Frequently Asked Questions

As of the 2024 assessment year, there are 7,646 parcels in Campton Township.
State of Illinois law requires that all property be assessed at one-third (33.33%) of market value for property tax purposes; thus, to determine what market value your home has been assessed at, simply multiply your assessment by three.

For more information, see Understanding Your Assessment.
Not necessarily. Typically, your assessment will not be increased simply because it has just had a sale. Our concern is always accuracy and uniformity of assessment.

However, keep in mind that a sale above your assessed value may compel us to re-examine your assessment; if we find that the discrepancy is due to error, we may have to adjust the assessment to the level it should have been at in the first place.

Note that a sale that is above your assessment may also indicate a trend or change in an area's market value, possibly requiring us to re-examine all assessments in a neighborhood for correct and equitable levels of assessment.
You may qualify for certain exemptions that can affect your property taxes. For more information, go to Understanding Exemptions.
The first step is to decide whether or not your assessment is out of line with market value. You can investigate this in a number of ways:

Drop by the Campton Township Assessor's Office and review the assessments records for homes comparable to yours

Obtain an appraisal of your home and compare it to your assessment

Get an opinion from a realtor (Note: a realtor's opinion should only be used as a guideline when investigating market value)

Check our Property Assessment Online Database for assessments of homes you believe are comparable to yours.
Any new construction you do on your home that increases its market value must be reflected in your assessment. This can include (but is not limited to) additions, decks, porches, et al...

Upon receiving a copy of your construction permit, a member of our staff will flag your property for and inspection for the following year. Since your home is assessed based on its status as of January 1st of each year, our inspections are always performed during the calendar year following the permit date; see Understanding Your Assessment for more information.

After inspection, we will add your new construction to your assessment. However, if you own and occupy your home as your principal residence, you will qualify for the Home Improvement Exemption. The HIE exempts you from being taxed on that portion of your assessment that represents your new construction.; the maximum amount that will be exempted is $25,000, and the Home Improvement Exemption expires after four years.

How to apply:

Contact our office or the Kane County Supervisor of Assessments Office and request a Seniors' Exemption (also known as the Homestead Exemption) application form.
What it is:

An exemption that freezes the assessment of qualifying seniors. Once frozen, the assessment can only increase by whatever assessment multipliers are placed on the neighborhood or Township as a whole.

Keep in mind, however, that you must re-apply for the Freeze each year. If you no longer qualify during a particular year, your property could be subject to reassessment for current market value.

Who qualifies:

Seniors 65 years of age and older with an annual household income that meets the State's statutory criteria. You must own and occupy the property in question as your principal residence and be liable for the payment of property taxes.

Again, keep in mind that you must re-apply and qualify each year; if your annual household income should exceed the statutory maximum, your assessment will no longer be frozen and your property could be subject to reassessment.

How to apply:

Contact the Kane County Supervisor of Assessments Office and request help with applying for the Senior Citizens' Assessment Freeze.
What it is:

A four-year exemption on assessment increases that are due to new construction to your home, up to the statutory maximum of $25,000 in assessed value.

Who qualifies:

If you add a deck to your home that increases your assessment by $2,000, you will fall well under the $25,000 maximum; no portion of the $2,000 assessment increase will be taxable for four years.

However, if you add an addition that increases your assessment by $30,000, then you will exceed the $25,000 maximum; in this case, the first $25,000 of your $30,000 assessment increase will not be taxable for four years, but the remaining $5,000 will show up on your tax bill immediately.

How to apply:

You automatically receive your Home Improvement Exemption if you meet the above qualifications; no application is necessary.

ASSESSOR'S OFFICE

Tax Process

Many people assume that the Assessor sets their tax bill. But nothing could be further from the truth. The Assessor's Office merely sets assessments on real property based on market value. Our job ends there. Once we are done valuing your property, the assessment process ends and the Property Tax process begins.

We all receive many services from our government bodies. They provide the schools that educate our children, the police who protect our homes, even the roads and sidewalks that we use every day.

Your property tax bill helps pay for these and many other services. The cost of these services determines the tax rate for your tax district. Your property tax bill is then derived by multiplying your assessed value by the property tax rate for your area.

The steps of this process begin with the assessment of your home, followed by the levy of budgets by government bodies, and concluding with the collection process.
Each year, the Assessor's Office is required to review assessments for uniformity and accuracy before closing the assessment books. This process can include inspections of properties that have permits for new construction, reassessment of neighborhoods (or even individual homes) for uniformity and/or market value, and application of the annual Township Factor to all assessments in the township.

The annual Township Factor is a blanket multiplier recommended by the Kane County Supervisor of Assessments' Office (SA) that adjusts all assessments within a township for market value. Every year, the SA must conduct a sales-ratio study to determine what Township Factor is necessary to keep the median level assessments at the state-mandated level of 33 1/3%. If the SA's sales-ratio finds that a township is not at this statutory level, the SA will either recommend that the township's Assessor apply the Township Factor indicated by the sales-ratio study or, in certain cases, the SA may apply the Township Factor itself.

Once all assessments have been adjusted for the year, the Assessor's Office closes its books for the year. At this point, the Levy Process takes over.
Each governmental body listed on your tax bill must levy for the funds it needs to operate. In Kane, state law limits levy increases to 5% (or the rate of inflation, whichever is less) over the previous year's levy.

Note that this does not mean that individual tax bills will only increase by 5% or less each year.Your tax bill might be higher than this limit due to a reassessment of your home for market value, a reassessment due to an addition or remodeling, the loss of an assessment exemption, or a range of other factors.

The individual taxing bodies must set their levies and then submit them to the County Clerk for approval. Once approved, the County Clerk then calculates the dollar amount of the levies against the dollar amount of the assessed values for the tax district in question. The ratio of levy amount divided by total assessed value yields the tax rate for the tax district.
Next, the County Clerk multiplies your assessment (minus any appropriate exemptions) by your tax rate to determine your property tax bill.

The County Treasurer sends out all property tax bills on May 1st of each year.

Your property tax bill may be paid in two installments: the first installment is due June 1st; the second installment is due September 1st.
