Middle Class Tax Relief Act - Amends the Internal Revenue Code to: (1) increase the maximum allowable dollar amount of the dependent care tax credit; (2) increase to $60,000 the adjusted gross income threshold for the phaseout of such credit; (3) allow such credit for the expenses of caring for the taxpayer's parents (or ancestors of such parents) who are unable to care for themselves; and (4) extend the additional standard tax deduction for state and local real property taxes through 2010 and increase the allowable amount of such deduction.
Makes permanent the increases in the dollar limits for the dependent care tax credit enacted by the Economic Growth and Tax Relief Reconciliation Act of 2001.
