Having paid well over the required Tax for 2023/24,due to also taking a private pension drawdown, i am due a PAYE tax refund. I have double confirmed this, using Gov.uk tax calculation tool. HMRC have all needed amounts / figures/ information (as i can see all this info that's required, on my HMRC mobile app), but i still see the dreaded "your tax has not been calculated yet", on the online gov.uk website. I thought that the P800 "tax calculation letters" were sent out by End of NOVEMBER, at the latest !!!!
