What this guide covers
Send a message like "32 miles to client site" and the claim is calculated at HMRC's approved rates (45p for the first 10,000 business miles each tax year, then 25p; motorcycles 24p; bicycles 20p) and recorded as a travel expense.
1. Send the journey as a message
Message your linked WhatsApp number with the miles and a short description, for example "32 miles to client site" or "12.5 miles supplier visit". Do not include a £ amount — a message with a £ amount is treated as a normal expense instead.
See WhatsApp capture basics2. Mention the vehicle if it is not a car
Car or van journeys use the 45p/25p rates automatically. Say "motorbike" for the 24p rate or "cycled"/"bike" for the 20p rate — for example "18 miles on the motorbike to site".
See command reference3. Check the confirmation
The reply shows the rate breakdown, the amount recorded, and your running year-to-date business miles. Once you pass 10,000 miles in a tax year, car and van claims switch to 25p automatically — including mid-claim, where a single journey is split across both rates.
Open Activity4. Review it like any other expense
The claim is recorded as a confirmed travel expense and feeds your tax estimate and quarterly figures immediately. You can edit or delete it in Activity like any other transaction.
Record in ActivityBefore you move on
- The message contains miles and a description, with no £ amount
- The vehicle was mentioned when it is not a car or van
- The confirmation breakdown and YTD miles look right
- Only business journeys are claimed (commuting does not count)
