Hertz's reservation system significantly overestimates the taxes due on points rentals (and other free-day rentals).
When you book with points, they effectively adjust your base rate down to $0, and if the tax rate is 30%, you'll end up paying 30% of $0, or $0. The only thing you'll actually pay is the fixed fees that aren't a percentage of anything (and the percentage-based taxes on those fixed fees, which are very small, of course).
The reservation system doesn't know this, so it prices the reservation out as if you'll pay full taxes on the rate. That can safely be ignored.
