I know a several families that have passed large estates to their heirs. None have paid estate tax. Getting rid of that tax is just a "feel good" thing. If you have a large estate, get an estate attorney now.
Good point, thank you for mentioning it! Sadly, some people didn't get theirs or didn't know to get an estate attorney, and still lost their beautiful property.
Ever seen the musical "Oklahoma"? That was actually filmed right here in Southern Arizona (Sorry, Oklahoma!) On the Sharp's Ranch. The Sharp's Ranch was a huge, beautiful ranch that had been handed down through their family for generations. Sadly, they lost it when Mrs. Sharp died and they couldn't afford the taxes. So the government got it. Now it is "San Rafael State Park." Makes me sad, actually.
