So the way laundering works is you have a shit load of money which is black and was earned from illegal sources ( not just tax evasion) just say 1 crore and assume you own or are a partner something like a small business perhaps a sweet shop. ( This is called a front)
What you do is show on the books that you’re earning 1 crore from the sweet shop and then pay taxes and convert the money white.
If it’s from tax evasion the best thing to do is buy property as like 75 percent of the sale is done in black in most parts of India. The white/clean money is only paid for the circle rate.
