Job offer, negotiations and Car Allowance

[Lostprophet]

Hi Folks,

I have been an offer by a company. It's slightly less than I expected in net pay however they have offered £6k car allowance which makes it a reasonable offer. I am not up to speed, no pun intended, on how car allowance is taxed. Could any one provide some insight please? i'm a higher rate tax payer.

The consultant managing the negotiations is reluctant to push the base any higher as he says the package in total is really good. He said it might put a bitter taste in the mouth of the employers.

Any advice would be welcomed.

Thanks,
LP
