Your effective date is, as a general rule, the date VA received your claim or the date your entitlement arose, whichever is later (38 C.F.R. § 3.400). In practice that means VA usually pays from the day it got your claim (or your Intent to File), not from when your condition started. There are a few important exceptions that can reach further back: a claim filed within a year of leaving service, an increase that your records show happened up to a year before you filed, and a claim you kept alive through the review lanes after a denial.
Back pay is the gap between your effective date and the date VA decides the claim, so the effective date is often worth more than the rating fight people focus on.
The general rule
"Date of receipt" is when VA got the claim. "Date entitlement arose" is when the facts first supported the benefit, for example when you were first diagnosed. VA uses whichever is later. So if you were diagnosed in 2019 but filed in 2025, the effective date is generally 2025. If you filed in 2025 but weren't diagnosed until 2026, it is 2026.
Payment itself starts on the first day of the month after the effective date (38 C.F.R. § 3.31).
Claims filed within a year of discharge
For direct service connection, if VA receives your claim within one year after separation, the effective date is the day after you separated (or the date entitlement arose, if later). After that first year, the general rule applies (§ 3.400(b)(2)(i)).
Presumptive conditions follow a similar rule: if the claim is in within a year of leaving active duty, the effective date is the date entitlement arose (§ 3.400(b)(2)(ii)).
This is the single biggest reason to file soon after you get out, even if your records are not perfect yet.
Intent to File: holding the date for a year
An Intent to File (ITF) tells VA you plan to claim compensation. If VA gets a complete claim within one year of the ITF, it treats the claim as filed on the ITF date (38 C.F.R. § 3.155(b)). You can start one by:
- Starting and saving the online application on VA.gov
- Submitting VA Form 21-0966
- Calling VA and having it recorded
The ITF does not need to name your conditions. It does not apply to supplemental claims. If the year runs out before you file, the date is lost. See the full Intent to File guide.
Increases: the one-year look-back
For a condition that is already service-connected, the effective date of an increase is the earliest date it is factually ascertainable that the condition got worse, if your claim (or ITF) arrives within one year of that date (§ 3.400(o)(2)). Otherwise it is the date VA received the claim.
What this means for you: if a treatment note from eight months ago shows your condition at a higher level, and you file now, VA can pay the higher rate from that note's date. If the note is two years old, it can't reach that far. Medical records showing the increase count toward that date only for a condition already service-connected. See Filing for an increased rating.
After a denial: keep the claim alive
Under 38 C.F.R. § 3.2500(h), if you continuously pursue an issue by filing the next review option within one year of each decision, the effective date stays tied to your original claim. The options after an initial decision are a supplemental claim, a higher-level review, or a Board appeal.
If you file a supplemental claim more than a year after the decision, continuous pursuit is broken: the effective date can be no earlier than the date VA received the supplemental claim (§ 3.2500(h)(2)).
The practical rule: never let the one-year window after a decision lapse if you still disagree. Choosing which lane to use is a separate question; see Denied? Your appeal options.
Service records found later
If VA later gets official service department records that existed when it first decided your claim but were not in the file (for example, records the service sent late or that were declassified), VA must reconsider the claim. An award based on those records can reach back to the date of the original claim (38 C.F.R. § 3.156(c)).
When the law changes in your favor
When a new law or VA rule makes you eligible, for example a condition added to a presumptive list, the effective date can't be earlier than the date the new rule took effect. If you ask for review within a year of that date, benefits can be paid from it; if you ask later, VA can generally pay for up to one year before your request (38 C.F.R. § 3.114). See the PACT Act guide.
When the effective date itself was wrong
If you think VA used the wrong date, you can challenge it through the review lanes within a year like any other part of the decision. If the decision is older and final, the remaining route is usually a claim of clear and unmistakable error, which is a narrow and demanding standard. See CUE under 38 CFR 3.105(a).
Frequently asked questions
How far back does VA pay disability compensation?
Generally to the date VA received your claim or Intent to File, or the date your entitlement arose, whichever is later. If you filed within a year of discharge, it can go back to the day after separation. For increases, it can go back up to one year before your claim if your records show the worsening by then.
Does an Intent to File protect my effective date?
Yes. If VA receives your complete claim within one year of your Intent to File, the claim is treated as filed on the Intent to File date. It doesn't apply to supplemental claims.
Will I lose my effective date if my claim is denied?
Not if you file a supplemental claim, a higher-level review, or a Board appeal within one year of the decision, and keep doing so after each decision. A supplemental claim filed more than a year after the decision gets a new, later effective date.
When does VA payment start after the effective date?
On the first day of the month after the effective date, under 38 C.F.R. § 3.31.
Can I get back pay to when my condition started?
Usually not, unless you filed within a year of leaving service. VA pays from the later of when it received your claim and when entitlement arose, so the date you filed, or started an Intent to File, usually sets the limit.
