Business mileage is the distance you travel by car, van, or motorcycle for work purposes—excluding your regular commute to the office. If you’re self-employed or run a business, you can claim tax relief for these journeys using HMRC’s approved mileage rates or by tracking actual vehicle costs.
Good record-keeping is key: note your start point, destination, purpose of trip, and miles traveled. The more accurate your records, the more you can claim—without raising HMRC’s eyebrows.
