Why should I still file a tax return even if it is not mandatory?

Even if you are not legally required to file a tax return, it can be financially advantageous to do so.

Filing a tax return allows you to deduct certain expenses or correct the taxation applied during the year. For example:

• loan interest
• insurance premiums (life insurance, liability insurance, health insurance, etc.)
• contributions to a private pension plan.
• donations to recognized organizations
• certain extraordinary expenses (childcare costs, housekeeping fees, etc.)

Without a tax return, these items are not taken into account, which may result in paying more tax than necessary.

In many cases, voluntarily filing a tax return can allow you to receive a tax refund. This can be particularly relevant if you worked only part of the year, if your income has varied, if you have foreign income, or if you have incurred deductible expenses.

In summary, even if you are not obligated to do so, filing a tax return can help optimize your situation and, in some cases, recover a significant amount.
