Beyond the Tax Rate: Industrial Substance and the New Economics of CEE Automotive Manufacturing

How Hungary’s position at the intersection of Pillar Two, Decree 45/2025, and the EV transition became the live test case for CEE manufacturing investment

BMW builds its most advanced EV plant in Debrecen. BYD launches European production in Szeged. And every multinational above €750m in group revenue now faces a minimum 15% global tax — at a 9% local rate. Can genuine industrial substance protect a manufacturing location’s economics when the global tax architecture is specifically designed to neutralise headline rate advantages? Hungary has become the live test case for that question — but the answer has implications for every CEE manufacturing hub, and for every multinational group with European production exposure.

WHY THIS MATTERS RIGHT NOW Two regulatory developments create immediate urgency. Hungary’s new Transfer Pricing Decree (Decree 45/2025, effective 1 January 2026) significantly tightens documentation requirements. And OECD Pillar Two, the 15% global minimum tax, is now in effect across the EU. With Hungary’s 9% corporate rate, every group above €750m in consolidated revenue faces a top-up exposure. Critically, transfer pricing methodology directly determines how much profit is allocated to Hungary — and therefore directly drives the Pillar Two liability.

The mechanism that determines exposure

Pillar Two was designed to prevent profit shifting — the allocation of income to low-tax jurisdictions that lack genuine economic activity. Hungary’s automotive sector is the opposite of that profile. It has plant, equipment, payroll, engineering capability, and in Debrecen, a production facility setting the global standard for automotive manufacturing.

The protection mechanism is the Substance-Based Income Exclusion (SBIE): a carve-out that excludes a percentage of tangible fixed assets and eligible payroll from top-up calculations. For a capital-intensive OEM-tier manufacturer, the numbers look like this:

Scenario A: OEM-tier manufacturer (€400m assets | €80m payroll | €55m GloBE income)

SBIE rates (tangible / payroll)	7.4% / 9.4%	6.6% / 8.2%	5.0% / 5.0%
Total SBIE exclusion	€37.1m	€33.0m	€24.0m
Post-SBIE ETR	48.9%	39.8%	28.2%
Top-up tax	Nil	Nil	Nil

For Tier 2 suppliers with lighter asset bases, protection holds but the margin narrows to 2.5 percentage points above the 15% floor by 2033 — and does not withstand restructuring or asset depreciation without replacement. Full modelling in the white paper.

For genuinely capital-intensive operations, protection holds across all three time horizons. What this table does not show — but the full white paper models — is that the SBIE declines every year, with the pace of reduction steepening sharply from 2029. Groups should be modelling that inflection now, not when it arrives.

The advantage most groups have not modelled

Hungary’s Pillar Two position has a second layer that is materially underweighted in most modelling. Hungary’s covered taxes definition includes not just corporate income tax but the local business tax and the innovation contribution — levied on a broad base that for manufacturing entities frequently exceeds the CIT base. For many automotive manufacturers in Hungary, when covered taxes are properly aggregated, the jurisdictional effective rate already approaches or exceeds 15% before the SBIE is even applied.

This outcome depends entirely on accurate profit allocation. Transfer pricing methodology determines how much GloBE income is allocated to Hungary. If the entity is characterised as more routine than its actual functions warrant, GloBE income is suppressed — and the covered taxes stack that appeared adequate suddenly is not.

The compliance event that changes the picture

Decree 45/2025 tightens Hungary’s transfer pricing documentation framework in ways that go beyond compliance. Three provisions matter most:

Local benchmarking: centrally prepared pan-European studies are only accepted if they demonstrably comply with Hungarian comparability criteria
Mandatory DEMPE analysis: detailed documentation of where value in automotive development and engineering is actually being created
Benefit test for intra-group services: management fees disallowed entirely — not merely adjusted — when evidence of genuine benefit cannot be produced

For many Hungarian automotive entities, this creates a structural tension. The standard model — limited-risk contract manufacturer, cost-plus basis, centrally prepared benchmarking — was designed for a simpler operating reality. Many of these entities now perform procurement, quality engineering, process development, and supplier management that was never contemplated in their original intercompany frameworks. Their documentation describes a company from twenty years ago. Their operations are something considerably more substantial.

Two stories, one country

Hungary’s automotive sector in 2026 is bifurcating. BMW, BYD, Audi, and Mercedes-Benz are expanding — with facilities that represent their most forward-looking production capabilities. For well-documented, capital-intensive operations, the Pillar Two mechanics are manageable and the regulatory environment is navigable.

At the same time, the European components sector is contracting through closures rather than restructuring, a pattern that is structurally different from previous downturns. Lighter-asset Tier 2 suppliers face narrowing SBIE margins, rising labour costs, and demand pressure simultaneously. For this tier, structural headwinds are not a problem that cost competitiveness alone can resolve.

It is not one story. It is two, running simultaneously, in the same country. The paper that pretends otherwise is not describing Hungary as it actually exists in 2026.

How Moore supports automotive groups in CEE

Moore Global brings together local expertise across Central and Eastern Europe with a globally coordinated professional services network. For automotive and manufacturing-intensive groups, we work across four areas:

Transfer Pricing Strategy & Documentation — DEMPE analysis, local file preparation aligned with Decree 45/2025, NAV audit defence
Pillar Two Modelling — SBIE optimisation, covered taxes stacking, multi-year exposure modelling through the 2029 and 2033 inflection points
Entity Function Assessment — characterisation reviews where operational reality has evolved beyond original intercompany frameworks
CEE Network Coordination — integrated support across Hungary, Poland, Slovakia, Romania and beyond

Moore will be at Portfolio Automotive Industry 2026 in Budapest, 26–27 March. Meet our CEE automotive tax team in person. Find out more about the event and our presence
