Relates to the determination of adjusted base proportions in special assessing units which are cities

This bill changes how cities calculate property tax base proportions for their special assessing units in the 2025 fiscal year. It requires local city councils to decide the percentage increase for these proportions, but limits that increase to a maximum of five percent and sets a deadline of November 1, 2024, for the decision. If tax bills were already sent out before the law took effect, cities must issue amended bills to reflect the new calculations while ensuring taxpayers do not owe more for installments that were already due. The changes apply immediately to cities with special assessing units that have not yet finalized their 2025 tax rates.
