Things to know for IGST Refund against Exports of Goods from India with Error Code

As per CGST Rules, refund of IGST is not possible to an exporter if:

  • They have availed of duty drawback on CGST, SGST or IGST. However, they may claim a refund of IGST if they have availed of drawback on basic customs duty 
  • They obtained Inputs at a concessional rate of 0.1%. In such a case, export cannot be with payment of IGST but must be executed through LUT/bond
  • They imported inputs under the Advance Authorization scheme. Here too, the final product must be exported under LUT/bond and not with payment of IGST. (Advance Authorization is an export incentive that allows duty-free import of inputs required in making products for export) 

Also reference may be taken from the Board Circular No. 16/2019-Customs. The Customs officer at the port of export shall proceed to process the IGST refund as per the instructions. Circular may be refer from the CBIC website (

Export with payment of IGST

Exporters can claim the refund of IGST paid at the time of export. The GST refund process for exports in case of goods begins by taking reference to a primary document known as a shipping bill. The shipping bill and other export-related documents should be filed on the Indian Customs Electronic Commerce Gateway (ICEGATE).  
GSTR-1: GST refund process for exports continues on the GST portal in the form GSTR-1. These details are declared in GSTR-1 under Table ‘6A – Exports Invoices’. The details required in this table are as follows:

  • Invoice date 
  • Port code 
  • Shipping bill no./bill of export no. 
  • Shipping bill date/bill of export date 
  • Total invoice value and taxable value 
  • GST payment (‘With Payment of Tax’ needs to be selected) 
  • Whether the supply is eligible for tax at a differential percentage, as notified by the government
  • The tax amount auto-populated but can be edited

Care must be taken to ensure that all the details declared in this table match with the corresponding details declared in the shipping bill. In the case of export of services, fields at 2, 3, and 4 will be left blank.  In case of deemed exports, the invoice will be uploaded as a normal B2B invoice in Tables 4A, 4B, 4C, 6B, 6C – B2B invoices. When entering invoice details, the checkbox for ‘Deemed exports’, ‘SEZ Supplies without payment’ or ‘Sale from bonded warehouse’ may be selected, as applicable.

GSTR-3B: Further, the GST refund process for exports will involve declaration in GSTR 3B too. The relevant amounts need to be filled up in Table 3.1(b)- ‘Outward taxable supplies (zero-rated)’. The IGST amount entered here should be either equal to or greater than the total IGST filled in Table 6A of the corresponding GSTR-1. 

Form GST RFD-01: GST refund process for exports will need the filing of a form RFD-01 (completely online) in particular cases only.

(1) Export of Goods: In the case of export of goods with payment of tax, there is no separate refund application required as the shipping bill itself will be treated as the refund application. The details entered in Form GSTR-1 will be matched with the details mentioned in the shipping bill as filed with ICEGATE. The ICEGATE will then process the refund and credit the same to the bank account as mentioned by the taxpayer on its portal.
