# 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](https://taxx.lu/en).
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.
