UK Mileage Allowance: Tax Rules for Drivers

For many individuals across the United Kingdom who utilise their personal vehicles for business travel, understanding the intricacies of mileage allowance payments and their tax implications is paramount. This is particularly true for those in professions such as private hire or taxi driving, where personal vehicle usage for work is a daily reality. Navigating the rules set out by HM Revenue & Customs (HMRC) can seem daunting, but a clear grasp of concepts like Approved Mileage Allowance Payments (AMAP) and Mileage Allowance Relief (MAR) can significantly impact your take-home pay and ensure you remain compliant with tax regulations. This comprehensive guide aims to demystify these rules, providing clarity on when mileage payments are taxable, when they are not, and how you can claim relief.

Understanding Mileage Allowance Payments (MAPs)

At its core, a mileage allowance payment (MAP) is a sum paid by an employer to an employee for using their own private vehicle or bicycle for business-related travel. These payments are intended to cover the costs associated with running a vehicle, such as fuel, insurance, maintenance, and depreciation, which are incurred while performing duties for the employer. For an employee, particularly one operating a private hire vehicle, these costs can accumulate rapidly, making the proper handling of MAPs crucial for their financial well-being.

The rules governing the tax treatment of these payments underwent significant changes from 6 April 2002 onwards, simplifying the process for many. Prior to this date, the landscape was considerably more complex, often leading to payments being treated as taxable earnings unless specific conditions were met for a deduction. The introduction of the AMAP scheme aimed to streamline this, providing a clear framework for both employers and employees.

The Approved Mileage Allowance Payment (AMAP) Scheme

The cornerstone of current mileage allowance taxation is the Approved Mileage Allowance Payment (AMAP) scheme. From 6 April 2002, this scheme introduced a specific set of rates that employers can pay to employees for business travel using their own vehicle or bicycle without those payments being subject to tax. This means that if the payment you receive from your employer for business mileage does not exceed the AMAP limit, it is entirely tax-free.

HMRC sets the AMAP rates, and they are designed to cover the average cost of running a vehicle for business purposes. These rates can vary depending on the type of vehicle (e.g., car/van, motorcycle, bicycle) and the total business mileage covered in a tax year. While the precise rates are subject to change and are published by HMRC, the principle remains: up to the AMAP limit, payments are not considered taxable income.

For comprehensive details on the AMAP scheme, including the current rates and specific conditions, HMRC provides extensive guidance, notably at EIM31200 onwards in their Employment Income Manual. It is always advisable to consult the latest official guidance to ensure you are working with the most up-to-date figures.

What Happens When Payments Exceed the AMAP Limit?

While the AMAP scheme offers a generous tax-free threshold, it's important to understand the implications if your employer pays you more than the approved rates. If your mileage allowance payments exceeding the AMAP limit, the excess amount will be charged to tax. This means that only the portion of the payment that goes beyond the AMAP rate will be treated as taxable income and added to your earnings for tax purposes.

For example, if the AMAP rate for cars is 45p per mile for the first 10,000 miles, and your employer pays you 55p per mile, the extra 10p per mile will be subject to income tax and National Insurance contributions. This excess is typically reported by your employer via payroll and taxed accordingly, similar to your regular salary.

Additional Tax-Free Payments for Business Passengers

A notable benefit within the AMAP scheme, particularly relevant for private hire drivers or those who frequently transport colleagues, is the provision for additional tax-free payments when carrying business passengers. Employers can make further tax-free payments to employees who transport other employees in their own vehicle for business journeys. This is an extra allowance on top of the standard AMAP rate for the driver, acknowledging the additional wear and tear and costs associated with carrying passengers. This specific allowance is also covered within the AMAP guidance and is another avenue for tax-efficient reimbursement.

Mileage Allowance Relief (MAR): When Your Employer Pays Less Than AMAP

What if your employer pays you less than the AMAP rate, or perhaps doesn't pay any mileage allowance at all? This is a common scenario, and thankfully, HMRC provides a mechanism for employees to claim tax relief for the difference. This relief is known as Mileage Allowance Relief (MAR).

If your employer pays you less than the AMAP rate, you are entitled to claim tax relief against your earnings for the shortfall. This assumes, of course, that you earn enough to pay income tax in the first place. MAR allows you to effectively deduct the difference between the AMAP rate and what you were actually paid from your taxable income. For example, if the AMAP rate is 45p per mile and your employer only pays 25p per mile, you can claim tax relief on the remaining 20p per mile.

Claiming MAR typically involves either completing a self-assessment tax return if you already file one, or by submitting a P87 form to HMRC. The P87 form is specifically designed for employees to claim tax relief on job expenses, including mileage. Keeping accurate records of your business mileage is crucial for successfully claiming MAR.

Mileage Deductions and Universal Credit

For individuals receiving Universal Credit, the rules around mileage deductions also offer a beneficial provision. If you are an employee using your own vehicle for business travel and your employer pays less than the AMAP rate, you should be able to take a deduction from your income for benefits purposes. This means that the amount you could have received under AMAP (or the difference if your employer paid less) can be factored into your Universal Credit assessment, potentially increasing your entitlement. It's always wise to declare all relevant expenses when calculating income for benefits purposes to ensure you receive the correct amount.

The Legal Framework: Sections 62 and 72 ITEPA 2003

The legal basis for the taxation of employment income, including mileage allowance payments, is primarily found in the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003). Specifically, Sections 62 and 72 are highly relevant to this discussion.

• Section 62 ITEPA 2003: General Earnings
  This section broadly defines what constitutes "earnings" for tax purposes. Payments made by employers to employees in respect of travelling and related subsistence expenses *could* be taxable as earnings under Section 62. However, for mileage allowance payments from 2002-2003 onwards, the special rules of the AMAP scheme generally override this, meaning payments up to the AMAP limit are not earnings under S62.
• Section 72 ITEPA 2003: Payments Treated as Earnings
  More commonly, certain payments, particularly those for expenses, are *treated* as earnings by Section 72. This is often the case even if the payment does no more than reimburse a legitimate expense for which a deduction would otherwise be due (e.g., under Section 337, which allows deductions for expenses incurred wholly, exclusively, and necessarily in the performance of duties). So, while a payment might not be considered "earnings" under Section 62 because it's a direct reimbursement of an allowable cost, Section 72 can still bring it into charge as if it were earnings.

The distinction is important because if a payment for travelling expenses is considered earnings (either directly under S62 or treated as such by S72), the employee or director may then be entitled to claim a corresponding deduction under Section 337 (for travel in the performance of duties) or Section 338 (for ordinary commuting if it's "necessary" travel to a temporary workplace). This ensures that while the payment might initially be brought into charge, a matching deduction can effectively make it tax-neutral if the expense was genuinely incurred for business purposes.

For a comprehensive understanding of these rules, particularly regarding employee travel expenses and their deductibility, HMRC's guidance at EIM31800 onwards provides extensive detail.

Frequently Asked Questions (FAQs)

Navigating the complexities of mileage allowance and tax can lead to several common questions. Here, we address some of the most pertinent ones for employees, especially those who use their own vehicles for business, such as private hire drivers.

Q1: What are the current AMAP rates for cars/vans, motorcycles, and bicycles?

A1: While this article provides general guidance, the specific AMAP rates are subject to change and are published by HMRC. For the most up-to-date rates for cars/vans, motorcycles, and bicycles, you should always refer to the official HMRC website or their Employment Income Manual (EIM31200 onwards). These rates typically cover the first 10,000 business miles in a tax year, with a reduced rate applying thereafter for cars and vans.

Q2: How do I claim Mileage Allowance Relief (MAR) if my employer pays less than AMAP?

A2: If your employer pays you less than the AMAP rates, or nothing at all, you can claim tax relief for the difference. The most common ways to do this are:

• Online via a P87 form: If your expenses for the tax year are less than £2,500, you can use HMRC's online service to fill out a P87 form.
• By post using a P87 form: You can download and print a P87 form from the HMRC website and send it by post.
• Through your Self-Assessment tax return: If you already complete a Self-Assessment tax return (e.g., if you have other sources of untaxed income or are a higher-rate taxpayer), you can claim your mileage expenses directly on your return.

Remember to keep accurate records of your business mileage, including dates, destinations, and distances, as HMRC may request these as evidence for your claim.

Q3: Can I claim for carrying business passengers in my vehicle?

A3: Yes, under the AMAP scheme, employers can pay an additional tax-free allowance for each business passenger carried in your own vehicle on a business journey. This is separate from the mileage allowance paid to you as the driver. If your employer pays you this additional passenger allowance, it is tax-free. If they do not, or pay less than the approved passenger rate, you may be able to claim tax relief for the difference, similar to MAR for your own mileage.

Q4: Are these rules different for self-employed taxi drivers?

A4: This article primarily focuses on the rules for employees who use their own vehicles for business, such as private hire drivers employed by an operator. For self-employed taxi drivers (e.g., many black cab drivers or self-employed private hire drivers), the rules for claiming vehicle expenses are different. Self-employed individuals typically claim these costs as allowable business expenses against their profits for Self-Assessment purposes, rather than through the AMAP scheme or MAR. They can often claim a proportion of actual running costs (fuel, insurance, repairs, depreciation) or use simplified expenses (a flat rate per mile, similar in concept to AMAP but for self-employed).

Q5: What records should I keep to support my mileage claims?

A5: To support any mileage allowance relief claims or to justify tax-free payments from your employer, you should keep meticulous records. This includes:

• The date of each business journey.
• The start and end points of the journey.
• The reason for the journey (e.g., passenger pick-up, drop-off, maintenance, specific business meeting).
• The total number of business miles travelled for each journey.
• Records of any mileage allowance payments received from your employer.

Many digital apps and mileage trackers can help automate this process, ensuring accuracy and ease of record-keeping.

Conclusion

Understanding the tax implications of mileage allowance payments is essential for any employee who uses their own vehicle for business, particularly those in the taxi and private hire industry. The Approved Mileage Allowance Payment (AMAP) scheme provides a clear framework for tax-free reimbursements, while Mileage Allowance Relief (MAR) offers a vital safety net for those whose employers pay less than the approved rates. By grasping the principles outlined in Sections 62 and 72 of ITEPA 2003, and diligently keeping records, you can ensure you are correctly managing your tax affairs and maximising your legitimate expenses. Always refer to the latest HMRC guidance for the most current rates and detailed information, ensuring you are always compliant and financially optimised.
