Line 10 - Estimated Tax Installment Carryover

This line cannot be changed unless the amended return is filed by the installment payment due date.

Line 11 - Penalty for the Underpayment of Estimated Tax

This penalty is based on the tax that was due by your original filing due date. Any increase or decrease in tax due will change the penalty amount, unless the change is due to a net operating loss carry back deduction. Attach Schedule IT-2210 to support any changes.

Line 17 - Amount Paid on Original Return

Enter the amount of previous payments for individual income tax paid on the original return.

Line 19 - Amount Previously Refunded or Requested

Enter the total of all previous refunds you have received or requested for the year in question.

This amount should be subtracted from your total credits (line 18) to arrive at your net credits (line 20).

Line 21 - Refund

Enter the amount of refund you are claiming. The processing of amended tax returns takes approximately 20 weeks. A claim for refund of withholding credits must be made within two years of the due date of the original return (including extensions). A claim for refund of all other payments and refundable credits must be made within three years from the due date of the original return (including extensions) or the date of overpayment, whichever is later.

Due Date

The due date for filing your Indiana individual income tax return is the 15th day of the fourth month following the close of the tax year. If the due date falls on a weekend or national legal holiday or statewide holiday, the due date will fall on the next business day.

Lines 23 and 24 - Penalty and Interest

If this amended return is submitted after the due date for filing your original return, you must include penalty and interest from the due date. The penalty is 10% of the remittance due or $5.00, whichever is greater.
