How can I know whether filing a voluntary tax return is worthwhile for me?

In many cases, it can be beneficial to file a voluntary tax return, especially if you are entitled to a tax refund.

To check this easily, you can complete a free simulation on taxx.lu.

You simply need to provide:

• Your personal details
• Your income
• Your deductible expenses (loan interest, insurance premiums, professional expenses, etc.)

At the end of the simulation, you will receive an estimate of the result of your tax return.

• If the simulation indicates a tax refund, it is worthwhile to file a voluntary tax return.
• If no refund (or only a small amount) is estimated, it is not worthwhile to file a voluntary tax return.

This simulation allows you to make an informed decision quickly and without obligation.
