Hiya, I had a little look because im sure it has been asked before but basically a question about what I am going to be taxed, my tax code is 522l which I understand means I am allowed 5220 pounds without tax a year (except N.I, what is the rate N.I is charged at btw?) but after the 5220 pounds I am wondering what the tax is charged at, will be earning under 20k as its a training position, Thanks!!
bloody tax tbh 

I havnt done my calculations actually, not sure.
