I'm running a limited company myself & there is mountains of paper work/ forms & admin dates that stuff has to be done by. (I have a company sec. for legal requirements only)

In order to try maintain an organized approach & delegate work to employees & get nic payment returns/corporate tax returns & paye sorted, I could do with some sort of legal / business diary that has like an "almanac" of important tax & business dates in it - does such a product exist with prefilled useful info ? 

- The sort thing ideally would be a large book with all the information from business link contained in it,  with blank space for notes relating to my own circumstances - (I'm not expecting any profit for atleast a year, food & logings are paid for, all employees are willing to go on commission only payments for first year) so basically I want to do as much of the paperwork as reasonably possible myself but have it in good enough order to hand over to an accountant if I need to)

Also, how much notice should an accountant be given in advance of accounts due date ?
