IL HB4106

Extends the petition period for referendums on Tax Increment Allocation Redevelopment (TIF) bond issuance from 30 days to 45 days after ordinance publication in non-home rule municipalities.

Changes signature requirements for referendum petitions from 10% of registered voters to the greater of either 7.5% of registered voters or the lesser of 200 voters or 15% of registered voters.

Applies referendum requirements to all TIF obligations issued by non-home rule municipalities, rather than only those secured by the full faith and credit of the municipality.

Removes the exception that previously excluded certain TIF obligations and tax pledges from referendum requirements.

Takes effect upon becoming law, with referendum changes applying only to ordinances adopted after the effective date.
