Four Types of Penalty
Four types of penalty may be applied to taxes due. In situations where more than one type of penalty applies, the highest percentage penalty is the only one charged
- Failure to timely file a return or deposit: 10%
- Failure to timely pay the tax due on the return or deposit form: 5%
- Audit deficiencies when the Department determines additional tax is due: 5%
- Willful failure to file a return or deposit with intent to evade tax: 75% (There are no exceptions to this penalty.)
Penalty may not be imposed in the following circumstances. The number(s) following each reason indicates which of the three penalties will not be imposed.
- Taxpayer timely pays at least 90% of the correct tax due: 1,2,3
- Taxpayer files a late return or deposit but has 36 immediately prior months of timely filing history (semi-monthly, monthly and quarterly filers only): 1 [This does not apply to income tax filers.]

- Taxpayer proves before being contacted by the Department that the wrong permit holder paid the tax timely: 1, 2

* A taxpayer involved with a self-audit program will receive forms from the Department that will identify the audit as a self-audit program. The specific years will be identified. Any returns voluntarily filed that are not part of the self audit program do not qualify for a waiver of penalty for this exception.

Inheritance Tax Exceptions
Effective for estates with disclaimers filed on or after July 1, 2007, the 10 percent late-filing penalty or the 5 percent failure-to-pay penalty can be waived if the sole reason is a beneficiary’s decision to disclaim property or disclaim an interest in property from the estate.
However, for either penalty to be waived, the Iowa inheritance tax return must be filed and all tax must be paid within the later of nine months from the date of death or 60 days from the delivery or filing date of the disclaimer.
