ARTICLE XVI Taxation Section 1. The power of taxation shall never be surrendered, suspended or contracted away, except as to securities issued for public purposes pursuant to law.

Exemptions may be altered or repealed except those exempting real or personal property used exclusively for religious, educational or charitable purposes as defined by law and owned by any corporation or association organized or conducted exclusively for one or more of such purposes and not operating for profit.
