TDIU / Unable to Work

Who qualifies for TDIU

Under 38 CFR 4.16(a), VA looks for both of these:

• A rating threshold. Either one service-connected disability rated at 60% or higher, or two or more service-connected disabilities with at least one rated 40% or higher and a combined rating of 70% or higher.
• Inability to work. Your service-connected conditions, not age or non-service-connected conditions, prevent you from getting or keeping substantially gainful employment.

For the rating threshold, VA can treat disabilities from a common cause or a single accident, or disabilities affecting both arms or both legs, as one disability.

Below the threshold? Under 38 CFR 4.16(b), VA can refer your claim for “extraschedular” TDIU if the evidence shows you cannot work because of your service-connected conditions.

What counts as working

• Substantially gainful employment generally means work that pays above the poverty threshold for one person. Regular full-time work at that level usually rules out TDIU.
• Marginal employment is earnings at or below that threshold. It is allowed.
• A protected work environment can also be marginal employment, even with higher pay. Examples are a family business or a sheltered workshop that makes special accommodations.

Your education, training and work history matter. VA asks whether you can realistically do the kinds of work you are qualified for, given your service-connected limitations.

How to apply for TDIU

1. Complete VA Form 21-8940 (Application for Increased Compensation Based on Unemployability). List your work history for the last five years you worked and your education.
2. Send VA Form 21-4192 to recent employers. It asks them to confirm your dates of work, earnings and why you left.
3. Add medical and vocational evidence. Treatment records, physician statements describing work limitations, and a vocational expert opinion can carry real weight.
4. Add lay statements. Statements from former supervisors, coworkers or family describing missed work and limitations help show day-to-day impact.
5. Think about raising your ratings too. If you are just under the threshold, a rating increase or a secondary condition claim may get you there.

Common TDIU questions

Can I work part time and get TDIU?

Possibly. Part-time or occasional work that stays at or below the poverty threshold for one person, or work in a protected environment, can still qualify as marginal employment.

Is TDIU the same as a 100% rating?

TDIU pays at the 100% rate, but your schedular rating stays the same. Permanent and Total (P&T) status is a separate determination that can affect benefits such as Dependents’ Educational Assistance.

Can I get TDIU and Social Security disability at the same time?

Yes. They are separate programs with different rules, and a Social Security disability decision can be useful evidence for a TDIU claim.

Does age count?

No. VA cannot deny or grant TDIU based on age. The question is whether your service-connected conditions alone keep you from working.
