I retired from my job in August 2024. I had submitted all necessary documents for the state pension. I have received a letter confirming that I am eligible for 1. State Pension 2. Additional State Pension 3. I can have a lump sum amount of if I accept to forego my Additional State Pension. I have retired from NHS and have a small NHS Pension also. I have been trying to enquire from HMRC (and DWP also) whether the lump sum I receive will be taxable or not (and how much tax will be due if lump sum will be taxed) I have talked to more than 8 advisors in HMRC. But no one has provided me any information which provides an accurate clarification regarding the above? It would be greatly appreciated if anyone can provide any insight and let me know if the lump sum will be taxable or not? And if the lump sum will be taxed, how much is it likely to be taxed i.e. which tax bracket is it likely to fall under?
