Your Prices

When setting prices, GST-registered businesses must include GST in the final price. The simplest way to do this is to add 10% to the base price of your goods or services.

For instance, if a product costs $100, the final price, including GST, would be $110.

2. Issuing Tax Invoices

A tax invoice for sales of $82.50 (including GST) or more is required. It must clearly state the amount of GST included in the total price and include the words “Tax Invoice”.

This document is essential for your customers needing to claim GST credits.

Understanding BAS: Business Activity Statements

1. What is a BAS?

Businesses must submit a Business Activity Statement (BAS) form to the Australian Taxation Office (ATO) to report their tax obligations, including GST. The frequency of BAS lodgement depends on your business’s turnover, but it is typically required quarterly or monthly.

2. What Information is Required for BAS?

Your BAS will require details of your total sales, GST collected on sales, and GST paid on purchases (input tax credits). This information allows the ATO to calculate whether you owe additional GST or are entitled to a refund.

3. Lodging Your BAS

You can lodge your BAS online via the ATO Business Portal, through your accounting software, or by using a registered tax or BAS agent. It’s important to keep detailed records of all transactions as the ATO may request that your tax invoices and other documentation be reviewed.

GST Refunds and Credits

1. Claiming GST on Business Expenses

If registered for GST, you can claim back the GST you’ve paid on business expenses, such as supplies, equipment, and utilities. This is done through your BAS by claiming input tax credits.

It’s important to keep accurate records and receipts to support your claims.

2. Adjustments for Bad Debts

If you use accrual accounting and have paid GST on an invoice that later becomes a bad debt (i.e., the customer does not pay), you can adjust your BAS to claim the GST on that unpaid amount.

BAS Lodgement Deadlines

1. Quarterly and Monthly Lodgements

The frequency of your BAS lodgement depends on your turnover:

  • Monthly: For businesses with a turnover of $20 million or more. BAS is due within 21 days after the end of each month.
  • Quarterly: For businesses with a turnover of less than $20 million. The due dates are:
  • Q1 (July-September): 28 October
  • Q2 (October-December): 28 February
  • Q3 (January-March): 28 April
  • Q4 (April-June): 28 July

2. Annual GST Reporting

Businesses with an annual turnover of less than $75,000 ($150,000 for non-profits) may choose to report and pay GST annually. However, even if you opt for annual reporting, you must still make quarterly payments.

Conclusion

Understanding and managing GST and BAS is crucial to running a business in Australia. Registering for GST when required, correctly calculating GST on sales and purchases, and ensuring timely and accurate BAS lodgements will help you stay compliant and avoid penalties.

Regularly reviewing your GST and BAS processes can also identify potential savings, such as reclaiming GST credits or adjusting for bad debts. Always keep detailed records and consult with a tax professional if you’re unsure about any GST or BAS reporting aspect.
