Car Mileage Allowance in Newcastle: Year-End Checklist for Local Drivers

The car mileage allowance lets a self-employed Newcastle driver claim a flat rate for every business mile instead of listing fuel, insurance and repairs. For 2026/27 the rate is 55p a mile for the first 10,000 miles and 25p after that. This is a compact year-end checklist, so you can test your own records before your tax return. For the full how-to, read our Newcastle mileage step-by-step guide.

Most mileage claims go wrong in the records, not the sums. A missing date, a commute logged as a business trip or the wrong tax year can undo a claim worth thousands. Work through the ten checks below in order. Each one explains what to do, what to avoid and where Newcastle's tunnel tolls and Clean Air Zone fit in.

Key takeaways

• The 2026/27 flat rate is 55p for the first 10,000 business miles and 25p after, per GOV.UK.
• Tolls, congestion charges and parking sit on top of the flat rate, but only when they are solely for business.
• Fines and penalty charge notices are never claimable, and neither is travel between home and work.
• Once you use the flat rate on a vehicle you must keep using it for as long as that vehicle is in the business.
• Hackney carriages (black cabs) cannot use the flat rate and need the actual-costs method.

What is the car mileage allowance?

The car mileage allowance, called simplified expenses by HMRC, is an optional flat rate per business mile that replaces your actual vehicle costs. It covers fuel, insurance, servicing, repairs, road tax, MOT and depreciation. Only sole traders and partnerships with no company partner can use it.

Key terms

• Simplified expenses: HMRC's flat-rate method for vehicle, home-working and business-premises costs.
• Actual costs: claiming the business share of what you really spent running the vehicle, plus capital allowances.
• Capital allowances: tax relief for buying a vehicle or equipment. Claiming them stops you using the flat rate on that vehicle.
• CAZ: Clean Air Zone, a charging area for vehicles that fail emission standards.
• PHV: private hire vehicle, a licensed car booked through an operator such as Uber or Bolt.
• PCN: penalty charge notice, a fine for not paying a charge or breaking a traffic rule.

Why do Newcastle drivers need a separate year-end checklist?

Newcastle drivers face costs that drivers in many other cities do not, notably the Tyne Tunnel toll and a Clean Air Zone covering the city centre. These costs interact with your mileage claim in ways that catch people out. A year-end review stops you double-counting costs or missing allowable ones.

The flat rate is designed to be simple, but the simplicity hides some firm rules. According to HMRC's guidance on simplified expenses for vehicles, the 2026/27 rate is 55p for the first 10,000 miles and 25p after, against 45p and 25p before 6 April 2026. A checklist makes sure you apply the right year's rate to the right miles.

This article assumes you are a sole trader. If you are thinking about trading through a company, the mileage rules change completely, so see our Newcastle limited company guide first. Our Newcastle driver accountant page covers the wider picture for local drivers.

Check 1: Are you using the right method for your vehicle?

Confirm you can use the flat rate before logging a single mile. GOV.UK says cars (except those designed for commercial use, such as black cabs and hackney carriages), vans and motorcycles qualify. You cannot use it on a vehicle where you have already claimed capital allowances.

Newcastle has a large licensed hackney carriage trade, so this matters locally. A black cab driver must claim actual costs and capital allowances. A private hire driver in an ordinary saloon or electric car can choose either method, and the flat rate is often simpler.

Remember the lock-in rule. HMRC's Business Income Manual says that once you adopt the mileage rate for a vehicle, you apply it consistently for as long as that vehicle stays in the business. You can only switch to actual costs when the vehicle is replaced. Think hard before choosing, especially if you plan to buy an expensive electric car.

Check 2: Does every log entry have the right fields?

A mileage log needs enough detail that a stranger could follow each journey. HMRC expects a contemporaneous record, meaning you write it at the time or soon after, not months later. Our guide to HMRC mileage log records and bookkeeping goes deeper on format.

Run through your log and confirm each entry has these fields:

• The date of the journey.
• The start and end location, such as Central Station to Newcastle Airport.
• The odometer readings at the start and end, or the trip distance.
• The business purpose, for example a booked airport transfer.
• The vehicle registration, if you use more than one vehicle.
• Any toll, parking or congestion charge paid on that trip.

Also record your odometer on 6 April and 5 April each year. Those two readings give you total yearly mileage, so you can show the business share of the total. It is a simple cross-check that makes your log far more convincing.

Check 3: Have you separated business, private and commuting miles?

Only business miles earn the allowance. According to GOV.UK's guidance on self-employed travel expenses, personal travel and travel between home and work are not allowable. The Business Income Manual adds that a journey serving both a business and a private purpose does not qualify for the flat rate.

For a private hire driver the grey area is the drive to your first job. If you start a shift at home and head to a busy pickup zone, ask whether this is a business trip or a commute. HMRC's rule is strict, and a recorded journey that mixes purposes is risky. If a trip was part business and part personal, log only the clearly business part, or leave it out.

Do not rely on your log alone as proof of work. Your platform statements show the trips you actually completed, and those should match your log reasonably closely. A log full of business miles with no matching platform earnings invites questions.

Check 4: Are you counting miles when you drive without a passenger?

Yes, in many cases waiting and repositioning miles can be business miles if they are genuinely part of earning your income. Driving to collect a passenger is business travel, and so is driving between jobs. The test is wholly and exclusively for business, so mixed trips are different.

Be honest about this category. Driving around Newcastle looking for work is business, but a detour to a friend's house on the way is not. Keep your log truthful, because inflating mileage is the fastest route to an HMRC enquiry. Our allowable expenses guide explains what else counts.

Check 5: How are Tyne Tunnel tolls treated?

Tyne Tunnel tolls are claimed separately from the flat rate, as long as they were incurred solely for business. HMRC's Business Income Manual says the mileage rate does not cover incidental costs such as tolls, congestion charges and parking fees, and these are allowable where they are solely for business purposes.

The Tyne Tunnel operator states that from 1 May 2026 the car toll is £2.60 a crossing, or £2.34 for pre-paid account holders who get a 10% discount. You can check the current figure on the Tyne Tunnels toll changes page. Tolls before that date were lower, so match each receipt to its date.

Keep your toll records in one place. A pre-paid account statement is ideal because it lists every passage with a date and time. Tick off the crossings that were genuine business trips and total them for the tax year. Private crossings, such as a family trip to the coast, are not claimable.

If a passenger pays the toll as part of the fare, check how your platform treats it before claiming it again. Claiming a cost you were reimbursed for is double counting. When in doubt, ask your accountant.

Check 6: How does the Newcastle Clean Air Zone fit in?

The Newcastle and Gateshead Clean Air Zone is a Class C zone, which GOV.UK lists as covering buses, coaches, taxis, private hire vehicles, heavy goods vehicles, vans and minibuses. It does not charge private cars. For an Uber driver it matters because licensed private hire vehicles are in scope.

GOV.UK's clean air zone service lists Tyneside, Newcastle and Gateshead among the zones where you check a number plate and pay any daily charge. The emission standards for taxis and private hire vehicles in a clean air zone are Euro 6 for diesel and Euro 4 for petrol, per GOV.UK's clean air zone guidance. At launch the councils announced a £12.50 daily charge for non-compliant taxis and private hire vehicles, but check the current figure on GOV.UK before relying on it.

For your tax return, there are two separate questions. First, does a CAZ daily charge count as an allowable cost? HMRC's manual names tolls, congestion charges and parking, and a CAZ charge is similar in nature, but it is not named, so confirm the treatment with your accountant. Second, a penalty charge notice is a fine. GOV.UK says fines and penalty charges are not allowable.

Newcastle City Council also phases emission rules into its licensing policy for private hire vehicles, according to its published policy. Check the council's current policy before you buy or replace a car, because a vehicle that cannot be licensed has no business mileage to claim.

Check 7: Have you split the 10,000 miles correctly?

The 55p rate applies to your first 10,000 business miles in the tax year, and 25p applies to every mile after that. The split runs across the whole year for the vehicle, not per month. Your tax year runs from 6 April to 5 April.

Work out the split from your yearly total. Multiply the first 10,000 miles by 55p, then the remainder by 25p, and add the two. GOV.UK gives the same method in its own worked example. You can also test your figures with our mileage calculator.

That example uses made-up figures to show the method. Your own claim depends on your real log, and the tax you save depends on your total profit and tax band.

Check 8: Are you using the correct rate year?

Use the rate for the tax year in which the journey happened. Journeys on or before 5 April 2026 belong to 2025/26, when the rate was 45p for the first 10,000 miles. Journeys from 6 April 2026 belong to 2026/27 at 55p. This is a common slip when drivers log a full calendar year.

If you drive across a year boundary, split your records at 5 April. Count the 10,000-mile threshold fresh in each tax year. The GOV.UK vehicles page shows both columns, so save it for your records.

Rates can change again, so always check GOV.UK for the year you are filing. Our key tax dates guide helps you plan the filing year around the 31 January deadline.

Check 9: Have you kept the right other records?

Mileage is one record among several. GOV.UK's self-employed records guidance sets out what to keep and for how long. Alongside the log, keep your platform earnings statements, toll and parking receipts and, if you use actual costs, every vehicle receipt.

1. Export your platform earnings statements for the whole tax year.
2. Download your pre-paid Tyne Tunnel account statement.
3. Collect parking receipts and any permit invoices.
4. Confirm your odometer readings at 6 April and 5 April.
5. Total your business miles and apply the 10,000-mile split.
6. Add tolls and parking as separate lines.
7. Save everything in one folder and back it up.

Store the files digitally with a clear naming system. A folder per tax year is enough. Having it organised in October is much less stressful than hunting for it on 30 January.

Check 10: Is your mileage claim consistent with your whole return?

Your mileage claim must tell the same story as the rest of your return. If you claim 20,000 business miles but report earnings that could not support that driving, HMRC may query the mismatch. Compare your claim to your platform trips and total income.

Check that you have not claimed fuel, insurance or repairs for the same vehicle as well as the flat rate. That is double claiming. Also confirm you have not claimed capital allowances on the car, since that bars the flat rate. Our personal tax service reviews exactly these cross-checks.

What is the process for a year-end mileage review?

A year-end review takes about an hour if your records are tidy. Work through the checks above in sequence, correct any gaps while memory is fresh and total your figures. The numbered steps below summarise the order that works best for Newcastle drivers.

1. Confirm your vehicle qualifies for the flat rate and note which method you chose.
2. Check every log entry has the date, route, distance and purpose.
3. Remove commuting, private and mixed journeys.
4. Total business miles and split them at 10,000 using the correct year rates.
5. List business Tyne Tunnel crossings and parking separately.
6. Note any CAZ charges and ask your accountant how to treat them.
7. Exclude fines and penalty charge notices.
8. Cross-check against platform trips and total income.
9. Save your records and file by 31 January 2027 for the 2025/26 return, or by the deadline for your return year.

Common mistakes and the penalty each triggers

The mistakes below are common and each carries a cost. Penalties depend on whether HMRC sees an error as careless, deliberate or accidental, so check GOV.UK for current rules before assuming a figure.

• Claiming commuting as business miles: HMRC can remove the deduction, charge extra tax and add a penalty for an inaccurate return.
• No contemporaneous log: the claim can be rejected, leaving you with extra tax and interest.
• Using the wrong year's rate: your claim is overstated or understated, which may mean an amended return.
• Claiming flat rate and actual costs on one vehicle: this double claim is treated as an error.
• Claiming a fine or PCN: not allowable, so the deduction is removed.
• Switching methods mid-life: you are bound to the flat rate while you keep that vehicle.
• Inflated mileage: deliberate over-claiming can lead to the highest penalties and an investigation.

If HMRC opens an enquiry or issues a penalty, get professional representation rather than responding alone. Our HMRC support service exists for that situation.

Is it worth using the flat rate if I mostly drive an electric car?

Often yes. The flat rate gives you 55p a mile for the first 10,000 miles whatever powers the car, and it covers your running costs, including charging. The better method depends on the car's cost and your yearly mileage, so run both numbers using the GOV.UK simplified expenses checker.

Newcastle's Clean Air Zone is a further consideration. Newer low-emission cars are more likely to meet the standard, which helps your licence and your running costs. Because you are locked into the method for the vehicle's life, compare both methods before you commit.
