Joliet homeowners who occupy their home as a primary residence should review the exemptions shown on the property tax bill. The Will County Supervisor of Assessments administers assessment and exemption information, while the Treasurer handles billing and payment questions.

Look at the exemption lines on the tax bill

Compare the current bill with the prior year and check the exemption section. A change after a move, death, ownership transfer, or change in occupancy deserves a question to the appropriate county office.

Know the difference between common exemptions

Will County lists General Homestead, Senior Citizens’ Homestead, Senior Citizens’ Assessment Freeze, Disabled Persons’, Disabled Veterans’, and Returning Veterans’ exemptions. Each has its own eligibility rules; a homeowner should not assume that one exemption automatically produces another.

Use the 2026 renewal information carefully

Will County says 2026 renewal applications were mailed April 10 and that 2025 assessments are payable in 2026. The office also notes that tax rates have not yet been established when assessments are posted. That distinction matters when estimating a future bill.

Bring the right property details to a question

Have the PIN, address, occupancy information, and bill available. The Supervisor of Assessments offers a property search by PIN and address; the Treasurer is the source for payment status, copies, and bill questions.

Keep your ownership record organized

Property Records of Illinois may help a homeowner review available deeds, sales, tax, mortgage, lien, and property information in one report. Official Will County staff determine exemption eligibility and answer assessment questions.
