Claiming travel expenses correctly can reduce your tax bill and ensure HMRC compliance. This guide explains the rules for business travel, what expenses are allowable, and how to calculate claims for your UK business.
Experience


HMRC defines business travel as journeys made 'wholly and exclusively' for business purposes. This excludes your regular commute from home to a permanent workplace, which is not claimable.
For limited companies, directors can claim mileage using approved rates, while sole traders include travel expenses in their Self Assessment. Keeping detailed records is essential to prove each journey was for business.

HMRC allows various travel-related costs when incurred for business. Here are the key expenses you can claim, with specific rules and limits:
Business mileage at 45p per mile for the first 10,000 miles (25p thereafter) using your own vehicle.
Public transport fares like trains, buses, or coaches for business journeys, including season tickets if used for business travel.
Taxi or ride-share costs when public transport isn't practical, such as late-night trips or carrying equipment.
Parking fees at business destinations, but not parking fines which are never allowable.
Congestion charges, tolls, and ferry costs directly related to business travel.
Hotel accommodation when staying away overnight for business purposes.
Meals during business travel, but only if incurred as part of the journey (not regular daily lunches).
Air fares for business flights, including checked baggage fees necessary for the trip.
Tube, tram, or metro fares in cities visited for business meetings or events.
Car hire expenses when a vehicle is needed at your destination for business activities.

A common error is claiming for ordinary commuting to your permanent workplace, which HMRC disallows. Also, avoid double-claiming by choosing either mileage rates or actual costs for the same journey, not both.
Maintain detailed logs with dates, destinations, purposes, and miles. If your travel is complex, such as multiple temporary workplaces or overseas trips, consulting with a professional like AA Tax & Accounting can ensure compliance and maximize claims.
