LEGAL

Calendar-year S corporations generally file federal returns by March 15.

The Claim

An S corporation has an April 15 federal income tax return filing deadline.

The standard deadline stated in the claim is incorrect for calendar-year S corporations. Federal law generally requires an S corporation to file by the 15th day of the third month after its tax year ends—normally March 15 for a calendar-year filer. April 15 can apply to an S corporation with a January 31 fiscal-year end, but that narrow exception does not justify the unqualified statement.
