How to Fill Out the FAFSA: A Step-by-Step Walkthrough for Families

The Bottom Line

Create StudentAid.gov accounts for the student and every required contributor weeks before the FAFSA opens, because identity verification can take days. Gather your 2025 tax return, balances, and college list before you sit down. When you fill out the form, every contributor must provide consent and approval for the IRS data transfer, or your student is not eligible for federal aid at all. Submit early. State and college deadlines come long before the federal one.

The FAFSA is one of those tasks that sounds simple until the night you sit down to do it.

The form itself has gotten shorter. Most of the tax data now comes straight from the IRS. And yet every October, families hit the same walls: an account that will not verify, a step that will not unlock until someone else finishes theirs, and a consent-and-approval screen nobody warned them about.

This walkthrough covers the whole process for the 2027-28 FAFSA, the one Class of 2027 students will file. It is written for families doing this for the first time. No assumed knowledge, no jargon without a definition.

Before You Start: Do These Two Things in the Summer

The single best thing you can do for your October self happens in July or August.

Create StudentAid.gov accounts now. The student needs one. Each required contributor, which for most families means at least one parent, needs their own separate account. The account username and password combination is often called an FSA ID, and Federal Student Aid says it serves as your legal electronic signature on the form.

Two things about these accounts trip families up:

  • Creating one requires identity verification, which can involve matching your information against Social Security Administration records. Sometimes it is instant. Sometimes it takes several days, and some people are asked to provide additional documentation.
  • Accounts cannot be shared. A parent signing with a student's login, or the reverse, causes real problems later. One person, one account.

If you wait until October 1 to create accounts, you may not be able to file that day. If you create them in August, this entire step disappears.

Know the FAFSA's timing. The 2027-28 FAFSA is scheduled to open October 1, 2026, and the U.S. Department of Education has said it is on track for that date. Recent cycles have taught families to verify rather than assume, so check StudentAid.gov in September for the confirmed date.

Who Counts as a Contributor

The FAFSA uses the word "contributor" for anyone required to provide information on the student's form. Depending on your family, that is:

  • The student, always
  • The student's spouse, if the student is married
  • One or both parents, depending on your household

For married parents filing jointly, one parent can usually handle the parent section. For divorced or separated parents, the FAFSA has specific rules about which parent participates, and they may not match what you expect from custody arrangements. Federal Student Aid's guidance on reporting parent information walks through the scenarios, and it is worth reading before October if your family's situation is not simple.

Here is why this matters early: every contributor needs their own StudentAid.gov account, and every contributor has to complete and sign their own section. If the required parent is hard to reach, start that conversation now, not the week a deadline hits.

What to Gather Before You Sit Down

Most of this list takes ten minutes to assemble and saves an hour of hunting mid-form:

  • Social Security numbers for the student and contributors
  • Your 2025 federal tax return. The 2027-28 FAFSA uses prior-prior year taxes, so the return you filed in early 2026 is the one that counts
  • Current balances for cash, savings, and checking accounts. The form asks for values as of the day you complete it, so pull fresh numbers when you sit down
  • Records of investments and businesses, where applicable. Retirement accounts are generally not reported, but check the form's instructions for your situation
  • The student's college list. The online form lets you send results to up to 20 schools, and adding every school under consideration costs nothing

Keeping all of this in one place is exactly the kind of thing CollegeHound was built for. CollegeHound is free and gives your family one shared place for the college list, deadlines, and financial aid to-dos so nothing lives on a sticky note. And when you are not sure what a term like SAI means for your student, you can ask Scout, our paid AI guide, which can draw from what your family has saved in CollegeHound to explain what it means for your student.

The Step-by-Step Walkthrough

Step 1: The student starts the form. The student logs in at StudentAid.gov and begins the FAFSA. They complete their own personal and school sections and identify their contributors. Under the current process, contributors are then invited to complete their own portions; expect the final 2027-28 instructions to spell out the exact sequence when the form is published.

Step 2: The student provides consent and approval for the IRS data transfer. More on this in the next section, because it is the step families most often misunderstand.

Step 3: The student lists colleges. Add every school your student is seriously considering, even ones they are unsure about. Schools only see that they received the FAFSA. Removing a school later is easy. Missing a school's aid deadline because it was not listed is not.

Step 4: Contributors complete their sections. Each invited contributor logs in with their own account, fills in their portion, provides their own consent, and signs. The form is not done when the student finishes. It is done when everyone finishes.

Step 5: Sign and submit. Each person's account login serves as their signature. Once every section is signed, the form can be submitted. Save the confirmation.

If the accounts exist and the documents are gathered, the form itself usually takes less than an hour. Truly.

During the form, the student and every contributor will be asked to provide what Federal Student Aid calls "consent and approval" for the transfer of their federal tax information from the IRS.

This is not a formality, and it is not optional.

Under the FUTURE Act, Federal Student Aid is explicit: if a required contributor does not provide consent and approval for the IRS data transfer, the student is not eligible for federal student aid. Typing the tax numbers in by hand does not fix it. The consent and approval itself is the requirement.

For most families this is good news in disguise. Consent means the IRS sends the tax data directly through a secure exchange, so there is less manual entry and fewer typos to correct later. But every year, some families lose aid eligibility because one contributor declined, thinking they were protecting their privacy. If a contributor in your family has concerns, talk it through before October, because the alternative is no federal aid at all.

After You Submit

Within days of submitting, your student receives a FAFSA Submission Summary. Read it. It shows what was submitted and includes the Student Aid Index, or SAI, the number colleges use to help determine need-based aid. In general, a lower SAI indicates greater financial need.

Three things to know about this stage:

  • The SAI is not a bill, and it is not what you will pay. It is an input colleges use alongside their cost of attendance to build your student's aid offer.
  • Corrections are possible. If something is wrong on the summary, the form can be reopened and fixed.
  • Some students are selected for verification, where a college asks for documents confirming FAFSA data. It is common and usually routine. Respond quickly, because aid cannot finalize until it is done.

The actual aid offers arrive from each college, typically alongside or after admission decisions. Our guide to what financial aid award letters actually include covers how to read them, and if an offer falls short, you can appeal with a letter.

What Delays Families the Most

After watching families go through this cycle after cycle, the same four delays come up:

  • Last-minute account creation. Identity verification takes days for some people. This is the number one avoidable delay, and the fix is doing it in the summer.
  • The waiting-on-a-contributor stall. The student finishes their part in twenty minutes, then the form sits for three weeks waiting on a parent section. Put a date on the calendar for every contributor, not just the student.
  • Identity mismatches. A name that does not exactly match Social Security records, a wrong birthdate, a transposed SSN digit. Slow down on the identity fields. Exact matches only.
  • The skipped consent and approval. Covered above. It cannot be worked around after the fact without redoing that step.

The Deadlines That Actually Matter

The federal deadline for the 2027-28 FAFSA is expected to be June 30, 2028, following the standard cycle pattern. Ignore it. It is the last possible moment, not a target.

The deadlines that matter come much earlier:

  • State deadlines. Some state grant programs award aid until the money runs out, which makes filing early worth real dollars. Federal Student Aid publishes state deadlines for every state.
  • College priority deadlines. Many colleges set priority financial aid deadlines in the late fall or winter, and some CSS Profile schools want forms as early as November. Check each school on your student's list, and if any require the CSS Profile, our FAFSA vs. CSS Profile guide explains the difference.
  • Scholarship deadlines. Some merit scholarships require a filed FAFSA even when they are not need-based.

The practical rule: file as close to opening day as your family reasonably can. For the full season view of what to file and when, see our financial aid timeline for the Class of 2027.

Frequently Asked Questions

When does the 2027-28 FAFSA open?

The 2027-28 FAFSA, for students entering college in fall 2027, is scheduled to open October 1, 2026. The U.S. Department of Education has said it is on track for that date, but families should confirm at StudentAid.gov in September, since past cycles have seen delays.

What is a FAFSA contributor?

A contributor is anyone required to provide information on the student's FAFSA: the student, the student's spouse if married, and one or both parents depending on the family's situation. Every contributor needs their own StudentAid.gov account and must provide their own consent and approval for the IRS data transfer.

What happens if a parent refuses consent and approval on the FAFSA?

If any required contributor declines to provide consent and approval for the IRS data transfer, the student is not eligible for federal student aid, even if that contributor types their tax information in manually. Consent and approval is a legal requirement of the form, not an optional shortcut.

What tax year does the 2027-28 FAFSA use?

The FAFSA uses prior-prior year tax information. For the 2027-28 form, that means your 2025 tax return. By fall 2026 most families' 2025 taxes are already filed, and in most cases the form pulls that data directly from the IRS after you provide consent and approval.

How long does the FAFSA take to fill out?

If the accounts exist and the documents are gathered, most families finish in under an hour, and the IRS data transfer removes most of the manual tax entry. The delays come from creating accounts at the last minute, waiting on a contributor to complete their section, or fixing identity mismatches.
