Residents in Spain are taxed on their worldwide income and withholding depends on the business link

Tax residence in Spain entails tax obligations that transcend national borders. A recent binding ruling from the Dirección General de Tributos (DGT) has specified how residents receiving income abroad must be taxed and, especially, which entity is responsible for performing Personal Income Tax (IRPF) withholding in scenarios involving international mobility and corporate groups.

What the DGT has ruled

The advisory body has confirmed that every taxpayer with tax residence in Spain must be taxed on their worldwide income, in accordance with Article 2 of the Personal Income Tax Law (LIRPF). In cases of income originating from other countries, such as China, the corresponding Double Taxation Convention must be applied.

Regarding the withholding mechanics, the DGT establishes that non-resident entities are only obliged to perform withholdings if they operate in Spain through a permanent establishment or if the income they pay constitutes a deductible expense in Spain. However, a relevant nuance is introduced for corporate groups: resident entities or permanent establishments in Spain are obliged to withhold if the worker provides services for them, even if the remuneration is paid by a linked entity.

What this means for you

If you are a professional resident in Spain working for an international structure, your obligation to declare all your global income is absolute. Complexity arises when identifying who must perform the monthly IRPF withholding. It is not always the entity that pays your salary that is responsible for the withholding; if there is a link between the foreign payer and the company where you provide services in Spanish territory, the responsibility will fall on the local entity or its permanent establishment.

What should be done

It is necessary to analyze the contracting structure and the relationship of linkage between the companies involved in the payment of salaries. The correct determination of the entity obliged to withhold avoids contingencies for both the worker and the companies. It is recommended to assess each particular situation to ensure that the application of the Double Taxation Convention and the withholding mechanics align with the operational reality of the service provided.
