What Is the Unified European Company (S.EU)? Everything You Need to Know

Let's start with what actually happens today.

A founder in Berlin builds a product. It works. She wants to hire engineers in Lisbon (cheaper, great talent pool), open a sales office in Amsterdam (closer to enterprise clients), and raise a Series A from a Paris-based VC.

Here's what she's facing: German company law for the parent entity. Portuguese employment law for the engineers. Dutch regulations for the sales office. French expectations for the investment structure. Four legal systems. Four sets of advisors. Four invoices.

This is why European startups do the "Delaware flip." They give up and reincorporate in the US, where one legal system covers a $25 trillion economy.

The Unified European Company—the S.EU—is supposed to fix this.

The Delaware Flip: Who's Already Left

Spotify: Founded in Sweden, incorporated in Luxembourg, listed on NYSE.

Klarna: Swedish fintech, restructured through the Netherlands.

UiPath: Started in Romania, incorporated in Delaware before going public.

Revolut: UK-founded, Lithuanian banking license, complex multi-jurisdiction structure.

What's Actually Being Proposed

On January 21, 2026, the European Parliament voted 492-144 to recommend a new company type: the S.EU (Societas Europaea Unificata). Some people call it "EU Inc."

The pitch is simple: one company form that works the same way in all 27 member states.

FeatureWhat It Means
48-hour incorporationFully online, using EU digital ID (eIDAS). No notary. No paper.
€1 minimum capitalCompare to €25,000 for a German GmbH or €120,000 for an SE.
Cross-border seat transferMove your company from Portugal to Ireland without dissolving. Contracts stay intact.
Single digital portalOne EU platform for all filings, built on existing BRIS infrastructure.
Standardized ESOPsPan-European employee stock ownership plans. Attract talent across borders.

Why Now? Because Europe Is Losing

Two reports dropped in 2024 that scared policymakers. The Letta Report in April. The Draghi Report in September. Both said the same thing: Europe's single market isn't single.

"A voluntary 28th company rulebook harmonising legislation concerning corporate law and insolvency, as well as a few key aspects of labour law and taxation, should be explored."

Regulatory fragmentation on goods~44%
Regulatory fragmentation on services~110%
Average cost of cross-border restructuring€50,000 – €200,000+
Time to dissolve and reincorporate3–12 months

They Tried This Before. It Didn't Work.

The EU already has a pan-European company form. It's called the Societas Europaea (SE), and it launched in 2004 with similar ambitions. Twenty years later, only about 3,000 SEs exist. Germany alone registers over 100,000 new GmbHs every year.

The S.EU is explicitly designed to avoid the SE's mistakes: low capital, simple formation, open to anyone.

What the S.EU Won't Fix

Here's where it gets complicated. The S.EU harmonizes company law. It does not harmonize everything else.

Taxes stay national. An S.EU registered in Ireland pays Irish corporate tax (12.5%). One registered in France pays French rates (25%). If you're incorporating based on tax, you're still jurisdiction shopping.

Labor law stays national. Hire someone in Germany, follow German employment law. The S.EU doesn't let you pick your favorite labor regime.

The bottom line: The S.EU is a better wrapper around the same underlying complexity.

What We See From the Data

We connect to company registries across Europe. We see the raw filings, the entity structures, the ownership chains. Here's what the S.EU will change from a data perspective.

Data perspective infographic on S.EU impact

More entities, faster. 48-hour incorporation means more companies appearing in registries. Manual verification doesn't scale when incorporation friction approaches zero.

Mobile entities. The supplier you onboarded in Poland could be a Dutch entity by next quarter. Verification isn't one-and-done anymore.

Same underlying registries. The S.EU will use BRIS infrastructure. BRIS gives basic existence data. It doesn't give financials, ownership depth, or directors. That won't change.

You have at least 18 months before this affects anything. Use that time to understand what's coming, not to panic.

Who Wins, Who Loses

Winners

  • Founders building pan-European companies
  • VCs wanting standardized deal structures
  • Estonia, Ireland, Lithuania (attract S.EU registrations)

Losers

  • Corporate lawyers billing for restructuring
  • Countries with complex, high-fee incorporation
  • Anyone profiting from EU fragmentation

The Bottom Line

The S.EU is real progress. It's not a revolution.

It will make cross-border incorporation easier. It will reduce some legal costs. It will let companies move within Europe without dissolving.

It will not create a true single market. Taxes stay national. Labor law stays national. The S.EU is a better wrapper around the same underlying complexity.

Key Takeaways

For Compliance Teams
Prepare for more entities, faster formation, and mobile jurisdictions.
For Founders
This might make "stay in Europe" viable. Don't wait—build now, let S.EU simplify later.
For Everyone
Watch the Commission proposal. The Parliament vote was a wish list. Legislation is where reality sets in.

Frequently Asked Questions

What is the S.EU (Societas Europaea Unificata)?

The S.EU is a proposed pan-European company form that would let founders incorporate a single entity to operate across all 27 EU member states. Also called "EU Inc.," it's designed to be fully digital, take 48 hours to set up, and cost under €100. Unlike national company forms (GmbH, SAS, BV), one S.EU would work everywhere in Europe without needing subsidiaries in each country.

What is the difference between SE and S.EU?

The Societas Europaea (SE) requires €120,000 minimum capital and can only be formed by existing companies from multiple EU countries. The S.EU needs just €1 and anyone can form one. The SE was designed for large corporations doing cross-border mergers. The S.EU targets startups and SMEs wanting to scale across Europe. In 20 years, only 3,000 SEs have been registered—the S.EU aims to change that with simpler rules.

How do I register an EU Inc. / S.EU company?

You can't yet—the S.EU doesn't exist as law. The European Parliament voted to recommend it in January 2026, but the Commission still needs to publish its formal proposal (expected Q1 2026). After negotiations between Parliament and Council, implementation is expected 2027-2028 at earliest. When it launches, registration will be fully online through a single EU portal using eIDAS digital ID.

Can a non-EU citizen start an S.EU company?

Under the current proposal, no. The Parliament's recommendations limit S.EU formation to EU residents and EU-based entities. A US or UK founder would need an EU co-founder, an existing EU subsidiary, or EU residency to form an S.EU. This could change during negotiations—some argue it limits the framework's competitiveness. Watch the Commission proposal for final eligibility rules.

What tax rate does an S.EU company pay?

The S.EU doesn't create a unified EU tax rate. You pay corporate tax in the country where you're registered: Ireland (12.5%), Germany (~30% effective), France (25%), etc. The S.EU harmonizes company law, not tax law. If you want lower taxes, you're still jurisdiction shopping—but at least with the S.EU you can move your seat without dissolving the company.

Can I move my S.EU company to another country?

Yes—cross-border seat transfer is a core feature. You can move your registered office from, say, Portugal to Ireland without dissolving the Portuguese entity and creating a new Irish one. Your contracts, licenses, and legal identity stay intact. But anti-avoidance rules will apply: substance requirements mean you need real operations, not just a mailbox. Purely tax-motivated moves will face scrutiny.

Does the S.EU simplify hiring employees across Europe?

Not directly. Employment law stays national. Hire someone in Germany, follow German labor law—minimum wage, working hours, termination rules, social security contributions. The S.EU doesn't let you pick your favorite labor regime. What it does simplify: you don't need a German subsidiary to employ German workers. You can hire them through your S.EU directly. The legal entity is simpler; the employment compliance isn't.

When will the S.EU / EU Inc. be available?

Realistically, 2027-2028 at earliest. The January 2026 Parliament vote was a recommendation, not law. The Commission publishes its legislative proposal in Q1 2026. Then comes 12-18 months of negotiations between Parliament and Council. If it's a directive (likely), add time for 27 national transpositions. Don't plan your 2026 corporate structure around the S.EU—it's not coming that fast.

What is the "28th regime" for EU companies?

The "28th regime" refers to an optional EU-level legal framework that exists alongside the 27 national systems. Instead of choosing between German, French, or Dutch company law, founders could opt into this EU-wide rulebook. The S.EU would be this 28th option. It doesn't replace national company forms—it adds a pan-European alternative. Companies choose which rules to follow based on their needs.

Is the S.EU better than incorporating in Delaware?

Depends on your market. Delaware gives you one legal system covering 330M people and access to US capital markets. The S.EU would give you one legal system covering 450M people across 27 countries. Delaware wins on tax simplicity (federal + state). S.EU loses on tax fragmentation (27 national systems). For European-focused businesses, S.EU could eliminate the "Delaware flip." For US-focused businesses, Delaware still makes sense.

How will the S.EU affect KYB and company verification?

Three ways: (1) More entities to verify—48-hour incorporation means more companies appearing faster in registries. (2) Mobile jurisdictions—seat transfers mean a company's country can change mid-relationship; one-time verification isn't enough. (3) Same data gaps—the S.EU will use BRIS infrastructure, which provides basic existence data but not financials, ownership depth, or directors. Compliance teams will need continuous monitoring, not point-in-time checks.

Will the S.EU include standardized stock options (ESOPs)?

Yes—EU-ESOP is part of the broader EU Inc. initiative. Currently, employee stock options are taxed differently in every EU country, creating headaches when employees move across borders or when startups hire across Europe. The S.EU framework proposes a harmonized ESOP structure with consistent tax treatment. This could be a major advantage for startups competing for talent against US companies with simpler equity compensation.

Can I convert my existing company to an S.EU?

The proposal includes conversion pathways, but details aren't finalized. Likely options: (1) Convert an existing national company (GmbH, SAS, BV) into an S.EU. (2) Merge multiple national entities into one S.EU. (3) Create an S.EU holding company over existing subsidiaries. Expect the Commission proposal to clarify conversion procedures, timelines, and any restrictions based on company size or sector.

Where can I track S.EU / EU Inc. legislation?

Primary sources: European Parliament Legislative Observatory (procedure 2025/2079(INL)) for Parliament actions. EUR-Lex for Commission proposals when published. Secondary sources: EU-INC.org (the advocacy group that pushed for this), Allied for Startups, and the European Startup Network publish regular updates. Law firms like Fieldfisher and Osborne Clarke track regulatory developments with client alerts.

What are the criticisms of the S.EU proposal?

Trade unions worry about a "race to the bottom" on labor standards—companies moving to countries with weaker worker protections. Member states fear loss of control over company law and reduced fee revenue from national registrations. Some argue the SE already exists and just needs reform rather than a new framework. Others point out that without tax harmonization, the S.EU solves the wrong problem. The negotiation will address these concerns—or the proposal will stall like previous attempts.
