VA Intent to File: Effective Date, Form 21-0966, and Deadline

A VA intent to file is a short notice you give the Department of Veterans Affairs that you plan to apply for benefits, and it locks in the date the VA will use to start your back pay if your claim is later approved. Under 38 C.F.R. § 3.155, if you submit a complete claim within one year of your intent to file, the VA treats the claim as though you filed it on the day the intent to file arrived.¹ Filing it takes minutes. Skipping it can cost thousands.

At a 50% disability rating with no dependents, VA compensation runs $1,132.90 per month in 2026.² A six-month gap between when you could have filed an intent and when you actually submit a completed application erases nearly $6,800 in back pay you cannot recover. Higher ratings lose more.

How the Intent to File Sets Your Effective Date

Your effective date is the day the VA begins calculating what it owes you. Without an intent to file, that date is whenever the VA receives your completed application package. With one, the clock can start up to a year earlier. That’s the whole point of the mechanism: it gives you time to gather medical records, service documents, and supporting evidence without losing any of the money you would have been entitled to on day one.

Which Benefits It Covers

The intent to file process applies to three categories of VA benefits:³

Disability compensation for injuries or illnesses connected to military service.
Pension benefits, including special monthly pension categories like Aid and Attendance and Housebound benefits, for wartime veterans with limited income.
Dependency and Indemnity Compensation (DIC) for surviving spouses, children, or parents of veterans who died from a service-connected condition or on active duty.

Each category needs its own intent to file. If you plan to apply for both compensation and pension, check both boxes on the form and the VA will create two separate active intents. You can only have one active intent to file per benefit type at a time, and submitting a second one while the first is still active does not reset your one-year clock.

Three Ways to Submit It

All three channels carry the same legal weight under 38 C.F.R. § 3.155.¹ Pick whichever one you can complete today.

Online at VA.gov

Signing in to VA.gov and starting a disability compensation application is the fastest route. The moment you save a partially completed application, the VA sets your intent to file date automatically, even if you don’t submit the finished form for months.⁴ The electronic timestamp removes any argument later about when the VA received your notice.

By Phone

Call 800-827-1000 (TTY: 711), Monday through Friday, 8:00 a.m. to 9:00 p.m. Eastern.³ Tell the representative you want to establish an intent to file. They will record it and note the date in your file. Write down the date, the representative’s name, and any confirmation number before you hang up.

By Mail or In Person

Download VA Form 21-0966, fill it out, and mail it to:

Department of Veterans Affairs
Evidence Intake Center
P.O. Box 4444
Janesville, WI 53547-4444⁵

You can also hand-deliver the form to your nearest VA regional office. Ask staff to stamp your copy with the receipt date. If you mail it, use certified mail with a return receipt; postal delivery introduces a lag between when you drop the form and when the VA logs it, and the stamped receipt is your proof if the date is ever disputed.

What VA Form 21-0966 Asks For

The form is short. It does not ask about your medical conditions, your service history, or any supporting evidence. It collects only what the VA needs to identify you and record your intent:⁵

Your full name, Social Security number, date of birth, and VA file number if you have one.
Your current mailing address.
The general benefit type you’re applying for: Compensation, Pension, or Survivors Pension and/or DIC.
Your signature and the date.

Two things trip people up. First, an unsigned form does not establish anything, so double-check the signature block. Second, the benefit type checkboxes protect only what you select. If you check Pension when you meant Compensation, the intent to file protects the wrong category, and by the time you notice, months of back pay may be gone. The form itself warns that the VA may not be able to establish an effective date if no benefit box is checked.

The One-Year Deadline

Once the VA receives your intent to file, you have exactly one year to submit a complete application for the benefit you selected. For disability compensation that usually means VA Form 21-526EZ with your supporting medical evidence. If the year passes without a completed application, the intent to file expires, and any application you file afterward uses its own receipt date as the new effective date.¹

There is no grace period and no extension. The protected date is simply lost.

The VA will send a reminder as the deadline approaches, but don’t rely on it. Set your own reminder for month nine or ten, and start assembling your application the same week you file the intent.⁶ Treat the year as a safety net, not a schedule.

Confirm the VA Actually Recorded It

After you submit, verify the record. Sign in to VA.gov, open the “My VA” dashboard, and look under “Track Claims” for any open intents to file, along with their dates and status.⁶ If you filed by phone or mail and don’t see it reflected within a few weeks, call 800-827-1000. A missing or misrecorded intent to file defeats the whole purpose, and catching the error early is the only way to protect your date.

When the Intent to File Doesn’t Apply

If you’re already past an initial VA decision and heading into a review, the rules shift. An intent to file does work for a Supplemental Claim (VA Form 20-0995), though you still need to file the Supplemental Claim itself within one year of the original decision to preserve your earliest possible effective date.³ It does not apply to a Higher-Level Review (VA Form 20-0996) or to Board of Veterans’ Appeals hearings. In those lanes, there is no placeholder; you must submit the review request itself within one year of the decision you’re challenging.

If a Veteran Dies With an Intent to File Pending

An active intent to file does not automatically vanish when the veteran dies. An eligible survivor, typically a spouse, child, or dependent parent, can request to step in as a substitute claimant by filing VA Form 21P-0847 within one year of the veteran’s death.⁷ If the VA grants substitution, the survivor continues the claim with the veteran’s original effective date intact. Miss the one-year window and the protected date is lost.

Getting Help From a Representative

An accredited Veterans Service Organization (VSO) representative, attorney, or claims agent can file an intent to file on your behalf once you’ve authorized them. VSO authorizations use VA Form 21-22; attorneys and claims agents use VA Form 21-22a.⁸

On fees: VSO representatives typically work at no cost, and attorneys or claims agents generally cannot charge you anything until after the VA issues an initial decision on your claim.⁹ The intent to file, evidence gathering, and initial application all fall before that point. Anyone asking for payment at those stages is a warning sign worth checking on.
