Opening a new pension fund from sale of second property

I am due to sell an house soon if things go ahead and my CGT gain of around £100,000 will create a CGT bill of circa £20,000 with the majority being taxed at the higher rate of 24%. My income moving forward will be circa £26,000, if I open a new pension fund, how much can I offset the sale of the properties CGT to reduce the rate to 18% please.

Hi

HMRC cannot advise you on this as it is financial advice which we are not authorised to give.

Thank you

I rang HMRC this morning and the really helpful person I spoke to has answered the question.
