In this brief, we review the existing authority of counties to raise the local sales tax, and the viability of this proposed method for offsetting the county revenue losses associated with the proposed property tax shift. As we concluded in our May Revision analysis, the proposals to offset county property tax revenue losses fall short. The revenue likely to be generated from additional local sales taxes—if these taxes are put on the ballot, passed by the voters, and survive likely legal challenges—would offset less than 20 percent of counties’ revenue loss, on average, in 1993-94.
