GST Invoice Guide: GST Tax Invoice Format, Rules



A registered person must issue a tax invoice if he is supplying taxable goods or services. The tax invoice provisions in GST are central to the time of supply rules, the input tax credit system and the matching mechanism. Meaning if an invoice is captures all the relevant details such as of a business transaction including information about both the parties. It will comprise the product name, description, quantity, details of supplier, purchaser, GST Tax rate charged, discounts, terms of sale etc., then we can call such invoice as a GST invoice.

Though GST includes services as well, but the method of invoicing is different for movement of goods and for supply of services. Invoicing under GST (Supply of goods) requires the supplier of taxable goods must issue the tax invoice before or at the time of (a) Removal of goods for supply to the recipient, where the supply involves movement of goods; (b) Delivery of goods or making available thereof to the recipient, in any other case. Whereas in case of supply of services supplier of taxable services is ordinarily liable to issue the tax invoice within 30 days from the date of supply of service. Thus the period and method of invoicing is different for Goods and for services.

Finer Points to note : Removal of goods in GST law means that goods are dispatched for delivery by the supplier on himself or by any other person acting on his behalf and such goods are collected by the recipient on himself or by any other person acting on his behalf.

The other types of invoices in GST :

  • Bill of Supply : A bill of supply is similar to a GST invoice except that bill of supply does not contain any tax amount as the seller cannot charge GST to the buyer. A bill of supply is issued in cases where tax cannot be charged:
  • Registered person is selling exempted goods/services,
  • Registered person has opted for composition scheme
  • Invoice cum bill of supply : If a registered person is supplying taxable as well as exempted goods/services to an unregistered person, then he can issue a single “invoice-cum-bill of supply” for all such supplies.


  • Multiple invoices in one Aggregate Invoice : If the value of multiple invoices is less than Rs. 200 and the buyer is unregistered, the seller can issue an aggregate or bulk invoice for the multiple invoices on a daily basis.
  • Debit and credit note : When goods supplied are returned or when there is a revision in the invoice value due to goods (or services) not being up to the mark or extra goods being issued a Debit Note or Credit Note is issued by the supplier and receiver of goods and services and this occurs in following two situations : (a) When the amount payable by buyer to seller decreases; or when (b) When the amount payable by buyer to seller increases.


How many copies of GST Invoices should be issued : For supply and movement of goods – 3 copies with original marked for Recipient of goods, and duplicate for transporter, and triplicate for the supplier. And for supply of services GST invoicing has to be made in Duplicate, with original marked for Recipient of services and duplicate for the supplier of services.
