2022 - 23 Income Tax too high

I retired in December and my works pension is now my sole income. My online Income Tax estimate correctly records that I am receipt of a pension and have no current employment. However, it then states that my estimated income is approximately £97K, and not my pension income total. I have a tax code of SD1 with no Personal Allowance which is resulting in £800 of excess tax being deducted each period. Should this eventually resolve itself before the end of this tax year, which could result in a £10K tax overpayment, or is there any proactive steps I can take to get the situation corrected. Any advice or guidance would be greatly appreciated.

Hi,
 

When viewing the income tax estimate, if you are able to update the pension income this may correct the code. However if the estimate is including employment income that has ended, we may still have this set as your primary income and you would need to contact our helpline to amend this. See link: Income Tax: general enquiries     . Thank you.

Thanks for your response. I have tried to update my annual pension income with the April increase in the HMRC app but when checking after a few days, the original amount still shows. I’ll phone the helpline number in the link you provided and see if the issue can be resolved via that route. Thanks again.
