Remote work visas went from a novelty to a standard policy instrument in about four years. Portugal, Spain, Italy, Greece, Croatia, Estonia, Malta and dozens of others now offer some version, usually requiring proof of foreign income above a threshold and private health insurance.
What almost none of them state plainly is the tax consequence, because immigration ministries issue visas and finance ministries decide tax, and they do not always coordinate.
The visa does not decide the tax
Tax residency is determined by national law and, where two countries both claim you, by the tie-breaker in the relevant treaty. A visa is relevant only insofar as it allows you to be present long enough to satisfy a residence test. The tests themselves are described in the 183 day rule.
Three outcomes are possible and all three occur in practice.
- You become tax resident in the new country. Most visas are issued for twelve months or more, and staying that long will satisfy the day count almost everywhere. Worldwide income then falls into the local system.
- You remain tax resident at home. Possible for shorter stays or where your permanent home, family and economic centre stay put. The treaty tie-breaker may deliver this even after 183 days.
- You are resident in neither, which is worse than it sounds. Leaving your home country without establishing residence elsewhere frequently fails to end the home liability, and some countries require a residence certificate from the new state before releasing you.
Some schemes come with a tax regime attached
Croatia and Malta are the genuinely favourable cases. Spain's is favourable if you qualify for the flat rate regime, described in the Beckham law. Estonia is admirably honest about offering nothing.
The employer problem
The individual's tax position is only half of it. An employee working from another country can create a taxable presence for the employer, known as a permanent establishment, which brings corporate tax filing obligations in a country the company has never operated in.
Separately, the employer may acquire a payroll withholding and social security obligation in the host country. This is why so many companies that were relaxed about remote work in 2021 became strict about it later. It is not usually about trust.
The social security question in Europe is answered by the coordination regulations rather than by tax treaties, and the relevant document is the A1 certificate, covered in the A1 certificate.
What to settle before going
- Get written permission from the employer, naming the country and the period. Verbal agreement is worth nothing when a tax authority asks.
- Establish whether you will break residence at home, and what that requires. Some countries need a formal deregistration, some need a certificate from the new state, and some apply a split year rule only on election.
- Check the treaty between the two countries, specifically the employment article and the tie-breaker.
- Check the social security position separately. It will not follow the tax answer.
- Look at what happens to pension contributions, health cover and any employer insurance while you are away. These usually stop and are rarely mentioned.
The realistic picture
For a stay of a few months where you remain resident at home and your employer has agreed, the position is usually manageable. For a stay of a year or more the intention is to move country, and the honest way to plan it is as a relocation rather than as an extended holiday. That means comparing net pay properly, not just the visa conditions.
