Happy Tax Day! Sen. Elizabeth Warren thinks you might be getting scammed.

In a letter to Intuit CEO Sasan Goodarzi, Warren, as well as Reps.

Katie Porter and Brad Sherman, laid into the company over its TurboTax tax-filing program's fees.

According to the lawmakers, TurboTax offers products that "scam American taxpayers into paying for services that should be free."

At the core of their concern is the IRS' Free File program

through which TurboTax and other participants were supposed to offer tax preparation services to low-income Americans for free

But the lawmakers described that program "a failure" due to underutilization

and noted that Intuit left the program last year.

According to stats in the letter, the program was intended to serve 70% of Americans,

but as of 2018, it was only serving 3%.
