VA deadlines can look simple on paper and still create major problems in real life. A decision letter arrives, the clock starts, and suddenly the questions pile up: Is the deadline one year or 120 days? When can new evidence still be added? What happens if the wrong review lane gets picked? And what happens to back pay if too much time passes?
This is where a lot of veterans get tripped up. In general terms, VA timing rules are not just paperwork rules. They often affect whether a claim stays alive, whether an earlier effective date remains protected, and whether a veteran keeps access to certain review options.
In this post you’ll learn how the VA’s one-year review windows work, how evidence timing changes depending on the lane you choose, how Court deadlines differ from VA deadlines, and what steps often help protect appeal rights. If you want a broader foundation first, it may help to start with this overview of the VA claims and appeals system.

A missed deadline does not always end a benefits case forever. But it often changes the posture of the case in ways that matter.
According to the VA, for most VA benefits, a claimant has 1 year from the date on the decision letter to request a Higher-Level Review or a Board Appeal. A Supplemental Claim can be filed later, but filing within that one-year period may help preserve the effective date. The VA explains this directly in its decision review FAQ and Board appeal guidance, which are some of the clearest official sources on the point: VA decision review FAQs and Board appeal guidance.
That timing rule matters because VA law includes the concept often called continuous pursuit. In plain language, when a veteran keeps moving a denied issue forward through the available review options within the allowed time, the earlier claim date may remain protected for effective-date purposes. The Board of Veterans’ Appeals has described this as a feature of the modern appeals system that helps preserve the earliest possible effective date when a claimant keeps the matter moving on time: Board explanation of AMA workload and continuous pursuit.
If you want a simpler overview focused just on the core timing rules, this plain-language guide to VA timing rules may help as a companion read.
The phrase “one-year deadline” gets used a lot, but it helps to be precise.
After an initial claim decision, a veteran will often have three modern review paths available:
The VA states that, for most benefits, the deadline to request a Higher-Level Review or Board Appeal is 1 year from the date on the decision letter. The VA also states that a Supplemental Claim may be filed at any time, but filing it within 1 year is what helps preserve the effective date: VA decision review FAQs.
That same one-year structure often applies again after a Supplemental Claim decision or a Higher-Level Review decision. The VA’s Board appeal page explains that a Board Appeal may be requested within 1 year of the decision on an initial claim, Supplemental Claim, or Higher-Level Review: Board appeal page. The VA’s general decision-review materials also explain that after a Supplemental Claim decision, a claimant may request another Supplemental Claim, a Higher-Level Review, or a Board Appeal, depending on the procedural posture: Choosing a decision review option.
In general terms, that means the one-year window is not a one-time event. It often reappears after each new review decision, and the exact next-step options depend on where the case currently sits.
