Is the Montgomery GI Bill Active Duty (Chapter 30) the Same as the Post-9/11 GI Bill (Chapter 33)?

The mix-up

Veterans often mash Chapter 30 and Chapter 33 into one sentence: “the GI Bill check.” VA does not write them that way.

1. A monthly MGIB-AD deposit is treated as the same payment as Post-9/11 tuition plus housing plus books. VA's compare page splits those payment styles.
2. Eligibility for one program is treated as eligibility for the other. MGIB-AD uses published categories I–IV. Post-9/11 uses service on or after September 11, 2001, under the lanes VA lists on the Chapter 33 page.
3. Both programs are treated as something you can freely toggle for the same period of service. The compare page says the opposite for Post-9/11 / MGIB-AD / MGIB-SR.
4. A 10-year MGIB-AD clock is treated as the Post-9/11 expiration rule — or the Forever GI Bill note is applied to Chapter 30. Those clocks are written on different pages.

This page is only that split. It is not Veteran Readiness and Employment (VR&E / Chapter 31) versus Post-9/11, and it is not Fry Scholarship versus DEA. Those are different programs. Fry versus DEA is /blog/fry-scholarship-vs-dea. VR&E is on VA's VR&E page and on the same compare page.

What MGIB-AD (Chapter 30) is

From VA's Montgomery GI Bill Active Duty page (updated July 24, 2026): MGIB-AD can help you pay for education and training programs. You may be eligible if you were honorably discharged and you meet the requirements of 1 of the categories VA lists there.

Every category on that page starts from a high-school diploma, GED, or 12 hours of college credit. The rest of the gates — when you entered service, pay-reduction or contribution rules, and how long you served — change by category. Confirm the live list before you treat any category as yours.

Category I (as that page writes it)

All of these are true:

• You have a high school diploma, GED, or 12 hours of college credit, and
• You entered active duty for the first time after June 30, 1985, and
• You had your military pay reduced by $100 a month for the first 12 months of service

And you served continuously (without a break) for at least 1 of these time periods:

• 3 years, or
• 2 years if that was your agreement when you enlisted, or
• 4 years if you entered the Selected Reserve within a year of leaving active duty (called the 2 by 4 program)

Categories II–IV (headlines only)

• Category II — earlier active-duty entry (before January 1, 1977, or before January 2, 1978, under the delayed-enlistment note VA prints), service across the October 19, 1984–June 30, 1985 window with the stay-on-active-duty dates VA lists, and at least 1 day of entitlement left under the Vietnam Era GI Bill (Chapter 34) as of December 31, 1989.
• Category III — you do not qualify under I or II; pay reduced by $1,200 before separation; plus 1 of the involuntary-separation or VSI/SSB facts VA lists.
• Category IV — pay reduced by $100 a month for 12 months or a $1,200 lump-sum contribution; plus either the VEAP-account / October 9, 1996–1997 choice VA lists, or the full-time National Guard duty window and MGIB choice dates on that page.

How much you receive, as that page writes it, depends on length of service; the type of education or training program; your category (I, II, III, or IV); whether you qualify for a college fund or kicker; and how much you have paid into the $600 Buy-Up program. This note does not invent dollar rates. Check the current payment rates for MGIB-AD.

Time to use benefits: that MGIB-AD page says you usually have 10 years, and that this may change depending on your situation. The compare page writes it as 10 years from your last day on active duty.

Apply with VA Form 22-1990 (Application for VA Education Benefits) or online from the how-to-apply page. Confirm the program is approved with the GI Bill Comparison Tool. The MGIB-AD page says you then need the school or training program to certify enrollment, and you need to verify enrollment at the end of each month to keep receiving payments. Use VA's enrollment-verification page for that step.

What Post-9/11 (Chapter 33) is

From VA's Post-9/11 GI Bill page (updated July 23, 2026): the Post-9/11 GI Bill (PGIB), or Chapter 33, helps you pay for school or cover expenses while you are training for a job. If you have served on active duty after September 10, 2001, you may qualify. You may be eligible if you meet at least 1 of the requirements VA lists there.

At least 1 of these must be true, as that page writes them:

• You served at least 90 days on active duty (either all at once or with breaks in service) on or after September 11, 2001, or
• You received a Purple Heart on or after September 11, 2001, and were honorably discharged after any amount of service, or
• You served for at least 30 continuous days (all at once, without a break in service) on or after September 11, 2001, and were honorably discharged with a service-connected disability, or
• You're a dependent child using benefits transferred by a qualifying Veteran or service member

That page also lists periods of service VA considers non-qualifying — they do not count toward Post-9/11 eligibility requirements. Read the live list. This note does not invent which orders count.

Benefits, as that Chapter 33 page writes them, include:

• Tuition and fees. If you qualify for the maximum benefit, VA says it will cover the full cost of public, in-state tuition and fees. VA caps the rates for private and foreign schools and updates those rates each year. This note does not invent those caps. Check the current payment rates for the Post-9/11 GI Bill.
• Money for housing if you are in school more than half time. VA says it will base the monthly housing allowance on the cost of living where your school is located. The compare page says the housing allowance, if you are eligible, is paid to you directly every month. The Chapter 33 page also says Congress prohibits MHA during school breaks.
• Money for books and supplies, up to the maximum stipend per school year as VA writes it — not a dollar figure invented here.
• Other cost types that page lists: tutorial assistance; national exams; licensing and certification tests and prep courses; work-study; and a one-time payment that may help you move from a rural area to go to school, under the county-density and distance or flight facts VA prints.

Expiration, as that page writes it, depends on when you were discharged from active duty:

• If your service ended before January 1, 2013, Post-9/11 benefits expire 15 years after your last separation date from active service. You must use all of your benefits by that time or you will lose whatever is left.
• If your service ended on or after January 1, 2013, your benefits will not expire, thanks to a law that page names the Forever GI Bill - Harry W. Colmery Veterans Educational Assistance Act.

The compare page repeats the same January 1, 2013 split. Apply with VA Form 22-1990 or from the how-to-apply page. If you use Post-9/11 benefits, that Chapter 33 page says you need to verify enrollment every month to keep getting a monthly housing allowance or kicker payments.

Extra Chapter 33 lanes this note does not rewrite: Yellow Ribbon Program (VA's page, last updated November 15, 2024) if you need more money for higher private-school or out-of-state tuition as that program page describes it; transfer of Post-9/11 benefits (TEB; page last updated September 1, 2026) — the Chapter 33 page says a qualified service member can transfer all 36 months or a portion to a spouse or child, and that the Defense Department approves a transfer; and Fry Scholarship for a child or surviving spouse after a line-of-duty death, which is a different article: /blog/fry-scholarship-vs-dea.

How payments differ

From the compare VA education benefits page (last updated August 6, 2025):

• Post-9/11. Tuition and fees: VA sends payments to your school. Housing allowance: if you are eligible, VA pays you directly every month. Books and supplies stipend: VA pays you at the start of the enrollment period. Additional payments may include Yellow Ribbon if you are eligible and the school participates, or Tuition Assistance Top-Up if you are approved for federal Tuition Assistance through the Defense Department, as that page lists those extras.
• MGIB-AD. VA will pay you directly every month. Additional payments may include the $600 Buy-Up program if you are eligible, or Tuition Assistance Top-Up as that page lists it.

That is the payment difference. It is not a promise that one program pays more. Do not plan around a blog number. Post-9/11 current rates · MGIB-AD current rates.

One program per period of service

The compare page says you must have received an honorable discharge to be eligible for Post-9/11, MGIB-AD, and MGIB-SR. (VR&E uses a different character-of-discharge sentence on that same page — other than dishonorable — and is not this article.)

If you are eligible for GI Bill benefits, that compare page says:

• You may be eligible to get up to 36 months of benefits from 1 of Post-9/11, MGIB-AD, or MGIB-SR.
• You can use only 1 of those education benefits for a single period of service. Once you choose a benefit, you cannot switch to a different benefit for the same period of service.
• In certain situations, you may be eligible for more than 1 education benefit. But you can only get a maximum of 48 months of combined education benefits, as that page writes it. If you need help figuring out how many months you can get, VA points to Ask VA.

The GI Bill eligibility page (last updated April 3, 2026) adds this single-period note: if you have only 1 period of service that begins on or after August 1, 2011, and you qualify for other VA education benefits, you can use only 1 education benefit. You will have to choose. For example, if you choose Post-9/11 instead of MGIB-AD, that page says you cannot switch at some later date to use MGIB-AD — and if you decide to use Post-9/11, VA will refund part or all of the payments you made into MGIB-AD. The reverse example is also on that page: choose MGIB-AD instead of Post-9/11, and you cannot switch later to Post-9/11.

The MGIB-AD page also says you may be able to get a maximum of 48 months of VA education benefits — not including VR&E benefits — but many applicants are eligible for only 36 months. The eligibility page repeats that 48-month combined ceiling (4 years) when you are eligible for more than 1 education benefit, still excluding VR&E, and that many applicants are eligible for up to 36 months (3 years) only.

This note does not tell you which program to elect. Read the live pages, including each program's rates page, before that choice.

Rudisill / Perkins note (high level)

Both the MGIB-AD page and the Post-9/11 page print the same section: if you gave up your right to use MGIB-AD (Chapter 30) in the past — you “relinquished” those benefits so you could start using Post-9/11 — you may now qualify to use some of your MGIB-AD entitlement. The eligibility page also notes additional entitlement under the Rudisill decision if you have 2 or more qualifying periods of active duty and you are eligible for both programs.

As those MGIB-AD and Post-9/11 pages write the split:

• 1 qualifying period of active duty. If you served 56 months or more on active duty, you may qualify for a maximum of 48 months of benefits if you are eligible for Post-9/11 and MGIB-AD. You may be able to use up to 12 additional months of entitlement. If you served less than 56 months, generally you can use only 1 education benefit. The maximum amount of Post-9/11 entitlement is 36 months. If you decided to use Post-9/11, once you use up all your entitlement, VA will refund you part or all of the contributions you made into MGIB-AD. The maximum amount you can get for a refund is $1,200.
• 2 or more qualifying periods of active duty. You may qualify for a maximum of 48 months of benefits if you are eligible for both. If you gave up MGIB-AD when you switched to Post-9/11, you may now qualify for up to 12 months of additional MGIB-AD benefits. If you are currently using MGIB-AD and you switch to Post-9/11, you are no longer restricted to your remaining MGIB-AD entitlement.

VA says it will automatically review your entitlement and notify you if there are changes — you do not need to take any action. A reenlistment is a separate period of active duty. An extension is not. This note does not invent who qualifies on a fact pattern.

What this note is not

• Not advice on which GI Bill program to elect.
• Not a rate table. Use the live MGIB-AD rates and Post-9/11 rates pages.
• Not a rewrite of VR&E (Chapter 31), MGIB-SR, Yellow Ribbon, TEB, or Fry / DEA. Fry versus DEA is /blog/fry-scholarship-vs-dea. Yellow Ribbon lives on VA's Yellow Ribbon page.
• Not accredited representation; independent of VA; no guaranteed outcome.
