With TDIU, you can be paid at the 100 percent rate without a 100 percent rating
If your service-connected disabilities keep you from holding a job, you may be entitled to compensation at the 100 percent rate even though your combined rating is lower than 100 percent. The VA calls this a total disability rating based on individual unemployability, or TDIU.
TDIU exists because the rating schedule deals in averages. A 40 percent rating describes what a condition does to the earning capacity of the average veteran. It says nothing about what your disabilities do to you, given your work history, your training, and your physical and mental limits. TDIU is the rule that closes that gap. A veteran who qualifies for TDIU is paid the same monthly amount as a veteran rated as 100 percent disabled.
The VA decides TDIU in two steps. First it asks whether your ratings are high enough to be considered. Then it asks the question that actually matters: can you work?
Step one: the rating requirements
Under the TDIU regulation, 38 C.F.R. § 4.16(a), you meet the schedular requirements if either of the following is true:
- You have one service-connected disability rated at 60 percent or more; or
- You have two or more service-connected disabilities, at least one of them rated at 40 percent or more, with a combined rating of 70 percent or more.
Meeting these numbers does not win the claim. It only opens the door. Many veterans are surprised to learn that the VA can concede the percentages and still deny TDIU, and that is exactly what usually happens.
When separate ratings count as one disability
The 60 percent and 40 percent thresholds are easier to reach than they look, because the VA treats certain groups of ratings as a single disability for this purpose. Ratings are combined into one when they involve:
- Both arms, or both legs, including the bilateral factor
- Disabilities from a common cause or a single accident
- Disabilities affecting one body system, such as orthopedic, digestive, respiratory, cardiovascular or neuropsychiatric
- Multiple injuries received in combat
- Multiple disabilities incurred as a prisoner of war
This matters more often than veterans realize. Two knees rated 30 percent each, for example, may be treated as one disability rather than two, and that can be the difference between qualifying and not qualifying.
Step two: can you hold a substantially gainful job?
The real question is whether your service-connected disabilities leave you unable to secure or follow a substantially gainful occupation. You do not have to prove you are unable to do anything at all. You have to show you cannot hold the kind of job that supports a person.
The courts have given that phrase real content. A substantially gainful occupation is generally one paying more than the federal poverty threshold for one person, a figure that changes each year. But income is only half of it. The VA also has to look at whether you can realistically get and keep that kind of work, considering your education, your training, your work history, and what your disabilities allow you to do physically and mentally over a full workday and a full workweek.
Marginal employment and sheltered work
Working does not automatically defeat a TDIU claim. Two situations come up constantly:
- Marginal employment. If your earned income falls below the poverty threshold for one person, the work is marginal and does not count against you.
- A protected work environment. If you keep a job only because an employer shields you from the ordinary demands of the labor market, the work may be marginal even if you earn more than the poverty threshold. A family business that carries you, a sheltered workshop, or an employer who tolerates absences and reduced output no competitor would accept can all qualify.
If you are working under conditions like these, say so plainly and document it. A short letter from your supervisor describing the accommodations, the missed days, and the reduced productivity is often worth more than another medical record.
What if you do not meet the percentages
A veteran who cannot work because of service-connected disabilities but falls short of the 60 or 70 percent thresholds is not out of options. Under 38 C.F.R. § 4.16(b), the VA can still award TDIU on an extraschedular basis. Neither the Regional Office nor the Board of Veterans Appeals can grant it directly; the case has to be referred to the Director of Compensation Service. Getting that referral made, and made properly, is frequently where these claims are won or lost.
What the VA is not allowed to consider
Two limits on the VA work in your favor, and adjudicators get them wrong often enough that they are worth knowing.
Your age cannot be counted against you. That is, the VA may not reason that a 68-year-old is out of the workforce because of his age rather than his disabilities.
Conditions that are not service connected cannot be counted against you either. If you have service-connected back and knee disabilities and a non-service-connected heart condition, the only question is whether the back and knees alone would keep you from working. It is not an answer for the VA to say your unemployability is caused by the heart condition, and it is not an answer to say it results from the combined effect of everything together.
How to raise TDIU
The formal application is VA Form 21-8940, the Veteran’s Application for Increased Compensation Based on Unemployability. It asks for your employment history for the last five years, your earnings, your education and training, and the disabilities you say prevent you from working. List every service-connected condition that contributes. The VA will usually also send VA Form 21-4192 to your last employer asking about your work and why it ended.
You do not always have to file a separate claim to put TDIU in play. When you file for an increased rating and the evidence shows you cannot work, TDIU becomes part of that claim, and the VA is obligated to decide it. That principle matters most for effective dates: if TDIU was raised by your record years ago and the VA never addressed it, the benefits may reach back further than the VA is telling you. Even so, file the 21-8940 when you can. It is easier than fighting about whether the issue was raised.
Why TDIU claims get denied
Most denials we see fall into a handful of patterns:
- A VA examiner writes that the veteran is capable of sedentary work, with no explanation of what sedentary work the veteran could actually get or keep
- The decision relies on age or non-service-connected conditions, which is not permitted
- The VA treats part-time or accommodated work as proof of employability without looking at whether it is marginal
- The rating decision recites that the schedular requirements are met and then denies the claim in a sentence, without addressing the veteran’s education, training or work history
- The 21-8940 was never returned, and the VA denied without deciding the issue on the evidence it already had
Each of these is answerable. Several are legal errors rather than disagreements about the medicine, which makes them good ground for appeal.
What TDIU is worth
TDIU pays at the 100 percent rate (see our 2026 VA disability rates and calculator), with additional compensation for a spouse, children and dependent parents. Depending on the circumstances, a TDIU award can also open the door to further benefits for you and your family. If your TDIU is found to be permanent and total, those may include education benefits and health coverage for dependents. It can also affect eligibility for special monthly compensation. These are worth asking about rather than assuming.
Talk to a VA accredited attorney
TDIU cases turn on evidence that veterans rarely think to gather: employer statements, personnel records, vocational opinions, and medical opinions that address function over a full workweek rather than a single office visit. We have spent fifty years building those records and challenging denials that ignore them.
