You can take a step back to explain this in the "bigger picture" sense.
The US is a for profit country. Virtually everything is done with the intent of making profit, rather than to benefit citizens. This is different than other developed countries, and the reason the US is so rich.
Prisons exist to make money, not to rehab (or punish) inmates.
Higher education exists to make money, not to educate.
"Healthcare" exists to make money, not to heal people.
(The list goes on and on).
Companies spend hundreds of millions of dollars lobbying the government (money is speech, after all) to keep it this way.
So when it comes to filing taxes, the goal is to make money, not to provide a service to citizens that is convenient, easy, free, etc.
