How to File a VA Disability Claim: Step-by-Step for 2026

Quick Answer: File a VA disability claim using VA Form 21-526EZ at VA.gov. Before you file, submit an Intent to File to lock in your effective date for up to one year. Gather a current diagnosis, evidence of an in-service event, and a nexus opinion connecting the two. VA will schedule a C&P exam at no cost.

Is filing an initial disability claim the right step for your situation?

• Do you have a current medical diagnosis for the condition you want to claim?
  • Yes: Proceed to gather evidence of the in-service event or exposure
  • No: Get a diagnosis from a qualified provider before filing; VA does not compensate conditions without a current diagnosis
• Do you have documentation of an in-service event, injury, or exposure that could have caused or contributed to the condition?
  • Yes: Proceed; the documentation may be in your service treatment records, personnel records, or buddy statements from fellow service members
  • No: File an Intent to File now to protect your effective date while you locate records through the National Personnel Records Center or obtain buddy statements
• Have you already received a VA decision on this condition that you want to challenge?
  • Yes: A supplemental claim or higher-level review is the correct path, not a new initial claim; see the supplemental claim article below
  • No: File an initial claim using VA Form 21-526EZ

This is a general procedural guide. An accredited VSO or veterans law attorney can evaluate your specific evidence situation.

The Three Requirements for Service Connection

The Court of Appeals for Veterans Claims established the framework in Caluza v. Brown, 7 Vet. App. 498 (1995). Service connection requires three elements, all present simultaneously:

A current diagnosis of the condition being claimed. VA does not compensate symptoms without a diagnosis, and it does not compensate conditions that no longer exist. The diagnosis must come from a medical professional qualified to diagnose the specific condition.

An in-service event, injury, or exposure that could have caused or contributed to the condition. This does not need to be a single traumatic event. Cumulative occupational exposure, environmental hazards, and chronic physical demands all qualify. The event may be documented in service treatment records, personnel records, commander’s reports, or buddy statements from fellow service members.

A nexus connecting the in-service event to the current diagnosis. A VA Compensation and Pension examiner provides this opinion automatically during the claims process. A private nexus letter from a treating physician or specialist carries equal legal weight when submitted as evidence.

Missing any one of these three elements is the most common reason VA denies claims on the merits.

Step 1: File an Intent to File

Before submitting the full claim form, file an Intent to File under 38 CFR § 3.155. This notifies VA that you intend to file a claim for a specific condition. It does not require medical records or evidence at the time of filing.

The Intent to File locks in a potential effective date. If VA grants the claim within one year of the Intent to File date, back pay runs from the date of the Intent to File, not the date you submitted VA Form 21-526EZ. At 50 percent compensation with no dependents in 2026, one year of back pay is approximately $13,212. Filing the Intent to File before your evidence package is assembled costs nothing and preserves that effective date.

Submit an Intent to File:

• Online at VA.gov (fastest, creates an immediate timestamped record)
• By phone at 1-800-827-1000
• Through an accredited VSO representative
• In person at a VA regional office

The Intent to File expires one year after submission. File VA Form 21-526EZ before the expiration date or you lose the protected effective date.

Step 2: Gather Required Evidence

Service treatment records and personnel records. These document the in-service event. Request them through the National Personnel Records Center (NPRC) if they are not already in VA’s system. VA’s duty to assist requires VA to request these records on your behalf under 38 CFR § 3.159, but requesting them directly and submitting them with the claim is faster and more reliable.

Current medical records. Records from treating physicians, specialists, and VA healthcare providers showing the current diagnosis and severity. If your condition has been treated at VA facilities, those records are accessible to VA raters. Records from private providers must be submitted by the veteran.

Buddy statements (VA Form 21-10210). Written statements from fellow service members, family members, or others who witnessed the in-service event or who have observed the condition’s impact. These are admissible lay evidence under 38 CFR § 3.303(a). Buddy statements are particularly useful when the in-service event was not formally documented at the time it occurred.

A nexus opinion. The C&P exam will produce one automatically. A private nexus letter from a treating physician or specialist can be submitted with the initial claim to provide a favorable nexus opinion before the VA examiner’s opinion is issued. Under 38 CFR § 3.102, the nexus opinion must state that the condition is at least as likely as not caused or aggravated by military service.

Step 3: Submit VA Form 21-526EZ

VA Form 21-526EZ is the Application for Disability Compensation and Related Compensation Benefits. It records the conditions being claimed, the relevant service history, and the evidence being submitted.

Online filing at VA.gov is the preferred method. It generates immediate confirmation, creates a timestamped record of submission, and routes directly to VA’s processing system. Supporting documents can be uploaded at the time of filing.

Mail submission goes to the Evidence Intake Center in Janesville, Wisconsin. Allow additional processing time for mail transit and intake. Use certified mail with return receipt when submitting paper records.

In-person submission at a VA regional office allows a VSO or VA staff member to review the package before submission and can surface missing elements before the claim is formally received.

A Fully Developed Claim (FDC) is an option within VA Form 21-526EZ. Checking the FDC box indicates that you have submitted all known relevant evidence and are not requesting additional VA development. FDC claims can process faster, but if you are uncertain whether all relevant records have been located, a standard claim preserves VA’s full duty to assist obligations.

Step 4: VA’s Duty to Assist

After receiving a claim, VA must fulfill its duty to assist under 38 CFR § 3.159. This requires VA to:

Request relevant records from federal agencies, including the Department of Defense, National Personnel Records Center, Social Security Administration, and other VA facilities.

Notify the veteran when VA cannot locate records and advise on what evidence the veteran can obtain independently.

Schedule a Compensation and Pension examination if VA determines one is needed to evaluate any claimed condition, at no cost to the veteran.

The duty to assist applies to initial claims and supplemental claims. It does not apply in the higher-level review lane or at the Board of Veterans’ Appeals.

Step 5: The C&P Exam

VA schedules a Compensation and Pension exam for most claimed conditions. The examiner reviews available records and produces a Disability Benefits Questionnaire (DBQ) that includes a nexus opinion and severity assessment for each condition.

Attendance is mandatory. Under 38 CFR § 3.655, failure to report for a scheduled C&P exam without good cause results in a denial for the condition tied to that exam. Contact VA immediately if you cannot attend. VA will reschedule with advance notice and a stated reason.

Prepare for the exam. Bring copies of relevant records, including any private medical records or nexus letters you have obtained. The examiner must review your records to produce a legally adequate opinion. Under Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008), a C&P exam is inadequate if the examiner fails to review relevant records and explain the basis for the nexus opinion. An inadequate exam is grounds for requesting a new examination.

Request a copy of the DBQ. After the exam, you can obtain a copy through VA.gov or by calling 1-800-827-1000. If the examiner’s opinion is negative or lacks adequate reasoning, that specific deficiency can be the basis for a supplemental claim with a private nexus letter.

Reading the Rating Decision

VA issues a written rating decision addressing each claimed condition. The decision states:

Whether service connection was granted or denied for each condition, and the specific reason for denial if applicable.

The rating percentage assigned to each service-connected condition.

The combined disability rating under 38 CFR § 4.25.

The monthly compensation amount and the effective date.

The rating decision includes notice of appeal rights and the options under the Appeals Modernization Act: supplemental claim, higher-level review, or Board of Veterans’ Appeals. The one-year clock for each option runs from the date of the decision.

If the decision denies service connection based on an inadequate C&P exam, or if new medical evidence is available that was not in the file, a supplemental claim with a private nexus letter is the next step. If the decision appears to misapply evidence that was already in the file, a higher-level review is the faster path.

Governing Authority

Governing authority: 38 CFR § 3.155 (intent to file); 38 CFR § 3.159 (duty to assist); 38 CFR § 3.160 (applications for benefits); 38 CFR § 3.655 (failure to report for examination); 38 CFR § 3.102 (benefit of the doubt, at-least-as-likely standard); 38 U.S.C. § 5103 (notice of required information); 38 U.S.C. § 5103A (duty to assist claimants)

Controlling case law: Caluza v. Brown, 7 Vet. App. 498 (1995), three elements required for service connection; Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008), C&P exam is legally inadequate when the examiner fails to review relevant records and explain the basis for the opinion
