Federal Tax Filing Dates (2018)
On July 18, 2017, the Internal Revenue Service issued final and temporary regulations that updated the due dates and rules for extensions of time to file for certain tax returns and information returns. These regulations are applicable for returns filed on or after July 20, 2017, however, many of the statutory changes were effective December 31, 2015, and those statutory changes supersede these final regulations.
These final regulations reflect the statutory changes of several bills passed by Congress late in 2015 that contained provisions that affect items that aren’t related to the main bill. The “Surface Transportation and Veteran’s Health Care Choice Improvement Act of 2015” and the “Protecting Americans from Tax Hikes Act of 2015” both contained such items.
Whenever a regular tax filing date falls on a Saturday, Sunday, or a legal observed holiday in the District of Columbia, the due date for returns is pushed to the next business day. In 2018, several due dates will be adjusted because of this rule: the Individual and FBAR due date; the C Corporation due date; the Form 1041 due date and extended due date; and the Partnership extended due date.
For calendar year tax returns reporting 2017 information that are due in 2018, the following due dates will apply.
|2018 Filing Due Date (Tax Year 2017)
|Form W-2 (electronic or mail)
|Form 1065 – Partnerships
|Form 1120S – S Corporations
|Form 1040 – Individuals
|FinCEN 114 – FBAR (will be allowed to extend)
|Form 1041 – Trusts and Estates
|Form 1120 – C Corporations
|Form 990 Series – Tax Exempt Org
|Form 5500 Series – Employee Benefit Plan
|Extended Due Dates
|Form 1065 Extended Return
|Form 1120S Extended Return
|Form 1041 Extended Return
|Form 1120 Extended Return
|Form 1040 Extended Return
|FinCEN 114 (Extended with Form 1040)
|Form 990 Series Extended Return
|Form 5500 Series Extended Return
For fiscal year filers:
- Partnership and S Corporation tax returns will be due the 15th day of the third month after the end of their tax year. The filing date for S Corporations is unchanged.
- C Corporation tax returns will be due the 15th day of the fourth month after the end of the tax year. A special rule to defer the due date change for C Corporations with fiscal years that end on June 30 defers the change until December 31, 2025 – a full ten years.
- Employee Benefit Plan tax returns are due the last day of the seventh month after the plan year ends.
It is important to check when tax returns are due for all states in which taxpayers operate, because individual states may not conform to the Federal filing dates.
- Filers of U.S. Return of Partnership Income (Form 1065) will have a longer extension period, a maximum of 6 months, rather than the current 5 month extension, leaving the former (2015 and prior years) extended due date in place (September 15th for calendar year taxpayers.)
- U.S. Income Tax Return for Estates and Trusts (Form 1041) will have a maximum extension of five and a half months, two weeks longer than the former (2015 and prior years) five month extension.
- Annual Return/Report of Employee Benefit Plans will have a maximum automatic extension of three and a half months.
- Report of Foreign Bank and Financial Accounts (FinCEN 114, FBAR) will be due on the same due date as the individual Form 1040 and permitted to extend for six months, thus aligning the FBAR reporting with the individual tax return reporting. Additionally, the IRS may waive the penalty for failure to file a timely extension request for any taxpayer required to file for the first time.
- Filers of Form 990 (series) will now have an automatic 6 month extension period, ending on November 15th for calendar year filers, rather than a 3 month period.
