A new paper from Citizens for Tax Justice shows that the 2006 tax bill of W and wife Laura was $31,037 lower than last year's bill. That's 14 percent smaller than the couple's prior year taxes.

No, the First Family didn't hire a new accountant. Instead, the Bushes can thank the president's own tax cut program.

24.4 percent of W's 2006 income went to taxes, according to CTJ. Without his tax cuts, he and his wife would have paid 28.4 percent of their earnings to the IRS.

Here are the figures, per CTJ, for the First Family:

And here's how CTJ says W's lower 2006 tax obligation breaks out:

• 3/4 of the Bushes' tax cut came from lower regular tax rates, 
• 1/6 came from the reduction, from 20 percent to 15 percent, in the the top tax rate for capital gains and dividends, and
• the rest came from higher phaseout limits on itemized deductions and personal exemptions.

Dick and Lynne Cheney got an even better tax deal. 23.4 percent of their 2006 income went to taxes, down from the 29.5 percent they would have paid without the tax cuts.
