An individual may make estimated tax payments to reduce the amount that will be due when filing an income tax return. Certain individuals are required to make estimated income tax payments. Those individuals will have an unpaid tax liability that is $1000 or more in any of the following tax types:
- Indiana adjusted gross income tax
- County tax
Payment of estimated taxes
Payment of estimated taxes is due in installments. Due dates are mid-April, June, September, and the January following the last month of the calendar year. If the due date falls on a national or state holiday, Saturday or Sunday, payment postmarked by the day following that holiday or Sunday is considered on time.
Estimated payments can be made by one of the following methods:
- Using a preprinted estimated tax voucher that is issued by the Indiana Department of Revenue (DOR) for taxpayers with a history of paying estimated tax
- Paying online
- Filling out Form ES-40.
You can find your amount due and pay online using the DORpay electronic payment system.
Penalties for underpayment of estimated taxes
You may owe a penalty if:
- You didn't pay any estimated tax,
- You didn't pay enough estimated tax, or
- You didn't make your payments on time.
You may not owe a penalty if you meet an exception to the penalty.
Figure the penalty you owe or show you're exempt from a penalty using form IT-2210.
