I've had a text from HMRC stating that my tax refund is being processed and will be sent in the post within the next 6 weeks but no further details.
I've checked my 24-25 details and I paid £8091 in tax, when I compare this to the HMRC calculator for the same annual salary it looks like I should have paid £7514.
Does this mean that the refund could be as much as £577?
