Merger vs Amalgamation in Thailand: 2023 CCC Amendment Explained

TL;DR: Before February 2023, Thai limited companies wishing to combine could only 'amalgamate' — both companies dissolved into a new entity. The Civil and Commercial Code Amendment Act (No. 23) B.E. 2566 introduced 'merger' (การควบรวม) — one company survives, the other dissolves into it. Merger is faster, preserves contracts and licenses of the surviving entity, and is generally tax-neutral, but the procedure still requires shareholder approvals, creditor notice, and Department of Business Development registration.

The Pre-2023 Position: Amalgamation Only

Under the original Civil and Commercial Code provisions on company combinations (Sections 1238-1242), the only mechanism for combining two or more limited companies was amalgamation (การควบกิจการ). Both/all companies dissolved, and a new amalgamated entity took over their assets, liabilities, rights, and obligations. While this preserved the underlying business in legal form, it created practical difficulties:

• All contracts had to be reissued or formally assigned to the new entity
• Government licenses and BOI promotions had to be reapplied for or transferred
• Banking arrangements, leases, and IP registrations needed updating
• Trade name and goodwill associated with the dissolved companies needed special preservation steps

The 2023 Amendment

The Civil and Commercial Code Amendment Act (No. 23) B.E. 2566, published in the Royal Gazette on 8 November 2022 and effective 7 February 2023, introduced merger as a separate, distinct mechanism. The relevant amended provisions are in the section governing amalgamation (now combined provisions for both forms in Sections 1238 onward, with 1238/1, 1238/2, etc. for merger-specific rules).

Merger vs Amalgamation: Key Differences

Feature	Amalgamation (การควบกิจการ)	Merger (การควบรวม)
Legal continuity	All companies dissolved; new entity formed	One company survives; other(s) dissolved into it
Contracts	Transfer to new entity by operation of law (still requires due diligence)	Continue uninterrupted with surviving entity
Licenses/permits	Generally need transfer or reapplication	Generally retained by surviving entity
Goodwill / trade name	Must be transferred or merged into new entity's identity	Surviving entity retains its identity
Tax implications	Tax-neutral if statutory conditions met (Revenue Code Section 73)	Tax-neutral if statutory conditions met
Use case	Combining equally-sized entities, rebranding	Acquiring a target into an existing parent

The Merger Procedure

Combining two or more limited companies via merger requires:

1. Board approval at each company, recommending the merger to shareholders.
2. Special shareholder resolution at each company — three-quarters majority of shares present and voting, under Section 1194 of the Civil and Commercial Code.
3. Creditor notice and objection period — notice published and sent to known creditors. Creditors have 60 days to object. Objections must be resolved (paid, secured, or contested) before registration can proceed.
4. Merger agreement — formal agreement between merging companies setting out terms, share exchange ratio (if applicable), surviving entity, dissolution arrangements.
5. Registration with the Department of Business Development (กรมพัฒนาธุรกิจการค้า, DBD) — filings include the merger agreement, special resolutions, creditor notice evidence, updated articles of the surviving entity, and lists of new shareholders/directors.
6. Tax filings — final tax returns for the dissolving entity, transfer of tax registrations, BOI notifications if applicable.

Tax Implications

Both merger and amalgamation can be structured to be tax-neutral under the Revenue Code, provided statutory conditions are met. Key provisions include Section 73 (treating qualifying combinations as not creating taxable disposal events) and Royal Decree provisions on entire-business-transfers. Critical conditions:

• The combination must be of complete businesses, not selective asset transfers
• Tax loss carryforwards and accumulated depreciation generally do not transfer (specific exemptions apply)
• VAT registration must be updated; final VAT returns filed
• Specific Business Tax considerations for real-estate-holding companies

BOI and Licensed Activities

BOI promoted companies require Board of Investment notification and approval for both merger and amalgamation. The BOI generally permits combinations and transfers of promotion certificates, but case-by-case review is required, particularly where activities or shareholding ratios change. Foreign-licensed activities under the Foreign Business Act B.E. 2542 (1999) similarly require notification to the DBD's Foreign Business Commission.

Cross-Border Considerations

Thai law does not currently permit direct merger between a Thai company and a foreign company. International combinations typically structure through:

• Domestic merger of a Thai subsidiary into a Thai acquiring entity
• Asset purchase from a Thai company by a foreign-controlled vehicle
• Share acquisition (subject to Foreign Business Act and BOI implications)

Common Mistakes

Common Mistakes: (1) Failing to publish creditor notice properly — creditor objection periods are strict, and missed notice can void the merger registration. (2) Assuming all licenses transfer automatically — many sector-specific licenses (alcohol, tobacco, telecommunications, financial services) require pre-approval from the relevant regulator. (3) Mishandling employee notifications — though employment contracts continue with the surviving entity, Section 13 of the Labour Protection Act B.E. 2541 (1998) requires notification and the new employer must accept all existing terms. (4) Overlooking the Revenue Code conditions for tax-neutrality — minor procedural defects can trigger taxable disposal treatment.

FAQs

Can a Thai limited company merge with a Thai public limited company?

The 2023 amendment governs limited companies under the Civil and Commercial Code. Public limited companies are governed by the Public Limited Companies Act B.E. 2535 (1992), which has its own merger and amalgamation provisions. Cross-form combinations are possible but require careful structuring, often through preliminary conversion of one entity to match the other's form.

How long does a merger take in practice?

From shareholder resolutions to DBD registration, typically 3-6 months in straightforward cases. Creditor objection periods and regulatory approvals can extend this. Complex BOI-promoted businesses with cross-border elements may take 9-12 months.

Can a sole shareholder use the merger procedure?

Yes. With the 2023 amendment also reducing the minimum shareholder requirement from 3 to 2, single-shareholder combinations between affiliated entities are now common in group restructuring.

Does merger require a fairness opinion?

For private limited companies, Thai law does not mandate an independent fairness opinion. However, where minority shareholders exist, a fair share-exchange ratio is essential to avoid challenges under Section 1194 (special resolution challenge) and Section 1175 (oppression-style remedies).

What happens to litigation in progress?

The surviving entity (in a merger) or new entity (in an amalgamation) succeeds to all rights and liabilities, including pending litigation. The court will substitute the successor entity as a party. Pre-existing judgments are enforceable against the successor.
