The amount changed this year to $11,000 but remember that that counts against the one time exclusion ( which is usually what they leave in their will upon their death). That amount is something like $600,000 each for husband and wife meaning a total of $1,200,000 if they both die at the same time. It gets complicated when one dies, leaves everything to the surviving spouse and then they die with all the assets.
Of course in most families as with mine the chances of leaving over the $600,000 limit is not real good. However, this could be a problem with some families. Also the tax is charged to the estate of the person giving the money, not the receiver.
