Corporations generally must file their tax returns on the 15th day of the fourth month following the end of their tax year. This timeline allows businesses adequate time to compile financial information and prepare their returns accurately after the close of their fiscal year.

For most corporations operating on a calendar year basis, this means they need to file their tax returns by April 15 of the following year. If a corporation operates on a fiscal year, they simply apply this rule to their specific fiscal year end.

This filing deadline is set by the Internal Revenue Service and is crucial for ensuring compliance with tax laws. Failing to adhere to this timeline can result in penalties and interest charges on any taxes owed.

The other options presented do not align with the established federal tax return deadlines for corporations, where the last day of February and the 15th day of the third month would not provide corporations with sufficient time to prepare their returns after the fiscal year end, and filing on the first day of the new tax year is not a recognized deadline.
