Even tiny mistakes on the FAFSA can delay your aid, lower your award, or even cause you to miss out entirely. With the 2025–26 FAFSA rollout already showing glitches and confusion, catching errors early is more important than ever.Before you go further, double-check the FAFSA 2025–26 deadlines & income limits so you don’t miss out on aid.
Here’s the deal: nearly 1 in 3 FAFSA applications has some kind of error, according to Federal Student Aid data. In past years, that’s usually been things like entering the wrong income number or forgetting a signature.
But this year’s form (the 2025–26 FAFSA) is coming off a messy transition — the Department of Education already warned about processing delays and new system errors.
Parents on Reddit have been sharing stories of “frozen” applications, missing Student Aid Index calculations, and deadlines creeping up while they wait.
Based on what I’ve seen students and parents share in FSA alerts, Reddit FAFSA help threads, and even local high school counselor updates, the 2025 FAFSA cycle feels especially high-stakes.
In my opinion, this isn’t the year to wing it — you want to avoid common errors before they snowball into missed grants or delayed aid packages.
What Are the Most Common FAFSA Mistakes in 2025–26?
Even though the FAFSA is supposed to be simpler this year, students and parents are still tripping over the same mistakes. Here’s what most parents miss — and why fixing them early matters:
List of mistakes :
- Wrong SSN or name mismatch
- Incorrect tax info (using the wrong year, typos)
- Missing parent/student signatures
- School list errors (leaving schools off, wrong codes)
- Misreporting assets/income
- Skipping deadlines (or waiting too long)
- Not creating an FSA ID correctly
- Leaving required fields blank
- Using the wrong year’s tax return
- Forgetting to re-submit corrections
Avoid these mistakes — see the FAFSA 2025–26 deadlines for the latest dates.
Most of these errors happen because families are rushed, overwhelmed, or think “close enough” is fine. But FAFSA doesn’t forgive sloppy details.
For example, I’ve seen Reddit threads where students panicked after realizing they put their nickname instead of their legal name — which caused weeks of delays. And a USNews piece even ranked the “wrong tax info” issue as one of the top mistakes costing families aid.
Avoid rushing your FAFSA — these tools help you track documents and deadlines.
FAFSA 2025–26 Common Error Impact

❌ FAFSA Mistake #1: Wrong Social Security or ID Info
One of the fastest ways to derail your FAFSA is entering the wrong Social Security Number (SSN) or having your name not match what’s on your Social Security card. The system will flag the error, and your application won’t process until it’s fixed.
This usually happens because of typos, missing digits, or using a nickname instead of a legal name. Honestly, I think this is the #1 mistake that causes the most panic — but the good news is, it’s almost always fixable.
The official fix is to log in at studentaid.gov, submit a correction, and re-certify the form. If the error is tied to the SSN itself, you may need to contact the Social Security Administration.
In my experience, this one mistake has caused students to delay their aid packages by a month or more. But I’ve also seen Quora threads where parents shared that after correcting the SSN online, their aid still came through before school started.
Small data errors (like GPA misreports or SSN typos) can snowball in applications. Here’s a quick refresher on understanding how your GPA impacts aid & admissions.
👉 Can I fix my FAFSA SSN after submission?
Yes, but only through official correction — you cannot just email or call it in.
❌ FAFSA Mistake #2: Wrong or Missing Tax Information
Using the wrong tax info is another huge FAFSA roadblock. The 2025–26 FAFSA uses 2023 tax year data, and if you guess or pull numbers from the wrong year, your Student Aid Index will be off.
Families often enter “ballpark” income numbers because they’re in a hurry — I’ve seen this a lot in FAFSA help forums. Honestly, that backfires. If your numbers don’t match what the IRS has, colleges may flag your application for verification (which delays aid even further).
The safest route is to use the IRS Data Retrieval Tool (DRT) built into the FAFSA, which pulls the exact numbers.
The IRS itself explains the Data Retrieval Tool process here, and Federal Student Aid strongly recommends it.
In my opinion, this mistake feels scary because people think they’ve “ruined” their aid chances — but usually, it’s just a matter of correcting the income info and re-submitting.
Using outdated or incomplete tax info is a big reason why FAFSAs get flagged. Always import tax details directly from the IRS Data Retrieval Tool when possible.
If FAFSA feels overwhelming, remember — there are other types of aid out there too. For example, here’s a guide on how to apply for financial aid with Coursera for online courses.
👉 What happens if I used the wrong tax year on FAFSA?
You’ll need to correct it online with the right year (2023 for 2025–26). Schools won’t finalize aid until it matches.
❌ FAFSA Mistake #3: Missing Signatures (Student or Parent)
If the FAFSA isn’t signed, it isn’t valid. Students always need to sign, and if you’re a dependent student, at least one parent must sign with their own FSA ID. Forgetting this step can put your application in limbo for weeks.
This mistake happens all the time because parents think the student’s signature covers everything. Nope — if you’re considered dependent (and most students under 24 are), your parent’s digital signature is required too.
The fix is simple: log back in with the correct FSA ID and e-sign. Honestly, it’s one of the most frustrating mistakes because it feels so minor, but it can cost you weeks of aid processing.
I remember reading a Reddit FAFSA thread where a parent admitted they thought their student had “finished” everything, only to discover three weeks later that the missing parent signature froze the whole application.
Students sometimes list only their top-choice schools. But FAFSA lets you list multiple schools, and skipping options can limit your aid offers.
Don’t forget to include FAFSA-friendly online colleges in your list, even if they’re backups. And if you’re still refining your choices, check out this school selection guide to build a strong, strategic list.
❌ FAFSA Mistake #4: Listing Too Few or Wrong Colleges
For the 2025–26 FAFSA, you can list up to 20 schools. Leaving schools off, using the wrong school code, or not adding enough backups can mean missing out on federal and state aid.
In my opinion, this is the sneaky one most students don’t even think about. If you only list your “dream school” and forget backups, you could lose out on state-specific grants or college aid. Luckily, you can log in anytime before the deadline and add more schools. The safest move? Always add at least one local public option and a few backups, even if you’re not sure you’ll attend.
You can find the official codes in the College Board FAFSA School Code List.

Table — How Many Schools Can You List on FAFSA 2025–26?
| FAFSA Year | Max School Limit | Tip |
|---|---|---|
| 2024–25 | 10 schools | Old limit |
| 2025–26 | 20 schools | Add all potential colleges — no downside! |
| 2026–27 (expected) | TBD | Keep updated at studentaid.gov |
Adding more schools doesn’t hurt your eligibility — it actually helps maximize your state and institutional aid.
❌ FAFSA Mistake #5: Misreporting Assets or Untaxed Income
Reporting assets and income is confusing — especially when it comes to things like 529 plans, child support, or retirement savings. Mistakes here can get your FAFSA flagged for verification.
The big confusion usually comes down to:
- 529 Plans: Counted as a parent asset if the parent is the account owner.
- Retirement Accounts: Not reported.
- Child Support Received: Must be reported as untaxed income.
- Savings Bonds/Investments: Yes, they count as assets.
I’ve seen students try to “play it safe” by under-reporting, but that backfires. One Reddit student shared that they didn’t list a 529 correctly, and their school flagged them for verification — adding weeks of delay.
The official rules are outlined in the Federal Register Verification for 2025–26.
From what I’ve seen, families often think retirement accounts will hurt them if they’re reported. They won’t — FAFSA doesn’t touch those. But savings accounts, even if they’re “for emergencies,” still count.
Families often underestimate or over-report savings and assets, leading to incorrect aid calculations.

FAFSA Mistakes 2025–26: Final Tips for Parents & Students
Look, FAFSA mistakes happen — it’s not the end of the world. The key is to catch the error, correct it fast on StudentAid.gov, and call your school’s financial aid office to make sure it’s updated on their end.
Most families stress way too much about “breaking” the FAFSA. In reality, almost every error can be fixed — from a wrong Social Security digit to forgetting to add a college. In my opinion, the smartest move is not panicking but staying proactive. Check your FAFSA Submission Summary (FSS) for flags, make corrections, and follow up with the aid office.
I’ve seen parents on Reddit admit they thought a single typo ruined their kid’s aid chances. Nope — corrections are common and expected. What matters is not ignoring them.
