Marriage Allowance on pension

I have been retired about 15 years. My only personal income is state pension which for the year 2022 -23 came to £13,240. I am married. I can’t remember but l think l claimed Marriage Allowance when working to enable me to share my tax relief with my non-income generating wife. As my wife was a foreign national before marriage and did not have uk income, she did not have any PAYE credit. As such, the only pension she gets is a small one based on my NHI contributions. My query is: How can I tell if the marriage tax allowance sharing continues now that l am just a state pensioner and, if it does, can I offset part of my state pension income to my wife, in order to reduce my personal tax liability

Hi Bill Fowler,
We would need to access your record to check if the Married Couples Allowance was claiimed.
