Foreign Investment Tax Credit Application Process: A Complete Step-by-Step Guide
Foreign investment tax credits are available to qualifying foreign-invested companies under Article 121-2 of the Special Tax Treatment Control Act (STTCA), providing exemptions on corporate tax, income tax, acquisition tax, and property tax. Eligibility is limited to companies in high-technology industries or those located within designated foreign investment zones or investment promotion districts, and both the investment scale and industry type must meet the requirements before an application can be submitted. This guide walks through the application process, required documents, and the most common sticking points encountered in practice, step by step.
Basic Structure of the Tax Credit System
National Tax Exemptions and Local Tax Exemptions Follow Different Procedures
Foreign investment tax credits fall into two main categories:
- National taxes (corporate tax and income tax): Governed by Article 121-2 of the Special Tax Treatment Control Act
- Local taxes (acquisition tax and property tax): Governed by Article 78 of the Local Tax Special Treatment Control Act
Both exemptions can be obtained simultaneously, but the application agencies and procedures differ. National tax exemptions must be filed with the competent tax office, while local tax exemptions are applied for at the relevant local government. In practice, it is common for applicants to confuse the two processes and only file one of them.
Exemption Period and Rate Structure
The exemption period and rate vary depending on the industry type and location.
| Category | Initial Exemption Period | Initial Exemption Rate | Additional Exemption After |
|---|---|---|---|
| High-technology industry | 5 years | 100% | 50% for the following 2 years |
| Located in foreign investment zone | 7 years | 100% | 50% for the following 3 years |
| Located in investment promotion district | 5 years | 100% | 50% for the following 2 years |
| Located in free economic zone | 5 years | 100% | 50% for the following 2 years |
Note: The periods and rates above are based on statutory provisions and may vary depending on the specifics of each investment declaration and the decisions of the relevant authority. Always verify directly with the competent authority.
Eligibility Requirements — What Types of Investment Qualify?
High-Technology Industry Designation Is the Key Factor
The most commonly used pathway is the exemption through high-technology industry designation. The business must fall under the "List of High Technologies for Foreign Investment Attraction" published by the Ministry of Trade, Industry and Energy (MOTIE). Simple manufacturing, distribution, and general service businesses are generally not eligible.
The most common practical sticking point is industry code classification. The industry code registered at the time of company incorporation must exactly match the high-technology list for the review to pass. Even closely related codes will be grounds for denial if they do not match precisely.
Practical tip: Before incorporating, compare your business activities against the high-technology list. Changing the industry code after incorporation involves additional procedures and costs.
Foreign Investment Declaration Is a Prerequisite
To qualify for tax exemptions, the foreign investment declaration under Article 5 of the Foreign Investment Promotion Act must first be completed. If the declaration is not filed with a foreign exchange bank or KOTRA before the investment is made, tax exemption applications submitted afterward will not be accepted. This is where problems often begin — when investors execute the investment first and attempt to file the declaration retroactively, they may forfeit their eligibility for exemptions entirely.
Minimum Investment Amount Requirements
Tax exemption applications are subject to minimum investment amount thresholds, which vary by industry and location. These thresholds are subject to change based on government notices.
Note: Minimum investment amount thresholds have been subject to recent revisions. Consult with the relevant authority to confirm whether your current investment level meets the threshold.
Foreign Investment Tax Credit Application Process — A 4-Step Flow
Step 1: Pre-Review of Eligible Industry Type
Before filing an exemption application, the first step is to confirm whether your investment falls within an eligible industry. You can review Article 121-2 of the Special Tax Treatment Control Act and its enforcement decree annexes directly on the National Law Information Center. Whether your business qualifies as a high-technology industry can be confirmed through a pre-inquiry with the Ministry of Trade, Industry and Energy or the KOTRA Foreign Investment Support Center.
This is typically where applicants get stuck — many attempt to determine eligibility on their own and end up proceeding based on incorrect information.
Step 2: Foreign Investment Declaration and Company Registration
Submit a foreign investment declaration form to a foreign exchange bank or KOTRA. Upon completion, the company will be registered as a foreign-invested enterprise, and the registration number issued will serve as the reference for all subsequent exemption applications. If the declaration date is later than the actual date of investment, issues may arise with exemption eligibility.
Step 3: Submitting the Exemption Application — Agency and Deadline
| Exemption Type | Application Agency | Application Deadline |
|---|---|---|
| Corporate/income tax exemption | Competent tax office | Within 3 months after the end of the fiscal year |
| Acquisition tax exemption | Relevant local government | Within 60 days from the date of acquisition |
| Property tax exemption | Relevant local government | Prior to the tax base date |
Missing a deadline means the exemption for that year cannot be applied retroactively. The 60-day acquisition tax deadline in particular is short, making it essential to begin the application process immediately after incorporation.
Step 4: Exemption Decision and Application
After reviewing the application, the competent authority will notify the applicant of the exemption decision. Corporate tax exemptions are applied by directly deducting the exempted amount from the tax liability at the time of filing. Acquisition and property tax exemptions are reflected on the tax notice after the local government issues its decision.

List of Documents Required for Application
Documents for Corporate Tax Exemption Application
In actual reviews, examiners focus on the consistency of the content rather than the volume of documents. In particular, the alignment between the investment payment process and the contents of the business plan is a key area of scrutiny.
- Foreign investment exemption application form (National Tax Service form)
- Copy of the foreign investment declaration
- Copy of the foreign-invested enterprise registration certificate
- Copy of the articles of incorporation
- Copy of the business registration certificate
- High-technology confirmation certificate (issued by the Ministry of Trade, Industry and Energy — required where applicable)
- Investment payment documentation (foreign wire transfer confirmation, paid-in capital verification, etc.)
- Business plan (if requested by the competent tax office)
Documents for Local Tax Exemption Application
Required documents may differ by local government. Be sure to confirm the document list with the relevant agency before visiting.
- Foreign investment local tax exemption application form (each local government's own form)
- Copy of the foreign-invested enterprise registration certificate
- Copy of the foreign investment declaration
- Acquisition-related documents (in the case of real estate, machinery, or other acquisitions)
Practical tip: Local government staff may not always be familiar with foreign investment exemption procedures. Confirming the responsible department and contact person in advance can significantly reduce processing time.
Common Practical Sticking Points
Delays in Obtaining the High-Technology Confirmation Certificate
The high-technology confirmation certificate is issued by the Ministry of Trade, Industry and Energy, and processing can take several weeks or more. To meet the corporate tax filing deadline, the application for this certificate should be initiated at least two to three months in advance. Applying without the certificate will result in the exemption decision being put on hold or denied outright.
Difficulty Connecting Investment Payment Documentation
Simply having a foreign wire transfer deposited into a bank account is not sufficient. A separate written confirmation from a foreign exchange bank is required to verify that the purpose of the transfer was "paid-in capital." In recent cases, transfers that passed through a personal domestic bank account before reaching the corporate account resulted in a broken chain of documentation, causing exemption applications to be denied. If the flow of funds cannot be clearly traced, complications arise quickly.
Interpreting the Business Commencement Date
The "business commencement date," which marks the starting point for the exemption period, may differ from the date of incorporation. It is determined based on when actual business activities began and is separately verified by the tax office. If this date is not clearly established, the applicable exemption period may be reduced.
Note: The determination of the business commencement date varies by case, and the competent tax office's interpretation is the standard. Confirm the applicable start date with a professional before proceeding.
Post-Exemption Management — Clawback Risk
Obligations to Maintain During the Exemption Period
Even after exemptions begin, the following obligations must be maintained:
- Maintaining registered status as a foreign-invested enterprise
- Fulfilling the business plan submitted at the time of the exemption application
- Maintaining the required headcount if employment conditions apply
- Submitting annual performance reports (required in some regions)
Circumstances Under Which an Exemption May Be Revoked
In the following circumstances, exemptions may be revoked and previously exempted taxes may be clawed back:
- Operating a business outside the designated eligible industry
- Withdrawing the investment or transferring equity interests
- Filing for exemption using fraudulent documents
- Failing to meet employment maintenance requirements
If a clawback occurs, the company must pay the exempted taxes plus additional penalties. If any changes to the business structure, equity holdings, or industry type occur during the exemption period, always confirm with the competent authority before making the change.
Practical tip: If corporate structure changes or equity transfers occur during the exemption period, check with the competent authority immediately. If discovered after the fact, this will result in a clawback including penalties.
Frequently Asked Questions
Q. Can all foreign-invested companies receive foreign investment tax credits?
No. Applications are only available to companies that meet the statutory criteria — specifically those in high-technology industries or located within foreign investment zones, investment promotion districts, or free economic zones. Simple investments or companies operating in general industries are not eligible.
Q. How many years after incorporation can I apply for a tax exemption?
Exemption applications must be filed within the corporate tax filing deadline for each fiscal year. If you miss the application for a given year, the exemption for that year cannot be applied retroactively. Missing the first-year application is one of the most common oversights in practice.
Q. Where do I obtain the high-technology confirmation certificate?
Apply through the Ministry of Trade, Industry and Energy or KOTRA. Since the process takes several weeks, you need to apply well in advance, working backward from your corporate tax filing deadline.
Q. Can I receive exemptions if my company is not located in a designated foreign investment zone?
If your business is confirmed as a high-technology industry, exemptions are available regardless of location. Location-based exemptions apply only if your business premises are within the designated area. If you qualify under both criteria, you can choose whichever option is more advantageous.
Q. I missed the 60-day acquisition tax exemption application deadline. What should I do?
Whether a late application is possible depends on the relevant local government and the specifics of the case. If the deadline has passed, the best course of action is to contact the competent authority as quickly as possible to identify your options.
Q. Can I receive both a foreign investment tax exemption and an R&D tax credit simultaneously?
In principle, overlapping applications for the same investment are restricted. Depending on the nature of the investment and the applicable provisions, certain combinations may be permissible, but this is a complex area of tax law interpretation. The applicability must be carefully reviewed on a case-by-case basis before proceeding.
