VA Individual Unemployability Checklist: Rating Thresholds, Forms and 100% Compensation

A Individual Unemployability, often called TDIU, can pay a veteran disability compensation at the same rate as a 100% disability rating even when their assigned combined rating is lower. It applies when service-connected conditions prevent steady, financially supporting work.

Approval does not change a veteran’s official disability rating to 100%. It changes the monthly payment amount to the 100% rate while the underlying rating remains the same. 

Eligibility Checklist

Use this checklist before applying. A veteran must meet the work requirement and at least one of the rating requirements.

These thresholds come directly from the VA’s Individual Unemployability eligibility page.

What “Substantially Gainful Employment” Means

Substantially gainful employment means a job that provides enough income to support the veteran financially. The VA looks at whether the veteran can hold that kind of steady job because of service-connected conditions.

Marginal employment does not count. The VA’s example describes a veteran with a 60% service-connected heart condition who could no longer perform physical work without chest pain; the VA approved Individual Unemployability after reviewing medical evidence, work history and education. 

A veteran does not have to be completely unemployed to apply. However, the VA must determine that any current work is marginal rather than substantially gainful. 

VA Form 21-8940 Requirements

VA Form 21-8940 is the official application for increased compensation based on unemployability. It can be completed online or downloaded and submitted by mail. 

The VA says it will review both work and education history when deciding an Individual Unemployability claim. 

100% Compensation Rules

If approved, the VA pays compensation at the 100% rate, but it does not automatically assign a 100% disability rating. The veteran’s rating stays the same while the monthly payment rises to the 100% level. 

For 2026, the VA’s current compensation-rate table lists the following 100% rates, effective December 1, 2025.

Additional amounts may apply for more children, a spouse receiving Aid and Attendance or dependent parents. The VA’s rate tables explain how to calculate those additions.

What to Submit With Your Claim

The VA’s additional-forms guidance says veterans claiming Individual Unemployability should submit both required forms with their disability claim. 

Before submitting, make sure you have:

1. A filed service-connected disability claim.

2. Completed VA Form 21-8940.

3. Completed VA Form 21-4192 from your most recent employer.

4. Medical evidence connecting your inability to work to service-connected conditions.

5. A clear work and education history.

6. Any evidence showing marginal employment, if you are working occasionally.

If the VA later asks you to verify employment status, use VA Form 21-4140, the Employee Questionnaire.

Where to Apply

Veterans can apply online or by mail through the VA’s Individual Unemployability page. The VA also provides the application page for Form 21-8940.

For questions, contact the VA through its official website or call the VA benefits helpline. Use only official VA.gov channels when submitting personal, medical or employment information.
