The short answer is “it depends”. I know that did not exactly answer your question. In 2016 California passed a law that required qualifying employers to provide a retirement program for their employees. If the company does not set up an IRA or other qualifying retirement program, their employees can participate in the CalSavers program.

CalSavers is being implemented over 3 years. The benchmarks are:

• Companies with 100+ employees must be compliant by September 30, 2020
• Companies with 50+ employees must be compliant by June 30, 2021
• Companies with 5+ employees must be compliant by June 30, 2022

If you need to set up a retirement program, we highly suggest you consult your financial planner.
