Few interesting topics around on this part of the site Generally, there are some guys that know their stuff when it comes to taxation/NI, but a lot don't. I would imagine that there are some guys who don't realise they should be claiming back tax at all. Generally speaking the self employed will have an accountant of some sort. They should be able to deal with their issues. For those that don't we could either have a) a detailed wiki page on all the tax issues with contacts for HMRC etc b) look at the possibility of setting up a service whereby TA people can send in their tax documents etc. and have their tax returns done for them by someone who is qualified (for example I know that as well as myself there are a few other accountants and chartered accountants on here). The problem with that is there would be a cost involved - which would probably wipe out anything you would get in returned tax anyway. c) a separate board/something in the FAQ section showing some of the previous answers Anybody want to start a wiki page and stick a link on here? If so, I don't mind popping over and seeing if I can add anything to it later.
