> Quick answer: UK employers reimburse business mileage using HMRC Approved Mileage Allowance Payments (AMAP)—45p per mile for the first 10,000 business miles and 25p per mile thereafter in 2026—without the employee incurring tax if paid at or below AMAP. GPS-verified mileage logs satisfy HMRC's contemporaneous record requirement for both employers and self-employed claimants.
UK HMRC mileage framework overview
Her Majesty's Revenue and Customs (HMRC) governs how UK employers reimburse employees who use personal vehicles for business travel. Unlike US states with wage-and-hour reimbursement mandates, UK mileage is primarily a tax compliance matter: payments within AMAP limits are tax-free; amounts above AMAP are taxable earnings unless the employee can demonstrate higher actual costs and claims tax relief.
Field sales teams, community nurses, social workers, utility inspectors, and tradespeople who drive between assignments need systems that produce HMRC-defensible mileage records. Manual spreadsheets fail audits because HMRC requires contemporaneous logs showing date, destination, purpose, and miles.
HMRC Approved Mileage Allowance Payments (AMAP) 2026
| Vehicle type | First 10,000 business miles | Miles above 10,000 |
|---|---|---|
| Cars and vans | 45p per mile | 25p per mile |
| Motorcycles | 24p per mile | 24p per mile |
| Bicycles | 20p per mile | 20p per mile |
AMAP covers the full cost of owning and running the vehicle for business purposes—fuel, insurance, servicing, depreciation. Employers paying at or below AMAP do not report the payment as taxable income and do not pay Class 1 NICs on the reimbursement (subject to qualifying conditions).
Advisory Fuel Rates (company cars)
HMRC advisory fuel rates Employers providing company cars with fuel cards use HMRC **advisory fuel rates** for reimbursement when employees repay private fuel, or for mileage claims in company cars where AMAP does not apply. HMRC updates these quarterly based on fuel prices. Check for current pence-per-mile figures by engine size.
Legal requirements table — UK employers
| Topic | UK rule |
|---|---|
| Tax-free reimbursement ceiling | AMAP rates (45p/25p per mile for cars) |
| Record keeping | Contemporaneous mileage log with date, destination, purpose |
| National Minimum Wage interaction | Business mileage reimbursement does not count toward NMW if it reflects actual business travel costs |
| GDPR / UK GDPR | Location data is personal data; lawful basis and transparency required |
| IR35 / employment status | Reimbursement policies must apply consistently to employees and not substitute for disguised remuneration |
| Penalty exposure | HMRC penalties for inaccurate records; employment tribunal for unlawful wage deductions if policies breach contracts |
GPS employee tracking compliance in the UK
UK GDPR and the Data Protection Act 2018 classify GPS location data from employee devices as personal data. Employers must:
1. Identify a lawful basis — typically legitimate interests (workforce management, mileage verification) with documented balancing tests, or contractual necessity.
2. Provide privacy notices — explain what location data is collected, when tracking activates, retention periods, and employee rights.
3. Apply data minimisation — shift-session GPS that captures trips during working hours is more defensible than 24/7 monitoring.
4. Enable subject access requests — employees can request copies of their location records.
5. Conduct DPIAs for large-scale or intrusive monitoring — ICO guidance recommends Data Protection Impact Assessments for workforce tracking.
The Information Commissioner's Office (ICO) Employment Practices Code emphasises transparency. Covert GPS tracking without notice is likely unlawful except in narrow fraud investigations with proper governance.

Mileage reimbursement requirements and record keeping
HMRC expects employees and employers to maintain records made at or near the time of travel. Acceptable evidence includes:
- Date of journey
- Start and end locations (postcode or address)
- Business purpose (client name, site reference)
- Miles driven (road distance, not straight-line)
- Vehicle type
GPS mileage systems that timestamp route points during shift sessions produce stronger audit trails than retrospective estimates. For self-employed sole traders, the same records support Self Assessment mileage claims.
Employer obligations checklist — UK

Frequently asked questions — UK HMRC mileage
What is the HMRC mileage rate for 2026?
HMRC AMAP rates remain 45p per mile for the first 10,000 business miles and 25p per mile thereafter for cars and vans. Motorcycles receive 24p and bicycles 20p per mile.
Is GPS mileage acceptable to HMRC?
Yes. HMRC requires contemporaneous records; GPS logs with timestamps, destinations, and business purposes satisfy this standard when retained and produced on request.
Do UK employers have to reimburse mileage?
There is no universal legal mandate to reimburse at a specific rate, but employment contracts, National Minimum Wage rules, and industry practice create strong expectations. AMAP provides the tax-free framework when employers do reimburse.
Is GPS employee tracking legal in the UK?
Yes, with UK GDPR compliance: lawful basis, transparency, data minimisation, and shift-session limits. Covert tracking risks ICO enforcement.
What happens if employers pay above AMAP?
Amounts above AMAP are taxable earnings unless the employee claims tax relief for actual costs exceeding AMAP on their Self Assessment.
Cross-border and multi-entity considerations
UK-headquartered enterprises with field staff in Scotland, Wales, and Northern Ireland apply the same HMRC AMAP framework UK-wide, but Scottish and Welsh minimum wage and employment tribunal venues differ from England. Employers with EU subsidiaries must not assume AMAP rates satisfy German or French tax rules for employees driving abroad—configure territory-specific rates per jurisdiction.

Implementation roadmap for HR and accounts teams
Rolling out compliant mileage reimbursement and GPS tracking requires coordinated steps across HR, legal, accounts, and IT:
1. Policy draft — Publish written travel and mileage rules specifying eligible trips, excluded commuting, reimbursement rate methodology, and GPS monitoring scope.
2. Privacy review — Legal/compliance reviews location data flows, retention, subprocessors, and employee notice language before app deployment.
3. Rate configuration — Accounts configures territory-specific per-mile or per-km tables matching tax authority benchmarks for each operating jurisdiction.
4. Pilot cohort — Test with a single field team region; validate GPS accuracy on representative routes before enterprise rollout.
5. Payroll integration — Map reimbursement export format to payroll cycles; separate taxable vs. non-taxable components.
6. Manager training — Teach supervisors to approve trips based on verified distance, not employee estimates.
7. Annual review — Reconcile rates against tax authority updates each January; validate car allowances against actual employee cost surveys.
Common audit triggers and mistakes
Auditors and regulators typically challenge: (1) missing business purpose on trip logs, (2) commuting miles incorrectly included, (3) round-number estimates without route evidence, (4) GPS data retained without access controls, and (5) reimbursement rates not updated when tax authorities publish new benchmarks. Automated GPS mileage systems address triggers (1)–(3); role-based access and retention policies address (4); territory rate tables address (5).
Enterprises operating across multiple countries should maintain a compliance matrix mapping each territory's per-mile/km rate, per diem meal scales, GPS privacy obligations, and record retention periods—updated annually when finance publishes new tax authority schedules. Field operations directors should review this matrix each quarter alongside fuel price trends.
