US Treasury Secretary Steven Mnuchin arrives to testify during a House Ways and Means Committee hearing about the Fiscal Year 2021 budget request on Capitol Hill in Washington, DC, March 3, 2020.

The Treasury is recommending the Trump administration push back the April 15 tax deadline amid concerns over coronavirus, Treasury Secretary Steven Mnuchin told reporters on Wednesday.

"We are going to recommend to the president that we allow a delay," he said after speaking on Capitol Hill. He appeared before the House Appropriations Committee on Wednesday, where he suggested pushing back the deadline.

"That will have the impact of putting over $200 billion back into the economy and that will create a very big stimulus," Mnuchin said.

The delay would be "for virtually all Americans, not the super-rich, that's our recommendation," he said.

How exactly this delay would unfold was not clear. The IRS referred questions to the Treasury, which did not immediately respond to emails and a phone call.

Individual taxpayers aren't the only ones watching. Owners of small businesses face a deadline next week: March 16 is the tax return deadline for partnerships and S-corporations.

As Treasury secretary, Mnuchin has the authority to push out the deadline for tax filings and payments for up to six months, said Nicole Kaeding, vice president of policy promotion at the National Taxpayers Union Foundation.

In the event of a federal disaster, that authority could extend to up to one year, she said.
