"You" don't owe any CT, and never did. The company of which your were a director might have owed CT, but that company no longer exists. End of story. Contrary to earlier replies, HMRC can and do sometimes ignore a striking off notice even when there is tax owing.
Just one thing though, when you say you have "set aside" money for the CT, do you mean your own money or company money? If company money then that now belongs to the treasury and you have no right to do anything with it other than surrender it.
