Letter Of Undertaking (LUT) in GST: Format, Filing, Benefits, Eligibility, Documents Required

The Letter of Undertaking (LUT) streamlines GST for exporters by exempting them from paying taxes on exports. Discover its significance and the application process for exporters seeking tax benefits on their international trade transactions.

Letter of Undertaking (LUT):

A Letter of Undertaking (LUT) is a document that allows exporters to undertake the export of goods or services without the need to pay the Goods and Services Tax (GST) at the time of export. It is a written promise to the government that the exporter will abide by all the GST regulations and fulfil their tax liability.

Benefits of Filing LUT under GST:

  1. Cash Flow Advantage: Exporters can avoid blocking their funds in GST payments, which helps in better cash flow management.
  2. Competitive Advantage: Exports become more competitive in the international market as they are GST-free, making them more appealing to foreign buyers.
  3. Reduced Compliance Burden: Filing LUT reduces the compliance burden as it eliminates the need to claim a refund of GST paid on exports.
