That’s correct, Canton may (does) vary
Almost 2 years have passed and I guess you have an answer by now. Are you able to deduct Private School cost from Income?
In VD I understand it is only possible to deduct “frais de garde” which is only in KG. Already at the age of 3 and in a Private school, when they start pre-school, it is no longer deductible unfortunately.
I got the full ~10K deduction IIRC. But I spend more than that with just Betreuung and Essen, i.e., without counting the Schulgeld (OMG!), so maybe that’s why they accepted it?
Just a short insight. I went through public school, did an apprenticeship for 3 years (with vocational baccalaureate) then did the Passerelle (1 year Gym equivalent) and went to Uni to study (with 19). Had a great time ;)…and still friends from many different stages. So in Switzerland, the system is quite flexible.
