The financial aid calendar: FAFSA, CSS Profile, and the deadlines that cost real money
Aid forms run on their own schedule, ahead of most admissions deadlines. What opens when, whose income counts, and the mistakes that quietly cost families thousands.
The question we keep seeing
“When am I supposed to file the FAFSA, and does it matter if I'm late?”
The short answer
- File as soon as the form opens for your enrollment year — some aid is first-come, first-served.
- The FAFSA uses income from two years before you enroll, so the year to understand is already in the past.
- The federal deadline is not the one that matters. Your state and your colleges set earlier ones.
Most families treat financial aid as something that happens after admission. It doesn't. The aid calendar starts before most application deadlines, and the money that runs out early is the money you most want.
What opens when
The FAFSA for a given academic year opens in the autumn before you enroll — the target is October 1. The 2027-28 form, for students entering in autumn 2027, is scheduled to open by 1 October 2026. Confirm the current status at studentaid.gov, because recent years have seen staged rollouts and delays.
The CSS Profile, required by many private colleges for their own institutional aid, also opens in the autumn. Each college sets its own Profile deadline, and for early rounds those often land in early-to-mid November — well before you know any decision.
Whose income, and from when
The FAFSA uses income from two years before the school year — so a 2027-28 form reports 2025 income. Two consequences people miss:
- The year that counts is already over. You can't change it, but you can report a *current* hardship through an aid appeal.
- A recent job loss or income drop won't appear at all. That's precisely what professional judgment exists for.
For separated or divorced parents, the FAFSA looks to the parent who provided the most financial support. The CSS Profile often asks about both parents. Getting this wrong is one of the most common and most expensive filing errors.
Mistakes that cost money
- Not filing because you assume you won't qualify. Some aid isn't need-based, and some colleges won't consider you for their own funds without a FAFSA on file.
- Leaving schools off. List every college you're considering; adding them later delays your offers.
- Missing the CSS Profile entirely at schools that require it, which means forfeiting institutional aid regardless of your FAFSA.
- Waiting for a decision letter. Aid forms are independent of admission.
Then compare like for like
When offers arrive, compare on net price: cost of attendance minus grants and scholarships. Loans aren't aid in the sense that matters — they defer cost rather than reduce it. Katalyna's aid comparison lines up offers on that basis and flags the ones worth appealing.
