Self-Employed Invoice Template - Australia

While you can legally operate as a sole trader without an ABN, most clients—particularly businesses—require one before payment. An ABN is essential if you earn over $75,000 annually or plan to claim GST registration. Registering for an ABN is free and takes 10 minutes online via the Australian Business Register. Many clients use your ABN to verify your legitimacy, making invoices without one harder to process. Self-employed professionals offering services should register as soon as practicable, regardless of income threshold.

You must register for GST once your turnover reaches $75,000 in a 12-month rolling period. Once registered, you're legally required to include GST on all taxable supplies. GST is currently 10% in Australia. Registration isn't optional at the threshold—it's mandatory by law. Many Australian freelancers register earlier voluntarily to claim back GST on business expenses. Once registered, every invoice must show the GST amount separately and your ABN, which significantly affects your invoicing format and tax obligations.

Australian invoices require your ABN, business name, invoice date, invoice number, description of services or goods, price (including GST if registered), client's ABN when known, and clear payment details. The ATO doesn't mandate a specific format, but these elements help with tax deductibility and audit defence. Invoices without an ABN are harder for clients to claim as deductions, slowing payment. Professional templates include all necessary fields. Handwritten or email invoices are legal if they contain required information, though professional templates appear more credible to clients.

Payment terms are flexible—you can set them yourself (Net 7, Net 30, etc.). Australia's standard is Net 30 for business-to-business invoices, but you can require payment on delivery or upfront. Late payment interest is legally permissible under the Australian Consumer Law but should be disclosed on the invoice. Self-employed professionals can add late fees (typically 10%) if invoiced to businesses, though this varies by state. Always specify terms clearly on every invoice to avoid disputes and payment delays.

Even small jobs require a proper invoice if the client is a business—it's not optional. If invoicing a consumer for casual work, an itemised receipt satisfies requirements if GST isn't applicable. For self-employed work under $75,000 annual turnover without GST registration, a simple invoice with your name, date, description, amount, and payment details works. Clients prefer formal invoices regardless of size; they simplify their accounting. Skipping invoices on small jobs creates tax compliance gaps and prevents you claiming business expenses legally.

An invoice is issued before payment; a receipt is issued after payment is received. Invoices request payment and outline terms. Receipts confirm payment completion. For Australian self-employed work, you typically issue an invoice, and the client sends payment. Once paid, you issue a receipt for their records. Some self-employed professionals issue combined invoice-receipts for immediate payment work like trades. The ATO recognises both documents differently for record-keeping. Self-employed professionals must maintain copies of both issued invoices and received payments for audit trails.

You should invoice in Australian dollars as a default. The ATO expects Australian business records in AUD. If invoicing internationally, you can quote in foreign currencies but should note the AUD equivalent for your records. Some Australian clients working with offshore contacts negotiate invoicing in USD or EUR, but you'll pay currency conversion fees when depositing. Your accounting records must convert everything to AUD for tax purposes. For simplicity and compliance, Australian self-employed professionals should stick with AUD invoices for domestic work and clearly state currency for international clients.

The ATO requires Australian self-employed professionals to keep invoices and financial records for five years. This applies to both issued invoices and supporting documentation. Electronic copies stored securely (cloud or backup) satisfy requirements. Keeping records longer (seven to ten years) provides additional protection for disputes or historical business decisions. Invoices are evidence of income and justify business deductions claimed in tax returns. Poor record-keeping is a common audit trigger. Self-employed professionals should establish a system immediately—spreadsheet, accounting software, or folders—not when the ATO asks.
