Adjusted Net Income & Personal Salary Sacrifice Electric Vehicle

I have a question on the impact of a salary sacrifice electric car to the adjusted net income. Where no car allowance or company car is in place it is possible through Tusker to take a personal vehicle and sacrifice salary before tax to pay for it. As i understand it, in this scenario the recued salary is what payslips / P60 will show and so this will reduce the adjusted net income, albeit the BIK for the vehicle will need to be added back on. Is this understanding correct? This is how Tusker describe it: HMRC view this arrangement as an employment law matter rather than a tax law matter, as you are free to agree a change in your remuneration with your employer. Entering into this arrangement is in essence the same as agreeing to a reduction in your salary. HMRC do request that the change in salary is "permanent", meaning that any change must be for a minimum 12 month period. In addition you must also agree to sacrifice your salary before you take delivery of your car. As the car is made available to you by your employer, and is viewed as a company car by HMRC, it is classed as a Benefit in Kind (BiK).

Hi,
 

You are correct, the lower pay is reported to HMRC and the value of a BIK is added on .

Thank you.
