Taghut is anything in which a servant exceeds the limits whether it is worship, following, or obedience
Fifth question of Fatwa No. 5966
Q 5: When can we single someone out as Taghut?
A: Someone can be declared as Taghut (false god) in case that they call to Shirk (associating others in worship with Allah), to offer `Ibadah (worship) to them, claim knowing matters of Ghayb (Unseen), or judge according to anything other than what Allah has revealed and the like. Ibn Al-Qayyim (may Allah be merciful with him) said: Taghut is anything in which a servant exceeds the limits whether in the field of `Ibadah, following, or obedience.
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family, and Companions!
