Overview
- SB 63 would let Alameda, Contra Costa, San Francisco, San Mateo and Santa Clara place a regional sales tax on the November 2026 ballot to fund transit for 14 years.
- The tax would default to 0.5% across the region, with San Francisco allowed to set a 1% rate to bolster Muni.
- The measure ties access to revenues to agencies demonstrating improved financial efficiency and cost controls.
- Agencies report large operating gaps as emergency aid wanes, with SFMTA projecting roughly $307–$322 million starting in 2026 and BART $350–$400 million annually by 2027.
- Short-term relief remains unresolved, with a previously discussed $750 million state bridge loan not finalized as officials warn of severe service reductions without new funding.
