Firm overview

Loyens & Loeff is an internationally based independent full-service law & tax firm having a 100-year track record of international (corporate) tax advisory services with top (international) tax specialists and corporate lawyers, regulatory lawyers and civil-law notaries.

Our tax experts have extensive experience in international taxation in a broad sense, which is more extensive than just the taxation in our four home markets (including EU and OECD tax rules). They translate the developments into their impact on clients' business and are focused on identifying tailor-made solutions. Our international relations with other acknowledged, independent tax advisers and law firms provide for fast and efficient access to high-quality tax or legal advice in countries where we have no office.

In addition to the TP advisory practice on transfer pricing policies of internationally operating clients, the TP team provides integrated solutions on all relevant transfer pricing issues. Their major services include advice on strategy, audits, dispute resolution, documentation and financial transactions.

For state aid issues, which regularly also include TP issues, Loyens & Loeff is very well equipped due to its integrated approach, including a legal approach.
