IL HB2512

Amends the Property Tax Code Section 12-55 to require county assessors in counties with 3,000,000 or more inhabitants to accept taxpayer appeals for a minimum of 35 business days from the later of when the assessment notice is mailed or published on the assessor's website.

Applies this 35 business-day appeal period specifically to assessor revisions that are not made on complaint of the property owner.

Maintains existing requirements that assessors provide notice to taxpayers before increasing assessments and allow opportunity to be heard before verification.

Preserves existing provisions regarding mortgagee notification and filing of complaint lists with the board of review, with no changes to those procedures.
