# When is it interesting to file a voluntary tax return?

It is interesting to file a voluntary tax return when you want to:
* recover any overpaid tax if you have paid more than you actually owed
* deduct certain expenses (professional expenses, mortgage interest, insurance, retirement savings, donations, etc.)
* benefit from tax credits you are entitled to
In short, even if you are not required to file, it can allow you to **pay less tax or receive a refund**.
