How the FAFSA works

The Free Application for Federal Student Aid decides your eligibility for federal grants, work-study, and loans — and most colleges and states use it for their own aid too. It is free, it takes most families under an hour, and the deadline that matters is almost never the federal one.

Last reviewed August 2026. Deadlines and dollar amounts change every year — confirm anything time-sensitive on the official page linked in each section before you rely on it.

File it even if you think you will not qualify

This is the single most expensive misconception in college finance. Families skip the FAFSA because they assume they earn too much, and in doing so give up aid that has nothing to do with income.

Federal unsubsidized loans are not need-based. Many state grant programs and a large number of institutional scholarships — including merit awards — require a FAFSA on file regardless of income. Some colleges will not consider a student for their own merit money without one. There is no income cutoff above which filing is pointless, and filing costs nothing.

Timing, and the tax year that catches people out

The FAFSA for a given school year opens in the fall of the year before, and the federal deadline falls at the end of that school year. Both of those are effectively irrelevant to your planning.

What matters is that state and college deadlines come far earlier — often February or March, and in several states aid is awarded first-come, first-served until the money runs out. A technically-on-time federal filing in April can still miss a state grant that closed in February. File as soon as the form opens.

The FAFSA uses tax information from two years before the school year, not last year's. A student entering college in fall 2027 files the 2027-28 FAFSA using 2025 tax data. If your family's finances have changed significantly since then — a job loss, a death, a large medical expense — file with the required year anyway, then contact each college's financial aid office and ask about a professional judgment review. Aid officers have real discretion to adjust for current circumstances, and this is the mechanism for it.

Contributors and the FSA ID

A contributor is anyone whose information is required on the form: the student, and depending on your family structure, one or both parents or a stepparent. Each contributor needs their own FSA ID and logs in separately to give consent for their tax data to be pulled from the IRS.

Two practical consequences. First, create the FSA IDs several days before you plan to file, because accounts need to be verified. Second, the form cannot be submitted until every contributor has completed their part — if a parent is slow to log in, the application simply sits there. Chase this early.

Whose information is required depends on who the student lives with and their parents' marital status, not on who claims the student as a dependent on their taxes. That distinction confuses a lot of divorced and separated families.

The CSS Profile is a separate thing

Several hundred mostly private colleges also require the CSS Profile, a longer form run by the College Board that asks about home equity, business ownership, and non-custodial parent income. Unlike the FAFSA, it usually charges a fee, though waivers are available.

Check each college on your list for whether it requires the Profile, and note its deadline separately — Profile deadlines are frequently earlier than FAFSA ones and are commonly tied to the application round you applied in.

Only use the official site

The FAFSA is filed for free at studentaid.gov/fafsa. Sites that charge to "file" or "review" your FAFSA are not the government and offer nothing you cannot do yourself. The word "Free" is the first word of the form's name for a reason.
