Taxes were levied on artisans such as potters, sheep herders, weavers, oilmen, shopkeepers, stall owners, brewers and gardeners. Taxes on perishable items such as fish, meat, honey, medicine, fruits and essentials like fuel was as high as 16%. Taxes on salt and minerals were mandatory although the empire did not claim sole ownership of mines, implying that private mineral prospecting and the quarrying business may have been active. The state claimed all such properties whose deceased legal owner had no immediate family to make an inheritance claim. Other miscellaneous taxes included ferry and house taxes. Only Brahmins and their temple institutions were taxed at a lower rate.
