The Internal Revenue Service launched a pilot program last year that allows people to file their taxes directly with the federal government for free. This project is known as Direct File and has since expanded to 25 states.

Billionaire Elon Musk posted on his social media site that he had “deleted” 18F, an agency that worked on the IRS’ Direct File program.

Most people who are eligible for tax credits claim them. Direct File—the IRS’s online tool for filing tax returns—could get more eligible filers to claim EITCs and CTCs.
