Managing Tax Residency and Healthcare When Relocating Internationally as a Remote Worker

The Two Things Remote Workers Worry About Most And How to Actually Handle Them

Ask any European professional who has relocated internationally what kept them up at night, and the answer is almost always the same: Taxes and healthcare.

Not because they're trying to avoid either. But because the moment you cross a border with a laptop and a business, the rules that governed your entire adult life, where you pay tax, who covers your healthcare, what you're entitled to, suddenly become unclear.

This article untangles both. Not to replace professional advice, but to give you a clear picture of what you're actually dealing with, so you can ask the right questions and make the right decisions.

Tax Residency: What It Actually Means

Tax residency determines which country has the right to tax your worldwide income. And unlike your passport, it can change, sometimes without you realising it. Most people have heard of the 183-day rule: spend fewer than 183 days in a country and you're not tax resident there. This is the starting point, not the full picture.

Think of it like a speed limit. The 183-day rule is the number on the sign. But road conditions, local enforcement, and the actual law in that jurisdiction all affect what it means in practice and ignoring those details won't protect you if something goes wrong.

Many EU countries have additional criteria that establish tax residency independently of the day count:

Centre of vital interests: Where your family lives, where your bank accounts are, where your social and professional life is anchored.

Permanent home: Whether you maintain a home available to you in a country, even if you're not there most of the year.

Habitual abode: Where you spend time on a regular basis, even without a fixed address

France, Germany, Italy, and Spain all have domestic tax laws that can establish residency under criteria beyond the 183-day threshold. If you've left but your spouse is still there, or you kept the apartment, or you're registered on the electoral roll, you may still be tax resident in the country you thought you left.

Exit Tax and the Departure Process

Leaving a country for tax purposes is not always as simple as physically leaving. Several EU countries, including Germany, the Netherlands, and France have formal exit tax provisions or require you to de-register correctly to sever tax residency.

Getting this wrong in either direction, assuming you've left when you haven't, or not establishing new residency somewhere — creates a gap. And tax authorities in your home country will fill that gap by continuing to treat you as resident there.

Double Tax Treaties

If you end up with potential tax residency in two countries simultaneously, double tax treaties determine which country takes priority. The EU has an extensive network of bilateral tax treaties, and most follow the OECD model — working through a tiebreaker hierarchy that starts with permanent home, moves to centre of vital interests, then habitual abode, then nationality.

The treaty exists to protect you from being taxed twice on the same income. But it only helps if you know it applies and understand which country wins the tiebreaker in your situation. Alaway and I mean ALWAYS consult with a licensed and professional accountant who understands the law in each of your countries.

Healthcare: The Gap Nobody Plans For

Tax residency gets most of the attention. Healthcare is where people get genuinely caught out. In most European countries, your access to public healthcare is tied to your social insurance contributions, which are tied to where you work or live. The moment you leave and stop contributing, your entitlement begins to wind down.

The EHIC and Its Limits

The European Health Insurance Card covers temporary stays across EU/EEA countries for medically necessary treatment. It is not a substitute for comprehensive healthcare coverage. It doesn't cover everything, it has limits on duration, and it doesn't apply in countries outside the EU/EEA.

For someone who has relocated, rather than travelling temporarily, the EHIC is not a solution. But rest assured, there are plenty of great options available. I’ve tested many and picked my favourites.

Social Security Contributions Across Borders

EU Regulation 883/2004 coordinates social security for people moving within the EU. In general, you contribute to social security in one country at a time — usually where you work. For employed remote workers, this is typically the country of the employer. For self-employed professionals, it's usually where you carry out your work.

But "where you carry out your work" when you work online and move frequently is genuinely ambiguous, and the regulation has gaps, particularly for digital nomads who don't establish clear residency anywhere. That’s not your fault, the laws on this are still behind and it’s the land of grey-zones. Which means it’s especially important to pay attention.

What Actually Works

Most location-independent professionals end up with a combination approach:

Private international health insurance covers the gap between what public systems offer and what you actually need when abroad. I LOVEPrivate international health insurances, they are so much more advanced and flexible than let’s say insurance companies in Germany. And they enable me to visit private praxises (which means easy appointments, actual time with the doctors and a cuppa coffee at arrival — epic!).
Policies vary significantly in what they cover, so reading the fine print on pre-existing conditions, country exclusions, and coverage limits matters.

Establishing clear social security contributions in at least one country, ideally aligned with your tax residency — creates a clean record and avoids the compounding problem of gaps that become harder to resolve the longer they exist.

Knowing your A1 certificate situation if you're working within the EU. The A1 certificate is a document that confirms which country's social security legislation applies to you — useful when you're operating across multiple EU countries and need to demonstrate you're covered.

The Part That Connects Everything

Tax residency and healthcare don't exist in isolation. They connect to your company structure, your banking, your contracts, and your operational setup. A decision that makes sense for your tax situation might create a complication for your social security. A healthcare solution that works in one country might not be valid in the next (there are great global solutions though, so no need to panic yet).

This is why the "I'll figure it out when I get there" approach tends to be expensive. Not because the problems are unsolvable, they almost always are, but because solving them retroactively costs more time, money, and stress than building the structure correctly from the start.

It's the difference between designing a house with the plumbing in mind versus knocking holes in the walls after you've moved in.

Getting Clarity on Your Specific Situation

Every relocation is different. The right answer for a German freelancer moving to Portugal is not the same as the right answer for a Dutch consultant splitting time between Estonia and Southeast Asia. The principles are consistent. The details depend on your life.
