Patent Box and creative reliefs: which HMRC tax credits suit small firms

What to take away

• Business tax credits from HMRC are not grants: Patent Box, Video Games Tax Relief and Theatre Tax Relief reduce the Corporation Tax a company pays on particular profits.
• Patent Box needs a qualifying patent and a company that has developed or exploited the invention, plus the qualifying IP requirement tracked through the claim.
• Video Games Tax Relief and Theatre Tax Relief sit inside the creative industry reliefs and are claimed through the Corporation Tax return, not a separate application.
• Each relief has its own record-keeping duty, and HMRC expects the calculations, contracts and evidence to be kept for at least six years.
• Reliefs stack awkwardly with R&D claims and with each other, so the order of claims matters to the final tax figure.

Which HMRC tax credits suit small companies, and how they differ

Small firms often use "tax credits" loosely. In practice HMRC runs a set of Corporation Tax reliefs that reduce taxable profit or the tax itself, and each has its own gate. The Patent Box rewards profit from patented inventions.

The creative industry reliefs reward companies that make video games, theatre, film, television, animation or high-end television. The creative industry tax reliefs available to companies are a family, not one scheme, and each member has its own cultural test or eligibility route.

The first question is what the company actually owns or produces. A software firm with a patented process looks at Patent Box. A studio making an eligible game looks at Video Games Tax Relief. A theatre producer with a qualifying touring or production company looks at Theatre Tax Relief.

A firm with none of those may still have an R&D claim, but that is a different route.

The second question is how the relief arrives. Patent Box and the creative reliefs are claimed in the Company Tax Return, usually through the computations and supplementary pages. There is no grant application, no competition and no panel. That makes them quieter than grant funding, but it also means the evidence sits with the company until HMRC asks.

The third question is timing. A Patent Box claim follows a patent being granted, so the earliest years of a product may not qualify. Creative reliefs often depend on the production being completed and, in some cases, on a British certification. Small firms that plan cash flow around a claim should build in the lag.

Reliefs also differ in generosity and complexity. Patent Box uses a formula that links profit to qualifying IP and to the company's own development work. Creative reliefs can be claimed as an additional deduction or, for some, as a payable tax credit where the company makes a loss. The choice affects how much cash comes back and when.

If you are comparing these against grant funding, the grant trends to monitor show how public money is shifting, but tax reliefs remain the steadier route for firms with real intellectual property.

Patent Box: eligibility tests and the qualifying IP requirement

Use the Patent Box to reduce your Corporation Tax on profits from patented inventions, but only if the company meets two tests. The first is the qualifying IP requirement: the company must hold a qualifying patent, or an exclusive licence over one, and the patent must be granted by a recognised patent office.

A pending application does not count until grant.

The second is the development test. The company must have carried out qualifying development work on the invention, or had it carried out on its behalf, or performed a significant amount of activity to develop the invention or a product incorporating it. A company that simply bought a patent and licenses it out may struggle here.

The relief does not apply to all profit. It applies to a share of the profit attributable to qualifying IP, calculated through a formula that starts with the profit on the relevant products and then applies a routine return deduction. The remaining qualifying profit is taxed at a reduced effective rate rather than the main rate.

That formula is why records matter. HMRC expects the company to identify the products that incorporate the patented invention, trace the income and costs attached to them, and show how the routine return was calculated. A spreadsheet built after the year end is weaker than contemporaneous records.

The qualifying IP requirement also looks at how the invention was developed. Where a company acquired the patent or had development done by a connected party, the rules can reduce the benefit. Small firms that license in technology should check the ownership and development history before assuming a claim is available.

Companies can elect into the Patent Box, and once in, the relief applies to relevant profits for the accounting period. The election is not a one-off application to a panel; it is a position taken in the return. That means it can be revisited, but it also means the supporting analysis should be able to survive enquiry.

Creative industry reliefs: Video Games Tax Relief and Theatre Tax Relief

Video Games Tax Relief supports companies that develop video games intended for supply. The game must pass a cultural test administered by the British Film Institute, and the company must be responsible for the development, planning and decision-making.

Qualifying expenditure on the game's core development can attract an additional deduction, and loss-making companies may be able to surrender the loss for a payable tax credit.

Theatre Tax Relief works in a similar shape for theatre production companies. The production must qualify, often through a cultural test, and the company must be responsible for the production. Qualifying expenditure can generate an additional deduction, and a loss-making company may claim a payable credit.

Touring productions have historically been treated more generously than non-touring ones, so the classification matters.

Both sit within the creative industry reliefs, alongside film, television, animation and high-end television reliefs. The common thread is that the company must be the producer, not merely a contractor, and the production must meet the relevant cultural conditions. Companies that act as service providers for someone else's production usually fall outside.

Small firms often trip on the definition of qualifying expenditure. Costs that relate to the production can qualify, but costs of marketing, financing or general overhead usually do not. The split needs to be worked out production by production, with contracts and timesheets to back it up.

The payable credit is the part that attracts attention, because it can turn a loss into cash. It is not automatic. HMRC expects the company to show that the loss arose from the qualifying activity and that the claim is properly calculated. A claim built on a rough estimate of production spend is the kind that gets opened.

If a company is also considering grant funding for a production, the subsidy control to advertising rules can affect what public support is compatible with a relief claim, so check before stacking both.

The claims process and records HMRC expects for each relief

All of these reliefs are claimed through the Company Tax Return. The company computes its profit, applies the relief in the computations, and files the return with the supporting supplementary pages where required. There is no separate HMRC application form for Patent Box or for the creative reliefs in the way there is for a grant.

1. Check eligibility before the year end, including any cultural test or patent grant.
2. Identify the qualifying income, expenditure and profits and keep the working papers.
3. Prepare the computations showing the relief and the effect on the tax liability.
4. Complete the relevant supplementary pages and file the Company Tax Return by the filing deadline.
5. Keep the evidence, and amend the return if the position changes.

Records should include the patent or licence documents, the development or production contracts, the cost records, and the calculations that link the relief to the figures in the accounts. HMRC can enquire into a return, and the burden of showing the claim is correct sits with the company.

HMRC guidance on claims in the Corporation Tax collection is the place to check the current forms and notes.

A simple checklist for the file:

• Patent grant certificate or exclusive licence agreement
• Development or production contracts and schedules
• Cost records split between qualifying and non-qualifying
• Cultural test certificate or BFI correspondence where relevant
• The relief calculation and the link to the accounts
• Evidence of the company's role as developer or producer
• Correspondence with HMRC and any amendment history

Companies should keep these records for at least six years after the end of the accounting period. Where a claim is amended or an enquiry opens, the period can run longer. Storing the working papers with the accounts, rather than in a folder that gets overwritten, saves time later.

How these reliefs interact with Corporation Tax and R&D claims

Corporation Tax is the tax these reliefs reduce, and the interaction matters. Patent Box reduces the effective rate on qualifying profit. Creative reliefs reduce profit through an additional deduction or produce a payable credit. Both change the profit figure that the main rate applies to.

R&D tax relief is separate but often claimed by the same company. A firm developing a patented product may have both an R&D claim and a Patent Box claim, and the two use different definitions of qualifying activity. Claiming both is possible, but the calculations must not double count the same expenditure or profit.

The order of claims affects the outcome. R&D relief usually reduces the profit before Patent Box is calculated, which can reduce the Patent Box benefit. Advisers often model the combination rather than assume both apply at full value. Corporation Tax rates, expenses and reliefs set the rates that the final calculation uses.

Small firms should also watch the interaction with losses. A payable credit under a creative relief uses a loss that might otherwise be carried forward. Surrendering the loss for cash is a choice with a cost, and it should be made with the company's future profit in mind.

Where a company has both creative output and patented technology, the claims can sit side by side in one return. The risk is not that they conflict in principle, but that the working papers blur the boundaries. Keep each relief's calculation separate and labelled.

Common eligibility traps for small firms and how to avoid them

A frequent trap is assuming a patent application is enough. Patent Box needs a granted patent, so a claim made in the application year is premature. Wait for grant, then check whether the earlier period can be covered by an amended return.

Another trap is treating a contractor as a producer. Video Games Tax Relief and Theatre Tax Relief expect the company to be responsible for the production. A studio that only supplies staff to another company's project is unlikely to qualify, however much of the work it does.

The cultural test catches firms that assume their production is obviously British. The test looks at content, production activity and personnel, and a production can fail on points even when it feels British. Applying early, and keeping the correspondence, avoids a scramble at filing.

Record-keeping is the quiet trap. Claims are made in a return and checked later, so a company that cannot show how it split qualifying and non-qualifying costs is exposed. Build the split as the costs are incurred, not after the year end.

Finally, firms sometimes stack reliefs without checking the combined effect. R&D, Patent Box and a creative relief can all touch the same profit, and the total benefit is rarely the sum of the headline rates. Model the combination, and read the rules and ethics from application if public funding is also involved.

If you use an adviser, the research tools, application systems that firms use for grants can also help organise relief claims, but the responsibility for the return stays with the company.

Common questions

Can a small company claim Patent Box and R&D relief on the same project? Yes, in principle. The two use different definitions, so the calculations must be kept separate to avoid counting the same expenditure or profit twice.

Does Video Games Tax Relief need a cultural test? Yes. The game must pass a cultural test administered by the British Film Institute, and the company must be responsible for the development.

Is Theatre Tax Relief different for touring productions? Touring and non-touring productions have been treated differently, so the classification affects the rate of relief. Check the current rules for the accounting period.

How long should records be kept? At least six years after the end of the accounting period, and longer if HMRC opens an enquiry or the return is amended.

Can a loss-making company get cash back from these reliefs? Some creative reliefs allow a loss to be surrendered for a payable tax credit. Patent Box reduces tax on profit, so it does not produce a payment where there is no profit.

Do these reliefs count as public funding for grant purposes? They are tax reliefs rather than grants, but where a project also receives public funding, the interaction should be checked against subsidy control rules.
