TDIU Explained: When a Veteran Can Be Paid at the 100% Rate Without a 100% Rating
Check Your Combined Rating
See whether your current ratings already meet the schedular TDIU thresholds before you build the rest of the claim.

If your service-connected conditions have stopped you holding down a job, there is a benefit that pays at the 100% rate even though your combined rating is lower. It is called Total Disability based on Individual Unemployability, usually shortened to TDIU or IU. It is not a rating in itself. It is a way of being paid as if you were rated 100%, because the rating schedule has not captured what your conditions actually do to your ability to work.
Veterans find this out late. They have been living on a 60% or 70% check for years, unable to keep a job, assuming nothing more was available until the ratings themselves went up. Often the claim they needed was sitting right there.
What TDIU Is, In Plain English
The VA rating schedule is built around average loss of earning capacity. A 70% rating assumes the average person with that condition loses roughly that much earning ability. But averages do not fit everyone. A knee that keeps one veteran out of heavy lifting may keep another out of the only trade they have ever worked.
TDIU is the correction for that. If your service-connected conditions, on their own, prevent you from holding substantially gainful employment, the VA can pay you at the 100% rate. Your underlying ratings do not change. The payment does.
Two things matter from the start. Only service-connected conditions count. A back injury the VA has never connected to service, or age, or a non-service-connected heart condition, cannot be part of the argument, no matter how disabling. And TDIU is about employment, not about how you feel day to day.
The Two Routes To TDIU: Schedular And Extraschedular
The first route is schedular TDIU, and it has rating thresholds. In broad terms, a veteran needs either one service-connected condition rated at 60% or more, or two or more conditions with at least one rated 40% or more and a combined rating of 70% or more. Certain groups of conditions can be treated as a single disability for this purpose, for example disabilities arising from a single accident or affecting a single body system, which sometimes pulls a veteran over the threshold who did not look eligible on paper.
Meeting the threshold does not win the claim. It only means the VA will consider it on the schedular path. You still have to show the conditions prevent substantially gainful work.
The second route is extraschedular TDIU. This is for veterans who cannot meet the percentage thresholds but who genuinely cannot work because of service-connected conditions. These claims are not decided by the regional office alone. They are referred up for extraschedular consideration, and they are harder, because the argument has to explain why the rating schedule does not adequately describe this veteran's situation. Work history matters enormously here. A veteran whose entire employment record is one physically demanding trade, with no transferable office skills, is making a different argument from someone with thirty years at a desk.
What The VA Means By Substantially Gainful Employment
Substantially gainful employment is work that produces income above the federal poverty threshold for one person and is competitive, meaning you are held to the same standard as anyone else in the job.
Marginal employment does not disqualify you. That covers two situations. Income below the poverty threshold is marginal on its face. And work in a protected environment is treated as marginal even if the income is higher: a family business that keeps you on, an employer who tolerates absences and reduced output no one else would be allowed, a job restructured around your limitations.
So working does not automatically end a TDIU claim. What ends it is competitive work at a gainful income. If you are earning because somebody is carrying you, say so plainly and get the employer to confirm it in writing.
The Evidence That Decides A TDIU Claim
These claims turn on employment evidence far more than on medical evidence, and that surprises people.
- Employment history → dates, employers, job duties, hours, earnings, and the reason each job ended. The VA asks for this on its employment form and also asks former employers directly. Vague or inconsistent dates do real damage.
- Treatment records that speak to function → a note saying your PTSD is severe is less useful than one describing missed appointments, panic in crowds, inability to take direction, or days you could not leave the house. Ask your treating providers to record functional limitations, not just symptoms and medication changes.
- Statements from people who watched you try → a supervisor describing the accommodations made for you, a co-worker describing the days you had to be sent home, a spouse describing what happens the evening after a shift. These are evidence, and they carry weight when they are specific and dated rather than general praise.
- Vocational evidence → in harder cases, an opinion from a vocational expert on whether your limitations, combined with your education and work history, leave any realistic employment open to you.
If you want someone to assemble this with you and decide what is missing, that is part of what we do in our TDIU and VA disability claims work.
Why TDIU Claims Get Denied, And What The Denial Letter Tells You
The common reasons repeat themselves. The veteran is still working and the VA treats the income as gainful without examining whether the job is protected. The VA leans on a C&P examiner's line that the veteran is capable of sedentary work, without asking whether this veteran could realistically get and keep sedentary work. Non-service-connected conditions are blamed for the unemployability. Or the employment information is incomplete and the file simply does not show what happened to the veteran's working life.
Read the denial closely. The reasons and bases section tells you which of these it was, and that determines the next step. A missing employer statement points to a supplemental claim with new evidence. A decision that ignored evidence already in the file points to higher-level review. A disagreement about how the law was applied often belongs at the Board. Our page on what to do after a VA claim denial walks through those options in more detail.
How TDIU Sits Alongside Your Combined Rating
TDIU does not replace your ratings. They stay exactly where they are, which matters, because you can continue to pursue increases on individual conditions while receiving TDIU, and because reaching a schedular 100% through the ratings themselves can open doors TDIU does not.
It helps to know where your combined rating actually stands before you argue about thresholds, since VA math is not addition. Our guide to how VA combined ratings work explains the method, and the VA disability calculator will show you the combined figure for the ratings you already hold. That is usually the first thing to check: whether you are over the schedular thresholds already, or whether an increase on one condition would put you there.
