Company vision

Company vision

On the basis of our specialist areas VAT & real property transfer tax and customs & international trade, we serve large and small clients directly, and also act as a “taxation back office” for other consultants (such as accountancy firms, law firms and notaries). More than 90% of our clients and consultancy are national, but we also offer advice to international companies, and provide them with tax and legal assistance in the Netherlands.

We see the provision of optimum service for our clients as an enjoyable and rewarding challenge, and guarantee that this service will be personal, fast, expert and affordable.


As our client, you have just one contact person who will give your file personal attention and will deal with the subject matter of your questions him/herself. This means that we can always speak to you on the basis of full knowledge of the relevant issues.


Our philosophy is that a consultant must be available at all times, must provide advice of the highest quality, and must work efficiently and effectively.


We take pride in our reliability and fair play, and endeavour to achieve a good relationship with our clients. We also regard it as very important, in the interests of an optimum tax position of our clients, to have a good relationship with the Dutch Tax & Customs Administration (TCA: Belastingdienst). As a result, we have succeeded in obtaining various rulings from the TCA at the national level, a number of which have been laid down in Decisions of the State Secretary of Finance and are now general policy.


Because we are a small-scale, specialist firm, we can offer our services at a highly competitive rate.
