I am currenty full time employed, and earn £27,000 PA Gross.
I would like to start my own company, initially running in parallel with my fulltime job, until I can be sure it's a profitable concern and take the jump to being self employed full time.
I would rather my current employer did not know I was going to go it alone, do they have to be informed of my 2nd income?
Does this automatically mean I will require self assesment?
Are there any good sites for clueless people like me? (I have always been full time employed, so never had to do self assesment).
Some collegues have suggested all my income from my 2nd job will be taxed at the 40% rate, is this true, or will I only be taxed at the higher rate for anything i earn over the threshold?
Thanks for any advice.
