Hi Shibam,

Revenue administration in the Mauryan period

The administration of revenue involved collection of taxes from various sources like mines, forests(vana), plantation(setu), pastures(vraja), etc. The cities according to the Arthshaastra, collected 21 kinds of taxes.

Tolls, lines, fees, assaying department for measures and weights, police, passports, currency, manufacturers of yarn, oil, ghee and sugar, slaughter houses, liquor-vends, goldsmiths, warehouses, gambling dens, buildings, prostitutes, guilds of carpenters and artisans and temples were the main sources of revenue in towns.

The chief sources of revenue in provinces were land and agriculture, pastures, traffics in river and road, trade, etc.

I hope this answer helps you.

All The Best!!
