Intent to File (Form 21-0966)

Key concept. An Intent to File (ITF) is the single cheapest, highest-leverage move in the entire VA disability process. It costs nothing, takes ten minutes, and can be worth tens of thousands of dollars in retroactive back pay.

What it does

Filing Form 21-0966 (Intent to File a Claim) tells VA you intend to file a disability claim within the next 12 months. As soon as you submit it, VA establishes a placeholder effective date based on the ITF date. If you then submit your formal claim (Form 21-526EZ) within 365 days, any benefits awarded are backdated to the ITF date — not the date you filed the formal claim.

Worked example

You decide on January 1, 2026 that you’ll eventually file a claim for PTSD, tinnitus, and a knee condition. You’re not ready — you don’t have your STRs yet, you haven’t lined up a nexus letter, you haven’t written your statements. You file Form 21-0966 that day.

Eleven months later, on December 1, 2026, you submit your fully-developed 21-526EZ. VA processes the claim and grants 70% PTSD, 10% tinnitus, 20% knee — combined 80%. Back pay accrues from January 1, 2026, not December 1. That’s 11 months of back pay at the 80% rate (roughly $2,100/month) = around $23,100 in retroactive payment, just because you filed the ITF first.

How to file

• Online at VA.gov (recommended — instant timestamp, can’t be lost)
• By phone at 1-800-827-1000 (VA will generate the ITF for you)
• By mail or in person using Form 21-0966

Strategy

If you are currently active duty and within 12 months of separation, file an ITF the day you have your separation date. You then have a year of post-separation runway to gather evidence and file the formal claim, and your effective date is locked. Combined with the 1-year-post-discharge rule, this can be enormously valuable.
