Problem

Every year, millions of citizens face the Belastingdienst with the same feeling: dread. Letters arrive in formal, legal Dutch, deadlines stay unclear, and the portal expects you to already know the rules. For the elderly, non-native speakers, or the recently bereaved, one letter could mean weeks of anxiety.

The real challenge was trust. Citizens didn't need more information. They needed to feel guided and in control, in a process that had always made them feel small.

Help bereaved citizens understand and complete the required tax and allowance actions after the death of a partner or cohabitant, without adding confusion or increasing the risk of making mistakes.

01

Legal language

Legal language

The Belastingdienst wrote letters to stay legally compliant, not to be understood. Citizens couldn't tell what to do next.

High stakes, low reassurance. Get one field wrong, and it felt like a fine was next.

Research

I based this on 20 internal and external reports and 10 interviews with bereaved citizens. One pattern held across all of them. Fear was the bigger barrier than the tax rules themselves.

That finding reframed the whole project. I mapped every moment of doubt across the journey, prioritised the three that caused the most stress and validated each redesign with the same group of users before moving on.

Find the exact moments where citizens lose confidence. Then design for the emotion, not just the task.

Approach

I rebuilt the experience around three principles: filter, relate, reassure. Strip the page to the one thing that matters now. Speak in plain, human language. Always show what happens next.

// PRINCIPLES

01

Filter

Filter

One task per screen. Everything irrelevant to right now is hidden until it matters.

In testing, the redesign measurably reduced citizen stress and increased task completion. The same people who once dreaded a tax letter now were able to get through the required actions confidently.

Reflection

Reflection

Designing for a government service taught me that empathy is an interface decision. The biggest wins came from removing fear, not new features: a clearer sentence, a visible next step or a moment of reassurance at exactly the right time.

The question you're given at the start is rarely the one you should be answering. The brief asked for a clearer process. The real problem was trust. Once I reframed it that way, the screens followed almost on their own.
