Take note of new business return filing due dates

share this article

As you may be aware, there have been several changes in due dates for some federal tax returns, which will be effective for the 2017 filing season or the 2016 tax year for calendar year-end filers. These modifications relate mostly to flow-through entities, including S corporations and partnerships that provide Schedule K-1s (partner’s/shareholder’s share of income, deductions, credits, etc.), containing investment information of partners/shareholders. 

Due dates related to individual tax returns or estimated tax payments will remain the same; however, one new date will take effect next year that affects individuals. 

What does this mean to you? As you gather tax documents for the coming tax season, we have compiled some suggested actions for your consideration to facilitate a smooth process. 

Partnerships (Form 1065) — The due date is moved from April 15 to March 15 or the 15th day of the third month after the year-end.

S Corporation (Form 1120S) — No change, due dates remain March 15, allowing for preparation of Schedule K-1s as they relate to individuals and organizations 

C Corporations (Form 1120) — Due date moved from March 15 to April 15; in most cases, returns will be due on the 15th of the fourth month after the year-end. However, although the due date of these returns has been pushed back a month, we encourage clients to submit the financial information necessary to complete these returns as soon as possible.

Individuals and Businesses — Foreign Bank and Financial Accounts Report (FBAR) (Report 114) — This form is required for individuals and businesses with a financial interest in, or signature authority over, at least one financial account located outside of the United States, and the aggregate value of all foreign financial accounts exceeding $10,000 at any time during the calendar year reported.

This due date change is the most significant for individual taxpayers; forms are now due April 15 rather than June 30. (For 2017 the due date is April 18 because April 15 falls on a Saturday and the Washington D.C. Emancipation Day holiday will be observed on April 17.) However, for the first time, a six-month extension to Oct. 15 will be available.

Please include any and all information related to foreign accounts when submitting your individual, partnership or corporate tax return documentation.


We understand that adjusting to this new system can be overwhelming. We have included a quick reference guide for tax deadlines from the AICPA HERE.
