Maximise Tax Efficiency Using the UK Patent Box Regime

Many companies have already claimed R&D tax relief to some extent, and some may have faced an enquiry from specialist tax inspectors as a result of their claim. However, there is often more that can be claimed. The Tax Advisory Partnership Innovation Tax Reliefs team offers a professional second opinion and comprehensive R&D tax review to help you maximise your eligible tax credits.

We have reviewed numerous R&D tax claims and submitted replacement claims to HM Revenue and Customs (HMRC) where we identified that previous claims were understated. Our specialists have deep expertise in R&D tax relief and understand the HMRC guidance thoroughly. We know where and how claims can be improved while fully complying with the rules.

Our second opinion tax claim service includes expert support during HMRC enquiries, including meetings with HMRC inspectors to defend and support your claim. To date, all our claims have been accepted by HMRC regarding technological or scientific qualification.

We offer flexible fee structures based on success, so we only charge if you receive a tax repayment following our work. Additionally, if we cannot improve your claim, we will let you know — providing a valuable assurance exercise for your business, even if you decide not to proceed with a new claim.

Innovation Tax Reliefs

How We Can Help with Your R&D Tax Claims and HMRC Enquiries

Projects: We know exactly which projects qualify for R&D tax relief and which don’t. Our team has identified projects previously overlooked and successfully demonstrated their eligibility to HMRC inspectors.

Costs: We understand which costs are eligible for R&D tax relief. We have reclaimed costs that were previously excluded or increased claims where only partial costs were considered.

SME Claims: Many SMEs must claim under the lower Research and Development Expenditure Credit (RDEC) scheme. These rules are often misunderstood or misapplied by some accountants. We know the differences and ensure you claim correctly and at the right time.

Specialists: Our R&D tax relief team includes engineers and experts from multiple scientific and technological sectors—not just accountants—ensuring a thorough and accurate approach that maximizes your claim.
