How to Complete Your FAFSA
The FAFSA is a form you fill out online at fafsa.gov — not through your school, not through a loan company, and not through a third-party website. You create an account, answer questions about your income and family situation, and submit. The federal government uses your answers to calculate how much federal aid your school can offer you. The whole process takes 20 to 40 minutes if you have your documents ready.
You do not need to be a U.S. citizen to complete the FAFSA, but you do need a Social Security number or an Individual Taxpayer Identification Number (ITIN). If you are undocumented, you cannot file the federal FAFSA, but some states run their own aid forms — check your state's higher education agency website.
The form opens each year on October 1 and closes on June 30 of the following year. Schools often give out aid on a first-come, first-served basis, so filing earlier in the window increases your chances of receiving the full amount your school has available.
Key Takeaways
- You file the FAFSA at fafsa.gov using your Social Security number or ITIN, not through your school or a third-party site.
- You will need tax information from the previous year, your parents' tax information if you are a dependent, and your school codes — gather these before you start.
- The form takes 20 to 40 minutes to complete and opens October 1 each year, closing June 30 the following year.
- After you submit, your school receives your information and sends you a financial aid offer within a few weeks to a few months.
- Filing early in the October-to-June window increases your chances of receiving the full amount of aid your school has available.
What Documents You Need Before You Start
Gather these items before you log into fafsa.gov. Having them ready cuts your completion time in half and prevents you from losing your progress halfway through.
You need your own Social Security number or ITIN, your date of birth, and your driver's license or state ID number (if you have one). You also need your parents' Social Security numbers if you are a dependent — the form will ask whether you are dependent or independent, and most students under 24 are considered dependent regardless of whether your parents pay for school.
Bring your most recent tax return and your parents' most recent tax return. If you filed taxes, bring your 1040 form and any schedules. If your parents filed, bring theirs. If neither you nor your parents filed taxes but you had income, bring W-2 forms or other proof of earnings. The form asks for income from the previous calendar year — so if you are filing in October 2024, you will report 2023 income.
You also need the school codes for every college or university you want to attend. Find these at fafsa.gov itself — there is a school search tool. Write down the codes before you start, because you will enter them during the form and the form will not let you proceed without them.
Creating Your Account and Signing In
Go to fafsa.gov and select "Create an Account" or "Sign In." You will create a login using your email address and a password. The system will ask you to verify your email by clicking a link sent to your inbox.
If you are a dependent student, you will also need your parent or guardian to create their own account and sign the form electronically. They do not need to fill out the form — you do that — but they will need to log in and provide their signature at the end. This is called the parent signature requirement. If your parents are divorced or separated, only one parent needs to sign, usually the one who claims you as a dependent on their taxes.
If you are an independent student (usually 24 or older, married, a graduate student, or a veteran), you sign the form yourself and do not need a parent signature.
Filling Out the Form Section by Section
The FAFSA is divided into sections. You can save your progress and return later — the form will hold your answers for up to 10 days of inactivity, then you will need to log back in.
The first section asks for your personal information: name, date of birth, address, phone number, and email. Answer these exactly as they appear on your Social Security card or ITIN letter.
The next section asks about your citizenship and residency. You will confirm you are a U.S. citizen, permanent resident, or other may be able to access non-citizen. You will also enter your state of residency, which determines whether you can receive state aid.
Then comes the income section. You will enter your own income from the previous year, your parents' income if you are a dependent, and information about untaxed income (like Social Security benefits, child support, or military housing allowances). Use your tax return to fill this in. If you did not file taxes, enter zero and move on.
The form also asks about assets — savings accounts, investments, real estate other than your home. Report what you actually own. The form uses income and assets together to calculate your Expected Family Contribution (EFC), which is the amount the government thinks your family can pay toward college.
At the end, you will list the school codes for the colleges you want to attend. You can add up to 10 schools during the initial submission and add more later if needed.
Submitting and What Happens Next
Once you have filled in all required fields, you will review your answers. Check that names, dates, and numbers match your documents exactly — mismatches can delay processing.
If you are a dependent, your parent or guardian will receive an email asking them to sign the form electronically. They log into their own account, review the information, and click to sign. The form cannot be submitted until they do.
After you and your parent (if required) have signed, you submit the form. You will see a confirmation screen with a submission date and time. Save or print this confirmation — you may need it later.
The federal government processes your form and sends a Student Aid Report (SAR) to your email within a few days to a few weeks. The SAR shows the information you reported and your EFC. Your school receives this information automatically and uses it to build your financial aid offer.
Your school will send you a financial aid offer (sometimes called an award letter) within a few weeks to a few months. This letter shows how much federal aid you can receive, what type (grants, loans, work-study), and what you still owe. You do not have to accept the full amount — you can decline loans or reduce your aid if you want.
Common Mistakes That Slow Down Processing
Mismatched names are the most common problem. If your name on the FAFSA does not match your Social Security card or ITIN letter exactly — including middle names, hyphens, or spelling — the government will flag it and delay processing. Use the exact legal name from your official document.
Entering the wrong school codes is another frequent error. Double-check the code before you enter it. If you enter the wrong code, your information goes to the wrong school and you will have to contact the school and the FAFSA processor to fix it.
Reporting income incorrectly — either too high or too low — can change your aid amount significantly. Use your tax return as your source. If you did not file taxes, enter zero, not an estimate.
Forgetting to have your parent sign (if you are a dependent) is a processing blocker. The form will not submit without the parent signature. If your parent does not sign within 10 days, you will need to log back in and request the signature again.
If You Need to Make Changes After Submitting
You can log back into fafsa.gov anytime and make changes to your submitted form. Schools will receive an updated version. If you change your income, assets, or school list, update it as soon as you know — do not wait.
If you submitted the form but realize you made a mistake with your name, Social Security number, or parent information, contact the Federal Student Aid office at 1-800-4-FED-AID (1-800-433-3243). They can correct certain information without you resubmitting.
If your financial situation changes after you submit — you lose a job, your parents' income drops, or you have an unusual expense — contact your school's financial aid office. They can sometimes adjust your aid based on a special circumstance, even if the FAFSA itself does not change.
Frequently Asked Questions
Do I have to use fafsa.gov or can I use a different website?
You must use fafsa.gov. It is the only official FAFSA website run by the federal government. Other websites that claim to help you file the FAFSA are not official and may charge fees or collect your information for other purposes. Go directly to fafsa.gov.
What if my parents refuse to sign or I cannot contact them?
If you are a dependent and your parent will not sign, you cannot submit the FAFSA. However, you may be able to declare yourself independent if you are homeless, in foster care, a ward of the court, or have other documented circumstances. Contact your school's financial aid office to discuss your situation — they can sometimes override the dependency requirement.
How long does it take to hear back after I submit?
The federal government sends your Student Aid Report within a few days to a few weeks. Your school then sends a financial aid offer within a few weeks to a few months, depending on how busy they are. Schools that process aid early in the year (October through December) usually respond faster than those processing in spring.
Can I file the FAFSA on my phone or tablet?
Yes, fafsa.gov works on mobile devices. However, the form is easier to complete on a computer or laptop because you will be switching between the form and your tax documents. If you use a phone, have your documents open in another app or printed nearby.
What if I do not know my parents' Social Security numbers?
You need your parents' Social Security numbers to complete the FAFSA if you are a dependent. Ask your parents directly. If they do not have Social Security numbers (for example, if they are undocumented), contact your school's financial aid office — some schools have workarounds, though your aid options may be limited.
