Which parent's income the FAFSA requires depends on custody and living arrangements, not divorce status alone

The FAFSA asks for the income of whichever parent the student lived with more during the past 12 months. If the student lived equally with both parents, the form asks for the parent who provided more financial support. Divorce itself does not automatically require both parents' information — only the parent (or parents) who meet that living or support test.

The form does not ask "are your parents divorced?" It asks "with whom did you live?" This distinction matters because it means a student whose parents are married but separated, or whose parents are divorced but share custody equally, follows the same rule: report the parent the student actually lived with more.

If both parents provided equal support and the student lived with both equally, you will need both parents' financial information. This is rare but does happen in genuinely equal shared-custody arrangements.

Key Takeaways

  • The FAFSA requires income from the parent the student lived with for more than half the past 12 months, regardless of whether the parents are married or divorced.
  • If the student lived equally with both parents, report the parent who provided more financial support during that time.
  • If both parents provided equal support and the student lived with both equally, you will need both parents' tax returns and financial information on the form.
  • The parent reported on the FAFSA is called the "custodial parent," and their spouse's income (if they have remarried) may also be required.
  • If the custodial parent has remarried, the stepparent's income counts on the FAFSA even if the stepparent did not support the student.

How the FAFSA defines "living with a parent"

The FAFSA counts nights the student actually spent in each parent's home during the 12 months before submitting the form. A student who spent 200 nights with one parent and 165 nights with the other lived with the first parent "more than half the time," even if the difference is small.

Overnight visits, school breaks, and summer months all count toward this total. If the student was away at boarding school or a residential program, the nights spent at each parent's home during school breaks and summers are what matter.

If the student lived with one parent for part of the year and the other parent for another part — for example, school year with one parent and summers with the other — add up the total nights for the full 12 months. The parent with more nights is the one to report.

What happens if parents share custody equally

In a true 50-50 custody arrangement, the student lived with each parent roughly the same number of nights. In this case, the FAFSA asks you to report the parent who provided more financial support during the past 12 months. "Financial support" means who paid for housing, food, clothing, and other living expenses — not who paid for college.

If both parents provided equal financial support, you will need to include both parents' income and asset information on the FAFSA. This is the only scenario where the form requires both divorced parents' details.

If you are unsure which parent provided more support, gather recent bank statements, mortgage or rent records, and utility bills from both households. These documents show who paid for the student's day-to-day living costs.

The custodial parent and their current spouse

The parent you report on the FAFSA is called the custodial parent. If that parent has remarried or is in a legal domestic partnership, their current spouse's income and assets must also be reported on the form — even if the spouse is not the student's biological parent and did not support the student.

This rule applies whether the custodial parent's new spouse adopted the student or not. The FAFSA treats a stepparent's income as available to help pay for college.

If the custodial parent is not married or in a domestic partnership, you report only that parent's income and assets.

What you need from each parent

For the parent (or parents) you report on the FAFSA, you will need their completed 2023 federal tax return (if submitting in 2024-25) or the most recent tax return available. You also need their Social Security number, date of birth, and state of legal residence.

If a parent did not file taxes, you will need to report their income from W-2 forms, 1099 forms, or other income documents. The FAFSA will ask you to enter the income figure even if no tax return was filed.

You do not need to submit copies of tax returns or documents with the FAFSA itself. However, keep them available in case the school's financial aid office asks to see them later.

When a parent refuses to provide information

If the custodial parent refuses to provide their financial information, you cannot submit the FAFSA without it — the form will not process. If the non-custodial parent (the one not reported on the FAFSA) refuses to provide information, that does not block the form, because their information is not required.

If the custodial parent is truly unavailable — for example, deceased, incarcerated, or completely out of contact — contact the school's financial aid office. Some schools have procedures for students in this situation, though options are limited.

If you and the custodial parent are in conflict over providing information, the school's financial aid office may be able to mediate or explain why the information is needed for federal aid.

How remarriage changes the picture

If the custodial parent remarries after the student turns 18, the new spouse's income still counts on the FAFSA. The marriage date does not matter — only whether the custodial parent is married at the time the FAFSA is submitted.

If the non-custodial parent remarries, their new spouse's income does not appear on the FAFSA, because the non-custodial parent's information is not being reported at all.

If custody changes — for example, the student moves in with the other parent — the FAFSA for the next year will ask about the new living arrangement. The parent with whom the student now lives more will become the custodial parent for that year's form.

Frequently Asked Questions

Do I have to report my non-custodial parent's income on the FAFSA?

No. The FAFSA requires only the custodial parent's income — the parent the student lived with more than half the time in the past 12 months. The non-custodial parent's information is not part of the form. Some schools use a separate form called the CSS Profile that does ask for non-custodial parent information, but that is a different document.

What if my parents split custody exactly 50-50?

Report the parent who provided more financial support during the past 12 months. If both provided equal support, you will need both parents' income and asset information on the FAFSA. Gather documentation like mortgage statements, utility bills, and bank records showing who paid for housing and living expenses.

My custodial parent just got married. Do I need my stepparent's income?

Yes. If your custodial parent is married or in a legal domestic partnership at the time you submit the FAFSA, your stepparent's income and assets must be reported on the form. This applies even if the marriage happened recently or if your stepparent did not help support you.

Can I submit the FAFSA if my custodial parent refuses to give me their tax information?

No. The form will not process without the custodial parent's income information. If the custodial parent is unwilling to provide it, contact your school's financial aid office to discuss your situation. If the non-custodial parent refuses, that does not block the form, since their information is not required.

Does my parent's new spouse's income count even if they don't help pay for college?

Yes. If your custodial parent is married or in a domestic partnership, the spouse's income counts on the FAFSA regardless of whether they contribute to your college costs. The form treats all household income as potentially available for education expenses.
