>If other country revenue systems can do this, why do you feel the US tax filing landscape is so different? Because we have 50 states that do everything differently? As other people said, the federal government doesn't even seem to know basic info like if you are married, how many dependent you have, etc etc. If we didn't have any states (or all states used like the same systems that could easily talk to each other) and everything was federal, then yeah it would probably be a piece of cake because all the info is already there. But, we don't.. everything is done differently everywhere, and that affects the taxes.
