Intuit Inc. is being questioned by US lawmakers who say federal tax credits the company received could have been better spent to build a free government alternative to its popular online tax preparation software, TurboTax.

“For years, Intuit’s corporate lobbyists have argued that the federal government should not set up a program for Americans to file their taxes online and for free because it would be too costly for taxpayers,” the lawmakers, including Senators Elizabeth Warren and Bernie Sanders, wrote in a letter to the company. “Your company’s disclosure reveals that Intuit’s research tax break from 2022 alone could have been enough to fund a year of a free e-File program for millions of Americans.”
