VA Form 21-526EZ Walkthrough: Section-by-Section Guide
TL;DR. VA Form 21-526EZ is the primary application for VA disability compensation. The form has thirteen sections covering identification, claim information, current health, medical records (federal and private), claim type, Fully Developed Claim certification, additional remarks, witness statement, direct deposit, and signature. Two sections matter disproportionately: Section X (additional remarks) is where the veteran articulates the service-connection theory, and Section IX is the optional Fully Developed Claim certification that trades faster processing for veteran-side records gathering. The most common filing errors are leaving Section X blank, failing to list private records in Section VII, and not signing Section XIII under penalty of perjury.
Form context and history
The 21-526EZ replaced VA Form 21-526 in 2013 as part of a VA effort to simplify the initial claim filing process. The older form ran 23 pages and required cross-references to multiple supplemental forms (21-22 for representation, 21-686c for dependents, others). The EZ version consolidates the core claim information into one form and removes redundant questions.
The current form (as of mid-2026) is roughly 13 pages and is available as a fillable PDF at VA.gov or as an online filing wizard. Most veterans should use the online wizard rather than the paper PDF; the wizard handles section navigation, auto-populates known fields, and provides upload slots for evidence attachments.
Section I: Identification
Veteran name, Social Security number, VA file number (if any), date of birth, sex, service number (if pre-1972), and contact information. Most fields auto-populate from VA.gov account data if filing online.
The VA file number is the unique identifier the VA assigns to a veteran's claim record. For veterans who have never filed before, the field is left blank and the VA assigns a number upon claim receipt. For veterans filing a supplemental claim or increase, the existing file number is required.
Section II: Claim information
Active-duty status, current military status (active, reserve, separated, retired), branches served, and dates of service. For each branch, the veteran lists service entry date, separation date, and character of service (honorable, general, etc.). Veterans with multiple service periods (active duty, then Reserve, then active duty again) list each period.
Character of service matters because dishonorable discharges and certain bad-conduct discharges create a statutory bar to VA benefits under 38 CFR 3.12. Veterans with other-than-honorable discharges should consult an accredited representative before filing because a Character of Discharge determination may be required.
Section III: Claims information continued — conditions claimed
The list of disabilities being claimed. Each condition gets its own line: name of condition, when it began, whether it began during service or as a result of service, and whether the condition is related to a previously service-connected condition (a secondary claim).
Best practice: list each condition with a specific medical term plus the side or location. Not "knee pain" but "right knee instability and degenerative joint disease." Not "back" but "lumbar spine degenerative disc disease at L4-L5." The rater uses these descriptions to map the condition to a Diagnostic Code in the rating schedule. Vague descriptions invite vague C&P exams.
For secondary claims, name the primary service-connected condition: "Sleep apnea secondary to service-connected PTSD" or "Right hip strain secondary to service-connected left knee instability with altered gait."
Section IV: Current health
Current treatment status: who is treating the veteran for each claimed condition, when treatment began, and the treating facility. If the VA is providing care, the veteran lists the VA medical center. If private providers are treating, the veteran lists names and addresses.
This section primes the rater's evidence-gathering path. A claimed condition with no current treatment is harder to rate because the C&P examiner cannot reference recent treatment records.
Section V: Recent VA medical records
VA facilities where the veteran has received care since separation. The VA system pulls these records automatically — the veteran does not need to attach them — but listing the facilities accelerates the records-pull and prevents records from being overlooked.
Section VI: Federal records the VA should request
Records held by other federal agencies the VA needs to request on the veteran's behalf. Common examples: Department of Defense service treatment records (if not already in the VA system), Social Security Administration disability records (if the veteran has applied for or receives SSDI), Office of Personnel Management records (federal-employee medical records), and Department of Labor (FECA-injury records).
The VA has a duty to assist under 38 CFR 3.159, and that duty includes requesting federal records identified by the veteran. Leaving Section VI blank when federal records exist is a common error that delays the claim.
Section VII: Private medical records
Records held by non-federal providers — civilian doctors, hospitals, clinics, urgent care, chiropractors, psychologists. Unlike federal records, the VA does not have an automatic right to request private records. The veteran has two options:
- Veteran obtains and submits. Request records from each provider, scan, and upload as attachments to the claim. Faster.
- VA requests on veteran's behalf. List each provider in Section VII and authorize the VA to request via VA Form 21-4142 (Authorization to Disclose Information). Slower because the VA's records request gets queued behind thousands of others.
For a Fully Developed Claim (Section IX), the veteran must use Option 1 — submit all private records with the claim. Listing private records in Section VII without submitting them excludes the claim from FDC processing.
Section VIII: Claim type
Original (first-ever claim for this condition), supplemental (re-opening a previously denied claim with new evidence), increase (existing service-connected condition that has worsened), secondary (a new condition caused or aggravated by an existing service-connected condition), or pre-discharge (BDD or Quick Start). Selecting the correct type routes the claim to the appropriate processing queue.
Section IX: Fully Developed Claim certification
Optional certification. By checking the FDC box, the veteran asserts that all evidence supporting the claim is being submitted with the form and that the VA need not conduct additional records development. FDC claims are processed on a faster track, typically 90 to 125 days versus 150 or more for standard claims.
FDC requires veteran-side records gathering: all private medical records, lay statements, and nexus letters must be uploaded with the claim. The VA still conducts its own C&P exams and pulls VA and federal records. If the VA later discovers additional private records exist that the veteran did not submit, the claim is removed from the FDC track.
When to skip FDC: complex claims with multiple secondary conditions, claims where the veteran cannot obtain certain private records, or claims where waiting for records would push the filing past a critical effective-date deadline.
Section X: Additional remarks
The most underused section on the form. Section X is open-text and is the veteran's chance to direct the rater's analysis. Recommended content:
- The service-connection theory for each condition: direct, presumptive (cite the specific 38 CFR section), aggravation, or secondary.
- Specific in-service events with dates and locations (especially for conditions where STRs are silent).
- List of attachments: nexus letters, lay statements (21-4138 or 21-10210 forms), buddy statements, photographs, MOS documentation, deployment orders.
- For supplemental claims: a direct response to the prior denial reason. If the rater previously denied for "no nexus," Section X identifies the new nexus letter attached.
- For presumptive claims: cite the specific presumptive provision (Camp Lejeune water under 38 CFR 3.307(a)(7), Agent Orange under 38 CFR 3.309(e), Gulf War undiagnosed illness under 38 CFR 3.317, PACT Act burn pit conditions under 38 USC 1119, and others).
A blank Section X leaves the rater to guess at the veteran's theory. A two-page Section X with citations and attachment lists frequently shifts borderline claims toward grant.
Section XI: Witness statement
Used only if a witness has personal knowledge of the in-service event being claimed (a buddy who saw the IED ambush, a unit member who observed the chemical exposure, a spouse who witnessed the post-deployment symptom onset). The witness signs this section, or attaches a separate VA Form 21-10210 (Lay/Witness Statement) for more space.
Section XII: Direct deposit
Bank routing and account information for VA benefits deposits. Direct deposit is required for federal benefit payments per 31 USC 3332.
Section XIII: Certification and signature
The veteran's signature under penalty of perjury per 28 USC 1746. The signature certifies that the statements in the form are true. False statements expose the veteran to loss of benefits, recovery of overpayments, and criminal prosecution under 18 USC 1001.
The veteran must personally sign. Accredited representatives can prepare the form and represent the veteran throughout the claim, but they cannot sign the certification. Online filing satisfies the signature requirement through VA.gov digital signature.
Common filing mistakes
| Section | Common error | Correction |
|---|---|---|
| III | Vague condition descriptions ("back pain", "knee") | Specific medical terms with side/location ("lumbar DDD L4-L5", "right knee instability") |
| VI | Blank when federal records exist (SSA, DoD, OPM) | List each federal agency with relevant records |
| VII | Blank when private records exist | List private providers; either submit records or sign 21-4142 |
| VIII | Wrong claim type selected | Match claim type to actual situation (original vs supplemental vs increase) |
| IX | FDC checked but private records not submitted | Uncheck FDC, or gather and submit all private records first |
| X | Left blank | Articulate service-connection theory, cite 38 CFR provisions, list attachments |
| XIII | Unsigned or representative-signed | Veteran personal signature required |
Worked example
Air Force veteran, 8 years service, separated 2020. Files initial claim April 2026 online via VA.gov.
Claimed conditions: (1) lumbar spine DDD secondary to in-service flight-line ground crew duties; (2) bilateral tinnitus from flight-line noise; (3) sleep apnea secondary to service-connected (claimed) PTSD; (4) PTSD from a 2017 vehicle-borne IED incident in Afghanistan.
Section III entries. Veteran writes specific terms: "Degenerative disc disease, lumbar spine, L5-S1, with bilateral lower extremity radiculopathy"; "Tinnitus, bilateral, constant, onset 2018"; "Obstructive sleep apnea, diagnosed 2024, requires CPAP, claimed as secondary to PTSD"; "Post-traumatic stress disorder, related to 2017 IED incident, Bagram-Kabul road convoy".
Section VI entries. Veteran lists Department of Defense (for complete STR), and Department of Veterans Affairs (for 2024 sleep study at Tampa VA).
Section VII entries. Veteran lists civilian psychologist who has been treating PTSD since 2022 (Dr. Smith, address). Veteran signs VA Form 21-4142 authorizing the VA to request these records.
Section IX. Veteran does NOT check FDC because private psychology records have not yet been obtained.
Section X (additional remarks). Veteran writes a structured statement: (a) Lumbar DDD — direct service connection via Section X-attached buddy statement from Senior Master Sergeant Johnson describing flight-line ground crew duties and back complaints during 2014-2018 assignment. Also attached: civilian spine MRI from 2025. (b) Tinnitus — direct service connection under in-service noise exposure documented by AFSC 2A6X1 (Aerospace Propulsion). MOS itself supports noise exposure presumption. (c) Sleep apnea — secondary to PTSD per attached nexus letter from sleep medicine physician Dr. Chen. (d) PTSD — direct service connection from 2017 IED incident documented in attached Combat Action Badge orders and lay statement from convoy commander Captain Rivera.
Section XIII. Veteran signs digitally via VA.gov.
Result. The structured Section X gave the rater a clear roadmap. The rater scheduled four C&P exams. All four conditions were service-connected on the first decision: lumbar DDD 20%, tinnitus 10%, sleep apnea 50%, PTSD 70%. Combined per 38 CFR 4.25: 90%. Effective date: April 2026 filing date.
