How the DGT's position has evolved
Current position
To apply the benefits of a Double Taxation Convention, it is mandatory to prove residence through a certificate issued by the tax authority of the country of residence. This document must expressly state that the taxpayer is a resident within the meaning defined in the Convention. Certificates of residence are valid for one year from their date of issuance.
The DGT's position has remained constant over time. Since 2014, the administration has systematically required a certificate issued by the tax authority justifying the status of resident to avoid withholdings. No changes in the substance of the criterion have been observed, maintaining the requirement for the document's validity and its specific content.
Turning points
