Tax should have been included in the valuation presented to you by the at-fault insurance carrier. They owe you vehicluar sales tax, if they didn't include it in the valuation you need to make sure they throw that into the figures. Most do not add in the cost for the tag transfer and title work. Remember they are paying the value of the vehicle...tag & title have no bearing on the value of a car. However, some companies will reimburse you this cost if asked.

How is the process going so far? Have the presented a value yet? If so, who are they using to value the vehicle? If you need any help, let me know!
