LUT under GST: exporting services without paying IGST

1 min read

Exports are zero-rated under GST. A registered exporter can either pay IGST and claim a refund, or export without paying tax by filing a Letter of Undertaking (LUT) in form RFD-11. Most software and services startups choose the LUT route.

When a supply counts as export of services

Under Section 2(6) of the IGST Act, all of these must be true:

  1. 1.The supplier is located in India.
  2. 2.The recipient is located outside India.
  3. 3.The place of supply is outside India.
  4. 4.Payment is received in convertible foreign exchange (or in Indian rupees where RBI permits).
  5. 5.The supplier and recipient are not merely establishments of the same person.

Filing the LUT

  • File RFD-11 on the GST portal before exporting, for each financial year.
  • Signed by the authorised signatory, with two independent witnesses.
  • Valid for the whole financial year.
  • Invoices must state "Supply meant for export under LUT without payment of IGST".

Frequently asked questions
