Under the regime of Goods and Services Tax (GST) in India, issuing invoices within a specific timeframe is an important compliance requirement for businesses. The law of GST specifies deadlines for tax invoice issuance to maintain accurate documentation for both businesses and consumers.

These time limits vary, depending on the type of supply and whether it is for the supply of goods or services.

In this blog, we will discuss the time limit for the issue of invoices under GST for goods and services, while highlighting the definition of a tax invoice, the details required in an invoice, and many more.

What Is a Tax Invoice? 

What Is a Tax Invoice ?

A tax invoice is a primary document that outlines the details of a transaction. It consists of essential details of sold goods, like the applicable taxes, quantity, and taxable value. It serves as proof of the time of supply, which enables input tax credit claims for consumers. In India, a supplier must issue a tax invoice to a consumer on account of the sale of goods.

The GST Law defines a tax invoice as ‘a document issued by an input service distributor (ISD) which will also include any additional supplementary or revised invoice issued by a supplier, regarding a previous supply that was made.'

An original GST invoice must include:

  1. It is an essential document which a supplier of services issues.
  2. Any concept-revised invoice or supplementary invoice which a registered person issues for some previous supplies.

Who Should Raise Invoices? 

Any supplier of taxable goods needs to issue an original GST invoice at the time of the sale of goods. The invoice should consist of the product description, value of the products, quantity, and tax liability.

GST receipt voucher needs to be issued during the receipt of advance payment for goods or services. In case a supplier of services does not deliver in return for the advance payment, it leads to the issuance of a refund voucher.

Details Required in a Tax Invoice

Following are the GST invoice rules which are required:

  1. A supplier's name, GSTIN and address
  2. Unique serial number which consists of only numerals and/or alphabets
  3. Date of invoice issuance
  4. Recipient's name, GSTIN and address
  5. Description of the product and/or service
  6. SAC of services or HSN Code of goods
  7. Unique Quantity Code and quantity of goods

  11. State name and the place of supply for inter-state supplies
  12. The total amount of tax payable
  13. Place of delivery if it is not the same as place of supply
  14. Applicability of reverse charge
  15. Mention of ‘supplementary invoice’ or ‘revised invoice’ along with the original invoice’s invoice number and date
  16. Supplier's applicable signature or digital signature
  17. The invoice number, which needs to be a combination of numbers, alphabets and special characters.

  11. Signature: The digital or physical signature of the supplier is essential to check the authenticity of the transaction.

  1. Normal Case: In case there is movement of goods, the issue of tax invoice must be from the location of the supplier to the buyer’s location, on or before goods removal. In case the taxable supply does not involve the movement of goods, the supplier needs to issue the invoice on or before the time of delivery of goods.
