Tax Invoice under GST - How to Raise a Tax invoice under GST Regime?

Goods and Services Tax (GST) has removed other indirect taxes from the country. It has made a single unified tax system in the country making the tax system easier than previous. In this article, we will deal with how to raise invoice under GST.

Invoice is a non-negotiable instrument issued by the seller at the time of purchase. It includes a list of items, date of purchase, date of shipment etc. Invoices are an important source for bookkeeping and maintaining books of accounts. It helps to find a number of sales and revenue generated. It is also called a bill of lading or bill of sale. At the time of supply of goods, the supplier needs to issue three copies of tax invoice – Original Copy (the buyer gets the original copy of the invoice), Duplicate Copy (It is issued to the transporter to present when required) and third one is Triplicate Copy (It remains with the supplier for his own record). At the time of supply of services, two copies of the invoice are generated – Original (the person getting service), Duplicate (it remains with the person giving service).

The invoice includes a list of particulars which are kept as a proof with the seller and another copy is given to the buyer. The main parts of invoice include:-
