New income tax rate table for 2012 (inflation adjustment) has been released by the IRS on Thursday (October 20, 2011) and it’s effective in the beginning of 2012. The income tax rate tables came with revenue procedure, and many adjustments on tax credit. I plan to post the tax credit adjustment item later.
