About Us

TFS is a fully independent advisory firm specialized in providing tax advise to corporations and high-net-worth individuals in the Netherlands.

Our aim is to offer our clients with effective, comprehensive, professional and individually tailored solutions, maximizing shareholder & individual wealth, within the framework of acceptable tax governance.

We are registered members of the Dutch order of tax advisers.


International operating businesses are more and more affected by tax law changes. Moreover, the new international tax framework is increasingly based on transparency, information exchange and real economic substance. Tax management and good tax governance play a vital role in our new international business environment.

We assist our clients in finding an optimal balanced tax structure, with a manageable low risk of jeopardizing business reputation.

We provide tax advise to corporations operating in the Netherlands or corporations operating internationally in- and through the Netherlands. Albeit that our prime focus is the Netherlands, we have no preferred jurisdiction and provide integrated tax planning solutions which may involve different locations.

Our advice is provided with complete independence and as your trusted advisor all client information will be kept confidential.


Our team has extended experience in international tax planning & structuring, setting up businesses, liaising with tax authorities, optimizing the effective overall tax rates of corporations, mitigating tax risks and incorporating good tax governance for our corporate clients.

In addition we advise high net worth individuals and family offices on how best to enhance wealth through an integrated planning approach to income, corporation and estate tax, pensions, wealth transfer taxes, and an evaluation of estate management strategies.

In addition we provide regular tax compliance services such as assisting in tax audits, preparing and filing tax returns and other tax forms.
