On Tax Day, Elizabeth Warren accuses Intuit of manipulating tax filing

As millions of Americans scramble to file their taxes at the last minute, Senator Elizabeth Warren is asking why it isn't easier to do so for free.

The Democrat from Massachusetts on Monday wrote to the CEO of Intuit, maker of America's most widely used tax software, accusing the company of "unethical and potentially illegal practices that cost American taxpayers billions of dollars."

Warren charges the maker of TurboTax software with lobbying against government efforts to create a truly free tax return option for Americans while sabotaging the public-private partnership that allows some Americans to file taxes without paying, called Free File.
