EU Freedom of Movement: Moving, Registering, Being Taxed

What EU freedom of movement really allows

EU citizens may reside, work, run a business and provide services in any member state. For stays beyond three months, member states typically attach conditions: employment, self employment, or sufficient resources combined with health cover. The right says nothing about where you pay tax; it only means residence cannot be denied to you.

Registering in the destination country

Almost every member state requires registration for longer stays, usually combined with issuing a national identification number and a tax number. Those numbers are what make you functional locally, from bank accounts to leases and insurance. Procedures vary widely, from a simple online notification to appointments with evidence of income and health cover.

Deregistering in your former country

A move is only clean for tax purposes once the ties in your former country are genuinely cut. That normally means deregistering your residence, giving up or letting the previous home, and notifying the tax office. Keeping a home available at all times can preserve unlimited tax liability in countries such as Germany or Austria, no matter where you actually spend your time.

How tax residency is determined

Each state decides under its own law whom it treats as resident, usually via a home, habitual abode or day counts. Where two states both claim you, the double taxation treaty applies tie breaker rules in sequence: permanent home, centre of vital interests, habitual abode, nationality. That sequence is the real benchmark, not your registered address.

Social security and health cover

Social security follows separate EU coordination rules that diverge from tax law. As a rule you fall under the system of the state where you work, with special rules for activity in several states and for postings. Anyone self employed across borders should have the competent system confirmed in advance, otherwise contribution gaps or double liability arise.

Cost and effort of an intra EU move

Moving inside the EU is legally simple but rarely cheap administratively: housing and deposits, translations, tax advice in two countries, and reworking insurance and contracts. Budget for a transition year in which returns are due in both states. The biggest cost driver is poor preparation, which surfaces later as queries and back payments.

When it becomes a problem

It becomes a problem when the move only happens on paper: a registered address abroad while home, family and clients remain in the old country. Equally risky is a company whose management effectively stays behind, because the company itself can then remain taxable there. Neither shows up immediately, but both surface in audits and information exchange.

Common mistakes

The classic mistake is keeping the old apartment out of convenience. The second is failing to notify the tax office and social security institutions. The third is treating 183 days as a universal threshold, when many states already attach liability to an available home or the centre of your life.

Next steps

Work in this order: assess the destination country, clarify exit consequences, complete the physical move, and only then adjust the company structure. Document leases, travel dates and invoices from day one, because that evidence decides later disputes. The Business Freedom Score gives a first assessment; binding review comes from licensed partners in both countries.

Frequently asked questions

Can I live anywhere in the EU as an EU citizen?

Yes, the right of residence applies across member states. For stays beyond three months most countries require registration plus employment or sufficient resources with health insurance cover.

Do I have to deregister in my home country?

For a clean tax exit, usually yes. Without deregistration and without giving up the previous home, unlimited tax liability can continue even if you mainly live abroad.

Where do I pay tax if I live in two EU countries?

Each state first applies its own rules to decide whether you are resident. If both claim you, the treaty tie breaker decides, starting with your permanent home and centre of vital interests.

Does the 183 day rule apply across the EU?

No. 183 days is a common criterion but neither uniform nor decisive on its own. Many states establish tax liability through an available home or the centre of your life instead.

What happens to my health insurance when I move?

Competence follows the EU coordination rules and usually attaches to where you work. Clarify which system becomes responsible before you move so you avoid gaps in cover.

Can I simply take my company with me?

The entity continues to exist legally, but the place of effective management can shift and with it the company's tax liability. Any relocation of management should be reviewed beforehand.

When do I get permanent residence rights?

After several years of continuous lawful residence a permanent residence right normally arises in that member state. The details and required evidence are set by national law.
