TDIU (Individual Unemployability)
Required Forms
What TDIU is
(, sometimes called IU) is a VA benefit that pays compensation at the 100% rate when service-connected conditions prevent the from securing or following a substantially gainful occupation, even though the is less than 100%.
is governed primarily by 38 CFR § 4.16. It exists because the rating schedule cannot capture every situation — some veterans with 70% combined ratings cannot work, while others with 90% schedular ratings can. TDIU adjusts for that reality.
Schedular vs. extraschedular TDIU
- (38 CFR § 4.16(a)) — one service-connected disability at 60% or higher, OR two or more disabilities combining to at least 70% with at least one rated 40% or higher.
- (38 CFR § 4.16(b)) — for veterans who do not meet the percentage thresholds but are nonetheless unable to work due to service-connected conditions. Requires referral to the VA Director of .
The 'substantially gainful employment' standard
generally means work that pays at or above the federal poverty threshold for one person. Earnings below that threshold are considered marginal employment and do not disqualify .
Sheltered or protected work environments — such as a family business, a job with significant accommodations, or part-time work the can only sustain in limited settings — may also be classified as marginal even if earnings exceed the poverty line.

Check your record against the § 4.16 pathways
| If your record shows this | What it means |
|---|---|
| One condition at 60%, or a combined 70% with one at 40% | Schedular TDIU is on the table under 38 CFR § 4.16(a). |
| Below those percentages but unable to hold gainful work | Extraschedular referral to the Director, Compensation Service under § 4.16(b). |
| Earnings at or below the poverty threshold for one person | Marginal employment — not substantially gainful, regardless of hours worked. |
| Work in a family business, from home, or with accommodations | Protected environment; treated as marginal on a facts-found basis. |
| The denial cites your age or a non-service-connected condition | Neither may be considered in a TDIU determination. |
| SSA already found you disabled | Relevant evidence VA must consider, though SSA and VA apply different standards. |
