WBSO SPECIALIST · SINCE 2004
Peter Klaren — WBSO specialist
Peter Klaren combines fiscal WBSO expertise with the ability to get to grips with technical development problems and translate them into the criteria RVO assesses. The specialist who discusses your project in depth is also the one responsible for the application.
Who is Peter Klaren?

Peter Klaren is a fiscal economist who has been guiding WBSO applications since 2004. My role is not to replace your engineer, but to quickly understand technical development questions and translate them into RVO's assessment framework.
Over the years I have guided applications at the intersection of software, machine building, electronics, energy, materials, chemical processes and production innovation.
I start with your technology, not with the form.
Peter Klaren studied economics at Erasmus University Rotterdam: drs. in economics (1994), as well as the first-year diploma in law (1992) at the same university. He has worked independently as a WBSO specialist since 2004.
Education and years of practice come together at the heart of the profession: translating a company's technology into the criteria RVO uses to assess an application — and back again.
Areas of expertise
Software, SaaS and AI
Assessment and description of programming bottlenecks involving algorithms, scalability, performance, integration and embedded software.
Product development
Mechanical, electronic and multidisciplinary development projects centred on technical bottlenecks and demonstrating a new operating principle.
Process development
Technically new production processes, scaling problems, material behaviour and process control.
Technical scientific research
Explanatory technical research into phenomena that existing knowledge explains insufficiently.
Innovation box
The fiscal translation of R&D (S&O) into a 9% tax rate on qualifying innovation profit.
RVO questions, objections and audits
Support with additional questions from RVO, objections to decisions and audit preparation.
My role in your WBSO application
I first assess where the technical development or research risk actually lies. I then discuss the project with the technical staff and translate their work into a project description that matches the criteria RVO assesses.
I write the application myself and remain involved with any additional questions, statements of realisation and audits. You do not get an account manager, but the specialist who writes your application.
Personally involved: Peter conducts the substantive intake, assesses the WBSO position and is responsible for the project description. Additional technical or fiscal expertise is brought in where needed.
Representative projects I work on

Written and reviewed by Peter
All substantive WBSO pages on this website are written or reviewed by Peter Klaren. The main guides:
How content on this website is reviewed
The substantive WBSO pages are checked against the current RVO handbook, project forms and current policy changes. Where necessary, technical examples are tested against the formal dividing line between regular engineering and R&D (S&O).
Year-dependent amounts and deadlines are updated separately.
Fees: our fees consist of a fixed and a result-dependent component. See the approach for the full picture.
