Mileage Rate 2026 in Sheffield: Complete Guide for Local Drivers

The mileage rate 2026 for a self-employed driver using the simplified method is 55p a mile for the first 10,000 business miles in the 2026/27 tax year, then 25p a mile after that. If you drive in Sheffield, the rate itself is the easy part. The harder questions are where your 10,000th mile lands, which rate your 2025/26 return uses, and what Sheffield costs sit outside the mileage claim.

This guide is built around those questions. It follows one invented Sheffield driver through a full year, month by month, so you can see exactly when the 55p band runs out. It then covers the Sheffield licensing and Clean Air Zone details, a claim checklist and the mistakes we see most often.

Key takeaways

• The mileage rate 2026 is 55p a mile for the first 10,000 business miles and 25p after that, according to GOV.UK's simplified expenses guidance for vehicles.
• HMRC's policy paper says the increase from 45p is retrospective to 6 April 2026, so it covers the whole 2026/27 tax year rather than only journeys after the announcement.
• The 10,000-mile band is counted across the tax year, so your first miles of the year are the most valuable ones. Where those miles fall in the calendar matters when you plan cash flow.
• Your 2025/26 return, due by 31 January 2027, still uses the old 45p rate, because that year ended on 5 April 2026.
• Sheffield's licence fees and any Clean Air Zone charge are separate decisions. Check with an accountant before you claim them alongside the flat rate.

What is the mileage rate 2026?

The mileage rate 2026 is HMRC's flat rate per business mile for cars and goods vehicles under simplified expenses. For 2026/27 it is 55p for the first 10,000 miles and 25p afterwards. It replaces your actual fuel, insurance, repairs and depreciation costs for that vehicle.

How does the 6 April 2026 change affect a Sheffield driver?

The first-band rate rose from 45p to 55p, and the rate above 10,000 miles stayed at 25p. Because HMRC made the change retrospective to 6 April 2026, you do not split the 2026/27 year into a 45p part and a 55p part. Every business mile up to 10,000 in the year earns 55p.

That point catches people out because the rise was announced in May 2026, weeks after the tax year began. Any mileage tracker, spreadsheet or tax app that you set up in April may still be using 45p. According to HMRC's policy paper on increasing mileage rates, the measure applies to the 2026 to 2027 tax year with effect from 6 April 2026.

The real split is between years, not within one. Miles driven up to 5 April 2026 belong to 2025/26 and use 45p for the first 10,000. Miles from 6 April 2026 belong to 2026/27 and use 55p. Keep the two years in separate columns of your log.

Where does the 10,000-mile band run out?

The 10,000-mile band runs out whenever your cumulative business miles for the tax year pass 10,000. For a full-time Sheffield driver that usually happens by the autumn. Everything after that point earns 25p a mile, so your claim per mile drops by more than half.

Most guides we read stop at the two rates and one annual total. None of the ones we checked show the point in the year where the band runs out, which is what you need for planning. Our worked example below does that.

What does a year of Sheffield mileage look like in practice?

A year of Sheffield mileage looks front-loaded, because the 55p band is used up in the first six months or so for a full-time driver. After that, each mile is worth 25p. The illustrative example below shows the month in which the switch happens and what each month contributes to the claim.

The 10,000th mile falls in September, 1,000 miles into that month. The first 10,000 miles earn £5,500 at 55p, and the remaining 12,350 miles earn £3,087.50 at 25p. The total claim is £8,587.50.

Under the old 45p rate the first band would have been worth £4,500, giving a total of £7,587.50. The rise is therefore worth £1,000 of extra deduction to this driver, because the full 10,000 miles were driven. If that extra profit would otherwise be taxed at the 20% basic rate, the income tax saving is about £200. Check the current rates and your own position on GOV.UK, because National Insurance and your other income also matter.

Notice what the table says about cash flow. The driver's claim for April to August is close to £1,000 a month, then falls to about £450 by winter. If you set aside tax each month using a flat estimate, you will overpay in the first half of the year and underpay in the second.

Which tax year does my mileage belong to?

Your mileage belongs to the tax year in which you drove it, running from 6 April to 5 April. The 2025/26 year ended on 5 April 2026, so those miles use 45p for the first 10,000. Miles from 6 April 2026 use 55p. Never apply one rate to a mixed log.

This matters now. The deadline for filing the 2025/26 Self Assessment return online is 31 January 2027, and many drivers prepare it in the same weeks as they review 2026/27 mileage. The two returns use different rates for the same job. Our guide to key tax dates for ride-hailing drivers lists the deadlines in order.

What if my accounting year does not match the tax year?

HMRC's policy paper does not say how to split miles or apply the 10,000-mile band when an accounting period straddles 6 April 2026. We therefore cannot give you a firm rule here. If your accounts do not run from 6 April to 5 April, ask your accountant, or email the HMRC business profits team at the address given in the paper, with "Motoring Expenses" in the subject line.

Most self-employed drivers use the tax year as their accounting year, which avoids the question altogether. If you are unsure which applies to you, check the dates on your last Self Assessment return before you start logging for 2026/27.

How do I work out my claim step by step?

You work out the claim by totalling your business miles for the tax year, taking the first 10,000 at 55p and the rest at 25p, then entering the result as your vehicle expense. The steps below take about ten minutes if your log is in good order.

1. Split your log by tax year. Put miles up to 5 April 2026 in one column and miles from 6 April 2026 in another.
2. Remove any journey that is not for business. Home to a regular workplace is not business mileage, and neither are personal trips.
3. Total the 2026/27 business miles for each vehicle you use under the simplified method.
4. Multiply the first 10,000 miles by 55p. If your total is below 10,000, you only use this step.
5. Multiply any miles above 10,000 by 25p, and add the two figures together.
6. Check that you have not also claimed fuel, insurance, servicing or capital allowances on the same vehicle.
7. Keep the log and workings with your records for the period HMRC requires. Our guide to mileage logs and bookkeeping records covers what to store.

You can test your own numbers with the mileage calculator. It applies both bands, so you can see the effect of crossing 10,000 miles.

What counts as business mileage for a Sheffield driver?

Business mileage is travel you make wholly and exclusively for your driving work, such as driving to a pick-up, carrying a passenger or repositioning between jobs. Ordinary commuting and personal journeys do not count. The rules are the same everywhere in the UK, though Sheffield's geography affects where your miles come from.

Sheffield is hilly, spread across several districts and links to the Peak District and the M1. Long runs to Manchester, Leeds or East Midlands airports add long empty return legs. Each of those miles can still be business mileage if the trip is for work, so log the return as well as the fare.

The edge cases are the ones to record carefully, for example waiting at a rank across the city or driving home empty after a late shift. Our Sheffield mileage allowance FAQ answers the commuting questions in more detail, so we do not repeat them here.

What Sheffield costs sit outside the mileage rate?

The simplified rate replaces your vehicle running costs, but GOV.UK says you can claim other travel expenses and parking on top. Whether a licence fee or a Clean Air Zone charge fits in either group depends on what it is for. Ask your accountant before you claim anything alongside the flat rate.

Sheffield City Council driver licensing

To drive a private hire vehicle or hackney carriage in Sheffield you need a council licence, and you must pass every stage of the fit and proper test first. Sheffield City Council's page lists the steps as a taxi certificate, right to work, a knowledge test, a driving standards test, a DBS check, a medical assessment and a photo.

At the time of writing the council lists driver licences for one year at £223, two years at £245 and three years at £268, as shown on its driver licence application page. Fees can change, so confirm them with the council before you budget. Our guide to allowable expenses for ride-hailing drivers explains how licence costs are generally treated.

Sheffield Clean Air Zone

Sheffield's Clean Air Zone charges non-compliant taxis and private hire vehicles, whether they are used privately or for work. The council's page lists £10 a day for smaller vehicles, such as taxis, and says ordinary cars do not pay. You can pay up to six days before you travel, on the day, or up to six days afterwards.

Use the GOV.UK Clean Air Zone vehicle checker to see whether your car is charged, and read the council's Clean Air Zone charges page for the current position. Whether a charge sits inside or outside the mileage claim is a question for your accountant, because the flat rate is meant to replace running costs, not every cost of working. We have not verified the tax treatment on GOV.UK, so we do not state one here.

Should I use the simplified mileage rate or actual costs?

Use the simplified mileage rate if it gives you a larger deduction and you want less record-keeping. Use actual costs if your car is expensive to run or you cover very high mileage. The choice for each vehicle is not a free yearly switch, so compare before your first claim.

HMRC's policy paper says the simplified method must continue to be applied as long as the vehicle is used in the business. That is why the first choice deserves a proper comparison. Our limited company mileage checklist covers the different rules if you run your driving through a company.

What mistakes cause problems with mileage claims?

The most common mistakes are using the wrong rate for the tax year, claiming running costs as well as mileage, and keeping no log. Each can lead to an amended return, a tax bill and sometimes a penalty. The table sets out the likely consequences.

If HMRC opens an enquiry into a mileage claim, get professional representation rather than answering alone. We can help through our HMRC support service. The penalty rules depend on whether an error was careless or deliberate, so check GOV.UK for the current position before you decide what to do.
