The data that self-insurance collects can be used to produce reports.


The Self-Insurance Electronic Data Reporting System (SIEDRS) is a computer system that collects claim information from self-insured employers. All self-insured employers must send this data to L&I at least once a month.

To enroll and use SIEDRS, we must receive a completed SIEDRS Enrollment Form.

The SIEDRS Enrollment Package explains how to prepare your computer systems so that the data can be communicated to us.

SIEDRS Reports

We produce quarterly SIEDRS Reports so that self-insured employers have visibility to industry data.

If you need any older SIEDRS Reports, please send a request to
