The rough economy is causing tax troubles for North Carolinians. The state is in the midst of a cash flow problem and it is causing a temporary backlog for people waiting on their tax return. Amid the shuffling of state funds to fill a more than three billion dollar budget shortfall, there is a shortage of money to pay those tax returns. State officials said if you are one of the many expecting a state refund, do not worry, you will get it. But instead of taking two weeks, it could take up to six weeks.
