Mileage

Kev works out how far you drove and what you can claim at HMRC rates. You tap once when you set off and once when you arrive.

Before your first journey

Add your vehicle in Settings > Mileage. Pick the type (car or van, motorbike, or bicycle), because HMRC pays a different rate for each.

Bicycles: HMRC's 20p a mile is the rate employers can pay employees. If you're self-employed, simplified expenses has no bicycle rate, so check with your accountant before claiming bike miles on your tax return.

On the free plan you have one vehicle. If you add a new one, it takes over from the old one, and your old journeys stay as they were. Kev Pro lets you keep as many vehicles as you like and pick one each time.

Track a journey

1. Open the Mileage tab.
2. Tap Start Journey. Your phone asks to share your location: say Allow.
3. Drive. You can close Kev or lock your phone.
4. When you arrive, open Mileage and tap Finish journey.
5. Kev asks what kind of trip it was:
   • Work trip: business miles you can claim.
   • Off the clock: personal, nothing to claim.

Kev saves the miles, the addresses and the amount you can claim.

Good to know

• Kev only checks where you are when you tap start and stop. It does not follow you around.
• The distance is the normal driving route between the two places, not every turn you took.
• If the map service is down when you finish, Kev still saves the journey, measured in a straight line. The journey says so, and the real road distance was probably a bit longer.
• Only one journey can be running at a time.
• No signal when you tap start or finish? Kev keeps the time you tapped and saves the journey once signal is back. See Poor signal on site.
• Once you've said whether a trip was work or personal, it's locked in.

Add a journey you forgot to track

Forgot to tap Start, lost signal, or want to add last week's trips? Add them by hand.

1. Open Mileage and tap Forgot to tap Start? Add a journey by hand. It's also on Mileage history as Add a journey.
2. Pick the date, then type where you started and finished.
3. Put a postcode in both places and tap Work it out, and Kev fills in the road distance. You can change it, or type the miles yourself.
4. Say what the trip was for. It goes on your mileage report.
5. Tick Add the return trip too if you drove back the same way.
6. Tap Save journey. Kev works out the claim the same way as a tracked journey.

On a saved work journey you'll also find Add the return trip and Repeat this journey, which fill the form in for you.

Same run again? Log it in one tap. On Mileage, Kev lists the work runs you make most, like the merchant or a long job. Tap Log today and it's saved for today with the same miles, places and reason. Tap Change first if you need a different date or distance. The same list is at the top of Add by hand.

Saved places: give the places you drive to most a name, like Home, Merchant or Big job. When you add a journey, tap the name under From or To instead of typing the address. To save one, type the address and tap Save this place for next time, or add them in Settings > Mileage > Saved places, where you can also remove them. Saved places show by name in your regular trips. You can save up to 20, free.

To count a work journey towards a job, pick the job in the Job box on the journey's page. See Jobs.

Good to know

• Journeys added by hand are always work trips.
• Kev marks them "Added by hand" in your records.
• You can add journeys back to 6 April 2025, the start of the earliest tax year Kev has HMRC rates for.

Fix or delete a journey

Open the journey (tap it in History), then Edit or delete journey. You can change the date, where it started and finished, the miles, what it was for, and whether it was business or personal. Kev works out the claim again when you save, along with any later journeys that tax year (the rate drops after 10,000 business miles, so one change can move the others).

To get rid of it, tap Delete journey at the bottom. Kev asks first.

How the claim is worked out

Kev uses the official HMRC mileage rates for the tax year the journey ended in (tax years run 6 April to 5 April). Cars and vans get a higher rate for the first 10,000 business miles in a tax year and a lower rate after that. Kev keeps count for you and switches over at the right point. It counts in date order, so if you sort an older trip after newer ones, Kev works the newer trips out again where the switch-over point has moved.

HMRC sets new rates each April. If you log a trip in a new tax year before Kev has the new rates, Kev uses last year's rates for now and says so on the journey, under where the rate is shown.

Your own rate

If your employer pays you a set amount per mile, you can use that instead:

1. Go to Settings > Mileage.
2. Under your vehicle, tap Mileage rate: HMRC rates.
3. Choose My own rate, enter the pence per mile (for example 45), and tap Save rate.

Journeys you sort after that use your rate, and show "Your own rate" where the rate is shown. Journeys you've already sorted keep the rate they had. To go back, choose HMRC rates and save. If you're self-employed, stick with HMRC rates: they're what simplified expenses use.

Commute deduction

HMRC doesn't let you claim your normal commute. Tick Deduct my normal commute in Settings > Mileage and enter how far your usual commute is. Kev then asks Where are you starting? and Where have you finished? (Home or Job site). When a work trip starts or ends at home, Kev takes your commute off before working out the claim.

Reports

Tap Reports on the Mileage tab to see your journeys and total claim for a date range, and Download CSV to send to your accountant.

Kev Pro adds totals per vehicle and per month, and any special export format your employer or accountant uses.
