Are you looking at a paper ticket? Does the amount listed next to "fare" have a 2-letter designator next to it? If so, it's also a tax. The problem is that the standard ARC ticket stock doesn't have enough lines to indicate all the different kinds of taxes and fees there are today, so they sometimes have to print a tax amount on the "fare" line. You should see an amount of $0 above this, with no designator next to it. That is the base fare.
