Regardless of whether a person is of Spanish nationality or foreign, in the tax law, what is taken into account is the tax residence of that person. This means that whenever a person acquires the Spanish tax residency, he or she shall follow tax payment as a national.
However, there are exceptions to this rule, such as diplomats and frontier workers; and those required to pay the fees regulated in art. 44 of the Law 4/2000.
Tax residency, which is used in personal taxes, which are those that refer to a specific person, will require a minimum stay of 183 days in a calendar year in Spanish territory; not being enough the mere registration.
The main differentiation in taxation can be seen in the IPRF and IRNR, applying to foreigners I one or other way depending on the time of their stay in the country. In other taxes, taxation will be almost equal.
Accordingly, if a person from the date of arrival, until 31st December, does not spend more than 183 days in national territory, will be taxed by the IRNR; but if a longer stay is provided, his or her residence would be considered as a tax one, and shall apply to personal tax income as nationals.
It is noteworthy that the tax residence in Spain does not validate the situations of irregularity in residency means.
