The State Funding Board projects that Tennessee revenue growth will slow down in the upcoming budget year. Under revenue estimates adopted by the panel this week, the state’s general fund would grow 2.6 percent to 3 percent in the budget year that begins on July 1. That compares with a revised projection for the current budget year’s collections to grow 3.85 percent to 4.2 percent. At the top of the range of the projections, the state’s general fund would grow by $409 million in the current budget year and by $304 million in the next.
