Portugal: New procedure to request a tax voucher and amendment of Modelo 30


Note: This announcement, originally published 14 April 2023, has been updated to add information regarding income payments. Changes have been highlighted. 

LuxCSD1 informs clients that effective


clients wishing to obtain a tax voucher from LuxCSD, for income payments as of 14 December 2020, must send their request to the relevant dedicated email address: adhoc_refunds_portugal@clearstream.com.


The issuance of a tax voucher and amendment of Modelo 30 can be requested by clients who wish to obtain a standard refund of withholding tax directly with the Portuguese tax authorities. The tax voucher is delivered only if the beneficial owner was fully taxed at source (35%). 

The tax voucher is issued by the Portuguese withholding agent, Clearstream Banking AG. It provides evidence that tax was withheld at source for a previous taxable income payment.

Important note: The attestation does not replace the full chain of credit advices and can only be considered as proof of tax withheld at the level of the tax agent only. It cannot be considered as a credit advice of payment from LuxCSD to the client. If required, a Clearstream Banking credit advice must be requested separately.
The amendment of the initially submitted Modelo 30 is a mandatory requirement of the Portuguese Tax Authorities (PTA) to identify the final beneficial owner to be refunded. It will be performed by Clearstream Banking AG upon receipt of the tax voucher request. 

Impact on clients

The full applicable procedure is available under “Market Specifics” in the Market Taxation Guide - Portugal, under the General information - types of securities, deadlines, other market specifics - Portugal - securities held in CBF page.

Note: The delivery of an attestation may take more than 25 calendar days from the date the valid request is received by Clearstream Banking AG.

It is the client’s responsibility to provide a valid and complete request in order to enable Clearstream Banking to process such requests and deliver the attestation accordingly.

It is not guaranteed that the relevant competent authorities will grant entitlement to a client’s tax reclaim.

Clearstream Banking acknowledges the importance of this matter and is responding to client requests as quickly as possible.
