On what amount should local and state taxes be computed, on the base rental price alone or after having added to it all the rental company-imposed fees? In other words, does one need to pay taxes on the rental fees?
The question is motivated by my last rental, in which, due to a sudden issue, I had to return the car at a different location. I called the rental company and agreed to pay their hefty "one way drop-off fee", which was comparable to the cost of the entire weekly rental. In the final bill, however, an even greater amount was taken from my credit card. When I called customer service, I was told that the amount I was given on the phone was pre-tax and that "of course" I had to be pay state and local taxes on it.
I have two issues with this answer, the first, minor one, is that this should have been explicitly mentioned at the time we agreed on this supplemental contract. The second one is that the concept of having to pay taxes on a fee seems a rather absurd one, even though I guess one could possibly construe the fee as the payment for an additional service that I requested.
Is the rental company correct in its assessment?
EDIT
Not sure if this is the correct way to partially amend a question. I just wanted to add that after reading this very informative article on Autoslash I realized that my description of the "extra charges imposed on the fees" was incorrect as I lumped them all in the local and state taxes bucket, while they were of different nature. In fact, to the 10% of the Los Angeles sales tax, and the 3.5% of the California tourism collection fee the rental agency added also an 11.11% of airport concession fee, which, according to Autoslash, is a "fee not mandated by airport authorities, but it ensures the rental car company gets a slice of revenue while putting the airport’s cut in its own bucket."
To clarify, all the three percentages mentioned above, roughly amounting to 25%, were computed in the rental contract on a basis amount that included the weekly rental cost plus the daily fees imposed by the rental car agency (customer facility charge and vehicle license recovery fee). Then afterwards, in the final bill, all three of them were charged as well on the one-way drop off-fee that I had been quoted. Not a big deal, but the fact that the memory lapse at the time of quoting did not involve just mandated taxes makes it just a couple of tones shadier.
