VA TDIU Eligibility: How to Qualify for Individual Unemployability
Last updated: September 2026
Part of our Ratings & Compensation guides
If your service-connected conditions keep you from holding a steady job, you may be able to get paid at the 100% rate even if your combined rating is lower. That benefit is called TDIU, and many of the veterans I work with have never heard of it. I'm an Air Force veteran, and before I started Drakov Industries I worked in HR. I've seen employment records from both sides of the desk. This guide covers who qualifies, how to apply, and what evidence VA looks for.
What Is TDIU?
TDIU stands for Total Disability based on Individual Unemployability. VA pays it when your service-connected disabilities stop you from getting or keeping a "substantially gainful" job, even though your combined rating is below 100%.
Say your combined rating is 70%, but your back injury rules out every job you're trained for. TDIU was built for that situation. For 2026, TDIU pays the same as a 100% rating: $3,938.58 a month for a veteran with no dependents. Your underlying rating stays the same. Only the payment changes.
There are two paths to TDIU:
Schedular TDIU means you meet VA's rating thresholds.
Extraschedular TDIU means you don't meet the thresholds, but your conditions still keep you from working.
Both are set out in 38 CFR § 4.16. VA's own overview is on its Individual Unemployability page.
Schedular TDIU: The 60% and 70% Rules
You meet the schedular rules if you have either of these:
One service-connected disability rated 60% or higher, or
Two or more service-connected disabilities with a combined rating of 70% or higher, where at least one is rated 40% or higher.
For the first path, VA can treat several conditions as "one disability" if they:
Affect one or both arms, or one or both legs
Share a common cause
Affect a single body system
Came from multiple injuries in combat
Came from time as a prisoner of war
For example, if both knees are rated 30%, VA combines them and adds a small bilateral bump. That comes to about 56%, which rounds up to 60% and counts as one disability.
Another example is diabetes rated 40% with nerve damage (peripheral neuropathy) in all four limbs rated 10% each. That combines to about 63%, which rounds to 60%. Because the neuropathy comes from the diabetes, VA can count it all as one disability.
For the second path, remember that VA doesn't add your ratings together. It uses the combined ratings table, which usually gives a lower number than simple addition. Two combinations that reach 70% are:
PTSD at 50% and a back condition at 40%
A back condition at 40%, nerve pain in both legs at 20% each, and GERD at 10%
Extraschedular TDIU: When You Don't Meet the Numbers
Some veterans can't work but don't meet the percentages. Take migraines. The highest rating for migraines is 50%. But if you have 15 to 20 attacks a month that put you in bed, no employer can work around that many absences.
In these cases, the regional office can't grant TDIU by itself. It sends your claim to VA's Director of Compensation Service for a decision. You need to show that your conditions keep you from working, and that the rating schedule alone doesn't capture that.
Evidence that helps an extraschedular claim includes:
Medical opinions that explain why you can't work
A work history showing jobs you couldn't keep
Accommodations that were tried and didn't work
A vocational assessment finding that employment isn't feasible
One client I worked with won extraschedular TDIU with arthritis in her dominant hand rated 40% and PTSD rated 30%. That's 60% combined, below the schedular line. The hand condition ruled out physical labor. The PTSD ruled out customer-facing and high-stress office jobs. Her entire education and work history was in construction, so she had no realistic job options left.
What "Substantially Gainful Employment" Means
This is the heart of every TDIU claim. Work isn't "substantially gainful" if it's marginal. Under the regulation, work is generally marginal if your earned income for the year is at or below the Census Bureau's poverty threshold for one person. The Census Bureau updates that number every September. The most recent figure for one person under 65 is a little over $16,000 a year.
Only earned income counts. Your spouse's income, investments, military retirement, and SSDI don't count against this limit.
Work can also be marginal if it happens in a protected environment, no matter how much it pays. Examples include:
A family business that makes special allowances for you
A job created just for you that wouldn't otherwise exist
A job that allows far more absences or accommodations than a normal employer would
For example, say you "work" at your brother's company. He lets you come in when you can and stay home when your symptoms flare. No typical employer would do that, so VA may treat the job as protected rather than competitive.
VA also looks at your work history as a whole. That includes how long you kept jobs and why you left them. A string of short jobs that ended because of your service-connected conditions helps show you can't stay employed.
How to Apply
You apply with VA Form 21-8940, the Veteran's Application for Increased Compensation Based on Unemployability. It asks for:
Your employment history for the last 5 years you worked
Your education and training
The disabilities that keep you from working
When you became too disabled to work
When you last worked full-time
Your highest gross monthly earnings
Be specific on this form. The veterans I've seen denied often wrote vague answers like "my back hurts." Strong applications give real examples with dates, such as missed shifts, tasks you couldn't do, and why you left each job.
VA will also ask your past employers to fill out VA Form 21-4192, the Request for Employment Information. Here's a tip from my HR years: the person who completes that form is often a payroll or HR clerk who never met you. Call ahead, tell them it's coming, and ask who handles it. If an employer never responds, write down each attempt you made. VA has a duty to help you get those records.
Processing times change often, so check VA's current average wait times rather than relying on a number from a blog post, including this one.
Common mistakes to avoid:
Leaving off service-connected conditions that affect your ability to work
Giving an incomplete job history
Not explaining why you left each job
Working full-time in a competitive job while applying
Sending medical evidence that doesn't address your ability to work
Building Your Evidence
The strongest evidence ties your service-connected conditions directly to specific work limits.
Medical evidence includes:
Opinions from your treating providers stating that your service-connected conditions prevent you from working
Functional capacity evaluations of your physical or mental limits
Treatment records showing that your symptoms are severe and ongoing
Records of medication side effects, such as drowsiness or slowed thinking
When you ask a provider for an opinion, give them a description of your past jobs, what those jobs required physically and mentally, and how your conditions get in the way. Doctors write better opinions when they know what "work" means for you.
Consistent treatment matters. Gaps in care can make VA question how severe your conditions are. If you had gaps because of cost, transportation, or access, say so.
Work history evidence includes:
Dates of each job (month and year)
Job titles and main duties
Why you left each job
Accommodations you received or were denied
Your earnings, to show whether work was marginal
Performance reviews, attendance records, and discipline tied to your symptoms can all help. So can letters from former supervisors. As a former HR professional, I can tell you these records often exist in a personnel file, even if nobody ever showed them to you. You can ask for them.
A vocational expert can help if your work history is complicated, if VA thinks you have transferable skills, or if you need to explain why you can't switch to a different field.
Education can cut both ways. A degree may suggest you could do desk work. But if your conditions rule out the jobs your degree prepared you for, explain that clearly. As someone with an MBA, I know a degree doesn't help much if your concentration or reliability is gone.
Mental Health Conditions and TDIU
Mental health limits are harder to see than physical ones, so they need clear documentation. Suppose your PTSD is rated 70%, but you also have panic attacks in crowds, trouble finishing tasks, and anger outbursts that have cost you jobs. Your rating decision may not capture all of that.
Focus on documenting:
Social problems: trouble working with coworkers, supervisors, or customers
Concentration problems: trouble following instructions or finishing tasks
Reliability problems: how often symptoms would cause you to miss work
Trouble adapting: difficulty handling stress, change, or pressure
Planning problems: trouble organizing or finishing multi-step work
Ask your mental health provider to describe your specific workplace limits and how your medications affect your work. A symptom journal also helps. Track how often your symptoms happen, how long they last, and how bad they get, and note how each would affect a workday.
Does Age Matter?
Under current rules, no. 38 CFR § 4.19 says VA can't grant or deny TDIU based on age. The only question is whether your service-connected conditions keep you from working. VA can consider your education and work history.
One thing to watch: in June 2026, the TDIU Reform Act of 2026 (H.R. 9135) was introduced in the House. It would write TDIU into federal law and stop TDIU payments at age 67 for veterans who first get TDIU on or after December 31, 2026. Veterans already on TDIU would not be affected. This bill is not law. Most bills never get past committee. I'll update this post if that changes.
TDIU and Social Security Disability
An approval for Social Security Disability Insurance (SSDI) can support your TDIU claim, but it doesn't guarantee approval. The two programs use different rules:
SSDI looks at all your medical conditions. TDIU looks only at service-connected ones.
SSDI considers age. TDIU can't.
SSDI requires a disability expected to last at least 12 months. TDIU can be temporary.
If you have an SSDI approval, send VA your full SSDI file. Point out where it mentions your service-connected conditions, and include any functional assessments.
You can receive both TDIU and SSDI in full, with no offset between them. Keep in mind that the combined income could affect programs that are based on income.
Working While on TDIU
You can work while on TDIU, within limits:
You can't hold substantially gainful employment.
You can do marginal work, meaning earnings at or below the poverty threshold.
You can work in a protected environment, if you can show the job gives you accommodations a normal employer wouldn't.
VA used to require a yearly employment questionnaire. It stopped that annual requirement and now matches wage data with the Social Security Administration. If the match shows earnings above the threshold, VA will send you VA Form 21-4140 or a notice proposing to end your TDIU. Respond by the deadline. This is your chance to show the work was marginal, protected, or wrongly reported. If you ignore it, VA can reduce your pay to your combined rating and create a debt.
There's also a safety net. Under 38 CFR § 3.343(c), VA generally can't end TDIU just because you took a gainful job unless you keep that job for 12 months in a row.
If you're going back to work for good, tell VA. Stopping TDIU yourself is much easier than paying back an overpayment.
Temporary vs. Permanent and Total TDIU
Some TDIU awards are temporary. Others are marked Permanent and Total (P&T). Signs your TDIU is P&T:
Your award letter says "Permanent and Total"
Your decision says no future exams are scheduled
You get information about Chapter 35 education benefits for dependents
P&T status can open up:
CHAMPVA health coverage for eligible family members
State benefits for P&T veterans, which vary by state
Fewer routine re-exams
If your TDIU isn't P&T, VA may schedule re-exams and check your work status from time to time.
Conclusion
TDIU exists for veterans whose service-connected conditions have taken away their ability to work, even when their ratings don't reach 100%. Get your medical and work evidence together, fill out Form 21-8940 with real detail, and make sure your past employers know Form 21-4192 is coming. If VA denies your claim, you have one year to choose a decision review option. Many veterans win on a second try with better evidence.
