When you die, the remaining value of your SIPP can be passed on to your nominated beneficiaries. You can nominate SIPP beneficiaries by completing a SIPP beneficiary or ‘expression of wishes’ form with your SIPP provider. Money in a SIPP can normally be passed on free of Inheritance Tax. Any withdrawals the beneficiaries make will usually be tax free if you die before the age of 75. If you die aged 75 or older, any withdrawals made by beneficiaries will be taxed as income.
