Small Businesses Guide to GST

Whether you’re just starting out or have been established for a while, decoding your GST obligations can be a daunting task. 

In Australia, most goods and services are subject to the goods and services tax (GST). This 10% tax is included in the price consumers are charged for a product or service. Business owners are then required to pay the GST collected from the sales of their products and services to the Australian Tax Office (ATO) periodically.


To understand your responsibilities, read on for our brief GST guide for small business owners.


Does your business need to pay GST?

Contrary to popular opinion, not every business that sells products or services is required to register for GST. According to the ATO, your business is required to register for GST if you meet any of the following criteria:


• Generate $75,000 or more in revenue annually.

• Operate a non-profit organisation which generates $150,000 or more in revenue annually.

• Provide taxi, limousine or ride-sharing travel services.


If you meet one of these criteria, then your business is required to register for GST and you should be charging your customers GST on the sale of your products and services. However, you might be exempt from charging GST if your product or services falls within a special category.


Does GST apply to your products and services?

As a general rule, GST applies to most products and services sold in Australia. However, there are some exemptions to this tax for classes of items deemed essential. The ATO has a comprehensive list of the products and services which are exempt from GST, but here are some types on that list: 


• Basic food products.

• Education courses and materials.

• Medical, health and care services.

• Menstrual products.

• Medicines, medical aids and appliances.

• Water, sewerage and drainage.

• Precious metals.

• Exports and products sold in duty-free shops.


Registering for and paying GST.

Registering and paying GST is very straightforward. If your business meets the above conditions, you’ll need to register for GST with the ATO or risk facing penalties. With your Australian Business Number (ABN), you can register via Online Services, by phone, through your accountant or tax agent, or by completing a form. You’ll be notified in writing to confirm your registration.

Small businesses typically pay GST quarterly through business activity statements (BAS). When you’re registered for GST with an ABN, the ATO will automatically send a BAS to the business myGov account when it’s time to lodge. You can lodge this online or through your accountant or tax agent. You can pay via BPAY, credit card, debit card or payment reference number (online only). Even if you can’t pay the amount due, you should still lodge your BAS on time.


What are GST credits?

When you purchase supplies for your business, the amount of GST you paid is refundable in the form of a credit. This is because GST is a tax for consumers, not businesses or enterprises.


When you go to pay the ATO for the GST you’ve collected through your sales, you can subtract the GST you paid in supplies. So essentially, you’re credited (or refunded if purchases exceed debits on sales) for the GST paid on those items.


What do invoices need to include?

If you’re claiming a GST credit on a purchase greater than $82.50, you’re required to have a tax invoice as evidence. It should include the following information:


• The supplier’s trading name and ABN.

• The invoice date.

• The words “Tax Invoice”.

• A description of the items (i.e., the quantity and price you paid).

• The GST included in the purchase.

• Your ABN (if the item is worth $1,000 or more, including GST).

What is a Bridging Loan? And When Would You Need One?

May 12, 2025
Buying and selling property rarely lines up perfectly. The logistics of it all can be incredibly stressful. If you’ve found the perfect next home but haven’t sold your current one yet, a bridging loan can make your move easier, without having to wait on your current property sale.  What is a bridging loan? A bridging loan is a short-term loan that gives you the funds to buy a new property before your current property has sold. It’s designed to bridge the gap between buying and selling. These loans are generally interest-only and are typically offered for up to 12 months, giving you time to sell and settle on your current home while already owning the next one. When would I need a bridging loan? You might consider bridging finance if: You’ve found your next home but haven’t yet sold your current one. You want to avoid renting or moving twice between sales. You want more time to prepare your home for market to get the best sale price. You're building a new home while still living in your existing one. How does it work? Peak Debt: The lender combines your current mortgage, the cost of the new property (including stamp duty and legal fees), and any interest (if it’s being capitalised). This total is known as your Peak Debt. Interest Only: During the bridging period, you’ll typically pay interest only — or the interest may be capitalised (meaning it’s added to your loan rather than paid upfront). Sell Your Property: Once you sell your existing home, the sale proceeds are used to reduce your Peak Debt. End Debt: The remaining balance becomes your End Debt, which then continues as a standard mortgage. An example of a bridging loan. Your current home loan = $200,000 New home = $800,000 Total bridging loan (Peak Debt) = $1,000,000 After selling your home for $600,000, that amount is used to pay down your loan Remaining loan (End Debt) = $400,000 Things to consider. Like any major financial decision, it’s important to understand all the moving parts before you commit. Time pressure: You typically have 6–12 months to sell. If you don’t sell in time, the lender may step in to sell the property and/or charge default interest. This is an extra interest rate that a lender charges when you fail to meet your loan obligations — in this case, not selling your property within the agreed timeframe. Interest costs: If interest is capitalised, it means you're not making repayments during the loan period, so the interest gets added to the loan balance instead of being paid separately. This means your loan grows each month. Making even small repayments can help keep this under control. Equity & serviceability: Lenders will assess how much equity you have and whether you can manage the loan during the bridging period. Loan-to-value ratio: If your End Debt ends up being more than 80% of the new property’s value, you may have to pay Lenders Mortgage Insurance (LMI). Existing loan setup: If your current lender doesn’t offer bridging loans, refinancing may be required — sometimes triggering break fees if your existing loan is fixed. This means you may have to pay a penalty if you end a fixed-rate home loan early (before the agreed term is up). Is a bridging loan right for you? That’s the big question. Bridging finance can offer flexibility and peace of mind, helping you move forward with confidence rather than being held back by uncertain sale timing. But it’s not without risk or cost — so it’s vital to understand the structure, timeframe, and repayment expectations. If you’re considering your next property move and want tailored advice on whether bridging finance suits your situation, talk to the team at Ascent Property Co. or Ascent Accountants. We can also put you in touch with finance brokers to discuss what is best for you.

The true cost of work perks.

That work perk might be costing you more than you think… Fringe Benefits Tax (FBT) is charged at a whopping 47% — the same as the top personal tax rate. That means lower salary or fewer benefits. So, while salary packaging can save tax, in many cases it ends up costing you more.
