VA Form 21-8940, known officially as the “Veteran’s Application for Increased Compensation Based on Unemployability,” is the critical document used to apply for Total Disability Individual Unemployability (TDIU). This form allows veterans to formally request to be paid at the 100% disability rate, even if their combined scheduler rating is less than 100%, because their service-connected disabilities prevent them from securing substantially gainful employment. It bridges the gap between a veteran’s medical rating and their actual economic reality, providing a pathway to maximum compensation for those unable to work.
When to Use This Form
- Applying for Initial TDIU: When a veteran believes their service-connected disabilities render them unable to work, regardless of whether they meet the standard percentage requirements (60% for a single disability or 70% combined).
- Responding to a VA Invitation: When the VA reviews a file and sees evidence that a disability interferes with employment, they may send this form and “invite” the veteran to file for unemployability.
- Documenting Employment History: To provide a detailed five-year employment history (and education history) required to substantiate how specific disabilities caused job loss or reduced earning capacity.
- Protected Work Environments: When a veteran is technically employed but works in a specialized or “protected” environment where accommodations are made that would not exist in a competitive job market.
