If the amount of your state pension is more than the personal allowance, it will be taxed. My IFA confirmed this to me.
The personal allowance is £12,570 though, and state pension is £203.85 per week, (£10,600pa) from April, so if you survive on the state pension alone you won’t have to pay tax. The only circumstances I can think of where it would apply is if you have a long deferred pension which had increased your rate above the tax threshold, but that wouldn’t apply to many people. I’m sure there are tax experts on here who know much more about this though.
