How to Invoice in Australia
Registered businesses issue tax invoices so customers can claim GST credits on eligible purchases.
This page is for general education only. Tax law, e-invoicing rules, and invoice mandates vary by sector, threshold, and updates from authorities. Confirm requirements with a qualified accountant, lawyer, or government guidance for your situation.
Invoicing in Australia requires GST-registered businesses to issue tax invoices that comply with Australian Taxation Office (ATO) rules. The Goods and Services Tax is a flat 10% applied to most goods and services, and any invoice totaling more than A$82.50 (inclusive of GST) must display the supplier's ABN, the GST amount, and a clear description of the supply. Buyers rely on compliant tax invoices to claim input tax credits on their quarterly or monthly Business Activity Statements.
GST registration is mandatory once a business reaches A$75,000 in annual turnover, or A$150,000 for non-profit organizations. Businesses below these thresholds can register voluntarily to recover GST on purchases. Once registered, you must charge GST on all taxable supplies and lodge BAS returns on time to avoid penalties from the ATO.
Payment terms in Australia are negotiable, but 14-day and 30-day terms are the most common across industries. The ATO actively promotes Peppol-based e-invoicing for B2B transactions, and it is already mandatory for Commonwealth government agencies. While PDF invoices remain legally valid when they include all required content, adoption of e-invoicing is accelerating among large enterprises. Australian businesses must retain all invoice records for at least five years, and electronic storage is fully accepted provided records are legible and complete. Using invoicing software that supports ATO-compliant tax invoice generation helps reduce errors and speeds up GST reconciliation during BAS lodgement.
Invoice checklist: common fields in Australia
What buyers, auditors, and tax authorities often expect to see on a commercial invoice. “Required” reflects typical compliance expectations for registered businesses—not every sole trader scenario.
Seller Name & Address
Usually requiredMust match the business name and address registered with the Australian Business Register. Sole traders should use their registered business name or legal name.
Buyer Name & Address
Usually requiredRequired on all tax invoices where the total exceeds A$1,000 inclusive of GST. For invoices under this threshold, buyer details are recommended but not mandatory.
Invoice Number
Usually requiredA unique sequential number used for audit trail purposes. The ATO expects consistent numbering without gaps to ensure traceability during reviews.
Invoice Date
Usually requiredDetermines the tax period for BAS reporting. The date of supply should also be shown if it differs from the invoice issue date.
ABN
Usually requiredThe 11-digit Australian Business Number must appear on all tax invoices. Without an ABN, buyers may be required to withhold 47% from payments under the no-ABN withholding rules.
Tax Breakdown
Usually requiredShow the GST amount separately or clearly state that the total price includes GST. Each line item should indicate whether it is taxable, GST-free, or input-taxed.
Currency
Usually requiredAUD for domestic invoices. Foreign currency invoices are accepted but require documented conversion rates using an ATO-approved method for BAS reporting.
Payment Terms
Often optionalNegotiable between parties. Common terms are 7, 14, or 30 days net. Including clear payment terms reduces disputes and improves cash flow predictability.
Description of Supply
Usually requiredA clear description of the goods or services supplied is mandatory on all tax invoices. Generic descriptions like 'services rendered' may not satisfy ATO requirements.
