I'm fortunate to get a car allowance as a perk. Previously I've taken the allowance as cash and bought my own car.

The company is offering zero emission electric cars at the moment. I'm struggling to follow the guidance being not very familiar with it.

If I went with a £300 pcm car via salary sacrifice with a P11D of £30k, how much would this cost me nett as a higher rate tax payer? Am I right that BIK is 1%?

I'm a bit confused, so anyone else who has done this for a zero emission electric car, and can explain the maths and the nett amount, then that would be good.

Thanks in advance.
