Workers’ Compensation - Unit Statistical Information (Unit Stat)

Who Files

All insurers or other entities licensed to and currently writing workers’ compensation in Texas.

Due Date

The first report for a policy is valued 18 months after the effective date of the policy and due 18 to 20 months after the effective date of the policy. For policies with losses, subsequent reports must be valued 12 months after the valuation date of the preceding report and are due by two months after the respective valuation date. Subsequent reports are filed up through the 10th reporting level or until all claims are closed, whichever comes first. Reports are submitted to TDI’s designated statistical agent, NCCI.


Unit Stat is collected and maintained for every workers' compensation policy written in Texas. The data is used in developing job classification relativities, expected loss rates, and discount rates for use by the industry.
