Mileage Invoice Template for England and Wales

A mileage invoice is a specialised billing document that allows you to claim reimbursement for business travel expenses in accordance with HMRC guidelines and UK tax law. This document provides a professional format for recording journey details, calculating mileage payments, and ensuring compliance with current legislation governing business expense claims in England and Wales.

When do you need this document?

You'll need a mileage invoice when claiming business travel expenses from clients or employers, particularly if you're a contractor, consultant, or self-employed professional who uses personal vehicles for business purposes. This document is essential when you need to demonstrate compliance with HMRC's Approved Mileage Allowance Payments (AMAPs) system, which sets specific rates for different types of vehicles. You should also use this template when your business relationship requires formal invoicing procedures, when maintaining records for tax purposes, or when dealing with VAT-registered businesses that require detailed invoice documentation for their own compliance obligations.

Key legal considerations

The most critical aspect of mileage invoicing is adherence to HMRC's approved rates, which are currently 45p per mile for the first 10,000 business miles per tax year, and 25p per mile thereafter for cars and vans. Your invoice must clearly distinguish between business and personal mileage, as only genuine business travel qualifies for tax relief. You're required to maintain accurate records of journey purposes, dates, start and end locations, and total distances travelled. If your business is VAT registered, your mileage invoice must include appropriate VAT information and comply with VAT invoicing requirements. Additionally, you must ensure that all personal data included in the invoice is handled in accordance with UK GDPR requirements, particularly when sharing client information or journey details that could identify individuals or locations.

Legal requirements in England and Wales

Under the Income Tax (Earnings and Pensions) Act 2003, mileage payments that exceed HMRC's approved rates become taxable benefits, making accurate calculation essential for both tax compliance and avoiding unexpected liabilities. The Companies Act 2006 requires businesses to maintain proper financial records, including mileage claims, for at least six years. If you're VAT registered, the Value Added Tax Act 1994 mandates that your invoices contain specific information including your VAT number, invoice date, and clear description of services provided. Your mileage records may be subject to HMRC inspection, so you must be able to demonstrate that all claimed journeys were genuinely for business purposes. The invoice should include sufficient detail to satisfy HMRC's record-keeping requirements while protecting any sensitive information about clients or business activities in compliance with data protection legislation.
