For example, a sigmoid function (click link for equation). You’d need to mess with the constants to align the function with a range of incomes but the general shape will be the same - a low, almost-zero taxation rate for those who earn the least, rising to a threshold (perhaps even 100%, but a lower value like 75% would probably work as well), giving a high taxation to those who earn the most.
Give it a shot. Let me see an equation.

You think the general population is going to have an easier time understanding the sigmoid function that some simple multiplication and addition?
