Even building fund, if required by the school, should be included. Whether or not the schools charge “ha’adafah” is a matter of debate in this thread (you’ve seen my opinion). Even if they do, since it’s required for admission, it’s an expense I need to pay for my son to learn, so it should be included.
Why ask a shailah – is it nogeia l’ma’aseh? Maybe for ma’aser?
