Tax Reclaim Services


Recover excess withholding tax, reduce operational burden, and improve transparency over your reclaim process

Withholding tax reclaims can represent significant value for investors and financial institutions with cross-border investments. However, reclaim processes are often complex, manual, time-consuming and fragmented across jurisdictions, custodians, tax authorities and documentation requirements.

Unidentified reclaim opportunities, missed deadlines, incomplete documentation, inconsistent follow-up, or lack of visibility can lead to unrecovered tax and inefficient operations. The consequences are not only financial; they may also lead to client dissatisfaction. At the same time, tax authorities increasingly require more rigorous documentation and information reporting.

BDO Luxembourg’s Tax Regulatory Services team helps clients across the full tax reclaim lifecycle, from opportunity identification and technical analysis to filing, tracking, global coordination and follow-up through to repayment or final response.

Our Tax Reclaim Services combine tax technical expertise, operational coordination, technology-enabled tracking and access to the BDO global network.
