# How can I add income from abroad?

__If you have received income from abroad, you must:__

* Tick "I have received a salary" and "I received income from abroad" in the "Tax situation" form.
* Add your income in the "Salaries" form and select the "Source" corresponding to this income.

**This income will not be taxed a second time but is taken into account for the calculation of the overall tax rate.**
