Double Taxation Avoidance and Transfer Pricing for International Investors in Hungary

Introduction

Hungary’s 9% corporate income tax rate — the lowest in the European Union — has been a cornerstone of its strategy to attract foreign direct investment. However, the Hungarian tax environment is considerably more complex than the headline rate suggests. International investors must navigate an extensive network of double taxation avoidance treaties (“DTAs”), comply with increasingly rigorous transfer pricing documentation requirements, and, since 2024, contend with the implications of the OECD/G20 Pillar Two global minimum tax framework. This article provides a comprehensive overview of these interrelated topics as they apply to international investors operating in or through Hungary in 2026.

Hungary’s Double Taxation Treaty Network

Overview

Hungary has concluded DTAs with more than 80 countries, covering virtually all major trading partners and investment-origin jurisdictions. The treaties broadly follow the OECD Model Tax Convention, with certain provisions adapted to reflect Hungary’s specific fiscal policy objectives. Notable DTAs include those with the United States, the United Kingdom, Germany, China, Japan, South Korea, the United Arab Emirates, and Singapore.

The treaties allocate taxing rights between Hungary and the treaty partner state and provide mechanisms to eliminate or reduce double taxation of cross-border income, including dividends, interest, royalties, capital gains, and employment income.

Application of DTAs

To benefit from a DTA, the taxpayer must:

1. Be a tax resident of one of the contracting states.
2. Be the beneficial owner of the income in question.
3. Apply for reduced withholding tax rates (where applicable) through the appropriate domestic procedure — in Hungary, this is typically done through a self-certification procedure at the time of payment, with verification by the National Tax and Customs Administration (Nemzeti Adó- és Vámhivatal, “NAV”).

Hungarian domestic law, under Act LXXXI of 1996 on Corporate and Dividend Tax (1996. évi LXXXI. törvény a társasági adóról és az osztalékadóról, “Tao tv.”), generally provides for a 0% withholding tax on dividends paid by a Hungarian company to a foreign corporate shareholder, and 0% on interest and royalties paid to EU/EEA-resident companies (subject to the Interest and Royalties Directive conditions). Where the domestic rate is already 0%, the DTA rate is effectively moot, but the treaty may provide additional protections against changes in domestic law and may affect the tax treatment in the recipient’s home jurisdiction.

The OECD Multilateral Instrument (MLI)

Hungary has ratified the OECD Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (the “MLI”), which modifies many of its bilateral DTAs simultaneously. The MLI introduces, among other provisions:

• A principal purpose test (PPT) to deny treaty benefits where one of the principal purposes of an arrangement is to obtain such benefits (anti-treaty-shopping provision).
• Modified permanent establishment (PE) rules, including the anti-fragmentation rule and the dependent agent PE rule.
• Changes to the mutual agreement procedure (MAP) to improve dispute resolution.

Investors should verify whether the specific DTA applicable to their situation has been modified by the MLI, as not all of Hungary’s DTA partners have ratified the MLI or have adopted the same provisions.

The 9% Corporate Income Tax Rate

Hungary’s headline CIT rate of 9% applies to the worldwide income of Hungarian tax resident companies and to the Hungarian-source income of non-resident companies operating through a permanent establishment in Hungary. The rate has been in force since 1 January 2017, following a reduction from the previous 10%/19% two-tier system.

Key features of the Hungarian CIT regime include:

• No distinction between distributed and retained profits: the 9% rate applies uniformly.
• Participation exemption: Dividends received from qualifying subsidiaries (at least 10% shareholding held for at least one year) are exempt from CIT. Capital gains on the disposal of qualifying participations may also be exempt under a reported participation exemption regime, subject to strict formal requirements (advance notification to NAV).
• R&D super-deduction: Qualifying research and development costs benefit from an enhanced deduction (up to 200% of eligible costs).
• IP box regime: Income derived from qualifying intellectual property may be taxed at an effective rate as low as 4.5%, calculated by applying a modified nexus approach consistent with the OECD’s BEPS Action 5 recommendations.

Pillar Two: The Global Minimum Tax

Overview

The OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (“BEPS”) adopted the Pillar Two rules (also known as the Global Anti-Base Erosion or “GloBE” rules) to establish a global minimum effective tax rate of 15% for large multinational enterprise (MNE) groups with consolidated revenue of at least EUR 750 million per year. Hungary transposed Pillar Two into domestic law through amendments to the Tao tv. effective from 31 December 2023 (in line with the EU Minimum Tax Directive 2022/2523).

Impact on Hungary

For MNE groups within scope, Hungary’s 9% headline CIT rate is below the 15% minimum. This means that if a Hungarian subsidiary’s effective tax rate (ETR) — calculated under the GloBE rules — is below 15%, a top-up tax will be imposed to bring the ETR up to 15%.

Hungary has adopted a Qualified Domestic Minimum Top-Up Tax (“QDMTT”), which allows Hungary to collect the top-up tax itself rather than ceding the taxing right to the parent jurisdiction under the Income Inclusion Rule (IIR). The QDMTT is calculated in accordance with the GloBE rules and is payable by the Hungarian constituent entity.

Practical Implications

• MNE groups with Hungarian operations must assess whether their Hungarian entities are subject to top-up tax. The assessment requires a detailed computation of the GloBE effective tax rate, taking into account adjustments such as deferred tax, temporary differences, and the substance-based income exclusion (SBIE).
• The SBIE allows a carve-out for income attributable to substantive economic activity in Hungary, calculated as a percentage of eligible payroll costs and tangible asset carrying values. MNE groups with significant employees, manufacturing facilities, or other tangible assets in Hungary may benefit from a larger SBIE, reducing or eliminating the top-up tax.
• Smaller companies and groups below the EUR 750 million revenue threshold are not affected by Pillar Two and continue to benefit from the full 9% rate.
• Even for in-scope MNEs, Hungary’s effective rate is often brought close to or above 15% by the local business tax (helyi iparűzési adó, “HIPA”), at up to 2%, and the innovation contribution (innovációs járulék), at 0.3% of net revenue, which are treated as covered taxes under the GloBE rules. Additionally, the energy crisis special tax and sector-specific surtaxes may further increase the effective burden.

Transfer Pricing: Documentation and Compliance

Legal Framework

Transfer pricing in Hungary is governed by:

• Section 18 of the Tao tv., which requires transactions between related parties (kapcsolt vállalkozások) to be conducted at arm’s length and provides for adjustments where prices deviate from arm’s length.
• Government Decree 32/2017 (X. 18.) on Transfer Pricing Documentation (32/2017. (X. 18.) NGM rendelet a szokásos piaci ár meghatározásával összefüggő nyilvántartási kötelezettségről), which prescribes the content and format of transfer pricing documentation.
• The OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (2022 edition), which Hungarian law explicitly references as an interpretive source.

Documentation Requirements

Hungarian entities that engage in related-party transactions are required to maintain transfer pricing documentation in the form of a master file (fődokumentum) and a local file (helyi dokumentum), consistent with the OECD’s three-tiered documentation approach. The documentation must be prepared by the filing deadline for the CIT return for the relevant fiscal year and must be available for inspection by NAV upon request.

The documentation must include:

• A description of the related-party transaction(s).
• A functional analysis identifying the functions performed, assets used, and risks assumed by each party.
• A comparability analysis identifying comparable uncontrolled transactions or companies.
• The transfer pricing method applied (comparable uncontrolled price, resale price, cost plus, transactional net margin method, or profit split method).
• The arm’s length range and the position of the tested transaction within it.

Exemptions

Certain transactions are exempt from the documentation requirement, including:

• Transactions between two Hungarian tax resident entities that are subject to the same tax rate and neither is exempt from tax or benefits from a tax holiday.
• Transactions below a de minimis threshold (currently, transactions with an aggregate value below HUF 50 million with a single related party in a given tax year are exempt from the local file requirement, although not from the arm’s length pricing obligation itself).

NAV Scrutiny in 2026

NAV has identified transfer pricing as a priority audit focus for 2026. Areas of particular interest include:

• Management fees and service charges between Hungarian subsidiaries and foreign parent companies — NAV frequently challenges the arm’s length nature of these charges.
• Intra-group financing — loans and guarantees between related parties, with particular attention to interest rates and the substance of the lending entity.
• Restructuring transactions — the transfer of functions, assets, or risks from Hungarian entities to related foreign entities, which may trigger exit taxation and transfer pricing adjustments.
• Low-value-adding services — application of the simplified 5% mark-up approach, where NAV may question whether the services truly qualify as “low-value-adding.”

Companies are strongly advised to review and update their transfer pricing documentation proactively, ensuring it reflects current-year transactions and market conditions.

Hungarian Holding Structures

Advantages

Hungary’s combination of a low CIT rate, participation exemption, extensive DTA network, and EU membership makes it an attractive jurisdiction for holding company structures. A Hungarian holding company (typically a Kft. or Zrt.) can serve as an intermediate holding vehicle for investments in Central and Eastern Europe, benefiting from:

• Dividend exemption on qualifying participations.
• Capital gains exemption on the disposal of qualifying participations (subject to the reported participation regime).
• Interest and royalties paid to EU/EEA recipients without withholding tax.
• Access to EU directives: the Parent-Subsidiary Directive, the Interest and Royalties Directive, and the Merger Directive.
• Low administrative costs relative to other EU holding jurisdictions.

Substance Requirements

Under both the MLI’s principal purpose test and the EU Anti-Tax Avoidance Directive (ATAD) provisions transposed into the Tao tv., holding structures must demonstrate genuine economic substance in Hungary to resist challenges from tax authorities in other jurisdictions. Substance indicators include:

• A physical office in Hungary.
• Qualified local management (directors with decision-making authority who are resident in Hungary).
• Local employees performing substantive functions.
• Board meetings held in Hungary with documented minutes.

So-called “letterbox companies” with no genuine Hungarian substance face an increasing risk of denial of treaty benefits by counterpart jurisdictions and potential reclassification by NAV under domestic anti-avoidance rules.

Advance Pricing Agreements (APAs)

Hungarian taxpayers may apply to NAV for an Advance Pricing Agreement under Section 132/B of Act CL of 2017 on the Rules of Taxation (2017. évi CL. törvény az adózás rendjéről, “Art.”). An APA provides certainty by confirming in advance the arm’s length pricing methodology for specified related-party transactions.

APAs may be:

• Unilateral: between the taxpayer and NAV.
• Bilateral or multilateral: between NAV and the tax authorities of the counterpart jurisdiction(s), providing certainty against double taxation.

The APA application fee is between HUF 2 million and HUF 5 million, depending on the type and scope. The processing time for a unilateral APA is approximately 120 days; bilateral APAs may take significantly longer due to the need for inter-authority negotiations.

Conclusion

Hungary remains a highly competitive jurisdiction for international investors, but the tax landscape is evolving rapidly. The interaction between Hungary’s low CIT rate, the Pillar Two global minimum tax, and increasingly stringent transfer pricing enforcement requires careful planning and documentation. Investors are well advised to engage experienced Hungarian tax counsel to ensure that their structures are compliant, substantive, and optimized for the current regulatory environment.
