New York Times:  In Obama’s Plan to Tax Rich, $250,000 Figure May Mislead:

President Obama’s insistence that marginal tax rates rise for families making more than $250,000 has convinced millions of affluent Americans that they are likely to be writing larger checks to the government next year. 

But many of those families have no reason to fret.

A close look at the president’s plan shows that a large majority of
families making up to $300,000 — as well as hundreds of thousands of
families with even larger incomes — would not pay taxes at a higher
marginal rate.

Because the complexity of the tax code makes it difficult to draw clean
lines, they are the beneficiaries of choices the administration has made
to ensure that families earning less than $250,000 do not pay higher
rates.

New York Times: When $250,000 Isn’t Actually $250,000:

[T]here are lot of couples earning more than $250,000 whose tax liability would not be affected. There are two main reasons: inflation, and the very narrow way income is defined in this proposal.
