When veterans search for TDIU income limits, they are usually trying to answer one question: How much can I earn and still qualify for—or keep—TDIU benefits? The answer depends on whether the VA considers your work substantially gainful, marginal, or performed in a protected environment.
TDIU pays compensation at the 100% rate when service-connected disabilities prevent substantially gainful employment. Income is one of the clearest signals the VA uses to evaluate whether you are truly unemployable in the competitive labor market. Understanding the thresholds helps you file accurately and avoid surprises during annual employment verification.
For the full eligibility picture, start with our pillar guide on what TDIU is and who qualifies.
What Are TDIU Income Limits?
The VA does not publish a separate TDIU earnings chart. Instead, it applies the concept of substantially gainful employment under 38 CFR § 4.16. Work is substantially gainful when it provides earnings above the federal poverty threshold for one person, as updated annually by the U.S. Department of Health and Human Services (HHS).
For planning purposes, the 2025 poverty guideline for a single person is approximately $15,060 per year. That figure typically rises slightly each year. Veterans near the threshold should verify the current HHS amount when completing VA Form 21-8940 or responding to employment questionnaires.
Substantially Gainful vs. Marginal Employment
Substantially gainful employment is ordinary competitive work that pays above the poverty threshold. If you are performing substantially gainful work, the VA will generally find that you are not entitled to TDIU—even if your disabilities cause significant hardship.
Marginal employment is the opposite end of the spectrum. Under VA regulations, employment is marginal when annual earnings are below the federal poverty threshold for one person. A veteran working limited hours at low wages may still meet TDIU criteria if total earnings remain under the poverty line and disabilities still prevent substantially gainful work in the open market.
Our dedicated guide on TDIU marginal employment covers family business and sheltered work in more detail.
Protected Work Environments and Income
Income limits work differently when employment occurs in a protected environment. A protected job provides accommodations you would not receive in ordinary competitive employment—unlimited absences, reduced productivity standards, or a role created because of your relationship to the employer.
Work in a protected environment is not substantially gainful even when earnings exceed the poverty threshold. The VA focuses on whether the job reflects real labor-market competitiveness. Employer statements describing accommodations are critical evidence. See whether you can work while receiving TDIU for part-time and protected-work examples.
Examples: How the VA May View Your Earnings
Example 1: A veteran earns $9,200 per year at a part-time retail job. Disabilities limit standing and customer interaction. Earnings are below the poverty threshold, which may support a marginal employment finding—if medical evidence shows the veteran still cannot maintain substantially gainful work.
Example 2: A veteran earns $28,000 per year working for a spouse's company with flexible hours and no performance standards. Even though income exceeds the poverty line, the VA may treat this as a protected environment if documented accommodations show the job is sheltered.
Example 3: A veteran earns $22,000 annually in a standard full-time office role with no special accommodations. This generally indicates substantially gainful employment and would likely disqualify TDIU unless the veteran can show the work period was temporary or not actually sustained.
Reporting Income and VA Reviews
After TDIU is granted, the VA may send employment verification forms. Report income honestly and consistently. If your work situation changes—new job, increased hours, or loss of accommodations—notify the VA and your representative promptly.
If the VA proposes to reduce TDIU based on employment, you may submit evidence showing the work is marginal or protected, or that disabilities prevent continuing the job. Vocational expert analysis can help rebut a finding that competitive sedentary work is available. Learn how in our article on vocational expert evidence for TDIU.
How Vocational Evidence Fits In
Income alone does not decide every TDIU case. Some veterans earn below the poverty line yet still struggle because the VA disputes whether disabilities cause unemployability. Others earn above the threshold in sheltered jobs that do not reflect competitive employability. A vocational evaluation documents the real-world picture—transferable skills, functional limits, and labor-market access—alongside your earnings history.

Frequently Asked Questions
What is the income limit for TDIU?
The VA uses the federal poverty threshold for one person as the dividing line. Earnings above that level are generally substantially gainful; earnings below may be marginal.
Does part-time work disqualify TDIU?
Not automatically. Part-time earnings below the poverty threshold may qualify as marginal employment if disabilities still prevent substantially gainful work.
Can I earn more than the poverty line on TDIU?
Possibly, if work occurs in a documented protected environment with special accommodations not available in competitive employment.
How does the VA verify TDIU income?
Through Form 21-8940, employment questionnaires, Social Security records, and information you report. Keep records of hours, pay, and accommodations.
