Billionaire tech mogul Elon Musk posted on his social media site that he has “deleted” 18F, a government agency that worked on technology projects such as the IRS's Direct File program.

The IRS is expanding its program that allows people to file their taxes directly with the agency for free.

The IRS will make permanent the free electronic tax return filing system that it experimented with this year.

Florida’s chief financial officer has co-signed a letter with financial officers from 18 states urging the U.S. Treasury secretary and IRS commissioner to “shut down” the IRS Direct File online tax preparation pilot program.

The 12-state Direct File pilot program launched by the IRS in March will potentially serve more than 12 million taxpayers, 2.4 million in Florida alone.
