Exporting services under LUT? How to claim your GST refund

FinEx Editorial Team · 13 November 2026

Exports of goods and services are treated as zero-rated supplies under GST. Exporters generally have two routes:

  1. Export under a Letter of Undertaking (LUT) without paying IGST, and claim a refund of the unutilised input tax credit; or
  2. Export on payment of IGST, and claim a refund of the IGST paid.

Most service exporters choose the LUT route because it avoids blocking cash in tax payments.

Before you export

  • File the LUT on the GST portal for the financial year before making exports under it.
  • Make sure your invoices mention that the supply is meant for export under LUT without payment of IGST.

Documents usually needed for the refund

  • Statement of export invoices for the period
  • Proof of receipt of foreign exchange (for example, bank certificates / FIRC)
  • Computation of eligible ITC as per the prescribed formula
  • Returns for the period filed and reconciled

Time limit

A refund application must be filed within two years from the relevant date. Do not wait until the end — refunds filed promptly are easier to support.

Common reasons for deficiency memos

  • Mismatch between invoice values and foreign exchange received
  • ITC in the claim not matching GSTR-2B
  • Missing or unclear supporting documents
