This guide outlines the UK tax rules for deducting or reimbursing employee travel and subsistence expenses, based on legislation and HMRC guidance. These rules apply to employees and directors.

Qualifying for Tax Relief on Travel Expenses

For an employee to claim a deduction for travel expenses, the costs must meet specific statutory conditions. The two main rules for travel expenses are:

1. Travel in the Performance of Duties: A deduction is allowed if the employee is required to incur and pay travel expenses while actually performing their job duties. The key condition is that the expenses must be “necessarily incurred”. This covers employees with “travelling appointments” whose work inherently involves travel (e.g., a service engineer who travels from one client site to another).

1. Travel for Necessary Attendance: A deduction is allowed for expenses attributable to an employee’s “necessary attendance” at any place to perform their duties. However, this rule explicitly excludes the costs of “ordinary commuting” or “private travel”.

Permanent vs. Temporary Workplaces

The ability to claim for travel to a workplace depends heavily on whether it is a “permanent” or “temporary” workplace.

• Workplace: A place where the employee’s attendance is necessary to perform their duties.
• Ordinary Commuting: Travel between an employee’s home and a permanent workplace is considered ordinary commuting, and the costs are not deductible.
• Permanent Workplace: A place the employee attends regularly for their job, which is not a temporary workplace. A location can also be deemed a permanent workplace if it is the base from which duties are performed or where tasks are allocated.
• Temporary Workplace: A place an employee attends to perform a task of limited duration or for another temporary purpose. Travel from home to a temporary workplace is generally allowable.

Key Limitations for Temporary Workplaces:

• The 24-Month Rule: A workplace is not considered temporary if the employee attends it for a continuous period of work lasting more than 24 months, or if it is expected to last that long. In such cases, it becomes a permanent workplace, and travel to it is treated as ordinary commuting.
• Fixed-Term Appointments: If an employee attends a workplace for a period that is expected to comprise all or almost all of their employment period, that workplace is considered permanent, regardless of its duration.

Accommodation and Subsistence Costs

The term “travel expenses” includes more than just the cost of a ticket. It can cover:

• The actual cost of travel (e.g., train fares, flights).
• Necessary subsistence costs incurred during the journey, such as meals.
• The cost of accommodation and necessary meals where an overnight stay is required for business.
• Other associated costs, such as utility bills for temporary accommodation.

A deduction is only allowed for subsistence costs that are additional to what the employee would normally incur if not on a business trip. For example, the cost of a sandwich bought at a train station during a business journey is allowable, but a sandwich made at home and eaten on the journey is not, as the cost was not incurred during the travel.

Regarding set rates for meals, HMRC guidance notes that there are no generally applicable authorized subsistence rates. Employers may agree on bespoke scale rates with HMRC for their employees.

For overnight stays, employers can also make tax-free payments for incidental expenses (e.g., laundry, phone calls home) up to statutory limits.

Specific Travel Scenarios

The legislation provides for several other specific situations:

• Travel Between Group Employments: A deduction is allowed for travel between workplaces of two different companies within the same group (a company and its 51% subsidiaries).
• Travel for Overseas Employment: UK resident employees whose duties are performed wholly outside the UK can receive a deduction for the costs of travelling from the UK to take up the job and for returning to the UK when it ends.
• Workers Provided via Intermediaries: Special rules apply to workers who provide their services to a client through an intermediary, such as a personal service company. If the worker is subject to (or the right of) supervision, direction, or control, each engagement with a client is treated as a separate employment. This generally prevents the worker from claiming relief for home-to-work travel and subsistence costs, as the client’s site is treated as a permanent workplace for that engagement.

Compliance and Record-Keeping

To claim a deduction or receive tax-free reimbursement, it is essential to prove that the expenses were incurred and meet the relevant conditions. While the sources do not specify a retention period, keeping detailed records, including journey logs and receipts, is crucial to substantiate any claim. If an employer reimburses an employee for more than the amount allowable for tax purposes, the excess may be treated as taxable earnings.

When a UK limited company acquires a car for business use, the decision to either lease or buy the vehicle has distinct consequences for the company’s tax position. The treatment for Corporation Tax and Value Added Tax (VAT) is governed by a specific set of rules that depend on factors such as the car’s CO2 emissions, its use for business and private journeys, and whether the company owns the asset or pays rentals.

Leasing a Car Through a Limited Company

Leasing typically involves a contract hire agreement where the company makes regular rental payments for the use of the car, which remains owned by the leasing company (the lessor).

Corporation Tax Relief on Lease Rentals

Lease rental payments are generally treated as a revenue expense and can be deducted from the company’s profits, thereby reducing its Corporation Tax liability. However, a restriction applies to the deduction of hire costs for certain cars.

• Cars with CO2 emissions over 50g/km: For leases entered into from April 2021, if a car’s CO2 emissions exceed 50g/km, a 15% restriction applies. This means only 85% of the car hire costs are allowable as a deduction for Corporation Tax purposes.
• Cars with CO2 emissions of 50g/km or less: If the car’s CO2 emissions are 50g/km or less, 100% of the lease rental payments are deductible against profits, subject to the costs being incurred for business use.

VAT on Lease Rentals

If the company is VAT-registered and leases a ‘qualifying car’ that is used for business purposes, the treatment of VAT on the lease payments is subject to a specific block if the car is available for private use.

• The 50% Input Tax Block: A business leasing a car that is available for any private use cannot normally recover 50% of the VAT charged on the lease rentals. This is known as the ‘50% block’ and acts as a proxy for the tax on private use. The remaining 50% of the VAT can be reclaimed, subject to the normal rules for input tax recovery. This block applies to all charges under the leasing agreement, including optional services unless they are supplied and invoiced separately.
• Exceptions to the 50% Block: A business can reclaim 100% of the VAT on lease charges if the car is a qualifying car and is used primarily for specific qualifying purposes, such as a taxi for carrying passengers or for providing driving instruction. The 50% block also does not apply if a car is hired for no more than 10 days specifically for business purposes, provided it is not a replacement for an ordinary company car.

Ongoing Motoring Costs

VAT incurred on repairs and maintenance can be reclaimed in full as input tax, provided the business paid for the work and the vehicle is used for business purposes. This is the case even if the vehicle is also used for private motoring.

Buying a Car Through a Limited Company

When a company buys a car, it can claim capital allowances to deduct a portion of the vehicle’s value from its profits over time. Cars do not qualify for the Annual Investment Allowance (AIA).

Capital Allowances

The rate of capital allowances a company can claim depends on the car’s CO2 emissions and whether it is new or second-hand. For cars purchased from April 2021 onwards, the following rules apply:

• 100% First-Year Allowance (FYA): A company can deduct the full cost of a new and unused car from its profits in the year of purchase if the car has CO2 emissions of 0g/km (i.e., it is an electric car).
• Writing-Down Allowances (WDA): For other cars, WDAs are claimed annually on the reducing balance of the cost. The expenditure is allocated to one of two pools:
• Main Rate Pool (18% WDA): Expenditure on cars with CO2 emissions of 50g/km or less is allocated to the main rate pool, which has a WDA rate of 18% per annum. This also applies to second-hand electric cars.
• Special Rate Pool (6% WDA): Expenditure on cars with CO2 emissions exceeding 50g/km is allocated to the special rate pool, which has a WDA rate of 6% per annum.

If the balance in either the main or special rate pool is £1,000 or less before calculating WDA for the period, the entire remaining balance can be written off as a small pools allowance.

VAT on Car Purchase

The rules for reclaiming VAT on the purchase of a car are highly restrictive.

• General Rule (100% Input Tax Block): As a general rule, a business cannot recover the VAT on the purchase of a car. This is a complete block on input tax recovery.
• Exceptions to the Block: A business can recover 100% of the VAT on a car purchase only in very specific circumstances, for instance, if the car is:
• To be used exclusively for business purposes and is not available for private use. A “pool car” that is kept at the business premises and not allocated to a single individual typically meets this condition.
• Intended to be used primarily as a taxi, for driving instruction, or for self-drive hire.
• A stock-in-trade vehicle for a motor dealer.

If VAT is recovered in full under one of these exceptions and the car’s use later changes to a non-qualifying purpose (e.g., a pool car is allocated to an employee for private use), the business must account for a “self-supply” and pay output tax based on the car’s value at that time.

When deciding between providing a company car or having a director use their personal vehicle for business, UK companies and their directors must consider the tax implications, administrative requirements, and the nature of the vehicle itself. The tax landscape for 2026/2027 continues to heavily favour certain types of vehicles over others, making a careful analysis essential.

This guide breaks down the rules for both options, incorporating corrections based on current tax legislation and HMRC guidance.

Company Car Tax Mechanics

Providing a director with a car that is available for private use creates a taxable Benefit-in-Kind (BIK). The tax liabilities for both the director and the company are calculated based on this BIK value.

Benefit-in-Kind (BIK) Calculation

The BIK value is determined by multiplying the car’s list price (its P11D value) by a specific percentage, which is primarily based on the car’s carbon dioxide (CO2) emissions.

• Director’s Tax: The director pays income tax on the BIK value at their marginal rate (e.g., 20%, 40%, or 45% in England and Northern Ireland for the 2025/26 tax year).
• Company’s Tax: The company is liable for Class 1A National Insurance Contributions (NICs) on the same BIK value. The Class 1A NIC rate for the 2025/2026 tax year is 15% .

Note: The following analysis will proceed based on the general principles and available data, but confirmation of the exact BIK rates for 2026/2027 would be required.

Private Fuel Benefit

If the company also pays for the director’s private fuel, a separate fuel benefit charge arises. This is calculated by applying the same BIK percentage to a fixed figure set by HMRC for the relevant tax year. The resulting amount is also subject to income tax for the director and Class 1A NICs for the company. The sources provided do not contain the fuel benefit charge multiplier for the 2026/2027 tax year.

Company Relief: Capital Allowances

A company purchasing a car can claim capital allowances to deduct the cost from its taxable profits. The type and rate of these allowances are strictly determined by the car’s CO2 emissions.

100% First-Year Allowance (FYA)

A 100% FYA allows the company to deduct the full cost of the asset in the year of purchase. This is a significant tax incentive, but it is narrowly defined for cars.

• Eligibility: Under Section 45D of the Capital Allowances Act 2001 (CAA 2001), the 100% FYA is only available for expenditure on a new and unused car that is either electrically-propelled or has CO2 emissions of 0g/km.
• Correction – No FYA for Hybrids: Contrary to the suggestion in your article, hybrid cars do not qualify for the 100% FYA, as their CO2 emissions are greater than 0g/km.
• Time Limit: This allowance is available for qualifying expenditure incurred up to 31 March 2026 for companies subject to Corporation Tax.

Writing Down Allowances (WDA)

Cars that do not qualify for the 100% FYA are allocated to a capital allowances pool and receive WDAs on a reducing balance basis each year. The applicable pool and rate depend on the car’s CO2 emissions.

• Main Rate Pool (18% WDA): For cars with CO2 emissions between 1g/km and 50g/km.
• Special Rate Pool (6% WDA): For cars with CO2 emissions exceeding 50g/km.

The 18% rate applies to the main rate pool, while the special rate pool has a lower WDA of 6%.

Leasing a Company Car

If a company leases a car rather than buying it, it cannot claim capital allowances. Instead, the lease rental payments are treated as a business expense.

• Deductibility: The full rental cost is normally deductible from the company’s profits.
• Lease Rental Restriction: However, if the CO2 emissions of the leased car exceed 50g/km, a 15% restriction applies. This means the company can only deduct 85% of the rental payments for tax purposes.

Personal Car Tax Mechanics

If a director uses their own car for business journeys, the company can reimburse them for the mileage. This system avoids BIK charges entirely.

Mileage Allowance Payments (MAPs)

Companies can make tax-free payments to directors for business mileage up to a certain approved amount. For the 2025/2026 tax year, the rates for cars and vans are:

• 45p per mile for the first 10,000 business miles in the tax year.
• 25p per mile for each business mile thereafter.

These payments are received tax-free by the director and are a fully deductible expense for the company, reducing its Corporation Tax liability.

Record Keeping

HMRC requires detailed and accurate records of all business journeys for which mileage is claimed. This includes the date, purpose, start and end points, and the number of miles for each trip. Failure to keep adequate records or making inaccurate claims can lead to HMRC compliance checks and penalties for inaccuracies in a tax return or other document.

Correct Scenarios for Directors

Based on this analysis, the strategic choice for directors in 2026/2027 is as follows:

• High-Mileage, Zero-Emission EV Driver: The company car route is highly attractive. The company can benefit from the 100% FYA (if purchased before 31 March 2026), and the director benefits from a low BIK rate. The company can also deduct all running costs (insurance, servicing, repairs). This combination often proves more tax-efficient than mileage claims for high-mileage drivers.

• Hybrid or High-Emission Petrol/Diesel User: The personal car route is often more favourable.
• Company Car Downsides: A company-owned hybrid or petrol/diesel car will attract a much higher BIK charge for the director. The company will not get the 100% FYA and will instead receive much slower tax relief through 18% or 6% WDAs. If leased, cars with emissions over 50g/km will have their rental deductions restricted.
• Personal Car Advantages: Using a personal car and claiming mileage avoids the high BIK charges entirely. While the director bears the running costs personally, the tax-free mileage reimbursement provides a simple and often more tax-efficient alternative.

• Low-Mileage Driver (Any Vehicle): For directors who travel very few business miles, the personal car option is typically better. The BIK tax on even a low-emission company car can easily exceed the value of tax-free mileage payments for low annual business mileage.

For directors of limited companies, employer pension contributions represent a highly tax-efficient method of profit extraction. When structured correctly, these contributions can provide significant tax relief for the company while forming a key part of a director’s personal remuneration and retirement strategy.

Corporation Tax Deductibility

A pension contribution made by an employer to a registered pension scheme for a director is generally an allowable expense, deductible against the company’s profits for Corporation Tax purposes. However, this deduction is contingent on the contribution satisfying the ‘wholly and exclusively’ test, meaning it must be made solely for the purposes of the company’s trade.

For a director who is also a shareholder of a close company, HMRC guidance stipulates that the entire remuneration package-which includes salary, bonuses, benefits, and pension contributions-must be considered. The total package must be commercially reasonable for the value of the work the director undertakes. If the overall remuneration is deemed excessive, HMRC may challenge the deductibility of the pension contribution, in part or in full, on the grounds that it was not paid wholly and exclusively for the purposes of the trade. To assess whether a remuneration package is reasonable, HMRC may compare it with packages paid to unconnected employees performing duties of similar value. In the absence of a suitable comparator, general principles regarding remuneration for directors and their relatives will be applied. It is therefore crucial for companies to be able to justify the commercial basis for a director’s entire remuneration package.

Tax Treatment for the Director and the Pension Fund

On Contribution: A significant advantage of employer pension contributions is that they are not treated as a taxable benefit for the director. This means there is no liability to Income Tax or National Insurance contributions for the director at the point the contribution is made by the company.

Investment Growth: Once inside a registered pension scheme, the funds can grow in a tax-privileged environment. The tax rules provide for several important exemptions:

• Income derived from investments or deposits held by the scheme is exempt from Income Tax.
• Gains arising from the disposal of scheme investments are exempt from Capital Gains Tax.

Inheritance Tax (IHT): Successive governments have provided generous tax reliefs to encourage pension savings. While this often results in pension funds falling outside of a person’s estate for IHT purposes, this is not a total exemption. There are circumstances where IHT charges can arise on a pension scheme, contributions made to it, or payments from it.

Withdrawals from the Pension: Pension income, which includes payments from a scheme pension, lifetime annuity, or income withdrawal, is generally taxable on the individual receiving it in the tax year it accrues. The payer of the pension is required to operate the Pay As You Earn (PAYE) system on these payments.

Individuals can typically start accessing their pension funds from the normal minimum pension age. For the 2026/27 tax year, this age is 55. This age is scheduled to rise to 57 on and after 6 April 2028.

Pension Contribution Limits

• Annual Allowance: There is a limit on the total amount of contributions that can be made to an individual’s pension schemes in a tax year while still benefiting from tax relief. This is known as the annual allowance. If contributions exceed this allowance, an annual allowance charge may be payable by the individual. In certain circumstances, an individual can elect for the pension scheme to pay this charge on their behalf, which is known as ‘scheme pays’.

• Lifetime Allowance: The lifetime allowance charge was abolished with effect from 6 April 2024.

Comparing Remuneration Methods

When considering how to extract profits from a limited company, it is useful to compare the tax treatment of different methods:

• Employer Pension Contribution: This is generally a deductible expense for the company’s Corporation Tax calculation, provided the ‘wholly and exclusively’ test is met. The director does not pay Income Tax or National Insurance on the contribution. The funds grow largely tax-free within the pension, and tax is paid by the director upon withdrawal in retirement.

• Salary: This is also a deductible expense for Corporation Tax. However, the salary is subject to both employee’s and employer’s National Insurance contributions, as well as Income Tax for the director through PAYE.

• Dividends: These are paid to shareholders out of the company’s post-Corporation Tax profits and are therefore not deductible for Corporation Tax. The director-shareholder is then liable to pay dividend income tax on the amount received, although there is no National Insurance on dividend payments.

From a tax perspective, employer pension contributions are often the most efficient way to extract profit for retirement savings, as they attract Corporation Tax relief and avoid any immediate charge to Income Tax and National Insurance for the director. This contrasts with salary, which is subject to both IT and NI, and dividends, which are paid from profits that have already suffered Corporation Tax.
