Tax rebate deadline ?

I have been told I am due a tax rebate ( on the phone with HMRC) for 23/24 tax year . When will I recieve this? I have had no P800 yet or any communication about it.

Hi Sharon Lee,
If your overpayment of tax has been calculated, you should be able to see it, and claim it via your Personal Tax Account (PTA)
You can access your PTA here:
Personal tax account: sign in or set up
If your overpayment is not present, we may be waiting on more information about your income for the 23/24 tax year.
Please contact us by webchat or phone here:
Self Assessment: general enquiries
So we can update you further.
Thank you.
