Question regarding taxation for my Marie Curie ESR in Israel

Dear Israeli chapter members,

I wonder if someone can help. I recently won a Marie Curie as PhD Student in Israel, where I have just moved to. As stated in the title of this post, I am really excited to start my project, but I still do not understand clearly how the University is calculating the net of my salary.

In this website someone of you already wrote in the past that it depends on the country of citizenship: I am from Italy, and since I registered officially as Italian abroad, according to our system I should not have to pay taxes back home, but only in Israel.

My question is regarding the fact that the University, in order to calculate the net from the gross amount, does not consider the total as gross, but they subtract ~5k NIS from what I think is supposed to be the gross, and there is no way for me to understand why.

Am I wrong? What I am missing? Living+mobility allowances (corrected by the country coefficient) is not considered our gross salary?

Thank you in advance for any help you might give.

Best, 

Carlotta
