Self Assessment for London Uber Drivers: The TfL and Clean Air Costs That Matter

If you drive for Uber in London, you file the same Self Assessment tax return as a driver in Leeds or Glasgow. The personal allowance, Income Tax bands and National Insurance rates are identical across England. What sets a self assessment London Uber driver apart is the cost side: Transport for London (TfL) licensing, central-zone charges and heavy stop-start mileage.

This guide covers the London private hire driver tax return from start to finish for the 2026/27 tax year. We explain what TfL licensing means for your expenses, how to treat Congestion Charge and ULEZ payments, and the records that keep your claims safe. One point up front: TfL's website blocked our automated checks this time, so we quote no TfL charge or fee figure. We link to TfL instead, and you should confirm the current amounts there.

Key takeaways

• London does not change your tax rates, but it does change your allowable costs: TfL licences, DBS and test fees, and zone charges you pay yourself.
• The online return for 2025/26 is due by 31 January 2027, and any tax owed is due the same day.
• Congestion Charge and ULEZ payments for business trips are normally deductible, but penalty charge notices generally are not.
• Do not assume a private hire vehicle (PHV) gets an exemption or discount from TfL charges. Check TfL's pages for your own vehicle.
• Keep receipts, TfL statements and a mileage log as you go. Rebuilding them each January is where London drivers lose claims.

What is a self assessment for a London Uber driver?

A self assessment for a London Uber driver is the annual tax return in which you report your driving income and allowable costs to HMRC. It calculates your Income Tax and Class 4 National Insurance on the profit. London licensing and zone charges appear as expenses within that same return.

Why does London driving feel different at tax time?

London feels different because your costs are different, not your rules. TfL licenses private hire drivers and vehicles in the capital, most councils elsewhere in England do that job, and central London has charging zones that many other cities lack. Each of those creates payments you must record and claim correctly.

The tax treatment itself is the same everywhere. You take your total driving income, subtract allowable expenses, and pay tax on the profit. HMRC does not ask which borough you worked in. If you are new to all this, our guide to a first tax return for a new Uber driver walks through the basics before you add the London detail.

How does TfL private hire licensing affect my tax return?

TfL licensing affects your return because the costs of getting and keeping your licences are business expenses. Fees for your driver licence, your vehicle licence and the checks behind them normally reduce your taxable profit. You need proof of payment for each item, and any private element must be left out.

TfL is the licensing authority for private hire in London. It sets the requirements and publishes the current fees on its own website, so check the TfL taxis and private hire licensing pages for the up-to-date process and costs. We do not quote fee amounts here because we could not verify them this run.

Licensing costs you can usually claim

• Private hire driver licence application and renewal fees
• Private hire vehicle licence fees for the car you drive
• DBS (criminal record) check fees required for the licence
• Medical, English language or topographical assessment fees, where you had to pay them
• Vehicle inspection or testing fees needed to keep the vehicle licensed

Keep the payment confirmation, not just the licence itself. A licence shows you held it; only a receipt shows what it cost you and when. Our guide to allowable expenses for Uber drivers lists every other category that sits alongside these.

The licence renewal tax check

There is one tax rule attached to licensing itself. According to GOV.UK's guidance on the tax check for taxi and private hire licences, you must complete a tax check when you renew, or reapply within a year of expiry. You get a 9-character code to give your licensing authority.

GOV.UK says you must do the check yourself, and an accountant cannot do it for you. The code expires after 120 days, so complete it close to your renewal. Without a valid code, your licence can end. The check confirms you are registered for the right taxes, which is one more reason to keep your Self Assessment up to date.

How are the Congestion Charge and ULEZ treated for tax?

Congestion Charge and ULEZ payments for business journeys are normally allowable expenses, so they reduce your taxable profit. You can only claim what you paid and were not repaid. Penalty charge notices for missed payments are generally treated differently and are not usually allowable. Keep every payment record.

The Congestion Charge and the Ultra Low Emission Zone (ULEZ) are separate TfL schemes with separate rules, areas and hours. The Congestion Charge applies to central London. ULEZ depends on your vehicle's emissions standard, and it covers a much wider area. For current charges, hours, boundaries and vehicle standards, see the TfL Ultra Low Emission Zone page.

Are private hire drivers exempt from the Congestion Charge?

Do not assume that any private hire vehicle is exempt or discounted. Rules on exemptions and discounts are set by TfL and can change. We could not confirm the current position for private hire vehicles this run. Check the TfL discounts and exemptions pages for your exact vehicle before relying on any rumour.

This matters for tax as well as budgeting. If a charge does not apply to you, you cannot claim it. If it does apply and you pay it, you claim what you paid. In both cases the receipt is what supports your figure.

What if the platform pays or refunds part of the cost?

You can only claim a cost you bore yourself. If any part of a zone charge is paid or refunded to you, that part is not your expense. Treat it consistently: either the platform's payment sits in your income and the full cost is claimed, or you claim only the net cost. Do not count the same money twice.

Read your platform statements carefully so you know which items are fares, which are fees and which are reimbursements. If the picture is unclear, ask a qualified accountant to check it before you file. It is easy to overclaim by mistake when payments and refunds are mixed together.

Which London driving costs can I claim?

You can claim costs you incur wholly and exclusively for your driving business, such as vehicle rental or finance interest, fuel or charging, insurance, licences, zone charges you pay, phone use and accountancy fees. GOV.UK lists travel costs, including fuel and parking, as allowable. Personal costs and cash you take out for yourself are not.

According to HMRC's guidance on expenses if you're self-employed, allowable expenses do not include money taken from your business for personal use. GOV.UK also says you cannot claim expenses if you choose the £1,000 trading allowance instead, because it is one method or the other.

Should I use simplified mileage or actual costs?

Simplified mileage lets you claim a flat rate per business mile instead of tracking fuel, servicing and depreciation. Actual costs let you claim what you really spent. Which is better depends on your car, and you generally must pick one method per vehicle. Compare both before your first return using a proper mileage record.

The simplified rates were being changed for 2026/27 as we prepared this, so check the current figures on GOV.UK's simplified expenses pages rather than relying on an older number. You can test both routes with our mileage calculator. Either way, keep the log described in our guide to mileage logs and bookkeeping records.

Why London mileage needs extra care

London driving mixes short hops, waiting time and slow traffic, so a year-end guess is unreliable. HMRC can ask for records that show how you reached a figure. A log with date, start, finish and purpose stands up far better than an estimate. Log trips as you work, or use an app that records them.

How do I file a London Uber driver tax return step by step?

You file by registering with HMRC, collecting your records, working out income and expenses for the tax year, completing the online return and paying any tax due. The steps below apply to any Uber driver in London, and each one has a date attached for the 2025/26 return.

1. Register for Self Assessment and get your Unique Taxpayer Reference (UTR, your 10-digit tax reference) if you are new. GOV.UK says to register by 5 October 2026 if this is your first return.
2. Download your Uber statements for 6 April 2025 to 5 April 2026 and add any income from other apps or work.
3. Gather receipts and statements for TfL licences, vehicle costs, insurance, phone and any zone charges you paid.
4. Add up business miles from your log, then choose simplified mileage or actual costs and stick with it.
5. Log in to your HMRC online account, complete the self-employment pages and check the profit figure before you submit.
6. Send the return by 31 January 2027 and pay the tax due by the same date, or set up a payment plan with HMRC if you cannot pay in full.

According to GOV.UK's Self Assessment deadlines page for 2025/26, paper returns must reach HMRC by 31 October 2026 and online returns by 31 January 2027. Our page on key tax dates for Uber drivers puts every date for the year in one place.

What tax will a London Uber driver pay?

You pay Income Tax and Class 4 National Insurance on your profit, which is fares minus allowable expenses. For 2026/27, the personal allowance is £12,570. Income Tax is 20% on profit up to £50,270, and Class 4 National Insurance is 6% between £12,570 and £50,270. These are the same for every driver in England.

These rates come from GOV.UK's Income Tax rates and allowances page, and the National Insurance rates come from the self-employed National Insurance rates page, both for 2026/27. If your other income takes you over £100,000, the personal allowance reduces, so higher earners should check their own position.

Illustrative example

Illustrative example: Sam is an invented London Uber driver with £36,000 of total fares in a tax year and no other income. These are not TfL fees, and the figures are round numbers chosen to show how the calculation works.

Sam's profit is £22,160, so £9,590 is taxable after the £12,570 allowance. Class 2 is not payable as a charge because profits are above the £7,105 level, and GOV.UK treats the year as paid for National Insurance record purposes. Because Sam's bill is over £1,000, HMRC will normally ask for two payments on account of £1,246.70 towards next year.

GOV.UK explains that payments on account are due on 31 January and 31 July, and you avoid them if last year's bill was under £1,000 or you already paid over 80% another way. This is why a new London driver's first January bill can feel much larger than expected. Set aside part of each week's earnings.

What records should a London PHV driver keep?

Keep every income statement, every expense receipt and a mileage log for the whole tax year. GOV.UK says self-employed people must usually keep records for at least 22 months after the end of the tax year if they file on time. Inaccurate or incomplete records can lead to an HMRC penalty.

• Uber, and any other app, statements for each week or month
• Bank statements from a separate account used for driving, which makes everything easier
• TfL licence, vehicle licence and check payment confirmations
• Congestion Charge and ULEZ payment records with dates
• Fuel, charging, servicing, insurance and finance statements
• A mileage log recording date, start, end and business purpose

GOV.UK's guidance on how long to keep records gives the current retention periods. If you file late, the period is longer, so keep everything until you are sure you no longer need it.

Does Making Tax Digital affect London Uber drivers?

Making Tax Digital (MTD) for Income Tax affects you if your qualifying income is over the threshold, which is £50,000 from 6 April 2026, £30,000 from 6 April 2027 and £20,000 from 6 April 2028. Qualifying income is gross self-employment income before expenses. Below the threshold, you continue with a normal annual return.

GOV.UK's page on when you need to use Making Tax Digital for Income Tax explains that HMRC looks at an earlier Self Assessment return to decide. Because London drivers often have high gross fares, the threshold is easy to pass, so read our guide to Making Tax Digital for Uber drivers early.

What are the common mistakes London Uber drivers make?

The most common mistakes are missing deadlines, claiming costs you did not pay, failing to keep records and forgetting to register at all. Each carries a penalty or an HMRC enquiry risk. Most are avoidable with a simple monthly routine and a clear separation between business and personal spending.

The figures above come from GOV.UK's Self Assessment penalties page: a £100 initial late filing penalty, and late payment penalties of 5% at 30 days, 6 months and 12 months. If HMRC disputes your return or opens an enquiry, professional representation is recommended.
