General Rules of Double Taxation Agreement in Spain

Júlia Tax Answer

Which country taxes income from professional activities in the event that a Double Taxation Agreement exists?


As a general rule, agreements attribute the power to tax income derived from the exercise of independent professional activities to the country of residence of the person carrying out the activity. However, this income can be subject to tax in the country in which the activity is carried out when there is a fixed base for the exercise of such activity.

Professional activities include in particular scientific, literary, artistic, educational or teaching activities, as well as the independent activities carried out by doctors, lawyers, engineers, architects, dentists and accountants.

Some Agreements contain special rules like the ones of Brazil, Canada and Sweden.


The existence of Double Taxation Avoidance Agreements (DTAA) is essential to promote foreign investments, whether they are foreign in Spain or Spanish capital abroad, as they provide legal certainty for investors and reduce the taxation of such investments.

The other 9 are at different stages of processing (Azerbaijan, Bahrain, Belarus, Cape Verde, Montenegro, Namibia, Peru and Syria). In addition, the DTAAs have been renegotiated with Austria, Belgium, Canada, Finland, India, Mexico, Romania, the United Kingdom and the United States.
