State sales tax collections were $9 million below projections for August.
August was also the month for the sales-tax-free back-to-school weekend, though the lost sales tax from that weekend would not appear to be the sole cause of the decline. Other state tax revenues, like the franchise tax, were also less than projections.
Revenue has exceeded projections for most of 2013, however.
Continued declines may derail plans for further tax cuts next session.
