IL HB4561

Allows property taxpayers to pay property taxes under protest in installments for tax years 2024 and 2025 if the current year's tax liability exceeds the prior year's liability.

Taxpayers owing more in 2024 or 2025 than the previous year must pay 100% of the prior year's tax liability plus 50% of the increase, rather than the full amount due.

Requires taxpayers making partial protest payments to file a separate letter of protest with the county collector and notify them at each stage of the property tax appeal process.

The Department of Revenue must create standard forms and notices for taxpayers to use when making partial protest payments and when notifying the county collector of appeal status.

Properties with taxes paid under protest (in full or in part) shall not be included in tax sale lists.
