Total Disability Based on Individual Unemployability (TDIU)

Schedular eligibility thresholds

Under the usual schedular rule, one service-connected disability must be rated at 60% or more; or, with multiple service-connected disabilities, at least one must be rated 40% or more and the combined rating must be at least 70%. Certain disabilities may be treated as one for threshold purposes, including conditions from a common cause or affecting one body system. VA must also find that the service-connected conditions prevent substantially gainful work.

Marginal work or work in a protected environment may not count as substantially gainful employment in the same way as regular competitive employment. VA looks at the facts, including earnings, work history, education, and the functional limits from service-connected conditions.

Extraschedular TDIU

If you do not meet the percentage thresholds, VA may still consider referral for extraschedular TDIU under 38 CFR § 4.16(b) when the evidence shows service-connected disabilities prevent substantially gainful employment. This is not automatic and has a separate referral process. It is different from an extraschedular rating for an unusual disability picture under another regulation.

How to apply and what evidence helps

VA generally asks for VA Form 21-8940, which covers employment, education, and when service-connected conditions affected work. VA may also request VA Form 21-4192 from recent employers. Explain how the service-connected conditions—not age or non-service-connected conditions alone—affect the ability to obtain and maintain substantially gainful work.

Useful evidence can include employment and earnings history, attendance or accommodation records, statements from former employers, vocational evidence, and medical records describing work-related limitations. Be accurate about all work, including self-employment, part-time work, and changes in earnings.

VA TDIU and Social Security disability are separate programs with different eligibility rules. If you are also applying for SSA benefits, review its own five-step evaluation and RFC process; a VA rating does not decide an SSA claim.

Common mistakes

• Assuming unemployment alone qualifies for TDIU.
• Leaving gaps or inconsistencies in the work and education history.
• Not explaining how each service-connected condition affects work tasks and reliability.
• Failing to respond to VA requests for employer information.
• Assuming TDIU is the same as a 100% schedular rating.
• Forgetting that a TDIU denial may still have the usual one-year decision-review deadline.
