ELI5 what does "doing taxes" in the US exactly mean

except for americans, ive never seen or heard of people. average joes.. from other countries "sitting down" to "do their taxes". where I'm from there are no taxes "to be done".. unless if you have a business in which case you hire an accountant

so what exactly do americans do?

So the real reason people do their taxes is because in the US you usually don't pay the 'correct' amount on each paycheck you receive. You are allowed to essentially determine what the Fed withholds from each paycheck but at the end of the year you can use software to calculate exactly how much you owe. If the Fed had taken more out of your income than you owe, you receive money back. If they took out less, you owe them the difference.

A lot of people have the government withhold a little more than they will owe so that they get a bit back when they file.
