I never filed taxes in 2007 ut received 2008 federal refund but haven't received state refund yet should I be worried?

Many states are having financial problems that slow down the processing of refunds. Also, if you filed near the deadline, it always takes longer because of the large number of people filing.

Your state revenue department probably has a place on their web site or a phone number to check the status of your refund. If you are worried, refer to one of these places.

If you were not required to file in 2007, that should not be a factor. If you were required to file but failed to, that may be a factor.
