7662 / Is tax-exempt interest treated as an item of tax preference for purposes of the alternative minimum tax?

The answer is generally no. However, except as noted below with respect to private activity bonds issued in 2009 and 2010, tax-exempt interest on private activity bonds other than qualified 501(c)(3) bonds is a tax preference item for both the individual and corporate alternative minimum tax (prior to 2018, the corporate AMT was repealed for tax years beginning after 2017, see Q 777). The interest may be reduced by any deduction not allowable in computing regular tax that would have been allowable if the interest were includable in gross income (e.g., amortizable bond premium).¹ The preference item includes exempt-interest dividends paid by a mutual fund to the extent attributable to such interest.²
