DoubleTaxationTax residence status: how the check works
The service determines which country you are a tax resident of when your life is connected with two countries. The check is free, needs no sign-up and takes a few minutes.
Three steps
- Choose a country. Your citizenship, the other country you are connected with, the tax year and — if you moved this year — the date you left or arrived.
- Answer the questions. Home, family, work, number of days, citizenship — only the questions that matter in your situation. If you don't know an answer, choose “I don't know”: the conclusion will show both outcomes.
- Get the conclusion. Which country you are a resident of, which taxes are due and where, and the legal basis.
Who this is for
- U.S. citizens and green card holders who moved abroad and need to know who taxes what
- Americans working remotely for U.S. clients or employers from another country
- People with a home, family or business both in the U.S. and in another country
- Anyone returning to the U.S. after years abroad

How the conclusion is reached
- First, the domestic law of each of the two countries: day thresholds, place of residence, centre of vital interests, citizenship.
- If both countries treat you as a resident, the tie-breaker rule in Article 4 of the tax treaty applies: permanent home, centre of vital interests, habitual abode, nationality, mutual agreement.
- For criteria that call for judgment, court practice and tax authority guidance are taken into account; the “Reliability of the conclusion” scale shows how much the conclusion depends on them.
- For specific types of income — salary, dividends, pensions, rent and more — the treaty rules: which country may tax and how double taxation is relieved.
What you get
- A conclusion on your tax residence with the reasoning and links to the laws, the treaty and court decisions.
- Which taxes are due and where; for the income you enter — rates, tax credit and the amount still to pay.
- Next steps: certificate of residence, obligations in each country, what to do when leaving, exit tax, how the year of the move is split.
- A check of the previous year with the same answers, a PDF report and a link to the result that you can share.
Questions
I am a U.S. citizen living abroad — do I still pay U.S. tax?
Yes, the United States taxes its citizens on worldwide income wherever they live, and tax treaties keep that right through the «saving clause». You still file a U.S. return; double taxation is usually relieved through the foreign tax credit or the foreign earned income exclusion.
What is tax residence?
It is the status that lets a country tax all of your income, including income from abroad. For non-citizens the U.S. uses the green card test and the substantial presence test; other countries look at your home, the center of your life and the days you spend there.
Is this legal or tax advice?
No. It is an information service that shows how the rules apply to your answers. Tax authorities and courts may assess your circumstances differently, so for important decisions consult a qualified adviser.
Are my answers stored?
No. The calculation runs in your browser and your answers are not sent anywhere. For statistics we only add +1 to anonymous daily counters (for example, «Germany → resident of Germany») — no IP address, cookies or identifiers.
Is it free?
Yes, completely, with no sign-up.
Privacy
Your answers are processed in your browser and are not sent to the server; no sign-up or cookies are needed. For statistics we count only the country and the overall conclusion, anonymously. More in the privacy policy.
Important
The conclusion is general information, not tax or legal advice: it depends on your answers and on circumstances the service cannot see, and the law changes. How we work with sources is described in the methodology. To apply the conclusion correctly, consult a lawyer.
