Do they believe in heaven or hell?
YES. In the “Gathas” Zarathushtra often refers to life after death, and to the “Chinwat Bridge” where the good deeds done on earth are weighed against the evil deeds. Many Zoroastrian scholars believe that the descriptions of heaven and hell in Zoroastrian scriptures are purely allegorical, that heaven and hell are not places but conditions. Some Zoroastrians believe that the reward or punishment for good or bad deeds is often given in this world itself rather than in the next.
