Hi
The level of fee which an accountant charges is simply based on the time it takes to complete the assignment. You have not given enough information to say whether you have been overcharged or not. What is the level of turnover, what type of industry, are you a limited company, did you require an audit done etc
The accountants are prepare for an accounting year and do not follow the fisical tax year. It sounds to me that you dont really understand the work that your accountant does and perhaps you should arrange to meet him and discuss it with him further.
Kind Regards
