What Are Supplemental Income Benefits in Texas Workers’ Compensation Cases?
Supplemental Income Benefits — commonly called SIBs — are long‑term wage‑replacement benefits available to injured workers in Texas who suffer serious, lasting impairment and cannot return to work at their pre‑injury earning level.
SIBs are governed by Texas Labor Code §408.142 and §408.143, and they are one of the most misunderstood (and most denied) benefits in the entire workers’ compensation system.
If you have a significant impairment and are struggling to work after your injury, SIBs may be the benefit that keeps you financially afloat — but qualifying is far from easy.
Who Qualifies for Supplemental Income Benefits?
To qualify for SIBs, an injured worker must meet all of the following requirements:
An Impairment Rating of 15% or Higher
You must have received an IR of 15% or more from a designated doctor or from a doctor whose rating has become final.
No Commutation of Impairment Income Benefits (IIBs)
You cannot have taken your impairment benefits as a lump sum.
Reduced Earnings or No Earnings Due to the Work Injury
Evidence must show that your inability to earn your pre‑injury wages is a direct result of your compensable injury.
Active Job Search or Participation in Vocational Rehabilitation
Unless you are medically unable to work, you must:
- Look for work every week, or
- Participate in a DWC‑approved vocational program
Timely Filing of the SIBs Application (DWC‑52)
You must file a DWC‑52 every quarter — on time — or you lose benefits for that quarter.
Missing even one requirement can result in a denial.j
How Long Do Supplemental Income Benefits Last?
SIBs can last for up to 401 weeks (about 7.7 years) after the date of injury.
They are paid in 13‑week quarters, and you must re‑qualify every quarter by filing a new DWC‑52.
How Much Are Supplemental Income Benefits?
SIBs are calculated as:
80% of the difference between your pre‑injury wages and your post‑injury wages
If you have no earnings, you receive the maximum SIBs rate for that quarter.
Why SIBs Are So Often Denied
Insurance companies deny SIBs for reasons such as:
- Claiming your job search was “insufficient”
- Arguing your unemployment is not injury‑related
- Disputing your medical inability to work
- Challenging your impairment rating
- Alleging you failed to document weekly job searches
- Claiming you missed the DWC‑52 deadline
Many denials have nothing to do with the worker’s actual ability to work — they are technical, procedural, or based on paperwork errors.
This is why SIBs are one of the most litigated benefit types in Texas workers’ compensation.
What Counts as a Valid Job Search for SIBs?
The DWC requires an effort to look for work. This may include:
- Applying for jobs
- Attending interviews
- Registering with the Texas Workforce Commission
- Participating in vocational rehabilitation
- Working with a job placement specialist
- Documenting every job contact
If you are medically unable to work, your doctor must clearly explain why, and how your work injury causes that inability to work.

The Bottom Line
Supplemental Income Benefits are designed to help seriously injured workers who cannot return to their old jobs — but the system makes qualifying extremely difficult.
