I owe state taxes

I owe state taxes for Maryalnd and I am on a payment plan. This year I will get a federal refund will the state take my federal refund? Also my federal refund is higher then what my balance owed is, if they take the federal refund will they send me the differance? Any help would be much appreciated. I have heard many different views of what will or might happen. Thanks!

I am not sure about Maryland as I live in Virginia. But here if you owe state they do take your federal and it doesn't matter if you are on a payment plan or not. If you are due more than owed they will send you the remainder.
