Miscellaneous Deductions Reported on Schedule A

Not all personal deductions to which you are entitled fit neatly into a category broken out on Schedule A, such as medical expenses, tax and interest payments, charitable contributions, or casualty and theft losses. All other allowable deductions that must be itemized on the return are called "miscellaneous itemized deductions." There are two categories of miscellaneous itemized deductions:

Miscellaneous itemized deductions (other than gambling losses) are subject to reduction for high-income taxpayers. This means part of the otherwise allowable deductions cannot be claimed.

All miscellaneous itemized deductions are disallowed when computing the alternative minimum tax. This means that even if you write off miscellaneous itemized deductions for regular tax purposes, you lose any benefit from them if you are subject to the alternative minimum tax.
