For companies, the following applies:

But: You can have tax domicile in another country if you live abroad for more than 6 months a year or have your main income from another country.
Sometimes the tax authorities of two countries can consider that a person is taxable in their country, then there can be a dispute between the tax authorities about where the person should be considered to have his tax domicile.
