Joost de Leeuw


In 2007, Joost began studying Law at the University of Amsterdam, having previously studied for his Bachelor’s Degree in Russian Language and Culture. Due to his wide variety of interests, Joost has successfully completed Master’s Degrees in both Criminal and Tax Law. In 2015, he completed his studies with a thesis on participation exemption. Joost is an aspiring member of the Nederlandse Orde van Belastingsadviseurs, which means that he closely follows the latest developments in (international) tax law. He also participates in seminars organized by various bodies, such as the Ministry for Finance, the Chamber of Commerce and the University of Lausanne.


After a short period as a journalist and translator, Joost has found his calling in the legal world. With business in his blood, he has always been attracted to entrepreneurship. During his studies, he was struck by the enormous inequality between the tax possibilities for multinationals and those for SMEs. He feels that this is too disruptive to the markets. Therefore, it is Joost’s ambition to make tax benefits accessible to all entrepreneurs. In this area, he is committed at both a policy and client level. After three years with DTS, Joost is currently working as tax manager and is, among other things, responsible for the Asia Desk.


“I find the best thing about my job being that moment when a client realizes just how valuable good tax advice can be. The difference between what a company pays in taxation before and after our advice is often much greater than the profit made through a reorganization or an advertising campaign. Thus, tax advice has also added value in a commercial sense and is indispensable in every business plan.”
As a tax consultant, Joost is never doing the same thing every day, because no client is the same. He advises companies and investors in diverse sectors and countries. Applying the innovation box prior to a tech start-up, for example, is completely different to giving transfer-pricing advice to a food importer, but both are nevertheless in the area of partnership taxation.

Operating your company

Setting up a BV is free of capital tax. However, after a BV has been created:

  • When hiring an employee, you need to pay wage withholding tax and file the statements on a monthly basis;
  • If your company is a VAT entrepreneur, you need to file VAT returns and meet compliance.
    Typically, on a quarterly basis;
  • Per tax book year, you need to file and prepare a Dutch corporate income tax return;
  • You need to prepare the annual accounts of your Dutch BV,  in line with Dutch accounting standards;
  • Moreover, those annual accounts need to be approved by a shareholders’ meeting and filed at the Dutch Chamber of Commerce;
  • If you distribute dividends, you need to file a dividend withholding tax return. Depending on the type of shareholder and percentage of shareholding, you may also need to file Dutch personal income tax for the recipient of the dividend.

We provide corporate compliance and can assist with keeping your company in good standing. Feel free to contact us.
