Income Tax When You Live or Work in Another EU Country
Moving within the EU doesn't come with one EU tax rule. Which country taxes you depends on where you're tax-resident, national law, and the tax treaty between the two countries. Here is the framework, from the European Commission's Your Europe service — the starting point before you speak to a tax adviser.
Quick answer
There are no EU-wide rules on how people who live or work outside their home country are taxed. The country where you are tax-resident can usually tax your worldwide income. Each country defines residence differently, but you'll usually be tax-resident where you spend more than 6 months a year, and you normally remain resident at home if you spend less than 6 months elsewhere. If two countries both claim you, double tax agreements decide — and usually either credit the tax paid abroad or exempt that income at home. Employees are usually taxed where they work. Wherever you're taxed, EU rules require you to be treated like a national in the same situation.
Where are you tax-resident?
Your Europe is clear that each country has its own definition of tax residence, but the usual pattern is: you're considered tax-resident where you spend more than 6 months a year, and you normally stay tax-resident at home if you spend less than 6 months a year in another EU country. The country of residence can usually tax your total worldwide income — wages, pensions, benefits, property income and capital gains. There are exceptions: posted workers and jobseekers abroad may stay tax-resident at home even after 6 months if their permanent home and stronger personal and economic ties remain there.
When two countries want to tax you
| Your situation | Usual treatment under tax treaties |
|---|---|
| Employee who moved and works in the new country | Taxed as a resident of the new country |
| Cross-border commuter (live in one, work in another) | The work country usually taxes employment income; your residence country may also tax and give credit |
| Posted abroad | May avoid host-country tax if you stay less than 6 months in a year and are paid by your home employer |
| Self-employed providing services across a border | Taxed where you provide services if you have a fixed base or permanent establishment there |
| Retired with a pension from another country | Depends on the tax treaty; risk of double taxation |
Double tax agreements usually spare you from paying twice, in one of two ways: tax paid in the work country is offset against tax owed at home, or the income is taxable only in the work country and exempt at home. Note that if the work country's rate is higher, that's the rate you end up paying. To claim relief you may need to prove where you're resident and that you've already paid tax.
Cross-border commuters and "fictitious residence"
If you live in one EU country but earn all or almost all of your income in another and pay tax there, the country where you earn it must give you the same reliefs and allowances as a resident — personal allowances or a joint return with your spouse, for example. Some treaties even treat you as tax-resident there. You can't claim a full set of resident allowances in both countries, and tax authorities share information to check.
Equal treatment
Under EU rules, you should be taxed in the same way as nationals of the country where you're tax-resident, in the same conditions. Your Europe gives examples: family allowances and childcare deductions even if the costs arise in another EU country, mortgage interest deductions for a home in another EU country, and joint assessment with your spouse where that country allows it.
Before you move
- Count your days. Six months is the usual tipping point, but check your destination's own definition.
- Find the treaty. Most EU countries have double tax agreements with each other; the treaty decides the details.
- Keep proof of residence and taxes paid — you'll need it to claim relief.
- Get advice for complex cases: the tax authorities of either country can clarify your status.
Key takeaways
- No EU-wide tax rule: national law and treaties decide.
- Usual residence test: more than 6 months a year.
- Residents are usually taxed on worldwide income.
- Treaties usually prevent double tax via credit or exemption.
FAQ
Which country taxes me if I move to another EU country?
Usually the country where you're tax-resident, which can tax your worldwide income. You're typically resident where you spend more than 6 months a year, but each country has its own definition and tax treaties can override it.
Is there an EU rule on income tax for people working abroad?
No. There are no EU-wide rules on how people living or working outside their home country are taxed. National laws and bilateral double tax agreements decide.
How do double tax agreements stop me paying tax twice?
Usually either the tax you paid in the country where you work is offset against the tax you owe at home, or that income is taxable only in the work country and exempt at home.
Do cross-border commuters get tax allowances?
If you earn all or almost all of your income in the country where you work and pay tax there, it must give you the same reliefs and allowances as a resident.
