FAFSA for divorced parents: Which parent reports income?

Introduction

When parents are divorced, the FAFSA requires financial information from only one: the custodial parent, which is the parent the student lived with most in the past 12 months. Choosing the wrong parent can delay aid and increase out-of-pocket costs for families—and create avoidable debt for students.

Navigating this rule can be confusing, especially with complex custody arrangements or changing financial situations. This guide provides a clear path forward, explaining how to correctly identify the custodial parent using a step-by-step framework. You’ll also learn what income and assets to report, how to handle special circumstances like remarriage, and how to avoid common mistakes that can jeopardize your aid. Finally, we’ll clarify key differences between FAFSA and CSS Profile rules for divorced families.

FAFSA rules for divorced parents: Context at a glance

The Free Application for Federal Student Aid (FAFSA) has a specific and non-negotiable definition of which parent’s information to use in cases of divorce or separation. It’s not based on legal custody agreements or who claims the student as a dependent on their taxes. Instead, the rule is based entirely on residency. According to StudentAid.gov, you must report information for the parent you lived with more during the 12 months ending on the date you file the FAFSA. This parent is referred to as the “custodial parent” for FAFSA purposes.

This means you need to count the number of days spent with each parent over the past year. For example, if you file on October 1, 2024, you would look at the period from October 2, 2023, to October 1, 2024. According to StudentAid.gov, the parent with whom you lived for 183 days or more during that time is the one whose financial information must be reported. It is a common misconception that the parent who provides more financial support or has legal custody is automatically the one to list; this is incorrect for the FAFSA.

Once you identify the custodial parent, you will report their income, assets, and household size on the FAFSA. If that parent has remarried, you must also include your stepparent’s financial information. The non-custodial parent’s financial information is not required on the FAFSA form. The following section provides a step-by-step framework to help you make this determination accurately.

Determining your custodial parent: Step-by-step decision framework

Determining the correct parent to report on the FAFSA follows a clear, sequential process. It’s essential to follow these steps in order, as the primary rule is based on physical residency, not financial support, unless a specific tie-breaker condition is met. Use this framework to identify the custodial parent accurately.

The first and most important step is to count the number of nights the student lived with each parent. You must look at the 365-day period ending on the date you file the FAFSA. According to StudentAid.gov, the parent with whom the student lived for the majority of that time (183 nights or more) is the custodial parent for FAFSA purposes. This is a strict rule; legal custody agreements or which parent claims the student on their taxes are not considered. Keep a simple log or use a calendar to count the days if the living arrangement is complex. Time spent away at boarding school, with friends, or on vacation should be counted as time residing with the parent whose home the student would return to.

In rare cases, a student may have spent an exactly equal amount of time with each parent. Only in this specific situation does a tie-breaker rule come into play. According to StudentAid.gov, if the student lived with each parent for the exact same number of days in the past year, the custodial parent is the one who provided more financial support during that same 12-month period. Financial support is not just child support; it includes:

• Housing (rent or mortgage payments)
• Food and groceries
• Clothing
• Medical and dental care costs, including insurance premiums
• Tuition and school-related expenses
• Car payments and insurance
• Other cash support and gifts

Add up the total support provided by each parent. The one who provided a greater amount is the parent whose information must be on the FAFSA.

Some students may not live with either parent, perhaps residing with grandparents or other relatives, or living on their own. Even in these situations, you must still determine a custodial parent based on the rules above. The FAFSA considers the student’s legal residence to be with a parent unless they meet the criteria for independent student status. The question remains: during the past 12 months, which parent did the student last live with for a longer period, or which provided more support if time was equal? The same residency and tie-breaker logic applies.

Once you have confidently identified the custodial parent using this framework, your next step is to gather all the necessary financial information from that parent (and their spouse, if they are remarried) to report on the FAFSA.

What financial information to report from your custodial parent

Once you’ve identified the custodial parent, the next step is to gather their financial information to report on the FAFSA. A critical rule to remember is that if your custodial parent has remarried, you must include the stepparent’s income and assets on the form, regardless of prenuptial agreements or whether they plan to contribute to college costs. The FAFSA considers the stepparent part of the custodial parent’s household.

The FAFSA requires a comprehensive look at the custodial parent’s (and stepparent’s) financial situation. You will need information from their federal income tax returns, records of untaxed income, and current balances of cash, savings, and checking accounts. You’ll also report the value of investments, such as stocks, bonds, and real estate (other than your primary home). According to StudentAid.gov, under FAFSA Simplification rules effective for the 2024–2025 academic year, the net worth of any family-owned small businesses and farms must also be reported as assets.

The following table outlines what financial information to include and what to exclude:

You must also report the number of people in your custodial parent’s household. This figure directly impacts the calculation of your Student Aid Index (SAI). According to StudentAid.gov, the household size should include:

• The student (yourself)
• The custodial parent
• The stepparent (if the custodial parent is remarried)
• Other children who will receive more than half of their support from the custodial parent (and stepparent) between July 1 of the award year and June 30 of the next.
• Other people who live with and receive more than half of their support from the custodial parent and will continue to do so during the award year.

It’s crucial to report only the information for the custodial parent and their current household. The non-custodial parent’s income and assets are not reported on the FAFSA, which is a key difference from other aid applications like the CSS Profile. However, financial support received from the non-custodial parent, such as child support, is handled differently and has its own specific reporting requirements.

How child support and alimony affect your FAFSA

How child support and alimony are reported on the FAFSA has significantly changed under the FAFSA Simplification Act, a shift that directly impacts a family’s financial aid eligibility. According to StudentAid.gov, as of the 2024–2025 FAFSA, any child support the custodial parent receives is no longer reported as untaxed income. Instead, it is now included as an asset. This is a crucial distinction because assets are assessed at a much lower rate than income in the Student Aid Index (SAI) calculation. According to StudentAid.gov, you must report the total amount of child support received for the last complete calendar year.

This change generally benefits students from families receiving support. By treating these funds as an asset, the FAFSA formula places less weight on them, which can result in a lower SAI and potentially qualify the student for more need-based aid, such as the Pell Grant or subsidized federal loans. Similarly, alimony received by the custodial parent is also reported as an asset, not income. The total value of these payments received over the prior calendar year should be added to the parent’s total assets when filling out the form.

On the other hand, if the custodial parent pays child support or alimony, those payments are not used to reduce their reported income or assets on the FAFSA. The form’s calculations for determining the SAI already account for necessary living expenses based on household size and income levels, so there is no separate deduction for support paid out. Correctly reporting these specific financial details is essential, but they are just one piece of the puzzle, as other unique family situations can also require special handling.

Special circumstances and how to handle them

Divorced and separated families often face situations that don’t fit neatly into the standard FAFSA guidelines. If your family’s circumstances are complex, it’s crucial to know how to proceed to avoid delays or errors in your financial aid application. The key is often to communicate directly with a college’s financial aid office.

A common point of confusion arises when parents have recently divorced or separated. The FAFSA requires tax information from two years prior, a time when your parents may have been married and filed taxes jointly. However, you must report your custodial parent’s marital status as of the day you file the FAFSA. If their current income is now significantly lower than what was reported on that joint tax return, you should contact the financial aid office at each college you’re considering. You can request a professional judgment review to have your financial aid eligibility reassessed based on the new, lower household income.

In some difficult situations, the custodial parent may refuse to provide their financial information for the FAFSA. It is important to understand that you cannot simply use the non-custodial parent’s information instead. If you find yourself in this position, you must contact the financial aid office and explain the circumstances. A Financial Aid Administrator (FAA) may determine that you are eligible for a dependency override, which would allow you to file the FAFSA as an independent student. This is granted on a case-by-case basis and requires documentation of your inability to obtain the parent’s information.

The FAFSA rules are the same for parents who never married as they are for those who are divorced. The parent who should complete the FAFSA is the one the student lived with more during the 12 months prior to filing. If the student lived with each parent for an equal amount of time, the parent who provided more financial support is responsible for filling out the FAFSA. The term “custodial parent” applies based on these residency and support rules, not on a legal marriage or divorce decree.

Even if a student lives with another relative, like a grandparent, or on their own, they are generally still considered a dependent student for FAFSA purposes. In this case, you must still determine which parent is the custodial parent based on where you last lived the longest or who last provided more financial support. Only students who meet the specific federal criteria can file for independent student status. Understanding these nuances is the first step to ensuring your FAFSA is accurate, which helps you avoid common filing errors.

Common FAFSA mistakes divorced families make

Navigating the FAFSA with a divorced family structure can feel complex, but avoiding a few common and fixable mistakes can make the process much smoother. Catching these errors ahead of time helps prevent processing delays and ensures you receive the maximum financial aid for which you are eligible.

The most frequent error is choosing the parent based on a legal custody agreement or who claims the student as a dependent on their taxes. This is incorrect for FAFSA purposes.

• How to fix it: Always use the residency rule outlined in the step-by-step framework earlier in this guide. The parent the student lived with for the majority of the last 12 months is the custodial parent for the FAFSA, regardless of other arrangements.

If the custodial parent has remarried, it’s a common mistake to omit the stepparent’s financial information, especially if there’s a prenuptial agreement or the stepparent doesn’t plan to contribute to college costs.

• How to fix it: The FAFSA requires the stepparent’s income and assets to be reported alongside the custodial parent’s. As explained in the section on financial reporting, they are considered part of the student’s household.

Some families mistakenly believe providing financial information for both parents is more transparent or helpful. However, the FAFSA is specifically designed to exclude the non-custodial parent’s finances.

• How to fix it: Only provide information for the custodial parent and their spouse (if remarried). Adding extra, unrequired information can cause confusion and delays.

Finally, a significant source of error is assuming all financial aid applications follow the same rules. This is particularly true when comparing the FAFSA to the CSS Profile, which often has different requirements for divorced families.

Before exploring private student loans, it’s important to maximize your federal aid options first. Federal loans typically offer protections that private loans do not, such as access to income-driven repayment plans and Public Service Loan Forgiveness (PSLF). If you need to fill a funding gap, private lenders will check your credit history. Many students will need a creditworthy cosigner to qualify. You can check rates with multiple lenders without impacting your credit score, as initial checks are soft credit pulls. A hard credit pull only occurs if you formally apply.

If aid won’t cover everything, compare rates from 8+ lenders—no impact to your credit to prequalify.

FAFSA vs. CSS Profile: Key differences for divorced parents

While the FAFSA has a clear rule excluding the non-custodial parent’s finances, it’s crucial to know that not all financial aid applications work this way. The CSS Profile, an application used by nearly 400 private colleges and scholarship programs to award their own institutional aid, has a significantly different requirement. Unlike the FAFSA, the CSS Profile does require financial information from the non-custodial parent in most cases.

The logic behind this is that these institutions believe both parents have a responsibility to contribute to their child’s education, regardless of their marital status. The non-custodial parent will typically need to complete a separate Noncustodial PROFILE application. In situations where contacting the non-custodial parent is not possible or would be harmful, students can submit a request to waive this requirement, but it requires documentation and is approved on a case-by-case basis. For a complete breakdown of these rules, see our guide to the CSS Profile.

Understanding these key distinctions is vital for families applying to schools that require both forms. With these rules in mind, let’s address some other frequently asked questions about the FAFSA process for divorced parents.

Frequently asked questions

In the rare case of a true 50/50 custody split where the student lived with each parent for the exact same number of days, the tie-breaker rule applies. The custodial parent is the one who provided more financial support over the past 12 months. As detailed in the decision framework above, this includes costs for housing, food, healthcare, and other necessities.

Yes. If your custodial parent has remarried, you must include their spouse’s (your stepparent’s) income and assets on the FAFSA. The federal government considers the stepparent part of the student’s household for financial aid purposes, regardless of any prenuptial agreements. This requirement is covered in the section on reporting financial information.

You must report your custodial parent’s marital status as of the day you file the FAFSA. If their current income is now significantly lower than what was reported on a prior joint tax return, you can contact each college’s financial aid office to request a professional judgment review, as explained in the “Special Circumstances” section.

No. Only one FAFSA form should be filed per student. The application must be completed using only the financial information of the custodial parent (and their spouse, if remarried). Submitting multiple FAFSAs will cause processing errors and significant delays in receiving your financial aid offer.

Yes, in most cases. As mentioned in the previous section, the CSS Profile has different rules than the FAFSA and typically requires financial information from both the custodial and non-custodial parent to determine eligibility for institutional aid from certain private colleges.

Navigating the FAFSA as a divorced family requires careful attention to detail, but you now have the framework to complete the form accurately and confidently. By following the rules correctly, you can ensure you receive the maximum financial aid for which you are eligible. As you move forward, keep these key action items in mind:

• Determine the custodial parent: Use the 12-month residency rule to identify which parent’s information to report, not legal custody or tax filing status.
• Include your stepparent: If your custodial parent has remarried, their spouse’s financial information is required on the FAFSA.
• Exclude the non-custodial parent: Do not report the non-custodial parent’s income or assets on the FAFSA.
• Address special circumstances: If your situation is complex or has recently changed, contact each college’s financial aid office to discuss a professional judgment review.

Always maximize your federal aid options first, as they offer unique protections like income-driven repayment plans and Public Service Loan Forgiveness (PSLF). If a funding gap remains, private student loans can be a solution. Private lenders will assess credit history, and many students need a creditworthy cosigner to qualify. Checking your rates won’t affect your credit score since initial checks use a soft credit pull.
