If your company profits sit between £50,000 and £250,000, marginal relief can soften the jump from 19% to 25% Corporation Tax.

The Corporation Tax main rate applies to companies with taxable profits above £250,000 and is currently set at 25%. Companies with profits of up to £50,000 are subject to the Small Profits Rate, which remains at 19%.

For companies with profits falling between £50,000 and £250,000, marginal relief applies. This creates a gradual increase in the effective rate of Corporation Tax between the small profits and main rates, rather than a sudden jump. The lower and upper profit limits are proportionately reduced where an accounting period is shorter than 12 months or where a company has associated companies.

The effect of marginal relief is that the effective Corporation Tax rate increases steadily from 19% once profits exceed £50,000, reaching the full 25% rate when profits exceed £250,000.

In practice, Corporation Tax is calculated by applying the main rate of 25% to total taxable profits and then deducting the marginal relief due. The marginal relief standard fraction is 3/200. HMRC provides an online marginal relief calculator to help companies determine the correct amount of Corporation Tax payable based on their profit level and circumstances.

If your business works in film, TV, games or the arts, Creative Industry Tax Reliefs could reduce your Corporation Tax bill and may even generate a payable tax credit.

Creative Industry Tax Reliefs (CITR) are a range of UK Corporation Tax reliefs designed to support companies operating in the creative sector. The reliefs allow qualifying companies to increase the amount of allowable expenditure when calculating their taxable profits, thereby reducing the Corporation Tax they are required to pay. Where a company is loss-making, it may be possible to surrender those losses in exchange for a payable tax credit.

CITR covers a wide variety of creative activities. Reliefs are available for film, animation, high-end television, children’s television and video game production, as well as for theatre, orchestra performances, and museums and galleries exhibitions. More recently, the Audio-Visual Expenditure Credit and the Video Games Expenditure Credit have been introduced, offering an alternative credit-based system for eligible productions.

To qualify for CITR, films, television programmes and video games must meet specific cultural criteria. This is usually achieved by passing a formal ‘cultural test’, which assesses various factors such as content, setting and the nationality of key personnel. Alternatively, a production may qualify through an internationally agreed co-production treaty. Meeting these requirements allows the production to be certified as a British film, British programme or British video game.

Certification is administered by the British Film Institute (BFI) on behalf of the Department for Culture, Media and Sport. The BFI can issue an interim certificate while production is ongoing, followed by a final certificate once the project has been completed. This certification is a key requirement for claiming the relevant tax reliefs.

Companies can reduce their Corporation Tax bill through a range of reliefs, including R&D credits, Patent Box, and creative industry tax reliefs, all of which will help to lower the overall tax on profits. Your company can also claim capital allowances for assets such as equipment, machinery and cars bought to use in your business.

The basic Corporation Tax reliefs include the following:

Research and Development tax reliefs – The R&D expenditure credit (RDEC) and enhanced R&D intensive support (ERIS) came into effect for accounting periods beginning on or after 1 April 2024. While the expenditure rules for both are the same, the calculation methods differ. The merged RDEC scheme is a taxable expenditure credit available to eligible trading companies subject to UK Corporation Tax. Even if a company qualifies for the ERIS, it may choose to claim under the merged scheme instead, but both schemes cannot be claimed for the same expenditure.

The Patent Box – This relief allows qualifying companies to apply a lower 10% corporation tax rate on profits arising from patent exploitation.

Creative industry tax reliefs (CITR) – This is the term for a collection of Corporation Tax reliefs that allow qualifying companies to claim a larger deduction, or in some circumstances claim a payable tax credit when calculating their taxable profits. The relief applies to qualifying expenditure in the production of certain films, high-end television, animation, video games, children’s television, theatre, orchestra and museum & galleries exhibitions.

Relief on goodwill and relevant assets – If the relief is available, it is at a fixed rate of 6.5% a year. This is on the lower of the cost of the relevant asset or 6 times the cost of any qualifying IP assets in the business purchased.

Loss relief – There are various Corporation Tax reliefs that may be available where your company or organisation makes a trading terminal, capital or property income losses. For example, trading losses may be used to claim relief from Corporation Tax by offsetting the loss against other gains or profits of the business in the same or previous accounting period.

Non-UK resident companies that buy, develop, or sell UK land must register for Corporation Tax within three months of a disposal.

Those non-UK resident companies that deal in or develop UK land must register for Corporation Tax if their activities involve acquiring or developing property with the intention to profit from its disposal. This requirement applies when the land is held as trading stock, or when a main purpose of acquiring or developing land is to sell it for profit. This is different from acquiring property for investment purposes, such as rental income.

Companies are required to register within three months of making a disposal of UK land. The registration process involves providing essential details, including the company name, country of incorporation, registration number, addresses (both the registered office and the UK business address) and the date the company became liable to Corporation Tax. If the company is part of a group, details of the parent company must also be provided.

Registration can be completed online, after which companies must print and submit the form to HMRC. Alternatively, if online registration is not possible, companies can send a letter with the required information, including a 10-digit dummy Unique Taxpayer Reference (UTR). Once HMRC processes the registration, the company will receive its Corporation Tax UTR.

Paying Corporation Tax? Always use the correct reference or risk delays and penalties.

To pay Corporation Tax via online or telephone bank transfer, you can use either a UK or overseas bank account.

UK Bank Accounts

You can transfer funds using Faster Payments, CHAPS, or Bacs, either online or by calling your bank. Faster Payments usually reach HMRC on the same or next day (including weekends), CHAPS payments arrive the same working day if made within your bank’s cut-off time, and Bacs payments typically take up to 3 working days.

Use the account details provided in your HMRC ‘notice to deliver your tax return’ or reminder. If unsure, use one of the following:

• HMRC Cumbernauld
  • Sort code: 08 32 10
  • Account number: 12001039
• HMRC Shipley
  • Sort code: 08 32 10
  • Account number: 12001020

Overseas Bank Accounts

You can also pay from an overseas account using:

• HMRC Cumbernauld
  • IBAN: GB62 BARC 2011 4770 2976 90
  • BIC: BARCGB22
• HMRC Shipley
  • IBAN: GB03 BARC 2011 4783 9776 92
  • BIC: BARCGB22

You must ensure to include your 17-character Corporation Tax payment reference number for the correct accounting period. This reference changes each year so it is important to use the up-to-date reference number. Using the wrong one can delay your payment. You can find it in your company’s HMRC online account or on your ‘notice to deliver your tax return’ or on any reminders from HMRC.
