Integrated Goods and Services Tax (IGST) Refund - Process & Benefits

Updated on November 14, 2025 03:25:13 PM

The term IGST means Integrated Goods and Services Tax, it is levied on all interstate supplies of goods and services or across two or more states/Union Territories in India. It is one of the main components of the Goods and Services Tax (GST) regime in India, along with the Central Goods and Services Tax (CGST) and State Goods and Services Tax (SGST). Under the GST law , the central government collects CGST and SGST or only IGST depending upon whether the transaction is intrastate or interstate, respectively.

What is an IGST Refund ?

India’s GST contains the Integrated Goods and Services Tax (IGST) that is imposed on foreign trades for goods and services. Under GST provisions, exports are zero-rated so exporters can apply for a refund of IGST charged on exports. This means that exporters need to pay tax only on the importation of goods or services purchased and then obtain a refund after the goods have been shipped.

There are two sub-categories of such suppliers:

How to Apply for a Refund?

Under Rule 96 of the CGST rule,2017, an exporter may be eligible for a refund of the tax when they ship goods and services outside of the nation after paying the applicable rate of IGST. the refund process differs for goods and services.

For export of goods : The exporter need not file a refund application because the shipping bills or bill of export is considered one. Among the three required export documents, a shipping bill is an application for customs clearance. It is filed on the Indian customs website, ICEGATE. An application for an IGST refund is deemed to have been submitted with a shipping bill when:

These are the two conditions for the refund application, remember refunds are granted on the basis of two returns- GSTR-3B and GSTR-1.

For export of services : In order to claim a refund for an input tax credit on exports made under LUT or bond without paying IGST, the exporter must submit a refund application in form GST RFD-01, which is the same as the required form. The application follows the same procedure as one for exports made without payment of tax.

Process for IGST Refund

Let's see what happens next once the refund application (which is in the form of a shipping bill) is considered to have been filed,

Step 1: Submitting Export Invoices in GSTR-1

The GST website is called GST Network (GSTN) and transmits invoice details contained in GSTR-1 to Icegate electronically

  • Export invoices submitted in GSTR-1/Table 6A: Ensure that the export invoices are submitted with the correct shipping bill number, date, and port code.
  • GSTR-3B returns have been filed for the period in question: The GSTR-3B returns must be filed on time for the relevant period.
  • The requirement for GSTR-3B: It should be equal to or more than the IGST paid as per GSTR-1.

Step 2: Matching GSTR-1 Data with Shipping Bills

After this, there is a process of matching the details on GSTR-1 with shipping bills using Icegate. If there are any discrepancies, then refund claims may be rejected.

Step 3: Icegate Confirming Exported Goods

If the information corresponds, a confirmation by an electronic message will be sent by Icegate to GSTN that those invoices corresponded to goods exported.

Step 4: Tracking the Refund Application

Icegate then works out this claim via a refund application. The exporter gets an Application Reference Number (ARN) which can assist him/her to track his/her application status.

  • SB001: Invalid shipping details
  • SB002: EGM not filed
  • SB003: Invalid GSTN ID
  • SB004: GSTR3 already filed
  • SB005: Invalid Invoice number
  • SB006: Gateway EGM not filed

Validation of bank account through PFMS (Public Financial Management System)

Challenges in IGST Refund Process

The process of claiming an IGST refund for exports has its highs and lows, at least that is the experience most exporters share. Getting refunds is bound to be an issue that exporters encounter and the following reasons may hinder the achievement of this goal. Let's take a look at a few common roadblocks:

What are Returns GSTR 1, GSTR 3 & GSTR 3B

GSTR - 1

Table 6A of form GSTR 1 has been introduced to help exporters claim GST refunds on goods exported out of India. There is currently no invoice-level data in the GSTR 3B return, which is submitted monthly by all taxpayers. Also, GSTR 1 was not filed, and exporters were finding it hard to claim GST refunds. Therefore, Table 6A of Form GSTR 1 was introduced by the government to speed up the GST process for exporters. The person involved in exporting goods from India to claim a GST refund must file Table 6A of form GSTR 1. Once the details of export invoices are filed on the GST Portal under Table 6A, the details will be matched with the details provided in the shipping bill filed with the customs department and the amount mentioned in the GSTR 3B return. When all the information matches, then the GST refunds on exports will be quickly processed by the government.

What is GSTR 3?

GSTR 3 is a monthly return with summarized details of sales, purchases, and sales during the month, along with the amount of GST liability. This return is automatically produced by using data from GSTR-1 and GSTR-2. the amount of GST liability for a given month will be displayed on GSTR-3. The taxpayer should pay the tax and file the return.

Every registered person is required to file GSTR-3, whether there are any transactions made during the month or not.

GSTR-3, once filed, cannot be revised. Any errors in the return may be corrected in the GSTR-1 and GSTR-2 returns for the following month. Since GSTR-3 is automatically generated and does not allow for editing, direct revision is not possible.

How will GSTR-3 and GSTR-3B be reconciled?

The Central Board of Excise and Customs (CBEC) introduced the GSTR 3B, a simple return form. On filing the GSTR 3, if the actual liabilities are different from those declared in GSTR 3B, the system will update the difference between GSTR 3B and GSTR 3 automatically. If the actual liabilities shown in GSTR-3 exceed the amounts declared and paid in GSTR-3B you will be responsible for paying the additional tax, along with interest. GSTR-3 returns are not considered valid until the full tax liability has been paid, otherwise, they must be filed.

Conclusion

IGST refund for exports is a crucial process for registered exporters who have paid IGST on goods exported out of India. The process involves filing the shipping bill and EGM, ensuring accurate data, and rectifying any errors that may arise. IGST refund claims getting stuck are due to the entry of incorrect information in shipping bills and GST returns. So be extra careful while filing these details so that your refund can be processed smoothly without loss of time, effort, and money.
