<human>: Summarize the given text in a few sentences.

I'm 21 years old and about to graduate college. My parents have taken out a large sum of federal PLUS loans for my education, and I would like to give them some money that I made over the summer to help pay off these loans. The amount in question is about $5,000, and I know that my parents are able to receive paid interest exemption on their federal loan. Is there any way for me to give my parents this amount without having to include it in my personal income tax return, and are there any other rules I need to keep in mind for my parents and myself when filling taxes?
<bot>: How can my family and I pay the least amount of taxes on $5,000 that will be used towards my education?
