Small Business Tax Filing Deadlines

Tools to help you track deadlines and stay organized

A tax filing deadline is one deadline you never want to miss. For small businesses, there are many taxes and deadlines to keep straight. Three important things to know:
  1. Make sure you have the correct forms – and fill them out correctly. Double-check your numbers.
  2. If you don't have money to pay, go ahead and file your returns by the due dates. You'll sidestep the failure-to-file penalty. If the next deadline comes and you still can't pay, attach Form 9465, an Installment Agreement Request to propose your own monthly payment date and amount.
  3. If you are self-employed, pay the self-employment tax, which includes income tax and social security tax, on these dates:April 15, June 15, September 15 and January 15 of the following year.
