Supply by and to SEZ Under GST: Understanding the Tax Implications

Under the GST regime, supply to and by SEZ units are treated with special tax treatment in order to encourage exports and investments. Supplies to SEZs are treated as zero-rated, so that the suppliers can either export goods and services without any GST under LUT or pay IGST and claim refund. Conversely, imports by SEZ units to DTA are regarded as imports; the recipient, therefore, shall pay IGST under RCM. The input tax credit would also be admissible to the SEZ unit on inward supplies used in authorized operations. Thus, these provisions help SEZ businesses reduce the tax burden and improve cash flows, making them globally competitive. In this blog, we will explore:

What is an SEZ Under GST?

A Special Economic Zone (SEZ) is a designated area with special tax and business incentives to boost trade and economic activities. The GST Act classifies SEZ units and SEZ developers separately and provides them with distinct tax benefits.Sez GST Rules The GST rules for Special Economic Zones (SEZs) provide substantial tax benefits to encourage export-oriented businesses. SEZ units are exempt from GST on exports, and they can claim refunds on input tax credits for goods and services used in export activities.

Supplies from the Domestic Tariff Area (DTA) to SEZs are treated as deemed exports, and DTA suppliers can also claim input tax credit refunds. Therefore, the developers of SEZ can not get GST on infrastructure development and also become eligible for input tax refunds. In general, the GST exemption to SEZ works to improve their competitiveness in international trade.
