When must every self-insurer file their Annual Report?

The requirement for self-insurers to file their Annual Report on specific dates is crucial for compliance and accountability within California’s workers' compensation framework. The correct timing for filing is March 1 for private self-insurers and October 1 for public self-insurers. These dates ensure that reports are submitted in a timely manner to allow for proper review and regulation by workers' compensation authorities.

Understanding the timing is essential because it aligns with the regulatory obligations designed to ensure that both private and public sector self-insurers are meeting their financial responsibilities and maintaining adequate funds to cover potential claims. By establishing these deadlines, the state can monitor self-insurers more effectively and ensure their ongoing compliance with the law.

The other options present different dates that do not align with the established deadlines for filing Annual Reports, leading to potential confusion and non-compliance if those dates were followed. This highlights the importance of knowing the correct deadlines in order to avoid penalties or lapses in reporting.
