Key Takeaways

• The TAG filing window is September 1–30. There are no extensions and no late submissions — miss it and the guarantee is gone for a full year.
• TAG is filed through the UC Transfer Admission Planner (UC TAP), a separate system from the UC application itself. Filing TAG does not apply you to UC.
• You can hold a TAG at one campus only. Choosing which one is the real decision, and it should be made before September, not during it.
• Six campuses participate: Davis, Irvine, Merced, Riverside, Santa Barbara, and Santa Cruz. UCLA, Berkeley, and San Diego do not offer TAG.
• Filing TAG does not replace the UC application. You still apply October 1 – November 30, and on your UC application, the primary major you choose for your designated TAG campus must match your TAG major exactly.

Every September, a handful of families discover that the guarantee they had been counting on for two years expired while they were still deciding.

The UC Transfer Admission Guarantee is one of the few genuinely certain things in an otherwise uncertain process. If a student meets the criteria, admission to a participating campus is contractual rather than hopeful. But that certainty comes with a filing window that is short, absolute, and easy to lose track of in the middle of a fall semester.

This is a walkthrough of how to file, what to confirm before you do, and where the process most often goes wrong.

The Deadline

The TAG application opens September 1 and closes September 30.

Not “around the end of September.” September 30. UC does not extend the TAG window, does not accept late submissions, and does not make exceptions for technical problems on the final day.

If a student misses it, the guarantee is unavailable until the following year’s cycle. They can still apply to UC through the regular transfer process — and roughly two-thirds of admitted UC transfer students do — but the guarantee itself is gone.

Practical advice: file in the first two weeks of September. The system is busiest in the final days, questions take time to resolve, and there is no benefit whatsoever to waiting. Additionally, you can change your TAG campus and major after you submit, but only until September 30.

Before You File: Four Things to Confirm

Most TAG problems are decided before the application is ever opened. Work through these first.

1. Is your student eligible?

TAG is available only to California community college students. Students transferring from a four-year university, a CSU, or an out-of-state college are not eligible — though all of those students can still transfer to UC through the regular application. Students who previously attended a UC and intend to return to that same campus are also excluded, as are students who have already earned a bachelor’s degree and students still concurrently enrolled in high school at the time of submission.

There are also unit and GPA thresholds that must be met by specific terms, and they vary by campus and by major. Here is where each campus currently sets the bar:

Campus	Minimum UC-transferable GPA	Required by
Davis	3.2 for Agricultural & Environmental Sciences, Biological Sciences, and Letters & Science; 3.5 for Engineering	End of summer 2026
Irvine	3.4, all majors	End of fall 2026
Merced	2.8 for Social Sciences, Humanities & Arts; 2.9 for Natural Sciences; 3.0 for Engineering, Psychology, and Public Health	End of summer 2026
Riverside	2.7 for Education and Public Policy; 2.8 for CHASS, Natural & Agricultural Sciences, and Business; 3.0 for Engineering — with higher bars on selective majors, up to 3.6 for Computer Science	End of summer 2026
Santa Barbara	3.4, all majors	End of fall 2026
Santa Cruz	3.0, all majors	End of summer 2026

A few notes on reading that table. These are minimums to qualify for the guarantee, not competitive averages — admitted students frequently sit well above them. Several campuses also set a separate GPA requirement on major-preparation coursework specifically, which is not reflected above. And Riverside in particular has a wide spread within a single college: Computer Science requires a 3.6 while the rest of the engineering school requires a 3.0.

Confirm your student’s numbers against page 2 of the UC TAG Matrix and against the campus’s own TAG page before assuming eligibility. The figures above are drawn from UC’s 2027–28 matrix, accurate as of June 9, 2026, and are subject to change.

2. Is your student’s major still TAG-eligible at that campus?

This is where families get hurt, and it is worth being blunt about.

TAG-eligible major lists change from cycle to cycle. A student can spend two years building toward a major that quietly loses its guarantee before they file. UC Irvine’s expanded list of excluded majors for fall 2028 is the clearest recent example — a long list of popular Biological Sciences, Engineering, Psychology, and Economics majors that will no longer carry a guarantee.

Check the exclusion list for the specific cycle your student is applying in, not the current one. They are not always the same.

3. Which campus?

A student can hold a TAG at only one campus. This is the single most consequential decision in the process, and it deserves more thought than it usually gets.

The instinct is to choose the most selective participating campus. That is not always right. A guarantee at a campus your student would genuinely attend is worth more than a guarantee at a campus they would decline — and TAG eligibility varies enough by major that the strongest guarantee is not always at the most recognizable name.

Worth working through:

• Would the student actually enroll there? A guarantee they would turn down has no value.
• Is their intended major TAG-eligible at that campus for their cycle?
• Are the GPA and coursework requirements realistically achievable by the deadline?
• Is there a campus where the guarantee is more attainable and the fit is comparable?

Because TAG covers only one campus, the other applications still matter. A well-constructed transfer plan uses TAG to secure a floor, then applies broadly above it — including to UCLA, Berkeley, and San Diego, which offer no TAG at all.

4. Is the coursework on track?

TAG requires specific coursework completed by specific terms, and requirements can differ by campus and major. Use ASSIST.org to confirm that the courses your student has taken and is currently enrolled in actually satisfy the requirements at the target campus.

Discovering a gap in September is survivable. Discovering it in January is not.

Filing: Step by Step

Step 1 — Create or update a UC TAP account

The TAG application is submitted through the UC Transfer Admission Planner (UC TAP), at uctap.universityofcalifornia.edu.

UC TAP is a coursework-tracking tool that students ideally start using well before their TAG year. If your student already has an account, log in and confirm the record is current. If not, create one now — you will need to enter their full academic history before you can file.

UC TAP is separate from the UC application. They are different systems with different logins.

Step 2 — Enter all coursework

Every course from every college attended, including in-progress and planned courses. This is the most time-consuming step and the one most worth doing carefully.

Two common errors:

• Omitting a college. Every institution attended must be listed, including dual enrollment during high school. Omissions surface later during verification.
• Guessing at planned coursework. Spring courses should reflect what the student will realistically take, not an optimistic plan. Changes are possible, but the initial entry should be honest. Additionally, the student should ensure that any changes still qualify them for TAG consideration.

Step 3 — Select your TAG campus and major

Choose from the majors at one of the six participating campuses. Again — one only.

Step 4 — Complete the campus-specific checklist

Each campus asks students to confirm eligibility requirements, such as confirming the student will complete one UC-transferable math course by the end of the fall semester. Each campus also has its own questions: some require major selection at this stage, some ask about coursework in progress, and a few ask short written responses. Carefully review the checklist to ensure eligibility, so there are no surprises later.

Step 5 — Review and submit

Before submitting, check:

• Every college attended is listed
• All in-progress and planned coursework is entered
• The selected major matches what will go on the UC application
• GPA calculations are accurate
• Contact information is current
  

Submit, then save the confirmation.

Step 6 — Watch for the campus response

The campus reviews the TAG application and responds with an agreement, a conditional agreement, or a denial. Read whatever comes back closely — a conditional agreement carries specific requirements that must still be met.

Note that Davis, Merced, Riverside, and Santa Cruz provide a pre-evaluation of coursework as part of TAG and ask students to wait for the TAG decision before submitting the UC application. Irvine and Santa Barbara do not.

After You File

Filing TAG is not applying to UC. This is the single most common misunderstanding, and it is a costly one.

Three things still have to happen:

1. Submit the UC application, October 1 – November 30. Separate system, separate deadline. The TAG campus must be among the campuses applied to, and the primary major on the UC application for that campus must match the major on the TAG. A mismatch can void the guarantee.

2. Submit the Transfer Academic Update by January 31. This is where fall grades are reported and spring classes are confirmed. It is required, it is easy to forget over winter break, and missing it puts the guarantee at risk.

3. Meet every condition through spring. TAG is conditional on final coursework and GPA. A spring semester that falls below the agreement’s terms can void it — which is why the shared TAG criteria specify that students earn no grade lower than a C in the fall, winter, and spring terms, not just a passing overall average.

Common Mistakes

• Filing on September 29 or 30. No margin for a technical problem or an unanswered question.
• Assuming last year’s major list still applies. Exclusion lists change. Check the list for your student’s specific cycle.
• Choosing the campus by prestige rather than fit. A guarantee the student would decline is not a guarantee.
• Letting the majors drift apart. TAG major and UC application primary major for that campus must match.
• Treating TAG as the whole strategy. Two-thirds of admitted UC transfer students don’t have one. TAG secures a floor; it doesn’t replace a well-built application.
• Forgetting the TAU in January. It arrives in the middle of winter break, and it is required.

What To Do Now

If your student is filing this September:

• Confirm eligibility, major, and coursework this month — before the window opens
• Log into UC TAP now and update the coursework record
• Decide the campus before September 1
• File in the first two weeks

If your student is a year out:

• Start using UC TAP now, not in the TAG year
• Check the exclusion list for their cycle, and re-check it annually
• Verify major prep against ASSIST.org for the specific target campus
• Understand that course selection this year determines eligibility next year

If your student isn’t TAG-eligible:

• The regular transfer path is the majority path, not a fallback
• UCLA, Berkeley, and San Diego are reached this way by everyone
• Major preparation and PIQ strategy carry more weight without a guarantee

Frequently Asked Questions

When is the TAG deadline for fall 2027 admission? September 1–30, 2026, filed through UC TAP. No extensions, no late submissions.

Which UC campuses offer TAG? Davis, Irvine, Merced, Riverside, Santa Barbara, and Santa Cruz. UCLA, UC Berkeley, and UC San Diego do not.

What GPA do I need for a UC TAG? It depends on the campus and major. For the 2027–28 cycle the minimums range from 2.7 at UC Riverside to 3.5 at UC Davis for Engineering, with Irvine and Santa Barbara at 3.4 and Santa Cruz at 3.0 across all majors. See the table above for the full breakdown.

Can I TAG with more than one campus? No. One campus only.

Does filing a TAG mean I’ve applied to UC? No. The UC application is separate and is submitted October 1 – November 30. Both are required.

What happens if I miss the September 30 deadline? The guarantee is unavailable for that cycle. The student can still apply through the regular transfer process, which is how roughly two-thirds of admitted UC transfer students get in.

Can I change my major after filing? The TAG major and the UC application major must match. Changing after filing risks the guarantee — talk to the campus TAG counselor before making a change.

Is TAG available to students transferring from a four-year college? No. TAG is for California community college students only.

Not Sure Which Campus to TAG?

The filing itself is administrative. The decision underneath it — which campus, which major, and whether TAG is even the right lever for your student — is where the outcome is actually determined.
