If Congress does nothing to change the estate tax, on January 1, 2011, the federal estate tax law reverts to the 2001 law as it existed prior to the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA). As a result, the states will obtain the money they once received prior to EGTRRA. This is because EGTRRA repealed the state death tax credit which was fully phased out after 2004. This state death tax credit received by the states began in 1924 and survived with some adjustments until 2004. This credit was free money for the states and had no adverse effect on the residents of the states. Surprisingly, at the time of enacting EGTRRA there was no strong advocacy by the states and the credit was eliminated under EGTRRA.
In 2001, prior to EGTRRA, the state death tax credit was calculated as follows: an amount of $60,000 was subtracted from the taxable estate to obtain the adjusted taxable estate and with that figure the state death tax credit was calculated from a table as provided by the IRS. Generally an amount equal to the state death tax credit was distributed to the applicable state. Under EGTRRA the federal government reduced the estate tax rate but they receive more tax monies because of the elimination of the state death tax credit.
If Congress does nothing then on January 1, 2011, the states will receive this credit money again as the state death tax credit will be restored.
