    Last updated: 2026-08-21
    General education only. This page describes how VA generally evaluates these claims under federal regulations. It is not legal advice and is not a recommendation about any individual claim. Every veteran's facts and evidence are different — for guidance on a specific situation, speak with a VA-accredited representative.

    The forms

    • , 's Application for Increased Compensation Based on Unemployability — the application, covering the last five years of work history and education.
    • VA Form 21-4192, Request for Employment Information in Connection with for Disability Benefits — sent to former employers for dates, duties, concessions, and reason for leaving.
    • VA Form 21-4140, Employment Questionnaire — historically used for periodic certification of continued unemployability.
    • Income data matching with IRS and SSA records, which is what most commonly triggers a review.

    Marginal and protected employment

    38 CFR § 4.16(a) states that marginal employment is not . Marginal employment generally exists when earned annual income does not exceed the Census Bureau poverty threshold for one person. It also exists, on a facts-found basis, where employment is in a protected environment such as a family business or sheltered workshop, regardless of the amount earned.

    Accommodations matter to the analysis: reduced hours, unscheduled absences, a supervisor absorbing tasks, or work performed from home because of the disability all bear on whether employment is truly gainful. Cantrell v. Shulkin, 28 Vet. App. 382 (2017), addresses how sheltered or accommodated work is assessed.

    If a former employer never responds

    A 21-4192 is a request, not an obligation the controls. VA's under 38 CFR § 3.159 covers making reasonable efforts to obtain it, and where the employer does not respond, the is decided on the rest of the record — work history, tax records, treatment evidence, and lay statements. A missing employer response is not a permissible reason to deny or discontinue on its own.

    What income is not employment income

    • Retirement or pension payments, including disability retirement.
    • Social Security Disability Insurance or SSI benefits.
    • A spouse's income appearing on a joint tax return.
    • Severance, accrued leave payout, or a one-time distribution reported in the year received.
    • Passive income from investments or rental property, which is not employment.

    Fee rules

    An accredited agent or attorney may charge a fee only for work performed after VA issues a decision on the (38 U.S.C. § 5904(c)(1); 38 CFR § 14.636(c)). Fees must be reasonable, disclosed in writing, and filed with VA. Nothing here predicts an outcome in any individual case.
