Luxembourg: Standard refund – additional documentation required by the Luxembourg Tax Authorities


Following recent requests by the Luxembourg Tax Authorities (LTA) to obtain additional details about reclaims submitted, Clearstream Banking1 hereby informs its customers of additional documentation required from the final beneficial owners when filing tax reclaims.



a bank statement evidencing the dividend payment to the bank account of the final beneficial owner must be provided for every new reclaim request made to Clearstream Banking. A power of attorney (PoA) must bear a date not older than the year of payment of the dividend. A bank statement or new PoA may also be requested on a case-by-case basis for reclaims already filed, if required by the LTA.


In its recent handling of tax reclaims, the LTA informed customers that the chain of Credit Advices is no longer enough to prove payment of the dividend to the final beneficial owner.

The LTA consider that a bank statement must be provided in addition to the usual reclaim documentation to prove the actual credit of the dividend to the final beneficial owner’s bank account.

It was also specified that the PoAs provided must be dated the year of the distribution of the dividend or year of the reclaim.

Clearstream Banking already received requests on certain refunds under review by the LTA. It is expected that other refund requests pending with the LTA will also need to be completed with additional bank statements or valid PoAs. Each customer concerned will then be informed by SWIFT of the additional documentation to be provided and of the deadline prescribed by the LTA.

For new refunds not yet filed to Clearstream Banking, it is recommended that customers become acquainted with the updated refund procedure described below.
