The VA one-year lookback rule lets the agency set your disability compensation effective date up to 12 months before the day you actually filed, which means more retroactive pay when it applies. It shows up in four distinct situations: filing shortly after discharge, requesting an increase for a condition that worsened before you filed, claiming a newly presumptive condition after a change in law, and filing survivor benefits after a veteran’s death. Each has its own timing rule and its own evidence requirements. Miss the year in any of them and your effective date defaults to the date the VA receives your claim, with all the months in between lost.
The default rule is that the effective date for a new or supplemental claim cannot be earlier than the date the VA receives your application.1Office of the Law Revision Counsel. 38 USC 5110 – Effective Dates of Awards Every lookback below is a carveout from that default.
Filing Within One Year of Discharge
File an original disability claim within one year of leaving active duty and the VA sets your effective date as the day after your discharge, not the date it received your paperwork.2Office of the Law Revision Counsel. 38 USC 5110 – Effective Dates of Awards The transition from military pay to VA compensation runs with no gap.
The rule applies to original claims that connect a current disability to something that happened during service. Wait even one day past the one-year mark and the effective date reverts to whenever the VA receives your claim. At a 70% or higher rating, a single day past the deadline can cost thousands in back pay. If you’re still gathering medical records or adjusting to civilian life, file an Intent to File inside that first year to preserve the date while you finish preparing the full application.
What Severance Pay Does to Your First Checks
If you received disability severance pay at separation, the VA has to recoup it from your compensation before your monthly payments start reaching your account.3eCFR. 38 CFR 3.700 – General For separations after September 30, 1996, the recoupment amount is the severance minus the federal income tax withheld. Monthly compensation is held back at the rate payable for the disability that generated the severance until the balance is recovered.
Veterans who separated under a medical discharge on or after January 28, 2008 are exempt from recoupment if the disability was incurred in a combat zone or during combat-related operations as designated by the Department of Defense.3eCFR. 38 CFR 3.700 – General Outside that exception, plan for the possibility that your first several months of compensation go toward paying back the severance rather than hitting your bank account.
The One-Year Lookback for Rating Increases
This is the version of the lookback that catches most veterans off guard. If you’re already service-connected and your condition gets worse, you can request a higher rating. Normally the effective date for the increase is the date the VA receives your claim. But if medical evidence shows the worsening happened within the 12 months before you filed, the VA can backdate the higher rating to the date it became factually ascertainable that the increase occurred.4eCFR. 38 CFR 3.400 – General – Section: (o) Increases
The evidence has to do two things at once: show your disability reached the criteria for the higher rating, and pin down the specific date it did so. A doctor’s note saying “the veteran’s knee has gotten worse over the past two years” doesn’t pin down a date. A treatment record from eight months ago documenting limited range of motion that meets the next rating level does. The more precisely your records mark when symptoms crossed the threshold, the stronger your case for the earliest possible effective date.
This lookback also functions as a deadline. If the worsening is already documented in your medical records, the clock starts on the date of those records. File your claim or an Intent to File within one year of that date, or the effective date reverts to the day the VA receives your claim.4eCFR. 38 CFR 3.400 – General – Section: (o) Increases
Temporary Total Ratings for Hospitalization
A separate mechanism applies if you’re hospitalized for more than 21 consecutive days to treat a service-connected condition. The VA can assign a temporary 100% rating effective from the date of admission.5eCFR. 38 CFR 3.401 – Veterans The 21-day requirement is strict. Admission records from the treating facility are usually enough to establish the timeline.
New Laws and Presumptive Conditions
When Congress adds conditions to the VA’s presumptive list, a separate one-year lookback opens up. File within one year of the law’s effective date and the VA can set your effective date as the date the law took effect rather than the date you filed.6Office of the Law Revision Counsel. 38 USC 5110 – Effective Dates of Awards The implementing regulation sets tiered rules depending on when the claim is filed or reviewed relative to that effective date.7eCFR. 38 CFR 3.114 – Change of Law or Department of Veterans Affairs Issue
The PACT Act, signed August 10, 2022, is the most recent large example. It added dozens of respiratory and other toxic-exposure conditions to the presumptive list with phased effective dates, so the one-year window started on different days for different conditions. Where the window has already closed, the standard rule applies and your benefits start from the date the VA receives your claim.
Any time Congress adds new presumptive conditions or the VA issues an administrative determination expanding eligibility, the one-year window reopens for those specific conditions. Filing promptly when a change lands is the difference between months of additional back pay and no retroactive benefit.
Survivor Benefits
The one-year lookback also covers Dependency and Indemnity Compensation for surviving spouses and dependents. File a DIC claim within one year of the veteran’s death and the effective date is the first day of the month in which the death occurred.6Office of the Law Revision Counsel. 38 USC 5110 – Effective Dates of Awards This applies whether the death was service-connected or not, as long as the claim reaches the VA inside that one-year window.8eCFR. 38 CFR 3.400 – General
File after the year is up and the effective date defaults to the date the VA receives the application. Every month between the death and the filing is lost. Grieving families rarely prioritize paperwork, and even an Intent to File during the first year preserves the retroactive date while the family gathers full documentation.
Evidence the VA Needs
What you need to prove depends on which version of the lookback applies:
- For claims filed within a year of discharge, your DD-214 or equivalent separation document establishes the date. When you file, the VA requests this record on your behalf.9U.S. Department of Veterans Affairs. Request Your Military Service Records
- For rating increases, you need treatment records, doctor’s notes, imaging results, or hospitalization records that show when symptoms reached the level of the higher rating. Vague references to gradual worsening carry far less weight than specific clinical findings on a specific date.
- For a liberalizing law, you need proof you meet the criteria for the newly presumptive condition together with proof that you filed within one year of the law’s effective date.
- For survivor claims, the veteran’s death certificate and evidence of the cause of death or the veteran’s service-connected disabilities at the time of death.
Across every scenario, the VA dates increases to the earliest point when the evidence shows you met the criteria, but only if your claim was received within one year of that date.10U.S. Department of Veterans Affairs. Disability Compensation Effective Dates Being precise with dates in your application and pointing the claims processor to the specific records that support them makes a measurable difference.
Protecting Your Date With an Intent to File
An Intent to File is the single most important tool for preserving an earlier effective date when your full claim isn’t ready. Filing one locks in a potential effective date for up to a year, giving you time to gather records, schedule exams, and prepare the application.11U.S. Department of Veterans Affairs. Your Intent to File a VA Claim
You can submit one three ways: online through VA.gov (starting a disability claim application creates one automatically), by calling the VA’s national helpline at 1-800-827-1000, or by mailing or hand-delivering VA Form 21-0966 to your regional office.12Department of Veterans Affairs. VA Form 21-0966 The date the VA receives it becomes your potential effective date if the eventual claim is granted.
The catch: file a complete claim within one year of the Intent to File or it expires and the VA takes no further action.13eCFR. 38 CFR 3.155 – How to File a Claim You won’t get benefits based on an expired Intent to File, and you’d have to start over with a fresh filing. Mark the expiration date on your calendar the day you submit it.
If the Year Has Already Passed
Two situations sit outside the one-year lookback but can still produce an earlier effective date.
The first is when relevant service department records surface later. If the VA receives or discovers service records that weren’t in your claims file at the time of the original decision, it must reconsider the claim. An award based on those records dates back to the later of when entitlement arose or when the VA received the original claim. Effective dates under this rule can reach back years or decades. Qualifying records include service records related to a claimed injury or event, records forwarded by the Department of Defense after the VA’s original request, and declassified records that weren’t available when the first decision was made. The exception doesn’t apply if the records didn’t exist when the VA decided the claim, or if you failed to give the VA enough information to locate them.14eCFR. 38 CFR 3.156 – New Evidence A retroactive rating still needs medical evidence supporting the assigned evaluation over the earlier period.
The second is Clear and Unmistakable Error. If a past VA decision assigned the wrong effective date because of an obvious legal or factual mistake, you can request a revision. A successful CUE claim rewrites the original decision as if it had been decided correctly the first time. The standard is deliberately high. You have to show that the correct facts known at the time weren’t before the VA, or that the VA misapplied the law as it existed then. The error has to be undebatable, not a judgment call about how evidence was weighed, and it has to have changed the outcome.15eCFR. 38 CFR 3.105 – Revision of Decisions Broad arguments like “the VA failed to follow regulations” will be denied. The VA has no duty to help develop a CUE claim, so the burden falls on you.
Disagreeing With the Effective Date the VA Assigned
If the VA grants your claim but gives you an effective date you believe is wrong, three options are available under the current decision review system.16U.S. Department of Veterans Affairs. Choosing a Decision Review Option
A Supplemental Claim, filed on VA Form 20-0995, is for new and relevant evidence that wasn’t part of the original decision. File within one year of the decision notification letter to preserve eligibility for the earliest possible effective date.17Department of Veterans Affairs. Decision Review Request: Supplemental Claim (VA Form 20-0995) New evidence might be medical records you didn’t previously submit, a doctor’s opinion tying your worsening to a specific earlier date, or service records that weren’t in the file.
A Higher-Level Review asks a more senior reviewer to reexamine the decision based on the evidence already on file. No new evidence can be submitted.18U.S. Department of Veterans Affairs. Higher-Level Reviews You can request an optional informal conference, a phone call where you or your representative can point out where you think the VA got it wrong. This works best when the medical records already support an earlier effective date and the original decision overlooked or misread them.
A Board of Veterans’ Appeals review puts your case before a Veterans Law Judge. The Board has three dockets: direct review (no new evidence, no hearing), evidence submission (new evidence allowed), and hearing (you testify before the judge). Board appeals take longer than the other two options but give you an independent review outside the regional office that made the original decision.
