As local and international tax regulations become more prescriptive, dealing with them in a cross-border context presents you with a significant challenge. The number and complexity of tax investigations conducted by authorities is rapidly escalating and the need for tax adjustments is rising accordingly. Luxembourg being a key jurisdiction in cross-border tax structuring, we understand the tax pressures you face. That is the reason why we endeavour to provide you with innovative and tailor-made solutions.

Whether you are a financial institution, multinational, fund, investor or high net worth individual, CMS Luxembourg Tax team can help you manage tax control cases and deal with tax authorities as well as manage tax litigation cases. The right tax advice can make a material difference to transaction costs and, in some cases, avert serious consequences.

CMS Luxembourg’s Tax lawyers are able to provide advice on a vast range of transactions to both domestic and international clients. As an example we regularly assist our funds department on the tax aspects of the structuring of regulated and unregulated real estate, private equity or debt assets funds.
