I did some work for another uni - just tutoring work, and was due about £500. I've been paid, but they've taken £100 in tax (or there abouts).

Now, cos I earn NOTHING I don't tend to pay tax (i.e. I earn undert my £6.5k threshold), I do have to do a tax return each year though, because I earn about £200 on self employed associate work.

is there any way I can get the £100 tax back before Jan 2012? which is when the tax return for this financial year would be in for?

Ring the inland revenue and see what they say. My boyfriend has just got a whole load of money back for overpayed tax, and I'm pretty sure that included the 09/10 period (so you shuold be able to get yours back after 04/11 - know that's a way away yet!) and possible up to the present. ANyway he said they were very nice and helpful on the phone.
