By Jim Miller, Sacramento Bee | Tax deadline day is Tuesday and the following weeks and months again will make clear that, when it comes income taxes, certain parts of California generate an outsized amount of revenue.
Taxpayers in Los Angeles, Santa Clara, Orange, San Diego and San Francisco counties had the highest total federal tax liability – the amount of taxes owed – in 2014, the most recent data available, according to Internal Revenue Service statistics. In terms of average liability per return, seven Northern California counties – Marin, San Mateo, San Francisco, Santa Clara, Contra Costa, Napa and Alameda – lead the state.
Palo Alto’s 94301 ZIP code, meanwhile, had the highest state adjusted gross income in the 2015 tax year – more than $10 billion – and total state tax liability of almost $1.2 billion, according to Franchise Tax Board statistics. In the Sacramento region, Folsom’s 95630 had the highest adjusted gross income, $3.1 billion, and total state tax liability of almost $158 million.
