Important news from Seddon Smith

In reviewing the way forward to aid with the ongoing development of the practice, we have joined forces with Haines Watts, part of a group of accountants specialising in similar work to ourselves.   Haines Watts have been operating successfully in High Wycombe for over 30 years, providing a partner led accounting, tax and business advisory service to owner managed businesses.  Since 2015, Haines Watts has also had a presence in Hertfordshire following two mergers in Berkhamsted.  Haines Watts are now the largest provider of accounting and tax services to SME’s in the UK.


As of 9th February 2017, we merged to become Haines Watts Aylesbury. 


However, please be assured that little will change, apart from our name, as the team will remain exactly the same and will continue in their current roles based here in the same office.  We will continue to help you as we have done in the past at the same agreed levels of pricing.


We will also have the advantage of help from Shaun Brownsmith, one of the partners in Berkhamsted, as he lives in Aylesbury.  In addition, we will have access to the resources of both the High Wycombe and Berkhamsted offices, with staff numbers totalling in excess of 50 people, should these be required. We are sure that we will benefit from the extra resources in specialist areas such as fund raising, technical accounts back up, tax planning and consultancy, VAT, and corporate finance.


We will be in touch with as many of you as possible over the next few weeks to offer re-assurances that very little is going to change.  If you have any questions, please do not hesitate to call – the same number and of course the same address.

2016 Tax Returns - We did it again

We are pleased to say that once again, all of the Self-Assessment Tax Returns were filed on time.  This year (2016), we had more tax returns to file than ever before, but we were able to keep up our record of filing 100% by the deadline - a record that we have maintained every year since the introduction of Self-Assessment.

We would like to say ‘Thank You’ to all of our clients who provided us with the relevant information in time, thereby ensuring that none of our clients receive penalties.

25 Years of Seddon Smith

2016 marks the 25th anniversary of Seddon Smith.


The firm was set up by David Seddon and Andrew Smith in 1990 and commenced trading on a full-time basis in 1991.  Throughout the years we have been based in Aylesbury, Buckinghamshire, but our client base is far reaching, with clients throughout the UK and across into mainland Europe.  Some of our clients have been with us from the very beginning.


Of course, our personnel has undergone changes from time to time, but still working alongside David we have Penny, who has been with the firm for 24 years, and Sara and Seymour who have both recently reached 20 years service.


We thank you all for your support over the years and look forward to continuing to work with you for many years to come.

Emails from HM Revenue and Customs

You may have received one or more e-mails recently, purporting to be from HM Revenue and Customs or a similar tax authority (even some overseas tax authorities). Some of these refer to under-declared income, whilst others state that you are due a tax refund. They may look quite genuine, with the Revenue’s logo in the corner. However, they are all scam e-mails and in most cases ask you for either your personal bank details or your Revenue username and password.

HM Revenue and Customs NEVER uses e-mails either to advise of a repayment or to ask you to fill out an online form to receive such a repayment. If you receive such an e-mail please do not open it or complete any of the details asked for within it. The advice from the Revenue is to forward the e-mail to them at and they will let you know of any further steps to take.
