Total Disability based on Individual Unemployability (TDIU) is a VA benefit for Veterans whose service-connected disabilities prevent them from maintaining substantially gainful employment, even if their combined disability rating is less than 100%. When granted, TDIU pays at the 100% compensation rate, recognizing that some disabilities cause total occupational impairment even when the standard (“schedular”) ratings do not add up to 100%.

What “substantially gainful employment” means

In simple terms, TDIU is about whether your service-connected conditions keep you from holding consistent, reliable work that provides meaningful income. The VA generally distinguishes gainful work from marginal employment (for example, very limited earnings, sheltered/protected work settings, or jobs where major accommodations are required).

What the VA is looking for in a strong TDIU claim

To qualify, you must show that your service-connected conditions—by themselves— make it unrealistic or impossible to secure and follow gainful employment. That usually requires more than a diagnosis. The VA typically wants evidence that clearly explains:

  • Functional limitations (e.g., inability to stand, lift, concentrate, interact with others, maintain attendance, tolerate stress, etc.)

  • Medical support tying those limitations to your service-connected conditions

  • Work history and education (what you’ve done, what you’re trained for, and why those jobs are no longer feasible)

  • Consistency over time (treatment records, symptoms, and credible reports that align with the claim)

  • C&P exam accuracy (because an unfavorable or incomplete exam can heavily influence the decision)

Why TDIU claims are often denied

Many Veterans are denied not because they’re able to work, but because:

  • The evidence doesn’t clearly connect symptoms to work-preventing limitations

  • The VA relies too heavily on a flawed or incomplete C&P exam

  • Key records (treatment notes, employer information, vocational evidence) are missing

  • The claim isn’t framed in a way that matches VA legal standards for employability

How we help

Our firm has extensive experience handling TDIU claims and appeals, including cases involving complex medical conditions, combined impairments, and VA decisions that underestimate the real occupational impact of a disability.

We help Veterans strengthen their case by:

  • Identifying what the VA needs to see to grant TDIU

  • Obtaining and organizing medical documentation and supporting records

  • Developing vocational evidence when it can make the difference

  • Addressing unfavorable findings and challenging inadequate exams

  • Presenting a clear, evidence-based argument consistent with VA regulations

If your TDIU claim has been denied—or if you’re unsure whether you qualify—we can evaluate your situation, explain your options, and fight to secure the benefits you earned through service.
