A specialist could start by checking that your company is chargeable to UK Corporation Tax, then look at whether the project sought an advance in the overall field of science or technology, not just for your business, by seeking to resolve scientific or technological uncertainty. HMRC guidance says you need to be able to explain the work done, including successes and failures. They could then identify the qualifying costs, the accounting period and the deadlines, including whether a claim notification form is needed. Be cautious of anyone who gives a figure before reviewing your work, as the outcome depends on your company’s facts.
