Tax refund questiom

If I paid CGT on some American stock I sold earlier in the year, would HMRC send me a income tax refund for this?

F*ck sent before I finished. 

I had no other employment at the time as I was a student and not working so just trying to work out where this would have come from. 

You might want to do a quick tax return  b4 the end of Jan if you want to be sure.
BTW, How much gain did you make, there is 12300 annual exemption don’t forget.
