Australian Invoice Template
Australia's GST system demands precise invoicing from every registered business. If you operate a consultancy in Sydney, a construction firm in Melbourne, or a freelance practice in Brisbane, Eonebill's Australian Invoice Template gives you a document that satisfies every requirement under the A New Tax System (Goods and Services Tax) Act 1999. The template comes preconfigured with the 10% GST rate, ABN fields, AUD currency formatting, and all mandatory information the ATO expects to see on a compliant tax invoice. Download, customise, and send — professional Australian invoicing made simple.
What Makes an Australian Invoice Different
Australia's GST regime sets it apart from other Commonwealth countries. Unlike the UK's VAT system or Canada's HST/GST hybrid, Australia applies a flat 10% GST across all taxable supplies, with no reduced rates for different categories of goods and services. This simplicity in rate structure is accompanied by strict documentation rules: a tax invoice must clearly display the words "Tax Invoice," the supplier's ABN, the date, a description of the goods or services, the GST amount (or a statement that the total includes GST), and the buyer's identity or ABN.
Another distinct feature is the concept of "GST-free" and "input-taxed" supplies. A professional Australian invoice must distinguish between these categories. For example, a graphic designer supplying digital services to an overseas client may declare the supply "GST-free Exports" on the invoice. Businesses that deal in mixed supplies — some taxable, some GST-free — must maintain clear line-item breakdowns that allow the recipient to understand exactly which items attract GST.
The ABN also plays a larger administrative role in Australia than equivalent numbers do in other countries. It is used for all business dealings with the Australian Government, and many businesses will not engage with suppliers who cannot provide an ABN. This makes the ABN field on invoices particularly important for establishing supplier legitimacy.
Key Requirements for Australian Invoices
Legal Mandatory Fields
A valid Australian tax invoice must include: the words "Tax Invoice" in a prominent position, the supplier's Australian Business Number (ABN), the supplier's business name or individual name, the date of the invoice, a brief description of each item supplied, the quantity and unit price of each item, the GST amount for each line item (or confirmation that the total includes GST), the total amount payable, and the recipient's name or ABN. For invoices under AUD $1,000, you do not need to show the buyer's ABN, but above this threshold it becomes mandatory.
Tax Identification Numbers
Australia uses two key business identifiers. The ABN is an 11-digit number assigned to every business entity upon registration with the Australian Business Register. It appears on all official business documents, invoices, and receipts. For GST purposes, the ABN must be accompanied by a statement of GST registration status. Businesses can be registered for GST, not registered, or voluntarily registered. If registered, you must include the GST amount on every taxable supply. Some businesses also have a Tax File Number (TFN) for income tax purposes, but this should never appear on customer-facing invoices.
Currency and Number Formatting
Australian invoices use Australian Dollars (AUD, $). The dollar sign goes before the amount ($1,250.00). Thousands separators use commas, and decimals use full stops — identical to US and UK conventions. The ATO recommends showing two decimal places for all monetary values. When quoting foreign currency amounts, always specify the currency (e.g., USD $5,000.00 at AUD/USD 0.62 = AUD $8,064.52) to avoid ambiguity.
