I'd love to see these state-wise as well. Looking at the highest ever federal rate and adding my current california rate would put the total marginal rate at 103%.

It's actually kind of amusing to think about what a marginal rate over 100% would lead to. If the top bracket is $1M+ and you earn $100M, and that last $99M is taxed at 102%, then you owe roughly $101M of your $100M earned, leaving you negative for the year. Better not go above the max! Quick! Donate that $99M in order to maximize your earnings!

Then in future years, make sure to avoid the problem by furloughing all your workers as soon as you hit $1M. Sure, that means both you and your workers only work 1/100 of the year, but what's the point in working longer than that if it earns you nothing?

Yeah, you could also pay your workers a lot more and take less yourself. But in that case you'd spend the whole year working to make what you could make in 1/100 of the year. So again, what's the point?

So I suspect a >100% (or even >90%) marginal tax rate would have a lot of very negative side effects. (Keep in mind that back when the top rate was officially >90%, there were so many loopholes that nobody actually paid that. Closing the loopholes and drastically lowering the top rate was actually revenue-neutral.)

You'd likely have a hard time getting them to come back the next year. Who is going to take a job that pays a normal daily wage but only employs you for three days? And can you really ramp the org back up up in three days? Maybe you'd be better off working for a few days then handing the job off to someone else for the rest of the year. Even then, good luck convincing the board that you're doing anything worthwhile coming in 3 days per year.

I think the equilibrium for this would be fascinating.
