GST Letter of Undertaking (LUT)

The Letter of Undertaking (LUT) is furnished in GST RFD 11 under rule 96A. The exporter declares that they would fulfil all the requirements specified under GST while exporting without making an IGST payment.

All GST registered goods and service exporters are eligible to submit LUT except the exporters who have been prosecuted for any offence, and the amount of tax evasion exceeds Rs. Two hundred fifty lakhs under the CGST Act or the Integrated Goods and Services Tax Act, 2017 or any existing laws. In such cases, where the exporter is not eligible to file LUT, they would have to furnish an export bond.

Letter of Undertaking in GST Explained in easy language.

What is LUT and why is it used?

All registered taxpayers who export the goods or services will have to furnish Letter of Undertaking (LUT) in GST RFD-11 form on the GST portal in order to make exports without payment of IGST.

When to apply/file an LUT and what was the scenario before GST?

Letter of undertaking has to be filed /submitted online before exporting the goods/services. Prior to this, exporters had to manually submit the filled and signed RFD-11 on Business letterhead in duplicate –

  • One to the Jurisdictional Deputy/Assistant Commissioner having jurisdiction over their principal place of business where the verification with the Export documents happens through ICEGATE medium
  • Another along with the Export documents to the Customs clearing authority.

Just like the earlier excise regime, this led to exporters losing considerable time and operating expense on this compliance. Eventually, this process has now been rationalized and made simple & quick, giving transparency in the entire process of exports by an exporter to all the stakeholders involved. Note that the furnishing of Bond has to be on a non-judicial stamp paper and so needs a manual submission.

What are the eligibility criteria to apply for LUT?

  • Places covered under Special Economic Zone

Document of LUT (Letter of Undertaking)

Self-declaration that the conditions of the Letter of Undertaking shall be accepted unless there is specific permission granted. In such cases, a self-declaration is required by the exporter to the effect that he has not been prosecuted should serve the purpose of notification- 37/2017- Central Tax on 4th October 2017. Verification if required may be carried out on a post-facto basis.

Time for acceptance of LUT/Bond-

As LUT or Bond is mandatory for export business, including exports to an SEZ unit, so it should be on the top priority list. The LUT/ Bond should be accepted within three working days after it has been received along with the self-declaration by the exporter as mentioned above. Failing to process the LUT within three working days, it shall be considered to be accepted.

Bank guarantee-

In all cases, bonds shall be accompanied by a bank guarantee amounting to 15% of the bond amount.

Sealing by officers-

In case of self-sealing, sealing of containers, is to be exercised under the supervision of the central excise officer having jurisdiction over the place of business. A copy of the report is to be submitted to the Deputy/ Assistant Commissioner having jurisdiction over the place of business.

Purchases from Manufacturer-

There are no provisions for issuance of CT-1 form which allows exporters to purchase goods from manufacturers without paying tax under the GST regime. The transaction between the manufacturer and the exporter is like supply, and the same would be subject to GST.

Transactions with EOUs (Export Oriented Units)-

Zero rating does not apply to supplies to EOUs, and there is no special exemption for them under the GST regime. Therefore they are taxable similar to any other taxable supplies. To the extent of exports, EOUs are eligible for zero-rating.
