There's one step that takes about five minutes and can protect a full year of back pay, and most veterans skip it because they're waiting until their evidence is "ready." It's called the intent to file. It does nothing but stamp a date, but that date is the one the VA eventually pays back to. File it today, take your time building the actual claim, and you keep months you'd otherwise lose.

Watch the full breakdown, then keep reading for the timing that protects your money.

The five-minute step most veterans skip

The intent to file, or ITF, tells the VA a claim is coming and freezes your effective date while you build the case. It covers disability compensation, pension, and DIC. You don't need evidence, a doctor's letter, or any records to file it — just your identifying information. That's the whole point: it separates the date from the paperwork, so you can lock the date now and assemble the paperwork later.

There are three ways to file it, and all three set the same date, so use whichever is fastest. Online at va.gov's intent-to-file form is usually quickest. By phone, call 1-800-827-1000 (TTY: 711), Monday through Friday, 8:00 a.m. to 9:00 p.m. Eastern, and the date of the call is the date you lock. By mail, download VA Form 21-0966 and send it to the address printed inside the PDF. However you do it, from that date your effective date is protected for a year.

How the effective date actually works

The effective date is the day the VA starts counting your back pay, and it's the number that decides how much you collect. The date the VA finally grants the claim doesn't matter to the money. If the VA takes eighteen months to decide and then grants it, you get all eighteen months in one retroactive check, counted from the effective date.

The rule itself is short. Your effective date is the date the VA received your claim or your ITF, or the date the condition actually became disabling, whichever of those is later. Because the ITF counts as a date of receipt, filing it early is what pulls the whole thing back in your favor.

Day 0
Intent to file
File the ITF. It only stamps a date, but that date is what the VA pays back to.
1 year
The full claim
You have up to a year to submit VA Form 21-526EZ. Treat the eleven-month mark as the real deadline.
Back pay
Paid to Day 0
Whenever the VA grants it, the money counts from the intent-to-file date, not the decision date.
The intent to file stamps Day 0 — back pay is paid all the way back to it

Here's how it plays out. Say you file an ITF on January 1, your evidence takes nine months to assemble, you submit the 21-526EZ on September 30, and the VA grants it in December. Your effective date is still January 1. That's nine months of back pay you earned with one five-minute step back in January.

There's one extra break for the recently separated. File within a year of leaving active duty and the effective date can reach all the way back to the day after you separated, even if the claim itself lands months later. Anyone still in their first year out should file right away to catch it.

File now or wait? The math favors now

The temptation is to hold off until everything is perfect — records pulled, nexus letter in hand, every condition listed. But nothing about your effective date moves while you wait. The ITF was built precisely so you don't have to choose between filing early and filing well. You get both: the date now, the evidence on your own schedule.

Option 1 · File the ITF today
38 CFR § 3.155(b)
Lock the date, build later
  • Stamps your effective date the day you file
  • Buys up to a year to gather records and evidence
  • Back pay counts from this date, however long the claim takes
Option 2 · Wait for "ready"
no date protected
The clock doesn't start until you file
  • Your effective date doesn't move while you wait
  • Every month waiting is a month of back pay you can lose
  • Nothing reminds you — the window just closes on its own
Same claim, same evidence — only the timing changes what you collect
Use the year you bought Once the ITF is in, pull your DD-214, write out every condition you're claiming (the minor and secondary ones included), note where you've been treated so the VA can request records, and line up a nexus letter for anything that isn't presumptive. The date is protected while you do all of it.

What veterans get wrong about timing

Myth: I should wait until my evidence is ready to file anything.

The ITF exists precisely so you don't have to wait. Get the date on the record, then build. Waiting protects nothing.

Myth: back pay runs from the day the VA decides.

It runs from the effective date, through the entire wait — which is exactly why protecting that date early matters even if the claim drags on or goes to appeal.

Myth: the intent to file needs evidence or a doctor's letter.

It needs only your identifying information. No records, no nexus, no diagnosis to file the ITF itself. That's what makes it a five-minute step.

Myth: I'll just file the whole claim online soon, so the ITF is pointless.

Soon has a way of slipping. The ITF is five minutes of insurance on your date, and the one-year window dies quietly if you let it.

What claim are you timing? The four lanes

While the clock runs, it helps to know which type of claim you're actually building, because each lane asks for different evidence and some are far faster to prove than others. Every VA disability claim travels one of four lanes. Picking the right one before you file saves you from gathering proof the law never required.

Direct
38 CFR § 3.303(a)
Service caused it, or it started in service
  • Current diagnosis
  • An in-service event or exposure
  • A medical nexus linking the two
Secondary
38 CFR § 3.310(a)
A rated condition caused or worsened it
  • An existing service-connected condition as the anchor
  • A nexus tying that anchor to the new condition
  • No in-service event needed for the secondary condition
Presumptive
38 CFR §§ 3.307 / 3.309
The law does the linking for you
  • Qualifying service in the right place at the right time
  • A current diagnosis of a listed condition
  • No nexus letter required — the fastest lane where it fits
Aggravation
38 CFR § 3.306(a)–(b)
Service worsened a condition you had before
  • A pre-service baseline for the condition
  • Records showing it got worse during service
  • Compensation covers the increase service caused
Four ways to prove service connection — pick the easiest winning lane before you file

Lane selection matters because it changes what you must prove. A veteran with a service-connected knee and knee-caused sleep apnea who files a direct claim for the sleep apnea may struggle — there may be no in-service event for the sleep apnea itself. A secondary claim connecting it to the rated knee can succeed where the direct lane fails. The evidence doesn't change; the lane does. And a veteran with qualifying service and a condition listed under § 3.309 doesn't legally need a nexus letter at all, so check the presumptive lists before you pay for one.

How to file, briefly

The full claim is VA Form 21-526EZ. You can file it yourself online at va.gov's disability-claim page, or have an accredited representative do it. Filing through a VSO is free and the better move for most people: they help you put the 21-526EZ together and look it over for gaps before the VA ever sees it, at no charge. You appoint one with VA Form 21-22 through va.gov's accredited-representative page.

The hard part isn't the form, it's the deadline. The completed 21-526EZ has to reach the VA within one year of the ITF. If it doesn't, the ITF dies, and while you can file a new one, the months in between are no longer protected. Don't run it to the wire — treat the eleven-month mark as your real deadline.

Your next moves

  1. File the intent to file today — online, by phone at 1-800-827-1000, or by mail on VA Form 21-0966. Save the confirmation and the date.
  2. Put the eleven-month mark from that date on your calendar as the real deadline for the full claim.
  3. Pull the claim together: DD-214, your list of conditions, where you've been treated, and a nexus letter for anything that isn't presumptive.
  4. Match each condition to its lane — direct, secondary, presumptive, or aggravation — so you gather the right evidence and not the wrong.
  5. File VA Form 21-526EZ, or have a VSO file it for free, before the year is up. If you got out within the last year, file now to reach back to the day after you separated.
