HB 5086 Illinois House · 104th Regular Session

PROP TAX-TWP ASSESSMENT BOOKS

Summary
Amends the Property Tax Code. In provisions concerning township or multi-township assessment books, provides that, if the supervisor of assessments determines that the township or multi-township assessor has not completed the assessments as required by law before returning the assessment books, then the supervisor of assessments (rather than the county board) may submit a bill to the township board of trustees for the reasonable costs incurred by the supervisor of assessments in completing the assessments. Provides that, if the supervisor of assessments determines that the township or multi-township assessor has provided incomplete books or workbooks within the prior quadrennial assessment cycle, then the supervisor of assessments may give notice to the township assessor or multi-township assessor and shall receive the assessment books or workbooks up to 90 days in advance of the deadlines if either (1) the township or multi-township has omitted new construction in the prior year for more than 6 months; or (2) at least 20% of any property class fails to be changed in the township or multi-township assessment books in the prior general assessment year. Provides that, if the supervisor of assessments determines that a review of the books of the township or multi-township is necessary, then the year the review takes place, the revaluation powers of the supervisor of assessments shall be the same as in the general assessment year and the supervisor of assessments shall have the authority to value omitted property. Provides that, if any valuation changes occur as the result of the provisions, then the county treasurer shall keep a list of the properties identified by the supervisor of assessments on the county's website. Provides that, if the township maintains a website, then the information shall be posted on the township's website. Effective immediately.
