I'm about to trigger a pension (Civil service db)I wanted max monthly income so was going to take minimum lump sum. I assumed people who took big lump sums did so to pay off mortgage, buy cars etc. Am I missing a trick here? Should I take a larger lump sum (tax free) and pay myself out of it each month? I'd pay basic rate on my annual pension as I originally planned it to take it, Could I save on paying tax if I did this for the next few years? It seems too simple, is there something I'm missing?
