The tax system in the US is complicated, you've got different state taxes as well as the federal, for example if your kids go to a different state for school than you live, add that your partner might work in another state, maybe they have different relief taxes for disasters through the year. It might very well be a feature but it is complicated, and the more activities you have, maybe investments, a small business, multiple jobs. It becomes overwhelming for non accountants.
