Over the years there have been some consistent themes since my earliest years as a trainee - no-one has ever wanted to do P11Ds or annual returns - or to be the office VAT expert!
And I still hate doing P11Ds:
1. Because clients don't value them, and hence don't value our time doing them on their behalf - i.e you can't charge an adequate fee for all the hassle they are. One of my clients uses a big payroll bureau who charge just £7 per P11D! I'm not interested in competing with that!
