The FICA rate above for California is the social security/medicare tax. An equal portion is paid by the employee and employer. Unemployment is paid by the employer in California. Mortgage tax deductions are a lot more limited since the 2018 tax reforms. Health care is the big wild card since better employers might subsidize 80-100% of the premium while worse one hardly anything. The Obamacare ACA plans can provide subsidized health insurance for lower income workers but the subsidies taper off at a fairly low income given how much you need to survive in California.
