If you missed this deadline to file, here are some suggestions on how best to proceed:

  • File as soon as possible – the IRS’ “failure to file” penalty is 5% of tax due for each month that a return is late.
  • If a return is filed more than 60 days late, the minimum penalty is either $210 or 100% of the tax due.
  • There is no penalty for filing after the due date if your business is due a refund.
  • In some instances, a taxpayer filing after the deadline may qualify for penalty relief if there is a good reason for doing so. Please attach an explanation to your return if this is the case.
  • Alternatively, taxpayers who have a history of filing and paying on time often qualify for penalty relief. For more information, see the first-time penalty abatement page on IRS.gov.
