TDIU 2026: get 100% pay without a 100% rating

Updated June 2026 · Source: 38 CFR §4.16

TDIU — Total Disability based on Individual Unemployability — pays at the 100% disability compensation rate even when your schedular rating is lower than 100%. For 2026, that means $3,938.58/month before dependents — the same as a 100% schedular rating. VA estimates that several hundred thousand veterans may qualify for TDIU but have never filed. The bottleneck is awareness, not eligibility.

What TDIU is worth in 2026

The gap between your current rating and 100% TDIU pay in 2026:

Current schedular ratingCurrent monthly payTDIU monthly payMonthly gain from TDIU
60%$1,435.02$3,938.58+$2,503.56
70%$1,808.45$3,938.58+$2,130.13
80%$2,102.15$3,938.58+$1,836.52
90%$2,362.30$3,938.58+$1,575.59

The §4.16(a) schedular threshold

To qualify for TDIU under the standard schedular path, you must meet one of these rating criteria AND the employment criterion below:

Path A:

ONE service-connected disability rated at 60% or higher.

Path B:

Combined rating of 70% or higher, with at least one disability at 40% or higher.

AND in both cases: you must be unable to maintain substantially gainful employment because of your service-connected disabilities. Non-service-connected health conditions or economic factors do not count.

What "substantially gainful employment" means

VA uses the federal poverty threshold for a single individual as the practical dividing line. For 2026, this is approximately $15,650/year. If your earnings from employment consistently exceed this threshold, VA may consider you capable of substantially gainful employment.

Important nuances:

§4.16(b) extra-schedular path

Veterans who do not meet the §4.16(a) rating thresholds may still qualify under §4.16(b) if their service-connected disabilities prevent substantially gainful employment. This path requires:

  1. A finding that the veteran is unemployable due to service-connected conditions even though the rating thresholds are not met.
  2. Referral to and approval by the Director, Compensation Service (or designee).
  3. Evidence demonstrating unique vocational limitations — typically a vocational expert opinion, extensive work history showing inability to maintain employment, or medical evidence of functional limitations not fully captured by the rating schedule.

§4.16(b) TDIU is harder to obtain than §4.16(a) TDIU. However, for veterans with a 60% combined rating spread across many small disabilities (none reaching 40%), it may be the only path.

Evidence that supports a TDIU claim

Strong TDIU claims include multiple types of evidence addressing both the rating threshold and the employment impact:

How to file — VA Form 21-8940

File VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Unemployability). Key sections to complete carefully:

A free VSO will help ensure the form is filled correctly and all supporting evidence is attached. Do not leave any section blank — gaps invite requests for more information and delay processing.

FAQ

What counts as "substantially gainful employment" in 2026?

VA generally uses the federal poverty threshold for a single person as the dividing line — approximately $15,650/year for 2026. Earnings consistently above that level for 12 months may result in TDIU termination. Marginal employment (below the threshold) or work in a protected or sheltered environment is not considered substantially gainful.

Is TDIU permanent?

TDIU can be granted as Permanent and Total (P&T), in which case future re-exams are not required. P&T is typically granted when the disabling conditions are considered static or unlikely to improve. Without P&T status, VA may schedule routine future examinations.

Do I lose TDIU if I work?

You can lose TDIU if your earnings exceed the marginal-employment threshold for 12 consecutive months. VA Form 21-4140 (Employment Questionnaire) may be required to report work activity. Talk to a VSO before taking on substantial work while receiving TDIU.

Does TDIU pay more than 90%?

Yes. TDIU pays at the 100% compensation rate regardless of your schedular rating. For 2026, that is $3,938.58/month for a single veteran with no dependents. If your schedular rating is 90% ($2,362.30/mo), TDIU adds $1,575.59/month.

Can I get TDIU if I have a 70% combined rating but no single disability at 40%?

The §4.16(a) schedular threshold requires 70% combined with at least one disability at 40% or more. If your 70% is spread across many small ratings with no single disability at 40%, you may still qualify under §4.16(b) extra-schedular if VA determines your specific occupational limitations are severe enough — but this path is harder and requires referral to the VA Director of Compensation Service.

Does TDIU affect Social Security Disability (SSDI)?

TDIU and SSDI are separate programs with separate eligibility rules. Receiving TDIU does not automatically grant SSDI, and SSDI does not automatically grant TDIU. However, a favorable SSDI decision can serve as strong supporting evidence for a TDIU claim, and vice versa. VA disability compensation does not count as income for SSDI purposes.

What is the difference between schedular 100% and TDIU?

A schedular 100% rating means VA rated your combined disabilities at 100% using the combined ratings formula. TDIU pays at the 100% rate without reaching 100% schedular. For most compensation purposes the dollar amount is identical. Key difference: P&T status, dependency and indemnity compensation (DIC) eligibility for survivors, and Chapter 35 DEA educational benefits may attach to P&T TDIU.
