CT600 Box 540: Creative Tax Credits

CT600 Box 540 is where creative industry companies record their Creative Industry Tax Credits when filing their company tax return with HMRC. These specialist reliefs support UK companies producing films, television programmes, video games, theatrical productions, orchestral concerts, and museum or gallery exhibitions.

If your company is not active in one of these qualifying creative sectors, Box 540 will not apply and should be left blank.

What Is CT600 Box 540?

Box 540 appears in the Tax Payments and Overpayments section of the CT600 form. It captures the total creative industry tax credit being claimed — a figure that flows from the dedicated supplementary pages your company must submit alongside the main corporation tax return.

From returns submitted on or after 6 April 2026, companies claiming creative industry reliefs must include the CT600P Creative Industries supplementary page. This page records the detailed computation of your relief entitlement. Box 540 on the main CT600 then reflects the total credit figure derived from that supplementary page.

Because Box 540 depends on the supplementary pages, you cannot correctly complete it without first working through your sector-specific supplementary computation. The CT600 alone is not sufficient to support a creative industry tax credit claim.

Which Creative Sectors Qualify?

HMRC recognises eight types of creative industry relief. Your company must be directly involved in the production and development of content in one of the following sectors:

  • Film — feature films and documentary films holding British certification
  • High-end television — dramas and other programmes meeting the minimum core expenditure test
  • Children's television — animated and live-action children's programming
  • Animated television — animated series and programmes
  • Video games — development of commercially released video games
  • Theatrical productions — plays, musicals, opera, and ballet
  • Orchestral concerts — live orchestral performances
  • Museum and gallery exhibitions — touring and fixed exhibitions
For films, high-end television, and video games, your programme or game must hold British certification, obtained through a cultural test or a qualifying co-production treaty. The British Film Institute (BFI) administers the certification process for these sectors.

Orchestral concerts, theatrical productions, and museum exhibitions have their own eligibility tests and do not require BFI certification, but they must pass the relevant British or European cultural test.

What Are Creative Industry Tax Credits?

There are two types of creative industry relief:

1. Corporation Tax reliefs — these increase your company's allowable deductions, reducing the profit on which you pay Corporation Tax. The relief reduces your CT liability but does not generate a cash payment if you are profitable.

2. Expenditure credits — these are taxable credits calculated as a percentage of your qualifying expenditure. The credit offsets your Corporation Tax liability, and any surplus — where the credit exceeds your tax bill — may be payable to your company as a cash amount.

The relief rates vary by sector. Rates are set by HMRC and can change following Budget announcements. Always check the current GOV.UK guidance for your specific sector, or work with a specialist adviser who can confirm the rates that apply to your accounting period.

Who Can Claim?

Eligibility is tightly defined. To claim creative industry tax credits through Box 540, your company must:

  • Be liable to UK Corporation Tax — exempt charities and partnerships cannot claim directly (though company members of a partnership may be able to claim their share)
  • Be the production company — the entity actively responsible for making the creative work, not a commissioner, broadcaster, or passive investor
  • Have been actively involved in decision-making throughout the project, from pre-production to completion
  • Be directly negotiating and paying for the rights, goods, and services required
  • Have incurred qualifying expenditure — costs that would not have been incurred had the creative project not taken place
This definition of the production company is important. Many businesses in the creative sector — studios, distributors, broadcasters, post-production houses — do not qualify because they are not the entity in control of the production. Only one company can be the production company for any given project.

How to Claim Creative Tax Credits

Claiming creative industry tax credits through Box 540 involves several steps:

  1. Confirm your sector qualifies — check GOV.UK guidance or speak to a specialist adviser for your sector
  2. Obtain certification where required — for films, high-end TV, and video games, apply to the BFI for British certification before your accounting period ends if possible
  3. Identify qualifying expenditure — compile all costs that meet the expenditure conditions for your sector
  4. Complete the CT600P supplementary page (from 6 April 2026) — or the relevant predecessor supplementary pages — to calculate your credit
  5. Enter the credit in Box 540 — transfer the figure from your supplementary computation to the main CT600
  6. Submit your return — file the main CT600 along with the supplementary pages and any required computations
Claims can be made in your original return or in an amended return. The standard Corporation Tax time limit for amended returns applies — generally within two years of the end of your accounting period, though this can extend to four years in some circumstances.

Recent Changes — CT600P from April 2026

HMRC updated the creative industry claims process following reforms to the supplementary pages system. From returns submitted on or after 6 April 2026, all creative industry claims must include the new CT600P supplementary page, regardless of which sector you are in.

This replaces a range of sector-specific supplementary pages that previously applied separately to film, video games, high-end television, and so on. The CT600P consolidates all creative industry relief computations into a single document.

If your accounting period ends before April 2026 but you submit after that date, check whether CT600P is required for your return. HMRC guidance makes clear that the requirement is based on the submission date, not the period end date.

Common Mistakes to Avoid

Claiming without BFI certification — Films, high-end television, and video games require British certification. You cannot claim without it, even if your content is clearly culturally British. Apply to the BFI early — certification can take time.

Wrong company claiming — Only the production company can use Box 540. If you are a service company providing crew, facilities, or post-production to the production company, you cannot claim creative tax credits on their behalf.

Missing CT600P from April 2026 — Returns submitted on or after 6 April 2026 must include the CT600P supplementary page. Omitting it may leave your claim incomplete or cause HMRC to reject it.

Including subsidised expenditure — Expenditure that has been covered by grants, public funding, or other state subsidies may not qualify. Subsidised amounts must be excluded from qualifying expenditure calculations.

Incorrect expenditure categorisation — The definition of qualifying expenditure differs by sector. High-end television has a minimum core expenditure test (expenditure must meet a percentage threshold), while theatrical productions apply different rules. Do not assume the same rules apply across all eight sectors.

Worked Example

A small UK animation studio produces a children's animated series over an 18-month production period. The series qualifies as a British programme under the cultural test, and the studio holds BFI certification confirming this.

The studio's qualifying production expenditure for the accounting period is £400,000. It completes the CT600P supplementary page, calculating its entitlement at the applicable credit rate for animation. The resulting credit figure is entered in Box 540 of the CT600.

Because the studio made a loss during the production period, its Corporation Tax liability is nil. The credit in Box 540 exceeds the tax liability, so HMRC pays the surplus as a cash repayment to the studio — helping to fund the continuation of the project.

If your company conducts research and development work as part of the creative process — for example, developing proprietary software tools or novel production techniques — you may also be interested in the R&D tax credit system. See our guide to CT600 Box 530: R&D Tax Credit.

Summary

CT600 Box 540 is used by production companies in qualifying creative sectors to claim creative industry tax credits on their company tax return. Eligibility is restricted to the company actively responsible for making the creative work. Claims require completion of the CT600P supplementary page for returns filed from 6 April 2026 onwards. Relief rates vary by sector and can change following government announcements, so always verify current figures on GOV.UK or with a specialist creative tax adviser.
