All states have tax provisions to encourage particular land uses and to provide property tax relief to selected classes of owners. Property tax relief and incentive programs are grouped here according to their objectives and structure. They include tax relief to residential property owners, provisions to encourage economic development, to reduce taxes on certain types of property (e.g., agricultural or open space), and programs to encourage specific types of property improvement. They may offer relief by applying a different value standard (e.g., use value) or through exemptions, credits, or deferral of payments.
