Local sales tax collections, including New York City’s, increased by 10.5 percent during the first three quarters of 2010, compared to a 9.0 percent decline in the same period the year before. However, over a third of this growth is due to sales tax rate increases and the extension of the sales tax to additional items in New York City and Nassau County. Adjusting for these tax increases, the growth in sales tax collections to date in 2010 has been about 6 percent.
