Unemployed vs. Unemployable: What the VA Actually Requires to Prove TDIU

The distinction that decides the claim

Two words sound almost identical and mean completely different things to the VA:

• Unemployed = you do not have a job.

• Unemployable = you are not capable of holding a job.

TDIU pays for the second, not the first. This is the exact principle the Court set in Van Hoose v. Brown, 4 Vet. App. 361, 363 (1993): the sole fact that a veteran is unemployed or has difficulty obtaining employment is not enough. A high disability rating, the Court explained, is already a recognition that your impairment makes it hard to obtain and keep work. To win TDIU, the record has to reflect some factor that takes your case outside the norm of other veterans rated at the same level — and that factor is your inability to perform the acts of employment.

What "capable of performing the physical and mental acts required by employment" means

This is the heart of the standard, so let’s make it concrete. The VA is asking whether you can reliably do the physical and mental tasks that competitive work demands — day after day, not on your best day. That breaks down into two buckets:

Physical acts of employment

Sitting, standing, and walking for sustained periods; lifting and carrying; using your hands for fine and gross tasks; stamina across a full shift; and simply showing up reliably without excessive absences.

Mental acts of employment

Sustained concentration and memory; keeping pace and persisting through a workday; interacting appropriately with supervisors, coworkers, and the public; handling ordinary workplace stress; and adapting to changes — again, on a consistent, sustained basis.

The standard is about sustained capability, not a single snapshot. Many veterans can do almost any task for ten minutes. The question is whether they can do it for forty hours a week, every week, in a competitive setting where unscheduled breaks, frequent absences, or unpredictable flare-ups would get them fired.

"Substantially gainful" employment — and the twist that surprises people

TDIU is about the inability to secure or follow substantially gainful employment under 38 CFR § 4.16. The Court defined that in Moore v. Derwinski, 1 Vet. App. 356, 358 (1991) as work ordinarily followed by the nondisabled to earn a livelihood — in other words, a living wage. Two consequences follow:

• Marginal employment does not count against you. Earnings at or below the federal poverty threshold for one person are not "substantially gainful" (38 CFR § 4.16(a)).

• You can sometimes qualify even while working. Here is the twist: if you only keep a job because of a protected environment — a family business or an employer making accommodations far beyond the norm — that employment may not defeat your claim. The question is still whether you are capable of performing the required acts, not whether some sheltered job technically exists.

Why this is exactly where claims fail

Most denied TDIU claims fail for the same quiet reason: the record proves the veteran is not working — which Van Hoose says is not enough — but never proves the veteran cannot perform the acts of work. Treatment notes describe symptoms and diagnoses. A C&P examiner checks a box that says you "can perform sedentary work" without grappling with whether you could actually obtain and sustain such a job. Nothing in the file connects your conditions to a functional inability to do the physical and mental tasks employment requires. That missing connection is the difference between a denial and a grant.

What your medical evidence has to show to satisfy Van Hoose

To meet this standard, the evidence cannot stop at "the veteran is disabled." It has to translate your service-connected conditions into specific, sustained functional limitations — which physical and mental acts of employment you cannot reliably perform, and why. This matters because functional impairment is measurable and distinct from diagnosis or symptom severity: validated instruments such as the Inventory of Psychosocial Functioning were developed precisely to capture impairment in work and role functioning separately from a symptom count.1 A strong functional evaluation does the same thing for your claim — it documents capability, not just condition.

In practice, that means a clinician-led evaluation that addresses pace, attendance, stamina, the effect of flare-ups, and the cognitive and physical demands you cannot meet on a sustained competitive basis — the precise building blocks the VA needs to find you unemployable rather than merely unemployed.

If you were denied because "you can work"

If your denial said your evidence did not show you are unable to work, or that an examiner found you "capable of sedentary work," that is the Van Hoose gap in action — the file showed you were not working, but never proved you cannot perform the acts of work. That gap is fixable with the right functional evidence.
