How does the full-time student part work? I spent one semester as a full-time and another as not so im wondering how this changes my filing.

The IRS states that if you were a full-time student for at least 5 months, then you count as a full-time student for the whole year. This means that since you were full-time for a semester, you were a full-time student in 2025. 

The way this impacts your filing is that if you're under 24, your parents can still claim you as a dependent. You are also eligible for educational tax credits, including the American Opportunity Tax Credit that requires at least half-time status for one semester.

Being a fulltime student for a semester usually meets the requirement to be considered a full time (FT) student for the year. But, there is a technicality that must be met. You must have been an FT student for parts of 5 calendar months.  A semester from anytime in January (even Jan 31) to anytime in May (even May 1) meets that requirement. A semester from Jan-Apr or Sep-Dec does not.

Half time or more qualifies for the tuition credit.

Full time is more about dependency.  

There are two types of dependents, "Qualifying Children"(QC) and Other ("Qualifying Relative" in IRS parlance even though they don't have to actually be related). There is no income limit for a QC but there is an age limit, student status, a relationship test and residence test.

A child of a taxpayer can still be a “Qualifying Child” (QC) dependent, regardless of his/her income, if:

1. He is under age 19, or under 24 if a full time student for at least 5 months of the year, or is totally & permanently disabled
2. He did not provide more than 1/2 his own support. Scholarships are excluded from the support calculation
3. He lived with the parent (including temporary absences such as away at school) for more than half the year
