Passage Three
The traditional appeal of the income tax has come from its wide acceptance, as a fair tax, closely related to an individual’s ability to pay. For many years the income tax provided large federal income without imposing heavy burdens on the great majority of people. By the mid-20m century, however, serious criticisms of tax loopholes were heard. Concerted attempts at reform resulted only in a more complex and eroded tax base. The situation worsened in the 1970s, as rising inflation pushed people into higher tax brackets although their incomes were barely keeping pace with rising prices. This pressure further eroded public confidence in the fairness of the income tax; at the same time it created strong incentives to utilize tax shelters and other loopholes, as well as to conceal off-the-record income. Built-in inflation adjustments were adopted, first by a number of states and then in 1985 by the federal government.
Income tax policy is in
A. Off-the-record income
B. Self-employment earnings
C. Business earnings
D. Income from charitable activities
