Salary Sacrifice Car and Tax

Black_Eyeliner

Hope this is in the right area of the forum.

I lease a car from my employer through a salary sacrifice scheme. My tax code is adjusted and car benefit deducted from my personal allowance. I have noticed, however, that the car benefit deducted from my personal allowance has increased year on year; £5050 in 2017/18, £5555 in 2018/19, and £6312 in 2019/20.

I am driving the exact same car as I was in 2017. Can anyone explain why HMRC think I am getting more benefit from the car now than in previous years?

Thanks.

I believe its to account for your vehicle becoming less fuel efficient with age (compared to new vehicles coming on the market), not because they think you're getting more benefit.
