How to claim a tax refund for deceased person

My mother died in June 2023 and as executor of her estate I informed all the authorities via the Tell Us Once service. She received 2 personal pensions in addition to her state pension and paid tax. She also received interest on her savings. How do I find out if a refund is due for the 2023/24 tax year and when this will be paid please?

Hi,
To confirm if a repayment is due and how to refund this to you, we would need to review your mother's record. To allow us to do this, please contact our Income Tax team.
