Advisory Fuel Rates For Company Cars (Latest For 2025)

Last update: This post was updated with the latest mileage rates as of 1st March 2025.

The table below shows the latest HMRC advisory fuel rates for petrol and diesel cars. These are the suggested reimbursement rates for employees’ private mileage using their company car.

Where the employer does not pay for any fuel for the company car, these are the amounts that can be reimbursed in respect of business journeys without the amount being taxable on the employee.

Where there has been a change the previous rate is shown in brackets. If there has been a change in rates, you can continue to use the previous rates for up to one month from the effective date of the new rates.

Engine Size Petrol Diesel LPG
1,400cc or less 12p (12p) 11p (11p)
1,600cc or less 12p (11p)
1,401cc to 2,000cc 15p (14p) 13p (13p)
1,601cc to 2,000cc 13p (13p)
Over 2,000cc 23p (23p) 17p (17p) 21p (21p)

 

HMRC Advisory Fuel Rates For Hybrid & Electric Vehicles

For fully electric vehicles, the reimbursement rate is 7p per mile (previously 7p per mile). For hybrid cars, you should use the relevant petrol or diesel rate.

Tax-Free Reimbursement for Business Journeys

These fuel rates can be reimbursed by employers without any tax implications for the employee when no fuel is provided for the company car.

Reclaiming Input VAT on Fuel

Within the 45p/25p mileage payments, the amounts in the table above represent the fuel element. Employers can reclaim 20/120 of the reimbursed amount as input VAT, provided the claim is backed by a VAT invoice from the filling station.

For example, for a 2500cc petrol-engine car, 4 pence per mile can be reclaimed as input VAT (23p x 1/6).

Employees Using Their Own Cars for Business

For employees using their own vehicles for business purposes, the Advisory Mileage Allowance Payment (AMAP) continues to be 45p per mile for the first 10,000 business miles, reducing to 25p per mile thereafter. An additional 5p per passenger can be claimed when carrying fellow employees.

Importantly, for National Insurance contribution purposes, employers can continue to reimburse at the 45p rate regardless of the 10,000-mile threshold.

Year-End Tax Planning Ideas For Individuals & Businesses

It’s never too late to undertake some end-of-year tax planning.

Now is the perfect time to review your finances and make sure you’re making the most of available tax reliefs and allowances. A little planning now can help reduce your tax bill and keep more of your hard-earned money. Here’s a breakdown of key tax planning opportunities you should consider before 5th April 2025.

Year-End Tax Planning Ideas For Individuals

Max Out Your ISA

If you have some spare cash, an obvious tax planning point would be to maximise your ISA allowances.

Individual Savings Accounts (ISAs) remain one of the most tax-efficient ways to save and invest. For the 2024/25 tax year, the ISA allowance is £20,000 per person. By using your full allowance, you can protect your savings and investments from income tax and capital gains tax (CGT).

Set Up A Lifetime ISA (LISA) To Save

If you’re aged between 18 and 39, you can also set up a Lifetime ISA to help buy your first home or save for later life – but you must make your first contribution before turning 40.

You can contribute up to £4,000 each year until you’re 50. The government will add a 25% bonus to your savings, up to a maximum of £1,000 per year. Note that the Lifetime ISA limit of £4,000 counts towards your £20,000 annual ISA limit.

You can withdraw money from your LISA if you’re:

  • Buying your first home, or;
  • Aged 60 or over, or;
  • Terminally ill, with less than 12 months to live.

However, if you withdraw cash or assets for any other reason (an unauthorised withdrawal), you’ll pay a withdrawal charge of 25%. This recovers the government bonus you received on your original savings.

Boost Your Pension

You might also want to consider increasing your pension savings before the end of the tax year (5th April, every year).

Under the current rules, the government provides tax relief at your highest rate of tax:

  • Basic rate taxpayers (20%): Contributing £4,000 results in an actual cost of £3,200 (as the government tops it up to £5,000).
  • Higher rate taxpayers (40%): Can claim an additional £1,000 relief, bringing the net cost down to £3,000.
  • Additional rate taxpayers (45%): Receive even more tax relief, reducing the net cost further.

Additional pension contributions can be even more effective if your income is over £100,000, as you start to lose your £12,570 personal allowance. For every £2 earned above this threshold, your allowance reduces by £1, disappearing completely at £125,140. However, making pension contributions can help you bring your taxable income below this threshold, effectively providing a 60% tax saving.

And if you’re wondering how much you can contribute to your pension, then here’s what you need to know: for most UK taxpayers, the maximum annual pension contribution allowance is currently £60,000 per tax year (this can be reduced for higher earners due to the tapered annual allowance rules). This limit includes total contributions from both you and your employer. You can carry forward unused allowances from the previous three tax years, allowing you to exceed the £60,000 limit in the current year if previous allowances remain unused. For example, any unused allowance from the 2021/2022 tax year must be utilised by 5th April 2025 or it will expire.

Bring Forward Your Capital Gains

Capital Gains Tax (CGT) is a tax on any profit you make on the disposal of an asset and it applies to most assets when they’re sold. However, there are some exceptions. For example, you don’t pay CGT when you sell your main residence, or on personal possessions sold for less than £6,000.

If you have unrealised gains, then you might wish to consider bringing them forward if you haven’t used your Annual Exempt Amount, which is £3,000 for gains from the 2024/2025 tax year. It was previously as high as £12,000 a few years ago, so the allowance has been reduced significantly. Nonetheless, you should still make the most of it as part of your year-end tax planning.

Also, consider if you have any worthless shares for a negligible value claim to establish a capital loss. You may even be able to set off that capital loss against your income under certain circumstances which could save tax of up to 45% of the loss.

Get in touch with our capital gains tax advisors if you have any questions or require further support in this area.

Use Your Gift Allowance

Looking to start passing on your wealth and assets without incurring an inheritance tax bill?

It may be worth utilising the annual exemption for gifts, which currently stands at £3,000. Plus, if you didn’t use up the gift allowance in the previous tax year, then it can carry over. Note that £3,000 is the total allowance for the tax year, not the amount for each gift.

There’s also an exemption from inheritance tax for regular gifts out of an individual’s surplus income. Inheritance tax is designed to tax transfers of capital, so if the donor can demonstrate that the gifts are made out of surplus income then the transfers are not taken into consideration for IHT. The exemption applies where there is a regularity to the payments, such as a standing order to pay school fees or pension contributions on behalf of children or grandchildren. HMRC will also require proof that the payments are paid out of post-tax income and do not limit the donor’s normal lifestyle. Detailed records are required, and we can help you with a suitable spreadsheet

Take Dividends

The Dividend Allowance remains at £500 for 2024/25. If you own a limited company, consider taking dividends before the tax year-end to optimise your income strategy.

Gift Aid Donations

If you’re feeling charitable, making Gift Aid donations before the tax year-end can reduce your tax bill. Higher and additional rate taxpayers can claim back tax relief on their self-assessment tax return, lowering their tax liability further.

Year-End Tax Planning Ideas For Businesses

It is always a good idea to set up a planning meeting with us a couple of months before your business year-end so that we can advise you on the best actions to take to reduce your taxable profits. In addition to considering paying yourself a bonus from your company you might consider the following…

Annual Investment Allowance (AIA)

If you are thinking of investing in your business, e.g. new vans, plant and machinery, equipment, and even IT systems, then you may wish to do so before the year-end to get tax relief this year rather than wait another year.

The Annual Investment Allowance (AIA) allows businesses to claim 100% tax relief on up to £1 million spent on qualifying assets.

Motor vehicles are excluded, but businesses purchasing a new, zero-emissions electric car can claim 100% first-year capital allowances.

Full Expensing For Limited Companies

If you run a limited company, you can claim full expensing relief on new (not second-hand) plant and machinery purchases. Unlike AIA, there is no upper limit on qualifying expenditure.

Hire Purchase Agreements & Tax Relief

If your business buys equipment under a hire purchase agreement, you can still claim capital allowances on the full cost as long as the asset is in use before your business year-end – even if payments are spread over time.

Bring Forward Expenses

If you’re self-employed, there are additional tax planning opportunities, such as bringing forward expenses into this tax year or deferring income to manage tax liabilities efficiently. We can help you optimise your tax position.

Employer Pension Contributions

Pension contributions made to employees by an employer are tax-efficient. If you are considering making employer company pension contributions, you will need to make the payment before the year-end to get tax relief in the year. There are annual and lifetime limits to consider so it’s worth having a chat with your accountant before making payments.

Staff Bonuses

If you are considering staff bonuses for the year, then you may wish to make a note of the decision before the year-end and then you have up to 9 months to make the payment afterwards, but an accrual may be made before the year-end to get tax relief early.

Electric Company Cars

Have you considered electric cars for your business?

The advantages include:

  • 100% First Year Allowance at present against business profits e.g. an electric car purchased for £80,000 would save corporation tax at 19% i.e. £15,200 in the year of purchase.
  • Low benefit in kind rates:
    • 2024-25 – 2%
    • 2025-26 – 3%
    • 2026-27 – 4%
    • 2027-28 – 5%
  • Reduced Employer Class 1A National Insurance Contributions (company cars only).
  • Exemption from London Congestion Charge.
  • Significant fuel savings vs a comparable combustion engine car and no car fuel benefit for company cars.
  • The provision of free electric charging facilities for electric or plug-in hybrid cars will be a tax free benefit in kind, provided it is made available for all employees at that workplace.

Tax Relief For Staff Parties & Annual Functions

Planning a staff party is a great way to reward employees, boost morale, and encourage team bonding. But did you know that certain staff events, including Christmas parties and summer gatherings, can qualify for tax relief?

In this guide, we’ll break down the rules for tax-free staff events, so your business can make the most of these exemptions while staying compliant with HMRC.

Tax relief for staff parties – the rules

HMRC provides an exemption for annual staff functions, allowing businesses to claim tax relief and avoid benefit-in-kind charges, provided specific conditions are met:

  • The event must be annual (such as a Christmas party or a summer barbecue)
  • It must be open to all employees (or all employees at a particular location)
  • The event is not just to be for directors unless all your staff are directors
  • The cost must not exceed £150 per head, including VAT, for the tax year
  • The £150 allowance covers all associated costs, including food, drinks, venue hire, transport, and accommodation
  • If multiple events are held, the exemption applies only if the combined cost remains within the £150 limit

If these conditions are not met, the full cost of the event may be considered a taxable benefit for employees, which means additional tax liabilities.

Christmas parties and other year-round events

Christmas parties are a popular way for businesses to celebrate the end of the year, and they typically qualify for tax relief under the above rules. However, businesses can also take advantage of the exemption for other events, such as:

  • Summer barbecues
  • Team-building retreats
  • Annual award ceremonies

The key is that the total cost must not exceed the annual event allowance of £150 per head. Provided the threshold is not exceeded, there can be any number of parties. For instance, 3 parties at a cost of £50 each, at various times of the year.

That means, if you’ve already held a Christmas party then you can still host another event and both can be exempt from tax, provided the combined cost per head for the year does not exceed £150. If the combined cost exceeds this limit, the employer can choose which event to apply the exemption to for optimal tax benefits.

Example Scenario

  1. Your business hosts a Christmas Party. The cost per head is £100.
  2. Your business then hosts a summer barbecue. The cost per head is £70.

In this case, you can nominate the Christmas party for the exemption, making the £70 Summer Barbecue taxable. However, as the employer, you can manage the tax and National Insurance on behalf of the employees through a PAYE settlement agreement, avoiding direct tax implications for the employees.

How to calculate the cost per head

To calculate the cost of the benefit:

  1. Add together the cost of the party or function (room hire, food, entertainment, prizes, etc), the costs of transporting staff and their guests, and the cost of any accommodation provided.
  2. Divide the total by the number of persons (staff and any other guests) attending the function.
  3. The final sum is your cost per head. To qualify, the cost must come to less than or equal to £150 per head.

If you have a large function it may be impossible to count up exact numbers of those who physically attend (particularly if people come and go at different times). If it is impossible to work out actual attendees then you will have to estimate numbers according to what was budgeted or booked. Bookings are normally made on a ‘per head basis’.

What if the allowance is exceeded?

If the cost of an event exceeds £150 per head, the entire amount becomes a taxable benefit and must be reported on a P11D form. So, for example, if the cost per head works out at £152, then £152 is taxable as a Benefit In Kind and goes on your employees’ P11d, not £2.

Tax treatment for employer

The cost of the staff Christmas party (or any staff annual function) is tax-deductible in the employer’s accounts. Show this expense separately in the accounts as it is a staff benefit and therefore a cost of ‘staff welfare’ (or similar).

There is no monetary limit on the amount that an employer can spend on an annual function. A party costing more than £150 per head will be an allowable deduction in the employer’s accounts, as the employees would pay tax on a benefit at this level so it is just another form of earnings.

The full cost will be disallowed for tax if it is found that the entertainment of staff is, in fact, incidental to that of entertaining customers.

Parties covered by the £150 exemption do not have to be reported on form P11Ds. If you do exceed the limit and have created a taxable Benefit In Kind, you might consider settling it using a PAYE settlement agreement (you then pay your employees’ tax and NICs)

Can you reclaim VAT costs from staff parties?

If you’re wondering whether you can claim back the cost of input VAT from your staff parties, then you’ll be pleased to hear that you can. However, there are conditions to be aware of:

  • Input VAT is fully reclaimable on the cost of the function as it is “staff welfare” and not regarded by HMRC as entertaining, unless you are an owner-manager and having a one-man party, or if the function is mainly for directors (and so excluding other
    staff). In these circumstances, HMRC will block claims for input tax.
  • If you are also entertaining UK clients and staff, you have to disallow a proportion of input VAT (based on the number of clients vs staff).
  • If the event is to entertain UK customers and your staff are there to look after the customers, the whole event is regarded as “entertaining”. As such, you are blocked from any reclaim of input tax.
  • If the event also serves to entertain overseas customers then it may be possible to reclaim input VAT.

If you need advice, speak to one of our VAT specialists.

What about virtual parties?

HMRC has updated their guidance to include virtual annual functions within this exemption, which includes a virtual Christmas party. Virtual parties cannot have all employees in a single location so would ordinarily fail to qualify. HMRC’s revised guidance allows these events to qualify, provided that all of the other criteria are met.

A virtual party is defined as:

  • An annual function provided virtually using IT.

An example of this:

  • A company holds its annual function virtually using IT.
  • All employees are invited.
  • A hamper of food and drink is provided for each employee to enjoy during the party.
  • The total cost is £100 per head.

The cost is less than the £150 per head maximum and so the function is tax-exempt.
