Voters in different California regions are considering various sales tax measures to address fiscal challenges. 

In Santa Cruz County, Measure E proposes a temporary half-cent sales tax on non-essential goods to mitigate an anticipated $200 million annual loss in local community service funding caused by federal budget reductions. If passed, the tax would fund emergency medical services, mental health treatment, and food assistance. 

Concurrently, several counties including Alameda, Contra Costa, Santa Clara, and San Mateo, along with San Francisco, are considering Senate Bill 63. This regional transit measure would increase sales tax by 0.5% to 1% for 14 years to support public transit agencies. Proponents argue the funds are necessary to prevent significant service cuts, such as potential station closures and major reductions in BART service.

On November 3, voters in five Bay Area counties will decide on the Regional Transit Measure (RTM). The proposal would impose a half-cent sales tax in Alameda, Contra Costa, San Mateo, and Santa Clara counties, and a one-cent sales tax in San Francisco, potentially raising approximately $980 million annually for 14 years. The funds would support agencies including BART, Muni, Caltrain, AC Transit, the Santa Clara Valley Transportation Authority, the San Francisco Bay Ferry, and Golden Gate Transit. 

Proponents state the tax is required to stabilize systems following a post-pandemic ridership slump; BART noted that fare revenue’s share of its operating budget dropped from roughly 71% pre-pandemic to 32% in 2026. Opponents describe the measure as an “avoidable regressive tax” that burdens residents facing high costs of living.
