How is an EU Inc taxed?

Updated 2 Aug 2026 · transactional

Based on the proposal (COM(2026) 321), not yet adopted. Tax treatment described here is the proposal's design and may change in negotiation.

Proposal only. Everything below describes COM(2026) 321 as proposed. EU Inc is not law, and tax is the area where member states guard sovereignty most tightly — expect movement before the final text.

The shortest accurate answer: an EU Inc is taxed like a national company of the member state where its registered office sits. The proposal deliberately harmonises company law, not tax. That choice is both EU Inc’s political feasibility and its most-criticised limit.

What stays national

• Corporate income tax — base, rate and filing obligations are those of the registered-office state. A France-seated EU Inc pays French corporate tax; an Estonia-seated one is under Estonia’s distribution-based regime. The form does not change the tax bill.
• VAT — EU-harmonised as for any company (the VAT directive applies), but rates and administration remain national.
• Dividends, capital gains, payroll and social contributions — entirely national, subject to existing double-tax treaties.

The consequence founders should internalise: EU Inc does not create tax arbitrage. Choosing the registered office is choosing a national tax regime, and the proposal requires a genuine link to that state — the “letterbox company” risk is one of the negotiation’s active fronts.

What the proposal does harmonise

Two administrative things, and one substantive one:

1. Once-only registration. Tax and VAT identifiers are issued through the single registration procedure — no separate applications, no re-submission of the same documents to national tax authorities. This is plumbing, not policy, but it is the part founders will feel first.
2. A single certificate recognised across registers, which reduces the friction of proving the company’s existence to foreign tax administrations.
3. EU-ESO timing. The one genuine tax rule in the proposal: employee stock options under the harmonised EU-ESO framework are taxed at sale of the shares, not at grant or exercise. Rates stay national; only the when is harmonised. Details and per-country treatment: EU-ESO tax by country.

The “28th tax regime” debate

The gap between harmonised company law and 27 national tax systems is well understood in Brussels. In June 2026, Parliament’s ECON committee adopted an own-initiative report (Ódor) urging the Commission to study an optional EU tax regime covering withholding tax, the corporate tax base, loss relief and employee share schemes. It is a non-binding political signal on a separate procedural track — nothing to plan around yet. We track it in the news and on the tracker.

Practical read for founders

• Model your tax burden on the national regime of the intended registered office, exactly as you would for a national company there.
• Treat EU-ESO deferral as the one tax feature you can plan around — and even that only once adopted.
• If your incorporation decision hinges on tax, EU Inc changes less than the headlines suggest; the comparison that matters is national form vs national form. Start with cost and eligibility, then the comparisons.
