What is the rule regarding taxation set by the Illinois Constitution?

The rule regarding taxation set by the Illinois Constitution states that taxes must be levied uniformly and cannot be discriminatory. This principle ensures fairness and equity in the taxation system, meaning that similar properties or individuals in similar circumstances should be taxed at the same rate. This uniformity helps to prevent arbitrary treatment and potential discrimination against certain taxpayers, creating a more just taxation framework within the state.

The other options present concepts that do not align with the principles of taxation outlined in the Illinois Constitution. Taxation related to specific types of properties, income-based exemptions, or localized determinations would not provide the broad, equitable treatment that the constitutional requirement for uniformity aims to uphold. This uniform taxation principle is essential for maintaining trust in the tax system and ensuring that the government can effectively and fairly fund its operations and responsibilities.
