It depends. If your husband is in the type of installment agreement that provides for the full repayment of federal taxes within 72 months, the IRS will not intercept your state refund. On the other hand, if the taxes won't be repaid within 72 months, the IRS may intercept your state tax refund.
You should speak with a local tax attorney to thoroughly review the details of your husband's installment agreement. Good luck.

The IRS will take your refund on a long-term plan, but will not for some shorter term plans. This language is usually conspicuously stated in the Installment Agreement itself.
As my colleagues stated it depends upon the type of installment agreement.
