FAFSA family size blank/missing - correction needed or auto-populated?
Completely confused about my 2025-2026 FAFSA application - the family size field is showing up as blank after submission. I've read two contradicting things online: 1) that I need to submit a correction to fill it in, or 2) that it should auto-populate if I transferred my tax info through the IRS Data Retrieval Tool. My SAI calculation seems weird, and I'm worried this blank field is causing issues. Has anyone dealt with this specific problem? What's the actual correct procedure here? I don't want to mess up my financial aid by doing the wrong thing!

Family size is NOT automatically populated from your tax information, even when using the IRS Data Retrieval Tool. The system has no way of knowing who you actually support financially just from your tax return. You definitely need to submit a correction to add this information. Missing family size can significantly impact your SAI calculation, usually making it higher than it should be (which means less aid).

•Thank you! I'll submit a correction right away. Do you know how long it typically takes for the SAI to recalculate after submitting the correction? I'm on a deadline for my school's institutional aid application.

•That's reassuring to hear it's not just me. Did your brother's SAI change a lot after he fixed it?

This is one of the most common issues with the new FAFSA system. Family size must be manually entered - it will never auto-populate from tax information, regardless of what some websites claim. The IRS Data Retrieval Tool only imports income and tax data, not household information. Here's the correct process for fixing it: 1. Log into studentaid.gov 2. Select "FAFSA Correction" 3. Navigate to the Household Information section 4. Enter your family size (include yourself, your parents if dependent, and anyone they financially support) 5. Submit the correction Your SAI should recalculate within 3-5 days after submitting the correction. If you're on a deadline, contact your school's financial aid office directly - they can often make adjustments on their end while waiting for the official correction.

•This is super helpful! I think I messed up my family size when I submitted my FAFSA. Is it true that adding dependents in your household makes your SAI go down?

I had this EXACT same problem and it was a complete nightmare. I called the Federal Student Aid helpline like 12 TIMES and couldn't get through to anyone!!! I kept getting disconnected or put on eternal hold. When I finally reached someone they told me it was definitely NOT auto-populated and I needed to submit a correction. My SAI dropped by $4,200 after fixing it which meant I qualified for way more aid. Don't wait - fix it ASAP!!!

•I had the same experience trying to call FSA! After trying for days with no luck, I used Claimyr.com to get through to an agent in about 15 minutes. They have this service where they wait on hold for you and call when an agent is ready. Saved me hours of frustration. There's a demo video at https://youtu.be/TbC8dZQWYNQ showing how it works. The agent confirmed family size needs manual correction and they helped me submit it right over the phone.

•Your school gave you incorrect information. Household size for FAFSA purposes includes: - Yourself (the student) - Your parents (if you're a dependent student) - Your parents' other children if they provide more than half their support - Other people who live with your parents AND receive more than half their support from them This isn't necessarily the same as who's listed on a tax return. Some people may be in your FAFSA household size but not on the tax return, or vice versa.

My daughter had this issue too and we fixed it through the correction process. Weird thing is her friend swears hers WAS auto-populated when she used the IRS tool... so maybe it's inconsistent? Either way, def submit the correction to be safe.

•It's definitely not auto-populated. Her friend is likely mistaken - they probably manually entered it and forgot, or someone else helping them with the FAFSA entered it without telling them. The FAFSA system simply doesn't have access to determine your true household size from tax data.

Thanks everyone for the helpful responses! I submitted the correction this morning and included myself, my parents, and my younger sister who they support. Hoping this brings my SAI down to qualify for more aid. I'll update once it recalculates in case anyone else runs into this same issue.

Just wanted to add that you can also check if your correction went through by looking at your Student Aid Report (SAR) - it should show the updated family size information once processed. Also, make sure when you're counting family size that you don't accidentally include grandparents or other relatives who might live with you but don't receive more than half their support from your parents. I made that mistake initially and had to submit another correction. The whole process is confusing but once you get it right, your SAI calculation will be much more accurate!

•This is really helpful advice about checking the SAR! I didn't know about the grandparents thing - that could have been a costly mistake. Quick question: when you say "more than half their support," does that include things like health insurance and utilities, or just direct expenses like food and housing? I want to make sure I'm counting correctly before I submit my correction.
