The institute of indirect taxation is a place where people learn about things in the government that deal with money. You know how when you want to buy something at the store, you have to pay some extra money on top of the price of the thing you want? That extra money is called a tax.
An indirect tax is one that is added onto things we buy or things we use, like gas for a car or a toy we buy at the store. These taxes help the government pay for things like building roads, schools, and hospitals.
At the institute of indirect taxation, people learn how these taxes work and how they affect the things we buy. They also learn how the government collects these taxes and how they decide how much they should be.
So, to sum it up, the institute of indirect taxation is a place where people learn about special kinds of taxes that are added onto things we buy or use, and how the government uses that money to help make life better for everyone.
