Question: I am 62 and plan to retire next year. I am going to receive a pension from my employer but I also have a separate self-employed personal pension (SIPP) which I want to take money from as well.

Can you tell me what I need to think about. I understand I can take 25 per cent of my pension and not pay any tax on it. Is that right? Should I take it all at once or can I stagger it? I want to use it to repay some debt and would probably put the remainder in an ISA.

Answer: From the age of 55 (rising to 57 from April 2028) you can take a quarter of your pension pot as a tax-free lump sum and either take the rest as a taxed lump sum, move the remainder to drawdown, or buy an annuity (which gives a set out guaranteed income for life). If you decide on drawdown, you can withdraw a taxable amount any time you want and how much you want.

You must have enough ‘lump sum allowance’ (LSA) left to take a tax-free lump sum – this is usually initially set at £268,275 and will include any tax-free cash sums you take from other pensions, such as your workplace pension.
