Korea Free Economic Zone Affiliate Facility Sharing 2026: What Foreign-Invested Companies Should Plan

Table of Contents

Why FEZ Facility Sharing Matters in 2026

Korea’s Free Economic Zones (FEZs) have always been attractive for foreign manufacturers, logistics operators, R&D centers, and regional headquarters. The usual selling points are familiar: serviced industrial land, local government support, access to ports or airports, and a more investment-friendly administrative environment than a standard industrial site.

But one practical problem has often remained: global groups rarely expand one Korean entity at a time.

A foreign investor may first establish a Korean manufacturing subsidiary, then add a Korean sales company, an R&D affiliate, a warehousing entity, or a joint venture with a strategic partner. In many projects, the first FEZ tenant signs the land or facility contract, builds the initial site, and later discovers that an affiliated foreign-invested company also needs to use part of the same premises. If the rules are too rigid, the group may need a second lease, duplicated facilities, or a new site search even when the original site has unused capacity.

That is why a 2026 policy direction from Korea’s Ministry of Trade, Industry and Energy (MOTIE) is important. MOTIE has announced that relevant laws will be amended to allow a foreign-invested company in a Korean Free Economic Zone to rent out a site or facilities to an affiliate foreign-invested company. For foreign groups, this can make FEZ planning more flexible—but only if the structure is prepared carefully from the beginning.

This guide explains what the change means, where the risks sit, and how foreign investors should structure FEZ affiliate facility sharing in 2026.

The 2026 Policy Change in Plain English

The key concept is simple: a foreign-invested company located in a Korean FEZ may be permitted to lease or sublease part of its site or facilities to an affiliated foreign-invested company.

In practice, this could support arrangements such as:

• A manufacturing subsidiary sharing warehouse space with a Korean distribution affiliate
• A biotech production entity allowing an R&D affiliate to use laboratory or office areas
• A logistics subsidiary allocating part of a FEZ facility to an e-commerce fulfillment affiliate
• A foreign parent group separating regulated and non-regulated functions between Korean subsidiaries
• A joint venture using shared utilities, docks, clean rooms, testing equipment, or administrative offices

This is not the same as saying that any tenant can freely sublease FEZ land. FEZ sites are usually subject to designated-use restrictions, tenant eligibility requirements, investment commitments, and approvals from the FEZ authority or local government. The announced direction is a liberalization, not a blank check.

Foreign investors should therefore treat the change as a planning opportunity: it may allow more efficient group structuring, but the actual implementation will depend on the amended law, enforcement decrees, lease terms, FEZ authority approval, and the specific business activities of each affiliate.

Why Foreign-Invested Groups Need This Flexibility

Many foreign investors start with one Korean entity because it is administratively simpler. After market entry, however, the business model often becomes more complex.

For example, a foreign manufacturer may incorporate a Korean subsidiary to qualify as a foreign-invested company, lease land in an FEZ, import capital goods, and build a production line. Two years later, the group may decide that the Korean sales operation should be separated for transfer pricing, distribution licensing, or customer-contract reasons. The sales entity may need a registered address, showroom, storage space, or employee office near the plant. Without an affiliate sharing route, the group could face unnecessary duplication.

A facility sharing framework can reduce friction in three ways:

1. Lower setup cost by avoiding duplicate leases and construction
2. Faster operational launch because the affiliate can use existing infrastructure
3. Cleaner group governance because functions can be separated legally while remaining physically coordinated

What Counts as an Affiliate?

The exact definition will need to be checked under the amended rules, but foreign investors should expect Korean authorities to look at real ownership and control rather than labels.

An affiliate may include:

• A company controlled by the same foreign parent
• A subsidiary of the Korean FEZ tenant
• A sister company under the same global group
• A joint venture where the foreign investor has meaningful ownership or control
• Another Korean foreign-invested company with a legally documented group relationship

Before relying on affiliate sharing, foreign investors should prepare a clear ownership chart showing:

• The foreign parent company
• Each Korean entity
• Shareholding percentages
• FDI notification and registration status
• Representative directors
• Business registration numbers
• The intended use of the shared premises

This ownership chart should match bank records, FDI filings, corporate registry records, and tax documents. Inconsistent group documentation is one of the easiest ways to delay approval.

Structuring Options for FEZ Facility Sharing

There is no single structure that fits every project. The right answer depends on the lease, industry, tax model, employment plan, and future financing needs.

Key Legal Questions Before Signing

Foreign investors should not wait until after construction to ask whether affiliate sharing is possible. The question should be raised during site selection and lease negotiation.

1. Does the FEZ Lease Permit Subleasing?

Many industrial land or facility contracts restrict assignment, subleasing, and third-party use. Even if the law allows affiliate sharing, the actual lease may still require written consent.

Ask for the sublease clause, approval procedure, required documents, review timeline, and whether rent can be charged at market value.

2. Is the Affiliate’s Business Activity Permitted?

FEZ approvals are often tied to industry categories, investment plans, employment commitments, and facility use. A battery-materials manufacturing site may not automatically allow unrelated e-commerce storage or general office leasing.

The affiliate’s Korean Standard Industrial Classification (KSIC) codes, business registration, and actual use of the premises should align with the FEZ development plan.

3. Will the Arrangement Affect Incentives?

Some FEZ incentives depend on qualified investment amount, employment, technology, exports, or designated industry activity. If the tenant shares space with an affiliate, the authority may ask how investment, employees, equipment, and revenue are allocated.

Poor documentation could weaken an incentive claim or create clawback risk.

4. Is a Separate Business License Needed?

Certain activities require separate permits or registrations, such as food import, cosmetics responsible seller registration, medical device import, hazardous materials storage, logistics, telecommunications, or payment services. Physical sharing does not eliminate licensing requirements.

5. How Will Rent and Costs Be Priced?

If related companies charge rent, utilities, staff support, or equipment-use fees, Korea’s tax authorities may review whether the pricing is arm’s length. Foreign groups should prepare a simple transfer pricing rationale even for domestic Korean affiliates, especially if cross-border service fees or royalties also exist.

FDI Notification and Corporate Registration Issues

A common mistake is assuming that a facility-use arrangement is only a real estate issue. For foreign-invested companies, it can also affect FDI records and corporate registrations.

Each Korean entity should check whether its registered address, place of business, and actual operating location are consistent. If the affiliate uses the FEZ premises as its principal office or branch location, business registration updates may be needed. If the affiliate was incorporated with a virtual office or temporary address, moving into the FEZ facility may require National Tax Service updates and bank notification.

For D-8 visa planning, the issue becomes even more sensitive. Immigration officials often look for evidence of real business operations. A shared facility can support substance, but only if the documentation clearly shows that the visa applicant’s company has legitimate access, desks or work areas, employees, operations, and authority to conduct business there.

Tax and Accounting Treatment

FEZ affiliate facility sharing should be recorded properly from the first invoice.

If the master tenant charges rent, the payment may be subject to Korean VAT unless a specific exemption applies. Utility reimbursements, management fees, equipment-use charges, and shared employee costs should be separately described. Lumping everything into an undocumented monthly “support fee” can create problems later.

For accounting purposes, companies should decide whether the arrangement is a lease or service contract, how VAT invoices will be issued, and how common costs will be allocated.

A practical approach is to maintain a monthly allocation schedule. The schedule can show square meters used, headcount, equipment hours, utilities, and any shared staff time. It does not need to be overly complicated, but it should be consistent and defensible.

Compliance Checklist for Foreign Investors

Before an affiliate starts using a FEZ site or facility, prepare the following:

• Confirm the amended legal basis and local FEZ authority guidance
• Review the master lease, occupancy permit, and designated-use restrictions
• Confirm both entities’ foreign-invested company status
• Prepare an ownership chart and group relationship evidence
• Check whether the affiliate’s KSIC codes match the intended activity
• Obtain written consent from the landlord, FEZ authority, or management agency if required
• Sign a bilingual sublease, facility-use, or cost-sharing agreement
• Update business registration address or branch records if needed
• Confirm VAT invoice treatment and related-party pricing
• Check industry-specific permits before moving inventory, equipment, or staff
• Keep floor plans, access records, utility allocation records, and board approvals
• Review impact on FEZ incentives, cash grants, tax reductions, or employment commitments

The safest rule: document first, move in later.

Practical Example: A Foreign Battery Materials Group

Assume a Singapore parent owns two Korean subsidiaries. Company A is a foreign-invested manufacturer in an FEZ and leases a production facility. Company B is a foreign-invested R&D and sales affiliate that needs laboratory benches, meeting rooms, and warehouse access near Company A’s production line.

Under a more flexible affiliate sharing framework, Company A may be able to let Company B use part of the facility. But the group should still proceed in order:

1. Confirm that Company B’s R&D and sales activities are permitted in the FEZ
2. Check whether the master lease allows affiliate subleasing
3. Obtain authority or landlord consent before Company B moves in
4. Sign a written facility-use agreement with rent, utilities, safety rules, and access rights
5. Update Company B’s business registration if the FEZ site becomes an operating location
6. Allocate shared utilities and equipment costs monthly
7. Keep records in case of tax, immigration, incentive, or bank review

This structure can work well, but only if the legal, real estate, and tax documents tell the same story.

Common Mistakes to Avoid

Foreign companies should avoid these shortcuts:

• Treating affiliate sharing as ordinary coworking space
• Letting an unregistered or non-FDI entity occupy the premises
• Using a facility for a business activity outside the approved FEZ purpose
• Charging related-party rent without VAT invoices or pricing support
• Forgetting to update the affiliate’s business registration address
• Assuming a D-8 visa applicant can rely on shared space without evidence of real operations
• Mixing inventory, employees, or regulated equipment without written responsibility rules
• Ignoring safety, insurance, data security, and access-control issues
