Thanks for all the advice guys. It's been invaluable knowledge for me! Turns out, after all, I don't even need to do a Self Assessment at the moment, since I have only been self-employed since April 2011. I wasn't aware that the Jan 31st deadline was for the Year 2010-2011! I take it that means I will be doing my self assessment in April then?
Yes, the deadline coming up if for the tax year ending in 4th April 2011 (why can't they make it easier by simply using the 31st Mar.
I'd definitely recommend getting an accountant, locally if possible so they are part of your "network".
Remember - yes you'll have to pay them but on the day you're paying them, you can be out working.
