If you have an existing installment agreement, you will need to add the additional balances due.
Amount due from existing agreement
Additional balances due that are not reflected in the current amount due should be included on the current Installment Agreement (even if they are included in an existing installment agreement). Enter the amount in the Installment Agreement on the line "Enter any additional balances due that are NOT included in the current amount owed above. " This will carry to line 6 of the Installment Agreement.
Monthly payment amount
If you already have an installment agreement, enter the amount you wish to pay monthly for the total liability amount (all installment agreements plus current amount due). Maximum number of months is 72.

How do I know if the IRS has accepted my Installment Agreement?
When you make an installment agreement through our program, the IRS will generally respond to your request within 30 days of receipt of your request via mail to let you know if it was accepted or rejected. Once approved, an IRS agent may contact you to request your financial records to verify the amounts you have agreed to pay.
