TDIU turns on whether you can hold substantially gainful employment — not whether you do literally zero work. Under 38 CFR 4.16(a), marginal employment (generally earnings at or below the federal poverty threshold for one person, or sheltered/protected work) doesn't by itself disqualify you. The line between marginal and substantially gainful is where TDIU is kept or lost.
Straight talk first
This is the question that scares people off TDIU: "If I mow a lawn or work a few hours, do I lose everything?" The honest answer is no, not automatically — TDIU was never meant to require you to sit at home and earn nothing. It's about whether you can sustain a real, gainful job. There's a defined line, and you're allowed to do some work below it. What you can't do is hold down substantially gainful competitive employment and collect TDIU at the same time. Know the line, stay honest, and you're fine.
This is the employment cut of the TDIU pillar.
Substantially gainful vs. marginal
- Substantially gainful employment — competitive work producing earnings above the poverty threshold. Sustaining this generally signals you can work, which is inconsistent with TDIU.
- Marginal employment — generally earnings at or below the federal poverty threshold for one person. This does not disqualify you.
Sheltered and protected work
Marginal employment isn't only about the dollar amount. 4.16(a) also recognizes work in a protected environment — such as a family business or a sheltered workshop — as potentially marginal even when earnings exceed the poverty threshold, on a facts-found basis. The idea: if you only keep the job because of special accommodations no ordinary employer would make, it isn't truly "gainful" employment.
Where veterans get into trouble
- Assuming any work kills TDIU — and never applying, or quitting work they could keep within the marginal line.
- Drifting over the line — taking on competitive work that climbs above the threshold without realizing it can put TDIU at risk.
- Not being straight about income — VA can review your employment status; honesty protects you, and misreporting creates real problems.
Play it smart
- Know the current poverty threshold for one person (it updates yearly — check the Census figure).
- Track your earned income against it.
- If you're considering work, understand whether it would stay marginal (below the threshold, or genuinely sheltered) before you commit.
- Keep documentation of any accommodations if you're relying on the protected-work concept.
Then make sure the rest of your claim is solid — the eligibility thresholds and the application. Pointman is education-only and not VA-accredited; an accredited representative can advise on your specific income situation.
Key takeaways
- TDIU = can't hold substantially gainful work — not "earn zero."
- Marginal employment (≤ the poverty threshold for one person) generally doesn't disqualify you.
- Sheltered/protected work can be marginal even above the threshold, case by case.
- Be honest about income — VA can review status, and competitive earnings above the line risk TDIU.
Frequently asked questions
- Can I work at all and still get TDIU?
- Yes, within limits. TDIU turns on whether you can hold substantially gainful employment, not whether you do literally no work. Marginal employment — generally earnings at or below the federal poverty threshold for one person, or work in a protected/sheltered setting — doesn't by itself disqualify you.
- What is 'marginal employment'?
- Under 38 CFR 4.16(a), marginal employment generally exists when your earned annual income doesn't exceed the federal poverty threshold for one person. It can also include certain sheltered or protected work, like a family business or an accommodating employer, even above that income level.
- What counts as 'substantially gainful' employment?
- Generally, work that produces earnings above the poverty threshold and isn't a protected/sheltered arrangement. Steady competitive employment at that level usually signals you can sustain gainful work, which is inconsistent with TDIU.
- Will taking a small job cause me to lose TDIU?
- Not necessarily, if it stays within marginal employment. But VA can review your status, so be honest about your income and work, and understand where the line is before you take on work — earnings above the threshold in competitive employment can put TDIU at risk.
