TDIU for Veterans — How Individual Unemployability Works in 2026
If your service-connected conditions keep you from holding a job but your combined rating is stuck below 100%, TDIU is the benefit built for you. TDIU — Total Disability based on Individual Unemployability, 38 CFR § 4.16 — pays at the 100% rate: $3,938.58 per month for a single veteran in 2026, more with dependents, even though your schedular rating is below 100%.
A veteran rated 70% who can't work receives the same monthly check as a veteran rated 100% on the schedule. The catch is that TDIU has its own rules — percentage thresholds, an employment standard, and two dedicated forms — and the VA denies a lot of claims on technicalities.
Here's how the whole thing works, veteran to veteran.
What TDIU Is and What It Pays
TDIU compensates you for what your disabilities actually cost you — your ability to earn a living — rather than the percentage math on the rating schedule.
Dependents raise that figure. Whether to chase TDIU or a schedular 100% is its own question — covered in TDIU vs. 100% schedular.
The Two Paths: Schedular and Extraschedular
Schedular TDIU — 38 CFR 4.16(a)
| Scenario | Requirement |
|---|---|
| One service-connected disability | Rated 60% or higher |
| Two or more disabilities | At least one rated 40%+, combined rating 70%+ |
For the "one disability" test, the regulation lets several ratings count as one:
- Disabilities of one or both upper extremities, or one or both lower extremities — including the bilateral factor
- Disabilities from a common etiology or a single accident
- Disabilities affecting a single body system
- Multiple injuries incurred in action
- Multiple disabilities incurred as a prisoner of war
Check your math with the combined rating calculator before assuming you miss the thresholds — the combining rules surprise people in both directions.
Extraschedular TDIU — 38 CFR 4.16(b)
Don't meet the percentages? You're not out. If you can't hold substantially gainful employment because of service-connected disability, the rating activity must refer your case to the Director of Compensation Service for extraschedular consideration. Harder road, but it exists for exactly this situation.
The Unemployability Standard
The test is whether you can secure or follow a "substantially gainful occupation" due to service-connected conditions. Marginal employment doesn't count against you. Marginal means:
- Earned annual income at or below the Census Bureau poverty threshold for one person — roughly $16,000 a year, adjusted annually, or
- Work in a protected environment — a family business or sheltered workshop — even if earnings run higher
Age and non-service-connected conditions may not be considered against you. If the VA's reasoning leans on "he's 68" or "the back is bad but that's not service-connected anyway," that reasoning is legally defective — and appealable.
How to File: Forms 21-8940 and 21-4192
Two forms drive a TDIU claim:
- VA Form 21-8940 — Veteran's Application for Increased Compensation Based on Unemployability. Your employment history, education, earnings, and why you can't work.
- VA Form 21-4192 — Request for Employment Information, sent to each employer from your last year of work.
Incomplete 21-8940s are one of the most common reasons TDIU claims stall. Fill in every employment block, every date range, every earnings figure. Gaps read as evasion to a rater, and the claim sits while the VA sends development letters.
One more thing most veterans don't know: under Rice v. Shinseki, a request for TDIU is part of a claim for increased compensation whenever unemployability evidence is in the record. You can raise TDIU inside an existing claim — you don't need to start a separate one. When the VA ignores that evidence, it's a denial pattern with case law behind it; see the TDIU denial case-law breakdown.
Evidence That Wins TDIU
- Medical opinions that address work impact — not just diagnosis, but what your conditions do to attendance, concentration, lifting, sitting, and reliability
- SSA disability records — a Social Security disability finding is powerful supporting evidence
- Vocational expert assessments — translating medical limits into "no substantially gainful occupation"
- Employer statements — why hours dropped, why accommodations failed, why you were let go
- Work history showing reduced hours, accommodations, or terminations tied to your condition

VetAid reads your decision letter and records against the 38 CFR § 4.16 criteria — the percentage thresholds, the combining rules, the marginal-employment standard — and flags the evidence gaps before the VA does. Free, in under 2 hours.
Check My TDIU Eligibility FreeWhy TDIU Claims Get Denied
- Earnings above the marginal level — income over the poverty threshold without protected-environment facts
- The "sedentary work" opinion — a C&P examiner says you could do desk work without ever addressing your actual work history, education, or skills
- Incomplete forms — the 21-8940 problem above
- No medical link between your service-connected conditions and the unemployability
The "you could do sedentary work" opinion is beatable. An examiner who never asks what you did for a living hasn't evaluated your employability. Answer it with a vocational assessment and your real work history.
Working on TDIU and Permanence
You can work on TDIU — within the marginal-employment line. Income at or below the poverty threshold, or protected-environment work, is allowed. Substantially gainful employment can trigger discontinuance after review, so report honestly and know where the line is. The details live in working while on VA disability.
TDIU is not automatically permanent, but it can be rated permanent and total when your unemployability isn't expected to improve — ending routine re-exams and unlocking the benefits tied to permanent and total status. If your conditions are static, ask for it explicitly.
Frequently Asked Questions
You can hold marginal employment — earned annual income at or below the Census Bureau poverty threshold for one person (roughly $16,000 a year, adjusted annually), or work in a protected environment such as a family business or sheltered workshop even if earnings run higher. What you cannot do is hold substantially gainful employment: if your work rises to that level, the VA can review your case and discontinue TDIU. Report honestly — the standard is unemployability due to service-connected conditions, not total inactivity.
TDIU pays at the 100% disability rate even though your combined schedular rating is below 100%. For 2026, that is $3,938.58 per month for a single veteran with no dependents, and more if you have a spouse, children, or dependent parents. That is the entire point of the benefit: a veteran rated 70% who cannot work because of service-connected conditions receives the same monthly compensation as a veteran rated 100% on the schedule.
Not through the schedular path — 38 CFR 4.16(a) requires either one service-connected disability rated 60% or higher, or two or more disabilities with at least one at 40% and a combined rating of 70% or higher. But 4.16(b) covers everyone else: if your service-connected disability prevents substantially gainful employment and you don't meet the percentages, the rating activity must refer your case to the Director of Compensation Service for extraschedular consideration. It is a harder road, but it exists precisely for veterans below the thresholds.
Not automatically. TDIU can be rated permanent and total when the evidence shows your unemployability is not expected to improve, which ends routine future examinations and unlocks benefits tied to permanent-and-total status. Until then, the VA can review your case — particularly if earnings data shows income above the marginal level — and substantially gainful employment can trigger discontinuance after review. If your conditions are static and you have been unable to work for years, ask for permanent and total status explicitly.
