> What do you think are the right words for stuff that e.g. needs to be payed to the government a) to regulate the market
People generally don't pay the government to regulate the market directly.
If you're talking about payment for permit approvals and things like that, most people would call it a fee.
If you're talking about the taxes associated with certain financial transactions or approval to import an item into the country, those are often called duty.
> b) to provide an income to the government?
Taxes.
