R&D Tax Credit Specialists

Did you know you only have two years to claim R&D tax credits if you spend money on R&D? While R&D tax credit is a great benefit to your business and could bring £27 for every £100 spent in R&D as cashback in your business the rules are highly complex and changing regularly. HMRC could impose a penalty for incorrect claims. We have several years of experience in claiming R&D tax credits and could make the process of the claim smooth for you and your business.

Watermill  has proved to be an invaluable partner for us over the past 12 months. Patience in explaining accounting processes we transitioned between ERP software and guidance to maximise opportunities offered through R&D tax credits have made the management of these areas considerably less stressful and more fruitful than they would have otherwise been. There was a lot of cleaning up required concerning our historical accounting; Watermill took this in their stride

Watermill Consulting initiated the idea to recover the R&D tax credit, which our previous accountants had failed to make us aware of. To date, we have recovered nearly £50,000, which has been invaluable in terms of cash flow, continuing to develop our R&D, employ additional consultants, and strengthen our core business. We have found Watermill to be courteous, very professional, and timely in the provision of advice, submitting, and winning refunds on our behalf.

Watermill has been instrumental in helping set up our UK office and in drafting the financials for the acquisition of Intellectual Property in the UK. We have now outsourced all our bookkeeping, payrolls, and R&D tax credit claims work to Watermill, who has also handled all our accounts and all compliance-related work regarding HMRC. Watermill is a conscientious accounting firm that has been quick and efficient throughout our association. They have a good team and are very accommodating.
