No, one of the conditions of your installment agreement is that any refund due to you, the IRS
will automatically apply against taxes you owe. Because your refund isn't applied toward your regular
monthly payment, continue making your installment agreement payments as scheduled until you pay
your liability, including accrued penalties and interest, in full. If your refund exceeds your total balance
due on all outstanding liabilities including accruals, and you don't owe certain past-due amounts, such
as federal tax, state tax, a student loan, or child support, you'll receive a refund of the amount over and
above what you owe.
