Apart from the land related taxes, there were other taxes, such as "Garden tax" from compounds where, among others, plantain, coconut and arecanut palms were grown and irrigated by water from the well. "Tree tax" on trees such as palmyrah, margosa and "iluppai" and "Poll tax" equivalent to a personal tax from each. "Professional tax" was collected from members of each caste or guild and "commercial taxes" consisting of, among others, "stamp duty" on clothes (clothes could not be sold privately and had to have official stamp), "Taraku" or levy on items of food, and "Port and customs duties". Columbuthurai, which connected the Peninsula with the mainland at Poonakari with its boat services, was one of the chief port, and there were customs check posts at the sand passes of Pachilaippalai. Elephants from the southern Sinhalese kingdoms and the Vanni region were brought to Jaffna to be sold to foreign buyers. They were shipped abroad from a bay called Urukathurai, which is now called Kayts—a shortened form of Portuguese "Caes dos elephantess" (Bay of Elephants). Perhaps a peculiarity of Jaffna was the levy of license fee for the cremation of the dead.
