a. Taxable income exceeds the thresholds due to income of a spouse.

b. Taxable income did not exceed the thresholds in the prior three years.

c. Taxable income exceeds the thresholds because of net capital gain income.

d. The taxpayer is a sole proprietor.

e. None of the above will prevent the loss of some or all of the deduction.
