TDIU: Get Paid at 100% When You Can't Work

What it is

TDIU is one of the most valuable benefits VA offers, and one of the most overlooked. Say your combined rating is 70%. On paper that pays a lot less than 100%. But if your back, your PTSD, or your knees keep you from holding a real job, VA can pay you at the full 100% rate anyway. That's what TDIU does. VA looks at your real life, not just the math on your rating.

The key phrase is "substantially gainful employment." That means a steady job that actually supports you. If you can only do small, off-and-on work, that's called "marginal employment," and it doesn't block TDIU. Work in a protected setting, like a family business that makes special allowances for you, may also count as marginal.

Who qualifies

You need a service-connected rating that meets one of two paths:

• At least one condition rated 60% or higher, or
• A combined rating of 70% or higher, with at least one condition rated 40% or higher.

Conditions from the same injury or the same body system can sometimes count as "one condition" for this test. For example, both knees, or several problems from one injury, may be grouped together.

If you don't meet those numbers, you can still ask. VA can send unusual cases (such as frequent hospital stays) to a special review. These are harder to win, but it is possible.

Your age and conditions that aren't service connected don't count. The question is only whether your service-connected conditions keep you from working, given your education and work history.

How to apply, step by step

1. Make sure you already have a disability claim or rating. TDIU sits on top of your service-connected conditions. If you're not rated yet, file that claim first or at the same time.
2. Fill out VA Form 21-8940. It asks about your disabilities, your schooling, and every job you've held in the last five years.
3. Get VA Form 21-4192 to your recent employers. Send one to each employer you worked for in the last year you worked. If an employer is gone or won't answer, tell VA what you tried.
4. Add evidence. Strong support includes a letter from your doctor saying your conditions keep you from working, records of jobs you lost or had to leave, and statements from coworkers or family. A vocational expert's report can also help.
5. Submit online, by mail, or with an accredited representative. A free VSO can help you put the package together.
6. Go to any exams VA schedules. Talk about how your conditions affect your ability to sit, stand, focus, deal with people, and show up on a regular schedule.

After you're approved

VA may send you VA Form 21-4140 to check that you still aren't working a steady job. Answer it on time. If you start working a regular job, tell VA so you don't build up a debt.

If VA rates your TDIU as permanent and total (P&T), your family may also qualify for CHAMPVA health care and education benefits like Chapter 35 DEA.

Mistakes to avoid

• Thinking you need a 100% rating first. That's the whole point of TDIU. You don't.
• Ignoring part-time work. Low-income or on-and-off work may still allow TDIU. Don't assume you're out.
• Leaving the employer forms blank. Missing forms slow everything down. Document every attempt to reach an employer.
• Not saying why you can't work. VA needs to see the link between your service-connected conditions and your lost work, not just that you're out of a job.
• Forgetting to report a new job. Overpayments can be large and hard to fix.
