SUPPLEMENTARY TAX INVOICE AND REVISED INVOICE IN GST

[Dr. Sanjiv Agarwal]

Supplementary Tax Invoice

Supplementary tax invoice has not been defined under Model GST law. Supplementary tax invoice has to be issued by taxable person in case where any deficiency is found in a tax invoice already issued by a taxable person. Dictionary meaning of the term ‘supplementary’ is ‘added to complete or make up a deficiency’. Thus, supplementary tax invoice is to be issued where any deficiency is found in a tax invoice issued already to supplement / remove such deficiency.

Details required to be shown

According to Rule 4 of draft GST Invoice Rules, a supplementary tax invoice and / or credit note or debit note shall contain the following particulars:

1. name, address and GSTIN of the supplier,
2. nature of the document,
3. a consecutive serial number containing only alphabets and/or numerals, unique for a financial year,
4. date of issue of the document,
5. name, address and GSTIN/ Unique ID Number, if registered, of the recipient,
6. name and address of the recipient and the address of delivery, along with the name of State and its code, if such recipient is unregistered,
7. serial number and date of the corresponding tax invoice or, as the case may be, bill of supply,
8. taxable value of goods or services, rate of tax and the amount of the tax credited or, as the case may be, debited to the recipient, and
9. signature or digital signature of the supplier or his authorized representative.

 Input Tax Credit

As per section 16(1) of Model GST law, no registered taxable person shall be entitled to the credit of any input tax in respect of any supply of goods and/or services to him unless he is in possession of tax invoice, debit note, supplementary invoice or such other taxpaying document as may be prescribed, issued by a supplier registered under the CGST/SGST or the IGST Act.

However, a taxable person who has received supplies from a supplier who is paying tax under composition levy scheme or supplying non-taxable goods and/or services cannot take input tax credit on the basis of a bill of supply.

Revised invoice

'Revised invoice' has not been defined under Model GST law. Revised invoice may be issued by taxable person in relation to any invoice already issued by him.

Dictionary meaning of ‘revise’ is to re-examine or re-issue an already published document or record of rights or to revise or amend any entry or particulars in the finally published record of rights.

Issue of revised invoice

As per proviso to section 23 of the model GST law read with Rule 4 of the draft GST Invoice Rules, a registered taxable person may issue a revised invoice against the invoice already issued by him during the period starting from the effective date of    registration till the date of issuance of certificate of registration to him. The revised invoice would enable the recipient to take credit of tax charged in the revised invoice.

The period covered for issuing of revised invoice is the period starting from the effective date of registration till the date of issuance of certificate of registration. Therefore, a registered taxable person cannot issue a revised invoice against the invoice issued by him after the date of issuance of certificate of registration.
