Skydo: Hey, have you heard about the export rules in India? If we accept foreign payments in Indian currency instead of foreign currency, we'll be liable for GST!

Tech Exporter A: Really? We don't have to pay any GST if you receive our international payments in Foreign currency! 

Skydo: No, According to Indian government regulations, you are exempted from paying GST if you receive payments in foreign currency. 

You may still have to pay IGST (Integrated Goods and Services Tax) on the value of the service at the time of export. However, if you submit an LUT to the tax authorities, you can also save on IGST.

Tech Exporter A: That sounds interesting! How does the LUT work exactly?

Skydo: Well, the LUT is a declaration that you submit to the authorities stating that you fulfil certain criteria and will fulfil the export obligations. Once they accept the LUT, you can claim a refund of the IGST that you paid.

Let's delve deeper into understanding everything there is to know about LUTs for your technology export business!

Understanding LUT

A Letter of Undertaking (LUT) is a formal declaration submitted by an exporter to the relevant GST authorities. It serves as a bridge wherein the exporter undertakes to fulfil certain obligations and adhere to specific conditions laid down by the GST department. 

This undertaking aims to establish the exporter's commitment to following the necessary rules and regulations related to exports under the GST regime. It grants you the privilege of being exempt from paying Integrated Goods and Services Tax (IGST) on your export services.

Eligibility and Application Process

To be eligible for availing the benefits of a Letter of Undertaking (LUT), an exporter must meet the following criteria:

  • The exporter should be a registered taxpayer under the Goods and Services Tax (GST) regime.
  • You must be engaged in the export of goods or services. The LUT facility is primarily available for exporters to facilitate the export of goods or services without paying IGST.
  • The exporter should have no pending tax liabilities or arrears. It is important to ensure compliance with all tax obligations before applying for an LUT.
  • Business owners must have a satisfactory compliance track record, which includes timely filing of GST returns and adherence to other tax-related requirements.

According to the CGST Rules of 2017, a registered individual can provide a LUT in GST RFD 11 form to export goods or services without paying integrated tax as long as they meet all the eligibility requirements. 

Here's a  step-by-step instructions on how to apply an LUT.

Click ‘Sign and File with DSC’ to utilise the DSE option. Sign the application using the registered digital signature certificate of the selected authorised signatory. A warning message box will appear, then click ‘Proceed’. The system will then generate a unique ARN (Application reference number).

To sign and file with EVC, simply click on 'Sign and File with EVC'. A one-time password (OTP) will then be sent to the authorised signatory's registered mobile phone number and e-mail address. Enter the OTP in the pop-up to complete the application signing process.

After submission, a confirmation message will display. The GST Portal will send an ARN (Application Reference Number) to the registered email and mobile of the taxpayer through email and SMS. You can click on the DOWNLOAD button to download the acknowledgement.


Compliance and Renewal

If you fail to comply with the LUT rules, you may be subject to penalties, depending on the nature of the violation.

For example, if you fail to submit a LUT before exporting services, you may be liable to pay the full amount of IGST that you would have been exempt from paying if you had submitted a LUT. You may also be subject to a penalty of up to 100% of the IGST that you should have paid.

Moreover, A LUT is valid for one financial year. This means that you must renew your LUT every year if you want to continue exporting without paying IGST. Typically, the deadline for renewing your LUT falls on the 31st of March in the same financial year in which it expires. 

If you fail to renew your LUT before the expiry date, you will no longer be able to claim an exemption from paying IGST on your exports. You can renew your LUT hassle-free online via the GST portal by following the aforementioned steps. 

Common Challenges and Solutions 

You may encounter common challenges in the LUT process, such as delays in LUT (Letter of Undertaking) approval. The Customs authorities can take several weeks or even months to approve a LUT application. 

These delays can hinder your business operations and impede timely exports. To avoid last-minute hassles, it is better to apply LUT beforehand.

Rectification and amendment procedures can also present challenges. Mistakes or changes in submitted documents may require rectification or amendment. 

To tackle this, it is important to carefully review all documents before submission and promptly address any errors. Seek guidance from experts or professionals in the field to navigate through the rectification process smoothly.

In a Nutshell

The LUT (Letter of Undertaking) is indeed essential for streamlining international transactions and easing the financial load of upfront tax payments. If you're running a tech service company, effectively utilising LUTs can optimise your processes, enhance competitiveness, and boost profits.
