Describes a situation where someone or something is paying less tax than they should be, often resulting in a lower financial contribution to public services.
Many wealthy individuals are considered undertaxed due to loopholes in the tax system.
Undertaxed → It is formed from "under-" (meaning below or insufficient) and "tax" (from Latin "taxare", meaning to assess or estimate). The word "undertaxed" means being assessed or taxed at a level that is below what is required or expected.
Think of being taxed 'below' ('under-') what is necessary — that's why undertaxed means not paying enough tax.
