The effective date determines when your VA disability compensation begins and directly affects how much back pay you receive. Understanding effective date rules can mean the difference between months and years of retroactive compensation.
The general rule is that the effective date is the later of two dates: the date the claim was received by the VA, or the date entitlement arose (the date the medical evidence shows the disability existed). In practice, for most initial claims, the effective date is the date the VA received the claim.
The Intent to File (VA Form 21-0966) is one of the most important tools for protecting your effective date. An Intent to File gives you one year to submit the full claim while preserving the earlier filing date as your effective date. This means you can lock in today's date, then take up to a year to gather medical evidence, obtain nexus opinions, and prepare your claim. If the claim is ultimately granted, compensation is paid back to the Intent to File date.
For claims filed within one year of separation from active duty, the effective date can be the day after separation, regardless of when the claim is filed during that first year. This makes filing before or immediately after discharge extremely important.
For increased rating claims, the effective date is the date the claim is received, or up to one year earlier if the evidence shows the disability worsened within the one-year period before the claim was filed.
For reopened claims (Supplemental Claims filed more than one year after a final decision), the effective date is the date of the new claim, not the original claim. However, if a Supplemental Claim is filed within one year of the prior decision, the effective date can relate back to the original claim.
Clear and unmistakable error (CUE) claims can result in an effective date going back to the original erroneous decision, potentially providing years of back pay.
