One of the most valuable and most misunderstood VA benefits is TDIU. It can pay you at the 100 percent rate even when your combined rating is lower, if your service-connected conditions prevent you from working. This guide explains how to qualify.
What TDIU is
TDIU stands for Total Disability based on Individual Unemployability. It pays at the 100 percent compensation rate, $3,938.58 per month for a single veteran in 2026, even if your combined schedular rating is below 100 percent. The logic: if your service-connected conditions keep you from holding steady work, the VA treats you as totally disabled in the way that matters.
The schedular path (the "70/40 rule")
Under 38 CFR 4.16(a), you can qualify the standard way if you meet these rating thresholds:
- One service-connected disability rated at 60 percent or more, OR
- Two or more service-connected disabilities with a combined rating of 70 percent or more, where at least one is rated 40 percent or more
Meeting the numbers is not automatic approval. You also have to show your conditions prevent substantially gainful employment.
The extraschedular path
If you do not meet those thresholds, you may still qualify through extraschedular TDIU under 38 CFR 4.16(b), where the VA considers whether your specific situation prevents you from working even though your ratings fall below the standard cutoffs. This is a harder case to make and is decided at a higher level.
What "unable to work" means
The question is whether you can secure and follow substantially gainful employment. Key points:
- Marginal employment does not disqualify you. If you earn below the federal poverty threshold, that generally counts as marginal.
- Protected or sheltered work (like a family business that accommodates you) may still allow TDIU.
- Age is not a factor. Under 38 CFR 4.19, the VA cannot deny TDIU based on your age or nearness to retirement.
How to apply
File VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Unemployability). Strong claims show a pattern: jobs tried and lost, hours cut due to symptoms, or a need for constant accommodation, backed by medical evidence and your work history. A focused medical opinion on your functional limits often helps more than a diagnosis alone.
A note on possible changes
As of mid-2026, a TDIU Reform Act has been introduced in Congress that would, among other things, add an age cap for new TDIU recipients. It is not law, and nothing about TDIU has changed yet. Confirm the current rules before relying on them.
A real-world example
A veteran with a 70 percent combined rating, including one condition at 40 percent, had been told 100 percent was off the table because his ratings did not add up to it. He could not hold a job due to his conditions. He applied for TDIU under the 70/40 rule and was paid at the 100 percent rate.
