Portuguese Tax Identification Number
Any foreign or domestic investor operating in the Portuguese market is required to have a Portuguese Tax Identification Number (NIF). In agreement with the Portuguese law (article 3 of Portaria 386/98, 3 of July), the same investor can only have one NIF.
Clearstream Europe AG (CEU) is acting as a withholding agent in Portugal and authorised by the Portuguese Tax Authorities to request NIFs for non-Portuguese resident investors. In order to follow such process, clients applying for relief at source or quick refund on behalf of beneficial owners that have not yet been allocated with a NIF, must submit together with the Mod 21-RFI the duly completed NIF Request available on our website under Tax forms to use Portugal.
