Answers · current to October 2026

A permit, a tax residence, a passport.

These are 3 different things, granted by 3 different authorities on 3 different clocks. What each status decides in the published rules, and what it leaves open.

In short, current to October 2026

  • A residence permit is an immigration status. Tax residence is a separate test under tax law, and holding 1 does not settle the other.
  • In the UAE a residence permit holder meets the tax residence definition with 90 days of presence and a home, a job or a business there, or with 183 days. Cabinet Decision No. 85 of 2022.
  • Citizenship follows its own clock. Portugal asks for more than 183 days in 12 months for tax residence, and since 2026 for 10 years of residence for citizenship.
  • In almost every country on the board citizenship does not decide tax. The United States is the large exception: it taxes its citizens wherever they live. French nationals living in Monaco stay within French income tax under the 1963 convention.

5 statuses

What each one decides.

Residence permit or visaThe immigration authority

The right to live in the country, and often to work there, for the life of the permit.

Does not decide aloneTax residence. That is tested under tax law, year by year.

Tax residenceTax law, applied by the tax authority

Which country taxes a person as its own resident, in most countries on worldwide income.

Does not decide aloneA right to enter or stay. A person can be tax resident in a country where the permit has lapsed, and hold a permit where they are not tax resident.

Tax residence certificateThe tax authority, on application

Evidence of tax residence for a stated period, used to claim relief under a tax treaty.

Does not decide aloneThe other country's own test. It applies that test first, and the treaty's tie-breaker decides where both claim the person.

DomicileCommon law, in the countries that use it

In Malta, whether a resident is taxed on worldwide income or only on what is remitted.

Does not decide aloneResidence. A person can live for years in a country without a domicile there.

CitizenshipNationality law

A passport, the right to live in the country without a permit, and political rights.

Does not decide aloneTax, in almost every country on the board. The United States is the large exception: it taxes its citizens wherever they live.

Questions

The short answers.

Is a residence permit the same as tax residence?

No. A residence permit is granted by the immigration authority, and tax residence is tested under tax law.

A person can hold a permit without being tax resident, and can be tax resident after a permit has lapsed. Each country on the board publishes its own tax test.

Does a golden visa make a person tax resident?

Not by itself. It gives the right to live in the country.

Tax residence then depends on the days spent there, the home and the ties, under the tax test of that country.

What does a tax residence certificate prove?

That the issuing tax authority treats the holder as its resident for a stated period.

It is used to claim treaty relief. The other country still applies its own test, and the treaty's tie-breaker decides where both claim the person.

Does citizenship decide where a person pays tax?

Rarely. The United States is the large exception: it taxes its citizens wherever they live.

French nationals living in Monaco stay within French income tax under the 1963 convention between the 2 countries. Elsewhere on the board, tax follows residence and the source of the income.

The rules move. Be told when they do.

Sent when it earns the send, not on a schedule. Never shared, one tap to stop.

Tax figures use a simplified marginal model with indicative 2026 brackets for a non-US single filer, ignore social contributions, most deductions, wealth taxes, and treaties, and are not advice. Residence rules change often. Verify before acting.
