Car Mileage Allowance in Sheffield: FAQ Answered for Local Drivers

If you drive for Uber, Bolt or a private hire operator in Sheffield, the car mileage allowance is usually the single biggest deduction on your tax return. This FAQ answers the questions Sheffield drivers actually ask, using HMRC's simplified expenses rates and Sheffield City Council's own licensing and Clean Air Zone rules, not generic guidance copied from elsewhere.

You will find the current rate, worked examples with real numbers, a step-by-step claim process, and the local details that change how much tax you actually save in South Yorkshire.

Key takeaways

• The car mileage allowance for cars is 55p per mile for the first 10,000 business miles, then 25p per mile, for the 2026/27 tax year under HMRC's simplified expenses scheme.
• You must choose either the mileage allowance or actual costs per vehicle and stay with that choice for as long as you own or lease it for business.
• Sheffield's Clean Air Zone charges £10 a day for non-compliant taxis and private hire vehicles; this is a separate allowable expense, not part of the mileage rate.
• A Sheffield City Council private hire vehicle licence and driver licence are required before you can legally drive for Uber in the city.
• HMRC expects a trip-by-trip mileage log, not an end-of-year estimate; poor records are one of the most common reasons claims get challenged.

What is car mileage allowance?

Car mileage allowance is HMRC's flat-rate way of claiming vehicle running costs against your self-employed income, worked out per business mile driven rather than from fuel and repair receipts, and it is the method most Sheffield drivers use.

How much is the car mileage allowance in 2026/27?

For the 2026/27 tax year, the approved mileage rate for cars and vans is 55p per mile for the first 10,000 business miles, then 25p per mile for every mile after that, according to HMRC's simplified expenses guidance. Motorcycles are 24p per mile and bicycles are 20p per mile, though few Sheffield private hire drivers will use these.

This is a rise from the long-standing 45p rate that applied before 6 April 2026, so double-check the figure you use matches the tax year you are claiming for; always check the current figure on GOV.UK rather than relying on an old bookmark or a competitor's outdated blog post. Black cabs and hackney carriages are excluded from simplified mileage and must use actual vehicle costs instead, since HMRC does not allow the flat rate for that vehicle type.

How does simplified mileage compare with claiming actual car costs?

Simplified mileage bundles fuel, servicing, insurance, MOT, repairs and depreciation into one rate per mile, while actual costs means totalling every receipt and applying a business-use percentage. Most Sheffield Uber drivers with an everyday petrol or hybrid car do better on mileage; drivers with an expensive car, or very low annual mileage, sometimes do better on actual costs.

Can I claim both mileage allowance and actual costs?

No, you cannot mix the two methods for the same vehicle. Once you claim simplified mileage for a car in the first tax year you use it for business, HMRC requires you to keep using that method for that vehicle until you replace it or stop using it for work.

Does driving from home to my first Sheffield pickup count as business mileage?

Yes, in most cases, because the moment you switch the Uber or Bolt app on and start looking for fares, HMRC generally treats that as the start of a business journey rather than ordinary commuting. Keep a note of your app-on and app-off times alongside your mileage log, since that is the evidence an HMRC check would ask for.

What about the Sheffield Clean Air Zone charge?

Sheffield's Clean Air Zone has applied since February 2023 and charges non-compliant taxis, private hire vehicles, vans and heavier vehicles £10 a day, according to Sheffield City Council's charges page. Private cars and motorbikes are never charged under Sheffield's Class C zone.

If your Clean Air Zone charge relates to a business journey, it is an allowable expense claimed separately from your mileage allowance, so keep the payment confirmation alongside your mileage log as evidence. Use the GOV.UK Clean Air Zone vehicle checker to confirm whether your car, based on its Euro emissions standard, is exempt before you budget for the daily charge.

What private hire licensing rules apply in Sheffield?

You need three separate approvals from Sheffield City Council before driving for hire in the city: a driver licence, a vehicle licence, and, if you are not working through an existing operator, an operator licence. Fees and vehicle age limits are set by the council and reviewed periodically, so check current rules on Sheffield City Council's site before buying or leasing a car.

Vehicle age limits directly affect your mileage planning. Newer, compliant cars avoid the Clean Air Zone charge and are licensable for longer under the council's rules for zero-emission-capable vehicles.

How do I claim mileage allowance on my Self Assessment return?

You do not submit your mileage log itself to HMRC, but you must be able to produce it if asked, and the total mileage deduction is entered on your Self Assessment return as a business expense. Work out the figure first, then follow the steps below so the number on your return matches your own records exactly.

1. Keep a mileage log for every business trip: date, start point, destination, purpose and miles driven, ideally recorded on the day using an app or a simple spreadsheet.
2. Add up total business miles for the tax year, splitting the first 10,000 miles from any miles over that threshold.
3. Apply the rate: 55p per mile for the first 10,000 business miles, then 25p per mile after that, for 2026/27.
4. Enter the total as an allowable expense on the self-employment pages of your Self Assessment return, alongside any other allowable costs like phone, licensing fees or the Clean Air Zone charge.
5. Keep your mileage records and any supporting evidence for at least five years after the 31 January filing deadline, in case HMRC opens a check.

Illustrative example: a Sheffield driver's mileage claim

Aisha drives for Uber around Sheffield city centre and Hillsborough, logging 14,200 business miles in the 2026/27 tax year. Her first 10,000 miles are claimed at 55p, giving £5,500. The remaining 4,200 miles are claimed at 25p, giving £1,050. Her total mileage allowance for the year is £6,550, before any other allowable expenses such as her phone bill, licensing fees or Clean Air Zone charges on non-compliant days.
