This pretty much depends on your income. 

I don’t know what tax system to every single country in the world so you might need to do your own research. But I know that USA has a progressive tax system. 

Which means that rich people (people with higher taxable incomes) higher federal income tax rates.

So if you are not from USA or not live in the USA you may need to do your research on this topic. 

But you need to know the richer you are the more taxes you will pay all around the world.
