Preemption is a doctrine of American constitutional law, under which states and local governments are deprived of their power to act in a given area, whether or not the state or local law, rule or action is in direct conflict with federal law. This book covers not only the basics of preemption but also focuses on such topics as federal mechanisms for agency preemption, implied forms of preemption, and defensive use of federal preemption in civil litigation.

The Tax Foundation's State Business Tax Climate Index enables business leaders, government policymakers, and taxpayers to gauge how their states' tax systems compare. While there are many ways to show how much is collected in taxes by state governments, the Index is designed to show how well states structure their tax systems, and provides a roadmap to improving these structures.
