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

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

There are some exceptions to these new deadlines. For instance, C corporations that have a tax year that ends on June 30th will maintain their current filing deadline of September 15th, 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.
