Tax Returns

you should keep a log of mileage to claim.

once you claim mileage you are not allowed to claim running costs (tyres tubes etc) on top of that.

I did this back in the days of being self employed and it worked out much better to claim mileage than anything else.

Just wondering, was your log of mileage backed by any hard evidence (photos of the meter readings I suppose?)?
What did your accountant (if you had one) think of it?
