What exemptions can I get on my tax bill?

The state allows eight different exemptions for tax payers.

1) Homestead Limited/Owner Occupied:

To qualify, the taxpayer must own and live in the residence as of January 1 of the assessment year. Allows up to a maximum benefit of $6,000 assessment reduction. If you qualify for this exemption but have a zero credit listed on your tax bill, this means that your current assessment is below the 1977 value, 1977 being the statutory base year. Married couples living separately can split the exemption.


2) Senior Citizens Homestead General:

Exemption on owner-occupied residence as of Jan. 1 of the assessment year, be 65 years of age on or before December 31, with a $5,000 reduction in EAV. A prorated exemption for a senior citizen that occupies property as their principal residence after Jan. 1 of any assessment year. No restrictions for married couples living separately, both may qualify for the exemption.

3) Homestead Improvement: Exemption on owner-occupied residence as of Jan. 1 of the assessment year that prevents increases in assessed valuation due to new improvements of the existing structure or its rebuilding following a catastrophic event for up to 4 years. Maximum $ 75,000 (25,000 assessed value) in fair cash value of improvements.

4) Disabled Veterans: This applies when a disabled veteran owns and occupies the home, and the home has been approved for federal funds to purchase or construct special adaptations to suit the veteran’s disability. This is good for up to $70,000 in assessed valuation and is administered by the Illinois Department of Veterans Affairs.


5) Senior Citizen Assessment Freeze Homestead Exemption (SCAFHE): Taxpayer must own and occupy the property on January 1 of the year prior to application, be 65 years of age on or before December 31 of the assessment year, and have a household income of $65,000 or less. All income data is confidential. This exemption abates all increases in assessed valuation from market fluctuations on the tax bill even though the actual assessed value will change annually. However, even though your assessed value may not change, your tax bill may change due to changes in the tax rate. Married couples living separately, only one person may claim this exemption and for only one property.

7) Disabled Veterans Standard Exemption: Provides a reduction in a property’s EAV to a qualifying property owned by a veteran with a service-connected disability certified by the U.S. Department of Veterans’ Affairs. A $2,500 reduction in the EAV is available to a veteran with a service-connected disability of at least 50 % but less than 69% or a $5,000 reduction in the EAV is available to a veteran with a service-connected disability of at least 70%.

8)The SHEVD (35 ILCS 200/15-169) provides an annual reduction in the equalized assessed value (EAV) of a primary residence occupied by a veteran with a disability, or the veteran’s surviving spouse, on January 1 of the assessment year. The SHEVD amount depends on the percentage of the service-connected disability as certified by the U.S. Department of Veterans’ Affairs.
If the veteran has a service-connected disability of 30% or more but less than 50%, then the annual exemption is $2,500; if the veteran has a service-connected disability of 50% or more but less than 70%, then the annual exemption is $5,000; and if the veteran has a service- connected disability of 70% or more, then the residential property is exempt from taxation under this Code.

Your tax bill depends on two factors:

1) your property’s assessed valuation and 2) the amount of money your local taxing districts need to operate during the upcoming year. By law, assessments must be 1/3 of a property’s fair market value. Your assessment reflects the following: the most recent sale price, the cost of replacement, or the age, location and square footage of your property. Regardless of the method used to compute your assessment, the final figure is 1/3 of your property’s fair market value. As the market increases, the assessment must also increase. If the market drops, assessed value drops. However, if the assessed value does go up, this does not mean your tax bill will go up; it may remain the same or drop.

The State of Illinois Department of Revenue requires that all counties ensure that all properties within each county have an equalized assessed valuation of 33.33 percent of market value. This is done so that the taxing system is fair to all citizens. Your Township Assessor and the McDonough County Supervisor of Assessments are working to meet the Department of Revenue goals and requirements.

How fair is this system?: As fair as we can make it.

For property owners, your Township Assessor is the first person to review your property. By law, all township assessors are required to view every property in their jurisdiction every four years.

The assessors have several ways to complete assessments. These methods include: 1) Cost manuals 2) Actual market value based on recent “arms length” sales 3) Location, age, and square foot as it compares to similar properties in similar locations.

Your Township Assessor completes your assessment by June 15th of each year and files it with the Supervisor of Assessments. You may want to check the assessed value of your property at the Supervisor of Assessment’s office after the filing date. If you have a question about your assessment, you should speak with your Township Assessor first to determine how your property assessment was arrived at. After speaking with your Township Assessor, if you are not satisfied, then you may file an appeal of your assessment, once the assessments are published in newspaper, with the Board of Review. You may obtain an appeal form from the Supervisor of Assessment’s office. Your appeal may be based on Market Value or Equity. Other evidence may be submitted to support your basis.

The Board of Review consists of three members of the public who have been trained and tested in basic assessment practices. Their responsibility is to act on requests for tax exemptions and to hear and act on appeals.

If you disagree with the decision of the Board of Review, you may file an appeal of your assessment to the State Property Tax Appeal Board (P.T.A.B.). In this case a state hearing officer acts as a judge, hears evidence from both you and the county, and issues a decision based only on the evidence presented. Check with the Supervisor of Assessments for directions in appealing your assessment.

Your tax bill is based on a five step process: 1) The township assessor determines market value and divides by three, arriving at 1/3 of fair market value:

Market value - $55,000.00 55,000 
level of assessment 1/3               /3
of assessed value (rounded)        18,330


2) The Supervisor of Assessment reviews the township assessor’s values. If assessed values do not change the same as the market values, the Supervisor of Assessments is required to apply a township factor or multiplier to equalize values across townships:

Assessed value 18,330 
township factor             x 1.010
Assessed value   (rounded)        18,515

3) The Department of Revenue reviews county wide assessed values to see if they reflect changes in market value. If necessary, they apply a state multiplier to equalize the assessed values:
equalized value 18,515
state multiplier             x 1.000
Assessed value   (rounded)        18,515

4) Your equalized assessed value receives any exemptions you qualify for (see Section 11 - Exemptions):

Homestead Limited -6000
Homestead General             -4,000
Final Taxable Value       =  8,330

5) The total TAX RATE is applied to your final taxable VALUE to equal the amount of your tax BILL:
taxable VALUE   10,330
total TAX RATE (10.63) move decimal               x. 1063
tax BILL        $1,098.08

If you miss the deadline to appeal your assessment and you receive your tax bill and believe this is too high, you may protest your actual tax bill. This tax bill appeal process requires specific procedures, and you may want to work through an attorney.
