A practitioner's guide to transfer pricing in Taiwan: Article 43-1 of the Income Tax Act, the Ministry of Finance's arm's length Regulations, documentation thresholds and safe harbours, APAs and MAP, and the 15% minimum tax from 2025.
Policy and rule-making sit centrally with the MOF and the Taxation Administration. Assessment, audit and receipt of the master file and CbC report are handled by the Taipei, Northern Area, Central Area, Southern Area and Kaohsiung bureaus, each of which publishes its own practical guidance.
Ministry of Finance, R.O.C. — official portalThe provision applies where an enterprise is in a controlled or subordinate relationship with another enterprise at home or abroad and the allocation of income, costs, expenses or profit and loss avoids or reduces tax. The requirement of Ministry approval before an adjustment is finalised is a real procedural check on the assessing bureau.
Income Tax Act, Art. 43-1Full title: Regulations Governing Assessment of Profit-Seeking Enterprise Income Tax on Non-Arm's-Length Transfer Pricing, made under Article 80(5) of the Income Tax Act. The 2020 amendment expanded the intangibles rules; no later amendment appears on the MOF regulation system or the national law database.
TP Regulations, Art. 1 and amendment history (last amended 28 Dec 2020)Taiwan is neither an OECD member nor an Inclusive Framework member, so it has never been within scope of the country-profile series. The Regulations nowhere cite the Guidelines — they are a self-contained domestic code drafted along OECD and BEPS Action 13 lines, and OECD material is persuasive background only.
TP Regulations (complete text, no OECD reference); OECD country-profile series (Taiwan not included)Articles 3 to 5 cover transfer and use of tangible assets, transfer and use of intangibles, provision of services, use of funds (loans, advances, guarantees, deferred collection) and any further category the MOF designates. Purely domestic related-party transactions are within the rules, not only cross-border ones.
TP Regulations, Arts. 3–5The same standard binds the tax authority on audit. Two adjacent anti-avoidance regimes differ in status: the CFC rule in Income Tax Act Article 43-3 was brought into effect by the Executive Yuan from 1 January 2023, while the place-of-effective-management residence rule added as Article 43-4 on 27 July 2016 sits on the statute book but has never been brought into force — Article 126 reserves its commencement date to the Executive Yuan, which has still not set one.
TP Regulations, Art. 6; Income Tax Act, Arts. 43-3, 43-4 and 126 (Art. 43-4 commencement date not yet fixed)Methods are prescribed by transaction type across Articles 9 to 19. Article 9 requires best-method selection on the degree of comparability and the quality of the data and assumptions rather than a fixed hierarchy.
TP Regulations, Arts. 9–19Article 7 sets this expressly, and the Northern Area Bureau has publicly identified company-wide profitability testing as a leading methodological error. Any aggregated tested party needs a documented interlinkage rationale in the report.
TP Regulations, Art. 7A result outside the range is adjusted to the median of all comparable results — not to the nearer edge — so the width of the range and the defensibility of every comparable have direct cash consequences.
TP Regulations, Art. 7Article 18 defines the tested party as the participant for which reliable comparable data can be obtained with the fewest and most reliable adjustments — in substance one not owning valuable unique intangibles. Further indicators require MOF approval.
TP Regulations, Art. 18Where current-year comparable data cannot be obtained, three continuous preceding years may be used instead. Taiwanese benchmarking sets are therefore normally built on three-year weighted averages.
TP Regulations, Art. 18Article 8 lists market size and growth, market level, market share, competition, purchasing power, available alternatives, regulation, industry conditions and transport costs. Where a significant difference exists, a reasonable adjustment must eliminate its effect before the comparable can be used — the gate a pan-Asian set must pass.
TP Regulations, Art. 8Content: business and industry overview, group structure, transaction summary, comparability and functional/risk analysis, method selection, arm's length conclusion and underlying agreements. Where the group is profitable but the Taiwan entity reports a loss, the report must analyse the cause of the loss.
TP Regulations, Art. 22; Income Tax Act, Art. 71Transaction-level carve-outs also allow substitute evidence for particular dealings — government and state-owned counterparties, small-value transactions, margins above the published industry profit standard, and intercompany financing at or above the Bank of Taiwan base lending rate. Relief is from the full report, not from Article 43-1: substitute documents showing an arm's length result are still required.
MOF ruling Tai-Cai-Shui No. 09704555160 (6 Nov 2008, as updated), interpreting TP Regulations Art. 22Content covers group organisational structure, business description, intangibles strategy and ownership, intra-group financing and the consolidated financial and tax position. Delivered to the local bureau within one year of the accounting year end.
TP Regulations, Art. 21-1; MOF ruling Tai-Cai-Shui No. 10804651540 (10 Dec 2019), superseding the safe-harbour ruling of 13 Dec 2017Secondary local filing is triggered where the foreign UPE has no CbCR obligation, or files but there is no effective exchange arrangement with Taiwan by the deadline, or the report cannot in fact be obtained. MOF ruling Tai-Cai-Shui No. 10804651540 of 10 December 2019 excuses a Taiwan constituent entity meeting the master file exemption standard — own revenue under NT$3bn or cross-border controlled transactions under NT$1.5bn — and applies from the FY2017 (ROC 106) return onwards.
TP Regulations, Art. 22-1; MOF ruling Tai-Cai-Shui No. 10804651540 (10 Dec 2019), superseding the safe-harbour ruling of 13 Dec 2017Constituent entities must also identify the ultimate parent and disclose master file and CbC report information. The MOF filing reminder refers to pages B2–B6 while published form packages run B1–B7; page lettering shifts between tax years, so work from schedule names rather than page numbers.
TP Regulations, Art. 21; MOF filing reminder and NTB return-form packagesWhere several group members are in Taiwan, one may be designated to file for all. In practice both are lodged through the corporate income tax e-filing system with the return package, which carries prescribed CbC forms and a master file cover sheet.
TP Regulations, Arts. 21-1 and 22-1; NTB return-form packageThe same one-month-plus-one-month rule applies where a Taiwan member is called on to lodge a CbC report under the secondary filing rule. Documentation must be contemporaneous — it cannot be built after the notice arrives.
TP Regulations, Arts. 22 and 22-1The one-month translation window for the master file is extendable once, by up to one further month. English may be accepted for the TP report and the CbC report only where the authority approves.
TP Regulations, Arts. 21-1, 22 and 22-1Industry profit standards ignore the taxpayer's actual functions and risks, which is the practical reason Taiwanese groups prepare reports even when close to a safe harbour. Article 33(3) also exposes the taxpayer to the Tax Collection Act production penalty.
TP Regulations, Art. 33; Income Tax Act, Art. 83Small in absolute terms — the real exposure from an empty file is the assessment method under Article 33 and the loss of penalty protection under Article 34.
Tax Collection Act, Art. 46(1) reported price at least double, or no more than 50%, of the assessed arm's length price; (2) income increase reaching 10% of assessed annual income and 3% of net operating revenue; (3) failure to produce the Article 22 report with no other arm's length evidence; (4) undisclosed controlled transactions where the adjustment reaches 5% of assessed annual income and 1.5% of net operating revenue (千分之十五, fifteen per thousand). Article 110 itself runs to twice the tax underpaid, or three times where no return was filed.
TP Regulations, Art. 34; Income Tax Act, Art. 110No transfer-pricing-specific period applies. The period does not run out while an administrative appeal or litigation is unresolved (a further year runs from the date a remitted assessment becomes final), and is suspended for six months in force majeure cases.
Tax Collection Act, Art. 21In its filing-season release of 12 May 2026 the National Taxation Bureau of the Northern Area named these as the errors it most often finds. The first three are disclosure failures as well as pricing failures, which opens the fourth Article 34 penalty gateway.
National Taxation Bureau of the Northern Area, 'Analysis of common errors in transfer pricing disclosure', 12 May 2026Application must be made before the end of the first accounting year to be covered — a hard cut-off that catches groups deciding on certainty in arrears. A pre-filing conference may be requested up to three months before the year end.
TP Regulations, Arts. 23 and 24The statutory review clock does not bind bilateral or multilateral APAs under a tax treaty. There is no application or user fee, an annual compliance report is due in each covered year's filing period, and critical-assumption changes must be notified within one month.
TP Regulations, Arts. 23, 26–32The only backward reach is Article 29(3), which lets the arrangement be applied to a covered year already filed before signature by way of an impact report. Historic years must be addressed through MAP or the domestic appeal route instead.
TP Regulations, Arts. 29 and 31For financial holding companies the approving authority is the competent authority under Article 50 of the Financial Holding Company Act. Cross-border corresponding relief is available only through MAP under an applicable income tax agreement.
TP Regulations, Art. 35Articles 33 and 35 address only the primary and domestic corresponding adjustment, and no secondary mechanism appears anywhere in the Regulations. The one place cash settlement of related-party balances is regulated is the year-end one-time adjustment ruling.
TP Regulations, Arts. 33 and 35 (no secondary adjustment provision)Governed by the Regulations Governing Application of Agreements for the Avoidance of Double Taxation and the MOF's Operational Directions of 25 June 2018 (amended 25 November 2020). Qualifying cases expressly include TP corresponding adjustments and bilateral or multilateral APAs; foreign-language documents need Chinese translation unless waived.
MOF Operational Directions for the Mutual Agreement Procedure (2018, amended 25 Nov 2020)The MOF pre-announced the revised collection rate for the profit-seeking enterprise basic tax on 28 August 2024, applying 15% to Taiwan entities of groups meeting the EUR 750m global minimum tax threshold and leaving others at 12%, within the 12–15% band set under Article 8 of the Income Basic Tax Act. This is not a QDMTT; confirm the final Executive Yuan order before treating it as settled law.
MOF/Taxation Administration release, 28 Aug 2024; Income Basic Tax Act, Art. 8Taiwan sits outside the Inclusive Framework and did not sign up to the January 2024 report. Routine distributors are still tested under the ordinary comparable profits method with a full benchmarking study, and there is no MOF guidance on whether Taiwan would accept an Amount B outcome applied by a counterparty jurisdiction.
TP Regulations (no Amount B provision); method rules at Arts. 9–19Importers must lodge a deposit and provisional invoice with Customs and submit final documentation within one month of year end so duty and VAT are corrected; other adjustments are declared with the final-period VAT, commodity tax or withholding return and supported by a credit note or marked invoice. Full disclosure with the income tax return, including contracts and evidence of the counterparty's matching adjustment, is required.
MOF ruling of 15 Nov 2019, Tai-Cai-Shui No. 10804629000 (applying 自109年度起, from FY2020)Taiwan's transfer pricing regime rests on one statutory sentence and a detailed subordinate code. Article 43-1 of the Income Tax Act allows the tax authority to restate the income of a profit-seeking enterprise where it stands in a controlled or subordinate relationship with another enterprise, at home or abroad, and income, costs, expenses and profit or loss are allocated on non-arm's-length terms so as to avoid or reduce tax. Two features repay attention. The rule reaches purely domestic related-party dealings as readily as cross-border ones. And an adjustment cannot be finalised by the assessing bureau alone: the Ministry of Finance must approve it, a procedural control that shapes how audits are argued and settled.
The operative rules are the Regulations Governing Assessment of Profit-Seeking Enterprise Income Tax on Non-Arm's-Length Transfer Pricing, issued on 28 December 2004 under Article 80(5) of the Income Tax Act. The text in force is the amendment promulgated on 28 December 2020, first applied to the 2020 tax year, which expanded the intangibles provisions. Policy and rule-making sit with the Ministry of Finance and its Taxation Administration; audit, assessment and receipt of documentation sit with the five regional National Taxation Bureaus.
Two neighbouring regimes shape outbound structuring, and their status differs. The controlled foreign company rule in Article 43-3 was brought into effect by the Executive Yuan from 1 January 2023 and is live. The place-of-effective-management residence rule added as Article 43-4 in July 2016 is not: Article 126 leaves its commencement date to the Executive Yuan, which has still not set one, so the provision sits on the statute book without force. Advisers should not plan around a Taiwanese PEM residence test.
One point of orientation matters for anyone arriving from an OECD jurisdiction. Taiwan is neither an OECD member nor in the Inclusive Framework, and there is no OECD Transfer Pricing Country Profile for Taiwan. The Regulations cite the OECD Guidelines nowhere; they are a self-contained domestic code drafted along OECD and BEPS Action 13 lines. They are persuasive background, not law.
Article 6 puts the first obligation on the taxpayer: when it files its annual return, the enterprise must itself test whether its controlled transactions produced an arm's length result. Article 7 supplies the standard — the result unrelated parties would have achieved in comparable uncontrolled transactions in comparable circumstances — and requires evaluation transaction by transaction, with aggregation only where transactions are genuinely interlinked.
Articles 9 to 19 prescribe methods by transaction type: comparable uncontrolled price, the comparable uncontrolled transaction method for intangibles, resale price, cost plus, comparable profits, profit split, an income or valuation-based method for intangibles, and any further method the Ministry approves. Article 9 imposes a best-method selection driven by comparability and the quality of data and assumptions, not a rigid hierarchy.
Three rules govern the benchmarking file. Article 7 defines the arm's length range as the results of applying the chosen method to two or more comparables, narrowed to the interquartile range where comparability information is incomplete; a result outside the range is moved to the median. Article 18 fixes the tested party as the participant for which reliable data can be obtained with the fewest adjustments, lists the permitted profit level indicators — return on operating assets, operating margin, the Berry ratio and net margin on total cost and operating expenses — and requires in principle three continuous years of data. Article 8 does not confine comparables to Taiwan but makes similarity of the regional market an express comparability factor, so an Asia-Pacific set used to cure a thin domestic sample must be defended on market grounds.
Taiwan runs full three-tier documentation, and the tiers behave differently. The transfer pricing report under Article 22 must exist by the date the annual return is filed but is not lodged with it; it is produced on demand. The master file under Article 21-1 and the country-by-country report under Article 22-1 are delivered to the local National Taxation Bureau within twelve months of the year end, in practice through the e-filing package.
Thresholds decide how much of this bites. The Ministry's safe-harbour ruling relieves an enterprise of a full report where annual net operating revenue plus non-operating income is below NT$300 million; where that total is between NT$300 million and NT$500 million and the enterprise claims no exemption or investment credit, uses no loss carryforward and has no cross-border related-party transactions; or where total controlled transactions are below NT$200 million. Transaction-level carve-outs sit alongside — small-value dealings, transactions with government bodies, and intercompany financing priced at or above the Bank of Taiwan base lending rate. Relief is never a licence to price carelessly: substitute documents evidencing an arm's length outcome are still required.
The master file is waived where revenue plus non-operating income is under NT$3 billion or cross-border controlled transactions are under NT$1.5 billion. The CbC report is required of a Taiwan-resident ultimate parent whose prior-year consolidated group revenue reaches NT$27 billion, with secondary local filing where the foreign parent has no obligation or files with no effective exchange route to Taiwan. Both sets of thresholds, and the relief that excuses a Taiwan constituent entity meeting the master file standard from secondary CbCR filing, now sit in MOF ruling Tai-Cai-Shui No. 10804651540 of 10 December 2019, which superseded the safe-harbour ruling of 13 December 2017 and applies from the FY2017 return onwards.
Two operational points close the picture. Documentation is a Chinese-language obligation; the master file may be lodged in English with a translation supplied within one month of written request, extendable once. And Article 21 requires related-party disclosure in the return itself — structure chart, related-party list, transaction summary and detail, and the MNE group member sheet — in the "B" series schedules, whose page lettering shifts between tax years.
Article 33 sets the consequence of an empty file. If the report or acceptable substitutes are produced, the bureau determines the arm's length result under the Regulations. If not, it may assess on whatever information it has gathered, and where none exists and the missing material relates to revenue, cost or expense, it may apply the published industry profit standards under Article 83 of the Income Tax Act. A blunt instrument, and the practical reason documentation gets prepared. On audit the enterprise has one month from service of the written investigation notice to produce, extendable once by up to a further month for good cause.
The direct documentation fine is small — NT$3,000 to NT$30,000 under Article 46 of the Tax Collection Act. The exposure that matters is the under-reporting penalty, and Article 34 is the shield. It confines the Article 110 penalty to four gateways: a reported price at least double or no more than half the assessed arm's length price; an income increase reaching both 10% of assessed annual income and 3% of net operating revenue; failure to produce the Article 22 report with no other evidence of an arm's length result; or undisclosed controlled transactions where the adjustment reaches both 5% of assessed annual income and 1.5% of net operating revenue. That last figure is fifteen per thousand in the Chinese text — a threshold ten times higher than a careless reading suggests, and not easily tripped. Article 110 itself runs to twice the tax underpaid, or three times where no return was filed. Preparing the report and disclosing the transactions removes two of the four gateways outright. Assessment periods are five years where a return was filed on time without fraud and seven otherwise, and do not expire while an appeal or litigation is unresolved.
Article 23 opens the advance pricing arrangement programme to enterprises whose controlled transactions total at least NT$500 million in aggregate or NT$200 million annually, with no significant evasion record in the preceding three years and documentation already prepared. Application must be made before the end of the first year to be covered. A pre-filing conference may be requested up to three months before the year end. Acceptance is notified within one month, Article 24 documents follow within three, and review must complete within a year, extendable by six months and exceptionally a further six; those limits do not bind bilateral or multilateral cases. An arrangement covers three to five years, renewable for up to five more where the facts have not materially changed. There is no user fee, an annual compliance report is required, and there is no rollback.
Where an adjustment has been approved by the Ministry and become final and the counterparty is a Taiwan taxpayer, Article 35 obliges the bureau to make the corresponding adjustment. Cross-border relief runs through the mutual agreement procedure under Taiwan's income tax agreements, governed by the Ministry's Operational Directions of 2018 as amended in November 2020, with a three-year window from first notification. Notably, the Regulations contain no secondary adjustment mechanism — no deemed dividend or deemed loan follows a primary adjustment. Domestically the route is an application for recheck to the assessing bureau within 30 days, then administrative appeal, then the High Administrative Court and the Supreme Administrative Court.
Taiwan has not enacted the GloBE rules. There is no income inclusion rule, no undertaxed profits rule and no qualified domestic minimum top-up tax. What it has done instead is raise the corporate alternative minimum tax. In August 2024 the Ministry pre-announced a revised collection rate for the profit-seeking enterprise basic tax, lifting it from 12% to 15% for Taiwan entities of multinational groups meeting the global minimum tax revenue threshold, from the 2025 tax year, with all other enterprises remaining at 12%. The rate sits within the 12% to 15% band the Executive Yuan may set under Article 8 of the Income Basic Tax Act.
The distinction matters: this is not a QDMTT and will not be treated as one. It is a domestic rate rise designed to lift Taiwan effective rates towards 15% and shrink the top-up tax other jurisdictions collect on Taiwanese profits. Groups filing in 2026 for the 2025 year should confirm the final Executive Yuan order and model the AMT alongside, not instead of, their GloBE computations elsewhere. Taiwan has also not adopted Amount B: routine distributors remain subject to the ordinary comparable profits method with a full benchmarking study, and there is no guidance on whether Taiwan would accept an Amount B outcome applied by a counterparty jurisdiction.
Four priorities follow. First, test transaction by transaction. The Northern Area Bureau's May 2026 filing-season release names company-wide profitability testing as a leading error, and Article 7 gives the bureau the text to press it; aggregation needs a documented interlinkage argument.
Second, sweep for the unpriced. The same release targets three recurring omissions: affiliates using trademarks, patents or know-how without disclosure or compensation; management and technical support given to overseas group members without a service fee; and related-party receivables allowed to run long, or guarantees given, with no interest or fee recognised. These are disclosure failures before they are pricing failures, and undisclosed transactions open the fourth Article 34 gateway.
Third, treat the safe harbours as a filing decision, not a compliance strategy. Falling under NT$300 million or NT$200 million removes the obligation to produce a full report; it does not remove Article 43-1.
Fourth, plan the calendar backwards. A one-time year-end adjustment, available since fiscal year 2020 under the November 2019 ruling, works only if the participants agreed the pricing factors in advance, the adjustment is booked, the counterparty matches it, and the customs, VAT and withholding corrections are made in the prescribed windows. An APA must be applied for before the first covered year ends. Both are decisions taken during the year, not in May.
