TDIU, short for Total Disability based on Individual Unemployability, is a VA benefit that pays you at the 100% rate when service-connected disabilities keep you from holding steady, substantially gainful work, even if your combined rating is below 100%. It does not change your rating percentage. It raises your monthly pay.
What is TDIU?
Most VA compensation follows your combined rating. TDIU is the exception: if your service-connected conditions prevent you from keeping a job that can support you, VA can pay you as if you were rated 100%. VA’s TDIU page says your rating stays the same and your monthly compensation increases to the 100% rate. It also says odd jobs, which VA calls marginal employment, do not count as steady work.
Who qualifies for TDIU?
You generally need both of these:
- Work limits caused by service-connected disabilities. They must keep you from securing and keeping substantially gainful employment.
- A qualifying rating. One service-connected disability rated 60% or more, or two or more with at least one rated 40% or more and a combined rating of 70% or more.
If you fall short of the percentages, VA can still consider your case under 38 CFR 4.16(b), the extra-schedular rule. VA’s page says some cases, such as frequent hospitalization, may qualify at a lower rating. This route usually needs stronger evidence.

How much more does TDIU pay?
The gap can be large. These are VA’s 2026 monthly rates for a veteran with no dependents, effective Dec 1, 2025 through Nov 30, 2026.
| Combined rating | Pay at that rating | Pay at the 100% rate (TDIU) | Difference per month |
|---|---|---|---|
| 60% | $1,435.02 | $3,938.58 | $2,503.56 |
| 70% | $1,808.45 | $3,938.58 | $2,130.13 |
At 70%, the difference works out to about $25,562 a year. SSA announced a 3.6% cost-of-living increase for 2027 on Oct 14, 2026, and VA compensation is set to rise by the same percentage on Dec 1, 2026. VA had not published its 2027 table when this article was updated.
How is TDIU different from a 100% schedular rating?
A schedular 100% rating comes from the rating schedule itself. TDIU pays at the same 100% rate, but it rests on your inability to work. The monthly pay is the same for a veteran with the same dependents. Some benefits depend on permanence rather than the rate, and some state benefits are written around a 100% schedular rating, so the two are not always treated alike. Our guide to TDIU vs a 100% schedular rating goes through the differences, and the TDIU vs 100% P&T guide covers permanence.
Can you work while you receive TDIU?
You can, within limits. VA does not treat marginal employment as substantially gainful. Under 38 CFR 4.16(a), that generally means earned income at or below the Census Bureau’s poverty threshold for one person, or work in a protected environment such as a family business on a case-by-case basis. The current figure and the details are in our guide to TDIU income limits.
How do you apply for TDIU?
VA says you apply with VA Form 21-8940 and employment information on VA Form 21-4192, and you must already have a service-connected disability. Evidence such as medical records and a doctor’s statement about your work limits supports the request. You do not need to pay anyone to file.

Frequently asked questions
Is TDIU the same as a 100% disability rating?
No. TDIU pays at the 100% rate but is not a 100% schedular rating, because it rests on your inability to work rather than on the rating schedule. VA says your rating percentage stays the same and your pay rises to the 100% rate. Some benefits and state programs treat the two differently.
Can I get TDIU if my rating is below 70%?
Possibly. A single disability rated 60% or more can meet the standard test. Below the percentages, VA can consider an extra-schedular referral if your service-connected disabilities keep you from working. VA’s page mentions cases such as frequent hospitalization. It takes strong evidence and an accredited representative can advise you.
Does TDIU affect Social Security Disability (SSDI)?
They are separate programs with different rules. Getting one does not automatically qualify you for the other, and VA decides TDIU under its own standards. If you receive SSDI, tell an accredited representative, since records from other agencies can sometimes add context to a claim.
Can TDIU be taken away?
VA can reduce a TDIU rating, but under 38 CFR 3.343(c) it has to show actual employability by clear and convincing evidence. A TDIU rating generally cannot be reduced solely because you started substantially gainful work unless you keep that job for 12 consecutive months. Answer any VA employment questionnaire accurately.
Is TDIU permanent?
Not automatically. TDIU can be considered permanent and total if VA decides your condition is permanent, but that is a separate decision. VA’s 38 CFR 3.340 treats permanence as an impairment reasonably certain to continue for life. Check your decision letter, or ask an accredited representative how VA classified your rating.
