What Makes a Valid Australian Tax Invoice?
Under the GST Act, a valid tax invoice must include:
- The words "Tax Invoice" (for GST-registered businesses)
- Your identity (business name) and ABN
- The date of issue
- A description of the goods or services
- The GST amount (if any)
- The total price including GST
- The buyer's identity (for invoices over $1,000)
For invoices under $1,000, requirements are simpler, but it's good practice to include all the above.
GST Calculation: The Quick Reference
If you're GST-registered (turnover over $75,000):
- Adding GST: Price × 1.1 = GST-inclusive price
- Extracting GST: GST-inclusive price ÷ 11 = GST component
- Example: $1,000 + GST = $1,100 (GST = $100)
If you're NOT GST-registered, your invoices should state "No GST applicable" or simply not include GST calculations.
Common Invoicing Mistakes
- Missing ABN: If you don't include your ABN, the buyer must withhold 47% of the payment
- Wrong GST treatment: Some services are GST-free (education, health, financial supplies). Check before charging GST.
- No invoice number: Sequential numbering helps with record-keeping and ATO compliance
- Vague descriptions: "Services rendered" isn't enough. Be specific about what was delivered.
- Missing dates: Both the invoice date and payment due date should be clearly stated
