If your kid’s aid letter came back smaller or larger than expected, it is probably not a mistake. Five formula changes hit the 2026-27 FAFSA, and some of them moved real numbers.
The grandparent 529 fix alone is worth $5,000 to $20,000 in aid for some families. The sibling adjustment cut hurt others. Here is what changed, and what to do if the math is wrong for your situation.
What changed in year 2 of simplified FAFSA
The FAFSA Simplification Act, which rolled out in stages starting with the 2024-25 aid year, made its second round of formula changes for the 2026-27 aid year. Here are the five that actually moved aid letters.
Change 1: Family farm and small business assets are now partially included. Under the original simplified FAFSA, the family farm you live on and small businesses with fewer than 100 employees were fully excluded from asset calculations. The 2026-27 change partially includes these assets using a reduced assessment rate. Families with significant farm equity who got more generous aid under the initial simplification may see their Student Aid Index (SAI) rise this year.
Change 2: The sibling adjustment changed. Under the old EFC calculation, having multiple kids in college at the same time cut your expected family contribution roughly in half. Under the simplified formula, that adjustment was eliminated. Each child’s aid is calculated independently. For families with two or three college-age children, that produced real aid reductions in year 1. The year 2 change introduced a modest partial adjustment for large families (3 or more dependents), but it does not restore the previous benefit.
Change 3: Grandparent 529 accounts are now fully excluded. This is the friendliest change for many families. Previously, distributions from grandparent-owned 529 accounts were counted as student income on the FAFSA, which cut aid eligibility by 50 cents for every dollar distributed. Under the 2026-27 formula, grandparent 529 accounts and distributions are excluded entirely from the aid calculation. Families that strategically delayed grandparent 529 distributions because of this penalty can use those funds freely now.
Change 4: The income protection allowance increased. More family income is shielded from the SAI calculation before aid eligibility is assessed. For families near the aid eligibility threshold, that may open eligibility they did not have last year.
Change 5: Blended and multi-household family calculations changed. The rules for how income and assets are assessed when parents are separated, divorced, or in blended households got rewritten. Some blended families saw their SAI drop a lot. Others saw it rise. If your family structure changed or you were surprised by last year’s result, this year’s formula change is worth a fresh look.
Five places families leave aid on the table
1. Filing late. FAFSA opens October 1, and many schools have priority aid deadlines in November or December. Filing in January or February, even though the federal deadline is later, means some institutional grant money is already committed. File as early as possible.
2. Not reporting unusual expenses. If you had significant unreimbursed medical expenses, elder care costs, or job loss income in the prior tax year, document them in a professional judgment appeal. The SAI calculation uses prior-year income, but the appeal lets the school substitute current-year income.
3. Ignoring institutional aid processes. Federal aid is only one layer. Most private colleges have substantial institutional grant programs with separate application processes or requirements. The CSS Profile, required by roughly 400 colleges, captures more asset detail than FAFSA and is required by many schools that offer need-based aid from institutional funds.
4. Not negotiating after receiving offers. Comparing award letters from multiple schools and asking a school to match or improve a competing offer works more often than families realize. This is not about pressuring schools. It is providing information about competing offers and asking for reconsideration. The financial aid office handles these requests routinely.
5. Overlooking outside scholarships. Institutional financial aid may be reduced dollar-for-dollar when students win outside scholarships, but it depends on the school. Ask each school’s policy before applying. Many schools only reduce work-study or loans, not grants, when outside scholarships come in.
The appeal process in practice
Appeals work best when they are specific and documented. “Our income is lower this year” is less effective than a termination letter dated January 15, 2026, showing a $45,000 reduction in household income and a request for adjustment based on projected current-year income.
Submit appeals early. April and May are already mid-cycle for most schools. Schools with remaining flexible aid have more room to respond than schools operating at the end of their aid year.
If your family’s financial picture has actually changed, the professional judgment process is built for exactly this. Use it.
