LUT stands for Letter of Undertaking. Under GST, it allows eligible registered taxpayers to export goods or services without paying Integrated Goods and Services Tax (IGST) upfront, subject to applicable conditions.

LUT is filed electronically in Form GST RFD-11 on the official GST portal. It is particularly useful for exporters who want to avoid paying IGST first and then applying for a refund. <Cite refs={[“turn180124search0″,”turn180124search2”]}/>

Who Can Use LUT?

Generally, GST-registered taxpayers who make eligible exports or other qualifying zero-rated supplies can furnish an LUT, subject to applicable eligibility requirements and exemptions.

It is commonly used by:

• Businesses exporting goods.
• IT companies providing eligible services to overseas clients.
• Consultants and professionals supplying eligible services internationally.
• Other registered exporters making qualifying zero-rated supplies.

Important: A service provided to a foreign customer does not automatically qualify as an export of services. The applicable GST export conditions must be satisfied. <Cite refs={[“turn180124search1″,”turn180124search13”]}/>

Why Is LUT Important?

The main benefits of LUT include:

• Better cash flow: Avoids paying IGST upfront on eligible supplies.
• Simplified export compliance: Provides a recognised process for exporting without payment of IGST.
• Potential ITC refund: Eligible exporters may claim a refund of unutilised input tax credit, subject to applicable rules.
• Support for international business: Helps eligible businesses manage GST obligations when serving overseas customers. <Cite refs={[“turn180124search2″,”turn180124search4”]}/>
