TX HB4483

Replaces the existing workers' compensation insurance maintenance tax with a surcharge system for funding the regulation of workers' compensation and workers' compensation insurance in Texas

Sets a combined maximum rate cap of 2.7% of gross premiums for surcharges imposed under the new Chapter 255 and related Labor Code chapters (increased from the previous 0.6% maintenance tax cap)

Allows insurers to recover surcharge costs by either reflecting the surcharge as an expense in required rate filings or by directly charging policyholders

Applies the surcharge to insurance carriers, certified self-insurers, and self-insurance groups (excluding governmental entities), with proceeds deposited to the Texas Department of Insurance operating account

Takes effect January 1, 2026, with the new surcharge system applying only to annual periods beginning on or after that date; prior maintenance taxes remain governed by former law
