If you claimed EITC you would be in the second phase. The IRS news release that DoninGA referenced says "The first phase of adjustments is being made for single taxpayers who had the simplest tax returns, such as those filed by taxpayers who did not claim children or any refundable tax credits." EITC is a refundable credit. It makes your tax return more complex, regardless of filing status, because they have to recalculate the EITC as well as the unemployment exclusion.
