Extra Benefits for Workers With Prior Disabilities: Understanding California’s SIBTF Program
What is the Subsequent Injuries Benefits Trust Fund (SIBTF)?
The Subsequent Injuries Benefits Trust Fund (SIBTF) is a special California program that protects workers who already had a disability before their job-related injury.
Under Labor Code sections 4751–4755, SIBTF provides additional compensation when the combined effect of a pre-existing disability and a new work injury leaves a worker more seriously impaired than either condition alone.
This fund ensures you receive
full compensation for your total level of disability, not just the portion caused by your most recent job injury.
Who Qualifies for SIBTF Benefits?
To qualify, your injuries must meet specific criteria established by California law:
- You must have a prior disability or impairment that existed before your work injury.
- Your current work injury must cause permanent disability rated at least 35%.
- The combined effect of your prior and current disabilities must result in at least 70% overall permanent disability.
- You must first settle or resolve your regular workers’ compensation case before applying to the SIBTF.
These claims are highly technical — requiring detailed medical evaluations, rating calculations, and evidence of both disabilities.
Levitz Legal Group helps clients gather and interpret this evidence accurately, using
AI-driven tools to review medical reports and ensure no qualifying condition is missed.
How SIBTF Benefits Work
SIBTF benefits provide additional compensation beyond your regular workers’ comp settlement. For many qualifying workers, the fund pays lifetime weekly benefits that make up the difference between what the employer’s insurer covers and the worker’s total disability value.
For example, a worker who already had partial vision loss in one eye and later loses vision in the other due to a work accident may qualify for ongoing payments from the SIBTF in addition to standard workers’ comp benefits.
In severe cases, such as
traumatic brain injuries or multiple orthopedic impairments, SIBTF benefits can provide crucial long-term financial stability. These payments come from the state-administered trust fund, not from the employer.
How to Apply for SIBTF Benefits
After your main workers’ compensation case is resolved, you can apply directly to the SIBTF through California’s Division of Workers’ Compensation (DWC). The process requires:
- Submitting medical reports and evidence of both your prior and new disabilities.
- Completing and filing an Application for Adjudication of Claim and supporting documentation.
- Attending evaluations or hearings before the Workers’ Compensation Appeals Board (WCAB) if necessary.
Because SIBTF claims involve extensive medical and legal analysis, most workers benefit from attorney guidance.
Levitz Legal Group manages the entire process — from eligibility assessment through filing — ensuring your case is fully supported.

Frequently Asked Questions About SIBTF Benefits
What is the purpose of the SIBTF?
To compensate injured workers whose total disability is greater than what their employer’s insurer covers — ensuring fair, lifetime benefits for combined impairments.
How much can SIBTF pay?
Payments vary based on your combined disability percentage. In many cases, the fund provides ongoing weekly payments for life, supplementing your previous settlement.
Do SIBTF benefits cost my employer extra?
No. SIBTF is a state-administered fund, so your employer’s insurance isn’t charged for these payments.
Do I need a lawyer to file a SIBTF claim?
Yes. These cases are complex and often misunderstood — even by experienced practitioners. Levitz Legal Group identifies qualifying conditions others may miss and handles every step of the application process.
How long do SIBTF claims take?
Because they depend on complete medical and legal documentation, they often take several months or longer. Our firm’s technology-enabled system helps reduce delays and improve accuracy.
