Mileage is not the place to roughly estimate

For rural businesses, mobile teams, site-based trades and owners constantly on the road, mileage claims are one area where small mistakes can quietly become expensive.

It’s surprisingly easy to underclaim, overclaim, or simply end up with records that don’t stand up to scrutiny. Whether you’re travelling between farms, construction sites, suppliers, workshops, client meetings, towns or cities, every mile counts.

Many business owners assume mileage is a straightforward administrative task. In reality, it’s one of the most commonly misunderstood areas of business expenses. Staff using their own vehicles for work still need to be reimbursed correctly, and the approved mileage allowance rates remain an important benchmark for both employers and employees.

The rules don’t stand still either. If your business operates electric company cars, the advisory fuel rates changed again from 1 March, making it even more important to ensure claims and reimbursements are based on current guidance.

A few miles missed here and there may not seem significant, but over weeks, months and across multiple employees, those errors can quickly add up. Equally, overclaiming can create unnecessary tax and compliance risks that are easily avoided with the right systems and records in place.

Mileage tracking isn’t complicated. The principles are simple. But getting it right can make a noticeable difference to your costs, compliance and confidence if HMRC ever comes asking questions.

It looks basic. It is basic.

But it still matters.
