    Tax for UK taxi + PHV drivers

    UK taxi + PHV drivers operate as sole traders (most common, including platform drivers for Uber/Bolt), owner-drivers with their own vehicle, or as employees of a fleet (PAYE). The Hackney carriage / PHV split affects licensing + pick-up rights but tax mechanics are largely the same. Simplified mileage 45p/25p typically wins given high annual business miles (15,000-40,000+ common). Hire-and-Reward insurance is non-negotiable, standard motor insurance is void for paid-passenger work. The 2021 Uber Supreme Court decision established platform drivers as 'workers' for employment rights while typically remaining self-employed for tax purposes.

    UK taxi + PHV drivers are mostly sole-trader owner-drivers with high annual business miles. Tax mechanics are vehicle-heavy: simplified mileage usually wins; Hire-and-Reward insurance is non-negotiable; platform commission deducted at source from app-based earnings; ULEZ + Clean Air Zone fees add to running costs in major UK cities. The 2021 Uber Supreme Court decision created a 'worker' status for employment rights but didn't change the self-employment tax position for most drivers.

    What business structure do taxi + PHV drivers use?

    The common patterns for taxi + PHV drivers are: Sole trader owner-driver (Hackney), own black cab / saloon, council-licensed, can pick up street + rank, Sole trader owner-driver (PHV), pre-booked work via Uber/Bolt/local firm; most platform drivers, Sole trader contracting to fleet, rent vehicle from fleet, self-employed for tax (status risk if fleet controls work), Multi-vehicle Ltd Co (taxi firm operator), owns vehicles + employs drivers (PAYE) or contracts to self-employed drivers. The right structure depends on revenue, liability exposure, and personal circumstances, covered below.

    Mileage method choice, the dominant decision

    Taxi + PHV drivers typically do high annual business mileage (15,000-40,000+ common). Method choice affects tax outcome substantially. Simplified mileage method: 45p first 10,000 business miles + 25p above. Easy admin (just log business miles). For a driver doing 25,000 business miles: (10,000 × 0.45) + (15,000 × 0.25) = £4,500 + £3,750 = £8,250 deduction. Actual cost method: fuel + servicing + insurance + tyres + tax + depreciation × business-use percentage. For a typical taxi vehicle at 35mpg, fuel cost for 25,000 miles ≈ £3,800; insurance £1,500 (Hire-and-Reward); servicing + tyres ≈ £1,500; tax + MOT ≈ £350; depreciation £2,500-£4,000 = £9,650-£11,150 total. With 90% business-use: £8,685-£10,035. Actual cost usually wins for taxi drivers with full-time vehicle use because depreciation + Hire-and-Reward insurance + high running costs exceed simplified mileage. Once chosen for a vehicle, method is locked for the life of that vehicle. VAT recovery: if VAT-registered (rare for sub-£90k taxi drivers), input VAT on fuel + servicing + parts recoverable. Most stay below threshold + don't VAT-register.

    Simplified mileage rates: 45p first 10,000 business miles + 25p above; actual cost method tracks all vehicle expenses × business-use percentage. Method choice locked once made for a vehicle. (ITTOIA 2005 s.94D + HMRC-published mileage rates; HMRC manual BIM75000)

    Hire-and-Reward insurance + business-use compliance

    Standard motor insurance does NOT cover paid passenger transport. Hire-and-Reward (H&R) insurance is required for ANY paid taxi work, Hackney, PHV, Uber/Bolt platform, private bookings, even occasional cash jobs. H&R premiums substantially higher than standard motor insurance, £1,500-£3,500/year typical for taxi drivers. Specialist insurers: Acorn, Hagerty, Adrian Flux, Brunswick, Connect. Key cover types: - H&R Comprehensive: vehicle + passenger + third-party liability + own damage - Public Liability (PL): third-party injury beyond motor insurance (e.g. passenger trips getting out of vehicle) - Loss of Use cover: replacement vehicle if yours is in repair HMRC + insurer cross-referencing: DVLA data + insurance records + Companies House + platform data (Uber/Bolt) are increasingly cross-matched. Driving for paid work on standard motor insurance = void insurance + potentially uninsured driving offence + HMRC enquiry trigger. Flexible H&R policies: some specialist insurers offer 'platform-only' policies for Uber/Bolt drivers (cheaper than full Hackney H&R because no street pick-ups). Verify your policy covers ALL the work you actually do.

    Hire-and-Reward (H&R) insurance required for any paid passenger transport; standard motor insurance is void for paid work; specialist H&R insurance premiums £1,500-£3,500/year typical. (Road Traffic Act 1988 + Motor Insurance Bureau requirements; HMRC manual VAT Notice 700 (insurance treatment) + standard trade practice)

    ULEZ + CAZ + EV taxi transition

    Clean Air Zones are an increasing operational cost for taxi drivers in major UK cities: - London ULEZ (Ultra Low Emission Zone): £12.50/day for non-compliant vehicles. Expanded to all London boroughs in August 2023. Tax-side: ULEZ charges paid for genuinely business journeys are allowable revenue expenses. - Birmingham CAZ (Clean Air Zone): £8/day for non-compliant taxis + PHVs. - Manchester GM Clean Air Zone (delayed, future implementation TBC). - Bath, Bristol, Sheffield, Newcastle: variable CAZ schemes. ULEZ-compliant vehicles: Euro 6 diesel (most diesel from 2015 onwards) or Euro 4 petrol (most petrol from 2006 onwards). Most current PHV vehicles are compliant; older Hackney carriages may not be. EV taxi transition: TfL has been phasing in zero-emission requirements for new London Hackney licences. Council areas vary. EV taxi vehicles: 100% First-Year Allowance for zero-emission cars (Capital Allowances Act 2001 s.45D). For a £40,000 EV taxi (LEVC, etc.), full £40,000 FYA in year of purchase = substantial tax benefit even for car-class vehicles. Vehicle replacement strategy: many taxi drivers transitioning to EV before older diesel vehicles fall out of compliance. Time the purchase to maximise FYA in a high-profit year.

    Clean Air Zone charges (ULEZ, Birmingham CAZ, etc.) on business journeys are revenue expenses; EV taxis qualify for 100% First-Year Allowance on car-class vehicles (vs standard 18% WDA for non-EV cars). (Capital Allowances Act 2001 s.45D + ULEZ Regulations 2015 + various CAZ Orders; HMRC manual CA23153 + HMRC environmental tax guidance)

    Allowable expenses

    Category Examples Tax treatment
    Vehicle costs Either simplified mileage 45p/25p OR actual cost (fuel + servicing + tyres + insurance + tax + depreciation × business %) Method locked once chosen per vehicle
    Hire-and-Reward insurance Specialist H&R policy covering passenger transport + PL + own damage Revenue expense (separate from simplified mileage if claiming that method)
    Platform commission Uber commission (~25%), Bolt commission (~15-25%), other platform commission deducted at source Revenue expense (gross fare = income; commission = expense)
    Licensing + DVSA compliance Council PHV licence renewal, Hackney plate renewal, TfL fees (London), medical, DBS check, topographical test, Knowledge of London (Hackney) Renewal allowable; initial licence pre-trading expenditure
    Phone + apps Mobile phone bill (business %), navigation apps (Waze + Google Maps premium), platform driver apps + premium subscriptions, vehicle logbook apps Revenue expense (apportion for business use)
    Vehicle accessories + signage Taxi top sign, fare meter (Hackney), card payment terminal, dash cam, passenger amenities (water + sweets if provided) AIA-eligible if above £500; smaller items revenue expense
    ULEZ + CAZ + congestion + parking Business journey ULEZ charges, congestion charges, CAZ charges, parking for fare drop-offs (NOT parking penalties, never allowable) Revenue expense for business journeys only
    Vehicle cleaning + valeting Regular interior + exterior cleaning between shifts, professional valeting Revenue expense (business hygiene requirement)

    Vehicle and travel costs

    Taxi + PHV drivers' vehicle is the primary capital asset + the dominant expense category. Most use simplified mileage method despite high business miles because record-keeping is simpler. Actual cost method usually wins when factoring in depreciation + Hire-and-Reward insurance + ULEZ charges. EV taxis benefit from 100% First-Year Allowance for zero-emission cars, significant tax break. Personal car insurance is void for any paid work; Hire-and-Reward essential.

    Capital allowances and equipment

    Typical EV taxi purchase (LEVC TX5 £65,000 or used model £35-45k): zero-emission car qualifies for 100% First-Year Allowance, full purchase price deductible in year of purchase. For a sole trader with £35k profit before allowances, a £40,000 EV taxi creates a £5,000 trading loss available for sideways relief or carry-forward. Non-EV cars (older diesel + petrol taxis) get only 18% WDA main pool or 6% special rate pool. Vans configured for taxi use (rare, minicab MPVs sometimes) get AIA. Vehicle replacement strategy + EV transition timing has substantial tax-optimisation potential.

    Worked example

    Hassan — Manchester, England

    sole trader PHV driver (Uber + Bolt + private bookings, third year) (2025/26)

    Annual revenue 2025/26: Uber gross fares £24,000 (net of £6,000 platform commission = £18,000 received), Bolt gross fares £14,000 (net of £3,000 commission = £11,000 received), private bookings £6,000. Total gross fare value £44,000. Business miles 28,000 (simplified mileage method chosen 2 years ago = locked). Hire-and-Reward insurance £2,400. PHV licence renewal + medical + DBS £180. Phone + apps £420. Card terminal + dash cam + signage £350.

    Gross revenue for tax = £44,000 (full fare value before platform commission). Expenses: platform commission £9,000 + simplified mileage (10,000 × 0.45) + (18,000 × 0.25) = £4,500 + £4,500 = £9,000 + insurance £2,400 + licensing £180 + phone/apps £420 + accessories £350 = £21,350.

Net trading profit: £44,000 - £21,350 = £22,650.

Income tax: personal allowance £12,570 = nil. Basic rate 20% on £10,080 (£12,571 to £22,650) = £2,016.

Class 4 NI on profits above £12,570: 6% on £10,080 = £605.

Total SA liability: £2,016 + £605 = £2,621. Payments on account for 2026/27: £1,311 each on 31 January 2027 + 31 July 2027.

VAT note: £44,000 below £90,000 threshold, no VAT registration. Most PHV drivers stay below threshold; the Uber 'worker' question is separate from VAT.

ULEZ + CAZ note: Hassan's vehicle is Euro 6 diesel (ULEZ + Manchester CAZ compliant when implemented). If he transitions to an EV next year, the 100% First-Year Allowance on the new vehicle creates a substantial tax break + ongoing fuel savings, modelled separately.

    Frequently asked questions

    What happens if I miss the Self Assessment deadline?+
    The Self Assessment deadline is 31 January (online filing) for the previous tax year. Miss it and HMRC apply an automatic £100 penalty. Beyond that: £10 per day from 3 months late (capped at £900), 5% of tax due at 6 months late, and another 5% at 12 months late, under Schedule 55 of the Taxes Management Act 1970. If you have a genuine reason (serious illness, bereavement, technical issue with HMRC's systems) you can appeal with evidence; HMRC accepts reasonable excuse appeals in most genuine cases.
    Do I need an accountant or can I file Self Assessment myself?+
    Legally you can file Self Assessment yourself via gov.uk for free, most simple sole-trader returns (single income source, basic expenses) are realistic to self-file. An accountant adds real value when: your trading profit is above £40,000 (extraction-strategy decisions matter), you have multiple income streams (PAYE + self-employment + property + dividends), you've crossed the £90,000 VAT threshold, you're considering incorporation, or you have an HMRC enquiry. Expect to pay £400-£1,500/year for a typical sole-trader accountant; the cost is itself a deductible expense.
    How do payments on account work?+
    When your Self Assessment tax bill exceeds £1,000 for the first time, HMRC requires payments on account toward NEXT year's tax. Half the current bill is due 31 January (alongside the current bill); the other half is due 31 July. So your first January after crossing the threshold can hit with a double-bill: last year's balance + first payment on account. Adjust via Form SA303 if you expect next year's income to drop substantially. Payments on account don't apply if more than 80% of your tax is collected via PAYE.
    What's the difference between Hackney carriage and PHV for tax purposes?+
    For TAX purposes, no meaningful difference, both are self-employment trading income with the same allowable expenses + same mileage rules + same VAT mechanics. For LICENSING + OPERATIONAL purposes, big differences: Hackney carriages can pick up passengers from the street + ranks (TfL-regulated black cabs in London, council-regulated elsewhere); PHVs are pre-booked only (Uber, Bolt, local minicab firms). Hackney licensing is harder + more expensive (Knowledge of London for black cab; specific Hackney plate elsewhere); PHV licensing is more accessible. Both pay tax the same way.
    If I drive for Uber and Bolt at the same time, do I have two businesses?+
    One business, taxi driving is a single trade regardless of how many platforms you work through. All Uber income + all Bolt income + any cash jobs + any private bookings combine into one Self Assessment trading income figure. All expenses (fuel, insurance, mileage, platform commission, phone, licensing fees) combine into one expense pool. Don't split into separate trades for separate platforms, HMRC's view is same vehicle + same driver + same skills + same regulatory framework = same trade. Some drivers MISTAKENLY think each platform needs separate SA registration, only one is needed (your single self-employed trade as a driver).
    Can I claim the cost of replacing my taxi vehicle if I trade up?+
    Depends on capital allowance method + vehicle type. Cars (any vehicle classed as a car for tax purposes, most taxis including London black cab unless specifically classified as a hackney carriage commercial vehicle): NOT AIA-eligible; subject to Writing Down Allowance (WDA) at 18% main pool or 6% special rate pool depending on emissions. Commercial vehicles (vans, MPVs configured as commercial, rare in taxi use): AIA-eligible up to £1,000,000. Trading up: dispose old car (balancing allowance/charge against tax-written-down value); buy new car (start its own capital allowance journey). EV taxi cars: 100% first-year allowance available for ZERO-EMISSION cars; substantial tax-efficiency for transitioning to electric taxi vehicle.
    Does the 24-month rule apply to taxi drivers?+
    Not in the same way as employed contractors. Taxi drivers have NO single workplace, each fare is a different journey + customer. The 'workplace' concept doesn't bite. Travel from home to your first fare of the day IS business travel (you're not commuting to a fixed workplace); travel between fares is also business travel; travel home at end of shift is business travel. Some London black cab drivers questioning whether the rank they sit at counts as a 'workplace', answer is no, ranks are public stopping places not employment premises. Mileage method (simplified or actual cost) covers all business travel; the 24-month rule doesn't constrain it.
