Describing something that is against or opposed to taxes.
The antitax movement gained support from many citizens who felt overburdened by government fees.
Antitax is formed from "anti-" (meaning against) and "tax" (from Latin "taxare", meaning to assess or evaluate). The word refers to something that is against taxation or tax assessment.
Think of 'anti-' meaning against, and 'tax' meaning to assess — this helps you remember that 'antitax' refers to being against tax assessment.
