Recently we have seen examples of HMRC asking to see locum mileage logs and refusing claims without them. So please try to keep a mileage log of all practice related journeys. It is much easier to take out what turns out not to be deductible, than to try to recreate information that wasn’t retained in the first place.
A mileage log can be a notebook kept in the car; a spreadsheet or a phone app that calculates journeys that you can annotate.
What if you have not kept a log?
For home to GP surgeries, it is easy enough to ‘google’ journeys to find the mileage. Visits are much harder if you haven’t retained records. Some surgeries’ computer systems can produce a printout of visits by doctor, from which you can then work out the mileage. This might work for salaried doctors, but the practices are likely to be less enthusiastic hunting out the information for irregular locums.
Don’t forget to include other travel in the course of work – such as for training courses. If they are not local, that can be a noticeable amount. Salaried doctors will not be able to claim it themselves; they will need to try to get reimbursement from the practice.
If the pattern of work has not changed then a sample period might be sufficient but this is only likely to work for salaried doctors’ visits – and if HMRC want to do it by the book, it still may not be enough. Locum work is unlikely to ever be settled enough for a sample period of mileage log to be representative – so doctors in that position need to get into the habit of keeping a regular log.
Self-employed doctors may usually claim a mileage rate similar to salaried GPs, but if their turnover exceeds £81k (for 2014-15) they should claim a proportion of total car running costs.
