Exports are important for a country’s economy and GDP(Gross Domestic Product). This is why the government of India treats exports as zero-rated supplies under the goods and services tax (GST) export rules, meaning the GST on these supplies is zero. Exporters can claim input tax credits (ITC) based on the taxes that they paid on the raw materials/production of the particular export.

Exporters can claim input tax credits (ITC) based on the taxes that they paid on the raw materials/production of the particular export. In this blog, we will understand what Zero-rated GST in India is and the ITC refund process.

What is Zero-Rated Supply?

A zero-rated supply under GST refers to the output (exported goods or services) that is taxed at a 0% rate. However, unlike exempted supplies, the exporters can claim input tax credit (ITC) on the taxes they have paid on raw materials needed to make the zero-rated supply. Here’s what’s considered zero-rated supplies under Section 16 of the IGST Act:

  • Export of services or goods, or both
  • Supply of goods or services to Special Economic Zone (SEZ) units or developers

Zero-rated GST in India on exports ensures that there is no incidence of tax either at the point of production or at the supply point. This is why GST is not paid on goods exported and can even be refunded for GST incurred on input services or raw materials.

If you’re exporting goods abroad or supplying to an SEZ, your supply qualifies as zero-rated. The GST export rules aim to promote exports by ensuring taxes do not inflate export prices. This helps Indian products stay competitive internationally.

Understanding Zero-Rated Export under GST

According to the GST export rules, all goods or services that are sent or supplied to another country outside India are considered exports. These are always treated as inter-state supplies, which means Integrated Goods and Services Tax (IGST) is charged on exports. However, the exporters do not pay the tax on these supplies and can apply for an IGST refund export.

  • Pay IGST and Get a Refund: Export goods and services by paying IGST and then claim a refund of the same tax.
  • Letter of Undertaking (LUT) or bond: Export without paying IGST by filing a letter of undertaking or bond, and then claim a refund on the Input Tax Credit (ITC) on inputs used.

Refund Options for Exporters

Here are some of the main refund options for exporters in India

1. Refund of IGST Paid on Exports

Under this system, exporters pay IGST on their export bills when supplying products. The paid IGST is refundable to the exporter once the goods are exported and shipping bills are filed. The GST portal and customs portal are integrated. Hence, when your export manifests and GST return match, you get a refund directly without even filing a form.

2. Refund of Unutilised ITC (Without Payment of IGST)

Exporters have an additional option not to pay IGST at all. However, for this, you need to file a Letter of Undertaking (LUT) before exporting products in a year. If you file a LUT and then export products, you can claim a refund of the unutilized ITC. This is the most suitable option for businesses that do not want to pay tax in the first place.

Both of these options make exports tax-free during the entire process, which fulfils the main goal of zero-rated GST in India.

Process of Claiming a GST Refund on Exports

Here are the steps you can follow for claiming a GST refund on exports:

For Exports where IGST Has Been Paid

  • Fill in Form GST RFD-01 on the GST Portal. You can add several tax periods to a single application.
  • Enter the turnover of Zero-Rated supplies and Adjusted Total Turnover during the refund period.
  • The system auto-populates “Computation of Refund to be claimed,” which can be adjusted downward. Exclude ITC on Capital Goods, transition ITC, or refunds claimed under Rules 89(4A) & 89(4B).
  • The amount of the eligible refund is automatically calculated in the column of the maximum amount of refund to be claimed.
  • Check refund claimed:
    • Does not surpass balances in the Electronic Credit Ledger per head.
    • Not more than the “Maximum Refund amount in Statement 3A.
    • Not more than aggregate balance (IGST+CGST+SGST) in the ledger.
  • Check documentation and ensure:
    • Relevant periods are filed in forms GSTR-1 and GSTR-3B.
    • Exports occurred for which an ITC refund is claimed.
    • Goods exports have Shipping Bill & EGM details; service exports have FIRC/BRC for foreign exchange.
  • ARN is generated and assigned to the Jurisdictional Refund Officer. You can track the status via the portal.

For Exports on Payment of IGST (Under LUT)

  • Submit a (Letter of Undertaking) in the prescribed form before the financial year starts.
  • Export the goods or services under the bond.
  • File your GSTR-1 and GSTR-3B returns with zero-rated supplies.
  • File Form GST RFD-01 for the refund of unused ITC.
  • After verification, the refund is deposited into your bank account.

In export refund GST procedures, exporters are also eligible to claim a provisional refund of 90% of the claimed amount within 7 days, and the remaining 10% after verification of documents.

Documentation Required for GST Export Refund

Here is a list of documents you need to apply for the Export refund GST:

For Export of Goods:

  • Shipping Bill
  • Copy of return evidencing payment of duty
  • Export invoice
  • Export Manifest or Bill of Lading
  • Filing of GSTR-1 and GSTR-3B

For Export of Services

  • Service invoices
  • Bank Realisation Certificate (BRC) or Foreign Inward Remittance Certificate (FIRC)
  • GSTR filings having the export
  • Statement of invoice details

For Supply to SEZ

  • Invoices and proof of receipt of goods/services signed by the SEZ officer
  • A declaration document from the SEZ unit stating that it has not availed of ITC
  • Details of payments

Exporters are one of the most important elements of foreign trade, and the GST system favours them with zero-rated GST in India. The system keeps goods or services for foreign trade tax-free to promote exports and encourage foreign exchange earnings. Whether you pay IGST and get a refund or submit a letter of undertaking, both procedures ensure that no GST cost is levied on your exported services or goods.

Although exports are zero-rated, the already paid IGST can lead to cash flow issues. If you are struggling to maintain cash flow, apply for a business loan with DMI Finance. You can get up to ₹25 lakh without providing any collateral.
