GST Letter of Undertaking(LUT) Filing Online in India
Filing a Letter of Undertaking (LUT) under GST is mandatory for exporters who wish to export goods or services without paying Integrated Goods and Services Tax (IGST). Understanding the GST LUT filing online process helps businesses streamline their GST compliance and avoid unnecessary tax outflows.
GST Registration is the first step before you can file an LUT online in India.
What is LUT in GST?
A Letter of Undertaking (LUT) is a declaration filed by exporters under GST Form RFD-11, allowing them to export goods or services without paying IGST. Instead of paying tax and later claiming a GST refund, businesses can use an LUT to conduct zero-rated supply transactions seamlessly.
The LUT under GST is valid for one financial year and must be renewed annually. It is a critical compliance requirement for all GST registered exporters in India.
Who is Eligible to File LUT Under GST?
Any GST-registered taxpayer who intends to supply goods or services without payment of IGST can file an LUT. However, the following conditions must be met:
- The taxpayer must be registered under GST LUT registration
- The exporter must not have been prosecuted for tax evasion exceeding ₹2.5 crore
- The business must be engaged in zero-rated exports under GST
- Suppliers making supplies to Special Economic Zones (SEZs) are also eligible
- Businesses involved in deemed exports can apply for GST LUT compliance
If the taxpayer does not meet these conditions, they must furnish a LUT bond GST instead of an LUT.
What are the Documents Required for GST LUT Filing?
Before initiating the GST LUT online filing process, ensure the following documents are ready:
- GST LUT application form (RFD-11)
- GSTIN (GST Identification Number)
- PAN Card of the business
- KYC documents of the authorized signatory
- IEC (Import Export Code) for exporters
- Bank details of the business
