The Income Tax and Charitable Contributions

Charitable contributions are an important source of basic finance for a wide variety of private nonprofit organizations that perform quasi-public functions. The tax treatment of charitable contributions substantially influences the volume and distribution of these gifts. The current study presents new estimates of the price and income elasticities of charitable giving. The parameter estimates are then used with the United States Treasury Tax File to simulate the effects of several possible alternatives to the current tax treatment of charitable giving. INDIVIDUAL CHARITABLE CONTRIBUTIONS are an important source of basic finance for a wide variety of private nonprofit organizations.

Critical to a resolution of these issues is an understanding of the likely quantitative effects of alternative tax rules: the effects on the total volume of charitable gifts and its distribution among the different types of donees; the effects on the distribution of tax burdens
