Who we've worked with

Enterprise Therapeutics

"Enterprise Therapeutics has been working with Colin and his team at Confluence Tax on day-to-day tax matters, including the R&D tax credit claims, for a number of years.  What was nice was to work with Confluence Tax recently on a more complex project – the demerger and sale of part of our business to Roche. The team were unfailingly responsive throughout and worked seamlessly with the company and the lawyers to ensure tax ended up not being an issue during extensive 3rd-party due diligence. We continue to work closely with Confluence Tax and look forward to doing so for a long time to come."

Phil Boyd, CFO, Enterprise Therapeutics

“At Quethera we were delighted to have the assistance of the team from Confluence Tax to advise us on tax and structuring matters in preparation for, and during, our sale to Astellas. Confluence’s support was invaluable and I look forward to working with Colin and his team into the future.”
Piers Morgan, Director

Atopix Therapeutics

Colin and his team provided excellent tax advice on our company exit to Chiesi. They took a proactive and robust approach which helped progress the deal. I look forward to working with them on future projects
Tim Edwards, Atopix Therapeutics 


I have been using the services of Confluence Tax since it was formed. Colin and his team provide a ‘one-stop shop’ for just about all our tax advisory and compliance requirements – corporate taxes, R&D tax credits, share incentives, personal tax, transfer pricing and more. Working with a small and knowledgeable team is a real pleasure, as well as being efficient and cost-effective. The alternative is to use a large firm with a different ‘expert’ for each subject area, but who does not know you or your business
Michael Black, Nexeon
