The Complete Guide to GST on Service Exports: How to Claim Refunds

For Indian businesses selling software, consulting, digital marketing, design, accounting, IT support or other professional services to overseas clients, understanding gst on service exports is essential. The good news is that qualifying exports are treated as a zero rated supply, which can help exporters avoid the burden of domestic GST and recover eligible input tax credit (ITC).

Before starting international operations, businesses should also ensure their compliance foundation is in place. Proper GST Registration can make it easier to issue compliant invoices, file returns and handle export-related GST procedures correctly.

At GST Wale, we regularly see businesses lose time and money because of small mistakes in invoices, LUT filing, foreign remittance documentation or refund applications. This guide explains the practical side of gst on service exports and how you can claim the refund correctly.

What Is GST on Service Exports?

Under GST law, an export of services can qualify as a zero-rated supply when the prescribed conditions for export of services are satisfied. In simple terms, the service is supplied from India to an overseas recipient, while the relevant place-of-supply and payment conditions are met.

For a service to generally qualify as an export of service, these key conditions need to be examined:

• The supplier is located in India.
• The recipient is located outside India.
• The place of supply is outside India.
• Payment is received in convertible foreign exchange, subject to applicable rules.
• The supplier and recipient are not merely establishments of the same person, subject to the specific statutory provisions.

This is why gst on service cannot be determined simply by looking at where your customer is located. The nature of the service and place-of-supply rules also matter.

GST on Service Exports: Why Are They Zero Rated?

A common misunderstanding is that “zero rated” means the service is exempt from GST. It does not.

A zero rated supply is specifically given favourable treatment under the IGST framework. Exporters can generally make qualifying exports without payment of IGST under a bond or letter of undertaking, and claim a refund of eligible unutilised ITC. Alternatively, where permitted, the exporter may pay IGST and claim a refund of the IGST paid.

For most service exporters, exporting under LUT is commercially attractive because it avoids blocking working capital in IGST.

GST on Service Exports Through LUT

What Is a Letter of Undertaking?

A letter of undertaking (LUT) is a declaration furnished by an eligible registered taxpayer who wants to export goods or services without payment of IGST.

In practical terms, LUT allows you to issue export invoices without charging IGST, provided the export conditions and applicable requirements are satisfied. The GST Portal provides a facility for furnishing LUT, commonly associated with Form RFD-11.

What Is LUT Filing?

LUT filing should ideally be completed before making exports under LUT. The business should maintain proper records of the LUT acknowledgement and ensure that export invoices and GST returns are consistent with the LUT arrangement.

A useful compliance habit is to complete the LUT process at the beginning of the financial year rather than waiting until the first refund application.

How to Claim Refund of ITC on Service Exports

If you export services under LUT without payment of IGST, the usual refund route is a claim for accumulated eligible ITC.

The GST Portal allows taxpayers to file Form GST RFD-01 for refund of ITC relating to exports of goods or services without payment of tax. Multiple tax periods can also be included in one refund application, subject to the applicable system and legal requirements.

Step 1: Maintain Proper Export Invoices

Your invoice should contain the required particulars and clearly reflect that the supply is meant for export under LUT without payment of IGST.

Make sure the following details are consistent across your records:

• Invoice number and date
• GSTIN of the supplier
• Overseas customer's details
• Description of services
• Currency and taxable value
• LUT reference, wherever applicable
• Payment and banking records

Small mismatches can create unnecessary queries during refund processing.

Step 2: File Your GST Returns Correctly

Before submitting a refund application, ensure the relevant GSTR-1 and GSTR-3B returns have been filed. The GST Portal specifically requires applicable returns to be furnished before filing the refund application.

Export invoices reported in GSTR-1 should also match the details used in the refund application.

Step 3: Keep Foreign Remittance Evidence Ready

For service exports, banking documentation proving receipt of export proceeds is particularly important.

The GST Portal's refund guidance specifically refers to FIRC/BRC documentation for export-of-service refund claims.

Therefore, don't treat bank records as an afterthought. Maintain:

• FIRC or applicable bank realisation evidence
• BRC, where applicable
• Foreign inward remittance details
• Customer payment references
• Corresponding invoice details

The exact documentation requirements can depend on the transaction and prevailing rules.

Step 4: Calculate Eligible ITC

Refund is not automatically equal to the entire balance lying in your electronic credit ledger.

The refund calculation considers factors such as:

Refund Amount = Turnover of zero-rated supply × Net ITC ÷ Adjusted Total Turnover

The applicable formula and definitions are prescribed under the GST refund rules.

For service exporters, maintaining a clean ITC reconciliation is therefore extremely important.

Step 5: File Form GST RFD-01

On the GST Portal, select the appropriate refund category for exports without payment of tax and complete the required details.

You generally need to provide:

• Export turnover
• Adjusted total turnover
• Net eligible ITC
• Invoice-level export details
• Supporting documents
• Relevant declarations

The system performs validations against GST return data, and the refund application is subsequently assigned for processing.

What About IGST Refund?

Some businesses choose the alternative route of exporting services on payment of IGST and subsequently claiming an IGST refund, where legally available.

This route can involve additional working-capital requirements because tax is paid upfront. The IGST Act provides the framework for zero-rated supplies and the available refund mechanisms, subject to the prescribed conditions and safeguards.

For many service businesses, exporting under LUT and claiming an ITC refund is therefore easier from a cash-flow perspective.

Does a Shipping Bill Apply to Service Exports?

This is another area where goods and services are often confused.

A shipping bill is primarily associated with export of goods and customs processing. It is not the normal export document for a pure service transaction.

For service exports, the focus is instead on compliant invoices, GST returns, contractual documentation and evidence of receipt of foreign currency/payment through banking channels. The GST Portal specifically distinguishes service-export refund documentation from goods exports, where shipping bill and EGM details may be relevant.

Common Mistakes in GST on Service Refund Claims

1. Treating Every Foreign Client as an Export

A foreign customer does not automatically make every transaction an export of service. Place-of-supply and other statutory conditions must be checked.

2. Delaying LUT Filing

Businesses sometimes begin invoicing overseas clients without completing their LUT compliance. While certain procedural lapses may be capable of being addressed depending on the facts, it is much better to complete LUT compliance in advance.

3. Mismatch Between GSTR-1 and Refund Data

Invoice values, dates and other particulars should reconcile with the refund statement. The GST Portal validates refund information against return data.

4. Ignoring ITC Reconciliation

An inflated refund claim can lead to queries or rejection. Reconcile purchase invoices, GSTR-2B, books and the electronic credit ledger before filing.

5. Poor Export Processing Documentation

Keep contracts, work orders, invoices, bank statements and communication with overseas customers properly organised. Good documentation makes the export processing trail much easier to establish.

Practical Example

Suppose an Indian software company provides development services worth ₹10 lakh to a US client. The company satisfies the conditions for export of services and has a valid LUT.

Instead of charging IGST on the invoice, it exports under LUT. During the relevant period, it has eligible ITC arising from business expenses such as software subscriptions and professional services.

The company can examine its accumulated eligible ITC and file RFD-01 for the applicable refund, subject to the prescribed formula, documentation and other conditions.

The important point is that the company should not simply claim whatever ITC appears in its ledger. The eligible refund must be calculated according to the applicable GST provisions.

GST on Service Export: Compliance Checklist

Before filing your refund, check:

• LUT has been furnished where required.
• Export invoices are correctly prepared.
• Recipient and place-of-supply conditions have been reviewed.
• GSTR-1 and GSTR-3B are filed.
• Export turnover is reconciled with books.
• Eligible ITC is properly reconciled.
• Foreign payment documentation is available.
• Refund invoices match GST return data.
• RFD-01 details have been reviewed before submission.
• Supporting documents are preserved for future verification.
