Private EV - milage claim with on road charging costs

I have a private EV (salary sacrifice) which I use for business purposes. I understand I can claim tax relief on 45p per mile as my employer doesn’t refund any milage. They do though refund any on road charging costs (e.g. motorway services) I incur. Do I need to deduct anything they refund from the milage claim or can I claim the charging costs from employer and still claim tax relief on full 45p per mile?

Hi David Carey,

When calculating mileage allowance you would need to deduct any mileage allowance payments made by the employer.

Thank you.

I'm not HMRC but unfortunately the 45p per mile is only available when you are using your own vehicle for business travel. It is not available for company cars (which this is if it is salary sacrifice).
