Driving between clients? You could be owed tax back.
Log your work miles, see how much less than HMRC's 55p rate your employer pays you, and estimate the tax relief you could claim back.
New for 2026 HMRC raised the mileage rate from 45p to 55p a mile on 6 April — the first rise in over 13 years.

How it works
Postcodes and miles between clients. Under a minute a day — with return trips and repeat days in one tap.
We compare what you were paid with HMRC's 55p a mile — and with your contract rate.

Questions carers ask
How much could I get back?
It depends on your miles and what your employer pays. For example, 400 work miles a month paid at 25p is about £24 a month back for a basic-rate taxpayer — around £288 a year. You can usually claim for the previous 4 tax years too.
The 55p rate applies from April 2026 onwards. Claims for earlier tax years (2022–23 to 2025–26) are worked out at HMRC's previous 45p rate.
My employer pays nothing for mileage. Can I still claim?
Yes — and it's often the biggest claim. You can claim tax relief on the full HMRC amount: 55p a mile for your first 10,000 work miles. At 400 miles a month, that's about £44 a month back for a basic-rate taxpayer.
Does the drive from home to my first client count?
Usually, yes. HMRC normally treats each client's home as a temporary workplace, so for most home carers the trip from home to the first client and back from the last one counts as work travel. There are exceptions — if you always drive to the same client, for example — so check GOV.UK if you're unsure.
Will claiming get me in trouble with my employer?
No. The claim is between you and HMRC — you don't need your employer's permission. If you're owed money under your contract, that's a separate conversation you can choose to have.
Is it really free?
Yes. There's no sign-up and no card details.
Where is my information kept?
Only on your phone. Nothing is sent to us. Use the backup option in Settings so you don't lose it if you change phones.
Can I check if my employer has underpaid me?
Yes. If your contract promises a mileage rate, CareMiles works out the rate you were really paid from your payslip and shows any difference.
Is this tax advice?
No. CareMiles gives estimates to help you claim. Always check GOV.UK or a qualified adviser before making a claim.

This is separate from your tax claim — ask your employer for it. Check what your contract covers (some don't pay for the first and last trip of the day). If they pay it, your tax back goes down a little.

At a glance
10,000-mile limit
HMRC allows 55p a mile for your first 10,000 work miles each tax year, then 25p. Before April 2026 the rate was 45p, so earlier tax years use 45p.

💡 Where do I find my real miles?
- Your rotas or schedules — which clients you visited each day.
- Your care company's app — some keep a history of your visits.
- Google Maps Timeline — if location history was switched on.
- Then look up the driving distance between the postcodes on a map and add them up.
⚠️ Don't just copy the miles from your payslip if your employer doesn't pay for every journey. HMRC may ask how you worked out your miles, so keep your rotas.
Months with logged journeys show them under the month name. Miles you add here are on top of those.
