2009 Federal Income Tax Brackets (Official IRS Tax Rates)

9/16/09: The inflation data for 2009 have been released, so you can find the 2010 income tax brackets [3].

2/26/09: These IRS tax brackets are official.

The Labor Department released inflation data yesterday [4] and the Wall Street Journal had three tax experts estimate how all the inflation-pegged tax figures would change based on those numbers. Many tax numbers, like the brackets, exemptions, standard deductions, etc., are pegged to inflation so knowing the Labor Department figures can give you huge insight into how those numbers will move. The three experts are George Jones, senior federal tax analyst at CCH; William Massey, senior tax analyst for the tax & accounting business of Thomson Reuters; and Prof. James C. Young, professor of accountancy at Northern Illinois University. The Wall Street Journal does this every year and, for as long as I can remember, they’re often it pretty spot on. Based on their calculations, a bunch of inflation-pegged tax numbers are going up.


All these figures are merely estimates, the government can always go back and adjust inflation figures so these numbers may change.
