Vietnam Investment Registration Certificate (IRC): A Complete Guide for Foreign Investors (2026)

Introduction

For any foreign investor seeking to establish a business presence in Vietnam, the Investment Registration Certificate (IRC) is the foundational legal document. It is the government's formal approval of your investment project — and without it, most foreign-invested enterprises (FIEs) cannot legally operate.

Vietnam remains one of Southeast Asia's most attractive destinations for foreign direct investment. The country recorded FDI disbursement of approximately USD 25.35 billion in 2024, up 9.4% year-on-year (Source: Ministry of Planning and Investment of Vietnam, 2025). Manufacturing, real estate, and technology sectors continue to attract the largest inflows. Yet despite this momentum, the regulatory entry process has historically been one of the most complex in the region.

That changed significantly on 1 March 2026, when Vietnam's Law on Investment 2025 — approved by the National Assembly on 11 December 2025 — came into effect. The new law introduces the most substantial reform to Vietnam's foreign investment entry framework in over a decade. Understanding what has changed, and what has not, is essential for any investor entering the market in 2026.

This guide explains what the IRC is, when it is required, how to apply, what documents you need, realistic timelines, and the key 2026 regulatory changes that affect your entry strategy.

What Is the Investment Registration Certificate (IRC)?

The Investment Registration Certificate is an official document issued by Vietnam's Department of Planning and Investment (DPI) — or, in the case of projects located within industrial zones, export processing zones, or economic zones, by the relevant zone management board.

The IRC formally approves a foreign investor's investment project in Vietnam. It is distinct from the Enterprise Registration Certificate (ERC), which establishes the legal entity (the company itself). The IRC approves what the company is permitted to do and invest in; the ERC creates the legal vehicle through which it does so.

A standard IRC contains the following information:

It is important to understand that the IRC does not create a legal entity. After receiving the IRC, investors must separately obtain the ERC to incorporate the company.

When Is an IRC Required?

Under the Law on Investment 2020 (and continuing under the Law on Investment 2025), an IRC is generally required in the following circumstances.

A foreign investor establishes a new company in Vietnam with any level of foreign ownership. A foreign investor acquires shares or capital contributions in a Vietnamese company in a conditional business sector, or where the acquisition results in foreign ownership exceeding 50%. An existing foreign-invested enterprise expands its investment project by adding new business lines, increasing capital, or changing its project location. The investment project is located within an industrial zone, export processing zone, high-tech zone, or economic zone.

An IRC is generally not required when a Vietnamese company with no foreign ownership is established, or when a foreign investor acquires a minority stake in a non-conditional sector below the regulatory ownership threshold.

However, sector-specific licensing requirements may apply regardless of the IRC requirement. Investors in conditional business lines — such as financial services, education, healthcare, logistics, and certain technology sectors — must obtain additional licences or meet minimum capital requirements beyond the IRC.

The 2026 Reform: What Has Changed Under the Law on Investment 2025

The most significant change introduced by the Law on Investment 2025 (effective 1 March 2026) reverses decades of established practice: foreign investors can now establish a legal entity and obtain an Enterprise Registration Certificate (ERC) before securing an Investment Registration Certificate (IRC) (Source: Tractus Asia, February 2026).

Under the previous framework, investors were required to obtain IRC approval before they could incorporate. This meant that a company could not open a bank account, sign an office lease in its own name, hire employees, or begin any operational activity until the investment project had been approved — a process that could take 30 to 60 working days or more in complex sectors.

Under the new ERC-first sequence, manufacturers and service companies can now set up their legal entity, open bank accounts, sign office leases, hire local design and engineering firms, begin staff recruitment, and conduct market validation while IRC approval is still pending.

Additional reforms introduced by the Law on Investment 2025 include the following. The number of conditional business lines has been reduced from 236 to 198, removing licensing requirements for 38 sectors including tax advisory services, customs brokerage, and certain transport and construction activities (Source: Tractus Asia, February 2026). Investment policy approval is now limited to approximately 20 project types, including nuclear energy, casinos, telecommunications infrastructure, and projects requiring large-scale land use. Projects in industrial parks, export processing zones, high-tech zones, and economic zones can use fast-track procedures. Provincial People's Committee Chairs now approve most projects, decentralising decision-making and potentially accelerating timelines.

The IRC Application Process: Step-by-Step (2026)

Step 1: Determine Whether an IRC Is Required

Before preparing any documentation, confirm whether your investment structure and sector require an IRC. Investors in non-conditional sectors acquiring minority stakes in Vietnamese companies may not need one. Investors establishing a new FIE almost always will.

Step 2: Prepare the Investment Project Documentation

The standard IRC application dossier, as specified under the Law on Investment 2020 (Article 36) and confirmed under the 2025 amendments, includes the following.

For individual foreign investors: a notarised and consular-legalised copy of a valid passport; a bank statement or financial institution confirmation demonstrating sufficient capital to fund the project; an investment project proposal describing objectives, location, scale, capital, implementation schedule, and expected outcomes; an office or factory lease agreement for the registered business address; and a proposed company charter.

For corporate foreign investors: a notarised and consular-legalised copy of the Business Registration Certificate (or equivalent) of the investing entity; audited financial statements for the most recent two years, or a financial commitment letter from the parent company; an investment project proposal; an office or factory lease agreement; a proposed company charter; and a resolution or decision of the board of directors authorising the investment.

All foreign-language documents must be notarised in the country of origin, consular-legalised (apostilled where applicable), and accompanied by a certified Vietnamese translation (Source: Dedica Law, October 2025).

Step 3: Submit the Application to the DPI or Zone Authority

The completed dossier is submitted to the provincial Department of Planning and Investment where the project will be located, or to the industrial zone management board if the project is within a designated zone.

The reviewing authority will assess whether the proposed business activities are permitted under Vietnam's WTO commitments and sector-specific regulations, whether the investment capital is adequate for the proposed project scope, whether the registered address complies with zoning regulations, and whether the investor has demonstrated financial capacity.

Step 4: Government Review and Clarification

The DPI may request additional documents, seek clarification on business activities or capital structure, or consult with other ministries for projects in regulated sectors. In conditional sectors, inter-ministerial consultation is common and adds time to the process.

Step 5: Issuance of the IRC and Post-Licensing Steps

If the application is approved, the DPI issues the Investment Registration Certificate. The investor then proceeds to apply for the Enterprise Registration Certificate (ERC) at the Business Registration Office (typically 3 to 5 working days); open a direct investment capital account (DICA) at a licensed bank in Vietnam; contribute charter capital within 90 days of ERC issuance (per Article 75 of the Law on Enterprises 2020); register for taxes and obtain a tax identification number; apply for any sector-specific licences required for the approved business activities; and register the company seal and enrol employees in social insurance.

Document Checklist

Timelines

The statutory processing time for an IRC is 15 working days from the date of submission of a complete and valid dossier, as specified under the Law on Investment 2020 (Article 38) and maintained under the 2025 amendments (Source: Viet An Law, 2026).

In practice, timelines vary considerably:

The ERC, once the IRC is obtained, is typically issued within 3 to 5 working days. Capital contribution must be completed within 90 days of ERC issuance.

Common Reasons for Rejection or Delay

Understanding the most frequent causes of IRC rejection can significantly reduce delays and avoid costly resubmissions.

Vague or overly broad business scope. Vietnam requires precise business line descriptions using the Vietnam Standard Industrial Classification (VSIC) system. Generic descriptions such as "consulting services" or "trading" without further specification frequently trigger clarification requests or outright rejection (Source: GTI Partner, February 2026).

Insufficient financial evidence. The DPI must be satisfied that the investor has the financial capacity to fund the proposed project. Weak bank statements, inconsistent capital figures, or a mismatch between proposed investment scale and demonstrated financial capacity are common rejection triggers.

Restricted or conditional sector misclassification. Certain industries require minimum capital thresholds, mandatory local partner arrangements, or additional ministerial approvals. Failure to identify and address these requirements at the application stage is a frequent and avoidable error.

Non-compliant registered address. The business address must be zoned for commercial use, have valid landlord documentation, and comply with fire safety and building regulations. Residential apartments are not permitted as registered business addresses for FIEs.

Incomplete legalisation of foreign documents. Documents must be notarised in the country of origin, consular-legalised, and accompanied by a certified Vietnamese translation. Any deficiency in the legalisation chain invalidates the document and the application.

IRC vs ERC: Understanding the Difference

A common source of confusion for first-time investors in Vietnam is the distinction between the IRC and the ERC.

Under the Law on Investment 2025 (effective 1 March 2026), the ERC can now be obtained before the IRC in most cases — a significant departure from the previous IRC-first sequence. For a detailed walkthrough of the ERC process and foreign ownership rules, see our guide on Can Foreigners Own a Company in Vietnam?.

Strategic Considerations

The IRC is not merely a regulatory formality. The decisions made at the IRC stage — the approved business lines, the registered capital amount, the project location, and the operating term — define the operational and legal boundaries of your company for years to come.

Incorrect structuring at the IRC stage can limit your ability to add business lines later, require costly amendments, or in some cases necessitate a full restructuring of the investment. Investors who treat the IRC as an administrative checkbox rather than a strategic document frequently encounter these constraints as their business evolves.

Key strategic decisions to resolve before filing include: the optimal legal entity structure (limited liability company vs joint-stock company); the appropriate level of registered capital relative to your operational plans; whether to locate within an industrial zone (which provides fast-track procedures and tax incentives) or in a standalone commercial location; and whether your business activities fall within conditional sectors requiring additional licences.

Conclusion

Vietnam's Investment Registration Certificate remains the gateway to legal foreign investment in the country. The Law on Investment 2025, effective 1 March 2026, has made the entry process more flexible — allowing company formation before project approval, reducing conditional business lines, and decentralising approval authority — but has not reduced the importance of getting the IRC right.

A well-prepared IRC application, with precise business scope, adequate financial evidence, and a compliant registered address, will move through the DPI in 20 to 30 working days. A poorly prepared one can take months and result in a structurally constrained company that is difficult to expand later.

Foreign investors entering Vietnam in 2026 should approach the IRC process as a strategic exercise, not an administrative one.
