How tax affected i I have wife and child but they are living abroad?

Hi!

I would vey appreciate your advice. Could anyone please help to understand -

I was offered a job in Zurich, now i am considering it and using lohncomputer trying to calculate what will be my net salary. I see that being married and having child affects tax positively - rate comes down.

But if i have wife and 2 years old child, but they will not move together with me in Zurich, they will stay in country we are from, will I still get the lower tax rate? Or it applies only if both wife and child are residents in Zurich with me?

Thank you in advance!
