This is a word that invites Spanish people to make a mistake. Lots of people would say "benefits" but that is wrong.
In English we use "benefits" to talk about the potential positive elements connected with a particular person, project or acquisition. If you want to talk about "beneficios" in English you need to say "profit".
For example: Our "profit" this year is great. Notice that we use it in the singular form rather than plural.
I hope that helps!
