A veteran who served two separate stretches of duty — one that qualified for the Montgomery GI Bill and a later one that qualified for the Post-9/11 GI Bill — can now draw on up to 48 combined months of education benefits, not the 36-month ceiling that held for decades. The change traces to a 2024 Supreme Court ruling that struck down the requirement to give up one benefit before touching the other. For someone who went back to school later in a working life, the extra 12 months can mean a full added year of tuition and housing support.
The Rudisill Decision Erased the 36-Month Ceiling
Before the ruling, a veteran with two qualifying periods of service had to elect either the Montgomery GI Bill or the Post-9/11 GI Bill and formally waive the other, and the amount available under the newer program was capped at whatever Montgomery entitlement remained unused. In practice, that election, combined with how VA calculated remaining months, kept most affected veterans at or under 36 months of total education benefits regardless of how much service they had actually completed.
The Supreme Court decided Rudisill v. McDonough on April 16, 2024, holding that a veteran who separately earned eligibility for both programs through two distinct periods of service does not have to elect one and forfeit the other. VA’s own guidance now states plainly that combined Montgomery and Post-9/11 entitlement is capped by law at 48 months, not 36, though the two benefits still cannot be drawn on at the same time.
VA has said the change could reach as many as 1.04 million veterans and beneficiaries, and it launched an outreach campaign rather than wait for each of them to file a request. Roughly two-thirds of that group needed no paperwork at all, because the agency’s system could recalculate remaining entitlement on its own once the new rule was programmed in.

VA Now Reviews Files Automatically, Without a New Application
Veterans initially had to submit a request for VA to check whether Rudisill applied to their record, and some received letters instructing them to do exactly that. VA has since dropped that requirement: it now evaluates every file that might be affected on its own and either issues a formal decision or tells the veteran what, if anything, is still needed from them.
The agency also eliminated a prior application deadline. VA had initially told veterans they had until October 1, 2030 to request the expiration-date extension tied to this change; that deadline no longer applies, because the review is now automatic rather than request-driven, so no veteran can miss a cutoff for a benefit VA is required to calculate on its own.
VA prioritizes files belonging to veterans who are currently enrolled in school or were enrolled within the past six months, especially anyone with fewer than three months of benefit entitlement left, so a change in the middle of a semester does not leave a student without funding while the paperwork catches up. Veterans who previously waived Montgomery GI Bill eligibility to receive a Post-9/11 GI Bill kicker payment can have that waiver reversed, though anyone who already received a kicker will not have to repay it.
The Perkins Ruling Extended Eligibility Further Still
A second decision widened the pool again. On May 16, 2025, the Court of Appeals for Veterans Claims ruled in Perkins v. Collins that a veteran does not need two separate enlistments to qualify for both programs — a single continuous period of obligated service can be long enough to trigger separate eligibility windows for the Montgomery GI Bill and the Post-9/11 GI Bill on different months and days within that one stretch of duty.
VA is reviewing Perkins-based files under the same automatic process used for Rudisill, and no action is required from an affected veteran at this stage; the agency has said it will notify each veteran by mail once a determination is made. Because the two rulings interact, a veteran who was told years ago that no additional benefit was available under Rudisill alone may still be worth a second look once VA finishes applying Perkins.
For veterans still working through the review, the practical guidance from VA’s own published answers is to change nothing on their own: revoking a prior election can lower a current monthly payment in some cases, and VA gives affected veterans the choice of keeping their existing election if a reversal would work against them. The agency’s Rudisill and Perkins guidance page, last updated in late February 2026, remains the most current record of how the combined 48-month benefit is being applied case by case.
