VA Form 21-8940: TDIU Application & Benefits Guide 2026 – VA Form 21-8940 is the official application used by U.S. veterans to seek Total Disability based on Individual Unemployability (TDIU) benefits. This allows eligible veterans to receive compensation at the 100% disability rate even if their combined VA disability rating is less than 100%, provided service-connected conditions prevent substantially gainful employment.

What Is VA Form 21-8940 and TDIU?
VA Form 21-8940, titled “Veteran’s Application for Increased Compensation Based on Unemployability,” is the key document for claiming TDIU (also called Individual Unemployability or IU). When approved, it provides monthly compensation equivalent to a 100% disability rating.
TDIU recognizes that some veterans cannot maintain steady, substantially gainful work due to service-connected disabilities, even with lower schedular ratings. “Substantially gainful employment” generally means earning above the federal poverty threshold (marginal or sheltered employment may still qualify).
The current revision (as of 2024/2025) can be completed online via the VA website or on paper.
Who Is Eligible for TDIU Benefits via VA Form 21-8940?
To qualify for TDIU, you must meet these criteria (per official VA guidelines):
- Your service-connected disability(ies) prevent you from securing or following substantially gainful employment.
- AND one of the following rating thresholds:
- One service-connected disability rated at 60% or higher, OR
- Two or more service-connected disabilities with a combined rating of 70% or higher, with at least one rated at 40% or higher.
In exceptional cases (e.g., frequent hospitalizations), veterans may qualify with lower ratings. Your overall disability rating does not change; only the compensation level does.
