2017 Tax Due Dates for Businesses

IRS Deadlines for Business Tax Forms & Payments

For businesses, tax due dates can vary depending on the type of business entity. Corporations, partnerships, and sole proprietorships often have different deadlines to file their tax returns. It is also important to note the due dates for mailing out certain information forms and paying quarterly estimated taxes.

Here is a list of the important due dates for businesses in 2017 – mark them on your calendar to make sure you don’t miss any IRS deadlines!

January 16, 2017

The 4th quarterly estimated tax payment for businesses and individuals for 2016 is due on this date.

February 1, 2017

Businesses that have employees requiring W-2 forms or have Form 1099’s for other distributions for the 2016 tax year must send these forms to the applicable recipients by this date.

February 28, 2017

Form 1099’s that will be mailed in to the IRS using paper forms must be mailed by this date. (If the forms will be sent electronically, the deadline is March 31, 2017.)

March 15, 2017

For corporations, this is the due date to file tax returns (including Forms 1120, 1120A or 1120S). This is also the due date to file a tax extension using Form 7004. Note that any tax due must still be paid by this date, whether an extension is filed or not.

Business partnerships also need to file by March 15, 2017 using Form 1065. Alternatively, tax extensions can be filed by this date for partnerships by using Form 7004.

April 18, 2017

For sole proprietors and self-employed persons, this is the general due date for individual tax returns. (Though normally on April 15th, the due date is extended until the 18th this year because of the Federal holiday calendar.) This is also the deadline for tax extension requests if an individual cannot file their return on time. However, if taxes are due, they must be paid by this date, even if you file for an extension.

April 18th is also the due date for the 1st quarterly estimated tax payment for 2017 for businesses and individuals. Payments can be made online or through the mail.

June 15, 2017

The 2nd quarterly estimated tax payment for 2017 is due on this date. Mailed payments should have a postmark of June 15th or earlier.

August 15, 2017

Partnerships that obtained a 5-month tax extension must file their 2016 tax return by this date.

September 15, 2017

For corporations that obtained a tax extension earlier this year, this is the deadline to file their 2016 tax return.

The 3rd quarterly estimated tax payment for 2017 is also due by this date.

October 16, 2017

Sole proprietors and self-employed persons that obtained a 5-month tax extension must complete and file their 2016 tax return by this date to avoid late filing penalties.


Remember! It is important to meet all due dates for filing business tax returns, making payments, and sending out IRS-mandated forms. Not adhering to these deadlines can result in costly penalties and interest that begin accumulating from the original due date.

While tax due dates tend to stay the same from year-to-year, they can change. Make sure to check important tax deadlines for your business every year to avoid accidently missing an important due date that could result in penalties from the IRS.
