Did You Know?
With Individual Unemployability, your monthly payment changes to the 100% rate — but your disability rating itself stays exactly where it is.
There is a gap the rating tables do not handle well. A percentage describes a condition in the abstract. It does not describe what happens when that condition ends the only kind of work you know how to do.
Total Disability based on Individual Unemployability — TDIU — exists to close that gap. It pays at the 100% rate when your service-connected conditions keep you from holding substantially gainful employment, even though your combined rating adds up to less.
Do you meet the numbers?
There are two schedular paths, and you only need one:
- One service-connected disability rated at 60% or more, or
- Two or more service-connected disabilities, with at least one rated at 40% or more and a combined rating of 70% or more
VA also notes that in certain cases — for example, if you need to be hospitalized often — you may qualify at a lower rating. That is the extra-schedular path, it is decided case by case, and it is harder to win.
Meeting the numbers is not the same as qualifying
The percentages get you in the door. The claim is decided on whether your conditions actually prevent substantially gainful employment.
What “substantially gainful employment” means
VA is not asking whether you can do anything at all. It is asking whether you can hold a real, sustaining job given your service-connected conditions.
That distinction matters. Marginal or sheltered work — a few hours here and there, or a family business that pays you regardless of what you produce — does not automatically disqualify you. Steady, substantial earnings usually will.
Your education and work history are part of the picture too. A back condition that ends a twenty-year career in the trades is a different case from the same condition in someone who has spent that career at a desk.
The forms
- VA Form 21-8940 — Veteran's Application for Increased Compensation Based on Unemployability. This is the core application.
- VA Form 21-4192 — goes to a recent employer to confirm why your employment ended or changed.
You can file TDIU on its own or alongside a new or increased rating claim.
Evidence that actually carries a TDIU claim
- A work history that shows the pattern — jobs lost, hours cut, or repeated attempts that did not hold, tied to the rated conditions.
- A doctor's statement about functional limitations at work specifically. Not a list of symptoms. What you cannot do for eight hours a day.
- Your own statement describing what a workday looks like now compared to before.
- Vocational rehabilitation records, if you have them, showing retraining or return-to-work attempts that did not succeed because of the condition.
“The strongest TDIU evidence answers one question: what happens when this veteran tries to work a full week, every week?”
Why TDIU claims get denied
- Earnings that look substantial with nothing in the file explaining marginal or sheltered employment
- Medical evidence that describes the condition thoroughly but never connects it to working
- A missing or incomplete 21-4192 from a former employer
- Filing below the schedular thresholds without a real argument for extra-schedular referral
