2021 and all of its tax deadlines are upon us! Below is a quick guide of the most important dates to keep in mind this calendar year.

  • January 15th: due date to pay 4th quarter estimated taxes.
  • February 1st:
    • Due date to send out 1099s and W-2s to recipients.
    • Due date to file 1099-NECs (formerly 1099-MISC using Box 7 for nonemployee compensation) and W-2s/W-3s with the IRS.
  • March 1st: due date to file 1099s/1096s (aside from 1099-NECs) if you are paper filing.
  • March 15th:
    • Due date to file S-Corp (1120S) and partnership (1065) returns

  • April 15th:
    • Due date to file individual (1040), trust (1041), and C-Corp (1120) returns.
    • Last day to make HSA contributions and contributions to the majority of retirement plans.
    • Due date to pay 1st quarter estimated payments.
  • May 17th: due date to file most nonprofit returns (Form 990).
  • June 15th: due date to pay 2nd quarter estimated payments.
  • September 15th:
    • Due date for extended S-Corp and partnership tax returns.
    • Due date to pay 3rd quarter estimated payments.
  • September 30th: due date for extended trust returns.
  • October 15th: due date for extended individual tax returns and C-Corp returns.
  • November 15th: due date to file extended nonprofit returns.

A reminder as regards the April 15th deadline: an extension is an extension to file, not an extension to pay. If you file an extension and still owe money you will be assessed the failure-to-pay penalty of 0.5% per month on the balance. This is a huge improvement over the 5% per month failure-to-file penalty – so by all means file an extension (or get us to file one for you) if you need one.
