Businesses today are increasingly engaging in international trade and therefore understanding the GST implications on exports and imports has become essential. A clear understanding of the applicable provisions can help businesses ensure compliance, optimize working capital, and efficiently manage tax refunds.
In this article, we explain the GST treatment of exports and imports, including the available refund options and important points businesses should keep in mind while dealing with international trade.
Understanding GST on Export Transactions
Under GST, exports of goods and services are treated as zero-rated supplies. This means they are not burdened with GST, which helps Indian businesses remain competitive in global markets. A major advantage for exporters is that they can claim refunds of the GST paid on purchases, input services, and business expenses used for making exports.
Refund Options Available to Exporters
Exporters can claim GST refunds in either of the following ways:
1. Export under LUT/Bond without Payment of IGST
An exporter can furnish a Letter of Undertaking (LUT) and export goods or services without paying IGST. In this case, the exporter can claim a refund of the unutilized Input Tax Credit (ITC) accumulated on purchases and input services used for exports.
This is the most commonly used option as it avoids blockage of working capital.
2. Export with Payment of IGST
An exporter may choose to pay IGST on export invoices at the time of supply.
Upon successful completion of export and fulfilment of prescribed conditions, the exporter may claim a refund of the IGST paid on such exports.
Claiming GST Refund: Goods vs Services
| Export Type | Refund Available | How to Claim |
|---|---|---|
| Export of Goods with Payment of IGST | Refund of IGST paid | No separate refund application required. Refund is processed through the Shipping Bill after matching GST return and customs details. |
| Export of Services with Payment of IGST | Refund of IGST paid | File refund application in Form GST RFD-01 along with supporting documents such as FIRC/BRC. |
| Export of Goods under LUT (Without Payment of IGST) | Refund of unutilized ITC | File Form GST RFD-01 on the GST portal and claim refund of accumulated ITC. |
| Export of Services under LUT (Without Payment of IGST) | Refund of unutilized ITC | File Form GST RFD-01 along with FIRC/BRC and other supporting documents. |
Important Note
For export of goods, accurate matching of shipping bill and GST return details is essential for smooth refund processing. For export of services, proof of receipt of export proceeds through FIRC/BRC is one of the most important requirements for claiming a refund.
GST Treatment of Imports
Unlike exports, imports are taxable under GST.
Import of Goods
When goods are imported into India, GST is collected along with customs duties at the time of customs clearance.
Generally, the importer is required to pay:
Basic Customs Duty (BCD)
Integrated GST (IGST)
Other applicable duties and charges
The IGST paid on import of goods is generally available as Input Tax Credit (ITC), subject to the conditions prescribed under the GST law.
Import of Services
When services are procured from a supplier located outside India and the place of supply is in India, the transaction is generally treated as an import of services under GST. In such cases, GST is payable by the recipient in India under the Reverse Charge Mechanism (RCM).
Under RCM, the recipient is required to discharge the applicable IGST directly to the Government and may avail the tax paid as Input Tax Credit (ITC), subject to eligibility.
Common examples of import of services include cloud computing services, foreign consultancy and professional services, technical support, online advertising, digital marketing services, royalty payments, and management or administrative services received from overseas entities.
Important Note
Under Schedule I of the CGST Act, 2017, Import of services by a taxable person from a related person or from any of its establishments located outside India, for business purposes, is treated as a supply, even if no consideration is charged. Accordingly, such transactions may attract GST under the Reverse Charge Mechanism (RCM).
Key Considerations for Businesses Engaged in International Trade
Businesses involved in exports and imports should keep the following points in mind:
Maintain proper documentation such as invoices, shipping bills, Bills of Entry, LUTs, FIRC/BRC, and customs records.
Ensure timely filing of GST returns to avoid delays in refund processing and ITC availment.
Verify refund eligibility and supporting documents before filing refund applications.
Monitor Input Tax Credit reconciliations to ensure credits are correctly reflected and claimed.
Evaluate Reverse Charge Mechanism (RCM) applicability on services received from overseas suppliers.
Review transactions with foreign group entities carefully, as certain services may be taxable even when no consideration is charged.
Maintain consistency between customs records and GST returns to facilitate smooth processing of export refunds.
Keep track of changes in GST and customs regulations that may impact international transactions.
Conclusion
As businesses expand beyond domestic markets, understanding the GST implications of international transactions becomes increasingly important. While exports benefit from the zero-rated supply framework and refund mechanisms, imports of goods and services may attract GST, with credit generally available subject to eligibility. Proper documentation, timely compliance, and a clear understanding of GST provisions can help businesses optimize tax benefits and avoid potential disputes.
