Once you are receiving TDIU, the VA wants to confirm from time to time that you still qualify. One tool it uses is VA Form 21-4140, the employment questionnaire. It asks whether you have worked and what you earned during the review period. How you answer matters. A careless or inaccurate response can trigger a reduction, while an accurate one that correctly frames marginal or sheltered work protects your benefit. This guide explains the form and how to handle it.

Note that the VA has updated how and when it verifies employment over the years, and the exact questionnaire you receive may vary. The principles here apply to any TDIU employment verification.

01
What Form 21-4140 is

Form 21-4140 is an employment questionnaire the VA uses to verify that a veteran receiving TDIU remains eligible. It asks whether you were employed during the review period and, if so, details about that work and your earnings. It is essentially a periodic check that your employment status still supports the 100 percent rate.

02
When you receive it

The VA may send an employment verification like this periodically after TDIU is granted. Whether and how often you receive one has changed over time and can depend on your circumstances. Treat any employment questionnaire from the VA seriously, respond by the deadline, and keep a copy of what you submit.

03
What the questionnaire asks

  • Whether you were employed during the review period
  • Your employer, job, and hours if you worked
  • Your earnings during the period
  • The nature of the work, including any accommodations

04
Why accuracy matters

The questionnaire feeds directly into whether your TDIU continues. Reporting work you did not do would be false, and failing to report work you did can lead to an overpayment and a proposed reduction later. Accuracy protects you. If you worked within the marginal or sheltered rules, say so plainly and let the numbers show you still qualify.

05
Framing marginal and sheltered work

If you worked, the key is context. If your earnings fell below the federal poverty threshold for one person, note that the work was marginal. If the job involved significant accommodations, describe them so the VA sees it as sheltered. Presenting low earnings or accommodated work clearly keeps your benefit intact.

06
If you worked during the period

Working does not automatically end TDIU. Report it honestly and explain the category. Marginal earnings and sheltered employment are permitted. A short work attempt that failed because of your conditions should be described as a failed attempt, not as evidence that you can hold a job.

07
What happens if you do not return it

Ignoring an employment verification can itself lead to action on your benefit, since the VA needs the information to confirm continued eligibility. Always respond within the deadline. If you need more time or help understanding the form, ask, but do not simply let it go unanswered.

08
Keep your own records

Maintain your own record of any work, hours, earnings, and accommodations while receiving TDIU. Good records make each questionnaire easy to answer accurately and give you proof that your work stayed within the marginal or sheltered rules if the VA ever questions it.

09
Where to go from here

Respond to any TDIU employment questionnaire accurately and on time, frame any work as marginal or sheltered where that is true, and keep your own records so you can support your answers.
