Complete guide to GST registration, returns, schemes, and practical tips for managing VAT as a small business owner in 2026.
The first question most small business owners ask is whether they need to register for VAT. The answer depends on your annual turnover and the nature of your business.
Current VAT Threshold (2024/25):
You must register for VAT if your turnover exceeds A$75,000 in any 12-month period.
If your annual turnover exceeds the A$75,000 threshold, GST registration is mandatory. You must notify ATO within 30 days of the month in which you exceed the threshold. Failure to register can result in penalties.
You can voluntarily register for VAT even if your turnover is below the threshold. This might be beneficial if you make mostly GST-free supplies, as you'll be able to reclaim VAT on inputs while charging customers at 0%.
Registering for VAT with ATO is straightforward. Here's the process:
Collect your Medicare Levy number, business details, business bank account information, and accounting records showing your turnover.
Visit the ATO website and complete the online GST registration form. You'll need a Government Gateway account.
Double-check your business details, VAT scheme preference, and contact information before submitting.
ATO will issue you a GST registration number (usually within 4 weeks). This can then be used on your invoices.
From your effective date of registration, you must charge VAT on taxable supplies and keep digital records.
ATO offers several VAT schemes designed to simplify accounting and reduce compliance burden for small businesses. Choosing the right scheme can save you money and time.
This is the default scheme for all VAT-registered businesses. You charge VAT on each transaction and reclaim VAT on inputs.
Best for: Businesses with complex transactions and significant input VAT to recover.
Instead of calculating VAT on each transaction, you pay a fixed percentage of your gross turnover to ATO. You don't reclaim input VAT on business expenses.
Best for: Service businesses and retailers with turnover up to A$150,000.
You only pay VAT when you receive payment from customers, rather than when you invoice. This improves cash flow for businesses with slow-paying clients.
Best for: Businesses with credit customers and irregular cash flow.
Instead of submitting quarterly BAS (Business Activity Statement), you submit just one return per year. Monthly or quarterly payments on account may be required.
Best for: Busy business owners who want to minimize accounting tasks.
ATO's Single Touch Payroll (STP) initiative requires most VAT-registered businesses to keep records digitally and submit BAS (Business Activity Statement) using compatible software.
1. Gather Your Data: Compile all invoices issued, invoices received, and expense documentation for the quarter.
2. Use Software: Input your data into STP-compatible accounting software (QuickBooks, FreeAgent, Xero, etc.).
3. Review Figures: Check your VAT due, input VAT reclaimed, and net VAT payable or refund due.
4. Submit Return: Submit your BAS (Business Activity Statement) to ATO electronically via the STP platform before the deadline.
5. Settle Payment: Pay any VAT owed to ATO within the specified timeframe (typically 7 days after filing).
Important Deadline Information:
BAS (Business Activity Statement) are typically due 1 month and 7 days after the end of your VAT period. Missing deadlines can result in penalties of up to 5% of VAT due.
Understanding common VAT pitfalls can help you stay compliant and avoid costly errors:
You cannot claim VAT on personal or private expenses. Only business expenses qualify for VAT recovery.
Confusing net and gross figures can lead to significant calculation errors. Use our calculator to avoid mistakes when working with multiple invoices.
Forgetting to claim back VAT on business expenses costs you money. Keep all invoices and ensure you claim all eligible input VAT.
ATO imposes penalties for late filing and payment. File and pay on time to avoid penalties ranging from 5% to 15% of VAT due.
Charging VAT on GST-free supplies (like food) is an error. Ensure you understand what items are GST-free to avoid this costly mistake.
ATO requires 6 years of records. Disorganized or lost records can trigger audits. Use digital systems to maintain clear audit trails.
Reverse Charge VAT is a special mechanism that changes who is responsible for paying VAT in certain circumstances. It's particularly important if your business buys construction services or services from EU suppliers.
When you receive construction services from a sub-contractor, reverse charge VAT applies. Instead of the contractor charging you VAT, you (the buyer) account for the VAT on your own return.
Example: A builder provides construction services worth A$1,200 (net). Under reverse charge:
Our Reverse VAT Calculator helps you quickly extract the exact VAT amount from construction invoices when reverse charge applies.

No, GST registration is not required if your turnover is below A$75,000. However, you can choose to register voluntarily, which may benefit your business if you supply mostly GST-free items or want to appear more professional.
Most VAT-registered businesses file quarterly (every 3 months). However, you can opt for the Annual GST Reporting, which allows you to file just one return per year, or monthly filing if your business requires more frequent submissions.
The Simplified BAS allows eligible small businesses to pay VAT as a fixed percentage of turnover (typically 9-16.5% depending on sector) rather than calculating VAT on individual transactions. You don't reclaim input VAT, but the scheme often results in lower VAT liability, especially for service businesses.
STP is ATO's initiative requiring VAT-registered businesses to keep records digitally and submit BAS (Business Activity Statement) using compatible software rather than manually entering figures on the ATO website. This improves accuracy and compliance while streamlining the filing process.
You can reclaim VAT on most business expenses, but not all. You cannot claim VAT on private expenses, car purchases (only fuel), or supplies that are VAT-exempt (such as insurance or education). Keep proper invoices showing VAT for all claimable expenses.
