Yorkville Caps Residential Property Tax Growth at 2 Percent Annually

The Yorkville City Council passed the Property Tax Stabilization Ordinance on July 7, 2026, which sets a 2 percent annual cap on increases to assessed values for residential properties. The measure applies to single-family homes and applies directly to how the county assessor calculates bills sent to Yorkville residents each spring.

Local government records show that property assessments in Yorkville rose an average of 5.8 percent last year, driven by recent sales data compiled by the Yorkville Assessor's Office. The new ordinance responds to that trend by tying future assessed values to the cap rather than full market changes.

Effects on Household Payments

Under the ordinance, a home assessed at $320,000 in 2026 would see its taxable value rise by no more than $6,400 in 2027. That adjustment translates into roughly $85 less in added property tax for a household paying the current Yorkville millage rate of 13.4 mills. Residents who heat with natural gas or rely on fixed incomes will see the change reflected in their March 2027 tax statements.

The city budget office projects that the cap will hold total residential property tax collections at $48.2 million for fiscal year 2027, compared with the $51.1 million that would have been collected under uncapped assessments. The difference stays within the existing general fund without new fees or service cuts.

Next Steps for Implementation

City staff will send updated assessment notices by October 15, 2026, and the county treasurer will apply the cap when printing 2027 bills. Property owners can file appeals with the Yorkville Board of Review if they believe their individual assessment exceeds the 2 percent limit.

The ordinance expires after two years unless the council votes to extend it before December 2028. Council documents state that renewal will depend on updated sales data from the assessor and any changes to state aid formulas that affect Yorkville's revenue.
