There is no single EU corporate tax rate or fully harmonised system for taxing company profits. Member States set their ordinary company-tax rules, while EU law adds targeted rules for cross-border situations and a 15% minimum effective-tax regime for qualifying large groups.
Who sets ordinary company tax rules in the EU?
Ordinary corporate income tax is primarily national. Member States decide how their business tax systems work, including who and what is taxed, at what rate and under which rules. The European Commission describes this as a national competence; EU rules apply in defined areas rather than replacing each country’s system. (European Commission: Business Taxation)
For a company operating in more than one country, the starting point is the rules in each country where it is tax-resident or has a taxable presence. National systems can differ in both their headline rates and the way they determine taxable profit. The EU’s Your Europe company-tax guide provides country-by-country navigation; the Commission’s Taxes in Europe Database is another starting point for broader tax information. For liability, filing and current rates, confirm details with the relevant national tax authority.
What should companies compare across Member States?
A headline corporate tax rate alone cannot show a group’s actual tax burden. A useful comparison considers the rules that determine taxable profit, cross-border obligations and whether the group is subject to the EU minimum-tax regime.
#1 Best Overall
- Statutory rate and tax base: compare the rate with the rules used to calculate taxable profit.
- Deductions, incentives and losses: examine how each country treats these when arriving at taxable income.
- Cross-border payments and reorganisations: check the applicable rules for group distributions, intra-group payments and restructurings.
- Pillar Two exposure: establish whether the group is in scope and whether any jurisdictional top-up tax may apply.
- Filing and reporting: identify obligations in each relevant country, including information reporting for groups within the minimum-tax framework.
There is no single current ordinary corporate rate that can be applied across the EU. Rates, tax bases and filing rules are country-specific and can change.
Which common EU rules affect cross-border company taxation?
EU directives establish common rules in specific areas; they do not create one consolidated corporate tax code. For example, 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 certain treaty disputes. (European Commission: Business Taxation)

Anti-Tax Avoidance Directive
The Anti-Tax Avoidance Directive sets minimum safeguards against common forms of aggressive tax planning. Its measures address five areas:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Limits on interest deductions
- Exit taxation
- Controlled foreign companies
- A general anti-abuse rule
- Hybrid mismatches
The European Commission says the measures applied from 1 January 2020, except the hybrid-mismatch rule, which applied from 1 January 2022. These are common safeguards implemented through national systems, not a replacement for national corporate tax rules. (European Commission: Anti-Tax Avoidance Directive)
What is the EU’s 15% minimum tax?
The EU’s Pillar Two rules create a minimum effective-tax mechanism for qualifying large groups. They do not set a 15% ordinary statutory corporate tax rate for every company. Under the framework, the effective tax rate is calculated separately for each jurisdiction by comparing covered taxes paid there with qualifying income. If a jurisdiction’s effective rate is below 15%, a top-up tax may apply under the rules. (Council Directive (EU) 2022/2523; European Commission, 31 December 2023)
Which groups are covered?
The European Commission describes the scope as large multinational and large-scale domestic groups with combined annual financial revenue above €750 million and an EU presence. This threshold concerns the group’s combined annual financial revenue, not an individual subsidiary’s revenue. The rules also provide exclusions, including de minimis and substance-based exclusions, and special treatment for some income, such as international shipping. (European Commission: Minimum Corporate Taxation)
How can top-up tax be collected?
The EU Directive provides three mechanisms. Their interaction depends on where the group entities are located, ownership and, for one mechanism, a formula involving employees and assets.
| Mechanism | Role in the framework |
|---|---|
| Qualified domestic minimum top-up tax (QDMTT) | A jurisdiction may impose a domestic top-up tax where the relevant local effective tax rate is below the minimum. |
| Income Inclusion Rule (IIR) | Can require a parent entity to account for top-up tax on low-taxed group entities. |
| Undertaxed Profits Rule (UTPR) | Can apply as a backstop where top-up tax is not collected under the IIR; its allocation uses a formula involving employees and assets. |
The Commission explains that the IIR and UTPR can apply where a low-taxed group entity is in a country that does not impose the global minimum tax. The Directive sets out the detailed calculations, ordering rules and conditions; a group’s result cannot be inferred from a national headline rate alone.

When did the rules take effect, and what is DAC9?
Under the Directive, Member States had a transposition deadline of 31 December 2023, and the rules apply to fiscal years starting in January 2024. DAC9 extends administrative cooperation and information exchange for Pillar Two information returns. The Council’s 14 April 2025 notice set 31 December 2025 as the deadline for Member States to adopt and publish measures implementing DAC9.

No. The Commission adopted its Business in Europe: Framework for Income Taxation (BEFIT) proposal on 12 September 2023; it is a proposal, not currently operative EU law. It would introduce common rules for computing eligible group members’ tax bases using their financial accounting statements, then allocate results among them. Member States would still be able to adjust allocated tax bases under national rules and apply their own corporate tax rates. Unanimous agreement in the Council is required for the proposal to become law. (European Commission: BEFIT)
