MiA, Gobierno de Aragón

2023

Making tax debts and exam deadlines clear enough to act on

I joined Fractal Strategy as a product designer on MiA, the citizen platform of the Government of Aragón. Two of its areas handled processes with real consequences: a tax debt that grows if you ignore it, and a job application that ends if you miss a date. The information was already there and already correct. It just was not usable. That was the problem I was brought in to solve.

Problem area

Correct information nobody could use

Government writing is built to be legally exact, which is not the same as being clear. People were failing at things that mattered to them, and almost never because they did not care. They could not tell what a status meant, or they never saw a deadline coming until it had already passed.

How we found out

Workshops with citizens, sessions with the teams who run these processes, and watching how people were served at a public office counter.

Where people were getting stuck

Problem 1

Checking your own tax debt meant a phone call or a trip to the office.

Problem 3

A status could be legally correct and still tell you nothing about what it meant for you.

01

Oportunity

Make every legal status readable without a lawyer, a relative, or a phone call.

02

Opportunity

Show what is due and how much time is left, at every step of both processes.

Design goals

What I aimed to achieve

Say it in normal words

Show each legal status in words people already know.

Say it in normal words

Show each legal status in words people already know.

Always show the clock

Make what is due, and how long is left, impossible to miss.

Let people finish alone

No phone call, no office visit, no relative who understands it better.

All of it built inside DESY, the government's design system, which already met the WCAG AA level Spanish law requires of public services.

Design decision 01 · Debts and payments

Making four legal states readable at a glance

Every tax debt sits in one of four legal states, and each one changes what you owe and who is collecting it. For the length of the project I was in the tax department almost every week to get them right. Then I coded them by severity, so the worst news reads before anyone reads a word.

The four states, on one screen

Red once a surcharge has started, black when it leaves for the national agency, grey when it is paused, and no tag at all when there is nothing to worry about yet.

01

Voluntary period

Still inside the deadline, nothing extra to pay.

02

Enforcement period

Deadline passed, a surcharge is added under article 28.2.

03

Moved to the national agency

The debt leaves the regional office for a different organisation entirely.

04

Suspended

Paused, usually because the person asked to split the payment.

When the debt leaves the regional office

State three hands the debt to Spain's national tax agency. Rather than say so and stop, the screen names the department and gives the number to call.

Design decision 02 · Debts and payments

Showing what you owe, by when, and how to pay it

MiA shows a debt but does not collect it. Payment happens at a bank, using an official payment letter, or automatically by direct debit. So the job was not to build a checkout. It was to make sure nobody is left wondering how much they owe, how long they have, or what to do next.

Opening a debt

Four things every debt has to answer

01

Urgency before scrolling

A red banner at the top of the list carries the total overdue amount.

02

The deadline, counted down

Not just a date. The days remaining sit beside it, in red.

03

The money, broken down

Principal, surcharges and total on separate lines, so the number is never a surprise.

04

The document that lets you pay

The official payment letter, ready to download and take to a bank.

All of it, at two sizes

People use MiA at a desk while doing paperwork, and on a phone in the middle of something else. Every state, panel and button had to hold up at both sizes. Neither version is a cut-down of the other.

The same screen, desktop and phone

The same information, in the same order of importance, laid out to fit each screen.

Design decision 03 · Public exams

Showing a months-long process as one timeline

Applying for a public sector job in Spain runs for months: you apply, you wait for the admitted list, you sit up to three exams, then a merit phase, then a final resolution, then the appointment itself. Every stage has its own legal deadline. I worked with the department that runs these exams to map the real sequence, then built one view that holds all of it.

Every stage of one exam, in order

All the exams you are following

Someone can follow several exams at once, each moving at its own pace, without tracking any of it themselves.

Four things every debt has to answer

01

Where am I?

The current stage is marked, everything ahead stays visible.

02

Is anything waiting for me?

Payments and documents appear on the stage that needs them.

03

How long do I have?

Deadlines carry the days remaining, not just a date.

Design decision 04 · Public exams

Turning a rejection into a clear next step

The hardest moment in the process is being provisionally excluded. Your application has a problem and Spanish law gives you a short window to fix it. Miss it and months of preparation are gone. So this screen does three things at once, and keeps the rest of the process in view underneath.

Excluded, with a way back

What the screen shows together

01

Why you were excluded

The exact reasons, in the department's own official wording.

02

How long you have

Ten working days, in red, next to the status.

03

The button that fixes it

Directly under the reasons, not on another page.

And when it goes well

Results arrive with the context that makes them mean something: how many passed, the cutoff mark, and your own.

Validation

Nothing shipped on an assumption

Each area of MiA went through its own research cycle rather than one study at the start. For debts and public exams that meant sessions with the departments that own each process, then testing prototypes with real people while the design was still changeable, and again before release.

Testing sessions

Prototypes were put in front of real users while the design could still change, not after it shipped.

Where people were getting stuck

A cycle per area

Each new area got its own research, not one study reused across all of them.

Retrospective

Designing for people who did not choose to be here

Nobody opens a government debt page for fun, and nobody enjoys tracking an exam application. When someone is dealing with money they owe or a job they might lose, design is not about delight. It is about removing every reason to give up before the task is done.

The departments could tell me what was legally true. Deciding what a worried person needed to see first was still my job.

A phone call became a screen
