TDIU (also called IU — Individual Unemployability) allows veterans who cannot maintain substantially gainful employment due to service-connected conditions to receive VA disability compensation at the 100% rate ($3,938.58/month in 2026), even if their combined rating is lower. TDIU is one of the most misunderstood and underused benefits available.

Can I work and still qualify for TDIU in California?
You may qualify if your income falls below the federal poverty threshold for substantial gainful activity — approximately $15,960/year per 38 CFR §4.16(a) (Census Bureau poverty line, 2026). Part-time, irregular, or sheltered work (e.g., in a protected environment) generally does not disqualify you. Veterans in California should discuss their specific work history with a VSO or VA-accredited claims agent before filing.
Does TDIU pay the same as a 100% disability rating in California?
TDIU pays at the 100% disability compensation rate ($3,938.58/month for a veteran alone in 2026), which is the same monthly dollar amount. The key difference: a schedular 100% rating can stack state-specific benefits (like California's full property tax exemption), while TDIU may or may not unlock state programs depending on how California defines eligibility. Check with California Department of Veterans Affairs (CalVet).
What is 'substantially gainful employment' for TDIU purposes in California?
Substantially gainful employment means work that pays above the federal poverty threshold and is consistent, full-time-like in nature. It does not include sheltered workshops, work in a protected environment, or income below approximately $15,960 annually (38 CFR §4.16(a)). The standard is federal, so it applies uniformly to veterans in California and every other state.
