TDIU — Total Disability based on Individual Unemployability — is one of the most powerful benefits in the VA system and one of the most underutilized. If your service-connected disabilities prevent you from maintaining substantially gainful employment, TDIU pays you at the 100% rate ($3,831.30/month in 2026) even if your combined rating is only 60%, 70%, or 80%. This is not a loophole. It is what the benefit is designed for.
The basic eligibility rules
To qualify for TDIU, you generally need either: (a) a single service-connected disability rated at 60% or higher, or (b) two or more service-connected disabilities with a combined rating of 70% or higher, where at least one individual disability is rated at 40% or higher. These are the “schedular” requirements. There is also “extraschedular” TDIU for veterans who don’t meet these thresholds but can demonstrate through medical and work history evidence that their service-connected disabilities are the reason they cannot work. Extraschedular TDIU is harder to get but absolutely exists.
What “substantially gainful employment” means
You don’t have to be bedridden to qualify. “Substantially gainful employment” means employment that provides income above the federal poverty threshold. Part-time work, marginal employment, or sheltered employment (work in protected settings that accommodate your disabilities) does not count against you. Many veterans who work limited hours or in accommodated roles still qualify for TDIU. The key question is whether your service-connected conditions are the reason you cannot sustain full-time competitive employment.
How to apply: VA Form 21-8940
TDIU claims are filed using VA Form 21-8940, the Veterans Application for Increased Compensation Based on Unemployability. The form asks about your work history, education, and the specific ways your disabilities prevent you from working. Get supporting documentation from your treating physicians explaining how your conditions affect your ability to work. Work history evidence — employer statements, Social Security records, tax returns showing employment gaps — strengthens the claim. A VA-accredited claims agent or VSO can help you build the package.
TDIU income limits in 2026
You can earn some income while receiving TDIU — the limit is roughly the federal poverty level for one person, which in 2026 is approximately $15,060/year. Earned income above this threshold can trigger a TDIU termination. Investment income, retirement benefits, and Social Security disability do not count toward the limit. If you’re working part-time and receiving TDIU, know your income ceiling and stay informed about any changes to VA policy on earned income.
