"Is it true that an estate tax has been imposed (or maintained) every time our country has gone to war, until GW Bush's administration? "
The estate tax has been in existence for every year since 1942 (w/ the single exemption of 2010). It's enactment or collection has nothing to do w/ wars.
"What is the percentage of people in the US that would be subject to the "death tax" if it is re-imposed?"
Not sure the % but remember first $1 mil is exempt. So if you die and your estate is worth $200K = $0 in taxes. $800K = $0 in taxes. $1.1 million = only the "last" $100K is taxed.
Also the tax rate is graduated.
For amounts not greater than $10,000, the tax liability is 18% of the amount.
For amounts over $10,000 but not over $20,000, the tentative tax is $1,800 plus 20% of the excess over $10,000.
For amounts over $20,000 but not over $40,000, the tentative tax is $3,800 plus 22% of the excess over $20,000.
For amounts over $40,000 but not over $60,000, the tentative tax is $8,200 plus 24% of the excess over $40,000.
For amounts over $60,000 but not over $80,000, the tentative tax is $13,000 plus 26% of the excess over $60,000.
For amounts over $80,000 but not over $100,000, the tentative tax is $18,200 plus 28% of the excess over $80,000.
For amounts over $100,000 but not over $150,000, the tentative tax is $23,800 plus 30% of the excess over $100,000.
For amounts over $150,000 but not over $250,000, the tentative tax is $38,800 plus 32% of the excess over $150,000.
For amounts over $250,000 but not over $500,000, the tentative tax is $70,800 plus 34% of the excess over $250,000.
For amounts over $500,000 but not over $750,000, the tentative tax is $155,800 plus 37% of the excess over $500,000.
For amounts over $750,000 but not over $1,000,000, the tentative tax is $248,300 plus 39% of the excess over $750,000.
For amounts over $1,000,000 but not over $1,250,000, the tentative tax is $345,800 plus 41% of the excess over $1,000,000.
For amounts over $1,250,000 but not over $1,500,000, the tentative tax is $448,300 plus 43% of the excess over $1,250,000.
For amounts over $1,500,000 but not over $2,000,000, the tentative tax is $555,800 plus 45% of the excess over $1,500,000.
For amounts over $2,000,000 but not over $2,500,000, the tentative tax is $780,800 plus 49% of the excess over $2,000,000.
For amounts over $2,500,000 but not over $3,000,000, the tentative tax is $1,025,800 plus 53% of the excess over $2,500,000.
For amounts over $3,000,000, the tentative tax is $1,290,800 plus 55% of the excess over $3,000,000.
Remember the "amount" is AFTER the $1 mil exemption.
So someone with an estate of $2 mil would have $1 mil taxed and the taxes owed would be $248,300 for a total tax rate of ~12%.
http://en.wikipedia.org/wiki/Estate_tax_in_the_United_States"What are ways that the rich "get around" an estate tax?"
Not really which is why the rich hate it. Personally I would prefer a higher rate but offset by a higher exempt amount. Say first $5 million exempt then after that the rate is 25% - 70% (progressively graduated).
Some things aren't taxed. Life insurance for an example isn't part of the estate. It is paid directly to beneficiary thus isn't part of death tax. Pensions w/ survivor benefit are same thing as are 401K/IRA (if beneficiary is named).
