I do work for two different Universities on an as and when basis, and also do stuff through peopleperhour. I pay tax already on the University jobs, but when I started with PPH registered for self assessment. I'm a bit confused now - I take it I declare all of the above, despite the fact I've already paid tax for the university work (I get a payslip)? How then does it work so that I don't pay tax twice??
Help!!
Thanks
