GST on Exports in India 2026: LUT, IGST & Refund Process Guide

Exporting goods or services from India sounds simple… find a buyer, pack the stuff, handle shipping right, but really the GST compliance part can be as important, sometimes more. The good part is exports are treated as zero-rated supplies under GST, so eligible exporters can claim refunds, as long as they follow the rules and conditions

For exporters, getting the hang of LUT, IGST, and how the refund works can save you from those awkward delays and cash flow problems. Here’s a sort of GST guide for Indian exporters in 2026

Is GST Applicable on Exports from India?

Exports of goods and services fall under the zero rated supply idea, under the IGST setup. Practically, exporters usually get two options

1. Export without paying IGST by filing a Letter of Undertaking (LUT) and then claim refund of eligible unutilised Input Tax Credit (ITC)

2. Export after paying IGST, then claim refund of the IGST amount later, if everything matches the required conditions

The intention is to stop domestic GST from turning into a hidden cost inside the exported goods or services

What Is LUT and Why Is It Important?

A Letter of Undertaking (LUT) lets eligible registered exporters export without paying IGST at the time the supply happens. So rather than paying the tax first, and then waiting for refund, the exporter can supply under LUT and later claim refund of eligible accumulated ITC

If you’re doing exports often, this approach can help keep working capital under control, honestly it’s one of the reasons many exporters prefer LUT

Also the export invoice should show the right endorsement, like whether it is being done under LUT without IGST payment, or if IGST is paid

Exporting on Payment of IGST

Some exporters also choose to pay IGST on export and then claim refund later

For exports of goods, the shipping bill is basically treated as the refund application for IGST, but only subject to the prescribed conditions. You’ll still need proper filing like the export manifest or report, plus a valid GST return. Then export invoice details get carried through the GST and Customs systems, so the records need to line up

That’s why accurate documentation matters a lot for a smooth GST export refund process

GST Refund Process for Export Business

The GST refund process for export business changes depending on what route you used

If you export under LUT, you generally claim refund of eligible unutilised ITC through the prescribed refund mechanism. The refund application is filed electronically using FORM GST RFD-01, with supporting information and documents

For exports made after paying IGST, the refund is connected to export details and GST return data. So exporters should make sure invoice details, shipping bill info, GST return filings, and export records match without mismatch

Important GST Compliance Tips for Exporters

Following basic GST rules for exporters can make the refund process much easier:

Keep GST registration and bank details updated.
File GST returns accurately and on time.
Maintain correct export invoices and shipping documents.
Ensure GST invoice details match export documentation.
Keep records of eligible Input Tax Credit.
Check that export manifests and reports are properly filed.
Reconcile GST returns with shipping and export records regularly.
