@sportyfae and HMRC Admin, thanks for your replies - it all makes sense now. Seems like my eagerness to get any tax issues out of the way was the problem then. this is the first time I've had to do this (self assessment) so will know better if there is a next time.
Thank you all again. :)
I hope someone can clarify this for me as this year is the first time I've hit a payment threshold which meant I needed to do a self assessment. (I'm an employee, and only source of income is from my job)
Having filled out my self-assessment, the end result was that it said I owed X thousand pound which I've paid.
However a couple of weeks later I got a letter suggesting I should check my status online, and when I did, it said I'd overpaid, and was now due repayment, but the UI also still says X is due. For example, UI shows as follows:
You have overpaid. £X is available for repayment.
Request a repayment
£X will be due for payment and a breakdown of this amount and when this needs to be paid by is outlined in the table below.
(with due date noted as 31 Jan 2024)
So my question is which is right? Should I request a repayment as this might have been an overpayment or is it just a quirk of how the system is setup and I shouldn't request a repayment as the amount is still owed?
I hope the above makes sense, and thank you in advance
