Tax Regulations for 2018
Fiscal year tax filers have different file dates and extension times.

C corporations have a due date of the 15th day of the fourth month from the end of their tax year. A special rule is in effect for C corporations whose fiscal year has an end date on June 30. For these corporations, the date is deferred to December 31, 2025.
Companies filing Form 1065 - U.S. Return of Partnership income - have a maximum six-month extension period with the extended due date on September 15, the same as former years. Estates and Trusts filing Form 1041 have an increased extension time to five and a half months while Foreign Bank and Financial Accounts (FBAR) have been extended to six months. The filing due date is the same for an individual filing a Form 1040 so the FBAR so that the two are aligned for reporting purposes.
