Uh, it's a bit of a tricky question, but I have written a bit on Achaemenid taxation here: https://www.reddit.com/r/AskHistorians/comments/adelmt/how_did_the_persian_government_work_on_a_daytoday/edgdwd3?utm_source=reddit-android

Based on Herodotus and Pseudo-Aristotle it appears Persia proper and the twenty-odd vassal satrapies were taxed in different manners. Satrapies had fixed taxes paid in gold on apparently an arable land basis (which I would think is almost equivalent to a poll tax) in addition to various taxes on property, livestock and commercial activity, plus regional variations.
