Tax Preference Item
What it is:
How it works (Example):
According to U.S. tax code (26 USC section 57), there are several tax preference items, including:
• Intangible drilling costs
• Net income from oil, gas and geothermal properties
• Interest on specified private-activity bonds reduced by any deduction (not allowable in computing the regular tax) which would have been allowable if such interest were included in gross income
Generally speaking, these items are tax-exempt, meaning that investors can deduct them from their taxable income and thus lower their tax bills. However, if an investor is subject to the AMT and the amount of these deductions exceeds a certain percentage of the taxpayer's income, the investor must add these items back to his or her taxable income to compute the amount of tax owed (thus creating a higher tax bill).
Why it Matters:
Tax preference items are part of a larger strategy to ensure that taxpayers do not abuse deductions and tax shelters in order to minimize taxes owed. This is the onus for the alternative minimum tax, and the government's designation of tax preference items is intended to help accomplish that strategy.
