Countdown begins
I think you may be a bit muddled with your logic? AFPS15 is 1/47th so will not decrease, but increase, your Pension Input Amount (PIA). So reverting to AFPS05 at 1/70th could well reduce your PIA. However, I believe that few get close to the Annual Allowance maximum of £40k with AFPS15 or AFPS05 - it is usually the AFPS75 lurking in the background that is the killer. That is my understanding anyway - and I’m happy to be proved wrong!
