How the M&A Approval Process Works in Taiwan: Step‑by‑step Guide for Buyers & Sellers

The M&A approval process in Taiwan requires buyers and sellers to navigate a layered regulatory framework involving the Ministry of Economic Affairs (MOEA), the Financial Supervisory Commission (FSC), the Taiwan Stock Exchange (TWSE), and, where competition thresholds are met, the Fair Trade Commission (FTC). Whether the transaction is a statutory merger, a share acquisition exceeding disclosure thresholds, or an inbound cross‑border investment, each deal must pass through a defined sequence of corporate approvals, government filings, and post‑closing registrations. This guide sets out the full procedure, eligibility checks, required documents, realistic timelines, costs, and the tighter screening measures that have taken effect in 2026, so that corporate counsel, foreign investors, and deal teams can plan each stage with confidence.

Overview of the M&A Approval Process and Who It Applies To

Taiwan’s principal M&A statute is the Business Mergers and Acquisitions Act (the “M&A Act”), which sits alongside the Company Act, the Securities and Exchange Act, and sector‑specific investment regulations. Together, these laws govern statutory mergers, consolidations, share exchanges, and asset or share acquisitions that cross regulatory thresholds.

The regulatory approvals required for M&A transactions in Taiwan depend on four variables: (1) whether the target is a publicly listed or private company; (2) whether the buyer is a domestic entity, a foreign investor, or a PRC‑related party; (3) whether the target operates in a restricted sector listed on the government’s negative list; and (4) whether the transaction triggers mandatory tender offer obligations or FTC merger‑control filing thresholds.

For public targets, the FSC and TWSE impose real‑time disclosure obligations and mandatory tender offer rules under the Securities and Exchange Act. For private targets, the process centres on MOEA filings (particularly for foreign investment) and internal corporate approvals under the Company Act and the M&A Act. Transactions involving both public and private elements, such as a foreign buyer acquiring a controlling stake in a listed Taiwanese company, may require concurrent filings with MOEA, FSC, TWSE, and potentially the FTC.

Eligibility and Prerequisites for the M&A Approval Process in Taiwan

Public vs private targets, different approval paths

When the target is a public company (listed on the TWSE or Taipei Exchange/TPEx), the acquisition of shares above prescribed thresholds triggers immediate disclosure duties and, in certain cases, a mandatory tender offer. The board of the target must also evaluate whether the transaction constitutes a material event requiring a public announcement under TWSE listing rules.

For a private company, no securities disclosure obligations apply. The M&A Act permits a “short‑form” merger without a full shareholder vote where a parent company holds 90 per cent or more of the shares in a subsidiary, in that case, board approval alone suffices (M&A Act). For all other private‑company mergers, a special shareholder resolution is required.

Foreign investor screening and restricted sectors

Foreign investors, including entities with PRC‑connected beneficial ownership, must obtain foreign investment approval from MOEA before completing an acquisition. MOEA maintains a “negative list” of industries in which foreign investment is prohibited or restricted (covering sectors such as certain utilities, telecommunications, and defence). Where the proposed investment falls within a restricted sector or raises national security concerns, the review period is extended and may involve inter‑agency consultation.

Securities thresholds and mandatory tender offer triggers

Under the Securities and Exchange Act, any person who acquires, individually or together with related parties, more than a prescribed percentage of a listed company’s outstanding shares within a defined period must launch a mandatory tender offer in Taiwan. The FSC sets the precise thresholds and calculation methodology, which take into account direct purchases, concert‑party holdings, and creeping acquisitions. Buyers must calculate their aggregate holdings before each incremental acquisition to determine whether a tender offer obligation has been triggered. Failure to comply can result in the transaction being voided and administrative penalties.

Step‑by‑Step M&A Approval Procedure

The following table summarises each major step in the M&A approval process in Taiwan, who is responsible, and the typical duration. Expanded guidance for each step follows the table.

Step 1. Pre‑deal planning and strategy

The deal team determines the transaction structure, share acquisition, asset purchase, or statutory merger, and maps every regulatory gate the deal must pass. At this stage, counsel should check the MOEA negative list for sector restrictions, assess whether the buyer’s ownership chain includes PRC‑related entities, identify potential FTC merger‑control filing obligations, and flag any national‑security sensitivities. Choosing between a share deal and an asset deal has significant implications for tax, employee‑transfer obligations under the M&A Act, and the number of regulatory filings required.

Step 2. NDA, initial information exchange and preliminary due diligence

Both parties execute a non‑disclosure agreement. The buyer conducts preliminary due diligence covering the target’s corporate records, financial statements, material contracts, intellectual property, and regulatory licences. The preliminary findings inform valuation and the conditions precedent that will appear in the letter of intent. Where the target is a listed company, information barriers must comply with insider‑trading restrictions under the Securities and Exchange Act.

Step 3. Letter of intent (LOI) or Heads of Terms

The LOI records the agreed deal structure, indicative price, and, critically, the schedule of regulatory approvals that constitute conditions precedent. It should list each filing (MOEA foreign investment approval, FTC merger notification, shareholder vote) and the estimated processing time for each, giving the parties a realistic closing date.

Step 4. Submit foreign investment filing to MOEA

If the buyer is a foreign entity or the investment involves a restricted sector, the buyer, usually through local counsel, submits a foreign investment application to MOEA. The filing requires an investment plan, source‑of‑funds disclosure, beneficial‑ownership details, and certified corporate documents (see the Required Documents table below). MOEA’s typical processing time is 30–60 calendar days; where the application triggers a national‑security review or involves PRC‑related investors, processing may extend to 90 days or longer.

Step 5. Securities disclosures and mandatory tender offer calculations

For listed targets, the buyer must file immediate disclosure announcements with the TWSE or TPEx once the transaction meets material‑event thresholds. Separately, the buyer must calculate whether its aggregate shareholding, including shares held by related parties, triggers a mandatory tender offer under the Securities and Exchange Act. The calculation includes directly purchased shares, shares held through nominees, and any concert‑party arrangements. If the threshold is breached, the buyer must launch a public tender offer in accordance with FSC rules before completing the acquisition.

Step 6. Confirmatory due diligence and regulatory Q&A

While regulatory filings are processed, the buyer conducts confirmatory due diligence, verifying representations, reviewing tax exposures, assessing employment liabilities, and checking environmental compliance. In parallel, deal counsel responds to questions from MOEA, FSC, or FTC examiners. Prompt, well‑prepared responses prevent delays; incomplete answers can add weeks to the review cycle.

Step 7. Board and shareholder approvals

Both the buyer’s and the target’s boards must formally resolve to approve the transaction. For a statutory merger under the M&A Act, each participating company must also obtain shareholder approval by special resolution, requiring the presence of shareholders representing at least two‑thirds of total issued shares (or such other quorum as the articles prescribe) and the affirmative vote of the majority of shares present. Under the Company Act, notice for a regular shareholders’ meeting must be dispatched at least 30 days before the meeting. For special meetings, shorter notice periods apply (typically 15–30 days, depending on the company’s articles). Foreign signatories may need notarised and legalised powers of attorney; Chinese‑language translations of all resolutions must be prepared for regulatory filings.

Step 8. Regulatory decision and clearance

Regulatory agencies issue their decisions. MOEA grants (or conditions) the foreign investment approval; the FSC confirms compliance with securities rules; and, where applicable, the FTC clears the merger after reviewing market‑concentration data. Processing times range from 30 to 90 calendar days depending on the agency, transaction complexity, and whether a Phase II review is required under FTC merger‑control rules. Clearance may be conditional, common conditions include divestitures, employment‑retention undertakings, or periodic reporting obligations.

Step 9. Signing and closing

Once all conditions precedent are satisfied, the parties execute the definitive agreements and deliver consideration. For share acquisitions of listed companies, share transfers are processed through the Taiwan Depository & Clearing Corporation (TDCC) on a T+2 settlement basis. For private companies, the buyer’s name is entered in the share register and a revised shareholders’ list is filed with the Company Registrar.

Step 10. Post‑closing filings, settlement and integration

Post‑closing filings must be made with MOEA (updated company registration), the FSC and TWSE (if the target remains listed), and the local tax authority (stamp duty, securities transaction tax). The buyer should update the target’s share register, file any required beneficial‑ownership disclosures, and retain all transaction records for the statutory retention period. Industry observers expect regulators to increase post‑closing audit activity in 2026, particularly for deals involving foreign or PRC‑related buyers.

Documents Needed for M&A in Taiwan

The table below consolidates the core documents needed for M&A in Taiwan. Actual requirements vary by transaction type, target status (listed or private), and whether the buyer is foreign. All foreign‑language documents must be accompanied by certified Chinese translations for regulatory filings.

For foreign buyers, the most common source of delay is the legalisation of corporate documents. Apostille or consular legalisation can take 2–4 weeks depending on the issuing jurisdiction. Deal teams should begin the legalisation process as soon as the transaction structure is agreed, ideally before the LOI is signed.

M&A Timeline in Taiwan: Key Deadlines and Durations

Transaction timelines vary significantly by deal complexity, but the table below provides a practical reference for scheduling each milestone in the M&A approval process in Taiwan.

A straightforward domestic acquisition of a private company with no foreign‑investment or competition‑filing requirements can close in as few as 8–12 weeks from LOI. Cross‑border deals involving MOEA foreign investment approval and FTC merger control review routinely take 4–6 months. Deals raising national‑security concerns or touching restricted sectors may extend to 9 months or longer once the 2026 screening intensification is factored in.

The Company Act’s 30‑day notice period for regular shareholders’ meetings is the most commonly underestimated scheduling constraint. Deal teams should work backward from the target closing date: identify the latest possible shareholders’ meeting date, subtract 30 days for notice, and add time for document preparation and board pre‑approval.

Costs, Fees, and Tax Considerations

The following cost table provides guidance‑level estimates. All figures should be confirmed directly with the relevant regulator or professional adviser before reliance.

Stamp duty on share transfer documents and the securities transaction tax on listed‑share sales are the two most commonly overlooked transactional taxes. Both must be settled before post‑closing filings can be completed.

What Changes in 2026: Tighter Screening and Longer Review Periods

Throughout 2025 and into 2026, Taiwan’s regulators have intensified scrutiny of foreign and PRC‑related investments. The likely practical effect of this trend is threefold. First, MOEA is applying national‑security reviews more frequently, particularly for acquisitions in semiconductors, critical infrastructure, and supply‑chain‑sensitive industries. Second, inter‑agency coordination between MOEA, the FSC, and the FTC has accelerated, meaning that deficiencies identified by one agency are shared with others, increasing the importance of consistent, thorough filings. Third, early indications suggest that review periods for sensitive transactions have extended by 30–60 calendar days compared with pre‑2025 norms.

Buyers planning a cross‑border acquisition should build an additional 30–60 day buffer into their deal timeline, prepare enhanced national‑security and supply‑chain disclosures at the outset, and engage Taiwan‑qualified counsel before executing the LOI.

Common Pitfalls in the M&A Approval Process and How to Avoid Them

• Missed mandatory tender offer threshold. Failing to aggregate concert‑party holdings when calculating shareholding percentages can trigger an undisclosed breach. Run the calculation before every incremental acquisition.
• Inadequate shareholder meeting notice. Dispatching notice fewer than 30 days before a regular meeting invalidates the resolution. Calendar the notice date from day one.
• Unlegalised foreign documents. Submitting corporate documents without apostille or consular legalisation causes automatic rejection by MOEA. Start legalisation 4–6 weeks before the filing date.
• Underestimating FTC review scope. Parties often assume the competition filing is a formality; a Phase II review can add 60+ days. Prepare a robust economics report at the initial filing stage.
• Insufficient employee consultation. The M&A Act requires notification to, and in some cases negotiation with, employees affected by a merger. Omitting this step can delay regulatory clearance and expose the buyer to claims.
• Incomplete beneficial‑ownership disclosure. AML regulations require full disclosure of ultimate beneficial owners. Partial disclosure triggers supplementary information requests and extends MOEA processing.
• Tax / corporate structure misalignment. Choosing a share deal over an asset deal (or vice versa) without modelling the stamp duty, securities transaction tax, and capital gains consequences can result in material unexpected costs at closing.
• Ignoring post‑closing filing deadlines. Late filings with MOEA, the Company Registrar, or the tax authority attract penalties and may jeopardise the validity of the registration. Assign a compliance officer to track every post‑closing deadline.
