If you paid into the Montgomery GI Bill and later earned the Post-9/11 GI Bill®, whether you reenlisted, moved from enlisted to officer or served six years or more in one stretch, you may be entitled to up to 48 months of education benefits instead of 36. Two court decisions changed the rule, and VA changed how it applies them on February 27, 2026. This guide covers who may qualify, what VA now does without being asked, and which program pays the extra months.
In this guide
Before 2024, if you gave up the Montgomery GI Bill to switch to the Post-9/11 GI Bill, VA generally held you to 36 months in total, or to the months you had left under Montgomery. Three steps changed that:
Rudisill v. McDonough · April 16, 2024
The Supreme Court ruled 7–2 that a veteran entitled to both GI Bills may use either one, in any order, up to the 48-month total in 38 U.S.C. § 3695.
Perkins v. Collins · May 16, 2025
The Court of Appeals for Veterans Claims held that one continuous period of service can qualify for both, as long as no time is counted twice. The airman in the case had six unbroken years.
VA's update · February 27, 2026
VA dropped its break-in-service requirement, stopped asking veterans to request a review, and dropped its October 1, 2030 claim deadline.

James Rudisill, an Army veteran with three separate periods of service, used 25 months and 14 days of Montgomery benefits for his undergraduate degree. When he wanted the Post-9/11 GI Bill for divinity school at Yale, VA limited him to the 10 months and 16 days left on his Montgomery clock. The Court said he was entitled to both, up to 48 months combined.
VA estimated in January 2025 that about 1.04 million veterans and beneficiaries could be affected by Rudisill, and in February 2026 that Perkins may reach up to 1.2 million more. Attorneys in the cases say the old service-period rule is still in VA's regulations, and veterans groups asked the U.S. Court of Appeals for the Federal Circuit to strike it in a complaint filed March 5, 2026, so details of the process could still change.
You may be in scope if all four of these are true:
You earned the Montgomery GI Bill
Usually by having $100 a month taken from your pay for your first 12 months ($1,200 in all), plus an honorable discharge and a high school diploma or equivalent.
You earned the Post-9/11 GI Bill
At least 90 days of qualifying active duty after September 10, 2001, or another route VA lists, such as a Purple Heart.
Your service covers both
Two or more separate periods of service (Rudisill), or one period long enough that different stretches of it qualify you for each program (Perkins).
You have months left to use
The 48 months count everything you have already used under both programs, and each program on its own generally pays up to 36.
Sources: VA, Montgomery GI Bill Active Duty (last updated July 24, 2026) and Impact of the Rudisill and Perkins decisions (last updated February 27, 2026). VA decides eligibility; this is a summary, not a determination.
Signs you may be affected
What does not change
Both cases involved the active-duty Montgomery GI Bill (Chapter 30). If yours is the Selected Reserve version (Chapter 1606), the 48-month total still applies; our Chapter 1606 guide covers it. For a side-by-side of the two programs, see our Montgomery vs. Post-9/11 GI Bill guide.

Since February 27, 2026, VA says you do not need to request a review. This is how its process works now:
Sources: VA, Impact of the Rudisill and Perkins decisions (last updated February 27, 2026); VA Benefits Administration notice to veterans, February 27, 2026; VA news release, March 26, 2026.
If you gave up the Montgomery GI Bill to use the Post-9/11 GI Bill, VA also recalculates your Montgomery time limit: the time you had left when you gave it up, plus 90 days, counted from your new Certificate of Eligibility. In VA's example, a veteran with seven years left, reinstated on January 1, 2025, gets a new date of March 31, 2032. Our Certificate of Eligibility guide shows where to find your months and dates.
If you are close to running out of benefits, tell your school certifying official now. Questions go to VA's Education Call Center at 888-442-4551 or Ask VA. And because VA needs no request from you, be wary of anyone who offers to file a Rudisill claim for a fee.
Each GI Bill generally pays up to 36 months on its own, so your extra months come from the program you have not finished. That matters, because the two programs pay in very different ways:
If the extra months are Montgomery (Chapter 30)
If the extra months are Post-9/11 (Chapter 33)
Sources: VA, Montgomery GI Bill Active Duty rates (last updated October 1, 2026) and Post-9/11 GI Bill rates (last updated July 31, 2026).
Which order works better? If you have already used 36 Post-9/11 months, your extra months will be Montgomery months, and a flat payment goes furthest at a lower-tuition program. If you have months left under both, the order is yours to choose, and it usually turns on cost: at a high-tuition private program, Post-9/11 months generally cover more, because VA pays the school and may add housing; at a low-tuition program, a Montgomery month at $2,601 may cover more of your costs. Ask your school certifying official to compare both before your next term is certified, because paid months are spent. Our guide to what the GI Bill covers breaks down each Post-9/11 payment.

Twelve months of full-time entitlement is roughly one and a third nine-month academic years. Here is what that can mean in practice:
Finish what you started
The last year of a bachelor's degree, if your months ran out before your credits did.
A master's degree
Many master's programs, including an MBA, run one to two academic years. See our GI Bill MBA guide.
A new direction
A graduate degree in a field that fits the career you want now.
If a graduate degree is the goal, our three partner schools offer programs built around work schedules. Westcliff University offers the MBA, MS in Computer Science, MS in Information Technology and DBA, including a Professional Weekend format with one campus residency per semester. CIAM offers a hybrid MBA in Executive Management, plus an MS in Data Analytics and an MA in Organizational Leadership that are online. Monroe University offers hybrid courses in majors including the MBA, MPA and MS in Computer Science for the Winter 2027 semester, which begins January 8, 2027.
Partner facts from each school's own materials (Westcliff military flyer, February 2026; CIAM, August 2026; Monroe hybrid-course list, September 2026). Confirm formats and VA approval with the school certifying official before enrolling.
Program format matters only for Post-9/11 months: a hybrid program with at least one in-person class per term may qualify for the resident housing rate instead of the online rate, depending on enrollment and the school's certification, while Montgomery has no separate housing allowance. Our one-class rule guide explains the difference, and the MHA calculator gives an estimate by ZIP code.
Rudisill v. McDonough is the Supreme Court's April 16, 2024 ruling that a veteran entitled to both the Montgomery GI Bill and the Post-9/11 GI Bill may use both, in any order, up to 48 months in total. VA had generally limited those veterans to 36 months.
No. Since February 27, 2026, VA reviews files automatically and mails a decision or a request for more information. Current and recent students with less than three months of benefits left are reviewed first.
Not anymore. Under Perkins v. Collins (May 16, 2025), one continuous period of service can qualify you for both programs if different parts of it meet each program's requirements. VA dropped its break-in-service requirement on February 27, 2026.
No. VA's earlier October 1, 2030 deadline no longer applies. Each program's own time limit still does, but if you gave up the Montgomery GI Bill, VA recalculates its time limit from your new Certificate of Eligibility.
Only under the usual rules. VA says the decisions do not change transfer eligibility, and a transfer must be approved while you are serving, so a veteran who has left service cannot newly transfer added Post-9/11 months.
If VA restores Montgomery benefits you were required to give up, you do not repay a $1,200 refund you already received, and if restoring them would lower your current payment, VA lets you choose.
