Is it already that time of the year again? If you’re wondering why things seem to be moving so fast, that’s because the IRS has changed a few things around, moving a few deadlines closer to the beginning of the year.

We’ve collected all the important small business tax deadlines on this calendar. Here’s to the hard work (numerical and otherwise) it takes to run your own successful business.

January 16, 2017

Deadline for 4th quarter estimated tax payments for 2016.

Who’s it for?
Self-employed individuals or businesses that need to make quarterly tax payments.

February 1, 2017

Deadline to send out W-2 for your employees and 1099s for your contractors, and file to the IRS (either electronically or on paper).

Who’s it for?

Form W-2: If your business has employees, you will need to submit copies of their W-2s to the IRS.

Form 1099: If your business employs independent contractors, you will need to submit copies of their 1099s to the IRS. (Read below for exceptions.) Here’s how to prepare 1099s for your contractors.

  • To determine which form to send, reference this 1099 vs. W-2 calculator.
  • Beginning with 2016 tax returns, the IRS has changed filing deadlines for W-2s and 1099s, combining them into a single deadline earlier in the year.
  • If you’re filing Form 1099-MISC and Box 7 (Nonemployee Compensation) is empty, you may file the return on February 28.

February 28, 2017

Deadline for mailing mail out Forms 1099 to the IRS on paper. (Provided you’re not required to meet the earlier February 1 deadline.)

Who’s it for?

Form 1099: If your business employs independent contractors, you will need to submit copies of their 1099s to the IRS.

March 15, 2017

Deadline for corporate tax returns: Forms 1120, 1120S, and 1065.

Who’s it for?

Form 1120: If you’re a C-corporation, where shareholders are taxed separately from the business.
Form 1120S: If you’re an S-corporation, where shareholders are taxed for profits.
Form 1065: If your business is in a partnership.

  • This is also the final deadline to request a 6-month automatic extension. To do so, you must file Form 7004 and cite an estimated tax.
  • If you want to register your business as an S-corporation beginning in the 2017 calendar year, you must file Form 2553 by this date.
