UNITED KINGDOM · EXPLORE YOUR R&D POTENTIAL

Could the work you are already doing be worth more?

Developing a product, improving a process or solving a difficult technical problem? You do not need to call it “R&D”. Start with the work and a few ballpark figures—we will handle the tax workings.

  • Around 2–3 minutes
  • No tax knowledge needed
  • A briefing to share with your team
Start with the work.

This is a first look at the opportunity, not a tax return. Rough figures are fine, and “not sure” is a useful answer.

This relief is for companies within Corporation Tax, the company tax system, even if they currently make a loss. A sole trader or ordinary partnership does not claim this company relief.

Choose a year to get started. If your accounts run April to March, for example, choose your exact dates. Rates and deadlines depend on the period.

Think about testing an unfamiliar material, overcoming a manufacturing limitation or developing a genuinely new technical capability. Being new to your business, a difficult deadline or an unusual customer request is not enough on its own. A consultation can help you check the technical detail.

What went into the work?

Enter approximate amounts for the development work, not your whole business. For example, someone costing £50,000 who spent one day in five on it represents about £10,000 here. Leave anything that does not apply blank. Count each cost once and leave out VAT you can recover.

People on your payroll

Salaries, employer National Insurance and employer pension contributions for time spent on this work. Do not include dividends.

Materials, prototypes & testing supplies

Materials used up in trials, prototypes that were not sold, and the work’s share of electricity, fuel and water. Do not include equipment purchases or materials in products sold to customers.

Software & computing

Software licences and computing used on the development work. For example, design software, simulation tools or development servers—not general office use.

Outside specialists & subcontractors

Independent UK specialists paid to carry out development work for you. Do not include routine subcontracted delivery. Enter the amount before tax-rule restrictions; we apply those for you.

A couple of other costs that may apply
Agency workers

Workers supplied by an independent agency who worked under your team’s direction on UK development activity. This is different from paying a contractor to deliver its own project.

Clinical-trial volunteers

Payments to people taking part in a clinical trial. This is usually relevant to medical or pharmaceutical development, not ordinary product-user testing.

One last thing about the business.

Profit is what is left after business costs—not turnover or the money in the bank. A loss does not automatically rule out support. You do not need to know your tax rate or choose a tax scheme.

If you leave the figure blank, we will show a clearly labelled example rather than pretend to know your tax position. If you made a loss, our team can also check whether enhanced support is available.

Anything about the work that may need a specialist review?

For example, development carried out overseas, suppliers owned by the same people as your business, costs already claimed elsewhere, or another company paying you to develop something. These can change the answer.
