A personal tax return often asks a seemingly simple question: on how many days did you work, and how many of those were from home? In practice, the answer is not always easy. Calendars, leave, sickness, and personal working days have to be considered together. Anyone looking only at year-end must gather many pieces of information manually.
Some relevant data already exists. Leave and sickness are recorded in everyday work, and personal working days are known. Extending the personal overview gives this information an additional, useful context.
The working year as an overview
For each year, the overview shows how many workdays it theoretically had. From this, days not worked because of leave or sickness are deducted. This creates a traceable view of how many workdays could at most be relevant.
This number is not a tax calculation or a recommendation for what to enter in a tax return. It is preparation help: information that would otherwise need to be found and calculated is available as a personal starting point.
Data gains a new context
The value is not collecting new data. It uses data already present in everyday work for another meaningful question. A leave or sickness entry becomes not only information for team planning but also part of a personal yearly review.
This can be especially helpful when working time or working days changed during the year. Rather than relying on memory, people can see which periods were generally set up as workdays and which were not worked.
The personal conclusion remains personal
What someone derives from this overview for a tax return is their own decision, potentially with tax advice. The overview does not replace tax advice and does not claim which days can be used for tax purposes.
It simply makes part of the necessary preparation less error-prone and less laborious. Data that already exists gains a new meaning without creating another administrative system.
