Taxation was mandatory in all Spanish colonies during this period, including the Philippines. There were two main reasons the Spanish imposed taxes: to recognize Spain's sovereignty over the colony and to fund efforts to pacify and govern the colony. The main taxes imposed included the tribute (paid by males aged 18-50), sanctorum (for church construction), donativo (for military campaigns), caja de communidad (for public works), and servicio personal (forced labor). Servicio personal required able-bodied individuals to work for a certain number of days each year building infrastructure like bridges and ships.
