Papal taxes, begun in the 12th century, required Catholic clergy to pay one-fortieth of their income to support the crusaders. The practice was continued by later popes. Originally, the taxes went directly to the crusaders. 
In the 13th century, the collection of taxes supported crusades outside the Holy Land, such as Pope Gregory IX’s war against Frederick II, the Holy Roman Emperor. The taxes went straight to the pope to distribute as he saw fit, or in some cases, to a nobleman who promised to go on crusade.
During the 14th and 15th centuries, papal taxes were used for wars against the Ottoman Turks and others. Next time you pay income taxes, remember that it’s not a new institution, and nothing much has changed. Working citizens still have to pay, and don’t have much to say about how the governing body spends it.
