Experience that matters

Simon Mason, our Director and Principal, qualified in 2003 as a Chartered Accountant with the Institute of Chartered Accountants in England and Wales.

Simon Mason

He initially trained and worked in a large regional firm of Chartered Accountants in Norfolk, which were a top 30 firm of accountants at the time.

On qualifying, Simon moved to another firm of accountants, with five offices based in and around Peterborough.  At this time, Simon gained post qualification experience and training which made him the general practioner that he is today, but with a leaning towards the small owner managed businesses.

His experience included the preparation and audit of company statutory accounts, the preparation of partnership and sole trade accounts, together with personal tax return preparation and tax advice.  He also prepared management accounts for a number of businesses, providing insightful and timely information and advice to the owners.

Simon then gained further experience in “one office” practices, and so has a wide range of experience of how accountants are run.

In 2017, Simon decided to form his own practice, Simas Accounting & Tax, taking the best parts from the firms he had worked with previously.  His drive and focus is on meeting and exceeding the client’s expectations, providing them with peace of mind and timely advice.

April 2019 sees the last legally required increase to auto-enrolment pension contributions, seven years since they were introduced. But an employers’ role in helping staff to save for their retirement through the scheme is far from over.
