This depends mainly on how much money you take out and how your funds are performing.
Taking a higher income or a lump sum increases the risk of your fund running out sooner. So it may not last as long as you, and your loved one, need it to.
Taking money out might mean a change in the tax you pay. Tax rules can change and the impact of taxation (and any tax relief) depends on your circumstances.
Taking money out of your pension pot sometimes triggers a limit on how much can be paid into it in the future. Find out more about the Money Purchase Annual Allowance
Taking money out could mean certain state benefits that are based on your income or savings could be reduced or stopped. This applies to benefits like housing benefit or income support and if you have any debts, the creditor may have rights to any cash you take.
By increasing your income or taking a lump sum there will be less to leave behind to a loved one.
