Total state tax collections as well as collections from two major sources — sales tax and personal income — all declined for the third consecutive quarter. Overall state tax collections in the April-June quarter of 2009, as reported by the Census Bureau, declined by 16.6 percent from the same quarter of the previous year. We have compiled historical data from the Census Bureau Web site going back to 1962. Both nominal and inflation adjusted figures indicate that the second quarter of 2009 marked the largest decline in state tax collections at least since 1963. The same is true for combined state and local tax collections, which declined by 12.2 percent in nominal terms.
