Estimated Tax

Estimated Tax

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
  • Indiana Form ES-40, Estimated Tax Payment

    Did you know that DOR’s online e-services portal DORpay allows individuals to pay their estimated taxes owed to DOR or view their payment history, 24/7? 

    DORpay offers a quick, safe and secure way to submit payments at your convenience. You will receive a confirmation number right away without having to wait for mail to arrive or checks to clear. Avoid penalties by never missing your payment deadline again. 

    To begin, go to the DORpay website at: DORpay.dor.in.gov and select the “Get Started” link under “DORpay: Electronic Tax Payment Service”. On the “Welcome to DORpay” home page, select “Individual Estimated (IT-40ES)”. This will take you to the “Individual Estimated (IT-40ES) Payment” screen.
