California’s largest companies could find themselves paying an additional $11 billion a year in property taxes under a ballot measure that would dramatically revise the state’s tax-cutting Proposition 13.

Schools and Communities First, a wide-ranging group of community organizations, education advocates, unions and foundations, turned in 860,000 signatures Tuesday that could put that initiative on the November 2020 state ballot.

Under Prop. 13, all California property, residential and commercial, is reassessed only when it is sold. Houses and condominiums, however, can turn over every few years, while many large businesses occupy their land for decades — meaning some have not had property reassessed since Prop. 13 passed 40 years ago.

The proposed ballot measure calls for a split tax roll that would require commercial and industrial property — but not homes and small businesses — to be regularly reassessed and taxed at their full value.
