Two Ways to Qualify
Route 1 — Single Disability at 60%+
One service-connected disability is rated 60% or higher. This is the most straightforward TDIU path — you need one condition severe enough to drive unemployability.
Route 2 — Combined Rating 70%+, with One at 40%+
Your combined VA rating is 70% or higher, AND at least one individual disability is rated 40% or higher. Common scenario: 50% PTSD + 30% back = 65% combined, but if PTSD is 40%+ it may still qualify if the combined rounds to 70%+.
Extraschedular TDIU
Veterans who don't meet the standard rating thresholds can still qualify if their specific disability combination clearly prevents any substantially gainful employment. Requires a referral to the Director of Compensation Service. Under 38 CFR §4.16(b).

What Is "Marginal Employment"?
Under 38 CFR §4.16(a), you can do limited work without losing TDIU — as long as it qualifies as "marginal employment." Marginal employment means annual earned income does not exceed the poverty threshold for a single person as established by the U.S. Census Bureau (approximately $15,960/year as of the most recent Census poverty guidelines — distinct from the HHS poverty level used for other programs).
A "protected work environment" — where an employer substantially accommodates your disability (family business, sheltered workshop) — doesn't count as substantially gainful employment regardless of income.
How to File for TDIU
Step 1 — File VA Form 21-8940
This is the dedicated TDIU application. It documents your work history and how your service-connected conditions prevent employment. File it even if you stopped working years ago — the date you file locks in your potential effective date.
Download VA Form 21-8940 →Step 2 — Get a Nexus Letter from Your Doctor
Your treating physician should write a letter explaining, by name of each service-connected condition, how those disabilities prevent you from holding a full-time job. Be specific — this letter is critical.
Step 3 — Submit Employment Records
Termination paperwork, FMLA records, reduced hours documentation — anything that shows your disability forced you out of or significantly reduced your employment. Employer statements work too.
Step 4 — File VA Form 21-4142 (Records Authorization)
Authorizes the VA to pull records directly from your private medical providers, strengthening your claim without extra legwork.

Can I work at all if I have TDIU?
Yes — you can do limited work that qualifies as "marginal employment" (under ~$15,960/year per Census poverty threshold, or work in a protected environment). Report any employment changes to the VA. Working above this level risks termination of TDIU.
Does TDIU affect my Social Security Disability (SSDI)?
No. VA disability compensation, including TDIU pay, is not counted as earned income and does not reduce SSDI benefits. Many veterans receive both TDIU and SSDI simultaneously. In fact, an SSDI award can help prove unemployability for your TDIU claim.
Can TDIU become permanent?
Yes — the VA can designate TDIU as Permanent and Total (P&T) if your conditions are unlikely to improve. P&T TDIU unlocks all 100% P&T benefits, including CHAMPVA for dependents and full property tax exemptions in states that require P&T status.
What's the difference between TDIU and a 100% schedular rating?
A 100% schedular rating means your combined disability rating math reaches 100%. TDIU pays at the 100% rate even when the math doesn't get there — it's based on unemployability, not rating arithmetic. Benefits are identical in dollar amount; some state property tax rules distinguish between them.
Will the VA re-examine me if I have TDIU?
The VA schedules future exams unless TDIU is permanent. Veterans over 55, or with conditions rated permanent, are rarely re-examined. Always notify the VA immediately of any change in employment status.
