Iowa residents who expect to owe tax of $200 or more for 2021 from income not subject to withholding tax must make estimated tax payments to avoid a penalty for underpayment of estimated tax. For additional information, see IA 1040ES instructions.
Farming or Commercial Fishing
If at least 2/3 of your income is from farming or commercial fishing, you may avoid penalty for underpayment of estimated tax in one of the following ways: (1) You may pay the estimated tax in one payment on or before January 15, 2021, and file your return by June 1, 2021, or (2) you may file your return and pay the tax in full by March 1, 2021.*
Nonresidents with nonwage income from Iowa, see IA 1040ES instructions.
Each individual required to make estimated payments must file an estimated payment under his/her name and Social Security Number.
How to Pay
You can set up your payments to be automatically deducted from your bank or credit union account using ePay (free direct debit) by credit/debit card, in person or by mail. Simply select Individual Income Estimate Tax and the payment option that works best for you using EasyPay Iowa.
