Iowa, IRS Late Filing, Tax Payment Penalties
- Failure to Timely File a Return: If you do not file your tax return by the due date and have paid less than 90% of the correct amount, you will owe an additional 5% of the unpaid balance.
- Failure to Timely Pay the Tax Due: If you submit your return in a timely manner but paid less than 90% of the correct tax due, you will be subject to an additional 5% penalty on the unpaid tax. Taxpayers should be aware that they may be subject to both the 5% failure-to-file penalty and the 5% failure-to-pay penalty.
- Audit or Examination Deficiency: A 5% penalty will be applied to the outstanding tax if the Department finds an underpayment during an audit or examination.
- Penalty for Failure to File after Demand: If a taxpayer does not file within 90 days of the Department sending a demand letter, they will be subject to a $1,000 penalty. For every unfiled return mentioned in the demand letter, a different penalty will be applied. This penalty is on top of the previously mentioned penalties for failing to file.
- Underpayment of Estimated Tax: A penalty is imposed for underpayment of estimated tax. This penalty is calculated on Form IA 2220. Generally, if you pay at least 90% of your tax liability by the original due date, certain late filing and late payment penalties may be waived.
- Civil Penalty: A $500 civil penalty is assessed when a return is considered "frivolous," meaning it lacks sufficient information to determine tax liability or contains substantially incorrect information.
- IRS Penalties: Calculate and estimate your potential IRS income tax return penalties.
