On March 20, 2020, the Treasury Department and the Internal Revenue Service extended the federal income tax filing deadline from April 15th to July 15th. This coincides with the federal tax payment deadline that was extended to July 15th earlier in the week.
This new guidance does not provide a limit on the amount of income tax that can be deferred until July 15th. Previously, there was a $1 million cap for individuals and $10 million for corporations.
