The Crown Estate is not the personal property of the monarch, it's essentially just government assets. Who is the Crown Estate going to pay taxes to, itself?
Here is a better discussion of the details around the queen's estate tax exemption: https://www.townandcountrymag.com/society/money-and-power/a3...
Pretty ingenious way to allow "families to pass wealth from generation to generation, indefinitely, without estate taxes at each death". The UK should do something about that. I hear significant estate taxes are important to a democracy to prevent the rise of a noble class.
I'm curious if anyone knows how or why The Duchy of Lancaster[2] was not included in the The Crown Estate?

(and yes obviously the hereditary monarchy and peerages do not belong in the modern era let alone the 21st century, but changing that in a not especially democratic country is hard)
