“I’m working for Hovione for more than 35 years with various roles in finance, supply chain and general management in Portugal, Macau and Ireland

Early 2009 I was transferred from Hovione in Portugal to Cork, Ireland with a mission of setting up, at the new Hovione acquisition in April 2009 – the Pfizer API Loughbeg Site in Ringaskiddy – the Finance, IT, Supply Chain / Logistics structure and operations departments

One of the very first persons I met in Cork after my arrival in 2009 was John Collins, partner of T.A.S, to learn about the finance, accounting and taxation modus operandi in Ireland.

I contracted T.A.S. as a service provider to perform the accounting package and related legal and tax obligations for the first year of activity of Hovione in Cork.

For the past five years TAS is providing services to Hovione and, iMAX a subsidiary of Hovione, mainly in areas such as:

  • Payroll
  • VAT planning advice
  • R&D Tax Credits assessment
  • Compliance Reviews on Capital Allowances and Tax Managements and Annual Returns preparation and submission
  • Auditing IDA Grants for Capital and Training expenditures
  • Acting as company Secretary and related services

The business relationship and continuous business was built along the years based on the level of professionalism demonstrated by TAS Partners and Team but also on the friendly and flexible approach to support us on clarifications and explanations of questions that we frequently had along the past years, not only on the day to day basis but also as new comers established in Cork, Ireland.”
