How to Choose an M&A Lawyer in Taiwan: 8 Questions to Ask and What It Should Cost (2026)

Key Takeaways

• — Approval is a gate, not a formality. Acquiring a Taiwanese company requires prior approval from the Department of Investment Review (DIR); sector restrictions and PRC-connection look-through can decide whether the deal is permitted at all.
• — TFTC merger thresholds were raised in January 2026: filing is required at combined global turnover above NT$50 billion with two parties each at NT$3 billion+ in Taiwan; or NT$20 billion/NT$3 billion (non-financial) and NT$40 billion/NT$3 billion (financial) single-party tests.
• — Ask eight questions before engaging counsel — a written approval map, sector-specific DIR track record, ownership-chain testing methodology, diligence staffing and languages, and integrated structure-plus-tax advice.
• — Fees correlate with regulatory tracks, not deal size. Taipei commercial rates commonly run NT$7,000–12,000 per hour; fixed fees by workstream give mid-market buyers better budget certainty.
• — Timeline: 8–12 weeks for a domestic private deal; 4–6 months for a cross-border acquisition with DIR approval and a TFTC filing; 9 months or longer in sensitive sectors.

If you are acquiring a Taiwanese company, the lawyer you engage in the first two weeks will shape the economics of the entire transaction. Not because M&A counsel in Taiwan are unusually good or unusually expensive, but because Taiwan’s approval architecture is front-loaded. Structuring decisions that look purely commercial — where the acquiring vehicle sits, whether you buy shares or assets, how much of the target you take in a first tranche — determine which regulators you face, how long you wait, and in several cases whether the deal is permitted at all. By the time most buyers instruct counsel, some of those decisions have already been made.

This guide sets out the eight questions that reliably distinguish counsel who have actually closed inbound deals in Taiwan from counsel who will learn on your transaction. It then explains how Taiwanese M&A fees are structured and what drives the number, so you can read a fee proposal properly rather than comparing headline rates.

Why Selecting M&A Counsel in Taiwan Is Not a Generic Exercise

Three features of the Taiwanese market make counsel selection consequential in ways it is not in, say, Singapore or the Netherlands.

Approval is a gate, not a formality. Foreign investment into Taiwan requires prior approval from the Department of Investment Review (DIR) at the Ministry of Economic Affairs — the body that succeeded the former Investment Commission after the ministry’s 2023 restructuring. This is not a notification. Certain sectors sit on a negative list under the Statute for Investment by Foreign Nationals, where foreign shareholding is capped or prohibited outright. Others — semiconductors, telecommunications, critical infrastructure, defence-adjacent manufacturing — attract heightened national security scrutiny even where they are nominally open.

Capital origin is scrutinised through the chain, not at the surface. Taiwan operates a dual-track review that treats investors with mainland Chinese connections under a materially stricter regime. Crucially, the analysis looks through your holding structure. A German or Dutch acquiring entity with a mainland Chinese limited partner in a fund several layers up can be classified as a PRC investor, with consequences ranging from extended review to outright prohibition. Counsel who do not raise this in the first meeting are not counsel you want.

The target usually is not confined to Taiwan. Taiwanese mid-market companies of the kind foreign buyers actually acquire — precision components, electronics assembly, industrial materials, consumer brands — very often run manufacturing in Vietnam, Thailand or elsewhere in Southeast Asia. The Taiwan entity is the holding company and the balance sheet; the factories, the workforce and a large share of the operational risk sit abroad. A firm that can only advise on the Taiwan layer will hand you an incomplete picture and a coordination problem.

The 8 Questions to Ask Before You Engage

1. Can you map every approval this deal needs, with realistic timing for each?

Ask for this in writing before you sign an engagement letter. Competent counsel can produce a one-page approval map from a short description of the deal: whether DIR approval is required and on what basis, whether the Taiwan Fair Trade Commission (TFTC) merger filing thresholds are met, whether the target’s industry regulator has a separate consent right, whether Financial Supervisory Commission or exchange obligations apply to a listed target.

What you are testing is not legal knowledge. It is whether they think in terms of the critical path. Regulatory sequencing determines your signing-to-closing period, your conditions precedent, and what you can safely commit to in a letter of intent. A firm that responds with “we will need to look into that” after the initial call is telling you they have not run this exercise recently.

2. Have you obtained DIR approval in my target’s specific sector?

Sector experience with the DIR matters more than general M&A volume. The review is discretionary in practice: the same investment structure receives different treatment depending on the industry, the identity of the ultimate beneficial owners, and how the application characterises the transaction. Counsel who have filed repeatedly in your sector know which supporting documents preempt follow-up queries and which framings invite them.

Ask directly: how many DIR applications have you filed in this industry in the past three years, and what was the longest review period you experienced? The second half of the question is more revealing than the first.

3. How will you test my ownership chain for PRC-investor classification?

This should prompt a specific methodology, not reassurance. The right answer describes a look-through analysis of your acquiring structure: direct and indirect shareholding percentages at every tier, control rights held through contract rather than equity, the composition of any fund investors, and the treatment of listed-company shareholders whose identity you may not fully know.

The consequence of getting this wrong is not a fine. It is a rejected application after months of process, or in the worst case a completed transaction unwound. If counsel treat this as a box-ticking exercise, they have not seen it go wrong.

4. Do we trigger a TFTC merger filing under the thresholds as amended in January 2026?

The Taiwan Fair Trade Commission adopted revised turnover thresholds at its Commissioners’ Meeting on 21 January 2026, effective on promulgation later that month. The thresholds were raised, not lowered — a point on which several online summaries are simply wrong, so verify against the TFTC’s own published figures rather than a secondary source.

Under the amended framework, a filing is required where combined global turnover exceeds NT$50 billion with at least two parties each generating at least NT$3 billion in Taiwan; or, for non-financial enterprises, where one party generates at least NT$20 billion in Taiwan turnover and another at least NT$3 billion; or, for financial enterprises, where one party generates at least NT$40 billion in Taiwan turnover and another at least NT$3 billion. Turnover is aggregated across the corporate group. For foreign enterprises, only sales in and into Taiwan count.

Filing obligations can be triggered by acquiring one-third or more of a target’s voting shares, by asset or business-unit transfers, and by establishing jointly controlled entities. Ask counsel to run the calculation on your actual group figures early — the aggregation rules catch buyers who assumed a small target meant no filing.

5. Who performs the due diligence, in which languages, and against what checklist?

Legal due diligence in Taiwan is document-heavy and almost entirely in Traditional Chinese: corporate records, land and building registrations, labour contracts and work rules, environmental permits, tax filings, IP registrations, related-party arrangements. If the target has overseas operations, add Vietnamese or Thai labour files, land use rights and factory licences.

Ask who is actually reading these documents. Some firms staff diligence with junior associates and deliver a red-flag report that lists issues without quantifying them. What you need is a report that translates findings into price adjustment, indemnity, condition precedent, or walk-away — and that covers the offshore subsidiaries with the same rigour as the Taiwan parent.

Ask to see a redacted sample diligence report. Firms that do this work well will show you one.

6. Will you advise on structure and tax together, or only draft the SPA?

Share purchase, asset purchase, statutory merger and triangular merger under the Business Mergers and Acquisitions Act each carry different tax outcomes, different approval requirements and different treatment of the target’s liabilities and licences. Choosing among them is not a tax question or a legal question; it is both.

Foreign sellers and foreign buyers both face Taiwanese withholding obligations on various payment flows, and treaty relief where Taiwan has a double taxation agreement generally must be applied for in advance with a certificate of tax residency — claiming it retroactively is slow and uncertain. Ask counsel how they coordinate with tax advisers and at what point in the process. The answer should be “before the letter of intent,” not “during closing mechanics.”

7. What is your plan for employees and work rules?

Taiwanese labour law protects employees in a transfer of undertaking, and the mechanics differ significantly between a share acquisition (where the employer entity is unchanged) and an asset or business transfer (where employees must be offered continued employment and those who decline may be entitled to severance). Work rules, pension arrangements and accrued leave all need to be quantified in diligence.

Where the target has Vietnamese or Thai operations, the analysis multiplies. Vietnamese labour law imposes its own consultation and severance requirements on business transfers; Thai law has separate rules again. Buyers routinely underestimate this and discover the liability after signing.

8. Who is my day-to-day contact, and what happens if this becomes a dispute?

Two questions in one. On staffing: ask which named lawyer will answer your email at 9pm during the closing week, and whether that person has closed a deal of this shape before. Pitch partners and delivery teams are frequently different people.

On disputes: post-closing claims — breach of warranty, undisclosed liabilities, earn-out disagreements — are where the value of the SPA is actually tested. Ask whether the firm handles the arbitration or litigation itself or refers it out. A firm that will have to live with the dispute drafts the warranties differently from one that will not.

What M&A Legal Fees Look Like in Taiwan

The four fee models

Hourly billing dominates on complex or unpredictable mandates. Published rate data for the Taiwanese market is thin; general commercial practice in Taipei is commonly quoted in the range of NT$7,000 to NT$12,000 per hour depending on seniority, with M&A specialists and international-facing firms billing at or above the top of that band, and the largest Taipei firms quoting international clients in US dollars at materially higher rates.

Fixed fee by workstream is increasingly common and, for most mid-market buyers, preferable. The deal is broken into discrete deliverables — diligence report, DIR application, TFTC filing, SPA drafting and negotiation, closing — each with its own price. You get budget certainty and can decline workstreams you do not need.

Capped fee blends the two: hourly billing with an agreed ceiling per workstream. This is a fair compromise where scope is genuinely uncertain, such as diligence on a target with unknown liabilities.

Retainer plus deal fee suits acquirers running a programmatic buy-and-build strategy in Taiwan, where a monthly retainer covers pipeline screening and structuring advice, with transaction fees layered on when a deal proceeds.

Success fees calculated as a percentage of deal value are not the Taiwanese legal norm and should prompt questions about who is bearing what risk.

What actually drives the number

Cost correlates poorly with headline deal value and strongly with these five factors:

• — Number of regulatory tracks. A private, non-sensitive, single-jurisdiction target requiring only DIR approval is a fraction of the cost of a listed target triggering tender offer rules, FSC involvement and a TFTC filing simultaneously.
• — Diligence scope. Number of legal entities, number of jurisdictions, volume of contracts, presence of real property, and whether records are organised.
• — Structural complexity. A straightforward share purchase versus a triangular merger with a newly incorporated Taiwan vehicle and offshore holding layer.
• — Counterparty sophistication. Negotiating against a founder-owner with local counsel is a different exercise from negotiating against a private equity seller with an aggressive SPA precedent.
• — Language load. Bilingual drafting, translation of diligence materials, and interpretation at negotiation all consume real hours.

Reading a fee proposal properly

Four things to check. First, is the scope defined by deliverable or by phase? “Due diligence” is not a scope; “a written diligence report covering the six areas listed in Schedule 1, delivered within four weeks of data room access” is. Second, what is expressly excluded? Regulatory filings, tax advice, offshore subsidiary review and post-signing disputes are the usual carve-outs. Third, how are disbursements handled — translation, government fees, notarisation and courier costs add up. Fourth, what happens if the deal dies at diligence? A proposal that does not address abort scenarios has not been thought through.

The cheapest proposal in an inbound Taiwan deal is frequently the one that scoped the least. Compare scope first, then price.

A Realistic Timeline

For planning purposes: a domestic private-company transaction with no foreign investment element can move from signing to closing in roughly eight to twelve weeks. A cross-border acquisition requiring DIR foreign investment approval, and a TFTC merger filing where thresholds are met, more commonly runs four to six months from signing. Transactions in sensitive sectors, or where national security review is engaged, can extend to nine months or beyond.

These are approval-driven periods, not negotiation periods. Add diligence and negotiation ahead of them.

How Louis Group Approaches Taiwan M&A

Louis Group is a cross-border legal advisory group with approximately fifty lawyers across offices in Taiwan, Thailand and Vietnam. Our approach to inbound Taiwan M&A reflects three convictions formed from the transactions we have handled.

We treat the target as a group, not a Taiwanese entity. Where a Taiwan target operates factories in Vietnam or Thailand — which is the norm in the manufacturing sectors foreign buyers most often pursue — we conduct the diligence on those operations with our own lawyers, admitted in those jurisdictions, working from the same checklist and reporting into the same document. Buyers do not appoint three firms, reconcile three formats, or absorb the cost of coordinating between them. Nor do they discover an unfunded Vietnamese severance liability after signing because the Taiwan diligence stopped at the Taiwan border.

We run the approval analysis before the letter of intent. Structuring, DIR sector analysis, PRC ownership look-through and TFTC threshold calculation are front-loaded, because those are the variables that constrain the deal. Discovering at month three that the acquiring vehicle triggers a classification problem is an expensive way to learn something that a two-week analysis would have surfaced.

We work in the languages of the deal. Our teams advise in Traditional Chinese, English, Vietnamese, Thai and Japanese. Diligence documents, negotiation and regulatory filings are handled directly rather than through a translation layer, which removes both cost and a common source of error.

The group is led by its founding attorney, Raymond Yu (俞伯璋), who practises across the group’s Taiwan, Thailand and Vietnam offices in cross-border corporate and transactional matters.

Frequently Asked Questions (FAQ)

Do foreign buyers need government approval to acquire a Taiwanese company?

Yes. Foreign investors must obtain prior approval from the Department of Investment Review (DIR) at the Ministry of Economic Affairs before completing an acquisition of a Taiwanese company. This applies to private targets whenever a direct shareholder of the Taiwan entity changes as a result of the transaction. For companies listed on the Taiwan Stock Exchange or Taipei Exchange, DIR approval is required where a foreign investor acquires 10% or more of share capital in a single transaction. Separately, the Statute for Investment by Foreign Nationals maintains a negative list of sectors where foreign investment is prohibited or capped, including certain defence, telecommunications, utilities and transportation businesses. Approval is a condition precedent to closing, not a post-completion formality, and should be built into the transaction timetable from the outset.

What are the current TFTC merger filing thresholds in Taiwan?

The Taiwan Fair Trade Commission adopted revised turnover thresholds on 21 January 2026, raising them from the levels set over a decade earlier. A pre-merger filing is required where: combined global turnover exceeds NT$50 billion and at least two parties each generate NT$3 billion or more in Taiwan turnover; or, for non-financial enterprises, one party generates at least NT$20 billion in Taiwan turnover and another at least NT$3 billion; or, for financial enterprises, one party generates at least NT$40 billion in Taiwan and another at least NT$3 billion. Turnover is calculated on a group-consolidated basis. For foreign enterprises, only sales made in Taiwan and directly into Taiwan are counted. The separate monopoly-assessment exemption threshold was raised from NT$2 billion to NT$3 billion at the same meeting.

How much do M&A lawyers charge in Taiwan?

Taiwanese M&A counsel bill through four principal models: hourly rates, fixed fees by workstream, capped fees, and retainer-plus-deal-fee arrangements. Published rate data is limited; general commercial hourly rates in Taipei are commonly quoted between NT$7,000 and NT$12,000 depending on seniority, with M&A specialists and the largest international-facing firms billing above that band, frequently in US dollars for foreign clients. Total cost correlates far more closely with the number of regulatory approval tracks, diligence scope and structural complexity than with headline deal value. For budget certainty, request a fixed fee broken down by deliverable — diligence report, DIR application, TFTC filing, SPA drafting, closing — and confirm in writing what is excluded and how an aborted deal is treated.

How long does it take to close an acquisition in Taiwan?

Timing is driven by regulatory approvals rather than negotiation. A domestic private-company transaction with no foreign investment element can typically close within eight to twelve weeks of signing. A cross-border acquisition requiring DIR foreign investment approval, and a TFTC merger filing where thresholds are met, more commonly takes four to six months from signing to closing. Where the target operates in a sensitive sector, or where national security review or inter-agency consultation is triggered, nine months or longer is realistic. Public-company acquisitions add Securities and Exchange Act obligations, including mandatory tender offer rules engaged at 20% or more of a public company’s total issued shares acquired within a 50-day period. Diligence and negotiation run ahead of these periods.

Can a mainland Chinese-connected investor acquire a Taiwanese company?

Investors with mainland Chinese connections are reviewed under a separate and materially stricter regime than other foreign investors, with restrictions on strategic industries and substantially longer review timelines. The critical point for foreign buyers is that classification is assessed through the ownership chain rather than at the level of the immediate acquiring entity. Indirect shareholding, contractual control rights and fund investors several tiers up can all result in a buyer being treated as a mainland Chinese investor even where the acquiring vehicle is incorporated in Europe or North America. This analysis should be conducted before the letter of intent, because restructuring an acquisition vehicle after an application has been filed is significantly more difficult than structuring it correctly at the outset.

Should the same firm handle Taiwan and Southeast Asian due diligence?

Where a Taiwan target holds subsidiaries or manufacturing operations in Vietnam, Thailand or elsewhere in the region — which is common in electronics, precision components and industrial manufacturing — using a single firm across all relevant jurisdictions materially reduces both cost and risk. Separate local counsel in each jurisdiction produce reports in different formats, on different checklists, at different times, leaving the buyer to reconcile them. Gaps between scopes are where undisclosed liabilities survive: unfunded severance obligations, defective land use rights, unlicensed factory operations. A unified diligence workstream applying one standard across the group, with findings quantified into a single risk register, gives the buyer a usable basis for price adjustment and indemnity negotiation.
