The effective date is the date from which the VA pays compensation on a granted claim. It determines how much back pay (retroactive benefits) you receive. The general rule is the later of: (1) the date the VA receives your claim, or (2) the date entitlement arose. But there are significant exceptions that can reach back years — or even decades.
Missing a deadline or failing to file an Intent to File can cost thousands of dollars in back pay. Understanding these rules before you file is one of the highest-value things a Veteran can do.
The General Rule
Date of Claim or Date Entitlement Arose — Whichever Is Later
For most original claims, the effective date is the date the VA receives the completed claim form — or the date service connection is established (entitlement arose), whichever comes later. In practice, “entitlement arose” usually means the date of the diagnosis that creates the current disability. If you were diagnosed before filing, the date of claim controls.
Rules That Can Move the Date Earlier
One-Year Lookback — Filing Within a Year of Discharge
If you file a claim within one year of your separation from active duty, the effective date is the day after your date of separation — not the date you filed. This is one of the most valuable rules in Veterans law and is commonly missed.
Intent to File (ITF) — Locking In Your Date for One Year
Filing an Intent to File (ITF) on VA Form 21-0966 establishes a placeholder date. Once you submit an ITF, you have one year to submit your complete claim. If granted, your effective date is the date the ITF was received — not the date you submitted the full claim. An ITF costs nothing and takes minutes.
Increased Rating Claims — Date of Worsening
For a claim to increase an existing rating, the effective date is the date of claim — or the date the condition first showed evidence of worsening at the level that warrants a higher rating, whichever is earlier, but only if the medical evidence clearly shows the increase existed before the claim date. Treatment records, hospitalization records, or other evidence showing the worsening predated your claim can push the effective date back.
Secondary Service Connection — Date of Claim
For secondary conditions (conditions caused or aggravated by a primary SC condition), the effective date is generally the date the secondary claim is filed — not the date the primary condition was established. This means if you develop a secondary condition years after your primary rating, filing promptly is critical. Every month you wait is a month of back pay you cannot recover.
Newly Discovered Service Records — Back to Original Claim
If a claim was denied and new service records are later associated with the file — records that were not previously available — the VA must reconsider the original claim from the original date. This most commonly applies when service treatment records, personnel files, or unit records are later found in the National Archives or NPRC.
Clear and Unmistakable Error (CUE) — Back to the Original Decision
If a prior VA decision contained a Clear and Unmistakable Error (CUE) — a specific type of undebatable legal or factual error — a successful CUE claim reaches back to the date of the original erroneous decision. CUE is a narrow and high legal standard: the outcome must be "manifestly different" from what it should have been under the correct application of law and facts. CUE is not the same as a disagreement with how evidence was weighed.
TDIU Effective Dates
For Total Disability based on Individual Unemployability (TDIU), the effective date is generally the date the VA Form 21-8940 is received — or the date of a claim that reasonably raised TDIU entitlement, whichever is earlier.
Importantly, courts have held that a claim for an increased rating that results in a rating at the TDIU threshold can implicitly raise the TDIU question — meaning the VA must consider TDIU even if you did not explicitly file 21-8940. If the VA failed to consider TDIU when your ratings reached the threshold, the effective date of a successful TDIU claim can be tied to the original increased-rating claim date, not a later TDIU filing date.
Quick Reference
| Scenario | Effective Date |
|---|---|
| Original claim, standard | Date VA receives claim |
| File within 1 year of discharge | Day after date of separation |
| Intent to File (ITF) filed first | Date ITF received (up to 1 year later) |
| Increased rating claim | Date of claim, or earlier date of worsening supported by evidence |
| Secondary condition claim | Date secondary claim is filed |
| Newly discovered service records (§3.156(c)) | Date of original denied claim |
| Clear and Unmistakable Error (CUE) | Date of original erroneous decision |
| TDIU — explicit 21-8940 filed | Date 21-8940 received |
| TDIU — implicitly raised by increased rating claim | Date of the underlying increased rating claim |
