How tax brackets work, for one. I’ve seen so many bad takes from people who clearly don’t understand them.

A home econ class or hell even a math class could assign everyone some facts about their fictional situation (like a w2, number of kids, house payments, donations, etc) and then have everyone do their taxes for the year.

You’d teach the process. And spend some time looking at the tax table. Learning about standard deduction, learn about turning your taxes in on time…

What kind of taxes are there? When do you pay taxes (after what activity)? Who do you pay them to?

Not just math (which is often just a %, or brackets) to calculate taxes, the entire process.
