selling a 2nd property

Matttdd

after selling a 2nd house I will have approx 90k in capital gains , less selling fees and a small amount of  maintenance  costs .I've been onto the gov website , I'm a standard rate tax payer .The amount calculated is approx £22k in CGT to be paid 
It does not allow any offset for me to put £20k into a cash isa which I've read will reduce the CGT payment as that's my limit for the year and will be tax free 
How do I alter the figures or inform them that I will be putting this £20k into a cash ISA 
thank you

Not sure where you read that, can you send a link?

If you hold Stocks and shares in an ISA, you are protected from any CGT on the gains on those, but you can not avoid CGT on selling a property by just adding cash to an ISA.

The only way to mitigate your capital gains tax liability is to crystallise a  loss on selling another asset. Whatever you've read doesn't ring true unfortunately.

I read you can pay the maximum yearly amount into a isa or transfer it into your pension fund

you are getting confused.  i think you can put a property into an isa or sipp but it isn't straightforward and that isn't to do with selling your property already and having to pay capital gains tax.

you have to pay the CGT.
