Introduction
Special Economic Zones (SEZs) play an important role in India’s economic development. They were established to promote exports, attract domestic and foreign investment, generate employment, encourage manufacturing, and strengthen India’s position in international trade. The objective behind creating these zones was to provide businesses with a favourable operating environment, simplified procedures, and tax benefits that would help them compete in global markets.
The Special Economic Zones Act, 2005, provides the legal framework for establishing and operating SEZs in India. Under this framework, eligible businesses can enjoy specified fiscal benefits for approved activities, commonly known as authorised operations.
However, the introduction of the Goods and Services Tax (GST) on 1 July 2017 changed the way many transactions involving SEZs were handled. Although the GST framework continued to recognise zero-rated supplies to SEZ units and developers, businesses began facing practical difficulties relating to tax refunds, documentation, authorised operations, reverse charge mechanism (RCM), and the treatment of certain transactions.
Over time, these issues resulted in disputes between taxpayers and tax authorities. Courts and appellate authorities have addressed several important questions, but uncertainty continues in areas where comprehensive clarification is needed.
This article explains the GST provisions applicable to SEZ transactions, the challenges faced by businesses, relevant judicial developments, and possible reforms that could improve the effectiveness of India’s SEZ framework.
1. What Is a Special Economic Zone?
A Special Economic Zone is a specifically designated area established to promote economic activity, particularly exports, investment, and employment. The SEZ Act, 2005, provides the framework for establishing these zones and regulating the activities carried out within them.
Businesses operating in SEZs may receive certain tax and customs benefits, subject to applicable legal provisions and the conditions governing their authorised operations.
The main objectives of SEZs include:
- Promoting exports of goods and services.
- Attracting domestic and foreign investment.
- Encouraging industrial development and manufacturing.
- Creating employment opportunities.
- Improving infrastructure and logistics.
- Simplifying procedures for eligible businesses.
- Strengthening India’s competitiveness in international markets.
For example, a company manufacturing electronic components in an approved SEZ may import eligible machinery and raw materials under applicable customs exemptions. It may also procure goods and services from domestic suppliers under the GST zero-rating framework, provided the relevant legal and procedural conditions are satisfied.
However, the benefits available to an SEZ are not unlimited. Businesses must comply with the applicable provisions of the SEZ Act, GST legislation, customs law, and relevant notifications.
2. Legal Relationship Between the SEZ Act and GST Laws
The SEZ Act, 2005, and the GST laws operate together to determine the tax treatment of transactions involving SEZ units and developers.
Section 26 of the SEZ Act provides specified exemptions and benefits for authorised operations. Section 51 gives the SEZ Act overriding effect over inconsistent provisions of other laws, subject to the scope of the statutory provisions involved.
Under GST, the definition of a Special Economic Zone refers to the meaning assigned to it under the SEZ Act. Therefore, the status of an entity as an SEZ unit or developer must be determined with reference to the applicable SEZ framework.
The Central Goods and Services Tax (CGST) Act also requires separate GST registration for an SEZ unit or developer and a place of business outside the SEZ in the same state, subject to the applicable registration provisions.
Example
Suppose ABC Limited operates two establishments in Gujarat:
- One manufacturing unit in the Domestic Tariff Area (DTA).
- Another unit in an approved SEZ.
Even though both establishments belong to the same company, they generally require separate GST registrations. Transactions between them must be examined under the GST provisions applicable to distinct persons.
This distinction is important because a company cannot automatically treat the two establishments as a single GST registration merely because they share the same legal ownership.
A continuing challenge is that certain provisions of the SEZ Act retain references to earlier indirect taxes, such as central excise duty and service tax. Since GST replaced several of these taxes, legislative alignment is necessary to avoid uncertainty about the interaction between older SEZ provisions and the current tax system.
3. Zero-Rated Supplies Under GST
One of the most important features of the GST framework for SEZ transactions is the concept of zero-rated supply.
Section 16 of the Integrated Goods and Services Tax (IGST) Act, 2017, covers exports of goods or services and supplies of goods or services to an SEZ developer or unit for authorised operations.
Zero rating is different from an ordinary GST exemption. Under the zero-rating framework, eligible businesses can generally retain input tax credit, subject to the applicable conditions, and claim a refund through the prescribed procedure.
This helps prevent GST from becoming an additional cost in export-oriented business activities.
Example of a zero-rated supply
Suppose XYZ Enterprises, a supplier registered in Gujarat, supplies machinery worth ₹10,00,000 to an SEZ unit for its authorised manufacturing operations.
If the transaction satisfies the applicable conditions for zero rating, XYZ Enterprises may supply the machinery under a valid Letter of Undertaking (LUT) without payment of IGST and claim a refund of eligible unutilised input tax credit.
Alternatively, payment of IGST followed by a refund may be available where the applicable law and notifications permit that route.
The supplier must maintain the necessary invoices and supporting documents and comply with the prescribed endorsement and refund requirements.
Important: Zero rating does not mean that every purchase made by an SEZ unit automatically qualifies for tax-free treatment. The supply must satisfy the relevant legal conditions, including the requirement that it be for authorised operations.
4. What Are Authorised Operations?
Authorised operations are activities approved for an SEZ unit or developer under the applicable SEZ framework.
This condition is important because the availability of GST benefits may depend on whether the goods or services are genuinely connected with the approved activities.
For example, a pharmaceutical company operating in an SEZ may procure laboratory equipment, manufacturing machinery, professional services, and maintenance services for its approved operations.
However, a purchase unrelated to its authorised activities may not automatically qualify for the same tax treatment.
Businesses should therefore maintain:
- Their Letter of Approval and relevant amendments.
- Records identifying the approved authorised operations.
- Purchase orders and tax invoices.
- Evidence of receipt and use of goods or services.
- Endorsements required from the appropriate SEZ officer.
- Documents supporting the refund claim.
A supplier should also verify the nature of the transaction before issuing an invoice under the zero-rating provisions.
Clear documentation can help reduce disputes and avoid the rejection or delay of refund claims.
5. GST Refunds and the Compliance Challenges Faced by Suppliers
Refunds are one of the most significant practical issues affecting SEZ transactions.
A domestic supplier making an eligible zero-rated supply may choose to supply under an LUT without payment of IGST and claim a refund of eligible unutilised input tax credit, subject to the applicable law.
However, the refund process involves documentation, prescribed forms, and compliance with the conditions laid down in the CGST Rules.
Rule 89 of the CGST Rules governs the procedure for refund applications. Depending on the nature of the claim, the supplier must furnish the relevant statements and supporting records.
Common difficulties include:
- Delays in obtaining the necessary endorsement from the SEZ authorities.
- Disputes about whether the goods or services relate to authorised operations.
- Differences in the interpretation of refund eligibility.
- Mismatches between invoices, returns, and supporting documents.
- Refund applications being questioned because of procedural requirements.
- Uncertainty about the respective refund rights of suppliers and SEZ units.
These issues can affect working capital, particularly for smaller businesses that regularly supply goods or services to SEZ units.
Example of a refund dispute
Suppose a registered supplier purchases raw materials and pays ₹1,80,000 as eligible input tax credit. The supplier then makes qualifying zero-rated supplies to an SEZ unit under an LUT without charging IGST.
If the supplier satisfies the legal requirements, the eligible unutilised input tax credit may be refundable.
However, if the required endorsement is delayed or the tax department questions whether the supplies relate to authorised operations, the refund may remain pending.
The supplier may have already paid its own vendors, while the refund remains blocked. This creates a financial burden even though the underlying transaction may qualify for zero rating.
For this reason, a predictable refund process is essential to the success of the SEZ framework.
6. Can an SEZ Unit Claim a Refund of Unutilised Input Tax Credit?
Another important legal question concerns refund claims filed by SEZ units themselves.
An SEZ unit may procure goods and services on which GST has been charged and accumulate eligible input tax credit. It may subsequently make zero-rated supplies, including exports, without payment of IGST under an LUT.
The question arises whether the unit can claim a refund of its accumulated credit under Section 54 of the CGST Act, read with Section 16 of the IGST Act and the applicable rules.
Disputes have arisen because the department and taxpayers have interpreted certain refund provisions differently, particularly where the rules address supplies made to an SEZ unit and declarations concerning the credit claimed by the recipient.
Courts have considered whether procedural restrictions intended to prevent duplicate refunds can be used to deny legitimate refunds relating to zero-rated supplies made by an SEZ unit.
The outcome depends on the facts of the case, the nature of the credit, and the applicable statutory provisions and judicial decisions.
Practical example
An SEZ unit exports software services to customers outside India. It pays GST on eligible domestic purchases of software licences, professional services, and other business inputs.
Because the unit makes zero-rated exports under an LUT, it may accumulate eligible input tax credit.
If the credit cannot be utilised against its other tax liabilities, the unit may seek a refund under the applicable provisions.
If the refund is rejected solely because of a procedural interpretation that does not apply to the particular transaction, the unit may challenge the decision through the available legal remedies.
Businesses should examine the precise facts and applicable judgments before filing or contesting such claims.
7. Reverse Charge Mechanism and SEZ Units
The reverse charge mechanism is another area that has generated questions in the SEZ sector.
Under reverse charge, the recipient rather than the supplier is responsible for paying GST on specified categories of supplies, as provided under the law.
The difficulty arises when an SEZ unit receives services that fall within a reverse charge notification but are also claimed to be connected with its authorised operations.
For example, a unit may receive legal services, goods transport services, security services, or other notified services.
The question is whether the unit must pay GST under reverse charge or whether the zero-rating and exemption provisions applicable to authorised SEZ operations affect the tax liability.
The answer must be determined by considering the relevant provisions of the IGST Act, applicable notifications, the nature of the service, and the legal status of the recipient.
Advance rulings have addressed aspects of this issue, including disputes involving Portescap India and Waaree Energies. However, an advance ruling generally has limited binding effect under the statutory framework and should not automatically be treated as universally applicable to every SEZ unit.
Example
An SEZ manufacturing unit receives legal services from an advocate for a matter directly related to its authorised operations.
If the service falls within a notified reverse charge category, the unit should examine the relevant notification and any applicable exemption or clarification before determining whether GST is payable.
The unit should not assume that all services received by an SEZ are automatically exempt merely because they relate to its business.
Similarly, a supplier should not assume that reverse charge necessarily applies without considering the specific legal provisions governing the transaction.
Clear and consistent guidance from the tax authorities would help businesses determine their obligations without repeatedly resorting to litigation.
8. Supplies From an SEZ to the Domestic Tariff Area
The GST treatment of transactions moving from an SEZ to the Domestic Tariff Area differs depending on whether the transaction involves goods or services.
Supply of goods
Under Section 30 of the SEZ Act, goods removed from an SEZ into the DTA are subject to applicable customs duties, subject to the relevant legal provisions and exemptions.
The transaction is generally handled through the customs clearance procedure, and the DTA buyer may need to file a bill of entry and pay the applicable duties, including IGST where payable.
The buyer may claim input tax credit of eligible IGST paid on importation, subject to the conditions under the GST law.
Supply of services
Services supplied by an SEZ unit to a domestic customer must be analysed separately.
For example, if an IT company operating in an SEZ provides software development services to an Indian customer located outside the zone, the transaction must be evaluated under the applicable place-of-supply and IGST provisions.
The fact that the service provider is located in an SEZ does not automatically make every domestic service a tax-free supply.
Example
An SEZ unit manufactures electronic components and sells finished goods to a buyer in the DTA.
The buyer must follow the applicable customs clearance procedure and pay the duties legally payable on the goods.
If the same SEZ unit separately provides technical consultancy services to the buyer, the tax treatment of those services must be determined under the GST provisions applicable to the service transaction.
Businesses should avoid treating goods clearances and service supplies as identical transactions.
9. Compensation Cess and the Need for Legislative Clarity
Another issue concerns the availability of exemptions from compensation cess in relation to goods imported into or used within an SEZ.
An SEZ’s duty-free status does not necessarily exempt every levy imposed under a separate statute. The availability of relief depends on the wording of the relevant legislation, customs notifications, and other applicable provisions.
This distinction can create difficulties where a business assumes that a general SEZ exemption automatically covers a particular cess.
For example, an SEZ unit importing coal or another industrial input may claim that its SEZ status entitles it to an exemption from a particular levy. The claim must be tested against the precise statutory provisions governing that levy.
Where the legislation does not clearly provide the exemption, the issue may require judicial interpretation or legislative amendment.
This demonstrates why the SEZ Act and the GST framework should be reviewed together. Clear statutory language can prevent disputes and help investors calculate their tax costs before making long-term business decisions.
10. The Role of Circulars and Administrative Clarifications
Circulars and administrative instructions are important because they explain how tax authorities should apply the law in recurring situations.
However, businesses dealing with SEZ transactions have encountered questions relating to endorsements, authorised operations, refunds, reverse charge, and reporting requirements that may not be resolved by a single general clarification.
For instance, Circular No. 48/22/2018-GST, dated 14 June 2018, addressed specific issues relating to supplies of services to SEZ units and developers.
Circular No. 125/44/2019-GST, dated 18 November 2019, provided broader guidance on GST refunds, including procedural matters relevant to eligible claims.
Such guidance is useful, but circulars cannot replace statutory provisions or override binding judicial decisions.
A comprehensive review of SEZ-related GST procedures could help resolve recurring practical questions, including:
- What documents should be accepted as sufficient evidence of authorised operations?
- How should endorsements be issued and communicated to suppliers?
- How should legitimate refund claims of SEZ units be handled?
- What is the treatment of specified services under reverse charge?
- How should transactions between different SEZ units be reported?
- How should temporary movements of goods be coordinated with applicable GST and customs procedures?
Consistent guidance would reduce administrative differences between zones and help taxpayers comply with the law more efficiently.
11. Why SEZ Policy Reform Is Necessary
The SEZ framework was designed to provide a stable environment for export-oriented businesses. However, tax benefits alone cannot guarantee the success of these zones.
Businesses also require predictable rules, efficient administration, timely refunds, reliable infrastructure, and clarity about domestic sales and authorised operations.
The policy discussion surrounding the proposed Development of Enterprises and Services Hubs (DESH) framework reflects the broader question of how India should modernise its export-oriented industrial zones.
Any reform should consider the changing requirements of manufacturing, technology services, global supply chains, and international trade.
The government can improve the operating environment through measures such as:
- Clarifying refund eligibility: Provide consistent guidance on refunds of eligible unutilised input tax credit and the application of relevant refund restrictions.
- Simplifying endorsements: Develop an efficient digital process for recording and verifying supplies made for authorised operations.
- Clarifying reverse charge: Issue comprehensive guidance on the interaction between zero rating, exemptions, and notified reverse charge liabilities.
- Updating the SEZ Act: Review provisions referring to earlier indirect taxes and align them with the present GST and customs framework.
- Improving coordination: Establish better coordination between GST authorities, customs officials, and SEZ administrations.
- Reducing unnecessary litigation: Encourage consistent implementation of judicial decisions and address recurring legal uncertainties through appropriate administrative or legislative measures.
These reforms would not necessarily require introducing new tax incentives. In many cases, better administration and clear legal drafting could produce substantial benefits.
Conclusion
Special Economic Zones continue to be an important part of India’s export and investment strategy. The GST framework recognises the importance of eligible supplies to SEZ units and developers by providing zero-rating treatment for authorised operations.
However, the practical effectiveness of this framework depends on more than the wording of the law. Businesses also need a reliable refund system, consistent treatment of authorised operations, clarity regarding reverse charge liabilities, and coordination between the various authorities responsible for implementing the rules.
Judicial decisions have helped resolve several disputes, particularly those involving refund eligibility and the interpretation of procedural restrictions. Nevertheless, litigation should not become the normal method of obtaining clarity on routine business transactions.
For example, a domestic supplier delivering machinery to an SEZ should be able to determine the correct tax treatment without prolonged uncertainty about endorsements and refund eligibility. Likewise, an SEZ unit exporting services should be able to understand its refund rights and compliance obligations through clear statutory provisions and administrative guidance.
The way forward is to strengthen coordination between the SEZ and GST frameworks, modernize outdated provisions, simplify documentation, and provide consistent guidance to taxpayers.
