What is the innovation box?

The innovation box (innovatiebox) is a reduced corporate tax rate of 9% on profit from qualifying innovative work — against the standard 19%. Qualifying activities include software development under the WBSO, patented inventions and other self-developed intangible assets.

WBSO: the gateway

For most SMEs the gateway is the WBSO, the Dutch R&D tax credit. A valid WBSO declaration from RVO confirms that the work counts as research and development. Income from assets developed under that declaration qualifies for the innovation box.

How much it saves

On €100,000 of qualifying innovation profit: 9% against 19% is a €10,000 saving per year. At €300,000 of innovation profit, the saving grows to €30,000 and more.

Practical requirements

  • An active WBSO declaration for the development work.
  • A clear split of costs between innovation work and the rest of the business.
  • IP developed in-house, in the Netherlands.
  • The innovation box election specified in the annual corporate tax return.
