Iowa Underpayment of Estimated Tax
How much is the Iowa underpayment of estimated tax penalty?
If you are an individual taxpayer, other than a qualifying farmer or fisher, you may use this form to determine whether your income tax was sufficiently paid throughout the year by withholding or estimated payments. If payments were not sufficient, you may owe a penalty.
Estimated payments are credited to only one individual. Each individual required to make estimated payments must file an estimated payment under his/her name and Social Security Number. The IA 2210 penalty must also be calculated separately by each individual for filing status 3 (married filing separately on a combined return) and filing status 4 (married filing separate returns).
