FAFSA Family Size Determination

I’m interested in the updated family size determination for 25-26 which uses 2023 tax info. Our AGI will be close to the Maximum Pell grant level (175% of fed poverty for married couple). But, I’m not sure how they will calculate family size. Is it based on 2023 tax year dependants? Or on family size when filling out the FAFSA? We have an older child that will have graduated college by the time we fill out the FAFSA for 25-26, but will still be a college student and tax dependent for 2023. Whether he counts in the family size or not determines what 175% of AGI level is used.

I answered under your other post on a different thread. It looks like he should count for 2025-26 if he is listed on the tax return in 2023 … but Department of Education could update that guidance.
