Many IRS filing deadlines have recently been changed by Congress, in H.R. 3236, the Surface Transportation and Veterans Health Care Choice Improvement Act of 2015.

Effective as of December 31, 2015, if you are required to file with the IRS for your C corporation, partnership, or FBARs, then your due dates have likely changed.

Partnerships have a new deadline of March 15^th, whereas filings for C corporations and FBARs will be due on or before April 15^th. FBARS also now have a 6-month extension, ending October 15^th.

For others that are required to file a tax return with the IRS, the due date is still April 15^th, and for S Corporations the due date still remains March 15^th.

There are some exceptions to these new deadlines. For instance, C corporations that have a tax year that ends on June 30^th will maintain their current filing deadline of September 15^th, with the new deadline applying only to returns for taxable years beginning after December 31, 2025.

Check with your tax professional to find out your filing due date.
