This is a curated directory of professionals and service providers with expertise relevant to EU Inc preparation. Any paid or priority placement will be clearly labeled. Editorial content and the EU Inc tracker are editorially independent from partner relationships.

Partner directory launching Summer 2026

We are building a curated network of tax advisors, law firms, incorporation specialists, and employment experts with cross-border EU expertise. The first listings are expected in Summer 2026.

Table Of Contents

Find practical support for setup, tax planning, fundraising, hiring, branches, and conversion.

EU Inc. creates a single EU-level company form, but the work around it — tax structuring, employment, equity, conversion, branch rollout — is still cross-border and still requires people who know what they are doing in specific jurisdictions. This page connects you with partners who understand both the EU-level framework and the national-level follow-through underneath it.

Important: EU Inc. is still a proposal, not final law. Partners here can help you prepare now — tax structuring, conversion feasibility, employment setup, and equity design all start before the law is final. Other engagements will depend on the final legislative text.

We are independent. Listings are not a substitute for your own legal or tax review.

Who this page is for

Founders deciding where to register and how to structure. Existing companies — GmbH, SAS, BV, SRL — assessing conversion. Operators rolling out to multiple Member States. Investors and counsel looking for implementation support. Teams hiring across borders and needing local employment, payroll, and equity coordination.

Find support by need

Tax planning and structuring

The most requested category — and the biggest gap in the current EU Inc. discussion.

The proposal does not harmonise tax. Where you register determines corporate tax, VAT, payroll tax, and how the EU-ESO is treated. A tax advisor who understands EU Inc. should be able to model outcomes across jurisdictions before you commit, not just file returns after the fact.

You need this for: registered-office tax analysis, VAT planning across Member States, transfer pricing, payroll tax coordination, EU-ESO tax treatment, and conversion tax neutrality. Look for coverage across at least 3–5 relevant Member States, startup/VC experience, and willingness to work alongside company-law counsel.

Setup and incorporation

Formation goes through a digital EU central interface — but the structure decisions, shareholder agreements, articles-of-association choices, and post-registration follow-through (bank, tax ID, VAT, employer registration) still require professional support, especially for founders choosing between Member States.

You need this for: structure decisions, registered-office selection, shareholder agreements, and the first 30 days after registration. Look for experience with digital-first formation and understanding of what the EU system handles versus what requires local action.

Conversion from national company forms

For companies exploring a move from GmbH, SAS, BV, SRL, or another national form into EU Inc.

Conversion is one of the most complex areas. The proposal allows it (Articles 106–107), legal personality continues, and procedures follow Directive 2017/1132 — but it requires shareholder approval, asset valuation, creditor protection, and employee-participation review. Tax neutrality is not harmonised and depends entirely on each Member State.

You need this for: conversion feasibility assessment, domestic or cross-border conversion planning, merger/division structuring, and operational transition. Look for experience with 2017/1132 cross-border procedures, creditor and employee-participation compliance (particularly German codetermination), and ability to coordinate across old-seat and new-seat jurisdictions.

EU Employee Stock Option Plan (EU-ESO)

The EU-ESO framework (Articles 71–87) is harmonised at the EU level — plan structures, beneficiaries, vesting, exercise, portability — but Member States control tax treatment. Implementing it across a distributed team means understanding how each country taxes the options and what reporting the employer owes.

You need this for: plan design, grant documentation, trustee arrangements, and cross-border tax treatment mapping. Look for experience with equity compensation across multiple European jurisdictions, not just one domestic market.

Fundraising and governance

The proposal enables multiple share classes, digital share transfers, no minimum capital, and a digital share register — a significantly better foundation for fundraising than most national forms. But SAFE agreements remain national contract law, and investor documents need to be adapted for the EU Inc. structure.

You need this for: financing rounds, SAFE preparation, share class design, cap-table management, board and shareholder resolutions, and data-room setup. Look for VC/startup transaction experience and cross-border investor coordination.

Employment, payroll, and team rollout

Employment law is entirely national. Every hire in a new Member State means new contract requirements, payroll obligations, social security, and potentially a works council. EU Inc. does not change this — but it does make the equity and branch layers simpler.

You need this for: local employment contract review, payroll setup, contractor classification, social security coordination, and onboarding documentation. Look for coverage in the countries you are hiring in, EOR (Employer of Record) capability, and integration with ESOP administration.

Branch expansion

The proposal's "once-only" branch registration (Articles 35–40) distributes your data to tax and social-security authorities through BRIS — but does not complete local TIN applications, payroll setup, or employer registration. Each country still has its own follow-through.

You need this for: branch registration support, local tax and employer follow-through, payroll handoff, and multi-country coordination. Look for experience with BRIS, national business registers, and the ability to handle multiple countries in parallel.

Related readiness tools: Branches and cross-border operations →

Compliance, filing, and corporate secretarial

Once running, an EU Inc. needs register maintenance, annual filing, beneficial-ownership reporting, and governance record-keeping — across the EU central register and national systems.

You need this for: ongoing filings, AML compliance, EUID and BRIS requirements, and digital record-keeping. Look for coverage in your Member State(s) and experience with digital-first corporate admin.

How the directory works

We are building the partner directory now. We cover: EU company law, cross-border tax, startup/VC legal, employment, payroll/EOR, accounting, restructuring and M&A, EU-ESO, corporate secretarial, banking/KYC, and notary support where still relevant.

Every listed partner will show: countries covered, services offered, languages, startup/scaleup experience, remote or local support, pricing approach, and whether they handle conversions and cross-border work. We review applications for real cross-border experience, transparency on scope and pricing, and willingness to coordinate with other advisors rather than insisting on handling everything alone.

Any sponsored or priority placement will be labelled clearly. Editorial content and the EU Inc. tracker stay separate from commercial relationships.

Common scenarios

I am launching a new company

You probably need: registered-office tax analysis first, then setup counsel, cap-table and share structure support, and post-registration follow-through (bank, tax, employer registration).

Start with: Tax planning → Setup and incorporation → Employment (if hiring immediately).

I already have a GmbH (or SAS, BV, SRL)

You probably need: a conversion feasibility review first. Then: tax neutrality assessment, creditor and employee-participation compliance, operational mapping, and transition planning.

Start with: Conversion support → Tax planning → Employment (if multi-country team).

I want to raise from investors

You probably need: financing documentation, SAFE preparation under national contract law, share class design, approvals, cap-table management, and data-room setup.

Start with: Fundraising and governance → Tax planning (to confirm the structure works for investors).

I want to hire across borders

You probably need: local employment review, payroll setup, contractor classification, social security coordination, and EU-ESO implementation if offering equity.

Start with: Employment and payroll → EU-ESO → Tax (for equity treatment per country).

I want to open branches in other Member States

You probably need: branch registration, local tax and employer follow-through, payroll, and operational coordination with the parent company.

Start with: Branch expansion → Tax → Employment.
