In Rudisill v. McDonough, decided April 16, 2024, the Supreme Court ruled 7-2 that veterans who separately earned entitlements under both the Montgomery GI Bill and the Post-9/11 GI Bill can use either program, in any order, up to a combined 48-month cap. The decision struck down a VA policy that had forced veterans to waive their older Montgomery benefits first and then capped their Post-9/11 access at whatever Montgomery months were left. For many veterans, the ruling unlocked up to 12 additional months of the more generous Post-9/11 benefit, and a 2025 follow-on case extended the same principle to some veterans with a single long enlistment.
What the Court Decided
James Rudisill enlisted in the Army in 2000 and reenlisted twice, serving roughly eight years across three separate periods of active duty. His first period earned him 36 months of Montgomery GI Bill benefits. His later periods separately earned him 36 months under the Post-9/11 GI Bill. Both entitlements are subject to a 48-month aggregate cap under 38 U.S.C. § 3695, so Rudisill should have been able to use up to 48 months total across the two programs.
The VA disagreed. Under its policy at the time, a veteran switching from the Montgomery GI Bill to the Post-9/11 GI Bill had to formally waive the older benefit, and the VA then limited Post-9/11 entitlement to whatever months remained on the Montgomery clock rather than treating Post-9/11 as independently earned. A veteran who had used 24 months of Montgomery benefits, for example, was told they could access only 12 months of Post-9/11 funding, not the 24 months that a plain 48-month cap would allow.
Justice Jackson, writing for the majority, held that the statute’s “election” provision was meant to prevent double-dipping for the same period of service, not to penalize veterans who served multiple tours. Veterans who accrue benefits under both programs through separate periods of service may use either one, in any order, up to the 48-month aggregate cap.
Perkins v. Collins Extended the Ruling to Single-Enlistment Veterans
Early summaries of Rudisill suggested the ruling helped only veterans with multiple enlistments separated by a break in service. That changed on May 16, 2025, when the U.S. Court of Appeals for Veterans Claims decided Perkins v. Collins. The court held that a veteran whose single period of service is long enough to independently satisfy the eligibility requirements for both the Montgomery GI Bill and the Post-9/11 GI Bill, without counting any days of service twice, is entitled to benefits under both programs up to the same 48-month cap.
In practice, a veteran who served one continuous enlistment of roughly six or more years may qualify for both programs, so long as the months of service supporting each entitlement do not overlap. The VA has acknowledged this expansion and is incorporating Perkins into its benefit reviews alongside Rudisill.
Who Qualifies Now
The core requirement is that your service history independently supports eligibility for at least two GI Bill programs. For a veteran with multiple enlistments, each enlistment separately meets the active-duty thresholds for one of the programs. For a single-enlistment veteran under Perkins, the total service is long enough that different portions of it independently qualify for each program without double-counting any days.
Post-9/11 GI Bill eligibility requires at least 90 aggregate days of active duty after September 10, 2001, with full benefits at 36 months of aggregate active duty. Veterans discharged for a service-connected disability after at least 30 continuous days also qualify at the full benefit level. National Guard members can qualify through federal activation under Title 10 or full-time National Guard duty under Title 32.
Discharge status matters. The Montgomery GI Bill specifically requires an honorable discharge, and GI Bill programs generally do. An other-than-honorable, bad conduct, or dishonorable discharge may disqualify you, though you can pursue a discharge upgrade or a VA Character of Discharge review. If you served honorably during one period and received a less favorable discharge from a later period, you can still claim benefits earned during the honorable period.
How Much the Extra Months Are Worth
The Post-9/11 GI Bill is substantially more valuable than the Montgomery GI Bill because it pays tuition directly and includes a housing stipend. For the 2026–2027 academic year, it pays up to $29,920.95 in annual tuition and fees at private institutions and covers full in-state tuition at public schools. Full-time students attending in person receive a Monthly Housing Allowance based on the military E-5 Basic Allowance for Housing rate for their school’s zip code; the national average MHA for 2026 is $2,522 per month. Students also receive up to $1,000 per year for books and supplies.
For a veteran unlocking the maximum 12 additional months of Post-9/11 benefits, the financial impact is significant. Housing alone at the national average comes to roughly $22,700 over a nine-month academic year. Add tuition at a moderately priced school and the books stipend, and an extra year of Post-9/11 coverage is realistically worth $30,000 to $55,000 depending on the institution and location.
The 48-Month Cap and One Exception
Federal law caps total educational assistance across multiple VA programs at 48 months, or its part-time equivalent. Each individual program still maxes out at 36 months on its own. The practical effect of Rudisill is that qualifying veterans can stack up to 12 additional months of Post-9/11 GI Bill benefits on top of 36 months already used under the Montgomery GI Bill, or any other combination that fits under 48 months total.
One exception: veterans receiving Vocational Rehabilitation and Employment benefits under Chapter 31 can exceed 48 months if the VA determines additional time is necessary to complete their rehabilitation program.
Watch the Expiration Date
Whether your Post-9/11 GI Bill benefits expire depends on when you separated from active duty. If your last day of active service was on or after January 1, 2013, your benefits never expire. The Harry W. Colmery Veterans Educational Assistance Act of 2017, commonly called the Forever GI Bill, eliminated the 15-year delimiting date for this group.
Veterans who separated before January 1, 2013, must use their Post-9/11 GI Bill benefits within 15 years of their last discharge date or lose the remaining entitlement. If Rudisill just unlocked additional months for you and you fall into this group, check the calendar. For someone discharged in late 2012, the deadline would be late 2027.
How the VA Is Handling Claims After Rudisill and Perkins
You no longer need to file a special request or application for the VA to review your eligibility under Rudisill or Perkins. The VA has committed to automatically evaluating all affected veterans’ files and issuing formal decisions without requiring any action from the veteran. The previously announced October 1, 2030, deadline to apply no longer exists.
The VA is prioritizing veterans currently enrolled in school or those enrolled within the past six months, especially those with fewer than three months of benefits remaining. If you previously applied for benefits, the VA will notify you by mail that your application was received and is pending until your file is reviewed.
Automatic reviews for all affected veterans will take time. If you want to move things along, you have two options. You can submit a new application using VA Form 22-1990 through VA.gov, specifying which periods of service support which program. Or, if you previously received a VA decision denying you additional benefits under the old policy, you can file a supplemental claim using VA Form 20-0995 and reference the Supreme Court decision, including the April 16, 2024, ruling date, on the form.
Applying for the Additional Months
Gather your DD Form 214 for each period of service. These documents establish the start and end dates of each tour, which is how the VA determines whether your service periods independently qualify for different programs. You will also need your Social Security number, bank account information for direct deposit, and the name and address of the school you plan to attend.
Complete VA Form 22-1990 online at VA.gov. Pay close attention to the sections about which benefit program you are electing and whether you are relinquishing another. Clearly specify which dates of service apply to which program so the VA does not mistakenly treat your request as a standard one-for-one swap.
The VA currently processes education benefit claims in an average of about 30 days. After review, the VA issues a Certificate of Eligibility showing how many months and days you have remaining. Provide that certificate to your school’s certifying official to begin receiving tuition payments and stipends, and track your claim status through the VA.gov portal.
