Have you researched the estate tax at all?
There are several credits against the tentative tax, the most important of which is a "unified credit" which can be thought of as providing for an "exemption equivalent" or exempted value with respect to the sum of the taxable estate and the taxable gifts during lifetime.
For a person dying during 2006, 2007, or 2008, the "applicable exclusion amount" is $2,000,000, so if the sum of the taxable estate plus the "adjusted taxable gifts" made during lifetime equals $2,000,000 or less, there is no federal estate tax to pay. According to the Economic Growth and Tax Relief Reconciliation Act of 2001, the applicable exclusion increased to $3,500,000 in 2009, the estate tax was repealed for estates of decedents dying in 2010, but then the Act "sunsets" in 2011 and the estate tax was to reappear with an applicable exclusion amount of only $1,000,000. However, On December 16, 2010, Congress passed the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010, which was signed into law by President Barack Obama on December 17, 2010. The 2010 Act changed, among other things, the rate structure for estates of decedents dying after December 31, 2009, subject to certain exceptions. It also served to reunify the estate tax credit (aka exemption equivalent) with the federal gift tax credit (aka exemption equivalent). The gift tax exemption is now equal to $5,000,000.
Let's look at that again. The gift tax exemption is now equal to $5,000,000.
