This is the Finance Act 2017 version of this article. It is relevant for candidates sitting the Taxation – United Kingdom (TX-UK) (F6) exam in the period 1 June 2018 to 31 March 2019. Candidates sitting TX-UK (F6) after 31 March 2019 should refer to the Finance Act 2018 version of this article (to be published on the ACCA website in 2019).
From the September 2018 session, a new naming convention is being introduced for all of the exams in the ACCA Qualification, so from that session, the name of the exam will be Taxation – United Kingdom (TX-UK). June 2018 is the first session of a new exam year for tax, when the exam name continues to be F6 Taxation (UK). Since this name change takes place during the validity of this article, TX-UK (F6) has been used throughout.
Motor cars regularly feature in F6 (UK) exams, which is not surprising given that acquiring, running, or having the use of a motor car can have income tax, corporation tax, value added tax (VAT) or national insurance contribution (NIC) implications.
Purchasing a motor car
When a sole trader, partnership or limited company purchases a motor car, then capital allowances will be available. Motor cars do not qualify for the annual investment allowance, although new motor cars with CO₂ emissions up to 75 grams per kilometre qualify for a 100% first-year allowance.
Motor cars qualifying for writing down allowances at the rate of 18% (CO₂ emissions between 76 and 130 grams per kilometer) are included in the main pool, whilst motor cars qualifying for writing down allowances at the rate of 8% (CO₂ emissions over 130 grams per kilometer) are included in the special rate pool.
Newstart Ltd commenced trading on 1 April 2017. The following new motor cars were purchased during the year ended 31 March 2018:
|Date of purchase||Cost|
|CO₂ emission rate|
|Motor car (1)||3 April 2017||12,400||65 grams per kilometre|
|Motor car (2)||6 April 2017||17,700||110 grams per kilometre|
|Motor car (3)||8 April 2017||16,900||167 grams per kilometre|
The company’s capital allowances for the year ended 31 March 2018 are:
Motor car (2)
Motor car (3)
|WDA – 18%|
WDA – 8%
Motor car (1)
FYA – 100%
|WDV carried forward||14,514||15,548|
- Motor car (1) has CO₂ emissions up to 75 grams per kilometre and therefore qualifies for the 100% first year allowance.
- Motor car (2) has CO₂ emissions between 76 and 130 grams per kilometre and is therefore included in the main pool.
- Motor car (3) has CO₂ emissions over 130 grams per kilometre and is therefore included in the special rate pool.
There is no private use adjustment where a motor car is used by a director or an employee – an adjustment is only made where there is private use by a sole trader or a partner. Motor cars with private use are not pooled, but are kept separate so that the private use adjustment can be calculated.
Judith prepares accounts to 5 April. On 6 April 2017, the tax written down values of her plant and machinery were:
|Motor car (1)||15,600|
The following new motor cars were purchased during the year ended 5 April 2018:
|Date of purchase||Cost|
|CO₂ emission rate|
|Motor car (2)||1 May 2017||11,600||106 grams per kilometre|
|Motor car (3)||1 June 2017||16,400||114 grams per kilometre|
The following motor cars were sold during the year ended 5 April 2018:
|Date of sale||Proceeds|
|Motor car (1)||1 May 2016||13,400|
|Motor car (4)||1 June 2016||6,600|
Motor cars (1) and (2) were used by Judith, and 35% of the mileage was for private journeys. Motor cars (3) and (4) were used by an employee, and 10% of the mileage was for private journeys. The original cost of motor car (4) was £14,300, and this has previously been added to the main pool.
Judith’s capital allowance claim for the year ended 5 April 2018 is:
|WDV brought forward||36,700||15,600|
Motor car (2)
Motor car (3)
Motor car (1)
Motor car (4)
|Balancing allowance||(2,200)||x 65%||1,430|
|WDA – 18%|
WDA – 18%
|WDV carried forward||38,130||9,512|
- The private use of motor cars (3) and (4) is irrelevant, since such usage will be assessed on the employee as a taxable benefit.
- Note that with motor car (2), the full writing down allowance is deducted in calculating the written down value carried forward.
Where partners own their motor cars privately, it is the partnership (and not the individual partners) that make the capital allowances claim.
Auy and Bim commenced in partnership on 6 April 2017. The following new motor cars were purchased during the year ended 5 April 2018:
|Date of purchase||Cost|
|CO₂ emission rate|
|Motor car (1)||8 April 2017||11,400||59 grams per kilometre|
|Motor car (2)||10 April 2017||16,900||110 grams per kilometre|
Motor car (1) is used by Auy, and 40% of the mileage is for business journeys. Motor car (2) is used by Bim, and 85% of the mileage is for business journeys.
The partnership’s capital allowances for the year ended 5 April 2018 are:
|WDA – 18%||(3,042)||x 85%||2,586|
|Motor car (1)||11,400|
|FYA - 100%||(11,400)||x 40%||4,560|
|WDV carried forward||13,858|
Unless a motor car is used exclusively for business purposes, input VAT is not recoverable when it is purchased. Output VAT will then not be due on the disposal. Therefore, for capital allowance purposes, VAT inclusive figures are used.
Leasing a motor car
When calculating a business’s trading profit, no adjustment is necessary where the CO₂ emissions of a leased motor car do not exceed 130 grams per kilometre. Where CO₂ emissions are more than 130 grams per kilometre, then 15% of the leasing costs are disallowed in the calculation.
When calculating its trading profit for the year ended 31 March 2018, Fabio Ltd deducted the following leasing costs:
|Lease of motor car with CO₂ emissions of 150 grams per kilometre||3,280|
|Lease of motor car with CO₂ emissions of 105 grams per kilometre||2,980|
- The disallowance of leasing costs for the motor car with CO₂ emissions of 150 grams per kilometre is £492 (3,280 x 15%).
- There is no disallowance for the motor car with CO₂ emissions of 105 grams per kilometre, as this is less than 130 grams per kilometre.
Where a leased motor car is available for private use, then 50% of input VAT on leasing costs is non-deductible.
During the quarter ended 31 March 2018, Jimi, a sole trader, leased a motor car at a cost of £960 (inclusive of VAT). The motor car is used by Jimi and 70% of the mileage is for private journeys.
The motor car is available for private use, so £80 (960 x 20/120 x 50%) of the input VAT is non-deductible.
When calculating the trading profit for a sole trader or a partnership, an adjustment will be necessary for the private proportion of motor expenses that relate to the sole trader or the partners. No adjustment is necessary where motor expenses relate to directors or employees.
When calculating its trading profit for the year ended 5 April 2018, the partnership of Look & Hear deducted motor expenses of £4,100. This figure includes £2,600 in respect of the partners’ motor cars, with 30% of this amount being in respect of private journeys.
The disallowance for motor expenses is £780 (2,600 x 30%).
Provided there is some business use, the full amount of input VAT can be reclaimed in respect of repairs.
Where fuel is provided then all the input VAT (for both private and business mileage) can be recovered, but the private use element is then normally accounted for by way of an output VAT scale charge. The scale charge can apply to sole traders, partners, employees or directors.
Vanessa is self-employed, and has a motor car which is used 70% for business mileage. During the quarter ended 31 March 2018, Vanessa spent £1,128 on repairs to the motor car and £984 on fuel for both business and private mileage. The relevant quarterly scale charge is £492. All figures are inclusive of VAT.
Vanessa will include the following entries on her VAT return for the quarter ended 31 March 2018:
Fuel scale charge
(492 x 20/120)
(1,128 x 20/120)
Fuel (984 x 20/120)
However, if an employee or director is charged the full cost for the private fuel provided, output VAT will instead be calculated on this charge to the employee or director.
Ivy Ltd provides one of its directors with a company motor car which is used for both business and private mileage. For the quarter ended 31 March 2018, the total cost of petrol was £720, with the director being charged £216 for the private use element. Both figures are inclusive of VAT.
Ivy Ltd will include the following entries on its VAT return for the quarter ended 31 March 2018:
Charge to director
(216 x 20/120)
Fuel (720 x 20/120)
Provision of a company motor car
When an employee is provided with a company motor car, then the taxable benefit is calculated as a percentage of the motor car’s list price. The percentage is based on the level of the motor car’s carbon dioxide (CO₂) emissions.
List price: Any discounts given to the employer are ignored. The employee can reduce the figure on which his or her company car benefit is calculated by making a capital contribution of up to £5,000.
Percentage: The base percentage is 18%, and this applies where a motor car’s CO₂ emissions are at a base level of 95 grams per kilometre. The percentage is then increased in 1% steps for each five grams per kilometre above the base level, subject to a maximum percentage of 37%.
There are lower rates for company motor cars with low CO₂ emissions:
- For a motor car with a CO₂ emission rate of 50 grams per kilometre or less the percentage is 9%.
- For a motor car with a CO₂ emission rate of between 51 and 75 grams per kilometre the percentage is 13%.
- For a motor car with a CO2 emission rate of between 76 and 94 grams per kilometre the percentage is 17%.
Diesel cars: The percentage rates (including the lower rates of 9%, 13% and 17%) are increased by 3% for diesel cars, but not beyond the maximum percentage rate of 37%.
Reduction: The taxable benefit is proportionately reduced if a motor car is unavailable for part of the tax year.
Contribution: Any contribution made by an employee towards the use of a company motor car will reduce the taxable benefit.
Pool Cars: The use of a pool car does not result in a company car benefit. A pool car is one that is used by more than one employee, that is used only for business journeys (private use is only permitted if it is merely incidental to a business journey), and where the motor car is not normally kept at or near an employee’s home.
Related benefits: The motor car benefit covers all the costs associated with having a motor car such as insurance and repairs. The only cost that will result in an additional benefit is the provision of a chauffeur.
During the tax year 2017–18, Fashionable plc provided the following employees with company motor cars:
Amanda was provided with a new petrol powered company car throughout the tax year 2017–18. The motor car has a list price of £12,200 and an official CO₂ emission rate of 84 grams per kilometre.
Betty was provided with a new petrol powered company car throughout the tax year 2017–18. The motor car has a list price of £16,400 and an official CO₂ emission rate of 109 grams per kilometre.
Charles was provided with a new diesel powered company car on 6 August 2017. The motor car has a list price of £13,500 and an official CO₂ emission rate of 137 grams per kilometre.
Diana was provided with a new petrol powered company car throughout the tax year 2017–18. The motor car has a list price of £84,600 and an official CO₂ emission rate of 208 grams per kilometre. Diana paid Fashionable plc £1,200 during the tax year 2017–18 for the use of the motor car. Diana was unable to drive her motor car for two weeks during February 2018 because of an accident, so Fashionable plc provided her with a chauffeur at a total cost of £1,800.
The CO₂ emissions are between 76 grams and 94 grams per kilometre, so the relevant percentage is 17%. The motor car was available throughout 2017–18, so the benefit is £2,074 (12,200 x 17%).
The CO₂ emissions are above the base level figure of 95 grams per kilometre. The CO₂ emissions figure of 109 is rounded down to 105 so that it is divisible by five. The minimum percentage of 18% is increased in 1% steps for each five grams per kilometre above the base level, so the relevant percentage is 20% (18% + 2% ((105 – 95)/5)). The motor car was available throughout 2017–18, so the benefit is £3,280 (16,400 x 20%).
The CO₂ emissions are above the base level figure of 95 grams per kilometre. The relevant percentage is 29% (18% + 8% ((135 – 95)/5) + 3% (charge for a diesel car)). The motor car was only available for eight months of 2017–18, so the benefit is £2,610 (13,500 x 29% x 8/12).
The CO₂ emissions are above the base level figure of 95 grams per kilometre. The relevant percentage is 40% (18% + 22% ((205 – 95)/5)), but this is restricted to the maximum of 37%. The motor car was available throughout 2017–18, so the benefit is £30,102 (31,302 (84,600 x 37%) – 1,200). The contribution by Diana towards the use of the motor car reduces the benefit. The provision of a chauffeur will result in an additional benefit of £1,800.
If fuel is provided for private use, then there will additionally be a fuel benefit. This is also based on a motor car’s CO₂ emissions.
Base figure: For the tax year 2017–18 the base figure is £22,600.
Percentage: The percentage used in the calculation is exactly the same as that used for calculating the related company car benefit.
Reduction: The fuel benefit is proportionately reduced if a motor car is unavailable for part of the tax year.
The fuel benefit can also be proportionately reduced where the fuel itself is only provided for part of the tax year. However, it is not possible to opt in and out depending on monthly use. If, for example, fuel is provided from 6 April to 30 September 2017, then the fuel benefit for the tax year 2017–18 will be restricted to just six months. This is because the provision of fuel has permanently ceased. However, if fuel is provided from 6 April to 30 September 2017, and then again from 1 January to 5 April 2018, then the fuel benefit will not be reduced - the cessation was only temporary.
Contribution: No reduction is made for contributions made by an employee towards the cost of private fuel unless the entire cost is reimbursed. In this case there will be no fuel benefit.
Continuing with example 9.
Amanda was provided with fuel for private use between 6 April 2017 and 5 April 2018.
Betty was provided with fuel for private use between 6 April 2017 and 31 December 2017.
Charles was provided with fuel for private use between 6 August 2017 and 5 April 2018.
Diana was provided with fuel for private use between 6 April 2017 and 5 April 2018. She paid Fashionable plc £600 during the tax year 2017–18 towards the cost of private fuel, although the actual cost of this fuel was £1,000.
The motor car was available throughout 2017–18 so the fuel benefit is £3,842 (22,600 x 17%).
Fuel was only available for nine months of 2017–18, so the fuel benefit is £3,390 (22,600 x 20% x 9/12).
The motor car was only available for eight months of 2017–18, so the fuel benefit is £4,369 (22,600 x 29% x 8/12).
The motor car was available throughout 2017–18, so the fuel benefit is £8,362 (22,600 x 37%). There is no reduction for the contribution made because the cost of private fuel was not fully reimbursed.
The employer is responsible for paying class 1A NIC in respect of taxable benefits at the rate of 13.8%.
Continuing with examples 9 and 10.
The total amount of taxable benefits for 2017–18 is £59,829 (2,074 + 3,280 + 2,610 + 30,102 + 1,800 + 3,842 + 3,390 + 4,369 + 8,362), so Fashionable plc will have to pay class 1A NIC of £8,256 (59,829 at 13.8%).
Use of own motor car
Employees who use their own motor car for business travel must use HMRC’s authorised mileage allowances in order to calculate any taxable benefit arising from mileage allowances received from their employer. Employees who use their motor cars for business mileage without being reimbursed by their employer (or where the reimbursement is less than the authorised mileage allowances), can use the authorised mileage allowances as a basis for an expense claim.
The rate of authorised mileage allowance for the first 10,000 business miles is 45p per mile, and for business mileage in excess of 10,000 miles the rate is 25p per mile.
Unlike other taxable benefits which are subject to class 1A NIC, any taxable benefit arising from mileage allowances is treated as earnings subject to both employee and employer’s class 1 NICs.
Dan and Diane used their own motor cars for business travel during the tax year 2017–18.
Dan drove 8,000 miles in the performance of his duties, and his employer reimbursed him at the rate of 60p per mile.
Diane drove 12,000 miles in the performance of her duties, and her employer reimbursed her at the rate of 30p per mile.
The mileage allowance received by Dan was £4,800 (8,000 at 60p), and the tax free amount was £3,600 (8,000 at 45p). The taxable benefit is therefore £1,200 (4,800 – 3,600).
The taxable benefit will be included as part of Dan’s taxable income. It will also be subject to both employee and employer’s class 1 NICs.
Diane can make an expense claim of £1,400:
|10,000 miles at 45p||4,500|
|2,000 miles at 25p||500|
|Mileage allowance received (12,000 at 30p)|
Sometimes, rather than being given the amount of business mileage, you might have to ascertain what it is. Remember that business mileage does not include:
Ordinary commuting: This is where an employee drives between home and their normal workplace. This includes the situation where an employee is required to go into work at the weekend or because of an emergency such as to turn off a fire alarm.
Private travel: This is any journey that is not for work purposes.
Business mileage includes the following:
Travel to visit clients: This is provided the journey is not virtually the same as the employee’s ordinary commute, such as where an employee travels from home to a client’s premises which are situated near their normal workplace.
Travel to a temporary workplace: A temporary workplace is one where the employee expects to be based for less than 24 months. Again, there is the provision that the journey must not be virtually the same as the employee’s normal commute.
During the tax year 2017–18, Joan used her private motor car for both private and business journeys. She was reimbursed by her employer, Steam Ltd, at the rate of 40p per mile for the following mileage:
|Normal daily travel between home and Steam Ltd’s offices||2,480|
|Travel between home and a temporary workplace (the assignment was for 16 weeks)||3,360|
|Travel between Steam Ltd’s offices and the premises of Steam Ltd’s clients||1,870|
|Travel between home and the premises of Steam Ltd’s clients||830|
|Total mileage reimbursed by Steam Ltd||8,540|
- The mileage allowance received by Joan was £3,416 (8,540 at 40p).
- Ordinary commuting does not qualify for relief, but the travel to the temporary workplace does qualify as the 24-month limit is not exceeded.
- The tax free amount is £2,727 ((3,360 + 1,870 + 830) at 45p).
- The taxable benefit is therefore £689 (3,416 – 2,727).
If a sole trader or partnership uses the cash basis to calculate trading profit, then the business can use authorised mileage allowances to determine the deduction for business mileage.
Winifred is self-employed, using the cash basis to calculate her trading profit. On 10 April 2017, she purchased a motor car with CO₂ emissions of 110 grams per kilometre for £15,600. The motor car is used by Winifred, and 70% of the mileage is for private journeys. For the year ended 5 April 2018, motor expenses were £4,800, with Winifred driving 8,000 business miles.
For the year ended 5 April 2018, Winifred can claim an expense deduction of £3,600 (8,000 miles at 45p). Capital allowances and actual motor expenses are not relevant when authorised mileage allowances are claimed.
Capital gains tax and inheritance tax
The disposal of a motor car is exempt for CGT purposes, but there is no exemption from IHT. Therefore a person’s estate includes the value of any motor cars which they own at the date of death.
