Total Disability Based on Individual Unemployability lets veterans who cannot work due to service-connected disabilities receive compensation at the 100% rate. Schedular and extraschedular eligibility, the application process, and what the VA actually looks at.
Total Disability Based on Individual Unemployability (TDIU) is a VA benefit that pays veterans at the 100% disability compensation rate even when their combined schedular rating is less than 100%. The legal standard is that the veteran is unable to secure or follow substantially gainful employment due to service-connected disabilities. TDIU is authorized under 38 C.F.R. § 4.16 and processed according to M21-1, Part IV.ii.2.F.
In 2026, the 100% rate is $3,938.58/month for a single veteran with no dependents. TDIU pays this same amount. The difference between a 70% rating ($1,808.45/mo) and TDIU ($3,938.58/mo) is $2,130.13/month or $25,561.56/year.
For the combined rating threshold, the VA considers disabilities arising from a common etiology (same cause) or a single accident as one disability. This means if you have PTSD at 50% and depression at 30%, and both stem from the same traumatic event, the VA may treat them as a single 70% disability for TDIU purposes under 38 C.F.R. § 4.16(a)(2).
If you do not meet the schedular thresholds but your service-connected disabilities still prevent you from working, you may qualify for extraschedular TDIU under 38 C.F.R. § 4.16(b). This requires referral to the VA Director of Compensation Service for consideration. The legal standard is the same: inability to maintain substantially gainful employment.
Extraschedular TDIU is harder to obtain because it requires an additional level of review. However, the VA has a duty to consider TDIU whenever a veteran raises the issue of unemployability during a claim, even informally. Under Rice v. Shinseki, 22 Vet. App. 447 (2009), a TDIU claim is part of any increased rating claim where unemployability is reasonably raised by the record.
The VA defines substantially gainful employment (SGE) as employment that provides an annual income above the federal poverty level. For 2026, the poverty threshold for a single individual is approximately $15,960/year. If your annual earned income is below this threshold, the VA generally considers you unable to maintain SGE.
Submit VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Unemployability). This form asks for your employment history for the past five years, your education level, the date you last worked full-time, and which service-connected disabilities prevent you from working.
The VA may send VA Form 21-4192 (Request for Employment Information) to your current or former employers. This form verifies your employment history, reason for leaving, and any accommodations made. If you are self-employed, provide tax returns and a statement of duties.
The strongest TDIU claims include: medical records documenting the impact of disabilities on work capacity, a vocational assessment from a vocational rehabilitation expert, lay statements from coworkers or supervisors describing functional limitations, and records of job terminations or inability to maintain employment.
The VA will likely schedule a C&P exam specifically addressing employability. The examiner will assess the functional impact of your service-connected disabilities on your ability to perform sedentary and physical work. Under M21-1, Part IV.ii.2.F.2, the examiner must address the combined effect of all service-connected disabilities on employability.
