Bill
HB 2639
The bill standardizes and raises the general homestead exemption to a $10,000 maximum EAV reduction in all Illinois counties starting in 2026.
Status & sponsors
- Primary sponsor: Rep. Martin McLaughlin (introduced Feb 6, 2025).
- Co‑sponsor added: Rep. Kevin Schmidt.
- Bill amends the Illinois Property Tax Code (35 ILCS 200/15‑175). The text in the provided packet includes unrelated material from another state's bill (Arizona TPT language); this summary focuses on the Illinois Property Tax provisions.
Main purpose
- Standardize and raise the maximum general homestead exemption to $10,000 in all Illinois counties for taxable years 2026 and thereafter.
Key provisions
- Amends Section 15‑175 (General homestead exemption) to set the maximum reduction in equalized assessed value (EAV) for the general homestead exemption at $10,000 in every county beginning with taxable year 2026 and continuing thereafter.
- Removes the county population‑based variation that previously provided a $10,000 maximum in counties with 3,000,000+ residents and lower amounts (e.g., $8,000) elsewhere for certain prior years.
- Retains existing statutory mechanics for computing the homestead exemption (the reduction is measured against 1977 EAV baseline increases and subject to other subsections of Section 15‑175).
- Effective date language in the bill text indicates immediate effectiveness (the bill text states “Effective immediately”).
Who is affected
- Illinois homeowners who qualify for the general homestead exemption — especially residents of counties that previously had a lower maximum reduction (those outside the largest county/ies) — will potentially see a larger reduction in their taxable equalized assessed value.
- County assessors, treasurers, and local tax officials will need to implement the new uniform exemption level in assessment and billing systems beginning with taxable year 2026.
- Local taxing districts (school districts, municipalities, counties) could see changes in assessed bases and therefore in property tax revenues and rate calculations; the net revenue impact depends on how local levies and tax rate-setting respond.
Potential fiscal and practical impacts
- For individual homeowners: an increase in the exemption cap can lower taxable value up to $10,000, producing a proportionate reduction in property tax liability for eligible owners.
- For local governments and taxing bodies: the shift increases aggregate exemption amounts, which may reduce taxable bases and could result in higher tax rates to maintain fixed levies, or reduced revenue if levies are unchanged. The bill text does not include a fiscal note or explicit offsets.
- Administrative: county assessment offices must update exemption processing for 2026 and communicate changes to taxpayers.
Procedural / timeline notes (from provided materials)
- Illinois bill introduced in early February 2025 (LRB reference: LRB104 09751 HLH 19817 b). The synopsis and text specify the change applies for taxable years 2026 and thereafter and includes immediate effectiveness language.
- The legislative packet also contains unrelated Arizona transaction privilege tax (TPT) amendment language; that material does not relate to the Illinois Property Tax change described above.
If you want, I can:
- Draft a short explainer example showing how a $10,000 EAV exemption translates into tax savings at different local tax rates.
- Prepare likely fiscal questions for county assessors or a checklist for implementation by local tax offices.
