TDIU: The 100% Rate When Work Isn’t Possible

TDIU is short for total disability based on individual unemployability. The VA can pay it when service-connected conditions keep you from getting or holding a substantially gainful job and your ratings meet one of two thresholds:

• One service-connected condition rated 60% or higher.
• Two or more service-connected conditions that combine to 70% or higher, with at least one of them rated 40% or higher.

When checking that 60% or 40% mark, some groups of conditions count as one disability: conditions of one or both arms, or of one or both legs; conditions from a common cause or a single accident; conditions in the same body system, such as orthopedic or cardiovascular; multiple combat injuries; and multiple disabilities from time as a prisoner of war.

For example, a back condition rated 40% and nerve damage down one leg from that same back, also rated 40%, combine to 60%. Because they share a cause, they can count as a single 60% disability, which meets the first threshold by itself.

Only service-connected conditions count toward the question of whether you can work. The VA sets aside age and any conditions unrelated to service.

VA policy is that every veteran who can't work because of service-connected conditions should be rated totally disabled. When the percentages in 4.16(a) aren't met, the regional office can send the case to the Director of Compensation Service for what's called extraschedular consideration, along with a full picture of your conditions, work history and education. VA.gov points to frequent hospitalization as one situation where this can apply.

These requests need especially detailed evidence. Treating providers should describe specific limits, and an opinion from a vocational expert on which jobs, if any, are still realistic for you gives the reviewer something concrete to weigh.

The test is substantially gainful employment, meaning work that actually supports you. Marginal employment doesn't count against you, and the regulation describes it two ways:

• Low earnings. Earned annual income at or below the Census Bureau's poverty threshold for one person is generally treated as marginal.
• A protected setting. Work can be marginal even when it pays more, if it happens somewhere that bends around your limits. A family business and a sheltered workshop are the examples the rule gives.

The VA also looks at the kind of work you did and why your last job ended. Picture a veteran who helps on a relative's farm a few hours a week when their back allows, with no set schedule and pay that has little to do with output. Those facts belong in the application in writing, from the veteran and from the relative.

Your rating number stays where it is, and the VA pays you at the 100% rate instead. At 2026 rates (effective December 1, 2025), that is $3,938.58 a month for a veteran alone, $4,158.17 with a spouse, and $4,318.99 with a spouse and one child.

For comparison, a veteran alone rated 70% receives $1,808.45. TDIU would add $2,130.13 a month.

If the VA also finds the TDIU permanent and total, dependents may qualify for Chapter 35 education benefits, and some families qualify for CHAMPVA health coverage. Run your own numbers, dependents included, in the VA disability calculator.

• VA Form 21-8940 is the application itself. It asks which service-connected conditions keep you from working, the jobs you've held, what you earned, when you last worked full time and how much schooling you have.
• VA Form 21-4192 goes to your recent employers, who fill it out to confirm dates, duties, earnings and why the job ended. Sending it to them yourself can keep it from stalling.
• Medical opinions should address function: how long you can sit, stand or concentrate, how many days a month you'd miss, and what your medications do to alertness. Diagnoses alone don't answer the work question.
• A former supervisor describing accommodations, warnings or a firing tied to your conditions is strong evidence.
• Social Security disability records help if you have them. Social Security uses different rules, but its file often holds useful medical and vocational evidence.

TDIU builds on conditions that are already service connected. If yours aren't yet, those claims come first or go in alongside it. Conditions that have worsened may be worth an increase claim at the same time.

The VA may send VA Form 21-4140, an employment questionnaire, to confirm you still aren't working a gainful job. Return it on time and answer it honestly.

Taking a job doesn't end TDIU overnight. Under 38 CFR 3.343(c), the VA can't reduce it just because you started substantially gainful work unless you keep that work for 12 straight months. Otherwise, a reduction requires clear and convincing evidence that you can actually work, and the VA has to propose it in writing and give you 60 days to respond. Joining a vocational rehabilitation program doesn't end it by itself either. In Wisconsin, VA lists Veteran Readiness and Employment offices in Eau Claire, Green Bay, Madison and at the Milwaukee regional office; check VA.gov for how each one is meeting with veterans right now.
