CalSavers is California's state-run automatic-enrollment Roth IRA program and the largest state retirement mandate in the country. It applies to employers with one or more eligible employees that do not sponsor a qualified retirement plan. The original phased rollout is complete — the final tier for employers with one to four employees closed on December 31, 2025.
Compliance is now an annual cycle rather than a one-time event. Each spring, the state reassesses mandate status using prior-year payroll data reported to the EDD (DE9C filings). Employers identified as newly mandated receive a December 31 registration deadline for that year — the 2026 cohort must register or file an exemption by December 31, 2026. A business that was below the threshold last year can become covered this year, so California employers should confirm their status annually.
Importantly, sponsoring a 401(k) or other qualified plan does not by itself close the loop: the exemption must be registered through the CalSavers employer portal. Owner-only businesses, government entities, and religious and tribal organizations are exempt, and controlled-group rules apply under IRC §414(b)/(c).
Enrolled employees are placed in a Roth IRA at a 5% default contribution rate with automatic escalation. Employers facilitate payroll deductions but do not contribute — one reason many California businesses instead adopt an employer-sponsored plan, where matching contributions, higher limits, and plan-design flexibility are available.
