Can one use his maaser money to pay for his daughter’s tuition? What about the hasa’ot to and from the school?
Would it make a difference if some are subsidized and he is forced to pay more than the average kid does from that area? Can that extra be taken off of maaser?
One may not use ma’aser money for anything that one is obligated to do, and only for voluntary matters.
Concerning girls’ education, Rav Moshe Feinstein (Iggros Moshe YD II:113) writes that since nowadays the State makes it compulsory to attend school until a certain age, and since if you do not arrange for a suitable Jewish school the child will have to recieve non-Jewish education, the arrangements for a Jewish school are obligatory, and one may not use ma’aser money for this purpose.
The hasa’ot are a part of schooling (one can’t get an education without getting to school), and therefore included in the ruling, even if one has to pay extra.
