Line 23 Instructions
Line 23—Overpayment Applied to Estimated Tax
Enter on line 23 the amount, if any, from line 21 you want applied to your estimated tax for next year. Also enter that tax year in the space provided. No interest will be paid on this amount.
If you owe past-due federal or state debts, all or part of your overpayment will be used to pay the past-due amount. You will receive a notice if any of your overpayment has been applied to past-due amounts, so you will know how much was applied to your estimated tax.
You can’t change your election to apply part or all of the overpayment on line 21 to next year's estimated tax.
