Charging IGST Instead of CGST+SGST on Zero-Rated Supplies Introduction Zero-rated supplies under GST are an important concept. Especially for exporters & businesses dealing with SEZ units . People usually get confused about which tax to apply. Should it be IGST or CGST & SGST ? This article explains the correct approach. It also helps you understand why IGST is used & how the rule works in real situations. It is important to know this because even small mistakes can lead to wrong tax filing & delays in refund. This article explains why IGST is charged instead of CGST & SGST on zero-rated supplies under GST.
What Are Zero-Rated Supplies? Zero-rated supplies are special types of supplies under GST. These supplies attract 0% tax. But they are still considered taxable. As per the GST law, zero-rated supplies include:
Export of goods Export of services Supply to SEZ units Supply to SEZ developers These are defined under Section 16 of the IGST Act. Though the tax rate is zero but businesses can still claim Input Tax Credit (ITC). This is an important benefit.
Why IGST Is Used for Zero-Rated Supplies Zero-rated supplies are treated as inter-state supplies. This is the key reason. Under GST rules:
Inter-state supply → IGST is charged Intra-state supply → CGST + SGST is charged Exports and SEZ supplies are always treated as inter-state. So IGST applies automatically. CGST and SGST are not used because of this rule. Only IGST is relevant. This ensures uniform tax treatment across India.
Legal Provision Behind This Rule The rule comes from Section 16 of the IGST Act. According to the law, zero-rated supplies fall under the IGST framework. They are eligible for refund benefits. They can be made with or without tax. The law gives two options to taxpayers:
Supply with payment of IGST Supply without payment using LUT or bond This is why IGST is the only tax connected with zero-rated supplies.
Two Methods of Making Zero-Rated Supplies Supply With Payment of IGST In this method, tax is charged first. IGST is charged on the invoice . Tax is paid to the government. Later, a refund is claimed. This method is simple but blocks working capital.
Supply Without Payment of IGST (LUT/Bond) In this method, no tax is charged. No IGST is paid. LUT or bond is required. Refund of ITC is claimed. This method is more commonly used. It avoids cash blockage.
Why CGST and SGST Are Not Charged CGST and SGST apply only to intra-state supplies. But zero-rated supplies are not intra-state. Exports and SEZ supplies are treated as inter-state by default. Because of this CGST is not applicable and SGST is not applicable. Only IGST applies. Also, the GST law does not allow charging both IGST and CGST+SGST together. Only one type of tax can be charged at a time.
Benefits of Charging IGST on Zero-Rated Supplies Charging IGST (or following the IGST route) provides several benefits:
Easy refund process Uniform tax structure No double taxation Better compliance Smooth interstate transactions Also, exporters can stay competitive in global markets because the GST burden is removed.
Refund Mechanism in Zero-Rated Supplies Refund is a key feature of zero-rated supplies. There are two types of refunds:
Refund of IGST Paid
If IGST is paid:
Full IGST can be claimed as a refund Refund of Unutilized ITC
If LUT is used:
ITC on inputs can be claimed Refunds are usually processed in stages. Around 90% may be given quickly and the rest after verification.
Common Mistakes to Avoid Many people make mistakes when they apply for GST on zero-rated supplies. Common mistakes include charging CGST & SGST instead of IGST. Not filing LUT before export. Not claiming a refund properly. Treating zero-rated supply as exempt supply.
Zero-rated & exempt supplies are different. In exempt supplies, ITC cannot be claimed. But in zero-rated supplies, ITC is allowed.
Example for Better Understanding Suppose a company in India exports goods to the USA. It is a zero-rated supply in this case. It is treated as inter-state and IGST applies. Now the company has two choices, charge IGST and claim a refund or use LUT and not charge IGST. But it cannot charge CGST and SGST.
Conclusion Charging IGST instead of CGST and SGST on zero-rated supplies is a basic GST rule. It is based on the concept of inter-state supply. Exports and SEZ supplies always fall under this category. The law clearly allows two options. Businesses can either pay IGST and claim a refund or supply without tax using LUT. Understanding this rule is necessary for correct GST compliance. It helps avoid errors & ensures smooth refund processing.
