Hi, I've just tried to defer my student loan for another year but I'm missing some evidence apparently. They do not tell you online what evidence you are missing, you have to wait for a letter. Well, I've been waiting weeks, so I'm trying to guess what it is! It's the first year I've done a tax self assessment form, can anyone please advise me of the name of the form that it wants as evidence for this? Whatever I've sent is not sufficient and I don't know what to ask the accountant for. Many thanks.
