The California Board of Equalization announced today that voter-approved sales tax increases will take effect in 13 cities April 1.

In the Bay Area, sales tax rates will go up in San Leandro, Union City, Concord, El Cerrito, Novato and Santa Rosa. Voters approved the tax increases in the November elections.

Voters in a 14th city, Scotts Valley, also approved a tax increase last year, but a previous add-on tax is expiring so the tax rate there will actually decrease to 9 percent from 9.25 percent.

The tax rate in Sonoma County will remain unchanged at 9 percent because the Sonoma Open Space Authority’s district tax ends on March 31 while on April 1, the Sonoma County Agricultural Preservation and Open Space District tax takes effect.
