Capital gains tax

[Summerbubbles]

Does anyone know, if Rishi raises cgt as expected in the budget tomorrow, how quickly would it actually take effect? Would it be from April when the new tax year begins or would it be immediately?
I can't seem to find an answer anywhere.

Nobody knows until the budget- it will be announced then - anything you find before this will be pure speculation

It varies. Pension rules changed at 12 noon of the announcement last time. Sometimes we get notice.

Thanks for the replies, typically of my bad luck I have a house sale completing on Friday, so two days may end up being very costly.

Possibly, but house rates are already higher, you may get lucky!

Also they WANT you to sell so it pays to give notice. If I were Rishi, this would be fine!
