How to file an Intent to File (VA Form 21-0966) — lock in your effective date BEFORE filing your claim
Filing an Intent to File (ITF) under 38 CFR § 3.155(b) creates a 1-year window during which any claim you file will use your ITF date as the effective date — preserving back pay you would otherwise lose. ITF is the SINGLE MOST IMPORTANT procedural step most veterans skip: a 5-minute call to 1-800-827-1000 (or VA Form 21-0966) can preserve $10K-$50K+ in retroactive benefits if your eventual claim takes 6-12 months to gather evidence. Effective date determines when your monthly benefits BEGIN, and VA pays back to that date once approved. WITHOUT an ITF: effective date = the date you finally submit your formal claim. WITH an ITF: effective date = the date you submitted the ITF (up to 1 year before your formal claim). 5 steps: understand the back-pay math, choose your filing method, submit the ITF, gather evidence within 1 year, file the formal claim citing the ITF.
What you'll need
- VA Form 21-0966 (Intent to File a Claim for Compensation and/or Pension, or Survivors Pension and/or DIC) — va.gov/find-forms/about-form-21-0966
- OR call VA at 1-800-827-1000 to file an oral ITF (telephonic — they document it on your record)
- OR file electronically via VA.gov "Start your application" workflow (the system creates an ITF the moment you click Start, even if you save and return later)
- CVSO/VSO assistance — most file ITF the same day you contact them
- Calendar reminder set for 11 months from ITF date (formal claim deadline)
Step-by-step
Step 1: Understand the back-pay math (why ITF matters more than you think)
Effective date is set by 38 CFR § 3.400 — generally the LATER of the date entitlement arose OR the date VA received the claim. Without an ITF, every month you spend gathering evidence is a month of back pay you lose forever. EXAMPLE: Veteran develops sleep apnea symptoms in January. Spends 8 months getting a sleep study, scheduling a nexus exam, gathering buddy statements. Files claim in September. Award rated 50% ($1,102/mo 2024). VA approves in March of the following year. Without ITF: effective date = September (claim filing date). VA pays from September forward — 6 months of back pay = $6,612. With ITF filed in January: effective date = January. VA pays from January forward — 14 months of back pay = $15,428. Difference: $8,816 in retroactive comp the veteran kept by spending 5 minutes filing an ITF. For higher ratings (70-100%) the difference can exceed $30K. For TDIU or SMC claims, $50K+ is common. ITF cost = $0. Time = 5 minutes.
Step 2: Choose your filing method (3 paths, all equally valid)
(A) WRITTEN: Download VA Form 21-0966 (1 page), fill in your name + SSN/file number + benefit type (Compensation / Pension / DIC / Survivors Pension), sign + date, mail to VA Evidence Intake Center, PO Box 4444, Janesville WI 53547-4444 (or fax 844-531-7818). Effective date = date VA receives form. (B) TELEPHONIC: Call VA at 1-800-827-1000, tell the rep you want to file an Intent to File for [compensation / pension / DIC]. They document it in your VBMS record with that day's date. Get the rep's name + reference number. Effective date = date of call. (C) ELECTRONIC: Go to VA.gov, sign in (DS Logon, ID.me, or Login.gov), click "File a Disability Claim" or "File for Pension." The moment you click START on the disability application, VBMS auto-creates an ITF dated that day — EVEN IF YOU SAVE AND DON'T SUBMIT. You then have 1 year to complete and submit the formal claim. This is the easiest path for tech-comfortable veterans.
Step 3: Submit the ITF — what to expect
WRITTEN: VA mails confirmation letter within 30-60 days showing ITF date. KEEP THIS LETTER. TELEPHONIC: Get a reference number on the call. Within 30 days, VA mails confirmation. ELECTRONIC: VA.gov shows "Your Intent to File expires on [date 1 year from now]" on your dashboard immediately. Email confirmation usually arrives within 24 hours. ALL paths: log into VA.gov, click "Track Your Claims" → "Your Intent to File" to verify it shows up. ITFs are tracked in VBMS the same day. If your written ITF doesn't show up after 60 days, call 1-800-827-1000 with your fax/mail receipt to confirm. The 1-year clock starts the day VA receives your ITF — not the day you mail it. For mailed ITFs, file early and KEEP YOUR MAIL RECEIPT.
Step 4: Gather evidence within the 1-year window
You now have 365 days from the ITF date to file your formal claim (VA Form 21-526EZ for compensation, 21P-527EZ for pension, 21P-534EZ for DIC). Use this time to: (1) request your VA medical records via va.gov/health-care/get-medical-records (free); (2) request private treatment records from civilian doctors (often takes 30-60 days); (3) schedule a Disability Benefits Questionnaire (DBQ) with a private doctor for nexus opinion ($300-$1,500 — but this evidence dramatically improves grant rates); (4) gather buddy statements from service members who witnessed events (VA Form 21-10210); (5) request your SMR (Service Medical Records) and OMPF (Official Military Personnel File) from National Personnel Records Center via dpris.dmdc.osd.mil (free); (6) for PACT Act presumptive conditions, gather deployment records showing toxic exposure. CRITICAL: any evidence dated AFTER your ITF date can still support effective date back to the ITF — the ITF preserves the date, evidence development happens after.
Step 5: File the formal claim CITING the ITF
When you file VA Form 21-526EZ (or 21P-527EZ, etc.), in the "Remarks" or "Statement in Support of Claim" section, write: "This claim is filed pursuant to Intent to File submitted on [DATE] under VA Form 21-0966 / [reference number if telephonic / electronic save]." This is BELT AND SUSPENDERS — VBMS should auto-link the ITF to your claim, but explicitly citing it ensures the rater applies the earlier effective date. If your final claim date is within 1 year of your ITF date, your effective date will be the ITF date (subject to date of medical entitlement). VA Form 21-526EZ section "Effective Date" can also reference: "Request effective date of [ITF date] pursuant to 38 CFR § 3.155(b)." If VA assigns a wrong effective date in the decision, file a Higher-Level Review (NOT Supplemental Claim) within 1 year of decision date and cite the ITF — effective date errors are commonly fixed at HLR. SECONDARY USE: ITFs also work for survivors. If a veteran dies, surviving spouse should file ITF for DIC the SAME WEEK to preserve effective date back to month after death.
Critical tips
- ITF is FREE. Filing one costs nothing. The downside risk is zero. The upside is potentially $50K+ in preserved back pay. There is no reason NOT to file an ITF as soon as you suspect you might have a claim.
- ITFs do NOT obligate you to file a claim. If you change your mind, you simply let the 1-year window expire. No penalty.
- You can file MULTIPLE ITFs over time — one for compensation, one for pension, one for DIC. Each preserves its own benefit type effective date.
- For DIC: surviving spouse should file ITF the same week as veteran's death. 38 CFR § 3.400(c) allows DIC effective date back to the first day of the month after death IF claim filed within 1 year of death — ITF preserves this even if claim takes 11 months.
- For TDIU claims: file an ITF the moment you stop working OR the moment your earnings drop below substantially gainful employment ($16,553/year 2024). Effective date is critical for TDIU back pay.
- For PACT Act presumptive conditions: file ITF the day you become aware of any qualifying condition. Even if you wait 11 months to file the formal claim, you preserve back pay to the ITF date.
- CVSO/VFW/Legion/DAV will file an ITF for you for free, same day, in person — usually faster than the website.
- Save the ITF confirmation in 3 places: email, paper file, and a photo on your phone. Effective date is one of the most-litigated issues at the Board of Veterans' Appeals — proof of filing matters.
- If you ALREADY filed a claim without first filing an ITF, you can't go back. But for ANY future claim — even an increase rating, a secondary condition, or a CUE motion — file an ITF first.
- For widow's tax repeal claims (SBP-DIC): even retired survivors can file an ITF to claim retroactive DIC if a veteran spouse died of service-connected causes years ago. 38 CFR § 3.114 allows up to 1 year of retro on liberalized law claims.
