Do you want to make your export business hassle-free? A GST LUT Form (Letter of Undertaking) allows you to carry out export transactions without paying Integrated Goods and Services Tax (IGST) at the time of supply. By obtaining this document, exporters can focus on their core business operations without worrying about tax-related obstacles, making the export process more seamless and efficient.
The GST LUT Form is a crucial requirement for businesses engaged in international trade, helping them maintain steady cash flow and avoid unnecessary tax payments upfront. Generally, the LUT is valid for one financial year and must be renewed at the beginning of each new financial year to continue enjoying these benefits.
The process for filing the GST LUT Form is entirely online, making it accessible to all eligible exporters across India. At Corpbiz, our team of seasoned professionals provides end-to-end assistance to ensure a smooth, error-free process for obtaining your GST LUT Form and other GST-related services.


A GST LUT form is a powerful tool for exporters, enabling them to conduct hassle-free transactions without paying Integrated Goods and Services Tax (IGST) at the time of supply. Typically, it allows exporters to engage in the export of goods or services without the obligation of immediate tax payment.
It is mandatory for all the registered taxpayers engaged in the export of goods or services to provide a Letter of Undertaking (LUT) using the GST RFD-11 form on the GST portal. Typically, it is used to facilitate the export of goods and services without the burden of paying Integrated GST (IGST) upfront. It helps exporters to avoid the liquidity crunch that might arise from paying taxes first and then waiting for refunds. It also helps taxpayers to reduce the administrative burden associated with claiming refunds, thereby saving time and resources.
The list of advantages of filing GST LUT form is as follows:

By obtaining a GST LUT Form, exporters can carry out their export transactions without paying tax upfront. Without an LUT, exporters must pay taxes initially and later claim refunds for zero-rated exports, which can delay the process.
With an LUT Certificate, exporters can avoid the complex procedures of claiming tax refunds and following up with tax authorities. This simplifies compliance and saves significant time and effort.
The LUT Certificate helps exporters keep their working capital free, instead of locking funds in tax payments. This is especially beneficial for small and medium-sized enterprises (SMEs) that often face cash flow challenges.
Once obtained, the LUT remains valid for the entire financial year. Regular exporters no longer need to file repeated applications, allowing them to focus on core business activities without administrative interruptions.
Exporters with LUT certificates can offer more competitive pricing in the international markets since they are no longer burdened by the upfront tax cost. It is one of the benefits of filing GST LUT Form.
It also eliminated the traditional requirement for seeking tax refunds, thus saving considerable time and administrative effort.
