In India, businesses that engage in export activities often hear the term LUT in the context of GST. But what exactly is LUT, and why is it important? Let’s break it down.

1. What is LUT in GST?

LUT stands for Letter of Undertaking. It is a formal document that exporters file with the government to export goods or services without paying Integrated GST (IGST).

  • Essentially, LUT allows duty-free export of goods or services.
  • It is valid for a financial year and must be filed before exporting.
  • Exporters can submit LUT online on the GST portal.

Key point: If an exporter does not furnish an LUT, they are required to pay IGST on exports and then claim a refund later — a process that can delay cash flow.

 

2. Benefits of Using LUT

Using LUT provides multiple advantages for exporters:

A) Cash Flow Advantage
  • Without LUT, exporters must pay IGST upfront and then claim a refund.
  • With LUT, there’s no need to pay IGST, improving liquidity and cash flow.
B) Simplified Compliance
  • Filing LUT is a one-time process for a financial year.
  • It reduces the administrative burden of refund claims, paperwork, and bank procedures..
C) Faster Export Transactions
  • Exports can happen smoothly and without delays, as there is no IGST payment to process.
  • Helps businesses maintain good relationships with overseas buyers by ensuring timely delivery.
D) Cost Efficiency
  • Avoids temporary blocking of capital in tax payment, reducing financial strain on small and medium exporters.

 

3. Why Businesses Use LUT

Businesses, especially exporters, prefer LUT because:

  • It allows direct export of goods or services without tax, which is crucial for competitive pricing internationally.
  • Helps in avoiding procedural delays in export finance.
  • Beneficial for companies with high export turnover as it reduces working capital requirements.
  • It is mandatory for availing duty-free export benefits under GST regulations.

5. Disadvantages or Limitations

While LUT offers significant benefits, there are a few points to consider:

  • Valid for one financial year only — needs renewal every year.
  • Exporters must be GST-compliant — no pending dues or violations.
  • Limited to eligible exporters — domestic sales are still taxable under normal GST.

6. How LUT Impacts Business Growth
