Middle Class Tax Fairness Act of 2012 - Amends the Internal Revenue Code to make permanent the taxpayer election to deduct state and local general sales taxes in lieu of state and local income taxes. Requires an individual taxpayer whose adjusted gross income exceeds $1 million to pay a minimum tax rate of 30% of the excess of the taxpayer's adjusted gross income over the taxpayer's modified charitable contribution deduction for the taxable year (tentative fair share tax). Establishes the amount of such tax as the excess (if any) of the tentative fair share tax over the excess of: (1) the sum of the taxpayer's regular tax liability, the alternative minimum tax (AMT) amount, and the payroll tax for the taxable year; over (2) certain tax credits. Provides for a phase-in of such tax. Requires an inflation adjustment to the $1 million income threshold for taxable years beginning after 2013. Requires any savings resulting from the enactment of this Act to be used for federal budget deficit reduction or reduction of the federal debt.
