There is no single worldwide GST invoice format. This guide uses India’s general Central GST invoice rule as the main checklist, then explains how Singapore, Australia and New Zealand differ. In India, a compliant tax invoice identifies the supplier and recipient, carries a financial-year-unique serial number and date, describes and classifies the supply, shows taxable values and the correct tax components, and records place-of-supply and reverse-charge information where applicable.
Why the country must be identified first
Goods and services tax (GST) invoices are controlled by each jurisdiction’s legislation and tax authority. A field that is essential in India may not be required in Singapore, while the document itself has changed in New Zealand. The checklist below is therefore not a universal template: it is the general Indian Central GST Rules checklist, followed by official examples from three other GST systems.

The Central Board of Indirect Taxes and Customs (CBIC) lists the following particulars for a registered supplier’s tax invoice under the general rule. The official rule and its exceptions are available in CBIC’s “Tax Invoice, Credit and Debit Notes” guidance.
#1 Best Overall
| Invoice element | What to include | Important condition |
|---|---|---|
| Supplier identity | Legal name, address and GSTIN of the supplier | Use the registered supplier details. |
| Serial number | A consecutive invoice number | It must be unique for the financial year. One or more series may be used, with characters permitted by the rules. |
| Issue date | Date the invoice is issued | Apply the timing rule that relates to the type of supply. |
| Recipient identity | Customer name, address and GSTIN or UIN, where registered | Do not substitute a generic customer label when the recipient is registered. |
| Unregistered-recipient details | Name and address, delivery address, state name and state code | These specified details apply when the taxable supply to an unregistered recipient is ₹50,000 or more. |
| Classification | HSN code for goods or Accounting Code for services | Use the code applicable to the supplied goods or service. |
| Description | A description of the goods or services | Make it specific enough to identify what was supplied. |
| Goods quantity | Quantity and unit, or the applicable Unique Quantity Code | This row applies to goods, not a service-only invoice. |
| Values | Total value and taxable value after discount or abatement | Show how discounts or abatements affect the taxable amount. |
| Tax rate and tax amount | Applicable rate and amount for each relevant component | Identify central, state, integrated, union-territory tax and cess components as applicable. |
| Place of supply | Place of supply, including the state name for an inter-State supply | Do not omit the state name on an inter-State transaction. |
| Delivery address | Delivery address when it differs from the place of supply | Show the separate address rather than assuming it is the same. |
| Reverse charge | A statement saying whether tax is payable under reverse charge | Mark the invoice clearly either way, using the format required by your process. |
| Authentication | Supplier’s signature or digital signature, or that of an authorised representative | Complete the required signature step before issuing the document. |
Supplier and invoice identity
The combination of supplier name, registered address, GSTIN, invoice serial number and issue date establishes who issued the document and when. The number must run consecutively and remain unique within the financial year, even if your business operates separate series. Configure numbering controls so that cancelled or voided numbers are handled according to your accounting and GST procedures rather than silently reused.
Customer information and the ₹50,000 condition
For a registered recipient, record the customer’s name, address and GSTIN or UIN. For an unregistered recipient, the rule adds a specific address requirement when the taxable supply is ₹50,000 or more: capture the recipient’s name and address, delivery address, state name and state code. This is a threshold for the specified particulars; it is not permission to omit the supplier’s own details, invoice number, tax calculation or other mandatory fields.
Describe and classify what was supplied
Goods invoices need the relevant HSN code, a clear description, quantity and unit (or Unique Quantity Code). Service invoices use the applicable Accounting Code and a service description. A vague line such as “miscellaneous” can make it difficult to reconcile the tax rate, value and classification, so use line descriptions that match your contracts, orders and delivery records.

Show value, tax and adjustments transparently
State the total value and the taxable value after taking discounts or abatements into account. Then show the applicable rate and tax amount, separating the central, state, integrated, union-territory tax and cess components that apply to the transaction. The invoice should let the recipient trace the calculation from the line item through the taxable base to the total payable.
Place of supply, delivery and reverse charge
Include the place of supply and, for an inter-State supply, the state name. Add a delivery address when it differs from the place of supply. Also state whether the transaction is subject to reverse charge. These fields affect how the transaction is reported and who accounts for the tax, so they should be decided before the invoice is approved.
India: a practical issuance workflow
Use this sequence to reduce omissions. It is an operational checklist, not a substitute for checking the rule that applies to your particular supply.
- Confirm the transaction and supplier status. Identify the supplying registration, the goods or services, the customer’s registration status and whether the transaction is intra-State or inter-State.
- Assign the next valid serial number. Select the correct series and verify that the number is consecutive and unique for the financial year.
- Enter both parties’ details. Add the supplier name, address and GSTIN. Add the registered recipient’s name, address and GSTIN or UIN; if the recipient is unregistered and the taxable supply is at least ₹50,000, capture the additional delivery, state and code details.
- Classify and describe each line. Enter the HSN code for goods or Accounting Code for services, then add descriptions, quantities and units where goods are supplied.
- Calculate the taxable value. Apply discounts or abatements, show the resulting taxable value and state the total value.
- Apply and break out tax. Enter the correct rate and amount for every applicable central, state, integrated, union-territory tax and cess component.
- Complete location and liability fields. Record the place of supply, the state for an inter-State supply, any different delivery address and the reverse-charge indication.
- Authorise and issue. Add the supplier’s or authorised representative’s signature or digital signature, then provide the invoice through your approved channel and retain the business record under the applicable GST record-keeping rules.
Indian exceptions: when the general checklist is not enough
CBIC’s invoice rules contain special provisions for categories including certain financial suppliers, goods transport agencies, passenger transportation, input service distributors and delivery challans. The document required for one of these cases may not contain exactly the same fields or serve the same purpose as an ordinary tax invoice. Confirm the applicable provision before adapting a generic template. The general checklist above also does not establish every requirement for exports, special economic zone supplies or electronic-invoice applicability; those questions require current, transaction-specific verification.
Singapore: tax-invoice contents, timing and electronic transmission
Singapore’s Inland Revenue Authority (IRAS) says a tax invoice is generally required when the customer is GST-registered. It should generally be issued within 30 days from the time of supply. The full requirements are set out in IRAS’s “Invoicing Customers” guidance.
A Singapore tax invoice normally includes the words “Tax Invoice,” the supplier’s name and address, GST registration number, invoice date and identifying number, customer name and address, a description of the goods or services, the GST rate, and totals excluding GST, for GST and including GST. A simplified tax invoice may be used when the total including GST does not exceed S$1,000, provided its required fields are present.
Rank #4
Invoice format is not the only compliance issue. IRAS is introducing phased requirements for GST-registered businesses to transmit invoice data using InvoiceNow-ready solutions. A paper invoice book by itself may therefore be inadequate for a business that falls within an electronic-transmission phase. Check the current phase and your business’s applicability directly with IRAS.
Australia: when a tax invoice is required
In Australia, the government’s “How to invoice” guidance says a GST-registered business must provide a tax invoice for a taxable sale over A$82.50 including GST, or within 28 days when a customer asks for one. The mandatory information includes the words “tax invoice,” the business name, ABN, issue date, a description with quantity and price, and the GST payable (if any).
For sales over A$1,000, the buyer’s identity or ABN is also required. These Australian thresholds and fields are not interchangeable with India’s ₹50,000 rule for specified details about an unregistered recipient. A business selling below the Australian trigger may still need to issue a document in other circumstances, including a customer request, so use the official rule for the transaction rather than relying only on the amount.

New Zealand: the current term is “taxable supply information”
New Zealand changed its GST documentation rules on 1 April 2023. Inland Revenue now uses the broader legal concept “taxable supply information” instead of making a tax invoice the required document. Businesses may continue to label a document “tax invoice,” and the information can be exchanged electronically. Inland Revenue’s summary, marked last updated 27 November 2024, is available at “Taxable supply information for GST.”
When dealing with New Zealand customers or suppliers, design your records around the information required for the taxable supply rather than assuming that an old-style tax-invoice label alone satisfies the law.
Jurisdiction comparison at a glance
| Question | India (general rule) | Singapore | Australia | New Zealand |
|---|---|---|---|---|
| Core document or checklist | Tax invoice with supplier, recipient, supply, value, tax, location, reverse-charge and authentication particulars | Tax invoice with prescribed identity, date, description, rate and GST totals | Tax invoice with business identity, ABN, date, supply details and GST payable | Taxable supply information; a document may still be labelled “tax invoice” |
| Customer detail condition highlighted by the authority | Extra unregistered-recipient name, address, delivery, state and code details at taxable value ₹50,000 or more | Customer name and address on a full tax invoice; simplified form may apply at no more than S$1,000 including GST | Buyer identity or ABN required for sales over A$1,000 | Information is tied to the taxable supply; the old label is not the legal test |
| Issuance trigger or timing | Follow the applicable Indian GST rule for the supply and any special category | Generally within 30 days from the time of supply when the customer is GST-registered | Required for taxable sales over A$82.50 including GST, or within 28 days of a customer request | Current rules focus on providing taxable supply information |
| Simplified or electronic option stated by the authority | Special documents and exceptions exist; applicability must be checked by transaction | Simplified tax invoice up to S$1,000 including GST; phased InvoiceNow transmission | Not stated in the cited guidance | Information may be exchanged electronically |
Common implementation mistakes and how to prevent them
- Using one global template. Put the jurisdiction and tax registration on the template name, and maintain separate versions where fields or timing differ.
- Reusing invoice numbers. Lock the numbering sequence by financial year and series; investigate gaps instead of overwriting them.
- Leaving recipient status unchecked. Make the form require GSTIN or UIN for a registered customer and trigger the additional ₹50,000 unregistered-recipient fields when that condition is met.
- Mixing place of supply with delivery address. Store both fields separately so an address difference is visible.
- Showing one combined tax figure. Break out the applicable tax components and rate so the recipient can verify the calculation.
- Assuming a paper book proves compliance. Paper can help with serialised forms, but it does not decide whether the fields are complete or whether electronic transmission is required.
- Ignoring special categories. Before issuing a delivery challan or an invoice for a financial supplier, goods transport agency, passenger transport or input service distributor, check the specific CBIC provision.
What to verify before publishing or deploying a template
Tax rules change and the correct document depends on facts that a blank form cannot know. Before deployment, verify the current authority guidance for the relevant country, registration status, supply type, place of supply, customer threshold, tax treatment, electronic-invoicing obligation and any special document rule. Have the resulting template reviewed by the person responsible for your GST filings, especially where the transaction is cross-border or falls outside the ordinary sale pattern.
