What Is a GST Invoice and Who Needs to Issue One?

A GST invoice (frequently referred to as a Tax Invoice in Australia, New Zealand, and India) is a legally binding commercial document issued by a registered supplier to a recipient of goods or services. Unlike a basic commercial receipt or proforma quotation, a GST invoice establishes the exact liability of goods and services tax on a taxable supply and serves as mandatory documentary evidence for the buyer to claim an Input Tax Credit (ITC) against their own tax liabilities.

GST Invoice Rules & Compliance FAQs

Clear answers regarding Australian ABNs, Indian GSTINs, calculation methods, and tax auditing.

Under the Australian Taxation Office (ATO) regulations, a valid tax invoice for taxable sales over $82.50 (including GST) must clearly state: (1) that the document is intended as a 'Tax Invoice', (2) the seller's business identity and Australian Business Number (ABN), (3) the invoice issue date, (4) a brief itemized description of goods or services sold, (5) the quantity and price, and (6) either the exact GST amount payable or an explicit statement that the total price includes GST. For sales of $1,000 or more, the buyer's identity or ABN must also be displayed.
In Australia, you must register for GST within 21 days once your annual gross business turnover reaches or exceeds $75,000 AUD (or $150,000 AUD for non-profit organizations), or if you provide taxi or ride-share services regardless of turnover. In India, businesses selling goods with annual turnover above ₹40 Lakhs (or ₹20 Lakhs for services and special category states) must register under GST and quote their 15-digit GSTIN on every tax invoice.
In a tax-exclusive pricing model, GST is calculated by multiplying the taxable subtotal by the GST rate (e.g., 10% in Australia: $1,000 subtotal × 10% = $100 GST, making the total $1,100). In a tax-inclusive model, you can determine the embedded GST component by dividing the gross total by 11 (e.g., $1,100 ÷ 11 = $100 GST). InvoiceBolt calculates your subtotal, tax rate, and final totals automatically.
Yes. Simply switch the currency to Indian Rupee (INR ₹), set the appropriate GST slab rate (e.g., 5%, 12%, 18%, or 28%), and add your 15-digit GSTIN and HSN/SAC code descriptions directly into the Business Details and Line Item fields. The generated PDF will format these figures cleanly for your accounts and GSTR filing.
Failing to issue a compliant tax invoice when requested by a GST-registered customer prevents them from claiming their legitimate input tax credits (ITCs). Under tax authorities like the ATO and Indian CBIC, repeated non-compliance or failure to issue an invoice within 28 days of request can result in formal administrative penalties and audit scrutiny.
No. InvoiceBolt operates 100% locally in your client-side browser memory. Your ABN, GSTIN, customer details, and invoice amounts are never uploaded to any remote database, ensuring strict data privacy and security.
