About this return

40 Repayments this period

Enter X if you think a repayment is due for this period. You can speed up your repayment by entering your bank or building society details in boxes 920 to 940.

HMRC’s detailed guidance on tax avoidance provides more information about the disclosure regime.

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 (SMEs) 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 (SME) is a group of businesses:

• employing fewer than 250 people worldwide
• with a global turnover of less than 50 million euros (£34 million)
• and/or a balance sheet total less than 43 million euros (£29 million)

Businesses that do not meet this definition of an SME 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 SME exemption

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

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).

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:

Enter the total amount of Coronavirus Job Retention Scheme payments received in the accounting period for which you were entitled to claim. Include amounts you received that you were entitled to but repaid voluntarily at the time of filing your return.

Do not include any amounts that you were entitled to when you made the claim, but were not entitled to retain by the end of the accounting period. For example, where an amount received was not used for the required purpose.

The figure in box 472 cannot exceed the figure in box 471. If you do not complete box 472, the figure in box 471 (less the amount repaid or assessed in box 473) will be assessed to income tax as a Coronavirus Job Retention Scheme overpayment.

Do not:

• include any overpayments chargeable in the accounting period that have not yet been disclosed to, or assessed by, HMRC, at the time of completing this return

This box should also be used to report Coronavirus Job Retention Scheme overpayments for amounts received in an earlier accounting period that you are not entitled to retain in this accounting period.

To assist with completing this section and box 526, an illustrative example is shown below:

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 (CJRS) received: £120,000

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

Box 472 CJRS entitlement: £102,000

This is calculated as:

1. The amount received: £120,000
2. Minus the over-claim identified in February 2021: £10,000
3. Minus the over-claim identified in September 2021: £8,000

Box 473 CJRS 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:

1. The sum of boxes 471 (£120,000) and 474 (£0) = £120,000
2. £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.

Calculation of tax outstanding or overpaid

475 Net Corporation Tax liability

Enter the figure from box 440 minus the figure from box 470.

Northern Ireland information

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.

HMRC can make repayments direct to a bank or building society account but, for security reasons, only the details entered in boxes 920 to 940 from your latest return will be used. 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 below 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:

• automatically repay an overpayment of more than £100
• automatically repay an overpayment of £100 or less when you enter bank details in boxes 920 to 940 (this happens even if you’ve entered an amount of less than £100 in box 860)
• set any repayment of £100 or less against later accounting periods if you do not enter any bank details in boxes 920 to 940

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 above the limit you’ve chosen. Repayments include tax, payable credits, interest, and late filing penalties or any combination of them.

Complete boxes 900 to 915 instead of box 860 if you want to surrender a tax refund under section 963 of the Corporation Tax Act 2010 to another group company.

Any repayment limit authority provided for previous return periods will not be carried forward. You must renew or change the limit each time you complete a Company Tax Return, even if you’re submitting two returns at the same time.
