Visa and Residency Basics for Remote Workers
Immigration status, the right to work and tax residency are three separate questions with three separate answers. Conflating them is how people get into trouble that a good data plan cannot help with.
This is general orientation, not legal or tax advice. Rules change frequently and vary by nationality, employer structure and personal circumstances. Before acting, check the official source for the country involved and, where the stakes justify it, take professional advice.
Three questions, not one
The first question is whether you may enter and remain: a visa or visa-free entry, with a permitted duration. The second is whether you may work while you are there, which is a distinct permission and is not automatically granted by the first. The third is where you owe tax, which follows its own rules and pays no attention to what your entry stamp says.
Most confusion comes from assuming the first answer settles the other two. A tourist entry generally permits neither local employment nor, in many countries, working for a foreign employer while physically present — even though enforcement varies enormously and a great many people have done exactly that without incident.
The Schengen arithmetic
For visa-exempt visitors, the Schengen area permits 90 days of presence in any rolling 180-day period across the whole area, not per country. The window rolls: on any given day, count backwards 180 days and add up your days of presence. Leaving for a week and returning does not reset it.
Two details catch people out. Days of entry and exit both count as full days of presence. And the rule applies to the area as a whole, so a month in Portugal followed by a month in Greece consumes two months of the same allowance. The European Commission publishes a calculator; use it rather than counting in your head, and keep your entry and exit stamps or boarding passes.
A simple dated list of entries and exits, with scans of stamps and boarding passes, takes a minute a month and answers almost every question an immigration or tax authority might later ask. It is also the only reliable way to count Schengen days once you have made more than a few trips.
Digital nomad and remote-work permits
A growing number of countries now issue a residence permit specifically for people employed or self-employed outside the country. Portugal, Spain, Estonia, Croatia, Costa Rica and others each run their own version, and the details differ substantially — but the shape of the requirements is remarkably consistent.
- Proof of income above a stated threshold, usually evidenced with several months of bank statements and a contract or client agreements.
- Proof that the income is foreign — an employment contract with a company outside the country, or invoices to foreign clients.
- Health insurance valid in the country for the whole permit period.
- Accommodation evidence, often a lease of a minimum length.
- A criminal record certificate from your country of residence, frequently requiring an apostille and a sworn translation.
Budget more time than the published processing estimate. The slow steps are rarely the application itself; they are the apostille, the translation and the appointment slot at a consulate. Starting three months ahead is not excessive.
A permit that lets you stay legally will often also make you tax resident. That is not a flaw in the permit — it is the trade you are making, and it should be a deliberate one.
Tax residency is a separate machine
Most countries treat you as tax resident if you are present for more than roughly 183 days in a tax year, but the threshold is only the crudest test. Many jurisdictions also look at where your permanent home is, where your economic interests sit, and where your family lives. It is entirely possible to meet the residency test of two countries at once, which is what double taxation treaties and their tie-breaker rules exist to resolve.
Two specific risks are worth naming. Leaving your home country's tax net is often harder than entering another's; some countries require formal deregistration and continue to treat you as resident until you complete it. And if you are employed rather than freelance, your physical presence abroad can create a permanent establishment or a payroll obligation for your employer in that country — which is why many companies restrict where staff may work from, and why employer-of-record arrangements exist.
Insurance, healthcare and the boring documents
Travel insurance and health insurance are different products, and permit applications almost always want the latter. Check whether a policy covers you in every country on your route, whether it covers pre-existing conditions, and what happens if you are outside your home country for more than a year — many policies quietly stop at that point.
Keep certified copies of your passport, your permit or visa, your insurance certificate and your accommodation contract in encrypted cloud storage as well as on paper. Renewals, bank account openings and even some coworking contracts will ask for them, usually at the least convenient moment.
A practical sequence
Decide how long you want to stay, and check what that duration requires for your nationality on the official government source rather than a blog. Work out whether the stay creates a tax residency question and, if it might, speak to an accountant before you go rather than in April. If a permit is needed, start the document chain early because the apostille is the bottleneck. Keep the movement log from day one. And separate the question of where you want to live from the question of what your employer's policy actually permits — that conversation is much easier before the flight than after it.
