Filing the GST (Goods and Services Tax) return Forms without any error is a bit difficult and revising it is much trickier. So, to help you out with this, we have come up with this article in which you will get to know ‘How to revise the invoices in the GST?’ we will also learn about supplementary invoices as well as how to use them.

For making taxation simpler, many changes have been made in the GST. It aims to have a free flow of ITC to the taxpayer, along with reporting of all the invoices on a monthly basis which are issued for a transaction. If the taxpayer carelessly does not submit the invoice in the monthly return then it will lead to cut off credit.

Therefore, invoices are a very important part of GST because it contains the date, HSN/SAC Codes, CGST, IGST, SGST amounts, the taxable value of the goods or services, and many more things. And all the mentioned details must be furnished in the monthly returns to know about the credit that has to be availed or the amount of tax that has to be paid.

How to revise a tax invoice under GST?

There are chances that the wrong invoice can be issued or there is also a possibility that already issued invoice might need changes. For such cases, a revision is needed in the invoices. All the revisions must be made as per the monthly returns.

The taxpayer can make the changes in the tax invoices in many ways which include-

• Downward revision in prices of goods or services that are supplied,
• Unward revision in prices of goods or services that are supplied,
• Change in the tax rate of the GST, and many more.

These are the cases by which a taxpayer can furnish the amendments in the issued invoice.

• An upward revision can be done with the help of supplementary invoice.
• The downward revision can be done with the help of a credit note.

It might also happen that the invoice might need a complete revision which means that a “revised” invoice must be issued in this case.

In the GST law, the government has not yet defined the revised invoices separately. Right now, all the registered taxpayer have the provisional GSTN ID Number. After completing the necessary formalities, then the taxpayers will be given a formal registration number in the GST.

The taxpayer having the invoices from the roll-out of GST till they get the formal GST ID number, they must issue a ‘revised’ invoice mandatory. The invoice must be in terms of the GST and must be mandatory issued within 30 days from the date of the receipt of the original registration certificate.

From above, we can clearly conclude that a registered taxpayer cannot issue a revised invoice at any cost after getting the registration certificate. However, one must need a Gen GST billing software for small business to process such transactions with the department.

What are Supplementary invoices and what are its uses?

A supplementary invoice improves the flaws based on the original tax invoice in the GST. It is a possibility that the taxable value of the goods or services might not be mentioned in the original tax invoice due to which lee amount of tax will be charged or other such flaws.

In such cases, the supplier might furnish a supplementary invoice so that such incremental changes can be accommodated which can also include the debit or credit notes. Therefore, any inward or upward revisions can be used in the supplementary invoice.

Along with these changes, the taxpayer must also mention some particulars in the invoice. The GST law does not contain such predefined format but these points must be included in the paper or digital document. Given below are the particulars that must be mentioned mandatory-

• Supplier’s name and address
• Supplier’s GSTIN
• Nature of invoice, i.e. “Debit Note,” “Credit Note,” “Revised Invoice” or “Supplementary Invoice.” must be mentioned in bold.
• The invoice must be written in an alpha-numeric serial number, particularly as per the accounting year
• The invoice date
• Recipient’s name and address
• Recipient’s GSTIN
• If the recipient is an unregistered taxpayer, then he must mention the name and address of the place of delivery as well as the State and code
• The original invoice serial number must be provided for which the supplementary invoice is to be issued
• The differential amount of tax, the taxable value of the goods or services or rate of tax
• Signature of an authorized person for the physical document, or digital signature for the electronic invoice.

Only with this supplementary invoice, the recipient can claim the extra ITC (input tax credit).

Adjusting with the help of the Credit Note

As per the Model GST law, section 2(35) read with section 24(1), a taxpayer can issue the credit note only if a tax invoice has been issued for goods and services supplies and the tax that is charged on the invoice is more than the tax that has to be paid on such supplies. A credit note must have the mentioned particulars.

A credit note can only be issued-

1. If the taxpayer issued a tax invoice for the goods and services they have received.
2. If the tax invoice imposes more amount than the tax that has to be paid.
3. With mentioned particulars.

Therefore, the credit note is like the accounting adjustment which adjusts the real value and tax amounts.
