Bush tax cuts: $458 billion. The package would extend the Bush tax cuts for everyone for two years, including two years of relief for the middle class from the Alternative Minimum Tax. The estimated cost would be $458 billion, according to earlier numbers from the Treasury Department. The bulk of that cost -- $383 billion -- is for the extension of cuts for families making less than $250,000. The rest -- roughly $75 billion -- is attributable to the extension of cuts that apply to the highest income families.
The cost of extending all the tax cuts over 10 years would have been $3.7 trillion.
