Taiwan M&A 2026: What the Fair Trade Commission's Merger‑control Changes Mean for Deals

The Taiwan merger control changes 2026 represent the most consequential overhaul of the island’s merger‑filing regime in more than a decade. On 21 January 2026 the Taiwan Fair Trade Commission (TFTC) formally adopted amendments to the Thresholds and Calculation of Sales Amount for Enterprises Filing Merger Notifications, which took effect on 28 January 2026 following publication in the Executive Yuan Gazette. The amendments raise turnover‑based filing thresholds for both financial and non‑financial enterprises while a separate, still‑pending draft proposal contemplates significant changes to the market‑share filing trigger.

For in‑house counsel, M&A advisors and private‑equity deal teams with Taiwan exposure, the practical effect is immediate: transactions that previously required a mandatory TFTC merger notification may now fall below the new thresholds, while others, particularly in digital and platform sectors, could be caught by evolving market‑share rules that are still being refined.

Executive Summary, What Changed and What Deal Teams Must Do Now

Before diving into detailed analysis, here is a snapshot of the key developments and what they require of transaction professionals:

• Threshold increases enacted. The TFTC adopted revised sales‑amount thresholds on 21 January 2026. The amendments became effective on 28 January 2026 upon publication in the Executive Yuan Gazette.
• Financial vs non‑financial distinctions updated. Separate, differentiated thresholds continue to apply to financial institutions and non‑financial enterprises, with upward adjustments to both sets of figures.
• Market‑share threshold under review. A draft proposal to remove or substantially adjust the market‑share filing trigger is under active TFTC consultation. As of April 2026, this proposal has not been enacted.
• Filing forms and guidance refreshed. The TFTC has released updated merger‑notification forms and filing directions reflecting the new thresholds.
• Who is affected. Any enterprise, domestic or foreign, contemplating a share acquisition, asset purchase, joint venture or business combination that meets the revised thresholds or potentially triggers the market‑share test.

Five actions for deal teams in the next 14 days

1. Re‑run threshold calculations on every pending or pipeline transaction against the 28 January 2026 figures.
2. Assess whether any deal that previously fell below the turnover threshold now clears it, and vice versa.
3. Review market‑share exposure: even if turnover thresholds are not met, the existing market‑share test still applies until any draft amendment is formally enacted.
4. Update SPA and term‑sheet templates to reflect revised regulatory‑condition and long‑stop‑date language.
5. Brief external Taiwan competition counsel on any cross‑border carve‑out or series of transactions to confirm filing status.

Legal Basis: The Fair Trade Act and TFTC Authority

Taiwan’s merger‑control regime derives from the Fair Trade Act (公平交易法), the principal competition statute administered by the TFTC. The Act establishes a mandatory pre‑merger notification system: enterprises that meet prescribed thresholds must file with the TFTC and may not complete the transaction until clearance is obtained or the statutory waiting period expires. The TFTC is an independent government agency under the Executive Yuan with broad powers to investigate, approve, conditionally approve, or prohibit mergers that may substantially lessen competition or otherwise harm the public interest.

Key statutory provisions

The core merger‑control provisions are found in Articles 10 through 13 of the Fair Trade Act. Article 10 defines the types of “combinations” (mergers) that fall within the regime, including share acquisitions, asset transfers, joint operations, and the assumption of another enterprise’s business or assets. Article 11 sets out the obligation to file a notification when the enterprises involved meet the thresholds prescribed by the TFTC. Article 13 empowers the TFTC to prohibit or impose conditions on mergers that create competition concerns. The specific numeric thresholds are not set in the statute itself but are delegated to the TFTC, which issues them as subordinate regulations, the Thresholds and Calculation of Sales Amount for Enterprises Filing Merger Notifications.

This delegation is what enabled the TFTC to enact the January 2026 changes without a legislative amendment to the Fair Trade Act itself.

The Fair Trade Act amendments Taiwan practitioners must be familiar with also include the penalty provisions. Under the Act, completing a notifiable merger without filing, or prior to receiving clearance, can result in administrative fines and, in serious cases, an order to unwind the transaction. These enforcement teeth make accurate threshold analysis a commercial priority rather than a mere compliance formality.

Taiwan Merger Control Changes 2026: Thresholds, Forms and Guidance

The centrepiece of the 2026 amendments is the upward revision of the turnover‑based merger filing thresholds Taiwan enterprises and acquirers must apply. The TFTC’s rationale, as indicated in practitioner commentary and the Commission’s own publications, is to recalibrate thresholds to reflect inflation, GDP growth and evolving market structures, thereby focusing the Commission’s review resources on transactions that genuinely raise competition concerns.

Note: The precise NTD amounts for each threshold category are published on the official TFTC page for the Thresholds and Calculation of Sales Amount and in the Executive Yuan Gazette entry for the 28 January 2026 amendments. Deal teams should confirm exact figures directly from those primary sources before relying on secondary summaries.

Changes to filing forms and guidance

Alongside the threshold revisions, the TFTC updated its merger‑notification form templates and filing directions. The updated documents reflect the new threshold figures and include clarified instructions on calculating “sales amount” for enterprises engaged in multiple business lines or operating across jurisdictions. The TFTC’s merger filing directions and downloadable templates are available on the Commission’s English‑language documentation portal. Counsel preparing a TFTC merger notification should download the current forms rather than relying on older versions, as the Commission has signalled that incomplete filings based on superseded templates will be returned without review.

Market‑Share Threshold: Proposed Removal and Practical Impact

Separate from the enacted threshold increases, the TFTC has circulated a draft proposal that would fundamentally change how the market‑share filing trigger operates. Under the existing rules, a merger notification is required where any party holds one‑quarter or more of the relevant market, regardless of whether turnover thresholds are met. The draft proposal, which remains under consultation as of April 2026, contemplates either removing the market‑share threshold entirely or raising it to a level that would significantly narrow its application.

Industry observers expect that if the market‑share threshold is abolished, the practical effect will be to remove a filing obligation from a substantial number of smaller transactions, particularly in fragmented or fast‑growing sectors, while concentrating TFTC oversight on the largest deals captured by the turnover test alone. Conversely, early indications suggest that some platform and digital‑economy transactions with relatively low turnover but high market share could escape the notification net, a prospect that has drawn commentary from consumer‑advocacy groups and the TFTC itself.

Three internal tests counsel should run now

1. Turnover‑only test. Apply the 28 January 2026 turnover thresholds. If the transaction clears both the combined and individual thresholds, a filing obligation exists regardless of market share.
2. Market‑share backstop test. Even where turnover thresholds are not met, assess whether any party holds one‑quarter or more of the relevant market under the existing (still‑enacted) rule. Until the draft proposal is formally adopted, this trigger remains live.
3. Forward‑looking sensitivity test. Model the impact of the proposed market‑share removal on the deal. If the transaction would be notifiable only under the market‑share test, monitor TFTC announcements closely and build flexibility into closing conditions and long‑stop dates.

For deal teams evaluating competition law Taiwan 2026 implications, the dual‑track nature of these changes, one set enacted, one still proposed, demands a conservative, belt‑and‑braces approach to filing analysis.

Who Must File Now, Entity and Transaction Types

Taiwan M&A compliance 2026 obligations turn on two variables: the nature of the enterprise and the type of transaction. The following table summarises the filing landscape under the current rules (incorporating the 28 January 2026 threshold amendments).

A recurring pitfall is the failure to aggregate turnover across all enterprises within the same corporate group. The TFTC’s calculation methodology requires that sales amounts be computed on a group‑wide basis, not merely for the immediate acquiring or target entity. For cross‑border acquirers, this means worldwide turnover may push the transaction above the threshold even when the Taiwan target’s revenue alone would not.

Cross‑Border M&A Taiwan: Timing, Valuation and Jurisdictional Traps

Cross‑border M&A Taiwan transactions raise unique challenges under the amended regime. Foreign acquirers must navigate turnover‑attribution rules that differ from those in the EU, the United States and other familiar jurisdictions. The TFTC’s approach to calculating “sales amount” for overseas enterprises can produce unexpected filing obligations, particularly in carve‑out and platform transactions where revenue streams are geographically dispersed.

Carve‑out valuation and turnover allocation

When a foreign buyer acquires a Taiwan business unit that is not a separate legal entity, the threshold calculation requires allocating revenue to the carved‑out operations. The TFTC expects acquirers to provide audited or verifiable financial data supporting the allocation. In practice, this means deal teams should:

• Prepare stand‑alone financial statements for the target business unit as early as possible in the transaction process.
• Engage local auditors or accounting advisors who understand the TFTC’s methodology for revenue attribution.
• Be prepared for TFTC information requests seeking granular product‑line or customer‑segment revenue data from the seller.

Series of transactions and attribution rules

The TFTC may treat a series of related acquisitions, for example, a phased acquisition of shares or a simultaneous purchase of a target’s equity and key assets, as a single combination for notification purposes. This attribution rule is particularly relevant for private‑equity roll‑up strategies and consortium deals. Deal structuring Taiwan merger control considerations must therefore account for the full arc of the investment, not merely the immediate step.

Data and evidence the TFTC expects from overseas parties

Foreign acquirers should anticipate requests for:

• Worldwide consolidated financial statements (typically for the most recent two to three fiscal years).
• An organisational chart showing the ultimate beneficial owner and all entities in the control chain.
• Market‑share data for the relevant product and geographic markets in Taiwan, even where the acquirer has no direct Taiwan presence.
• Details of any parallel merger‑control filings in other jurisdictions and their status.

Failure to supply complete data is among the most common reasons for TFTC completeness rejections, which can reset the review clock and materially delay closing.

Compliance and Filing Process: Timeline, Documents and Fast‑Track Tips

Understanding the procedural timeline is critical for Taiwan M&A compliance 2026. The following table outlines the key milestones from deal signing through TFTC clearance.

Required documents checklist for a TFTC merger notification

• Completed merger‑notification form (current version, downloaded from the TFTC portal).
• Basic registration documents for all filing parties (company registration certificates, articles of incorporation).
• Audited financial statements for the most recent two to three fiscal years for each party.
• Group structure chart showing ultimate beneficial ownership and all related enterprises.
• Market‑share data and a description of the relevant product and geographic markets.
• A copy of the transaction agreement (SPA, share subscription agreement, JV agreement) or the most recent draft if not yet executed.
• Power of attorney authorising Taiwan counsel to act on behalf of foreign filing parties.
• Any economic or industry reports relied upon in the market‑share analysis.

Practical tips to speed clearance

• Pre‑notification consultation. The TFTC informally accepts pre‑notification discussions. Use them to identify potential issues and tailor the filing accordingly.
• Front‑load market data. TFTC case teams consistently report that market‑share data is the area where filings are most often incomplete. Investing in robust data collection before filing pays dividends in review speed.
• Coordinate multi‑jurisdictional filings. If the transaction requires parallel filings in other jurisdictions, align timing to avoid situations where a TFTC clearance delay becomes the critical path.

Deal‑Structuring Playbook: Options to Manage Filing Risk

Smart deal structuring Taiwan merger control strategies can materially reduce filing risk or at least ensure that any required notification does not derail the transaction timetable. The following options should be evaluated at the term‑sheet stage.

• Holdco interposition. Structuring the acquisition through a newly established Taiwan or offshore holding company can, in some scenarios, alter the turnover figures attributable to the acquiring enterprise. However, the TFTC’s group‑wide calculation methodology means that a purely artificial holdco will not avoid a filing obligation. The structure must have genuine commercial substance.
• Limited carve‑outs and ring‑fencing. Where a target has both competition‑sensitive and non‑sensitive business lines, acquiring only the non‑sensitive operations may bring the transaction below the market‑share trigger. This requires precise scoping in the SPA and verifiable revenue data to support the narrower calculation.
• Phased acquisitions with genuine independence. Acquiring a minority stake below the one‑third voting‑share threshold in a first phase, followed by a subsequent acquisition, may defer the filing obligation, but counsel must carefully assess whether the TFTC will aggregate the phases as a single combination.
• Conditionality and long‑stop dates. Every SPA involving a potentially notifiable Taiwan transaction should include a TFTC clearance condition precedent and a long‑stop date that accommodates the full Phase I and Phase II review timeline (up to 90 calendar days). Consider a break fee that allocates regulatory risk appropriately.

Drafting flags for SPAs and term sheets

Counsel should review the following clauses for alignment with the 2026 changes:

1. Regulatory condition precedent. Confirm it expressly references TFTC clearance (not just “all applicable antitrust clearances”) and defines clearance to include unconditional approval, conditional approval accepted by both parties, or expiry of the waiting period without prohibition.
2. Cooperation covenant. Require both parties to cooperate fully in the TFTC notification process, including providing financial data and market‑share information within specified timeframes.
3. Interim operating covenants. Ensure the target’s business is conducted in the ordinary course during the review period, as the TFTC may view pre‑closing integration as gun‑jumping.
4. Remedies and commitments clause. Address whether and to what extent a party is obligated to offer behavioural or structural remedies to secure conditional TFTC approval.

Sector Focus: Fintech and Platform Transactions

The ongoing review of the market‑share filing threshold has particular significance for fintech and platform businesses. These enterprises often exhibit high market concentration in narrowly defined relevant markets despite relatively modest turnover, a profile that the current market‑share test is designed to catch. If the TFTC proceeds with removing or raising the market‑share trigger, the likely practical effect will be that a meaningful number of digital‑economy transactions escape mandatory notification, even where they materially alter the competitive landscape.

Industry observers expect the TFTC to address this gap, potentially through sector‑specific guidance or a supplementary “deal value” threshold, but no formal proposal to that effect has been published as of April 2026. In the interim, deal teams in the fintech and platform space should consider three sector‑specific tactics:

• Voluntary notification. Even where not strictly required, a voluntary filing can provide legal certainty and pre‑empt enforcement risk if the TFTC later determines that the transaction was notifiable.
• Market‑definition analysis. Invest in a rigorous, defensible market‑definition analysis that anticipates the TFTC’s likely approach to digital and two‑sided markets.
• Engagement with TFTC policy consultations. Participate in the ongoing consultation on the market‑share threshold to shape the outcome and gain early visibility on the Commission’s direction.

Key Takeaways and Recommended Checklist for Deal Teams

The following ten‑point checklist distils the practical implications of the Taiwan merger control changes 2026 into actionable steps for transaction professionals:

1. Confirm the current threshold figures from the official TFTC publication (effective 28 January 2026).
2. Re‑assess every pending and pipeline transaction against the revised turnover thresholds.
3. Apply the market‑share test under the existing rules, do not assume the draft removal proposal is in effect.
4. Calculate turnover on a group‑wide basis, including all related enterprises worldwide.
5. Prepare stand‑alone financials for any carved‑out business units.
6. Download the latest TFTC notification form and filing directions before preparing any submission.
7. Build TFTC review time (up to 90 calendar days for Phase I + Phase II) into SPA long‑stop dates.
8. Include express TFTC clearance conditions, cooperation covenants and interim operating restrictions in transaction documents.
9. Consider voluntary notification for high‑market‑share transactions that may fall below turnover thresholds.
10. Engage experienced Taiwan competition counsel for any cross‑border deal or transaction in a sector where TFTC scrutiny is likely. The GLE lawyer directory provides access to specialists across Taiwan’s business and competition law landscape.
