The US tax filing deadline is extended to July 15, giving Americans an extra three months to turn in their taxes, Treasury Secretary Mnuchin says. Tax day has moved from April 15 to July 15 for both payments and deadlines as the coronavirus pandemic spreads across the country. Treasury Secretary Steve Mnuchin said Friday that "All taxpayers and businesses will have this additional time to file and make payments without interest or penalties." Ref. USAToday.
