SEZ (Special Economic Zone)

By Manu Rao | Updated March 2026

What Is a Special Economic Zone?

A Special Economic Zone (SEZ) is a geographically defined area within India that operates under a separate economic and customs regime. Businesses established in SEZs enjoy significant tax incentives, simplified customs procedures, and a more flexible regulatory environment — all designed to boost exports, attract foreign direct investment, create employment, and develop infrastructure.

India's SEZ programme, formalised through the SEZ Act in 2005, was inspired by China's Shenzhen model and has grown to include over 270 operational SEZs across the country. These range from massive multi-product zones spanning thousands of hectares (like the Adani Port SEZ in Mundra or the Mahindra World City in Chennai) to smaller IT/ITeS-specific zones of just 10-25 hectares.

For foreign investors, SEZs represent an attractive option for setting up export-oriented manufacturing, IT services, or processing operations — with duty-free imports, income tax holidays, and exemptions from many domestic regulations.

Legal Framework

• Special Economic Zones Act, 2005 — The primary legislation governing establishment, operation, and governance of SEZs. Key chapters cover developer requirements, unit approval process, fiscal incentives, and governance through the Board of Approval (replaced by the SEZ Authority under the 2023 amendments).
• Special Economic Zones Rules, 2006 — Detailed rules prescribing procedures for setting up SEZ units, customs clearance, DTA (Domestic Tariff Area) sales, and exit procedures.
• SEZ (Amendment) Act, 2023 — Significant amendments including the creation of "Development Hubs" for non-SEZ activities within zones, relaxation of NFE (Net Foreign Exchange) requirements, and allowing DTA sales without onerous conditions.
• Income Tax Act, 1961 — Section 10AA — Tax holiday for SEZ units: 100% exemption for first 5 years, 50% for next 5 years, and a further benefit for the next 5 years if profits are reinvested.
• Customs Act, 1962 — Section 53 and related — SEZs are treated as a separate customs territory; goods entering the SEZ are treated as exports from the DTA and are duty-free.
• FEMA provisions — 100% FDI is allowed through the automatic route for SEZ units in manufacturing. SEZ IT/ITeS units also allow 100% FDI.

Types of SEZs

Tax Benefits for SEZ Units

Income Tax (Section 10AA)

The cornerstone incentive. SEZ units that commence operations before March 31, 2020 (the original sunset clause, now extended with conditions) receive:

• Years 1-5: 100% deduction of profits and gains derived from export of goods or services
• Years 6-10: 50% deduction
• Years 11-15: 50% deduction, provided an equivalent amount is transferred to a Special Economic Zone Re-investment Reserve (and invested in specified assets within 3 years)

Important sunset clause note: Section 10AA deduction is available only to units that commenced operations on or before March 31, 2020. New units set up after this date do not get the income tax benefit (though they still get customs and other benefits). However, units in GIFT IFSC have a separate tax holiday under Section 80LA that remains in effect.

Customs Duty Exemptions

• Duty-free imports: Goods imported into the SEZ (raw materials, capital goods, consumables) are exempt from customs duty, countervailing duty, and IGST. The SEZ is a "duty-free enclave."
• Procurement from DTA: Goods procured from the Domestic Tariff Area (rest of India) are treated as deemed exports. The DTA supplier can claim GST refund or supply at zero-rated GST.

GST Treatment

• Supplies to SEZ units are zero-rated under IGST Act, 2017 (Section 16). The DTA supplier charges 0% IGST or claims a refund of input tax credit.
• SEZ units providing services entirely for export are outside the scope of domestic GST.

Other Incentives

• Stamp duty exemption: Many states exempt stamp duty on property transactions within SEZs.
• Single-window clearance: SEZ units get approvals through the Development Commissioner's office, avoiding multiple state and central agencies.
• Labour law flexibility: Some SEZs (particularly in Gujarat and Rajasthan) offer relaxed labour inspection norms, though labour laws technically still apply.

Net Foreign Exchange (NFE) Requirement

SEZ units must be net positive foreign exchange earners over a 5-year cumulative period (Block Assessment). This means:

NFE = Exports - Imports (CIF value of all imports including capital goods)

This requirement was relaxed under the 2023 amendments for certain categories, and the Development Commissioner has discretion to allow temporary negative NFE during the initial setup period. However, the fundamental export orientation requirement remains — SEZ units must export goods or services and cannot primarily serve the domestic market.

Setting Up an SEZ Unit: Process

1. Choose the SEZ: Select an operational SEZ that matches your sector and location requirements. Most SEZ developers offer built-to-suit or ready-to-move options.
2. Apply for Letter of Approval (LoA): Submit Form F to the Development Commissioner of the relevant SEZ. The application includes the project report, projected exports, employment, investment, and NFE computation.
3. Approval by Unit Approval Committee (UAC): The UAC (chaired by the Development Commissioner) reviews the application and grants the LoA, typically within 15-30 days.
4. Execute the lease/licence agreement: Enter into a lease or licence agreement with the SEZ developer for the land/built-up space.
5. Incorporate the entity: SEZ units are typically set up as separate legal entities (Private Limited Companies or LLPs). Many foreign investors create a separate Indian subsidiary specifically for the SEZ operations.
6. Obtain customs bonding: The SEZ unit's premises are customs-bonded. All goods entering and leaving are documented through the SEZ Online system.
7. Commence operations: Within the timeline specified in the LoA (typically 1-3 years for manufacturing, shorter for services).

How This Affects Foreign Investors in India

Export-Oriented Manufacturing

A foreign manufacturer wanting to set up an Indian factory to serve global markets (e.g., auto components, electronics, pharmaceuticals) should evaluate the SEZ option. Benefits include duty-free import of machinery and raw materials, zero-rated GST on procurement, and (for pre-2020 units) income tax holiday. Even post-sunset, the customs benefits alone can save 10-25% on input costs.

IT/ITeS Operations

India's IT services boom was significantly catalysed by IT SEZs. Companies like Infosys, TCS, Wipro, and hundreds of foreign captive centres operate from IT SEZs. For a foreign company setting up a captive software development centre, the SEZ provides duty-free import of computing equipment, zero-rated GST on infrastructure, and simplified regulatory compliance.

SEZ vs. DTA Decision

Not every foreign investor should choose an SEZ. Key considerations:

Interaction with FDI Rules

100% FDI under the automatic route is allowed for SEZ units in manufacturing and services. The investment is reported through the normal FC-GPR route. Sectoral caps and conditions that apply to DTA investments also apply in SEZs (e.g., if a sector is under the government approval route in DTA, the same applies in the SEZ).

SEZ Challenges and Evolving Policy

The SEZ policy has faced criticism and undergone significant evolution:

• Sunset of income tax benefit: The Section 10AA sunset clause (March 31, 2020 for new units) reduced the attractiveness of SEZs for new investments. The government chose not to extend it, viewing the tax holiday as inconsistent with the broader shift to lower corporate tax rates (22-25%) under Section 115BAA/BAB.
• De-notification wave: Several approved SEZs have been de-notified because developers could not attract sufficient units. Land locked up in non-operational SEZs became a policy issue.
• Development Hubs (2023 amendments): The 2023 amendments allow SEZ developers to convert underutilised land into "Development Hubs" that can accommodate non-export activities (domestic manufacturing, commercial offices, residential). This addresses the land utilisation problem while preserving the SEZ framework for export-oriented units.
• Competition with PLI: The Production Linked Incentive scheme has emerged as the government's primary tool for attracting manufacturing investment, partially replacing SEZs in the policy toolkit.

Common Mistakes

• Setting up in an SEZ when primary sales will be domestic. The NFE requirement means SEZ units must be net foreign exchange positive. If your Indian subsidiary will primarily serve the Indian market, an SEZ is the wrong choice — you will face customs duties on every DTA sale, negating the import duty benefit.
• Assuming new units still get the income tax holiday. The Section 10AA benefit is not available for units commencing after March 31, 2020. New units get customs and GST benefits, but not the income tax deduction. Evaluate whether the remaining benefits justify the additional compliance burden.
• Ignoring the DTA sale duty impact. When an SEZ unit sells to the domestic market, it must pay customs duty and IGST on the DTA clearance — as if the goods were being imported into India. For units with even 20-30% domestic sales, this can erode the entire SEZ advantage.
• Not planning for NFE monitoring. The Development Commissioner monitors NFE compliance through the SEZ Online portal. Units that are not NFE positive by the end of the 5-year block face potential exit from the SEZ, with recovery of foregone duties and taxes. Plan export ramp-up carefully.
• Overlooking the operational compliance. SEZ units operate under customs bonding — every item entering or leaving the unit is logged. This means stricter inventory management, customs documentation, and periodic audits by the Development Commissioner's office. Budget for dedicated SEZ compliance personnel.

Practical Example

PrecisionParts GmbH, a German manufacturer of precision-engineered automotive components, wants to set up an Indian factory to serve its global OEM customers (BMW, Mercedes, Toyota). The company evaluates two options:

Option A: SEZ Unit in Mahindra World City, Chennai

• Duty-free import of CNC machines (value: INR 25 crore, duty saved: ~18% = INR 4.5 crore)
• Duty-free import of specialty steel and alloys (annual: INR 15 crore, duty saved: ~10% = INR 1.5 crore/year)
• Zero-rated GST on domestic procurement (electricity, consumables)
• No income tax benefit (new unit, post-2020)
• NFE requirement: 90% of production must be exported (matches the plan)

Option B: DTA Unit in SIPCOT Industrial Park, Oragadam

• Full customs duty on imported machines (INR 4.5 crore)
• Full duty on imported steel (INR 1.5 crore/year)
• GST input credit available on domestic procurement
• No export obligation — can sell 100% domestically if needed
• RoDTEP benefit of ~2% on FOB exports
• Eligible for PLI (if the auto component category is notified)

Decision: PrecisionParts chooses the SEZ because 95% of production will be exported, and the duty savings on imported machines and raw materials (INR 4.5 crore upfront + INR 1.5 crore annually) far exceed the RoDTEP benefit foregone (~INR 60 lakh/year on estimated exports of INR 30 crore). The company sets up PrecisionParts India Pvt Ltd as a wholly owned subsidiary, invests INR 50 crore through the FDI automatic route, and obtains the SEZ Letter of Approval within 3 weeks.

Key Takeaways

• SEZs are duty-free enclaves designed for export-oriented businesses — imports are customs-free, GST is zero-rated, and a 10AA tax holiday applies to pre-2020 units
• India has 270+ operational SEZs, including multi-product, sector-specific, IT/ITeS, and free trade warehousing zones
• The income tax holiday (Section 10AA) is no longer available for new units commencing after March 31, 2020
• SEZ units must maintain net positive foreign exchange over a 5-year block
• DTA sales by SEZ units attract full customs duty and GST — making SEZs unsuitable for domestic-market-focused businesses
• 100% FDI is allowed under the automatic route for SEZ units
• 2023 amendments introduced Development Hubs, allowing non-export activities in underutilised SEZ land
• Compare SEZ benefits against DTA + RoDTEP + PLI to determine the optimal structure
