The Associated Press reports Oklahoma finance officials say collections to Oklahoma’s main operating fund exceeded the monthly estimate by nearly 20 percent, a jump attributed largely to continued economic recovery.

The gross production tax on oil generated $34 million last month, nearly 130 percent above the estimate. Tax collections for individual and corporate income, sales and motor vehicles all exceeded both the estimate and prior year collections.

State officials expect a “robust” deposit into the state’s Rainy Day Fund.
