I have earned just over the 50k threshold for 2022-23, £50054. The self assessment has come back as saying I owe £339.00. Anyone know if this seems correct? I think it seems high for being just slightly over. I stupidly helped my work out by doing an extra shift in March, I would have been under the 50k otherwise! The helpline is closed till September so I can't speak to anyone to ask.
