The question is simple. When should you file a VA disability claim? File as soon as you can name the conditions and lock a date. Waiting until the packet looks perfect is how veterans lose the day-after-discharge start date, or months of pay after an Intent to File expires.

There is no statute of limitations that closes the door on a first disability claim years after you leave service. VA's when-to-file page says there is no time limit on a postservice claim. That is not a reason to wait. The date VA first has your claim, or your notice that you intend to file, is often the date monthly pay starts if the claim is later granted. That date is the effective date. This post explains the one-year window after discharge, Benefits Delivery at Discharge for separating service members, and what “file later” actually costs. It is based on the official VA pages and 38 U.S.C. § 5110 opened on August 18, 2026. It does not promise a grant, a rating, or a dollar amount.

The official rule on when pay can start

Federal law sets the start date. 38 U.S.C. § 5110(a) says the effective date of an award based on an initial claim or a supplemental claim is fixed in accordance with the facts found, but shall not be earlier than the date of receipt of the application. In plain words: VA generally does not pay you for time before it had a claim in hand.

There is a first-year exception that matters more than any other date on this page. 38 U.S.C. § 5110(b)(1) says the effective date of an award of disability compensation shall be the day following the date of discharge or release if the application is received within one year from that discharge or release. File within that year, and a later grant can pay from the day after you left. File on day 366, and the same grant usually pays from the date VA received the claim, not from the day you became a veteran.

That is not a small difference. It is every month between discharge and the late filing date. Those months do not come back because the medical facts were always the same.

Two other date rules sit next to that statute. If you start a disability claim online on VA.gov and finish it within 365 days, VA treats the day you started as your date of claim. You do not need a separate Intent to File form for that online start. If you plan to file on paper, VA Form 21-0966, Intent to File a Claim for Compensation and/or Pension, or Survivors Pension and/or DIC, can lock a date for one year. VA's own example, last updated August 17, 2026: you submit an Intent to File on April 2, you file the claim on July 15, and if benefits are awarded the effective date is April 2, not July 15.

You can have only one active Intent to File at a time. When you file the completed claim, that Intent to File is used up. You can still add conditions to the claim you just filed. A second benefit type, such as pension, needs its own Intent to File.

If you are still on active duty: BDD is a window, not a slogan

VA's pre-discharge page, last updated June 18, 2026, describes Benefits Delivery at Discharge as the claim process for service members who file between 180 and 90 days before they leave the military. That is the window VA published. This post does not invent a different BDD deadline.

You may be eligible for BDD if all of these are true, in VA's words: you are a service member on full-time active duty, including National Guard, Reserve, or Coast Guard; you have a known separation date with 180 to 90 days left on active duty; and you are available to go to VA exams within 45 days of the date you submitted the claim. When you file, submit a completed Separation Health Assessment — Part A Self-Assessment. If you file the BDD claim online, VA says it will get your service treatment records for you. If you do not file online, you need to provide a copy of those records with the claim.

VA's Benefits Delivery at Discharge program page states the same 180-to-90-day filing window. It also states BDD's goal: deliver a decision within 30 days after separation. That is a program goal. It is not a deadline for your file and not a promise that your decision will arrive in 30 days.

You cannot use BDD if the claim needs special handling, even if you still have more than 90 days left. VA lists those situations: you need case management for a serious injury or illness; you are terminally ill; you are waiting for discharge while being treated at a VA hospital or military treatment facility; you are waiting for a Character of Discharge determination; or you cannot go to a VA exam during the 45-day period after you submit the claim.

You can add medical conditions to a BDD claim until day 90 before your expected discharge. VA will include those conditions with the original claim. If you add a condition when you have less than 90 days left, VA may not process those added conditions until after discharge.

Less than 90 days left: you can still file before you leave

If you have fewer than 90 days left on active duty, you cannot file through BDD. VA says that on the when-to-file page and on the pre-discharge page. You can still file a pre-discharge disability claim before you separate. VA will process it after separation as a fully developed claim or a standard claim.

That filing still matters for the date. A claim VA receives before discharge is a claim in hand. Waiting until you are home, unpacked, and “ready” is how the one-year clock in § 5110(b)(1) starts running without a claim on file.

If you are wounded, injured, or ill and cannot perform your duties, your doctor may refer you to the Integrated Disability Evaluation System. IDES is a separate path. If you are found medically unfit, IDES gives a proposed VA disability rating before you leave. That is not BDD. Do not treat them as the same program.

After discharge: no time limit, but the date still moves

VA calls the first claim you file for a disability your original claim. You can also file after discharge for a disability that appears later. That is a postservice claim. There is no time limit on filing it. VA's when-to-file page, last updated May 3, 2024, says the process may become more complex the longer you wait. Records scatter. Witnesses move. Clinic notes from the year you got out are harder to find in year ten.

Complexity is not the only cost. Under § 5110(a), a claim filed years later generally cannot pay from the day after discharge. The start date is the date of receipt, unless another rule in that section applies. An Intent to File or an online start can protect a date going forward. Neither one reaches back to a discharge that was already more than a year ago.

Separate from the effective-date rule is a medical presumption that also uses a one-year clock. If certain chronic conditions listed in 38 C.F.R. § 3.309(a) appear to a compensable degree within one year after discharge, VA may presume service connection. VA's page on disabilities that appear within one year after discharge names examples: hypertension, arthritis, diabetes, or peptic ulcers, if the condition is at least 10% disabling, is on that list, and the discharge is not dishonorable. That presumption is about whether the condition is connected to service. It is not the same as the § 5110(b)(1) rule about when pay starts. You can lose the day-after-discharge pay date and still later prove the condition. You can also file in time for the pay date and still need a diagnosis that meets the schedule.

A few illnesses have longer presumptive windows on that same VA page. Hansen's disease and tuberculosis can appear within three years after discharge. Multiple sclerosis can appear within seven years. ALS can appear any time after discharge. Those are official exceptions on the page opened August 18, 2026. They are not a reason to sit on a claim you already know you have.

The practical mistake that costs back pay

The common error is treating “when to file” as “when the file looks finished.” Veterans wait for a private MRI, a buddy they have not reached, or a good week to sit down with the form. Meanwhile the one-year discharge window closes, or an Intent to File expires, or an online application sits past 365 days and the start date dies.

VA does not require you to attach evidence. That is technically true. It is also how claims sit in evidence gathering. The better sequence is lock the date, then send the records you have. Name every condition you want decided. You can add conditions while a claim is pending. You cannot assume the rater will invent them.

Another mistake is confusing a denied old claim with a reason not to file a new condition. A denied claim is a decision-review problem. A condition you never claimed is an original or new claim. Waiting to “fix everything at once” after a denial can leave a never-claimed condition without a date.

A third mistake is missing BDD because you thought you had to be a veteran first. BDD is for service members with 180 to 90 days left. If you are in that window and you have conditions to claim, the official path is the pre-discharge claim on VA.gov, with the Separation Health Assessment — Part A, and availability for exams for 45 days after you file.

What to do this week

If you have 180 to 90 days left on active duty, start the pre-discharge claim on VA.gov. Attach the Separation Health Assessment — Part A. Keep the 45-day exam window open. That is BDD as VA described it on June 18, 2026.

If you have fewer than 90 days left, file the disability claim anyway. It will not go through BDD. It will be in VA's hands before you leave.

If you are within one year of discharge and have not filed, start the claim on VA.gov today, even if you upload only the DD214 and the records you already have. That start date, if you finish within 365 days, is the date that can protect pay from the day after discharge under § 5110(b)(1) if the claim is granted. If you refuse to file online, submit the Intent to File (VA Form 21-0966) today and complete the 21-526EZ within the year.

If you are more than a year past discharge, you can still file. There is no time limit on the original postservice claim. Start the online form or submit an Intent to File so the date stops sliding. Send current medical evidence. Old service notes help prove what happened. They do not describe how you function now.

If you already have an open claim, read the last VA letter. If it asks for records or schedules an exam, that is the work. Filing a second original claim is not a shortcut around an exam you missed.
