That’s only if you were sick and knew you were terminal. Without any prior indication of the impending death, what you give away is not considered touchable by the estate.
If I give my sister my stamp collection and then get hit by a bus tomorrow, it is not part of the estate.
My dad gave me his car several months before he passed, but we never transferred title. I did not count it as part of the estate, but as I understood the requirement, I paid inheritance tax on estimated value.
