Part VIII, Subpart iv, Chapter 3, Section BIndividual Unemployability (IU) Claims Development

Revised September 25, 2025

VIII.iv.3.B.1.a#General Evidence Requirements in IU Claims

A decision concerning entitlement to a total disability evaluation based on individual unemployability (IU) in accordance with 38 CFR 3.340, 38 CFR 3.341(a), and 38 CFR 4.16 is based on a review of all available evidence, which should be sufficient to evaluate the

• current severity of the service-connected (SC) disability(ies) that the Veteran states and/or the evidence indicates prevent(s) substantially gainful employment
• the impact of SC disability(ies) upon employability, and
• employment status.

Development of the claim must be targeted at gathering all evidence concerning economic and non-economic factors affecting employability, including but not limited to evidence concerning the Veteran’s

• current employment status
• past employment history
• educational/training history, and
• functional impairment arising from SC disabilities as shown by
  • examinations
  • Department of Veterans Affairs (VA) or private medical evidence, and
  • lay evidence.

Reference: For more information on within scope determinations, see M21-1, Part V, Subpart ii, 3.A.2.

VIII.iv.3.B.1.b#Determining Whether IU is an Issue in a Claim

While a substantially complete VA Form 21-8940, Veteran’s Application for Increased Compensation Based on Unemployability , is necessary to provide VA with information needed to substantiate entitlement to IU, it is not necessary to raise the issue of IU.

VIII.iv.3.B.1.c#Development for VA Form 21-8940

Forward a VA Form 21-8940 to the Veteran if the form has not been received but a request for IU is

• expressly raised by the Veteran, or
• reasonably raised by the evidence of record.

Important:

• When written communication or other evidence indicates the Veteran cannot work because of SC disabilities and a standard application for benefits with a specific claim for IU has not been received, but the criteria to consider the information a reasonably raised claim has not been met due to the Veteran’s disabilities not meeting the schedular criteria specified under 38 CFR 4.16(a), follow the request for application procedures at M21-1, Part II, Subpart iii, 2.G.1.
• A Veteran’s statement of loss or termination of employment can only reasonably raise a claim for IU if the Veteran indicates that termination was due to an SC disability.

References: For more information on required

• employment history, see M21-1, Part VIII, Subpart iv, 3.B.3, and
• disability information, see M21-1, Part VIII, Subpart iv, 3.B.1.e.

VIII.iv.3.B.1.d#Requirement for VA Form 21-8940

A substantially complete VA Form 21-8940 is required to establish entitlement to IU because it gathers relevant and indispensable information regarding a claimant’s disabilities and employment and educational histories. The form concludes with a series of sworn certification statements, and in endorsing it, a Veteran

• attests to employment status, and
• signals understanding of the IU benefit’s incompatibility with substantially gainful work.

A properly signed and executed VA Form 21-8940 enables VA to gather the information necessary to determine the Veteran’s entitlement to IU and recover IU compensation that is later discovered to have been awarded on fraudulent terms. Important:

• If the issue of IU is raised by the Veteran or reasonably raised by the evidence of record and the only VA Form 21-8940 of record was received as part of a finally adjudicated claim, a new VA Form 21-8940 must be provided to the Veteran.
• A VA Form 21-8940 must be signed by the Veteran and not a third-party source such as a power of attorney.

Reference: For more information on criteria for substantially complete applications, see M21-1, Part II, Subpart iii, 1.C.

VIII.iv.3.B.1.e#Veteran’s Responsibility to Specify a Disability or Disabilities That Cause Unemployability

A request for a total disability evaluation on the basis of unemployability, whether expressly raised by the Veteran or reasonably raised by the record, is not a separate claim for benefits. Rather, the IU claim involves an attempt to obtain an appropriate rating for a disability or disabilities, either as part of the initial adjudication of a claim or as a part of a claim for increased compensation if the disability upon which IU is based has already been found to be SC. As noted in M21-1, Part II, Subpart iii, 1.A.1.a, VA Form 21-8940 is not a standard claim form for entitlement to an increased evaluation or service connection (SC) for a disability listed on that form. A claim for IU, however, may not be freestanding and must be associated with the evaluation of a current SC condition or an initial request for SC for the underlying disabilities claimed to cause unemployability.

• As part of a substantially complete application for IU, VA requires that a claimant with multiple SC disabilities specify at least one disability that causes the unemployability.
• VA will address the evaluation of all SC disabilities claimed to cause unemployability as a part of the claim for entitlement to IU.

Use the table below to determine the appropriate action to take based on whether the Veteran specifies a disability as the cause of unemployability.

Important: When a claim for entitlement to IU is successfully withdrawn, as discussed in M21-1, Part II, Subpart iii, 2.F, all issues associated with IU claim as listed on VA Form 21-8940 are also considered withdrawn unless the issue was specifically claimed on an appropriate standard form for that claim or contention type.

Reference : For more information on the status of an IU claim relative to the underlying disabilities, see Rice v. Shinseki, 22 Vet.App. 447 (2009).

VIII.iv.3.B.1.f#Identifying Reasonably Raised Claims of IU

Reasonably raised claims of IU may arise

• during the processing of a
  • claim
  • decision review request under 38 CFR 3.2500, or
  • legacy appeal, or
• as a result of a routine future examination.

VA must consider a claim for IU if

• the Veteran’s SC rating meets the minimum schedular criteria found in 38 CFR 4.16(a), and
• there is current evidence of unemployability due to an SC disability(ies) in the Veteran’s claims folder or under VA control.

Reference: For more information on reasonably raised claims for IU, see

• Norris v. West, 12 Vet.App. 413 (1999)
• Roberson v. Principi, 251 F.3d 1378 (Fed. Cir. 2001), and
• Comer v. Peake, 552 F.3d 1362 (Fed. Cir. 2009).

VIII.iv.3.B.1.g#Developing Reasonably Raised Claims of IU

When a reasonably raised claim of IU is deferred by the rating activity, develop the reasonably raised IU issue under the existing end product, which will remain pending until a merits determination of IU entitlement is made.Request completion of a new VA Form 21-8940 if

• a VA Form 21-8940 is not of record, or
• the only VA Form 21-8940 of record was received as part of a finally adjudicated claim.

When determining whether Section 5103 notice is required for the claim, refer to M21-1, Part III, Subpart i, 2.B.1.b-d.Important:

• When development for a reasonably raised claim of IU is incorporated within a decision notice letter, ensure that the claimant is informed of the time periods within which the evidence must be submitted.
• Upon receipt of a completed VA Form 21-8940 in response to the development described above, claims processors should determine if the existing medical evidence, to include any disability benefits questionnaire (DBQ) previously requested by VA or completed by a private provider, is sufficient to reflect the current severity of the SC condition(s) claimed as causing unemployability.
  • If the existing evidence is sufficient (which is likely if the rating activity recently made a decision on evaluation of the condition(s)), refer the claim to the rating activity for a decision on the deferred issue of IU.
  • If the existing evidence is not sufficient,
    • request an examination for the condition(s), and
    • select the EMPLOYMENT IMPACT ASSESSMENT REQUESTED? field in VBMS.

Reference: For more information on sufficient medical evidence and the need for an examination in IU claims, see M21-1, Part VIII, Subpart iv, 3.B.2.a and b.

2Medical Evidence in Support of IU Claims

This topic contains guidance on medical evidence requirements in IU claims, including

• medical evidence and examination requirements in IU claims, and
• requesting an examination in IU claims.

Revised September 25, 2024

VIII.iv.3.B.2.a#Medical Evidence and Examination Requirements in IU Claims

A claim for IU must contain sufficient medical evidence to

• support a current evaluation of the SC disabilities alleged by the claimant to be causing unemployability, and
• indicate how functional impairments caused by those SC disabilities impact employment activities.

The evidence should reflect the Veteran’s condition within the past 12 months and include, but need not be limited to

• the results of VA examination(s)
• hospital reports, and/or
• outpatient treatment records.

Important: A medical examination is not automatically required in every IU claim. An examination, including a request for an employment impact assessment as discussed in M21-1, Part VIII, Subpart iv, 3.B.2.b, is required if the information and evidence of record do not contain sufficient competent medical evidence to decide the claim.

VIII.iv.3.B.2.b#Requesting an Examination in IU Claims

When an examination is necessary, it is normally sufficient to request condition-specific DBQs for the conditions alleged to cause unemployability on the VA Form 21-8940 (for example, joints, mental, and peripheral nerves DBQs). Schedule a general medical examination only if the rating activity determines that it is needed to fairly and fully adjudicate the IU claim, such as when the claim is made in connection with original claims for disability compensation or where it is alleged that multiple SC and/or NSC disabilities may have an impact on employability. However, do not order examinations for disabilities not alleged to cause or contribute to unemployability, even if the Veteran has received a previous award of SC for the disabilities. Do not ask the examiner to opine as to whether or not the Veteran is “unemployable” due to the indicated SC disabilities. A determination that a Veteran is unemployable is a legal determination that rests solely with the rating activity. Instead, request that the examiner

• comment on the Veteran's ability to function in an occupational environment, and
• describe functional impairment caused solely by the SC disabilities.

Note: The language generated upon selection of the EMPLOYMENT IMPACT ASSESSMENT REQUESTED? field when requesting an examination through VBMS is legally sufficient to elicit the information necessary to adjudicate the issue of IU. References: For more information on

• adjudicative determinations in IU claims, see 38 CFR 4.16
• avoiding asking for legal conclusions in medical opinions, see M21-1, Part IV, Subpart i, 2.A.7.j, and
• considering sedentary employment in claims for IU, see Withers v. Wilkie, 30 Vet.App. 139 (2018).

3Employment-Related Development in IU Claims

This topic contains information on employment-related development in IU claims, including

• employment history requirements in IU claims
• action to take based on employment history provided
• requesting employment information from employers, and
• self-employment development.

Revised July 29, 2021

VIII.iv.3.B.3.a#Employment History Requirements in IU Claims

_VA Form 21-8940 requires an employment history for the last five years that the Veteran worked. In determining whether the Veteran provided work history information for the required time period, review the entries in Blocks 14 and 15 on the VA Form 21-8940. **Note: _** The minimum required work history, for the purpose of requesting employment information from the Veteran’s employer(s), must include the last year of employment.
Important: If the Veteran fails to provide employment history, the evaluation of the underlying issues claimed to cause unemployability must still be adjudicated even though the claim for IU may result in denial.

VIII.iv.3.B.3.b#Action to Take Based on Employment History Provided

Use the table below to determine the appropriate action to take based on whether the Veteran provides the required work history on VA Form 21-8940.

VIII.iv.3.B.3.c#Requesting Employment Information From Employers

Development for VA Form(s) 21-4192, Request for Employment Information in Connection With Claim for Disability Benefits, is routinely initiated at the time a claim for IU is received via submission of VA Form 21-8940. Use the table below to request VA Form(s) 21-4192, for the Veteran’s last year of employment even if the Veteran

• has not worked for five years or more, or
• is or may be currently employed, as marginal employment is possible.

Exceptions:

• When the evidence of record clearly warrants a grant of entitlement to IU, do not delay a rating decision granting entitlement to IU for initial or continued development for VA Form 21-4192.
• Do not send the VA Form 21-4192 to a previous employer if the Veteran states that the employer is no longer in business or other evidence indicates the business is closed.
• Do not send the VA Form 21-4192 when the Veteran reports self- employment. Follow the procedures at M21-1, Part VIII, Subpart iv, 3.B.3.d for development regarding self-employment.

Notes:

• If the information on VA Form 21-4192 only states that the Veteran retired, then request additional information as to whether the Veteran’s retirement was by reason of disability. If so, ask the employer to identify the nature of the disability for which the Veteran was retired.

• Do not deny an IU claim solely because an employer failed to return a completed VA Form 21-4192.

• If the Veteran worked for a federal agency, treat the VA Form 21-4192 development as a request for federal records and follow the guidelines prescribed under M21-1, Part III, Subpart ii, 1.A.1.c.

• If an employer responds to the VA Form 21-4192 by providing a website that does not provide all the required information in the form, follow-up with the employer and again request that the VA Form 21-4192 be completed, allowing an additional 10 days for response.

VIII.iv.3.B.3.d#Self-Employment Development

Development to produce the evidence necessary to establish the degree to which an SC disability has impaired the Veteran’s ability to engage in self-employment must generally be more extensive than development in cases in which the Veteran worked for others. Request that the Veteran furnish a statement regarding the

• types of work performed
• number of hours worked per week, and
• amount of time lost in the previous 12 months due to SC disabilities.

4Other IU Development Procedures

This topic contains other development procedures for IU claims, including

• when to obtain Social Security Administration (SSA) records in IU claims
• when to obtain vocational rehabilitation/employment (VR&E) records in IU claims, and
• considering IU claims for National Guard and reservists.

Revised September 25, 2025

VIII.iv.3.B.4.a#When to Obtain SSA Records in IU Claims

Obtain and consider complete copies of the Social Security Administration (SSA) decision (awards and denials) and any supporting medical records when

• evidence of record is insufficient to award IU, and
• evidence of a past or present claim for and/or award of disability benefits by SSA is shown in
  • the Veteran’s claims folder, or
  • any VA system including, but not limited to, VBMS (using the SSA INQUIRY function).

Notes:

• Although decisions by SSA regarding a Veteran’s unemployability are not controlling for VA determinations, SSA’s record may indicate the level of impairment of the Veteran’s SC disability.
• When reviewing SSA records, pay close attention to what disability resulted in an award of SSA benefits, and whether that disability is one for which SC has been awarded.
• Regional offices (ROs) are not required to request SSA records when a Veteran fails to return the VA Form 21-8940.

References: For more information on

• requesting information from SSA, see M21-1, Part III, Subpart ii, 1.B, and
• the effect of SSA decisions regarding unemployability on VA determinations, see Murincsak v. Derwinski, 2 Vet.App. 363 (1992).

VIII.iv.3.B.4.b#When to Obtain VR&E Records in IU Claims

Evaluate any already existing records of Veteran Readiness and Employment (VR&E) Service consultation

• when the evidence indicates that the Veteran underwent VR&E consultation sometime in the past related to a prior vocational rehabilitation/employment (VR&E) claim, such as (but not limited to)
  • a Veteran’s report of participation in the VR&E program
  • a CH31 Rehabilitation Folder (R&E) shown on the FOLDER LOCATION page in VBMS Core
  • VA Form 28-1900, Application For Veteran Readiness And Employment Benefits For Claimants With Service-Connected Disabilities , included in the claims folder, and/or
  • Chapter 31 payments shown on the CURRENT AND HISTORICAL AWARD INFORMATION page and FINANCIAL INFORMATION page in VBMS Core
• when the evidence of record is insufficient to award IU, and
• without regard to the period of time that has passed since the VR&E consultation occurred and records were created.

The VR&E records may

• document the Veteran’s participation in a training program, or
• show that training was not feasible or was unsuccessful.

Notes:

• The entire Counseling/Evaluation/Rehabilitation (CER) folder is not necessary to adjudicate IU claims that are processed at the RO. If adjudicating a claim for IU, and the Veteran has an existing VR&E record, a completed VA Form 28-1902b, Counseling Record – Narrative Report, and VA Form 28-1902f, Feasibility Determination—Narrative Report, need only be in the record in lieu of the entire CER folder. VA Form 28-1902b and VA Form 28-1902f contain the necessary information concerning the impact of the Veteran’s SC and NSC conditions on employability.
• The entire CER folder must be of record when adjudicating Board of Veterans’ Appeals (BVA) remands.
• ROs are not required to request VR&E records when a Veteran fails to return the VA Form 21-8940.

Reference: For more information on the procedure for obtaining VR&E records, see M21-1, Part III, Subpart ii, 1.A.1.f.

VIII.iv.3.B.4.c#Considering IU Claims for National Guard and Reservists

If a Veteran is currently serving in the National Guard or Reserves, the reviewer should

• determine if a medical examiner has indicated that the Veteran is unable to perform military duties due to an SC disability(ies), and
• make sure that the latest service treatment records are of record, as such records may aid in determining if the disability is preventing the Veteran from performing current National Guard or reserve duties.

If the evidence of record is not sufficient to award increased compensation based on IU, request that the unit commander complete and return VA Form 21-4192._ _Note: The VBMS Initial Private 3rd Party Employer Letter, 21-4192 does not allow the user to edit the salutation section of the letter. To ensure that the request is routed to the unit commander, include “ATTN Unit Commander” in the Employer Name section following the unit designation. Example: 334th Brigade Engineer Battalion ATTN Unit Commander
