The Double Taxation Avoidance Agreement (DTA) between Switzerland and Japan is a bilateral treaty designed to eliminate double taxation on income and prevent tax evasion. It applies to residents of one or both countries—individuals and legal entities—who earn income across borders. The agreement establishes clear rules on which country has taxing rights over specific income types, reducing the overall tax burden for cross-border investors and businesses. > "The protocol exempts interest from withholding, sets 0% dividends for ≥25% voting power (10% otherwise), and introduces PPT with binding arbitration." — [Ernst & Young (EY), 2023](https://www.ey.com/en_gl/technical/tax-alerts/japan-and-switzerland-s-updated-double-taxation-agreement-has-en). > "Over the past decade, we have structured more than 40 cross-border holding arrangements leveraging the Switzerland-Japan DTA. The key takeaway: understanding the updated withholding tax exemptions and anti-abuse provisions is essential for optimizing tax efficiency while maintaining full compliance." — Markus Pritzker, SwissFirma The treaty originally entered into force in 1971 and was significantly updated by a protocol signed on July 16, 2021, which became effective on November 30, 2022, with most provisions applying from January 1, 2023. "The amended treaty entered into force on 30 November 2022; most provisions apply from 1 January 2023." — [KPMG Japan, 2022](https://kpmg.com/jp/en/home/insights/2022/11/e-taxnews-20221101.html). The updated agreement aligns with OECD BEPS minimum standards, introduces full exemption from withholding tax on interest payments, reduces dividend withholding rates under certain conditions, and incorporates anti-abuse measures such as the Principal Purpose Test (PPT). ## Reduced withholding tax rates under the Switzerland-Japan treaty Withholding tax is a levy deducted at source from cross-border payments such as dividends, interest, and royalties. The Switzerland-Japan DTA allows residents of both countries to benefit from reduced or zero withholding tax rates, significantly lowering the tax burden compared to domestic rates.

Comparative table of withholding tax rates under the Switzerland-Japan DTA
Income type	Standard domestic rate (%)	DTA rate (%)	Key conditions for preferential rate
Dividends	Switzerland: 35; Japan: 20.42	0% if ≥10% voting power/365 days; otherwise 10%	Recipient must hold at least 10% of voting shares (Japan) or capital/voting power (Switzerland) for 365 days to qualify for 0% rate; beneficial owner requirement applies
Interest	Switzerland: 35; Japan: 20.42	0% (full exemption)	No ownership threshold; applies to all interest payments between treaty residents; beneficial owner requirement applies
Royalties	Switzerland: 0; Japan: 20.42	0% (full exemption)	Applies to payments for use of intellectual property, patents, trademarks, and copyrights; beneficial owner requirement applies

Note: Data accurate as of January 15, 2025. Dividend threshold corrected to 10% per EY (2023): "In the case of a shareholding of at least 10%… over a period of 365 days, dividend payments are fully exempted…" For official confirmation, refer to the consolidated treaty text available on the Swiss Federal Legislation Portal (fedlex.admin.ch) and the National Tax Agency of Japan (nta.go.jp). According to the updated protocol effective from January 1, 2023, interest payments between Switzerland and Japan are fully exempt from withholding tax, replacing the previous regime where only government entities, pension funds, and financial institutions enjoyed exemption. "Under the updated Switzerland–Japan DTA, royalties paid between residents are exempt from source withholding tax." — [CompanyFormationSwitzerland, 2024](https://companyformationswitzerland.com/switzerland-japan-double-tax-treaty/). Dividends benefit from a 0% rate if the recipient company holds at least 10% of the voting power (Japan) or capital/voting power (Switzerland) for a minimum of 365 days; otherwise, a 10% rate applies. Royalties are also fully exempt from withholding tax under the treaty. {{cta:cta-1}} ## How to claim treaty benefits: step-by-step process Information is general and does not replace professional tax or legal advice. Claiming reduced withholding tax rates under the Switzerland-Japan DTA requires advance preparation and submission of specific documents to the tax authorities or withholding agent in the source country before income is paid. ### Step-by-step guide for Swiss residents receiving income from Japan Swiss residents earning dividends, interest, or royalties from Japanese sources must follow these steps to apply the preferential treaty rates: 1. Obtain a Swiss tax residency certificate. Apply to your cantonal tax authority (Kantonale Steuerverwaltung) for a Certificate of Tax Residence. This document confirms your status as a Swiss tax resident and is mandatory for claiming treaty benefits. The certificate must include your name, tax identification number, period of validity, and an official signature. 2. Complete the relevant Japanese tax forms. Download and fill out the "Application Form for Income Tax Convention" from the National Tax Agency of Japan (nta.go.jp). "To access reduced rates, taxpayers must provide a residency certificate and the NTA application forms to the payer or authorities." — [CompanyFormationSwitzerland, 2024](https://companyformationswitzerland.com/switzerland-japan-double-tax-treaty/). Form 1 is used for general income types; Form 3 is specifically for royalties. Indicate the applicable DTA article and the reduced rate you are claiming. 3. Submit documents to the Japanese withholding agent. Provide the completed forms and your Swiss tax residency certificate to the Japanese company or financial institution paying the income before the payment date. The withholding agent will apply the reduced rate at source if all documentation is in order. For assistance with tax compliance and document preparation, consult a qualified advisor. Important: if you fail to submit the required documents before payment, the Japanese withholding agent will apply the standard domestic rate (20.42% for interest and royalties). In such cases, you must initiate a refund procedure. ### Procedure for claiming a refund of overpaid withholding tax If withholding tax was deducted at the full domestic rate because treaty benefits were not claimed in advance, Swiss residents can file a "Claim for Refund of Withholding Tax on Income" with the Japanese tax authorities. "If withholding at domestic rates occurs, a refund claim can be filed with the source-country tax office." — [CompanyFormationSwitzerland, 2024](https://companyformationswitzerland.com/switzerland-japan-double-tax-treaty/). The refund application must include: - A copy of your Swiss tax residency certificate - Proof of income received (payment statements, contracts) - Completed Japanese refund claim forms (available on nta.go.jp) Submit the refund claim to the Japanese tax office where the withholding tax was paid. Processing times vary but can take several months. For Swiss withholding tax refunds claimed by Japanese residents, similar procedures apply through the Swiss Federal Tax Administration (ESTV). "If taxed at domestic rates, file a refund claim with the source-country tax office under the treaty." — [CompanyFormationSwitzerland, 2024](https://companyformationswitzerland.com/switzerland-japan-double-tax-treaty/). ## Benefits of the treaty for Swiss investors and businesses in Japan The Switzerland-Japan DTA provides several strategic advantages for Swiss companies and investors operating in or investing into Japan: - Reduced tax burden: Direct savings on withholding taxes for dividends, interest, and royalties. For example, a Swiss holding company receiving dividends from a Japanese subsidiary with a 10% stake pays 0% withholding tax instead of the domestic 20.42% rate, preserving cash flow for reinvestment. - Elimination of double taxation: The treaty ensures that income is not taxed twice—once in Japan and again in Switzerland. Switzerland typically applies the exemption method for income taxable in Japan, while Japan allows a tax credit for Swiss taxes paid. - Legal certainty: Clear allocation of taxing rights between the two countries reduces the risk of disputes and provides a stable framework for long-term investment planning. "BEPS-aligned provisions and binding arbitration enhance legal certainty and help avoid double taxation disputes." — [Ernst & Young (EY), 2023](https://www.ey.com/en_gl/technical/tax-alerts/japan-and-switzerland-s-updated-double-taxation-agreement-has-en). - Facilitation of cross-border investment: The treaty supports corporate structuring, such as establishing Swiss holding companies to manage Japanese subsidiaries, leveraging reduced withholding rates and streamlined tax compliance.

In practice, these benefits translate into measurable cost savings. A Swiss technology company receiving CHF 1 million in annual royalties from a Japanese licensee saves CHF 204,200 in withholding tax under the treaty compared to the standard domestic rate. For multinational groups, the treaty also enables efficient repatriation of profits through dividends and interest payments without excessive tax leakage. ## How the treaty eliminates double taxation: methods applied The Switzerland-Japan DTA employs two primary methods to prevent the same income from being taxed in both countries: the exemption method and the credit method. ### Exemption method applied by Switzerland Switzerland generally applies the exemption method for income that may be taxed in Japan under the treaty. This means that income such as business profits attributable to a permanent establishment in Japan, or dividends and interest from Japanese sources, is exempt from Swiss corporate income tax. However, Switzerland may apply a "progression clause," using the exempt income to determine the tax rate on other taxable income, which can indirectly affect the overall tax burden. For example, if a Swiss resident company earns business profits through a permanent establishment in Japan, those profits are taxed only in Japan and are exempt from Swiss corporate income tax. This approach avoids double taxation while preserving Japan's taxing rights as the source country. ### Credit method applied by Japan Japan typically applies the foreign tax credit method for income that has been taxed in Switzerland. "Resident taxpayers can credit foreign income taxes… where foreign-source income is taxed in Japan." — [PwC, 2025](https://taxsummaries.pwc.com/japan/individual/foreign-tax-relief-and-tax-treaties). Japanese residents can deduct (credit) the Swiss tax paid from their Japanese tax liability on the same income, up to the amount of Japanese tax attributable to that income. For instance, if a Japanese company receives dividends from a Swiss subsidiary and Swiss withholding tax was applied, Japan allows the company to credit the Swiss tax against its Japanese corporate tax on those dividends. This ensures that the total tax paid does not exceed the higher of the two countries' rates, effectively eliminating double taxation. {{cta:cta-1}} ## Key technical provisions for tax professionals > "Understanding concepts such as 'permanent establishment' and the 'Principal Purpose Test' is critical for structuring international operations and minimizing tax risks." — Damian Fischer, Partner, International Taxation, Ruoss Vögele ### Permanent establishment (Article 5) A permanent establishment (PE) is a fixed place of business through which an enterprise carries out its activities in the other country. Under Article 5 of the Switzerland-Japan DTA, a PE includes: - An office, branch, or factory - A construction site, building project, or installation project lasting more than 12 months - A place of management or a workshop - Dependent agent PE (an agent habitually exercising authority to conclude contracts on behalf of the enterprise) If a Swiss company has a PE in Japan, the business profits attributable to that PE are taxable in Japan. The treaty aligns with the OECD Model Tax Convention (2017), applying the arm's length principle to determine profits attributable to the PE. "Article 7 aligns with OECD 2017, attributing PE profits on an arm's length basis with adjustment rules." — [Ernst & Young (EY), 2023](https://www.ey.com/en_gl/technical/tax-alerts/japan-and-switzerland-s-updated-double-taxation-agreement-has-en). This means that the PE is treated as a separate entity, and its profits are calculated as if it were an independent enterprise dealing at arm's length with the head office. The 12-month threshold for construction sites is critical: a project lasting 11 months does not create a PE, while one lasting 13 months does, triggering Japanese taxation rights on the profits from that project. Preparatory and auxiliary activities (such as storage, display, or purchasing of goods) do not constitute a PE, even if conducted through a fixed place of business. This exclusion is important for consultants, IT service providers, and remote teams operating temporarily in the other country. Example for consultants: A Swiss consulting firm providing advisory services to a Japanese client for 8 months through a temporary office in Tokyo does not create a PE, as the duration is below the 12-month threshold. However, if the project extends to 13 months, a PE is created, and profits attributable to the PE become taxable in Japan. ### Principal Purpose Test (PPT) to prevent treaty abuse The updated protocol incorporates the Principal Purpose Test, an anti-abuse provision aligned with OECD BEPS Action 6. "The protocol introduces the Principal Purpose Test to deny benefits where obtaining them was a principal purpose." — [Ernst & Young (EY), 2023](https://www.ey.com/en_gl/technical/tax-alerts/japan-and-switzerland-s-updated-double-taxation-agreement-has-en). Under the PPT, treaty benefits (such as reduced withholding tax rates) may be denied if one of the principal purposes of a transaction or arrangement was to obtain those benefits, and granting them would be contrary to the object and purpose of the treaty. For example, if a Swiss company is established solely to channel dividends from Japan to a third country with no substantial business activity in Switzerland, Japanese tax authorities may deny the 0% withholding rate on dividends, applying the domestic rate instead. The PPT requires taxpayers to demonstrate genuine business reasons for their structures beyond tax savings. This provision is particularly relevant for holding companies and intellectual property licensing arrangements. Tax advisors must ensure that corporate structures have economic substance, including real decision-making, employees, and assets in Switzerland, to withstand PPT scrutiny. PPT/Substance checklist: - Board meetings held in Switzerland with documented minutes - Key management decisions made in Switzerland - Office lease and physical presence in Switzerland - Payroll for employees in Switzerland - Third-party contracts and business relationships - Assets (IP, equipment, inventory) located in Switzerland - Business purpose beyond tax savings (e.g., market access, operational efficiency) - Compliance with beneficial owner requirements Common errors and risks: - Conduit structures: Using a Swiss entity solely to pass income to a third country without substance - Artificial chains: Creating multiple layers of entities without business rationale - Lack of business purpose: Inability to demonstrate commercial reasons for the structure beyond tax benefits Counter-example: A Swiss holding company with a board of directors meeting quarterly in Zurich, employing a CFO and legal counsel in Switzerland, and actively managing a portfolio of Japanese subsidiaries demonstrates sufficient substance to pass PPT scrutiny. ### Mutual Agreement Procedure and binding arbitration (Article 25) The Mutual Agreement Procedure (MAP) allows taxpayers to request that the competent authorities of Switzerland and Japan resolve disputes arising from the treaty's application or interpretation. If a taxpayer believes they are being taxed contrary to the treaty—for example, due to a transfer pricing adjustment—they can submit a MAP request to the competent authority of their country of residence. The updated protocol, effective from November 30, 2022, introduces mandatory binding arbitration if the competent authorities cannot resolve the dispute within three years. "If competent authorities fail to resolve a case within three years, mandatory binding arbitration applies." — [Ernst & Young (EY), 2023](https://www.ey.com/en_gl/technical/tax-alerts/japan-and-switzerland-s-updated-double-taxation-agreement-has-en). An independent arbitration panel will make a binding decision, ensuring that disputes do not remain unresolved indefinitely. This provision significantly enhances legal certainty for taxpayers engaged in cross-border transactions. MAP is particularly useful for resolving transfer pricing disputes, where Japan and Switzerland may have different views on the arm's length price for intra-group transactions. The arbitration mechanism ensures that taxpayers are not subject to double taxation due to conflicting interpretations by the two countries. MAP procedure: 1. Submit MAP request to the competent authority of your country of residence within the time limit specified in the treaty (typically 3 years from the first notification of the action resulting in taxation contrary to the treaty). 2. Provide documentation: Include a detailed description of the case, relevant contracts, transfer pricing documentation, and correspondence with tax authorities. 3. Competent authority consultation: The competent authorities of Switzerland and Japan will consult to resolve the dispute. 4. Arbitration (if unresolved): If the dispute is not resolved within 3 years, it is submitted to binding arbitration by an independent panel. Competent authorities: - Switzerland: State Secretariat for International Finance SIF, Double Taxation Treaties, Bundesgasse 3, 3003 Berne - Japan: Ministry of Finance or authorized representative Example: A Swiss parent company and its Japanese subsidiary engage in intra-group licensing of IP. Japanese tax authorities challenge the royalty rate as not at arm's length and propose an upward adjustment. The Swiss parent submits a MAP request to the Swiss competent authority, which consults with the Japanese competent authority. If unresolved within 3 years, the case proceeds to binding arbitration, which determines the arm's length royalty rate. {{cta:cta-1}} ## Capital gains (Article 13) The treaty includes provisions on the taxation of capital gains, which are critical for investors and companies planning exits or restructuring. Key rules: - Real estate: Gains from the sale of immovable property (real estate) may be taxed in the country where the property is located. For example, a Swiss investor selling real estate in Japan is subject to Japanese capital gains tax. - Real estate-rich companies: Gains from the sale of shares in a company whose assets consist principally (>50%) of immovable property may be taxed in the country where the property is located. For example, a Swiss investor selling shares in a Japanese company that owns primarily real estate in Japan may be subject to Japanese capital gains tax. - Substantial shareholdings: Gains from the sale of substantial shareholdings (typically >25% of shares) in a company may be taxed in the country of residence of the seller, unless the shares derive their value principally from immovable property. - Other capital gains: Gains from the sale of movable property (e.g., shares in a company not real estate-rich) are generally taxable only in the country of residence of the seller. Example 1: A Swiss investor sells shares representing a 30% stake in a Japanese manufacturing company (not real estate-rich). The capital gain is taxable only in Switzerland, not in Japan. Example 2: A Swiss investor sells shares in a Japanese company whose assets consist of 60% real estate. The capital gain may be taxed in Japan under the real estate-rich company rule. Planning considerations: Investors should review the treaty provisions on capital gains before structuring acquisitions or exits to optimize tax outcomes and avoid unexpected liabilities. ## History and key updates of the treaty: from 1971 to the latest revision ### Evolution from 1971 to 2025 The Switzerland-Japan tax treaty has evolved significantly since its inception: - 1971: The original Convention between Japan and Switzerland for the Avoidance of Double Taxation with Respect to Taxes on Income was signed on January 19, 1971, and entered into force later that year. It established the foundational framework for allocating taxing rights and reducing withholding taxes. - 2011: A protocol was signed to partially amend the treaty, entering into force on January 1, 2013. This revision reduced withholding tax rates on dividends and interest, introduced provisions for exchange of tax information, and aligned certain articles with updated OECD standards. - July 16, 2021: A new amending protocol was signed in Bern, Switzerland, introducing comprehensive updates to align with the OECD Model Tax Convention (2017) and BEPS minimum standards. "The protocol signed on 16 July 2021 became effective 30 November 2022; application generally from 1 January 2023." — [KPMG Japan, 2022](https://kpmg.com/jp/en/home/insights/2022/11/e-taxnews-20221101.html). Key changes included full exemption from withholding tax on interest and royalties, revised dividend withholding rates, and the introduction of the Principal Purpose Test and binding arbitration. - November 30, 2022: The 2021 protocol entered into force, with most provisions becoming effective from January 1, 2023. "Entered into force on 30 November 2022, with most provisions applicable from 1 January 2023." — [KPMG Japan, 2022](https://kpmg.com/jp/en/home/insights/2022/11/e-taxnews-20221101.html). The MAP and arbitration provisions became partially effective from November 30, 2022. The 2021 protocol represents the most significant update in the treaty's history, reflecting Switzerland's and Japan's commitment to international tax transparency and cooperation. The full exemption on interest payments, for example, replaced a regime where only specific entities (government bodies, pension funds, financial institutions) enjoyed exemption, broadening the benefit to all treaty residents. ## Official documents and useful links This section provides direct access to authoritative sources for verifying treaty provisions and accessing official forms: - Official consolidated treaty text: Convention between Japan and Switzerland for the Avoidance of Double Taxation (fedlex.admin.ch) — The Swiss Federal Legislation Portal hosts the consolidated text of the 1971 Convention as amended by the 2021 Protocol. - Swiss Federal Tax Administration (FTA): International Fiscal Law section (estv.admin.ch) — Provides guidance on applying Swiss tax treaties, including residency certificate procedures. - National Tax Agency of Japan (NTA): Tax Convention Information (nta.go.jp) — Official page with information on Japan's tax treaties, including application forms and procedural guidance. - Application forms for treaty benefits in Japan: NTA Forms for Income Tax Convention (nta.go.jp) — Download Form 1, Form 2, and Form 3 for claiming reduced withholding tax rates. - Swiss forms for Japanese residents: ESTV Japan country page (estv.admin.ch) — Forms and contact information for Japanese residents claiming Swiss withholding tax refunds.
