To "raise eyebrows" means to cause one to feel surprised (usually in a negative, disapproving way). The speaker has used this idiomatic expression to state that the extremely low taxes paid by corporations in America is disapproved of by some politicians. Ex: The government's handling of the pandemic has raised eyebrows. Ex: The rude behavior of the customer in the store raised a few eyebrows.
