Transfer pricing

There are rules potentially affecting the taxation of transactions (including loans or loan guarantees) between connected businesses. These are known as transfer pricing and thin capitalisation rules.

Small and medium-sized enterprises do not normally have to apply transfer pricing rules when they calculate the amount of tax they should pay (except for transactions with connected businesses in territories with whom we have no treaty). In this context a small and medium-sized enterprise is a group of businesses employing fewer than 250 people worldwide and with (one or both of these):
- a global turnover of less than 50 million euros (£34 million)
- a balance sheet total less than 43 million euros (£29 million)
Businesses that do not meet this definition of a small and medium sized enterprise must apply transfer pricing and thin capitalisation rules to all transactions with connected businesses which create a UK tax advantage. This includes those entirely within the UK.

70 Compensating adjustment claimed

If a business is required to make an uplift in its profits, or restriction of its losses, due to a transfer pricing adjustment for a UK-to-UK transaction with a connected business, then that other business can make a claim to assess its profits and losses on a consistent basis, by making a compensating adjustment.

Enter X if this affects your company.

75 Company qualifies for small and medium sized enterprise exemption

Enter X to confirm that your business is eligible for this exemption.

80, 85 and 90 Accounts and computations

Enter X in box 80 to indicate you’re submitting accounts for the period the return relates to.

If you’re not submitting accounts and computations, use box 90 to explain your reasons.

Computations

Include all the information you consider necessary to explain the figures in your return within the single iXBRL computations file (or using HMRC’s File your accounts and Company Tax Return online service (https://www.gov.uk/file-your-company-accounts-and-tax-return)).

For periods ending on or after 1 April 2017, your computation must identify:
- unused losses carried forward from a previous accounting period
- the total amount of unused losses arising in a period ending before 1 April 2017
- the total amount of unused losses arising in a period ending on or after 1 April 2017
If applicable, you must separately detail UK property business losses arising in a period when you were chargeable to Income Tax on your:
- UK property business profits
- other UK property income
Your calculations should show:
- how these losses were utilised in this accounting period
- the amounts of pre or post 1 April 2017 loss and Income Tax property losses (where applicable) that you’re carrying forward to the next accounting period
- the amount of deductions allowance used (read Section 269ZZ(1)(a) of the Corporation Tax Act 2010 (https://www.legislation.gov.uk/ukpga/2010/4/section/269ZZ))

Supplementary pages provide a standard format to help you submit the information HMRC needs. It’s important to get this right because your completed supplementary pages form part of your company’s return and are covered by the declaration.

Warnings about prosecution, late and incorrect returns and late payment of tax also apply to the supplementary pages.

Your computations should include a detailed calculation of this figure. For periods ending on or after 1 April 2017, new loss reform rules apply and your calculations must also show the amount of ‘trading profits deductions allowance’ you’ve used. For more information read:
- Section 269ZB(7)(a) of the Corporation Tax Act 2010 (https://www.legislation.gov.uk/ukpga/2010/4/section/269ZB)

To assist with completing this section and box 526, read this example.

Example

This example should help you complete boxes 471 to 474 and box 526 (Coronavirus support schemes overpayment now due).

Company A’s accounting period was 1 January 2020 to 31 December 2020. It claimed £135,000 in Coronavirus Job Retention Scheme grants. The claim for December 2020 was not received until 6 January 2021, so the Coronavirus Job Retention Scheme grants received during that accounting period were only £120,000.

This meant the company over-claimed £5,000 in May 2020. Because they reduced their July claim by £5000 this did not result in an overpayment.

In February 2021, the company identified that a further over-claim of £10,000 was received in 2020. They made a voluntary disclosure and repaid £5,000 of this amount.

In September 2021, they identified an additional over-claim of £8,000 was received in 2020. They did not disclose this amount.

The company did not make any Eat Out to Help Out claims or payments.

Based on this information, Company A completed their return as follows:

Box 471 Coronavirus Job Retention Scheme received: £120,000

This is the amount of Coronavirus Job Retention Scheme grant that they received.

Box 472 Coronavirus Job Retention Scheme entitlement: £102,000

This is calculated as:
- The amount received: £120,000
- Minus the over-claim identified in February 2021: £10,000
- Minus the over-claim identified in September 2021: £8,000
Box 473 Coronavirus Job Retention Scheme overpayment already assessed or voluntary disclosed: £10,000

This is the amount voluntarily disclosed in February 2021 and is included whether paid or not.

Box 474 Other coronavirus overpayments: £0

Box 526 Coronavirus support schemes overpayment now due: £8,000

This is calculated as:
- The sum of boxes 471 (£120,000) and 474 (£0) = £120,000
- £120,000 minus the sum of boxes 472 (£102,000) and 473 (£10,000) = £8,000
This is the amount that was over-claimed but not subject to a voluntary disclosure. This means it’s an overpayment and must be repaid. The £5,000 unpaid voluntary disclosure will be assessed separately.

Overpayments and repayments

Enter the company (or nominee) bank or building society details (boxes 920 to 940) on every return you complete, whether or not you think there may be a repayment.

Repayment may be made direct to your card if you paid the tax by debit or credit card. Make sure you enter X in box 40 or 45 to alert HMRC that a repayment may be due.

860 Small Repayments

Complete this box if you do not want HMRC to make repayments less than a certain amount. HMRC sets any overpayments you have against any other Corporation Tax liability before repaying them. Where a repayment is due, we will:

You can prevent HMRC from making an automatic repayment by entering an amount over £100 in box 860. If your overpayment is over £100 and you enter an amount greater than £100, we will not make any repayment unless it’s more than the limit you’ve chosen. Repayments include tax, payable credits, interest, and late filing penalties or any combination of them.
