WBSO for startups: keeping the administration in order

Many Dutch tech startups can use the WBSO, the key scheme for research and development work. But getting the application approved isn't enough: without solid hours and project records you lose the benefit at an audit. Here's how the scheme works, which deadlines apply, and where it goes wrong.

What is the WBSO?

The WBSO (the Dutch R&D tax credit) is a fiscal scheme that lowers your research and development costs. For companies with employees it works as a reduction on the payroll tax you remit. For self-employed founders without staff there is a fixed deduction in income tax, provided you spend at least 500 hours a year on qualifying R&D work. You apply at RVO (the Netherlands Enterprise Agency), and on approval you receive an S&O declaration.

When do you qualify?

WBSO doesn't cover all development work. The core requirement: your project must be technically new to your company, with technical uncertainty about whether and how it will work. If you're building a new technical product or solving a technical problem whose outcome isn't a given, you stand a good chance. Routine development, like building a standard website or configuring existing software, doesn't qualify, and RVO has become stricter on software in recent years. Still, for startups doing genuine product development, the WBSO is often the biggest fiscal advantage available.

The administration: what RVO expects from you

The benefit stands or falls with your records, and RVO applies concrete deadlines:

• Hours administration: record R&D hours per project, per person and per day, updated within 10 working days. Reconstructing afterwards is not an option.
• Project administration: document the nature, content and progress of each R&D project, updated no later than two months after the end of each quarter.
• Notification: report the actually realised R&D hours to RVO each year before 31 March.

What happens if it's not in order

RVO audits on a sample basis. If your administration turns out to be incomplete or updated too late, a correction follows on your S&O declaration, and in some cases a fine on top of that correction. The benefit you had on paper evaporates after all.

The trap: application done, administration not

Many startups get the application sorted, often with an advisory firm, and then think they're done. But in the rush of building, the time tracking slips. By the time someone remembers, the 10-working-day window has long passed. The application is the easy part; the ongoing administration is what it really comes down to.

How we handle it

Honest is honest: nobody can take the hour logging and the technical project documentation off your hands. That work sits with you and your team. What we do handle: we process the WBSO credit in your payroll returns, file the annual notification with RVO, and make sure the financial side of your R&D file is correct in your bookkeeping. And we actively remind you of the registration deadlines, so the 10-working-day window and the quarterly deadline never quietly pass. That way the benefit you're entitled to actually stays yours.

In short

• WBSO lowers your R&D costs via payroll tax (or a deduction for the self-employed with at least 500 R&D hours a year).
• Your project must be technically new to your company, with technical uncertainty.
• Deadlines: hours within 10 working days, project records within two months after each quarter, notification before 31 March.
• An RVO audit with poor records means a correction and possibly a fine.
• We process the credit in your payroll, file the notification and guard your deadlines.
