Changing Basis For Car Expenses

martindow

For convenience I have always used the 45p/ mile method for business mileage for a car used for both business and private use.

I am sure that I would be much better off working out the actual car expenses and apportioning it to get a figure for business use. Can I just decide from a certain date to change or is it more complicated than that?

See https://www.gov.uk/simpler-income-tax-simplified-expenses/vehicles-

"You do not have to use flat rates for all your vehicles. Once you use the flat rates for a vehicle, you must continue to do so as long as you use that vehicle for your business."

Thanks Jeremy.  I suspected as much.  A bit of a shame with petrol getting more expensive and a car that seems to be needing more repairs, changing would have been benficial.
