Each Member State sets its ordinary company-tax rules, while EU law adds targeted rules for cross-border activity and a separate 15% minimum effective tax regime for qualifying large groups. A company operating in several Member States may therefore face several national tax systems at once.
Who sets company tax rules in the EU?
Ordinary corporate income tax is national
Member States decide how their ordinary business-tax systems work: who is taxable, which profits are included, what deductions or incentives apply, and what rates are charged. The European Commission summarizes the division of responsibility this way: “EU countries generally hold the competence to design their own business tax systems and decide who, what and when to tax, at what rate, and how.” The Commission’s business-taxation overview describes the EU’s role and the areas where common rules apply.

For a company operating across borders, the starting point is usually the country where an entity is tax-resident, along with any other country where it has a taxable presence. The applicable national rules determine how that presence is taxed. The EU’s Company tax in the EU guide provides country-by-country navigation and notes that national rules differ. For a broader overview, the Commission’s business-taxation page points to its Taxes in Europe Database; confirm liability and filing questions with the relevant national tax authority.

The EU has adopted common rules in defined areas, especially cross-border situations and measures to address tax avoidance. These rules do not amount to one consolidated EU corporate tax code, and they do not replace the national rules that determine ordinary company tax.

What varies between Member States?
A headline statutory rate is only one part of a company’s tax position. The tax base—how taxable profit is calculated—can differ, as can the treatment of deductions, losses, incentives, cross-border payments, reorganisations, and filing requirements. The rules applicable to a particular group also depend on whether it falls within the separate Pillar Two regime.
When comparing countries, assess the following together rather than ranking them by headline rate alone:
Rank #2
| What to compare | Why it matters |
|---|---|
| Statutory corporate income tax rate and tax base | The rate applies to taxable profit as defined by national rules; a rate by itself does not show how much income is taxable. |
| Deductions, incentives, and loss treatment | These can affect the amount and timing of taxable profit. |
| Cross-border payments and reorganisations | National rules interact with targeted EU rules and, where relevant, treaty arrangements. |
| Pillar Two scope and top-up taxes | A group covered by the minimum-tax regime may have additional jurisdictional calculations and tax obligations. |
| Filing and reporting duties | A group may need to meet separate national obligations as well as applicable group-level reporting requirements. |
For country-specific rates, tax-base details, incentives, or deadlines, consult dated information from the relevant national tax authority. The Your Europe company-tax guide is a starting point for locating national information, not a substitute for checking the rules that apply to a particular company.

What common EU rules affect cross-border companies?
Anti-Tax Avoidance Directive
The Anti-Tax Avoidance Directive establishes minimum safeguards in five areas: limits on interest deductions, exit taxation, controlled foreign company rules, a general anti-abuse rule, and hybrid mismatches. According to the Commission’s overview of the Directive, the measures applied from 1 January 2020, except for the hybrid mismatch rule, which has applied since 1 January 2022.
Other targeted cross-border rules
Other EU directives address particular transactions and relationships: the Parent-Subsidiary Directive concerns group distributions; the Merger Directive addresses cross-border reorganisations; and the Interest & Royalty Directive covers qualifying intra-group payments. The EU also provides a dispute-resolution mechanism for treaty disputes. These rules address specific issues; they do not harmonise every aspect of corporate taxation. The Commission’s business-taxation overview describes these EU-level areas.
How does the 15% minimum tax work?
It is an effective minimum for qualifying groups—not the ordinary tax rate
The EU implemented the Pillar Two framework through Council Directive (EU) 2022/2523. The Commission says it applies to large multinational and large-scale domestic groups with combined annual financial revenue above €750 million and an EU presence. Member States were to transpose the Directive by 31 December 2023, with application to fiscal years starting in January 2024, according to the Commission’s Minimum Corporate Taxation page.
The 15% figure is a minimum effective tax rate under Pillar Two, not a single statutory corporate income tax rate imposed on all EU companies. The regime calculates an effective rate separately for each jurisdiction by comparing covered taxes paid by entities there with their qualifying income. If the jurisdictional effective rate is below 15%, top-up tax mechanisms may apply. The Directive and the Commission’s 31 December 2023 announcement set out the minimum-tax framework.
How top-up tax is collected
The framework provides for an Income Inclusion Rule (IIR), an Undertaxed Profits Rule (UTPR), and a qualified domestic minimum top-up tax (QDMTT). At a high level, the IIR and UTPR can apply when a group has a low-taxed entity in a country that does not impose the global minimum tax. The rules allocate any top-up through mechanisms that depend on ownership and, for the UTPR, a formula involving employees and assets. The Directive also includes exclusions, including de minimis and substance-based exclusions, and special treatment for certain income such as international shipping. The detailed calculation depends on the group’s circumstances and the Directive’s rules.

Reporting and information exchange
DAC9 extends cooperation and information exchange between tax authorities for Pillar Two information returns. The Council stated that Member States had to adopt and publish measures implementing DAC9 by 31 December 2025. That deadline is set out in the Council’s 14 April 2025 notice.

No. BEFIT—Business in Europe: Framework for Income Taxation—is a Commission proposal adopted on 12 September 2023, not an operative common tax base. It would introduce common rules for computing the tax bases of eligible group members using financial accounting statements, then allocate results among them. Member States could adjust allocated tax bases under national rules and apply their own corporate tax rates. The proposal requires unanimous agreement in the Council before it can become law. See the Commission’s BEFIT proposal page.
Quick Recap
What should a large group do when comparing countries?
- Map where tax obligations may arise. Identify each entity’s tax residence and other locations where it may have a taxable presence, then check the applicable national rules.
- Compare the full tax calculation. Review statutory rates alongside tax bases, deductions, incentives, and loss treatment; do not use the headline rate as a proxy for the group’s effective burden.
- Check cross-border rules. Assess relevant EU directives, national rules, and treaty issues for distributions, payments, reorganisations, and disputes.
- Test Pillar Two scope. Determine whether the group meets the regime’s threshold and EU-presence conditions, then assess jurisdictional effective rates and possible top-up mechanisms.
- Verify filings and reporting locally. Confirm current deadlines and obligations with the national authorities concerned, including any applicable Pillar Two reporting requirements.
