Sales taxes for January came in at $130.3 million, $2.3 million below projections.
Because the January tax receipts are based on December retail sales, Muchow said that figure reflects a weak Christmas shopping season statewide and nationally.
"Christmas activity was a little on the disappointing side," he said. "I think that's reflected in these numbers -- sales were pretty flat."
A 2011 tax credit on hybrid or alternative-fuel vehicles continues to hurt collections of the personal income tax, Muchow said.
The credit -- which was repealed, effective last April 14 -- is expected, ultimately, to cost the state $100 million in income tax payments and continues to cost about $200,000 a month in lost revenue, he said.
There should be about $22 million of the tax credits that will carry over into this year, and Kiss said an unknown figure is how many taxpayers will take first-time alternative-fuel vehicle credits for cars they purchased in April 2013 when they file their 2013 state income tax returns between now and April 15.
Meanwhile, the third-largest tax source -- severance taxes -- came in right on estimate at $33.9 million, and is 28 percent higher than January 2013. Muchow said that's an indication of natural gas sales offsetting a downturn in coal production.
Kiss said the department is continuing to monitor revenue collections to determine if additional spending cuts will be needed before the budget year ends June 30.
"We're going to continue to monitor it, as we're doing for every month this year," he said.
