It’s really not bad if all you do is work regular jobs, even a lot of them. The problem is Americans are shit at reading and math so they don’t understand directions well. Companies benefit from making it seem complicated though.
If you own your own business taxes are a huge pain, because you have to do all the stuff employers do, like payroll taxes.
If you are part of the ~13% that benefit from itemizing on your taxes, it’s also more complicated.
