Can You Work Part-Time on TDIU Without Losing Benefits?

CCK Law: Our Vital Role in Veterans Law

Yes, in many cases, veterans receiving Total Disability based on Individual Unemployability (TDIU) can work part-time without losing their benefits. The key is whether the Department of Veterans Affairs (VA) considers that employment “marginal” rather than “substantially gainful.”

In this article, you will learn more about these terms, the general circumstances where veterans can work part-time while receiving TDIU, and how to proactively protect a TDIU claim from VA review.

Key points of this article include:

• Marginal employment is typically defined as when a veteran earns below the federal poverty threshold. It generally does not disqualify a veteran from TDIU.
• Protected work environments can also count as marginal and typically involve special accommodations a veteran is given to accommodate their disabilities.
• VA may monitor employment status through various methods, so veterans should report part-time work honestly and keep documentation of any accommodations they receive.

When Can I Work Part-Time on TDIU?

Veterans can generally work part-time while receiving VA TDIU benefits as long as VA considers their employment “marginal.”

Under 38 CFR § 4.16, marginal employment is work that does not rise to the level of “substantially gainful employment,” which is the standard that would ordinarily disqualify a veteran from TDIU.

There are two ways employment can be considered marginal:

When Earning Below the Federal Poverty Threshold

“Earning below the annual federal poverty threshold for a single individual is not considered substantially gainful employment,” says Emma Peterson, partner at CCK Law. “In that case, employment shouldn’t affect your TDIU benefits.”

For 2024, the federal poverty threshold for a single individual was about $16,320 per year. Veterans who earn less than this income limit can continue to receive TDIU benefits, whether they work part-time or full-time.

This threshold is updated annually by the U.S. Census Bureau.

When Working in a Protected Work Environment

Under 38 CFR § 4.16, marginal employment may also exist when a veteran works in a protected work environment — even if their income exceeds the poverty threshold.

“The regulations suggest that a protected workplace is one where a veteran receives special accommodations,” says Emma Peterson. “They’re maybe held to a less rigorous schedule or productivity standard, or are otherwise shielded from the competitive demands of the open labor market.”

Examples of a protected work environment might include:

• Working for a friend or family member who allows the veteran to set their own schedule or leave whenever their condition requires.
• A sheltered workshop or other employer that accommodates a veteran’s disability by letting them be less productive or less reliable than other workers (e.g. being allowed to arrive late due to restless sleep from sleep apnea).
• Other jobs where the veteran’s continued employment depends on accommodations that would generally not be considered in a standard workplace.

Veterans should be aware that VA has not established a firm definition of “protected work environment,” making these cases fact-intensive. The Court of Appeals for Veterans Claims has identified factors, however, such as the degree of accommodation required, the veteran’s job responsibilities, and whether the work is full- or part-time as relevant considerations.

• In Cantrell v. Shulkin, 28 Vet. App. 382, 390–91 (2017), the Court acknowledged this regulatory gap and held that VA’s failure to define “protected environment” frustrated judicial review.
• In 2024, the Veterans Court also decided LaBruzza/McBride v. McDonough, 37 Vet.App. 111, further specifying that “employment in a protected environment” under 38 C.F.R. § 4.16(a) means a lower-income position that, due to a veteran’s service-connected disability or disabilities, is shielded in some respect from competition in the employment market.

However, again, these cases remain highly fact-specific and often hinge on employer statements, accommodation evidence, and vocational analysis. An attorney experienced specifically in TDIU cases may be able to assist.

How Can I Prove My Part-Time Work Is Marginal?

If a veteran is working part-time while receiving TDIU, VA may review their employment to confirm it does not amount to substantially gainful work.

To help avoid this, veterans should consider taking some of the following steps to demonstrate ahead of time that their employment is marginal:

• Reporting employment honestly and annually—VA may review a veteran’s employment status or cross-reference earnings with Social Security Administration records. Therefore, veterans should fill out VA Form 21-4140 as required and disclose any work they perform.
• Documenting all workplace accommodations—Veterans should keep records of any special arrangements their employer has made (e.g. flexible hours, permission to leave at any time, reduced workloads, etc.) that they would not typically receive in a competitive workplace.
• Asking employers to contact VA if needed—If VA questions a veteran’s employment status, their employer may be able to confirm (e.g. by submitting Form 21-4192) the accommodations the veteran receives and explain why their role could not exist in a standard work environment.
• Staying below the federal poverty threshold when possible—Earning below the annual threshold is the most straightforward way to qualify as marginally employed.

Veterans should also keep in mind, however, that these strategies are not foolproof, and even income that appears low can prompt a VA review. This is why it is always better to proactively report your work and document your limitations than to wait for VA to reach out.

Frequently Asked Questions

What is TDIU?

Total Disability based on Individual Unemployability (TDIU) is a VA benefit that allows veterans to be compensated at the 100 percent disability rate even if their combined service-connected rating is below 100 percent.

To qualify, a veteran’s service-connected disabilities must prevent them from maintaining substantially gainful employment.

What is considered “substantially gainful employment” for TDIU?

VA considers employment “substantially gainful” when a veteran earns above the federal poverty threshold (currently $16,320 per year as of September 2025) and the work does not occur in a protected environment.

Veterans capable of substantially gainful employment are generally not eligible for TDIU.

Can I work full-time and still have TDIU?

In certain circumstances, yes, as long as the employment is marginal (e.g., a full-time job in a protected environment with significant accommodations, or one that pays below the poverty threshold).

However, full-time employment may be more likely to be viewed by VA as substantially gainful. Veterans working full-time while on TDIU should be ready to defend their TDIU claim in the event that VA reviews their case.

What is VA Form 21-4140?

VA Form 21-4140 is the Employment Questionnaire that VA uses to gather information about a TDIU recipient’s work activity. Veterans receiving TDIU used to be required to complete this form annually, but at the current time, they are only required to complete the form if VA requests it.

What happens if VA receives evidence that I am working?

VA monitors TDIU recipients’ employment through annual checks with the Social Security Administration. If VA determines that a veteran’s work exceeds the marginal employment standard, it may initiate a review of their TDIU benefits, generally by sending a VA Form 21-4140 (Employment Questionnaire) request. This is when veterans have an opportunity to argue exceptions like a protected work environment. If VA does not receive a sufficient explanation, it may propose a reduction in benefits.

For this reason, veterans need to have transparent, accurate reporting and thorough documentation when working while on TDIU.
