This online database presents data on the property tax in all 50 states and the District of Columbia. Because accurate data provide the critical foundation for sound governmental decision-making, the Lincoln Institute of Land Policy and the George Washington Institute of Public Policy joined in a partnership to provide information and support public policy concerning the property tax, probably the most controversial tax in the United States. The term "Significant Features" pays tribute to the work of the Advisory Commission on Intergovernmental Relations, which from 1959 to 1996 provided a wealth of research on the functioning of the federal system, particularly through its flagship publication, Significant Features of Fiscal Federalism.
