Jersey County Property Tax: Rates, Exemptions, and Payment

Jersey County property tax bills are calculated by multiplying your home’s equalized assessed value, minus any exemptions you qualify for, by the combined rate of every local taxing district that covers your parcel. Bills come from the Jersey County Treasurer in two installments each year, and several homestead exemptions and a senior deferral program can bring the amount down if you apply in time.¹

How Your Bill Is Calculated

Illinois has no statewide property tax rate. What you owe depends on your property’s equalized assessed value (EAV) and the combined rate set by the school district, fire district, township, library, and other local bodies that serve your parcel.² The math runs in five steps:

Start with the property’s fair market value — what it would sell for in an open transaction.
Multiply by one-third. Illinois law requires most property to be assessed at 33⅓% of market value.³
Apply the state equalization factor. The Illinois Department of Revenue may add a multiplier to bring the county’s overall assessments in line with the one-third level, producing the EAV.⁴
Subtract any homestead exemptions you qualify for.
Multiply the remaining EAV by the composite tax rate for your location.

A $150,000 home has an assessed value of $50,000. Take the $6,000 General Homestead Exemption off, and the taxable EAV drops to $44,000. At a 7% composite rate, the bill is $3,080. The composite rate varies across the county because different parcels fall under different combinations of districts.

Assessments and How to Appeal Yours

Jersey County reassesses on Illinois’s quadrennial cycle, with a full reassessment every four years for counties under three million residents that use the township form of government.⁵ Between those years, the assessor can still adjust values for new construction, demolition, or significant market shifts. When your assessed value changes, you get a mailed notice. The appeal clock starts the moment it arrives, so read it quickly.

Start by contacting your township assessor directly. The assessor can make corrections, and many disputes end there without a formal hearing.⁶ If that doesn’t work, file a written complaint with the Jersey County Board of Review, a three-member panel that can hear complaints about property values or exempt status. If you disagree with their written decision, you can appeal further to the Illinois Property Tax Appeal Board or file a tax objection in circuit court.⁷

Bring hard evidence. Recent appraisals from a licensed appraiser, sales of comparable nearby properties within the last few years, and documentation of defects carry weight. Simply arguing the bill feels too high rarely succeeds.

Exemptions That Reduce Your Bill

Several homestead exemptions cut your EAV before the tax rate is applied. Each has its own rules, and you generally need to apply through the Jersey County Supervisor of Assessments office.

General Homestead Exemption

Any owner who occupies the property as a primary residence qualifies. In Jersey County, this reduces your EAV by up to $6,000.⁸ For most homes, the full $6,000 applies.⁹

Senior Citizens Homestead Exemption

Owners 65 or older by December 31 of the assessment year who occupy the property and pay its real estate taxes qualify for an additional reduction of up to $5,000 off their EAV.¹⁰ This stacks with the General Homestead Exemption, so a qualifying senior can take up to $11,000 off before the rate is applied.

Senior Citizens Assessment Freeze

The freeze locks your EAV at the level it was when you first qualified, blocking increases from rising property values. For the 2026 tax year, you need to be at least 65, own and occupy the property, and have a total household income of $75,000 or less. The threshold rises to $77,000 for 2027 and $79,000 for 2028 and beyond.⁸

The freeze does not stop the bill from going up entirely. If the tax rate rises or you add improvements, the bill still climbs. The freeze only prevents the EAV portion from growing due to general market appreciation. You must reapply every year by filing Form PTAX-340 with the county assessment office.

Persons with Disabilities Exemption

If you have a disability that prevents you from engaging in substantial gainful activity and is expected to last at least 12 months, you qualify for a $2,000 annual reduction in your EAV. The property must be your primary residence, and you must be liable for the taxes on it.¹¹ You cannot claim this exemption if you already receive the Veterans with Disabilities exemption.

Veterans with Disabilities Exemption

Veterans with a service-connected disability certified by the U.S. Department of Veterans Affairs receive an EAV reduction that scales with their rating:¹²

30% to 49% disability: $2,500 annual EAV reduction.
50% to 69% disability: $5,000 annual EAV reduction.
70% or higher: the first $250,000 of EAV is exempt from taxation entirely.

Because Illinois assesses at one-third of market value, that top-tier $250,000 EAV covers homes worth up to roughly $750,000. Surviving spouses of veterans whose death was service-connected also qualify for the $250,000 exemption. World War II veterans are exempt regardless of disability level for tax years 2024 and beyond.¹²

Senior Citizens Tax Deferral

If you qualify for senior exemptions and still can’t manage the bill, Illinois offers a separate deferral program that works like a low-interest loan from the state. For the 2026 tax year, you need to be at least 65 by June 1, have household income of $77,000 or less, and have owned and occupied the property for at least three years.¹³

The state pays your bill and places a lien on the property for the deferred amount plus 3% simple annual interest. You can defer up to $7,500 per year, and total deferrals cannot exceed 80% of your equity. The balance comes due when the property is sold or transferred. Applications are accepted between January 1 and March 1 each year.¹³

Paying Your Bill

Jersey County splits the annual tax into two installments. Due dates shift from year to year, so check the Treasurer’s website or your bill for current deadlines.¹ Mark both dates when the bill arrives. The most important number on the bill is the Parcel Index Number (PIN) in the upper right corner; you’ll need it for lookups, payments, and any correspondence with county offices.¹⁴

Payments can go through several channels:

In person at the Treasurer’s office in the Jersey County Government Building, or at participating Jerseyville banks (Farmers State Bank, Heartland Bank and Trust, Jersey State Bank, Jerseyville Banking Center, and Royal Banks) on or before the due date.¹
By mail with a check or money order and your tax stub. Postmark date counts as the payment date.
Online through the county’s portal. Credit and debit card payments typically carry a convenience fee in the range of 2% to 2.5%, while electronic check payments usually cost only a small flat fee.

Not receiving a bill does not excuse late payment; the obligation follows the property. If a mortgage company pays through escrow, confirm the lender is actually making timely payments. Escrow failures are more common than people expect, and the county holds you responsible either way.

If You Fall Behind

Unpaid property taxes in Jersey County accrue interest at 1.5% per month, or any fraction of a month.¹⁵ That’s 18% per year. On a $3,000 bill, a six-month delay adds $270 in interest alone. Once taxes are delinquent, local banks no longer accept them; payments go directly to the Treasurer or by mail.¹

At the annual tax sale, held in the auditorium of the Jersey County Government Building, third-party buyers bid on the unpaid taxes rather than the property itself. The buyer pays the delinquent amount and receives a tax lien certificate.¹

You still have time to reclaim the property after a sale. For most occupied residential properties, the redemption period is two and a half years from the sale date. Vacant non-farm land, commercial property, industrial property, and buildings with seven or more residential units get only one year.¹⁶ To redeem, pay the delinquent taxes plus a statutory penalty to the buyer through the Jersey County Clerk’s office.¹

If you let the redemption period expire, the tax buyer can petition the court for a deed. Once a tax deed issues, ownership is gone. Between the 1.5% monthly interest before the sale and penalties during redemption, even a modest bill can grow into a five-figure problem within a few years.
