Top 10 of 1,908 law firms for Self Assessment Tax Returns, Money & Tax

Law firms ranked by client reviews

This area covers individuals’ annual Self Assessment tax returns with HM Revenue & Customs, including reporting earnings, investments and other income, capital gains, and claimed reliefs. A solicitor helps prepare and file the UK Self Assessment return (the SA100) and any supplementary pages, verifies figures, and advises on penalties, deadlines, amendments, and how to respond to HMRC inquiries or investigations. The work is shaped by tax rules, deadlines and potential HMRC checks.

Where a solicitor protects your position

The specific act is the timely submission of a complete return and accurate figures; penalties, interest and additional tax can follow if deadlines are missed or details are wrong. A solicitor’s involvement provides structured handling of deadlines, accuracy checks, and proper responses to HMRC, reducing the risk of escalation by authorities.

Carly  Neville

Tagged solicitor Carly Neville

I used The MPP to undertake the probate application for my late father’s estate, as the firm had already done some work for my parents. I am so pleased that I turned to them, as I did not feel I was able to cope myself, and Carly was reassuring and capable at all times. She handled all my queries and was sympathetic throughout. She was also able to advise when I was being hounded by the tax office! I was very grateful for her support and professionalism when I was finding the matter hard to deal with. I was also impressed by her clear communication.
