TDIU: When Service-Connected Disabilities Prevent Work

Understand What TDIU Changes

Total disability based on individual unemployability, commonly called TDIU or IU, can provide compensation at the 100% level when service-connected disabilities prevent substantially gainful employment. The underlying disability percentages do not automatically become 100%.

The question goes beyond whether you currently have a job. Explain how the service-connected conditions affect your ability to obtain and maintain work that provides a livelihood. A retirement date or an unsuccessful job search alone does not describe that limitation. Connect the medical and practical evidence to the work you can and cannot reliably perform.

Check the Percentage Routes Without Stopping There

The usual percentage route requires one service-connected disability rated at least 60%, or multiple disabilities with one rated at least 40% and a combined evaluation of at least 70%. Certain disabilities can count together as one for these threshold purposes, including qualifying conditions from a common cause. The detailed rule matters.

Meeting those percentages does not itself prove unemployability. Conversely, being below them does not end the inquiry: the regulation provides a referral route for consideration when service-connected disabilities prevent substantially gainful employment despite lower ratings. Ask how your actual evaluations and work evidence fit the rule.

Explain Income and the Actual Work Setting

Marginal employment generally is not substantially gainful employment. The regulation refers to the Census poverty threshold for one person when assessing earned annual income, and it also permits a facts-based finding of marginal employment above that threshold, including qualifying protected work environments.

Do not substitute a fixed internet dollar figure, household poverty guideline, or simple part-time label for that analysis. Working for relatives, having flexible hours, or receiving accommodations does not automatically settle the issue. Describe what work you actually do, what is excused, what help you receive, and why the job continues despite your limitations.

Build an Employment and Function Record

Prepare a dated work history showing duties, hours, earnings, absences, changes in responsibility, and why each job ended. Include education and training so the record does not examine only your last job title. Keep evidence of unsuccessful work attempts and explain discrepancies between payroll records and the hours you actually worked.

Medical evidence is most useful when it explains functional limitations, such as interrupted concentration, unreliable attendance, difficulty interacting, or restrictions on physical tasks. Include only limitations that are true for you. Separate what a clinician assessed from your own observations and an employer’s account.

• List employers, dates, duties, hours, and reasons for leaving.
• Collect earnings records and relevant workplace correspondence.
• Describe concessions with concrete examples, not just the word protected.
• Identify the service-connected conditions responsible for each work limitation.

Complete the Application and Employer Information

VA’s instructions identify the unemployability application, VA Form 21-8940, and employment-information form, VA Form 21-4192. Follow the current instructions and provide the requested work and education history accurately. Coordinate employer information, while keeping your own copies and documenting attempts to obtain missing material.

If an employer no longer exists or will not respond, tell VA what happened and identify other available records. Do not fill gaps with invented employer statements. A VA-accredited representative can help explain an incomplete employment record and distinguish an IU request from another type of rating claim.

Respond to Employment Questions After an Award

Keep your earnings and work records after an IU award. VA matches wage information with Social Security data and can ask for employment verification when earnings or other evidence suggest gainful employment. Its current instructions call for a response within 65 days of the mailed notice.

This is not a universal instruction to send an employment questionnaire every year without a request. Read the notice and explain the actual work circumstances, including any relevant marginal or protected-employment facts. If work changes, seek guidance on the reporting and benefit consequences rather than assuming that any income automatically ends IU or can safely be ignored.
