The agency’s duties could easily be expanded to simply sending most Americans a refund or a bill, depending on their income and taxes already paid.There’s a simple explanation: tax prep companies such as H&R Block and Intuit spend millions of dollars each year lobbying Congress to keep the current system in place. And they have good reason to do so: according to IBISWorld, tax prep services is an $11 billion industry in the US. No wonder both firms were able to afford lucrative $6.5 million ad slots during this weekend’s Super Bowl broadcast.
