January 3, 2026 | SIBTF.org — California’s Subsequent Injuries Benefits Trust Fund (SIBTF) is heading toward its most significant overhaul in decades following Governor Gavin Newsom’s veto of Assembly Bill 1329 and a direct mandate for comprehensive reform beginning in 2026.
The veto, issued in October 2025, halted a legislative attempt to recalibrate SIBTF eligibility standards. However, it also set the stage for broader structural changes that state officials now acknowledge can no longer be delayed. With annual SIBTF liabilities projected to exceed $1.5 billion by fiscal year 2029–30, the administration has made clear that the status quo is no longer sustainable.
Why AB 1329 Was Rejected
AB 1329 was introduced as a reform measure intended to curb rising Subsequent Injuries Benefits Trust Fund’s costs. Instead, the Governor concluded that the bill risked expanding eligibility rather than tightening it.
In his veto message, Newsom cited particular concern over language that would have included “activities of daily living” (ADLs) in defining prior disability. According to the administration, this change could have broadened the pool of qualifying claims, accelerating payouts rather than reducing them.
Rather than signing the bill, the Governor opted for a more sweeping solution—one that places responsibility directly on state agencies to redesign the program from the ground up.
DIR and DWC Directed to Deliver a Reform Plan
The veto message formally directed the Department of Industrial Relations (DIR) and the Division of Workers’ Compensation (DWC) to develop a comprehensive Subsequent Injuries Benefits Trust Fund reform proposal as part of the January 2026–27 budget process.
This directive signals a shift away from piecemeal statutory fixes toward a coordinated administrative and fiscal strategy. State officials are now tasked with balancing two competing goals: preserving benefits for legitimately injured workers while preventing systemic abuse and unchecked growth.
What Changes Are Likely in 2026
While final details have not yet been released, multiple policy signals point to several reforms that could take effect as early as 2026:
Stricter Proof of Prior Disability
Claimants may be required to present clearer, contemporaneous medical evidence demonstrating qualifying pre-existing disabilities. Subjective or retroactive documentation may face heightened scrutiny.
Mandatory Neutral QME Evaluations
The state is expected to expand or mandate the use of neutral Qualified Medical Evaluators (QMEs) in SIBTF claims, reducing reliance on competing medical opinions and limiting forum shopping.
A Firm Statute of Limitations
Currently, Subsequent Injuries Benefits Trust Fund claims can surface many years after an industrial injury. A defined filing deadline would significantly alter claim volume and improve long-term financial forecasting.
Together, these measures aim to refocus Subsequent Injuries Benefits Trust Fund on its original purpose—compensating workers whose combined disabilities result in total permanent disability—while restoring fiscal discipline.
Why This Matters for Workers and Employers
For injured workers, 2026 may bring higher evidentiary standards but also greater consistency and predictability in claim outcomes. For employers and insurers, reform could stabilize assessments and reduce uncertainty tied to rapidly escalating fund obligations.
Without intervention, SIBTF’s growth threatens not only the fund itself but also the broader California workers’ compensation system that supports it.

FAQs: About SIBTF Reform in 2026
Why did Governor Newsom veto AB 1329?
The Governor determined that the bill’s language could unintentionally expand eligibility and increase SIBTF liabilities rather than reduce them.
Will SIBTF benefits be eliminated in 2026?
No. Current discussions focus on restructuring eligibility and procedures, not eliminating the program.
When will the new SIBTF rules take effect?
Proposed reforms are expected to be presented with the 2026–27 state budget and could take effect later in 2026.
Will older claims be affected by new rules?
That remains unclear. Any statute of limitations or evidentiary changes would likely include transition provisions.
