IRS Guidelines

  • On Time: Returns are considered to be filed on time and are accepted without penalty if they are properly postmarked and addressed no later than their due date.
  • Extensions: Returns can be extended by filing Form 4868 AND paying 90% of your prior year’s total tax liability by the return’s original due date; e.g. if your total tax was $1,000 in the prior year, you must file Form 4868 and pay at least $900 by the current years due date to avoid penalty.
  • Failure to File: A return filed after the due date and without extension is subject to a Failure to File (FTF) penalty of 5% of the unpaid tax PER MONTH up to 25% of the outstanding liability. Returns more than 60 days late are subject to a minimum FTF penalty of $205 or 100% of the outstanding liability, whichever is less.
  • Failure to Pay: Timely filed returns not paid in full by their due date are penalized at a rate of 0.5% of the outstanding liability per month up to 25% of the unpaid tax.
  • Interest: Interest is charged on unpaid tax at a rate of 3.96% and compounds daily.
