More information
As an example, if your vehicle maintenance costs p.a. is £400 – if this is totally used for the business, claim the whole sum. If usage is a mix of business/personal then the percentage needs to be worked out. We have provided a simple chart which gives you the percentage to use based upon your business mileage:
Total Year
10.000 miles
100%
£400 (total expenditure)
Business miles
6000 miles
60 %
£240 (business expenditure)
Personal miles
4000 miles
40 %
not allowed
Let us save you the hassle of working on these time-consuming calculations! By using SimpleTax just provide us with the total figure, personal use % and we will do the rest. If your business mileage is high then we may advise you to go for the standard mileage rates rather than the capital expenditure option (expenses inc. fuel/servicing).
You will need to record all of your business miles so that you know how to calculate the percentages for private usage at the end of the financial year. Provided you do this, then you will not need to record your running or repair costs.
Note: If you have used flat rates for a vehicle (mileage allowance), you must continue for as long as you use that vehicle for the business. The same, if you have already claimed capital allowances for a vehicle, you cannot use the mileage rate for it.
