Individual IRS Tax Deadlines in the Calendar Year 2016

As the New Year festivities are drawing to an end, the attention of hundreds of millions of US taxpayers focuses more and more on its annual US tax compliance in the calendar year 2016. In this brief article, I would like to summarize some of the most important deadlines of the calendar year 2016. Obviously, other calendar year 2016 deadlines may also apply to you depending on your situation; please, consult your tax attorney for a detailed review of your US tax requirements.

January 15, 2016: Form 1040-ES for the final installment of estimated tax payments for the tax year 2015.

February 1, 2016: If you did not make your final estimated tax payment by January 15, 2016, you can still avoid the penalty by filing your 2015 US tax return by February 1, 2016.

April 18, 2016: Three important deadlines fall on this date.

First, due to the fact that April 15 falls on Saturday and the following Monday (April 17) is a federal holiday, the US taxpayers will receive a few extra days to file their 2015 individual tax returns by April 18, 2016.

Second, April 18 is also the deadline for the first installment of 2016 estimated tax payments that should be filed with Form 1040-ES.

Third, April 18 is the deadline for filing the automatic 6-month extension to file 2015 income tax return. The extension is done by filing Form 4868 with the IRS. Remember, the estimated tax liability must still be paid by April 18 (i.e. the extension applies to the return filing deadline, not to the actual income tax payment).

June 15, 2016: this is a dual deadline for US individual taxpayers who reside outside of the United States. First, June 15 is the 2015 income tax return filing deadline for such individuals. Second, if these US individual taxpayers do not yet desire to file their 2015 individual income tax returns, then they can file an automatic four-month extension by June 15, 2016. Similar to April 18 extensions, however, the estimated 2015 income tax liability must still be paid by June 15, 2016.

Furthermore, June 15, 2016, is the deadline for the second installment for 2016 estimated tax payments.

June 30, 2016: FinCEN Form 114, commonly known as FBAR (Report of Foreign Bank and Financial Accounts), is due for the calendar year 2016. This is one of the most important international tax deadlines and no extensions are allowed.

September 15, 2016: this is the deadline for the third installment for 2016 estimated tax payments.

October 17, 2016: if the filing extensions to file 2015 individual income tax returns were properly filed, these returns will be due on October 17, 2016 (normally, the deadline would be on October 15, but it falls on a Saturday in the 2016 and the deadline shifts to the following Monday).
