John Cotter CTA ATT ICPA
Hi, I ‘m John and I founded T4 in its original form as “The Thames Valley Tax Practice” in February 1989.
In 2004 we incorporated as T4 Tax Limited.
Over the last 35+ years I have dealt with a very wide range of tax, accounting and business issues for small, medium and large businesses.
Our speciality is small and medium size businesses with turnovers up to around £2Million.
I have dealt with people from all walks of life over the years, from the rich & famous, to the rest of us morals. My goal is to treat everyone equally and give, practical, efficient, and effective advice to all our clients.
Our teams constant goal for T4 is to be “best in class” and “ahead of the rest”. We work hard, and diligently, to achieve that goal.
Our client focused approach means we rarely lose clients and as a consequence space for new clients can at times be limited. We don’t want our growth to impact on the quality of service to our clients. Without our clients and our great team we simply would not exist.
For new client availability see our clients page.
Approx. 150 Valued Clients
At T4 Tax Limited we have around 150 clients and we grow year on year.
We treat every client with the same personal level of focus, help and support from small clients to large clients, existing ones, and new clients.
Some of our clients have been with T4 for over 35 years and many since the day they first went into business.
We have grown significantly in the last few years.
