Q.(See question 2696 above). Do I have to give maaser from the present?
A. Poskim disagree, most maintain that one is not obliged to give maaser from objects one has received as a gift. However, monetary gifts should be included in maaser. (Rabbenu Yonah – Sefer Hayira, Yad Halevi 2: 44, Chazon Ish – Derech Emuna 7: n. 67. Nevertheless, Mishne Halachos 12: 341 and others rule that one must give maaser even on bar mitzva or wedding presents. See question 2432 that one is exempt of giving maaser on money saved).
Horav Shlomo Miller’s Shlit’a opinion is that it depends on how one has accepted from the onset his minhag to give maaser. As mentioned many, times, one should always specify that his maaser is given all b’li neder.
